Find the surface area of the following figure with the given dimension

Answers

Answer:

435 in.²

Step-by-step explanation:

Surface area of the square pyramid = area of the square base + ½(Perimeter of base)(slant height)

Area of base = s²

s = 15 in

Area = 15² = 225 in²

Perimeter of the base = 4(15) = 60 in

Slant height = 7 in

Surface Area = 225 + ½(60)(7)

= 435 in.²

If mZIJK = 112°, what is mZIHK?

Answers

Answer:

m<IHK = 68°

Step-by-step explanation:

In an inscribed quadrilateral, opposite angels are supplementary. This means that the sum of the opposite angles in am inscribed quadrilateral equals 180°. One is the supplement of the other.

Therefore,

m<IHK = 180 - m<IJK

m<IHK = 180° - 112°

Answers

Answer:

sure Gigi,    as below

Step-by-step explanation:

A)

we want to know the rates.  so this like like in MPH (Miles per hour)  or feet per second but something that we can compare each walker with the other .... so we want some type of scale that makes sense.  what are the given units.... they are distance in miles and time in hours.. so maybe MPH would work for this.

there is a very good, basic formula that you should just remember for this type of problem... I can it the dirt formula... partly b/c it's dirt easy.. and partly b/c it really is about how much dirt you cover.. i mean.. how far you do... in a distance .. and you can use any unit you want...  like we'll use miles here.. for our units..  we will you d = rt  where d= distance , r= rate and t = time.

d = rt.... notice the formula looks a lot like the word  "dirt"   handy huh...

use it to make all the walks have a number...  their rate... the r in the formula... to compare with,  so use your algebra skills to rearrange the formula... to

d/t = r      now we can plug in each of the walkers and get a rate to comparr them  

Aisha  5/2 = r  so 5/2 MPH

Bob  7.5 / 5 = r  so 7.5 = 15/2   then (15/2)  /  5   = (15/2) * (1/5)  ( cross cancel the 15 and 5  so you get  (3/2) * (1/1) =  3/2

Bob = 3/2 MPH

Cora = 9 / 3.6    or   9 / 3[tex]\frac{6}{10}[/tex]   or  (9/1) / ([tex]\frac{36}{10}[/tex])  or  (9/1) * (10 / 36) cross cancle the 9 and 36 so you get     (1/1) * ( 10 / 4)   = 10/4 = 5 /2

Cora = 5/2 MPH

Dylan = 3.75 /2.5  or  3 [tex]\frac{3}{4}[/tex] / 2[tex]\frac{1}{2}[/tex]  or  (15/4) / (5/2)  or (15/4 ) * (2/5)  cross cancel the 2 and 4 and also cross cancel the 15 and 5    then,   (3/2) * ( 1/1)= 3/2

Dylan = 3/2 MPH

            MPH

Aisha = 5/2

Bob   =  3/2

Cora  =  5/2

Dylan = 3/2

you can now make fair comparisons among the 4 people

B)

d = rt

d/t = r

Emilio  =  19.2 / 6   or 19[tex]\frac{2}{10}[/tex] / 6  or  (192/10 ) / (6/1)  invert and multiply to bring the denominator up   (192/10) *  (1/6)  cross cancle 6 into 192 = 32

so(32/10) * ( 1/1) = 32/10  or  16/5 =  3[tex]\frac{1}{5}[/tex] or 3[tex]\frac{2}{10}[/tex] which is  3.2 MPH

Fala  = 10.5 / 3   or  10[tex]\frac{1}{2}[/tex] /3   or  [tex]\frac{21}{2}[/tex] / 3   or   (21/2) / (3/1)  invert and multiply the denominator    (21/2) * ( 1/3)  , cross cancel 3 and 21    (7/2) * ( 1/1)  = 7/2

so now you have all the rates.. how fast they are walking.  in Miles per hour and that's what the scale of the number line is.. so, good.. just mark each of their speeds

