Lydia is an architect. She has to design a courtyard garden inside a new hotel. On her blueprint, which is 1/20 the size of the actual garden, the width of the garden is 36 inches. What is the width of the actual garden?

Answers

Answer:

720 inches

Step-by-step explanation:

On her blueprint, which is 1/20 the size of the actual garden

the width of the garden is 36 inches.

What is the width of the actual garden?

Let width of the actual garden = x

1/20 of x = 36

1/20 * x = 36

x = 36 ÷ 1/20

x = 36 * 20/1

x = 720

x = 720 inches

The width of the actual garden = 720 inches

Camden is deciding between two parking garages. Garage A charges an initial fee of
$12 to park plus $4 per hour. Garage B charges an initial fee of $8 to park plus $5 per
hour. Let A represent the amount Garage A would charge if Camden parks for t
hours, and let B represent the amount Garage B would charge if Camden parks for t
hours. Write an equation for each situation, in terms of t, and determine the hours
parked, t, that would make the cost of each garage the same.

Answers

Answer:

4 hours

Step-by-step explanation:

A = 12 + 4t

B = 8 + 5t

12 + 4t = 8 + 5t

t = 4

The cost of each garage would be the same when Camden parked the car for 4 hours

Step-by-step explanation:

angle ACB = 180-130=50 degree

A circle has a secant AC and a tangent AD that intersect outside of the circle. If the
measure of ZA is 29° and the measure of BD is 43°, then determine the measure of
CD.

Answers

Answer:

CD = 101°

Step-by-step explanation:

The secant- tangent angle DAB is hlf the difference of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (CD - BD ) = 29° ( multiply both sides by 2 )

CD - BD = 58°, that is

CD - 43° = 58° ( add 43° to both sides )

CD = 101°

What is X equal to in this problem?

Answers

Answer: X=80

Step-by-step explanation:

Know that all angles COMBINED in a triangle is 180, so we can use the two angles to setup the equation for the last one, since the total angle must be 180 then x added to those angles must add up to 180.so we get the equation x+59+41=180.x+100=180, subtract 100 from both sides to isolate x.x=80.
X is 80 because the inside on a triangle always adds up to 180 while the outside is 360 so 51+49=100 so 100-180=80 boom the answer

Answer:

r=8

Step-by-step explanation:

3r+4+8r-2 = 90

11r +2 = 90

11r= 88

r= 8

The picture shows a complementary angle. Which means the angle will add up to 90 degrees. So to find the the value of r, take the two angles and add them up equal to 90:
3r+4+8r-2=90
Combine like terms:
11r+2=90
Subtract 2 to 90:
11r=88
Divide 11 to both sides:
r=8

Answer:

Option B

Step-by-step explanation:

Let 'x' represents the number of miles traveled and 'y' represents the total cost of of the taxi ride.

Cost of ride with a rate of $2.25 per mile = $2.25x

Since, service charge of the taxi = $3 for first mile

Total cost of the ride = 2.25x + 3

Equation for the cost of the ride will be,

y = 2.25x + 3

Since, farthest distance that the taxi can travel = 35 miles

That means value of x may vary between x = 0 to x = 35 (including x = 25)

Therefore, domain for the situation will be,

0 < x ≤ 35

Option B will be the answer.

find the surface area of the triangular prism

Answers

Answer:

608 ft²

Step-by-step explanation:

1) Find the area of the bases

[tex]A=\frac{1}{2} bh[/tex] where b is the base length and h is the height

Plug in b and h

[tex]A=\frac{1}{2} (12)(8)\\A=48[/tex]

Multiply the answer by 2 (because there are 2 bases)

A=96

Therefore, the area of the two bases is 96 ft².

2) Find the area of the two sides facing up

[tex]A=lw[/tex] where l is the length and w is the width

Plug in l and w

[tex]A=10*16\\A=160[/tex]

Multiply the answer by 2 (because there are 2 sides)

A=320

Therefore, the area of these two sides is 320 ft².

3) Find the area of the bottom side

[tex]A=lw[/tex] where l is the length and w is the width

Plug in l and w

[tex]A=12*16\\A=192[/tex]

Therefore, the area of this side is 192 ft².

4) Add all the areas together

96 ft² + 320 ft² + 192 ft²

= 608 ft²

Therefore, the surface area of the triangular prism is 608 ft².

I hope this helps!

Answer:

608

Step-by-step explanation:

first off you have to find the area of the base

the base is 16 by 12 feet.

so you multiply them and you get

16*12=192 you will have to come back later for this number

next, you find the two outsides of the triangular prism.

they are 10 by 16

10*16=160 and there are two of them so you double it and get 320

now save the 320 too with the 192

now we are going to find the triangles

the formula for an area of a triangle is A=1/2h*w

so we plug in the height which is 8 and the width which is 12

A=1/2(8)*(12)

Simplify

A=48 once again there are two of them so we double it to make it 96

now take all your saved numbers and add them all up

96+320+192

this should give you an answer of 608

hope this helps! have a nice day:)
