Mason built a model of a birdhouse for his engineering class,as pictured below.10 in,14 in,8 in,8 in.Find the area of Mason's birdhouse.
Answer:
672 square inches
Step-by-step explanation:
i took the test and got this question right
The area of Mason's birdhouse is 664 square inches.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
For the area of Mason's birdhouse,
We need to calculate the surface area of all the sides and add them up.
Now,
The birdhouse has six sides.
= a top, bottom, front, back, left, and right side.
The top and bottom of the birdhouse are both rectangles with dimensions 10 inches by 8 inches.
So,
The area of each rectangle.
= 10 in × 8 in
= 80 square inches
So,
The total area of the top and bottom of the birdhouse.
= 2 × 80 square inches
= 160 square inches
Now,
The front and back of the birdhouse are both rectangles with dimensions 10 inches by 14 inches.
The area of each rectangle.
= 10 in × 14 in
= 140 square inches
The total area of the front and back of the birdhouse.
= 2 × 140 square inches
= 280 square inches
Now,
The left and right sides of the birdhouse are both rectangles with dimensions 8 inches by 14 inches.
The area of each rectangle.
= 8 in × 14 in
= 112 square inches
The total area of the left and right sides of the birdhouse.
= 2 × 112 square inches
= 224 square inches
Now,
The total surface area of Mason's birdhouse.
= 160 + 280 + 224
= 664 square inches.
Thus,
The area of Mason's birdhouse is 664 square inches.

1) Let X represent the number of tires with low air pressure on a randomly chosen car. The probability of distribution of X is as follows:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) =
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
c) P (all 4 tires) =
d) Compute the expected number of tires with low air pressure.
e) Compute the standard deviation for the number of tires with low air pressure.
Answer:
0.2 ; 0.3 ; 0.1 ; 2
Step-by-step explanation:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) :
From probability distribution table Given :
P(1) = 0.2
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
P(x > 2) = p(3) + p(4)
P(x > 2) = 0.2 + 0.1 = 0.3
c) P (all 4 tires)
From the table :
P(x = 4) = 0.1
d) Compute the expected number of tires with low air pressure.
E(X) = Σx * p(x)
E(x) = (0*0.1) + (1*0.2) + (2*0.4) + (3*0.2) + (4*0.1) = 2

An angle measuring 28.3 radians is drawn in standard position?
In what quadrant will the terminal side of this angle lie?
Express your answer as a Roman numeral.
Answer:
The terminal side of angle will lie in thirds quadrant
Step-by-step explanation:
Given the angle is 28.3 degree radians
Converting it into degrees we get -
28.3rad × 180/π = 1621.471°
Total 360 degrees rotation in this angle
1621.471°/360 = 4
SO the remaining degrees 181.471
The angle grater than 180 lies in third quadrant.
The terminal side of angle will lie in thirds quadrant

A tire on a vehicle has a diameter of 30in. As it moves down the
road it makes 50 full revolution. What is the approximate distance
it traveled?
Answer:
94.25 in
Step-by-step explanation:
In one revolution, the tire moves a distance equal to its circumference. If the diameter is 30 in, the radius is half of that, 15 in. Circumference is 2 pi times the radius:
[tex]C=2\pi r= 2\pi (15) = 30\pi \approx 94.25 \text{ in.}[/tex]

The m<3 = (2x + 10) and m<6 = (3x-15) find the value of x, m<3 and M<6
9514 1404 393
Answer:
x = 25; ∠3 = ∠6 = 60°
Step-by-step explanation:
Angles 3 and 6 are alternate interior angles, so are congruent.
2x +10 = 3x -15
25 = x . . . . . . . . . . . add 15-2x
2x +10 = 2(25) +10 = 60
The measures of angles 3 and 6 are 60°.

Find the measure of angle A.
can you show me how to do this problem
Answer:
x = 25/2
Step-by-step explanation:
We may apply the property of triangles that says the three angles must add up to 180 degrees. Therefore:
x + 4 + x + 61 + 90 = 180
2x + 65 = 90, or
2x = 25, and so x = 25/2
pls help question in the pic

Answer:
Number 7 is 25%
Step-by-step explanation:
You take the original price and subtract it by each percentage until you get 30.
$40.00 - 15% = 34
$40.00 - 20% = 32
$40.00 - 40% = 24
$40.00 - 25% = 30
Therefore, the answer is 25% !

On Eduardo's workbench are the following
paint cans.
• 3 cans of red paint
• 5 cans of blue paint
• 8 cans of green paint
• 4 cans of yellow paint
Eduardo will randomly choose one can of
paint. What is the probability that he will
choose a can of red paint or a can of blue
paint? (71A, 7.1B, 7.1F)
Answer: 2/5
Step-by-step explanation:
Number of cans of red paint = 3
Number of cans of blue paint = 5
Number of cans of green paint = 8
Number of cans of yellow paint = 4
Total number of cans of paint = 20
The probability that Eduardo will
choose a can of red paint or a can of blue will be:
= P(red) + P(blue)
= 3/20 + 5/20
= 8/20
= 2/5
The probability is 2/5.
