3 · 20 = 5 · x

60 = 5x

Divide by 5:

12 = x.

Answer:

so x=12

Step-by-step explanation:

[tex]\frac{3}{5}=\frac{x}{20}\\ by cross multiplication[/tex]

3×20=5×x

60=5x

dividing 5 on both sides

60/5=5x/5

x=12

Step-by-step explanation:

√(-100)

Use the imaginary number rule  [tex]i=\sqrt{-1}[/tex]

√(-1) × √(100)

i × √(10²)

i × 10

= 10i

Answer:

It does not have a square root because it is a minus digit.

Step-by-step explanation:

The square root of one number is the number which is multiplied by itself to form the square number.

But, no negative number has a square root, because

- x - = +

+ x + = +

As you can see, no two same signs multiply together to form a negative.

Hope this helps.

Good Luck

Answer:

1 hour 26 Minutes

Step-by-step explanation:

Tanya needs 2 hours to do the job.

Pat needs 5 hours to do this same job.

Tanya's rate  [tex]=\frac{1}{2}[/tex]

Pat's rate[tex]=\frac{1}{5}[/tex]

Let the number of hours it will take both of them =x

Rate when two of them work together  [tex]=\frac{1}{x}[/tex]

Therefore:

[tex]\frac{1}{2}+\frac{1}{5}=\frac{1}{x}\\$Taking lowest common multiple$\\\frac{5+2}{10}=\frac{1}{x}\\\\\frac{7}{10}=\frac{1}{x}\\\\$Cross multiply$\\7x=10\\x=1.43$ hours[/tex]

[tex]0.43 X 60 =25.8 \approx 26$ minutes[/tex]

Therefore: 1.43 hour = 1 hour 26 Minutes

It will take both of them approximately 1 hour 26 minutes to  the job.

Answer:

y = 22x - 83

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given m = 22, then

y = 22x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = 88 + c ⇒ c = 5 - 88 = - 83

y = 22x - 83 ← equation of line

Answer:

y=22x-83

Step-by-step explanation:

To find equation plug the numbers in y=mx+b form

5=22(4)+b

5=88+b

Minus 88 on both sides

-53=b

So equation is:-

Y=22x-83

Step 1) Solve for the amount of money Kevin and Emily used to spend in a year for rent

1375 x 12 = 16500

Step 2) Solve for the amount of money Kevin and Emily spend in a year now for rent

(950 x 12) + 275 = 11675

Step 3) Subtract the new amount of money per year from the old amount of money per year to find the savings in the first year

16500 - 11675 = 4825

Kevin and Emily will save $4,825 the first year if they move to a new apartment.

Answer:

d.tigers have a great IQR because they were some very heavy tigers.(high outliers)

Answer:

The correct option is;

There are no solutions

Step-by-step explanation:

From the graph of the inequality, with the y-intercept = 1 and slope = 3 for the blue shaded inequality

The equation is y > 3x + 1

While that of the other red shaded inequality, the slope is 3 and the y-intercept = -3

The equation is y < 3x - 3

Given that the two inequalities are parallel line that their domains do not overlap, we have that there are no solutions as the y-coordinate values of  y > 3x + 1 are always larger for a given x-coordinate value than the y-coordinate value of y < 3x - 3.

Answer:

No solution is correct.

Step-by-step explanation:

I took the test

Answer:

A. 4 2/3 hours

B. (i) 9 4/5 hours

(ii) 1 19/30

Step-by-step explanation:

Firstly, to find the number of hours he used in visiting old folks, what we have to do is to multiply the fraction of hours he used by the total number of hours.

Mathematically, that would be;

4/7 * 8 1/6

8 1/6 is same as 49/6

So the number of hours he spent visiting old folks would be ;

49/6 * 4/7 = 14/3 = 4 2/3 hours

B. What we do here is simply multiply the fraction now by what he spent last year.

That would be 1 1/5 * 8 1/6 hours

= 6/5 * 49/6 = 49/5 = 9 4/5 hours

ii) Now we want to know how much more time will be spent this year than last year.

