Because one angle is shared between the smaller and larger triangles, this angle is clearly equal. In addition, their sides surrounding that angle are in the same ratio, so these triangles are similar by SAS similarity, with a ratio of 2. This means the sides of the big triangle are twice as long as the ones of the small triangle. As a result, x is equal to 46*2=92.

-4x-11. Plug -15 in for x into the equation. -4(-15)-11. That gives you 49. Therefore, making choice C correct.

QUESTION POSTED AT 14/12/2019 - 05:36 PM

The costs of the digital Camera is $185.00 dollars
The sales tax rate is said to be 5.7%.
Now, let’s solve for the final price by simply adding 5.7% to the original price.
Solutions:
=> 185 dollars – original price
=> 5.7% - sales tax
=> 5.7% = 5.7 / 100 = .057
Let’s get the 5.7% value
=> 185 * .057 = 10.545
Now, we have the value, let’s add this to the original price of the camera
=> 185 + 10.545 = 195.545
Thus, the final price with the sales tax is 195.55

Given Situation: Jack shells 315 peanuts in 15 minutes.
Let’s analyze this given situation to be able to get the correct unit rate that we need:
In 15 minutes Jack was able to shell out around 315 peanuts. Now, let’s see how many peanuts he can shell in every minute.
=> By simply dividing 315 by 15 , we can get the correct answer.
=> 315 peanuts / 15 minutes
=> 21 peanuts per minute.
Thus, Jack can shell out 21 peanuts / minute.

Slope intercept form equation:

y=mx+C

----------------------

We already know that m=-4. Now, let's find the value of C.

--------------------

m=-4, and when x=-1, y=5.

(5)=(-4)*(-1)+C

5=4+C

5-4=4+C-4

1=C

-----------------

Therefore the slope intercept form of the function is:

**y=-4x+1**

y=mx+C

----------------------

We already know that m=-4. Now, let's find the value of C.

--------------------

m=-4, and when x=-1, y=5.

(5)=(-4)*(-1)+C

5=4+C

5-4=4+C-4

1=C

-----------------

Therefore the slope intercept form of the function is:

To find f(4), you just replace wherever x is with 4.

f(x) = 3x - 1

⇒ f(4) = 3*(4) - 1

⇒ f(4)= 12-1

⇒ f(4)= 11.

**f(4) = 11 is the final answer**.

I just followed the numbering list.

2) The volume of a cube is V = s^3 where s = side. So, V = 15^3 = 3375 cu. inches.

3) The volume of a prism is V = A*h where A = surface area and h = height. So, A = (120 sq.ft)(8 ft) = 960 cu. ft.

4) 1246 cu. cm (1 mL/1 cu.cm) = 1246 mL

5) volume

10) The volume of a cylinder is V = pi*h*(d/2)^2. So, V = 3.1416*4.5*(3/2)^2 = 32 cu. inches

There are several ways to solve this. I would use substitution. to do that you want to get the X in the bottom equation by itself. after that substitute that new equation for the x in 2x. so it would look like 2(new equation). solve that then you will find y. do the exact same thing to y to find x. if you're still confused, ask me.

**Answer:**

**Height to width is 3:4**

**Width to height is 4:3**

**Step-by-step explanation:**

A TV screen is 15 inches high and 20 inches wide.

Height of TV screen is 15 inches

Width of TV screen is 20 inches

To find ratio of Height to width

we replace the numbers in the ratio Height : width

15: 20

Divide both numbers by 5, so ratio becomes

3: 4

**Height to width is 3:4**

To find ratio of Width to height

we replace the numbers in the ratio Width : height

20:15

Divide both numbers by 5, so ratio becomes

Forgive me if I'm wrong, but here goes:

On Harold's test, he scores 34 points for his correct answers, and -6 points for incorrect answers. He would have gotten 28 points, but that's not the question.

34 is the first number, and I believe the next one is -6.

6 is negative because 1 point is deducted for each incorrect answer, which also means 1 point is subtracted for every incorrect answer. Because the question is asking for numbers and not an equation or expression, the subtraction is expressed as a negative symbol, hence negative six.

Hope I helped!
