Answer:

65 miles

Step-by-step explanation:

Answer:

65MPH (or 65 miles)

Step-by-step explanation:

I used a proportion:

487.5MI/7.5HR = ?MI/1HR

(mi/hr = mi/hr)

cross multiply:

487.5 x 1 = 487.5

then divide:

487.5 divided by 7.5 =

65 miles

Answer:

10% interest

Step-by-step explanation:

150,606.59 - 78,170 = 72,436.59

72,436.59 / 9 = 8,048.51

8,048.51 / 78,170 = 0.1029... = 10%

Answer:

90/125*100=9000/125

9000/125=72

72%

Answer:

PB = 1.8

Step-by-step explanation:

PQ = 8 cm, BC = 10 cm and AB = 9 cm

∆ABC is similar to ∆APQ.

Therefore:

[tex] \frac{AB}{AP} = \frac{BC}{PQ} [/tex]

Plug in the values

[tex] \frac{9}{AP} = \frac{10}{8} [/tex]

Cross multiply

AP × 10 = 8 × 9

AP × 10 = 72

Divide both sides by 10

AP = 7.2

PB = AB - AP

PB = 9 - 7.2

PB = 1.8

Answer:

The relation represented by diagram 4 is NOT a function.

Step-by-step explanation:

To tell if a relation is not a function, pay attention to the x-intercepts. If there is more than one y-intercept with the same x-intercept, then it is not a function, because a function can only have one output (y-value) for each input (x-value).

According to the fourth diagram, the domains include 1, 2, and 3 while the range includes A, B, and C. Also, the ordered pairs would go as follows according to the arrows:

(1, A), (2, A), (2, B), (3, C)

While the y-values, A and B, are different, they share the same input, 2. Therefore, the relation represented by the 4th diagram is NOT a function.

Answer:

75% increase

Step-by-step explanation:

First we need to figure out how many new records she got this year...

7-4 = 3 new records.

Now, we need to know how many times 4 goes into 100%....

100 ÷ 4 = 25%

This tells us that a single record this year is a 25% increase.

Now, we multiply 25% by 3 to get 75% as our final answer

Hope this Helps!!! :)

Answer:

7/10ths

Step-by-step explanation:

There are ten blocks all together, which is where the 10 comes from, there is 7 shaded that is where the 7 comes from.

Answer:

The percentage is 70%.

Step-by-step explanation:

There are 10 spaces total, and 7 are shaded in. 7 divided by 10 is 0.7.

0.7 as a percentage is 70%.

So 70% of the block is shaded in.

Answer:

Step-by-step explanation:

Step one.

Read the slope

-1/4

Step two

Put the slope in the general equation

y = mx + b

y = -1/4 x + b

Step 3

Put the point into the equation from step 2

(-8,5)

5 = -1/4  -8   + b

5 = 2 + b                   Subtract 2 from both sides

5-2 = b

b = 3

Step 4

Write the entire equation

y =   -1/4 x + 3

Answer:

x=28

Step-by-step explanation:

-2(3x-9)+5x =-10

now we times -2 to to the inside of the parenthese

giving us

-6x+18 +5x= -10

add like terms

add -6x and 5x

-1x+18=-10

now we add like terms of the constants

minus 18 on  both sides

-1x=-28

now divide by -1

x = 28

Answer:

x = 28

Step-by-step explanation:

First, remove the parentheses by distributing -2.

-6x + 18 + 5x = 10

Next, collect the like terms.

-x + 18 = -10

Next, move the constant to the right-hand side and change its sign.

-x = -10 - 18

Next, calculate the difference

-x = -28

Lastly, change the signs on both sides of the equation.

x = 28

These are the steps to answer this equation.

Step-by-step explanation:

every ratio is been multiplied for eleven si if we know this we can tell that

1 times 11= 11

Answer:

11

Step-by-step explanation:

Just times the things by 11, 5 times 11 is 55, 10 times 11 is 110, and 20 times 11 is 220, so 1 times 11 is 11 so 11 is the answer.

Answer:

Given - A rectangle whose area is 1 2/5 m^2

- length is 4/5 m

To find - Length of rectangle

Solution -

1 2/5 = 7/5 m^2

Let the length be X

Area of rectangle= Length × Breadth

7/5 = X × 4/5

7/5 × 5/4 = X

7/4 = X

Length of rectangle= 7/4

ANSWER IS 15x20 Please make meh brainlist

Answer:

X = -5

Step-by-step explanation:

3x - 15 = -30       You want to isolate tha variable

3x= -30+15    Add 15 to -15 in order to get rid of it. All you do to one side you do to the other, so you add 15 to 30

3x= -15    

x= -15÷3   Divide x by 3 in order to get rid of the 3. Do it to the other side

x=-5

Answer:

The student had a total of 25 questions on his test.

Step-by-step explanation:

Given that:

Number of questions answered correctly in the test = 20

Percentage scored in the test = 80%

Let,

x be the total number of questions on test.

We know that 80% of the test is 20 questions, therefore,

80% of x = 20

[tex]\frac{80}{100}x=20\\0.8x=20[/tex]

Dividing both sides by 0.8

[tex]\frac{0.8x}{0.8}=\frac{20}{0.8}\\x=25[/tex]

Hence,

The student had a total of 25 questions on his test.

Answer:

Subtract 3.6 from both sides.

Step-by-step explanation:

Given

[tex]x + 3.6 = -1.7[/tex]

Required

Solve in one step

There are two ways to go about it.

1. Collect Like Terms

[tex]x + 3.6 = -1.7[/tex]

3.6 and -1.7 are like terms, so the equation becomes

[tex]x = -1.7 - 3.6[/tex]

[tex]x = -5.3[/tex]

2. Subtract 3.6 from both sides

[tex]x + 3.6 = -1.7[/tex]

This becomes

[tex]x + 3.6 - 3.6 = -1.7 - 3.6[/tex]

[tex]x = -5.3[/tex]

Hence, the last option answers the question.

Answer:

Option 2and 5 are correct.

Step-by-step explanation:

-Add -3.6 to both sides

-Subtract 3.6 from both sides