Bob and Dylan = 3/2 or  1.5 MPH... pretty slow.. huh :P

Cora and Aisha = 5/2 or 2.5 MPH  faster but not fast

Emilo 3.2 MPH  pretty quick

Fala 3.5 MPH  she's fast. :D  speed walking

3.2 on the number line is not marked.. 3.25 is.. so just a bit below the 3.25 mark.. that's 3[tex]\frac{1}{4}[/tex] , see it?

all the others are marks on the number line.. just count marks for 1//2s

A biologist found the wingspans of a group of monary butterflies to be normally distributed with a mean of 52.5 mm and a standard deviation of 2.5 mm. What percent of the butterflies had the following wingspans? A. Less than 48.9 mm B. Between 49 and 55

Answers

Answer:

A. 7.5%

B. 68.26%

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 52.5 mm and a standard deviation of 2.5 mm.

This means that [tex]\mu = 52.5, \sigma = 2.5[/tex]

A. Less than 48.9 mm

The proportion is the pvalue of Z when X = 48.9. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{48.9 - 52.5}{2.5}[/tex]

[tex]Z = -1.44[/tex]

[tex]Z = -1.44[/tex] has a pvalue of 0.075

0.075*100% = 7.5%, which is the answer.

B. Between 49 and 55

The proportion is the pvalue of Z when X = 55 subtracted by the pvalue of Z when X = 49. So

X = 55

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{55 - 52.5}{2.5}[/tex]

[tex]Z = 1[/tex]

[tex]Z = 1[/tex] has a pvalue of 0.8413

X = 49

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{49 - 52.5}{2.5}[/tex]

[tex]Z = -1[/tex]

[tex]Z = -1[/tex] has a pvalue of 0.1587

0.8413 - 0.1587 = 0.6826

0.6826*100% = 68.26%, which is the answer.

The percent of the butterflies had the given wingspans are;

A) 7.5%

B) 76.64%

We are given;

Population mean; μ = 52.5 mm

Population standard deviation; σ = 2.5 mm

Formula for z-score is;

z = (x' - μ)/σ

A) For less than 48.9 mm,P(X' < 48.9);

z = (48.9 - 52.5)/2.5

z = -1.44

From online p-value from z-score calculator, we have;

P(X' < 48.9) = 0.075 or 7.5%

B) For x' between 49 and 55, P(49 < X < 55)

At x' = 49;

z = (49 - 52.5)/2.5

z = -1.4

Z-score at x' = 55;

z = (55 - 52.5)/2.5

z = 1

From online p-value from z-score calculator, the p-value between the two z-scores is;

p = 0.7664 or 76.64%

What is the slope of this graphed line?

Answers

Answer:

[tex]-1\frac{1}{2}[/tex]

Step-by-step explanation:

We have two coordinate points and are asked to find a slope.

When finding slope, we can use the formula listed :

[tex]\frac{y^2-y^1}{x^2-x^1}}[/tex]

To understand what the variables are, you can take this :

[tex](x^1,y^1)[/tex]

[tex](x^2,y^2)[/tex]

Substitute the points :

[tex](-1,4)[/tex]

[tex](5,-5)[/tex]

Now substitute it into the formula :

[tex]\frac{-5-4}{5-(-1)}[/tex]

[tex]\frac{-3}{2}[/tex]

[tex]-1\frac{1}{2}[/tex]

Answer:

Step-by-step explanation:

find the slope m  by using the slope formula

m = (y2 - y1) / (x2 - x1)

Point1 = ( -1,4)  where it takes the form (x1,y1)

Point2 =(5, -5) where it takes the form (x2,y2)

notice the form is important

m = (-5 -4) / (5 - (-1))

m = -9  /  ( 5 +1 )

m = -9 / 6

m = - 3/2

Put the following equation of a line into slope-intercept form, simplifying all
fractions.
8x – 12y = -96

Answers

Answer:

2/3x+8=y

Step-by-step explanation:

8x-12y=-96

8x+96=12y

8/12x+8=y

2/3x+8=y

The equation 8x – 12y = -96 of a line into slope-intercept form, simplifying all fractions, is 3y = 2x + 24.

What is equation?

Two expressions with variables or integers are said to be equal when they are declared to be in an equation. Since equations are essential questions, efforts to methodically find answers to these questions have been the inspiration for the development of mathematics.

