There are 7 trucks for every 5 cars . If there are 21 trucks, how many cars are there?

Answers

Answer 1

Answer:

15 cars

Step-by-step explanation:

If there are 7 trucks for every 5 cars, the ratio is 7:5. So if there are 21 trucks, that's 7 x 3, which means we also multiply 5 by 3 = 15

Answer 2
I think that there would be 15 cars

The linear function is represented by the equation y = -3/5x -2. What can be determined of this equation written in slope-intercept form? Check all that apply

Answers

Answer:

We can determine the slope m and the y-intercept of the linear function when the linear equation y = -3/5x -2 is written in slope-intercept form.

Thus, we concluded that:

The y-intercept b = -2The slope m = -3/5

Step-by-step explanation:

The slope-intercept form of the linear/line function

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Given that the linear function is represented by the equation

[tex]y\:=\:-\frac{3}{5}x\:-2[/tex]

comparing with the slope-intercept form of the linear/line equation

[tex]y = mx + b[/tex]

Therefore,

The slope m = -3/5The y-intercept b = -2

Hence, we can determine the slope m and the y-intercept of the linear function when the linear equation y = -3/5x -2 is written in slope-intercept form.

Thus, we concluded that:

The y-intercept b = -2The slope m = -3/5

What is 38 percent of 10 oranges

Answers

Answer:

The answer is 3.8

Explanation:

Move the decimal over once to the left.

Answer:

3.8 oranges.

Step-by-step explanation:

Step 1: Our output value is 10.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 10=100%.

Step 4: Similarly, x=38%.

Step 5: This results in a pair of simple equations:

10=100%(1).

x=38%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

10/x= 100%/38%

Step 7: Again, the reciprocal of both sides gives

x/10 = 38/100

---> x=3.8$

Therefore, 38% of 10 is 3.8

A statistics student has a mean score of 92 in the first 3 tests. Suppose there are a total of 4 tests and all of them have equal weight. You can also assume that there is no extra credit in the last test. What is the best possible final average this student can get

Answers

Answer:

The best possible final average this student can get is 94.

Step-by-step explanation:

The average score is given by the sum of the scores of all tests divided by the number of tests.

In this question:

First three tests: Mean score of 92, so total score of 92*3 = 276

Best possible score, with 4 tests:

In the first three, the total is 276. The best possible score is with a grade of 100 in the fourth test. The score will be:

[tex]M = \frac{276+100}{4} = \frac{376}{4} = 94[/tex]

The best possible final average this student can get is 94.

Which is the equation of a line parallel to the line with the equation:
y = 1/4x + 2

Answers

answer:

y=1/4x-7

Step-by-step explanation:

equations with the same slope are parallel no matter the y-intercept

Answer:

I don't think it's specified but I can tell you the slop has to stay the same but the y-intercept ha

s to be a different number.

if over a certain point the all you have to do is plug the points into x and y and remove the y intercept. An example is what line is parallel to y=1/4x+2 and crosses point (4,2).

Then you first have to plug in x and y and remove the y intercept to find a new y intercept. 2=1/4(4)+B

Next is to put together common like terms. 2=1+B

Then subtract one because that's it's opposite leaving B=1

then you substitute or replace the old y intercept with the new one making the answer Y=1/4x+1

I hope this will help you.

If you borrow $1,000 at a 5% interest for six months what amount would you need to pay back if you paid back the principal and interest at the end of the loan?

Answers

Answer:

A = $1,025.00

I = A - P = $25.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Putting time into years for simplicity,

6 months / 12 months/year = 0.5 years.

Solving our equation:

A = 1000(1 + (0.05 × 0.5)) = 1025

A = $1,025.00

The total amount accrued, principal plus interest, from simple interest on a principal of $1,000.00 at a rate of 5% per year for 0.5 years (6 months) is $1,025.00.

Step-by-step explanation:

[tex]2\frac{2}{3}[/tex]

To convert a mixed number to an improper fraction all you need to do is......

Multiply the denominator of the fraction (3), by the whole number (the big number in front of the fraction) (2), and then you add the numerator....

Denominator times the whole number ( 3 * 2 = 6)

Now add the numerator with what you got ( 6 + 2 = 8)

Now the "8" will be the new numerator, and the denominator stays the same "3".

Improper fraction: [tex]\frac{8}{3}[/tex]

__________________________________________________________

[tex]1\frac{4}{7}[/tex]

We can do the same steps we did for the one above

Multiply the denominator (7) by the whole number (1), and then add the numerator (4)....

Add the numerator to the answer you got ( 7 + 4 = 11)

Now "11" will be the new numerator, and the denominator stays the same "7".

Improper fraction: [tex]\frac{11}{7}[/tex]
