Answer K= 20/x
Step-by-step explanation:
The value of k in the given linear equation is 20.
What is a linear equation?A linear equation is an equation where the variable (or variables) has the highest power of one.
Given,
310 - (30 × 7)=5 × k
⇒ 310 - 210 = 5k
⇒ 5k = 100
⇒ k = 100/5 = 20

What mistake did Andy make ?
Answer:
The mistake that Andy made was on step 2 when he multiplied only the variables by 12.
Step-by-step explanation:
When you're solving an equation and are multiplying one side by a number, you need to multiply the other side by that number as well to keep the equation true. Since Andy multiplied only the variables and not the constants on each side of the equation, that means the equation would no longer be valid, and solving it would provide a wrong answer.
Answer:
person above me is right. that's is the answer.

Find the area of this figure
Answer:
216 in2
Step-by-step explanation:
the area of the rectangle is
20(12)=240
area of the triangle is
4(6)= 24
so now we subtract, 240-24= 216 in2
Answer:
228
Step-by-step explanation:
12x8=96 (times 2= 192)
20-(8+8 or 16)=4
4x12=48
------------------------------
6x4=24 (divided by 2 because it is a triangle=12)
48-12=36
------------------------------
192+36=228

Answer:
tan R = 45/28 where ∡R=58.11° and tan S = 28/45 where ∡S=38.48°
Step-by-step explanation:
The tangent of a right triangle's angle is equal to the ratio between the triangle's opposite side to its adjacent side.
tan R = 45/28
R = tan^-1(45/28)
R = 58.11°
tan S = 28/45
S = tan^-1(28/45)
S = 38.48°

Billy bought 25 spinners. Some were $10 and
some were $15. If he spent $295, then how
many of each type did he purchase?
what grade u in ?! i will help u
Billy purchased 9 types of one type and 16 types of another spinner.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
Billy bought 25 spinners.
Let x and y are the type of spinners.
Then, x + y = 25 {equation 1}
Some were $10 and some were $15.
10x + 15y = 295
Simplifying,
2x + 3y = 59 {equation 2}
Multiplying 2 to the equation 1 and subtraction the equation 2,
-y = -9
y = 9
And x = 16
Therefore, each type of spinner is 9 and 16.

The volume V (in cubic feet) of a right cylinder with a height of 6 feet and radius r (in feet) is given by V=6πr2 . Solve the formula for r . Then find the radius of the cylinder when the volume is 1206 cubic feet. Round your answer to the whole number.
Answer:
a) r = √V/6π
b) r = 8 inches
Step-by-step explanation:
a) The volume V (in cubic feet) of a right cylinder with a height of 6 feet and radius r (in feet) is given by V=6πr2 . Solve the formula for r .
Solving for r means making r the subject of the formula
= V=6πr²
Divide both side by 6π
V/6π = 6πr²/6π
r² = V/6π
r = √V/6π
b) Then find the radius of the cylinder when the volume is 1206 cubic feet. Round your answer to the whole number.
r = √V/6π
V = 1206 ft³
r = √1206/6π
r = √(63.98028712294193)
r = 7.9987678503 inches
Approximately r = 8 inches

Suppose that many large samples are taken from a population, and the
sample proportions center around 0.58. Which of the following is most likely
to be the population parameter?
O A. 0.68
OB. 0.58
O C. 0.78
O D. 0.48
Answer:
A- 0.68
Step-by-step explanation:
0.58 is most likely to be the population parameter, since the sample proportions center around this value.
Option B is the correct answer.
We have,
When many large samples are taken from a population, the sample proportions should converge to the population proportion.
If the sample proportions center around a certain value, that value is likely to be a good estimate of the population proportion.
In this case,
Since the sample proportions center around 0.58, it is likely that the population proportion is also around 0.58.
Therefore,
0.58 is the most likely population parameter.

HELPPP MEE PEOPLE PLSSS NO BOTS OR I WILL REPORT BUT PLEASEEE HELPPP MEEE Find the point-slope equation of the line using the point (7,4) and slope of 3/2
Use the slash key ( / ) to indicate a fraction.
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
If this line is given to have a slope of 3/2, let us at least put it in standard form, substituting the point ( 7, 4 ) into the equation afterwards:
y = 3/2* x + b, provided b ⇒ y - intercept,
( 4 ) = 3/2 * ( 7 ) + b,
4 = 21/2 + b,
b = 4 - 10.5,
b = -6.5
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
Answer:
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5

A drawer contains 18 socks: 5 red socks, 10 white socks, and 3 blue socks. Without looking you draw out a sock, what is the probability of NOT getting a red sock?
Answer:
13/18 which is 72.22% chance of NOT getting a red sock
Step-by-step explanation:
As there are 18 total socks, and 13 of them are NOT red, you have a 13 out of 18 chance, or 13/18, or NOT drawing a red sock. This can be converted to the decimal, 0.7222, or percentage of 0.7222 * 100 = 72.22%
