Answer:
<A = 56degrees
<B = 34degrees
<C = 56degrees
Step-by-step explanation:
From tyhe diagram, the sum of m<C and m<D is 180degrees. Hence;
<C + <D = 180
<C + 124 = 180
<C = 180 - 124
<C = 56degrees
Also;
<B + 90 + <C = 180
<B + 90 + 56 = 180
<B + 146 = 180
<B = 180 - 146
<B = 34degrees
Similarly;
<A + <B = 90
<A + 34 = 90
<A = 90 - 34
<A = 56degrees

Answer:
shen's new area will be 1200 ft ^ 2
It will be 2 times the original
Donna should increase the length by 5 times
Step-by-step explanation:
Original length = 40
New length = 30 x 4 = 120
Original width = 20
New width = 20 x 5 = 100
120 x 100 = 12000 ft^2
12000/600 = 20
It will be 20 times larger
For Donna:
ex:
length = 1
width = 2
Area = 2
He wants it to be 15 times 2
Lisa says increase 4 times
2 x 3 = 6
30/6 = 5

Good Luck!
Step-by-step explanation:
You would add 16 to both side in the attempt of completing the square
Step 1: Move any constant number (this case, it's 35) to the other side
Step 2: You will have a format of ax2 + bx = c, where your a = 1, b = 8, and c = 35
*a must always be 1*
Step 3: Divide b by 2 and then square that number. Your b = 8, so 8/2 is 4. Squaring 4 gives you 16.
Hence, that's why you add 16 to both side from your question.

Solutions to a quadratic equation are -7 and 1. What is the equation of its axis of symmetry?
Answer:
Axis of symmetry: x=-4
Step-by-step explanation:
If x=-7 and x=-1 are solutions to a quadratic equation, then that quadratic equation must be (x+1)(x+7)=0 -> x^2+8x+7=0 as both solutions satisfy the Zero Product Property where the function is f(x)=x^2+8x+7. The axis of symmetry would be the line x=-b/2a which means the axis of symmetry is x=-(8)/2(1)=-8/2=-4 -> x=-4. It can also be found by turning f(x)=x^2+8x+7 into f(x)=(x+4)^2-9 by completing the square, and since h=-4, then the axis of symmetry would be x=h=-4. Refer to the graph.

A high school basketball coach is selecting his team. The minimum and maximum height requirements are as follows:
Point Guard: Small Forward: Center:
6’2" – 6’6" tall at least 6’6" tall at least 6’8" tall
The heights of the Lincoln High School boys have a normal distribution with a mean height of 70 inches and the standard deviation of 4 inches.
Which statement is true?
A. About 16% of the boys are eligible to be a point guard on the team. B. About 2% of the boys are eligible to be a small forward on the team. C. About 48% of the boys are eligible to be a small forward on the team. D. About 34% of the boys are eligible to be a point guard on the team.
Answer:
B. About 2% of the boys are eligible to be a small forward on the team
Step-by-step explanation:
Recall : 1 feets = 12 inches
Point guard = 6’2" – 6’6" tall = 74 - 78 inches
Mean = 70 ; Standard deviation = 4
Z = (x - mean) / standard
P(x < 74) = (74 - 70) / 4 = 1
P(x < 78) = (78 - 70) / 4 = 2
0.97725 - 0.84134 = 0.13591
Small forward : 6'6" = 78 inches
P(x ≥ 78) = (78 - 70) / 4 = 2
P(z ≥ 2) = 0.02275 = 2.275% about 2%
Centre : 6'8" = 80
P(x ≥ 80) = (80 - 70) / 4 = 2.5
P(z ≥ 2.5) = 0.0062097 = 0.62%
About 2% of the boys are eligible to be a small forward on the team. Then the correct option is B.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
A high school basketball coach is selecting his team.
The minimum and maximum height requirements are as follows:

The value of the z-score will be
[tex]z = \dfrac{x - \mu }{\sigma}[/tex]

Three boys were playing balls. Ben's ball bounced eight more times than Menard's . Menard's ball bounced half as many times as Diego's. Diego's ball bounced eight times. How many times did Ben's ball bounced?
Answer:
12 bounce
Step-by-step explanation:
Let :
Number of Menard's bounce = x
Ben's bounce = x + 8
Diego's bounce = 2x
If Diego's bounce = 8
Then ;
2x = 8
x = 8/2
x = 4
Ben's bounce = x + 8
Ben's bounce = 4 + 8 = 12

the answer is
y≥2x/5+2
Step-by-step explanation:
we moved the y to the right site and the -10 to the left site
so we had
2x+10≤5y
and then we devided by 5
2x/5+10/5≤y
y≥2x/5+2
hopefully its correct
Answer: Choice D
[tex]y \ge \frac{2}{5}x +2\\\\[/tex]
=======================================
Work Shown:
[tex]2x - 5y \le -10\\\\-5y \le -2x-10\\\\y \ge \frac{-2x-10}{-5} \ \text{ ... see note1 below}\\\\y \ge \frac{-2x}{-5} - \frac{10}{-5}\\\\y \ge \frac{2}{5}x +2 \ \text{ ... answer is choice D}\\\\[/tex]
Note1: when dividing both sides by a negative number, the inequality sign flips.
----------------
Here's another approach that doesn't involve dividing both sides by a negative number.
[tex]2x - 5y \le -10\\\\2x \le -10+5y\\\\2x +10\le 5y\\\\5y \ge 2x+10 \ \text{ .... see note2 below}\\\\y \ge \frac{2x+10}{5}\\\\y \ge \frac{2x}{5} + \frac{10}{5}\\\\y \ge \frac{2}{5}x +2\\\\[/tex]
Note2: I swapped the left and right sides. Doing this swap means that the inequality sign must flip as well.

A trapezoid has an area of 140 square centimeters with bases of 12 and 10 centimeters. What is the length of the height? Round to the nearest tenth place.
Answer:
12.7 cm
Step-by-step explanation:
Area of a trapezium = 1/2 x ( a + b) x height
a and b represents the bases
140 = 1/2 x (12 + 10) x h
140 = 11h
h = 140 / 11
h = 12.727 cm
h = 12.7 cm to the nearest tenth
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
