Find the value of each variable. Round to the nearest tenth. How does the measure of angle x compare to the measure of angle z? Justify.
Answer:
z = 47.2°
w = 42.8°
y = 42.8°
x = 47.2°
Step-by-step explanation:
found altitude ('h') first: 6/h = h/7; h = [tex]\sqrt{42}[/tex]
found base by using Pythagorean Theorem:
7² + ([tex]\sqrt{42}[/tex])² = c²
c = [tex]\sqrt{91}[/tex]
found angle z using Rule of Sines:
sin 90 / [tex]\sqrt{91}[/tex] = sin z / 7
arcsin z = 7 / [tex]\sqrt{91}[/tex] = 47.2°
found angle w by adding 90 and 47.2, then subtracting from 180 to get 42.8°
found angle y by subtracting m∡z from 90° to get 42.8°
found angle x by adding 90 and 42.8°, then subtracting from 180

[tex]\frac{1}{2} |x_{1} (y_{2} -y_{3}) + x_{2} (y_{3} -y_{1} ) + x_{3} (y_{1}- y_{2} ) |\\= \frac{1}{2} \times |5(4-5) + 8 (5-2) + 4(2-4) |\\=\frac{1}{2} \times |-5 +24 + -8 |\\=\frac{1}{2} \times 11\\= 5.5[/tex]
Find the area of the parallelogram by composing into rectangles or decomposing into triangles or other shapes as needed. 8 yd 6 yd 15 yd
10 yd
Answer:
Below.
Step-by-step explanation:
The area = area of a rectangle on the same base and between the same parallel lines
= (15 + 6) * 8
= 21 * 8
= 168 yd^2.
Answer:
160
Step-by-step explanation:
First, you add 15 + 6 multiplied by 8.
Expression (15 + 6) x 8=?
First, add the expression in the prentice.
15 + 6= 21
Cut out the 10. Why? Because it says make it a triangle. If u did it the other
way it wouldn't make sense.
then multiply 21 and 8
that gives you 160

You pay $3 per square foot for carpeting. Which equation can be solved to find the
amount you will pay to cover a triangular section of the floor with a base of 2 yards and
a height of 5 yards?
Answer:
$135
Step-by-step explanation:
Step 1
Conversion
Base = 2 yards
1 yard = 3 feet
2 yards = x
Cross Multiply
x = 2 × 3 feet = 6 feet
Height = 5 yards
1 yard = 3 feet
5 yards = x
Cross Multiply
x = 5 × 3 feet = 15 feet
Step 2
Find the area of the triangle
Area of a triangle = 1/2 × base × height
Base = 6 feet
Height = 15 feet
Area = 1/2 × 6 × 15
= 45 square feet
Step 3
Find the cost of the carpet
1 Square foot = $3
45 square feet = x
Cross Multiply
x = 45 × $3
x = $135
Therefore, the amount you will pay to cover a triangular section of the floor is $135

Over 5 days, Kimberly sheared 300 sheep. How many would she be able to shear in 26 days?
What was her rate per day?
Answer:
Kim shears 1560 sheep in 26 days.
Her rate per day is 60.
Step-by-step explanation:
For 26 days:
[tex]\frac{5}{300} =\frac{26}{x} \\\\5x=7800\\x=1560[/tex]
For per day:
[tex]\frac{5}{300} =\frac{1}{x} \\\\5x=300\\x=60[/tex]
A quadrilateral in the coordinate plane has vertices (3, 2), (3,-4), (5,4), and (5,-2). What is the area, in square units, of the quadrilateral?
Answer:
4 square units
Step-by-step explanation:
the distance between (3, -4) and (5, -4) is 2, and the distance between (3, -2) and (5, -2) is also 2. since its a quadrilateral do 2x2 and you get 4.

Solve the equation 18 = 3 + 5x for x.
Answer:
[tex]18 = 3 + 5x \\ 5x = 18 - 3 \\ 5x = 15 \\ x = 3[/tex]
Answer:
X = 3
Step-by-step explanation:
18 - 3 = 15 and 3 x 5 = 15. However there is a way to check which would be doing 5 x 1 + 3 and 5 x 2 + 3 and so on and so on until you find your answer.

Autumn has 6 ribbons for her hair. Each ribbon is 3 feet long. How many total inches of ribbon
does Autumn have?
Answer:
she has a total of 216 inches of ribbon
Step-by-step explanation:
1 foot is equal to 12 inches.
if she has 3 feet per ribbon, and each foot is 12 inches, then 3 × 12 would be 36, making each ribbon 36 inches.
But, she has 6 pieces of ribbon, so that's 36 inches 6 times. 6 × 36 is 216, so she has a total of 216 inches of ribbon.
There are two numbers and the first is larger than the second. Three times
the larger number plus the smaller number is forty. Twice the smaller number
plus one is equal to the larger number. Find both numbers
Answer:
3y+x=40
x=40-3y..........1
2x+1=y........2
subst. 2into1:
x=40-3(2x+1)
x=40-6x-3
7x=37
x=37/7
subst.x into2:
2(37/7)+1=y
y=81/7
Last year, 85% of students participated in the school fundraiser. Using this data, what would be the BEST prediction of how many of the 320 students will participate in the fundraiser this year?
Answer:
C. 272
Step-by-step explanation:
Since we know 85% of the students participated last year we can assume the same amount will participate this year so to find the answer you simply do the total number of students (320) multiplied by 85% or .85 to get the best guess of how many students will participate this year.
