tan23=h1/500
h1=500tan23
tan50=h2/500
h2=500tan50
The height of the building is h1+h2 so

The base of a triangle is 24 millimeters and the height is 7 millimeters. What is the area of the triangle?
Answer:
84
Step-by-step explanation:
area of a triangle is represented by this equation: A= 1/2(b x h)
so we plug in the base for b and the height for h to get A=1/2(24 x 7) and now we solve accordingly. 24 x 7 is 160, and 160 x 1/2 is 84.

Step-by-step explanation:
We write out the question 2 1/4 - 3/4 = ?
Then you use the model A below
Next you can add on from the smaller number 3/4 being step 1
And you use model B to find step 2 + step 3 as it reminds you that there is 1/4 in total time being the smallest box out of the sum.
step 1 = 3/4 + 1/4 = 1 = 1/4 is missing in A model box
step 2 = + 1 (to make 2) = 1 is left in B model box
step 3 is + 1/4 is left in B model box
Then add the up = 1/4 + 1 + 1/4 = 1 1/2

Handy Dandy grocery is having a sale this week. If you buy a five pound bag of apples for the regular price $2.99. You can get another bag for $1.79.
Answer:
The answer is below
Step-by-step explanation:
A grocery store is having a sale this week. If you buy a 5-pound bag of apples for the regular price, you can get another bag for $1.79. If you buy a 5-pound bag of oranges at the regular price, you can get another bag for $2.49. Write an equation to find the discount for each situation.
Regular price for apples is $2.99
Regular price for oranges is $3.99
Solution:
The original price of the apples = $2.99 , price at a discount = $1.79
Discount for A= original price - price at a discount = $2.99 - $1.79
Discount for A= $1.20
x = ($1.79 / $2.99) * 100% = 59.9%
Discount in percentage = 100% - 59.9% = 40.1%
The original price of the orange = $3.99 , price at a discount = $2.49
Discount for R = original price - price at a discount = $3.99 - $2.49
Discount for R = $1.50
x = ($2.49 / $3.99) * 100% = 62.4%
Discount in percentage = 100% - 62.4% = 37.6%

What is the surface area of a dome (a half sphere) with a radius of 6 meters?
72 pi meters squared
48 pi meters squared
24 pi meters squared
144 pi meters squared
Answer: 72π meters squared.
Step-by-step explanation: Given that the radius is 6 meters, use the sphere surface area formula to find the surface area of the half-sphere;
Replace the value in the formula: A=4πr² → A=4π6²Solve the exponent first: A=4π6² → A=4π36The order of the multiples does not affect the total, so we can multiply 4 times 36 first: A=4π36 → A=144π144π is the surface area of the whole sphere, so half the sphere will be 72π. In conclusion, the surface area of the dome will be 72π meters squared.Zack drew a scale drawing of a house and its lot. The backyard is 15 inches wide in the drawing.

Answer:
203.2cm
Step-by-step explanation:
De la pregunta anterior,
1 pulgada = 2.54 cm
80 pulgadas = x
Multiplicar cruzada
x = 80 × 2.54 cm
x = 203.2 centímetros
La medida de su relación es 203.2cm.
The diameter of a given circular fountain is 203.2 centimeters.
It is given that a circular fountain has a diameter of 80 inches.
What is the diameter?A diameter is a distance that passes through the center of the circle to the endpoint of a circle.
1 inches = 2.54 cm
Let 80 inches = x cm
x = 80 × 2.54 cm
x = 203.2 centimeter.
Therefore, the diameter of a given circular fountain is 203.2 centimeters.