What to do here simply is to subtract the time taken last year from what we have this year

That would be;

49/5 - 49/6 = 49/30 = 1 19/30

This is through the alternate interior angles theorem. Angles Q and T pair up as one alternate interior set of angles that are the same measure. The same thing applies to angles X and R.

The identical arrow markers on segments XQ and TR show that those segments are parallel. Segment TQ is one transversal cut (forming alternate interior angles Q and T). Segment XR is the other transversal cut (forming alternate interior angles X and R).

We could say "angle XRT" or "angle TRX" instead of "angle R", though its ideal to use shortcuts whenever possible. The same applies for the other angles as well.

Answer:

C = 22π; A = 121π.

Step-by-step explanation:

To find the circumference of a circle, you do pi times the diameter. That would be 22pi.

To find the area of a circle, you do pi * r^2. The radius is the diameter divided by 2. That is 22 / 2, which is 11. Then, the area would be pi * 11^2 = pi * 121 = 121pi.

So, C = 22pi; A = 121pi.

Hope this helps!

Answer:

C = 22π, A = 121π

Step-by-step explanation:

formula for circumference is C=2πr. C= 2π(11) therefore C=22π

formula for are is A=πr² therefore  A=π(11)²= 121π

3(pr)^2=3p^2r^2

Answer:

p(x) = 8x - 20

Step-by-step explanation:

revenue from selling x shirts is f(x) = 15x

The cost of buying x shirts is c(x) = 7x + 20

p(x) = f(x) - c(x)

To solve this, we need to substitute value of f(x) and c(x) in formula for p(x)

p(x) = f(x) - c(x)

p(x) = 15x -( 7x + 20)

=>  p(x) = 15x - 7x -20

=>  p(x) = 8x -20

Thus, profit is p(x) = 8x - 20.

Can i have brainliest

x-2 is a factor so x = 2 is a root of f(x)

This is because f(x) = (x-2)*g(x) for some polynomial g(x). We don't have to worry about what g(x) is equal to as it doesn't affect the status of the root we're after.

So,

f(x) = 0

(x-2)*g(x) = 0

x-2 = 0 or g(x) = 0

x = 2 or g(x) = 0

This shows how the factor x-2 leads to the root x = 2

Therefore, f(2) = 0

Answer: Choice D

Answer:

Last one is the correct option.

Step-by-step explanation:

A root or zero of a polynomial are the value (s) of X that cause the polynomial equal to zero.

Find attached to this question the diagram of the cube.

Reference for the attached image: This diagram was obtained from Education Quality and Accountability Office (EQAO) PDF

Answer:

128cm³

Step-by-step explanation:

The diagram of the box shows it has a side length of 9.2cm

Volume of a cube =( Length)³

Volume of a cube =( 9.2cm)³

= 778.688cm³

We are told in the question that the decoration packed in the cube has a volume of 651 cm³.

The amount of empty space remaining in the box is calculated as:

778.688cm³ - 651cm³

= 127.688cm³

Approximately to the nearest whole number = 128cm³

Answer:

0.28

Step-by-step explanation:

Given in question that,we have to decrease by 72%.that means from 100% of total, 72% should be decreased. that means an overall of 28% will be left. so if you make a number into 28% of it, it implies that you have decreased that number by 72%.so from this,we can say that we have to make the number 28%.that means we have to multiply the number with 28/100 which is equal to 0.28.

Answer:

No, he is wrong

Step-by-step explanation:

To find that probability, the first thing we need to know is the total number of coins present.

Mathematically, that would be 3 + 2 + 3 = 8

Since there are 8 coins, the probability of selecting a dime is number of dimes/total number of coins = 2/8 = 1/4

The probability we want to work with is that the two selections are dimes, let’s say with replacement.

That means; first selection is a dime and second selection is also a dime

Mathematically in probability, the term and means that we have to multiply our results.

So the probability that both are dimes would be 1/4 * 1/4 = 1/16
