The area of a triangle is 92 square inches. The base is 23 inches. What is the height in inches? Do not include units in your answer.

Answers

Answer:

34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?

Answer:

Step-by-step explanation:

We can use the formula for the area of a triangle, to help us find the height:

Area=12⋅b⋅h

Using the formula for area, we can solve for the height by plugging in the information we have about the area and the base:

92=12⋅23⋅h

Isolate h by multiplying both sides by 2 and dividing both sides by 23.

hh=2⋅9223=8

The height is 8 inches.

You randomly choose one of the chips. Without replacing the first chip, you choose a second chip. Find
the probability of choosing the first chip, then the second chip.
White and not a Green


Answers

Answer:

probability = 0.07777

Step-by-step explanation:

there are 10 chips

white  1

red     4

green 2

blue   3

the probability of choosing the W chip is 1/10  or  0.10      

now there are 9 chips left (the first chip was not replaced)

the probability of choosing a non-green chip is (9-2)/9 =  7/9  = 0.7777  

so now I THINK you multiply the two probabilities to get the total probability

probability = 0.1 ·0.7777

probability = 0.07777    which makes sense it has to be less than 0.1

Answer:

1/15

Step-by-step explanation:

2/10 x 3/9= 6/90

6 divided by 6

90 divided by 6

=1/15

How much money is 15% of $ 14.99

Answers

Answer:

The discount is $2.25 and the final price will be $12.74

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 14.99 × 15/100

Discount = 14.99 x 0.15

You save = $2.25

Final Price = Original Price - Discount

Final Price = 14.99 - 2.2485

Final Price = $12.74

hope this helps and is right. p.s. i really need brainliest :)

Answer:

$12.74

Step-by-step explanation:

15% of 14.99 dollars

14.99-2.25=12.74

Explain how to find mode, range, and mean

Answers

Step-by-step explanation:

The mean is the usual average, so add all of the numbers and then divide.

The mode is the number that is repeated more often than any other.

The range is the largest value and smallest value subtracted.

Answer:

Answer bellow

Step-by-step explanation:

To find mean(average) get all the numbers and and add them together after devide the added number by the number of numbers

To find mode rewrite all the numbers and look for numbers that are repeating (it can be more than one)

To find range take the biggest number from the data set and subtract it from the smallest number in the data set

Please help!!! Evaluate sin(x)
A. 2.125
B. 0.4706
C.0.8824
D.0.5333

Answers

Answer:

sin x = 0.4706

Step-by-step explanation:

Given that,

Height, h = 8

Base, b = 15

Let H be the hypotenuse of the triangle. Using Pythagoras theorem,

[tex]H=\sqrt{8^2+15^2} \\\\H=17[/tex]

We know that,

[tex]\sin\theta=\dfrac{h}{H}[/tex]

So,

[tex]\sinx=\dfrac{8}{17}\\\\\sin x=0.4706[/tex]

So, the correct option is (b).

3. Write the equation of the circle with a center at (-6, 1) and an area of 7n.

A Q(x + 6)^2 + (y - 1)^2 = 14
B (x - 6)^2 + (y + 1)^2 = 49
C (x + 6)^2 + (y - 1)^2 = 49
D (x + 6)^2 + (y - 1)^2 = 7
E (x - 6)^2 + (y + 1)^2 = 7

Answers

Answer:

D [tex] (x +6) ^2 +(y-1)^2 =7 [/tex]

Step-by-step explanation:

Center of the circle (h, k) = (-6, 1)

Area of the circle [tex] =\pi r^2 [/tex]

[tex] 7\pi=\pi r^2 [/tex]

[tex] \frac {7\pi}{\pi} =r^2 [/tex]

[tex]r^2=7[/tex]

[tex]r=\sqrt 7[/tex]

Radius [tex] r=\sqrt {7}[/tex]

Equation of circle in center radius form is given as:

[tex] (x - h) ^2 +(y-k) ^2 =r^2 [/tex]

Plugging the values of h, k and r in the above equation, we find:

[tex] [x - (- 6)] ^2 +[y-1 ]^2 =(\sqrt {7})^2 [/tex]

[tex] (x +6) ^2 +(y-1)^2 =7 [/tex]

A scale model of an object has a scale of 1cm : 2ft. The actual object is 11 feet tall. How tall is the model?

Answers

Given:

The scale model of an object has a scale of 1cm : 2ft.

The actual object is 11 feet tall.

To find:

The height of the model.

Solution:

It is given that the scale model of an object has a scale of 1cm : 2ft and the actual object is 11 feet tall.

Let the height of the model be x cm.

[tex]\dfrac{x\ cm}{11\ ft}=\dfrac{1\ cm}{2 \ ft}[/tex]

[tex]x\ cm=\dfrac{1 \ cm\times 11\ ft}{2 \ ft}[/tex]

[tex]x\ cm=5.5\ cm[/tex]

Therefore, the model is 5.5 cm tall.

3/4 Ravi is as tall as Sam, Mike is as tall as 5/3 Ravi. Find the ratio of Mike's height to Sam's height.​

Answers

Answer: The ratio of Mike and Sam Heights are  S:M=5:4

Step-by-step explanation:

Ravi is 3/4 as tall as Sam.

Consider the equation is  3/4 *R=S

Mike is 5/3 as tall as Ravi.

Then, the equation is 5/3 *M=R

Solve the two equation to find ratio of mikes and sam height.

3/4*R=S   Eq(1)

Rearranging eq (1) for R

R=4/3 *S      Eq(3)   made from eQ (1)

R=5/3*M   Eq(2)

Comparing   Eq 2 &3  equations

4/3*S=5/3*M

S/M=(5/3)*(3/4)
