The drawing of a building, shown below, has a scale of 2 inches to 8.5 feet.
What is the actual height, in feet, of the house?
Answer:
36 1/8 feet
Step-by-step explanation:
x = height of house in feet
2"/8.5' = 8/5"/x
cross-multiply:
2x = 72.25
x = 36.125 or 36 1/8

Christina is making a necklace using beads. She has 20 red, 14 blue, 10 purple, 28 green, and 8 yellow beads. She randomly chooses a bead to start the necklace. What is the probability of Christina choosing a bead that is not green?
Answer: 13/20
Step-by-step explanation:
Total number of beads: 20+14+10+28+8=80
Green beads out of the total 80: 28
Non-green beads out of the total 80: 80-28=52
The probability of Christina choosing a bead that is not green is the number if non-green beads divided by the total number of beads, so 52/80, which simplifies to 13/20
The probability of Christina choosing a bead that is not green is the number if non-green beads divided by the total number of beads is 13/20.
What is the probability?It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Total number of beads
=20+14+10+28+8
=80
Green beads out of the total 80: 28
Non-green beads out of the total 80:
=80-28
=52
The probability of Christina choosing a bead that is not green is the number if non-green beads divided by the total number of beads, so 52/80, which simplifies to 13/20.

2x−y=5
Answer:
x + 2y = -2
Step-by-step explanation:
Well let's examine the relation between x and y in a perpendicular line.
We can use the fact that for a line Ax + By = C, any line with equation Bx + (-A)y = D is perpendicular (swapping A and B gives a mirror image with respect to the line x=y and changing one of the signs gives a mirror image with respect to axis x or y. Those two together give a perpendicular line).
So we're looking for a line with equation x + 2y = D
We know what it passes through the point (6, -4), so let's input it into the equation x + 2y = D
6 + 2*(-4) = D
6 - 8 = D
D = -2
So the equation is x + 2y = -2
note that 2x + 4y = -4
or any other multiple also works.

Answer:
C.
Step-by-step explanation:
A and D are incorrect because there is one outlier in the lower graph, and there are no signs of clusters on the graph, making B wrong as well. This leaves the only answer, C, which makes sense because there is a positive correlation of a line.

What is the measure of ∡U in the figure shown? ∘
Answer:
∠ U = 70°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the circle , then
∠ U + 50° = 120° ( subtract 50° from both sides )
∠ U = 70°

B. y = -(x - 5)2 - 4
C. y = -(x - 5)2 + 4
D. y = -(x + 5)2 + 4
Answer:
D
Step-by-step explanation:
Because the x-coordinate of the vertex is negative, only A or D could be the correct equation for this parabola. D is correct because its constant (4) matches the y-coordinate of the vertex (-5, 4).

Answer:
D. The probability of selecting an orange is ³/₅.
Step-by-step explanation:
A is incorrect because there would be 4 apples combined (3 from bag one, 1 from bag two). That makes the chance of selecting an apple 2/5 (40%), not 3/10 (30%).
B & C are incorrect because 4/10 (40%) is less than 6/10 (60%)
That leaves D, which state that you have a 60% (3/5) chance selecting an orange, as our answer. That is correct as 3/5 = 6/10 = 60%.