Given:

The equation, E = 8x – 12y = -96,

The standard intercept form of a line,

[tex]y = mx + c[/tex]

Here m is the slope,

For this form, arrange the equation,

– 12y = -8x - 96

(Do multiplication of  -1/ 4 on both sides)

3y = 2x + 24

Therefore, the equation 8x – 12y = -96 of a line into slope-intercept form, simplifying all fractions is 3y = 2x + 24.

The answer is 392. Ok so first you turn 56% into a decimal. You do that by moving the decimal place two spaces to the left. So that leaves you with 0.56. Next you multiply 0.56 x 700, because in math the word “of” means to multiply. 0.56 x 700 = 392. So 56% of 700 is 392. I hope this helps! :)

. An oil refnery is located on the north bank of a straight river that is 2 km wide. A pipeline is to be constructed from the refnery to storage tanks located on the south bank of the river 6 km east of the refnery. The cost of laying pipe is $400,000ykm over land to a point P on the north bank and $800,000ykm under the river to the tanks. To minimize the cost of the pipeline, where should P be located

Answers

Answer:

The point P should be located at 0,51 Km from point B, to minimize costs

Step-by-step explanation:

The oil refinery ( point A ) the opposite point ( B) in the south bank, and the storage tank (point C) these three points shape a right triangle. Let´s call x the distance between point A and point P ( the arriving point of the pipeline in the south bank ) then:

Cost = cost of pipeline in-ground* ( 6 - x ) + cost of pipeline in water* L

where L is the hypothenuse of the right triangle  ( A , B , P )

Cost ($) = 400000 * ( 6 - x ) + 800000 * √ 2² + x²

C (x) = 400000* ( 6 - x ) + 800000* √4 + x²

C(x) = 2400000 - 400000*x  + 800000* √4 + x²

Tacking derivatives on both sides of the equation

C´(x) = - 400000 + 800000* ( 2x)/√4 + x²

C´(x) = 0         - 400000 + 1600000*x / √4 + x²  = 0

- 400000* (√4 + x² )  + 1600000*x  = 0

- (√4 + x² ) + 4* x = 0

- (√4 + x² )  = - 4*x

Squaring both sides

4 + x²  = 16*x²

15*x² = 4

x² = 4/ 15

x = ± √0,27

x = ± 0,51

We should dismiss the negative solution

x = 0,51 Km

The point P should be located at 0,51 Km from point B

The time requirements (in hours per unit) and the profit per unit for each product are as follows. Product A Product B Product C Dept. I 2 1 2 Dept. II 3 1 2 Dept. II 2 2 1 Profit $18 $12 $15

Answers

Answer:

a)

product A = 12O units

Product B = 220 units

product C = 280 units

b) $9000  = max/largest profit

c) No resource left

Step-by-step explanation:

Available hours

Dept. I = 1020

Dept. II = 1140

Dept. III = 960

Total available hours = 3120 hours

products produced by each department

                  product A         Product B        Product C

Dept. I            2                           1                    2

Dept. II           3                           1                    2

Dept. III          2                           2                     1

profits             $18                      $12                 $15

Determine how many units of each product to be produced to attain maximum profit

let each product be represented as : x , y , z

2x + y + 2z  = 1020 -------- ( department  A ) --- 1

3x + y + 2z  = 1140   -------- ( department B ) --- 2

2x + 2y + z = 960    --------- ( department c ) ---- 3

max profit : 18 x + 12y + 15 y

solving  equation 1 from  2

x = 120

solve equation 2 from 3 simultaneously

x - y + z = 180

-y + z = 60

solve equation 1 and 3

-y + z = 60

∴ z =  60 + y

back to equation 1

2( 120 ) + y + 2( 60 + y ) = 1020

240 + y + 120 + 2y = 1020

y = (1020 - 360 )/ 3 = 220

therefore ; z = 60 + 220  = 280

amount of each product to be produced to gain maximum profit

product A = 12O units

Product B = 220 units

product C = 280 units

ii) The largest profit

18 ( 120 ) + 12(220) + 15 ( 280 ) =  $9000
