The height of the heater is about 89.3 in.

You can solve this problem with the Pythagorean Theorem. The base is a square. So half way across the middle will the right under the tip of the pyramid. We can use the measurement with the slant height to write and solve the equation below.

23.8^2 + x^2 = 90.1^2
x will be about 89.3.

Answer:

Height of the pyramid is 86.9 in

Step-by-step explanation:

The length of the pyramid, the height and the slant height forms a triangle.

Given that

L = The length of one side of the base = 23.8 in.

S = The slant height of the pyramid = 90.1 in.

The height of the pyramid is calculated as follows.

Let H = height of pyramid.

Using Pythagoras theorem

S² = H² + L²

Substitute values

90.1² = H² + 23.8² --- collect like terms

H² = 90.1² - 23.8²

H² = 8118.01 - 566.44

H² = 7551.57 --- Take Squareroot of both sides

√H² = √7551.57

H = √7551.57

H = 86.899 in

H = 86.9 in --- Approximately.

Hence, the Height of the pyramid is 86.9 in

A scale on a blue print drawing of a house shows that 10 1010 centimeters represents 2 22 meters. What number of actual meters a
Ivenika [448]

Answer:

On Blue print 18 centimeters represents <u>3.6 meters</u>.

Step-by-step explanation:

Given:

Scale is 10 cm = 2 m

We need to find the number of actual meters are represented by 18 1818 centimeters on the blue print.

Solution:

Now we know that;

10 cm = 2 m

so 1 cm = Number of meters in 1 cm.

By using Unitary method we get;

Number of meters in 1 cm = \frac{2}{10}=0.2\ m

Now we know that;

1 cm = 0.2 m

18 cm = Number of meters in 18 cm.

Again by using Unitary method we get;

Number of meters in 18 cm = 0.2\times 18 = 3.6\ m

Hence On Blue print 18 centimeters represents <u>3.6 meters</u>.

Write an equation for the translation of y = |x|. 13 units down
olga55 [171]
The idea for transitions for an equation like this is
y = m|x - h| + k
where m = slope
h = how much left or right (note the negative)
k = how much up or down

moving 13 down would mean
k = -13

so
y = |x| - 13
