Step-by-step explanation:

Answer:

23°

Step-by-step explanation:

For this scenario say point G is the center point,

If we look to the left, we see angle FGE has a value of 23

and in this case angle CGD is a congruent angle to FGE therefore the two angles must be the same

so therefore angle CGD should be 23 degrees

Answer:

1548.7 in³

Step-by-step explanation:

Given that :

Volume of ball = 524 in³

Volume of a cube = s³

Where, s = 12.75 inches

Volume of cube = 12.75 * 12.75 * 12.75 = 2072.671875 in³

The volume of air inside the cube :

(volume of cube - volume of ball)

(2072.671875 - 524) in³

= 1548.671875 in³

= 1548.7 in³ (nearest tenth)

Answer:

roots:  2 ± (1/2)√42

                                                                  -8

axis of symmetry:  x = -b/(2a)  is  x = ---------------- = 2

                                                                 2(-2)

vertex:  (2, f(2) ) = (2, -2(2)^2 + 8(2) + 13 ), or (2, 21)

Step-by-step explanation:

First, let's determine the roots of this quadratic, using the quadratic formula.  Here the coefficients are -2, 8, 13.

Thus, the discriminant b^2 - 4ac is 8^2 - 4(-2)(13), or 64 + 104, or 168.  Because the discriminant is positive, we know that there are two different real roots.

They are:

        -8 ± √168                       -8 ± 2√42

x = ---------------------  or  x =  ---------------------  =  2 ± (1/2)√42

               -4                                     -4

Answer:

5m  the last option is correct

Step-by-step explanation:

by phythagorean theorem

hypotenuse^2=base^2+altitude^2

hypotenuse ^2= (4)^2+(3)^2

                        =16+9

                        =25

taking square root on both isdes

 hypotenuse=5 m

Step-by-step explanation:

Answer:

The answer should be B

Step-by-step explanation:

Assuming x is the 2 then 2+7 should equal 9 and 9 would represent less than the amount Roy wanted to work out which would be the ideal one for him since he wanted to work out less than 18 hours.

Answer:

e, f

Step-by-step explanation:

A measurement of variability is an overview of the amount of dispersion  in a dataset. The measures that can describe the variation on a data set are Range, Interquartile Range, Variance, and Standard Deviation.

So ,The among the given options the e. Interquartile range f. Range

Range of dataset is the difference between the larges and smallest elements in the dataset .

The middle of the data between the upper and lower quartiles are called the inter-quartile range. That means that 50 percent of data points between Q1 and Q3 are included within the interquartile range.

Given :

Teresa is going to make 3 batches of cookies.

She needs 3/4 milk for each. Her measuring cup only holds 1/4 gallon.

To Find :

How many times will she need to fill up.

Solution :

Amount of milk need per batch, A = 3/4 gallon.

Measuring cup only holds, m = 1/4 gallon.

Number of times she need to fill up,

n = A/m = (3/4)/(1/4) = 3

Now, number of batches are three.

So, number of time she need to fill up in three batch.

[tex]N = n \times 3 \\\\N = 3 \times 3 \\\\N = 9[/tex]

Therefore, this is the required solution.

Answer:

100 small fish will be in 200 gallons of water. 40 large fish will be in 200 gallons of water.

Step-by-step explanation:

200/10=20

20*5=100 small fish

200/40=5

5*8=40 large fish

100+40=140 total fish

small fish/large fish=100/40=10/4=5/2 is the ratio

Answer:

The set of all positive integers equal to or greater than 1

Step-by-step explanation:

n can take on the integer values 1 ... ∞

The formula for the nth term is a(n) = a(1) + 2(n - 1)

First term:  n = 1.  Then a(1) = 3 + 2(0) = 3 (as expected).

5th term:  n = 5.  Then a(5) = 3 + 2(5 - 1) = 3 + 8 = 11

...

and so on.

Answer:

Step-by-step explanation:

hello :

27 ×32 = 3x×2y

means : 27 ×32 = 6xy

xy= (27 ×32)/6

xy = 144

but : 144 =12² = (4×3)²=(2²×3)²

144=2^4 ×3²

so : xy = 2^4 ×3²

if  x and y the integere numbers so x and y are the divisors of 144

Answer:

(-5, 2)

Step-by-step explanation:

Answer:

Angle 3 = 115°

Angle 4 = 22°

Angle 5 = 43°

Angle 6 = 115°

Step-by-step explanation:

These two triangles are congruent by SSS. It is given that two sides are congruent already, and by the reflexive property, they share a side and therefore have a third congruent side.

By CPCTC, all of their angles and sides are also congruent. And by the triangles angle sum theorem, side 3 and 6 must equal 115°

~~~

Have a nice day. Feel Free to ask questions. Spread the love.

Step-by-step explanation:

4 = 22⁰

5 = 43⁰

3 and 6 are same

kite total angles = 360⁰

so, to find 3 and 6, we need to subtract all angles we have and devide it with 2 because we need to find 2 angles...

360-22-22-43-43= 230

3 and 6 = 230 ÷ 2

= 115⁰

Answer:

Answer:

? = 7.2

Step-by-step explanation:

Remark

Is that a misshapen circle or is it an ellipse? I'm going to assume it is a circle, but if I am wrong, leave a comment. A tangent will meet a diameter's end at right angles which allows you to use the Pythagorean theorem.

Formula

a^2 + b^2 = c^2

Givens

c = 12

a = 9.6

b = ?

Solution

c^2 - a^2 = b^2

144 - 92.16 = b^2

b^2 = 51.84                          Take the square root of both sides

sqrt(b^2) = sqrt(51.84)

b = 7.2

Answer:

The answer is 256

Step-by-step explanation:

You just have to get the divisor  

(

40

)

and multiply by the quotient  

(

6

)

, then add the remainder  

(

16

)

.

So we have:  

(

40.6

)

+

16

=

256

The number is 276.

Let us assume that the number is N.

So according to the question we can say that

N= 15(18) +1

because dividend= divisor x (quotient) + remainder and quotient is odd.

 So now, N (on expanding) =15 × 18 + 5

                                              = 275

So if N is divided by 15 the remainder would be  275+1=276.
