Answer:
x = 128
Step-by-step explanation:
Right angles are 90 degrees. 90 + 90 + 52 = 232. 360 (angles in a quadrilateral) - 232 = 128.
Answer:
ans is 128
Step-by-step explanation:
90+90+52+x=360(all sides of triangle is 360)
180+52+x=360
232+x=360
x=360_232
x=128

Klay's lunch cost $6. This is $2 less than Ella's lunch cost. How much did
Ella's lunch cost? Select the correct solution method, using x to represent the
cost of Ella's lunch.
A.
NIX
= 6. Multiply both sides by 2. Ella's lunch cost $12.
B. 2x = 6. Divide both sides by 2. Ella's lunch cost $3.
C. x + 2 = 6. Subtract 2 from both sides. Ella's lunch cost $4.
O D. X-2 = 6. Add 2 to both sides. Ella's lunch cost $8.
Answer:
D
Step-by-step explanation:
Because it says Klay lunch cost is $2 less than Ella's.
==> Ella's - $2 = Klay's
==> x-2=6
plus both side by 2
so the answer is $8

X=

Answer:
x ≈ 17.14
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{12}{x}[/tex] ( multiply both sides by x )
x × tan35° = 12 ( divide both sides by tan35° )
x = [tex]\frac{12}{tan35}[/tex] ≈ 17.14 ( to the nearest tenth )
eight times the reciprocal of a number equals 4 times the reciprocal of 2. find the number
Answer:
The number is 4
Step-by-step explanation:
Let the number = 'x'
Reciprocal of 'x' = 1/x
Reciprocal of 2 = 1/2
8 times the reciprocal of 'x' = [tex]8*\frac{1}{x}\\[/tex]
[tex]8*\frac{1}{x}= 4* \frac{1}{2}\\\\8*\frac{1}{x}= 2\\[/tex]
Now multiply both sides by x
[tex]8*\frac{1}{x}*x = 2*x\\\\8 = 2x[/tex]
Now divide both sides by 2
[tex]\frac{8}{2}=\frac{2x}{2}\\\\4 = x[/tex]
x = 4

Answer:
LQ: 7.5
UQ: 21
Step-by-step explanation:
After identifying the median, remove it and split the data into two halves.
The upper quartile is the median is the top set of data and the lower quartile is the median is the bottom set of data.
If you have two numbers in the middle, you add them and divide by two to find the median/ quartile
so
[tex]\frac{7+8}{2} =7.5[/tex]
[tex]\frac{21+21}{2} =21[/tex]

In AFGH, FG – HF and mZF = 56°. Find m_H.
Answer:
m<H = 62°
Step-by-step explanation:
If FG is congruent to HF, it means their opposite angles are also congruent to each other. This implies that, <H = <G. Thus, ∆FGH is an isosceles triangle with base angles <F and <G.
Given that m<F = 56°, therefore:
56° + 2(m<H) = 180° (sum of triangle)
2(m<H) = 180° - 56°
2(m<H) = 124°
m<H = 124/2
m<H = 62°
Find the areas of the figures below. Show all work on for each problem.
Answer:
310 in²
Step-by-step explanation:
Area of the figure = area of the larger rectangle + area of the medium rectangle + area of smaller rectangle
✔️Area of the larger rectangle = L*W
L = 20 in
W = 7 in
Area = 20*7 = 140 in²
✔️Area of the medium rectangle = L*W
L = 20 - 2 = 18 in
W = 22 - (10 + 7) = 5 in
Area = 18*5 = 90 in²
✔️Area of the smaller rectangle = L*W
L = 8 in
W = 10 in
Area = 8*10 = 80 in²
✅Area of the figure = 140 + 90 + 80 = 310 in²

One third is equivalent to what number over 12?
Answer:
4/12
Step-by-step explanation:
1/3=x/12
using the butterfly method you see that
12=3x
and when solved you get
x=4
giving you
4/12
Also multiply 1/3 by 4 on each side
One third is equivalent to 4 over 12.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Let the unknown number be x.
Here, 1/3 = x/12
Multiply both the numerator and denominator of 1/3 by 4, we get
4/12
So, 4/12 = x/12
x=12
Therefore, the unknown number is 12.
