Answer:
r = 16
Step-by-step explanation:
Cross multiply:
4 x 20 = r x 5
Simplifying
4 x 20 = r x 5
Multiply 4 x 20
80 = r x 5
Reorder the terms for easier multiplication:
80 = 5r
Solve
80 = 5r
Solve for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-5r' to each side of the equation.
80 + -5r = 5r + -5r
Combine like terms: 5r + -5r = 0
80 + -5r = 0
Add '-80' to each side of the equation.
80 + -80 + -5r = 0 + -80
Combine like terms: 80 + -80 = 0
0 + -5r = 0 + -80
-5r = 0 + -80
Combine like terms: 0 + -80 = -80
-5r = -80
Divide each side by '-5'.
r = 16
Simplify
r = 16

Find the measures of the interior angles of the triangle. A 30° B 40 С
Answer:
A = 110°
Step-by-step explanation:
All triangles have angles that add to a sum of 180°
That means you can simply subtract angle B and C from 180 to get angle A
180 - 30 - 40 = 110°

Lines a and b are parallel. Line c is a transversal. FInd the measures of all angles formed by a, b, and c, given each scenario. One of the angles measures 150 degrees.
Answer:
30° and 150°
Step-by-step explanation:
Given
Parallel lines a and b
Transversal c
Angle = 150°
Required
Determine the list of possible angles
A transversal divides a parallel line into two measure which add up to 180°
Given that one of the angles is 150°, the other angle would be 180° - 150°
Other angle = 180° - 150°
Other angle = 30°
Aside 30° and 150°, there's no other possible angle that can be formed by the given information

Angle M and angle R form a supplementary angle.
The measure of Angle R is 40+2x.
The measure of angle M is 13x.
What is the value of x
Answer:
[tex]x = 9.33(appx)[/tex]

x + 12 = -5
O A. x= -17
B. X= -7
O c. x= 17
O D. x = 7
Answer:
x=-17
Step-by-step explanation:
Original Equation;
x+12=-5
The 12 will cross the equal sign so it will become -12. So it's going to be;
x=-5-12
There are two negative number so you add them and when you add them it would still be negative. And you would have to add them because when there are two negative numbers without any other sign you will have to add so it's going to be;
x=-17
This is the final answer!!!
What is the quotient of Three-fourths and StartFraction 5 Over 6 EndFract
a. Three-fourths
b. StartFraction 9 Over 10 EndFraction
c. 1 1/9
d, 4 1/2
Answer:
the quotient of Three-fourths and StartFraction 5 Over 6 EndFract is [tex]\frac{9}{10}[/tex]
Hence Option B is correct.
Step-by-step explanation:
We need to find quotient of Three-fourths and StartFraction 5 Over 6 EndFract
Writing in mathematical form: [tex]\frac{3}{4} \div \frac{5}{6}[/tex]
Solving, we get
(Converting division sign into multiplication the term is reciprocated so, 5/6 will become 6/5 )
[tex]\frac{3}{4} \div \frac{5}{6}\\=\frac{3}{4} \times \frac{6}{5}\\=\frac{3}{2} \times \frac{3}{5}\\=\frac{9}{10}[/tex]
So, the quotient of Three-fourths and StartFraction 5 Over 6 EndFract is [tex]\frac{9}{10}[/tex]
Hence Option B is correct.

75 – 3.5y – 4y = 4y + 6
y=6
Step-by-step explanation:
[tex]75 - 3.5y - 4y = 4y + 6[/tex]
Collect like terms and simplify
[tex] - 3.5y + 4y - 4y = 6 - 75 \\ - 11.5y = - 69[/tex]
Divide both sides of the equation by-3.5
[tex] \frac{ - 11.5y}{ -11.5} = \frac{ - 69}{ - 11.5} [/tex]
Simplify
[tex]y = 6[/tex]
The value of the y in the given equation is 6.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given that, an equation, 75 - 3.5y - 4y = 4y + 6, we need to find the value of y,
75 - 3.5y - 4y = 4y + 6
Combining the like terms,
75 - 6 = 4y + 4y + 3.5y
69 = 11.5y
y = 6
Hence, the value of the y in the given equation is 6.

Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize. Suppose that Isaac is going to buy 6 boxes of this cereal, and let X represent the number of prizes he wins in these boxes. Assume that these boxes represent a random sample, and assume that prizes are independent between boxes. What is the probability that he wins exactly 2 prizes in the 6 boxes?
Answer: 0.3 on khan academy
Step-by-step explanation: ♂️
The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.
Calculation of the probability:Since Isaac's favorite cereal is running a promotion that says 1-in-4 boxes of the cereal contains a prize this mean
So,
P(box containing prize) = 1/4 = p =0.25
So,
q=1 - p
= 0.75
And total box (n)=6
Let us assume x be number of prize win.
So,
Probability that he will win exactly two prize is
P(X=2)= [tex]\binom {6}{2}(0.25)^2(0.75)^4[/tex]
= 0.2966
=0.30(approx)
hence, The probability that he wins exactly 2 prizes in the 6 boxes is to be considered as the 0.30.
