Given that the two triangles shown below are similar, find the value of x
3
40°
60°
6

Answer:

[tex]x=9[/tex]

Step-by-step explanation:

[tex]\frac{x}{24}=\frac{3}{8}[/tex]

Multiply both sides by 24:

[tex]\frac{24x}{24}=\frac{3\times24}{8}[/tex]

[tex]x=\frac{72}{8}[/tex]

[tex]x=9[/tex]

Step-by-step explanation:

if the decimal is below 5 then round down

Answer:

88

Step-by-step explanation:

2 is less than 5, therefor it would be rounded to 88. If a number higher than five or five was in two's place it would be rounded to 89.

Answer:

3,6,9,12,etc

Step-by-step explanation:

In math, a multiple is the product of any quantity and an integer. In other words, for the quantities a and b, we say that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer. 

Answer:

(1, 28 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]

here (x₁, y₁ ) = G(- 2, 46) and (x₂, y₂ ) = L(4, 10), thus

midpoint = ([tex]\frac{-2+4}{2}[/tex] , [tex]\frac{46+10}{2}[/tex] ) = ([tex]\frac{2}{2}[/tex] , [tex]\frac{56}2}[/tex] ) = (1, 28 )

Answer:

6

Step-by-step explanation:

|-10+4| = |-6|= 6

inside the | | the equation is done normally. that's why it has a negative at first. then, once getting rid of the bars, you change the number to a positive

Answer:

[tex]\boxed {\tt b(-10)=6}[/tex]

Step-by-step explanation:

We are given the function:

[tex]b(x)= \mid x+4 \mid[/tex]

We want to find b(-10). Therefore, we must plug -10 in for each x.

[tex]b(-10)= \mid -10+4 \mid[/tex]

Solve inside of the absolute value symbol. Add 4 to -10 ⇒ -10+4= -6

[tex]b(-10)= \mid -6 \mid[/tex]

Absolute value represents how far away a number is from 0. It is always positive.

-6 is 6 away from 0. Therefore, the absolute value of -6 is 6.

[tex]b(-10)= 6[/tex]

b(-10) is equal to 6.

Answer:

-6/7

Step-by-step explanation:

since both fractions have a common denominator (bottom part of fraction) you would end up subtracting 4-10 which would give you a -6. the denominator stays 7 so you end up with -6/7

Step-by-step explanation:

1000 mL = 1 L

10 mL = 1/1000 × 10 = 0.01 L/sec

60 sec = 1 min

1 sec = 1/60 min

0.01 L/sec

= 0.01 L × 60

= 0.6 L/min

10 mL/sec = 0.6 L/min

Answer:

  (-1, 3)

Step-by-step explanation:

Only the first question is complete.

You want to solve ...

  2x +y = 1

  3x -y = -6

You can add these two equations to get ...

  5x = -5

  x = -1 . . . . . divide by 5

This matches the first choice: (-1, 3).

Answer:

A: (-1,3) is the correct answer to the problem.

Step-by-step explanation:

I just did the a quiz with that question and A is the answer.

Answer:

a= d-r +c

Step-by-step explanation:

a-c = d-r

+c

a= d-r +c

Solving for a gives the result as  a = d - r + c

A variable is something which can vary from a given set of numerical values.We can also substitute some specific values to  a variable.

A constant on the other hand is a fix value even if it is denoted by some letter it is a fixed numerical value that can not be changed.

According to the given question

a is the indicated variable.

Given a - c = d - r

               a = d - r + c

moving any constant or variable from one side to another changes the sign of the constant or the variable.

Answer:

if there was a 15% discount, then you paid 75% of the original price. Since we don't know the orginal price, we will assign it the variable x. Change 75% to a decimal. The equation would be:

.75x = 208.25 To get the variable by itself, divide each side by .75

.75x/.75= 208.25/.75

x = 277.6

The original price of the suit was $277.6

Answer:

40%

Step-by-step explanation:

10 minutes late would mean 18 minutes late on the graph. The graph goes from 10-30 which creates a difference of 20. 8 divided by 20 equals 40 percent.

40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

Given that,

Oliver is typically 10–30 minutes late for his shift at work.

The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.

John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late.

We have to determine,

What percentage of the time does Oliver arrive within 10 minutes of John's arrival time?

According to the question,

Oliver is typically 10–30 minutes late for his shift at work.

John and Oliver are working a shift that starts at the same time.

John always arrives 8 minutes late.

From the complete information, the probability distribution will be:

[tex]= \dfrac{1}{b-a}\\\\= \dfrac{1}{30-10}\\\\= \dfrac{1}{20}[/tex]

Here, John always arrives 8 minutes late.

Therefore,

The percentage of the time that Oliver arrives within 10 minutes of John's arrival time is,

[tex]\rm = 8 \times \dfrac{1}{20}\\\\= \dfrac{2}{5}\\\\= 0.4 \times 100 \\\\= 40 \ Percent[/tex]

Hence, 40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

Answer:c.exactly 18% of students chose blue as their favorite color. I think

Step-by-step explanation:

Answer:

Step-by-step explanation:

If we let A, C, and J represent the number of stickers collected by Ann, Clair, and Josh. respectively, then we have the relations ...

  A = J +7

  J = 2C

  A + C + J = 157

__

Substituting the first equation into the last, we have ...

  J +7 + C + J = 157

  C +2J = 150 . . . . . . . collect terms, subtract 7

Substituting the second equation into this one, we have ...

  C +2(2C) = 150

  C = 150/5 = 30 . . . .  divide by the coefficient of C

  J = 2·30 = 60

  A = 60 +7 = 67

Ann collected 67 stickers, Clair collected 30, and Josh collected 60 stickers.

Answer:

Ann has 67

Josh has 60

Claire has 30

Answer:

d = 5.71

Step-by-step explanation:

Let

Quantity of DVD movies = d

Quantity of Video games = r

Price of DVD movies = $3.50

Price of video games = $2.50

Total budget plan for DVD movies= $20

Which of these represents the possible number of DVDs that could be rented for no more that $20

Price of DVD movies × Quantity of DVD movies = $20

$3.50 × d = $20

3.50d = 20

Divide both sides by 3.50

d = 20/3.50

= 5.71
