What was Jackie's mistake?
Jackie is asked to find the value of x in the following set of complementary anges.
Answers
Answer:
x=37
Step-by-step explanation:
Complementary angles are a set of 2 angles that when added together, add up to 90. In order to solve for x, both angles have to be added and set to be equal to 90... but Jackie only used one of the angles, not both. The correct equation is: x+16+x=90
Answer:
Jackie forgot to add variable X
Step-by-step explanation:
Jackie Did
X +16= 90
equation :
x+x+16= 90

options are
60% 80%
19% 40%
Answers
Answer:
19%
Step-by-step explanation:
40/50 = x/100
solve for x
x is equal to 20%
but out of the answer choices it's 19%.
Answer: 19%
Step-by-step explanation:
50, percentage decreased by 60% (percent) of its value = 20
50, percentage decreased by 80% (percent) of its value = 10
50, percentage decreased by 19% (percent) of its value = 40.5
50, percentage decreased by 40% (percent) of its value = 30
Hence, the answer is 19%

The floor of a rectangular cage has a length 4 feet greater than its width, w. James
will increase both dimensions of the floor by 2 feet. Which equation represents the
new area, N, of the floor of the cage?
Answers
Answer:
x² + 8x + 12
Step-by-step explanation:
Area of a rectangle = length × width
Original dimensions:
Width = x
Length = x + 4
James will increase both dimensions of the floor by 2 feet
New dimensions:
Width = x + 2
Length = x + 4 + 2
= x + 6
Area of the new rectangle = length × width
= (x + 2) × (x + 6)
= x² + 6x + 2x + 12
= x² + 8x + 12
Equation which represents the
new area, N, of the floor of the cage = x² + 8x + 12

16) Jenna is responsible for changing the broken light bulb in a streetlamp. The streetlamp is 14 feet high. Jenna places the base of her ladder 3 feet from the base of the streetlamp. Jenna can extend the ladder from 10 feet to 14 feet. How long must her ladder be to reach the top of the streetlamp? Will her ladder work?
Answers
Use the Pythagorean theorem:
Height is 14, base is 3, so we can calculate the length required.
Length = sqrt(14^2 + 3^2)
Length = sqrt( 196 + 9)
Length = sqrt(205)
Length = 14.32 feet.
The ladder needs to be 14.32 feet. The longest her ladder can be is 14 feet so her ladder won’t work.

Step-by-step explanation:
The best way to remember the formula is y=mx+b aka (your mom's ex bf)Just by looking at the slope you can automatically tell it's moving by one so in your formula, 'm' is the slope.Add 1x to replace 'm' or you can leave x alone because x is already one, your choice.b is the indication on where your slope started in the y-axis. In this case, by looking at the y-axis on the graph, the slope starts at 8 so that will be your b.Therefore, your answer is y=1x+8what is 4.13 to the nearest tenth

Find the value of x and y of the equilateral triangle
Answers
Answer:
x = 12
y = 30
Step-by-step explanation:
We know:
All sides of equilateral triangle are equal:
= > 3 x + 8 = 4 x - 4
= > 8 + 4 = 4 x - 3 x
= > x = 12
Also, we know all angles of equilateral triangle is 60. And their sum is 180.
= > 2 y = 60
= > y = 30
Hence we get required answer!
Find the measures of the exterior angles of the polygon.
Answers
Answer:
D : 125°,125°,55°,55°
Step-by-step explanation:
Finding the interior angles makes the question easier.
The two base angles for b1 are both 125°, and the two base angles for b2 are both 55°.
Because a straight line is 180°, we can find the exterior angles by subtracting the interior angles from 180°.
180°-55° = 125°
180°-125° = 55°
Round 54, 842 to the nearest hundred.
