Answer:
∠ 1 = 72°
Step-by-step explanation:
(4n - 2) and (2n + 17) are adjacent angles and sum to 180° , that is
4n - 2 + 2n + 17 = 180
6n + 15 = 180 ( subtract 15 from both sides )
6n = 165 ( divide both sides by 6 )
n = 27.5
Then
2n + 17 = 2(27.5) + 17 = 55 + 17 = 72
∠ 1 and 2n + 17 are vertical angles and congruent , so
∠ 1 = 72°
solve using suitable property -2/3 + 5/7 + -8/9 + 3/14
Answer:
[tex]\dfrac{-79}{126}[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}[/tex]
The LCM of 3,7,9 and 14 is 126
So,
[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}=\dfrac{42(-2)+18(5)+14(-8)+9(3)}{126}\\\\=\dfrac{-79}{126}[/tex]
So, the value of the given expression is equal to [tex]\dfrac{-79}{126}[/tex].
What is 9.85km to 5000m as a ratio in it's lowest terms
Answer:
197:100
Step-by-step explanation:
9.85km in m =9850m
9850:5000
÷10 ÷10
985:500
÷5 ÷5
197:100
as we can’t simplify any more, this must be the lowest term.

Answer:
D 36πa^6b^9
Step-by-step explanation:
Step 1. Write the formula for the volume of a sphere.
V = (4/3)πr³
Step 2. Replace r with the given radius. Since the given radius is an expression, remember to enclose it in parentheses and cube the entire expression.
V = (4/3)π(3a²b³)³
Step 3. Simplify the expression. Start by cubing each factor inside the parentheses.
V = (4/3)π ×(3)³(a²)³(b³)³
To raise an exponent to an exponent, multiply the exponents.
V = (4/3)π × 27a^6b^9
V = (4/3 × 27)πa^6b^9
V = 36πa^6b^9
Answer: D 36πa^6b^9

Find the measures of interior angles. Find a and B.
Answer:
A = 68
B = 44
C = 68
Step-by-step explanation:
find x:
68 + x + x - 24 = 180
2x + 44 = 180
180 - 44 = 136
136 / 2 = 68
x = 68
_________________________
68 + 68 + 44 = 180

Answer:
h = -9
Step-by-step explanation:
2(h + 3.5) = -11
2h + 7 = -11
subtract 7 from both sides of the equation:
2h = -18
divide both sides by 2:
h = -9

what is the theoretical probability that you roll a 3 or 4?
Answer:
3 = 1/6 chance 4 = 1/6 chance
Step-by-step explanation:
BECAUSE there are 6 numbers on a number cube and there is no ganruntee that it will land on 4 or 3 so its a 1/6 chance that it will land on them.
Answer:
1/6
Step-by-step explanation:
A dice (Number cube in this case) has six sides, in only which one side is three and one side is 4.

What is the volume of this entire prism
Answer:
520 cubic centimeters (cm^3)
Step-by-step explanation:
volume = length * width * height
length = 13
width = 5
height = 4 + 4, so height = 8
volume = (13) * (5) * (8)
volume = 520 units
Since the given measurements are in centimeters and the answer is the volume of the prism, the answer must be in cubic centimeters
So, the final answer is 520 cubic centimeters (cm^3)

At the clothing store, 1/8 of the clothes are shirts. Of the shirts 1/4 are green. What fraction of the clothing in the store are green shirts?
Answer:
1/32
Step-by-step explanation:
So we know that green shirts can be represented by 1/4 of 1/8. It's 1/4 of the 1/8 of shirts in the store. The key word here is "of," which means multiplication.
So you can replace 1/4 of 1/8 with:
[tex]\frac{1}{4} x \frac{1}{8}[/tex]
To multiply fractions, it's really simple: multiply the denominator with the denominator and the numerator with the numerator.
[tex]\frac{1}{4} x \frac{1}{8} = \frac{1}{32}[/tex]
So 1/32 of the entire store is green shirts.
