The percentage of questions did Tomi know the answer for is,

⇒ 90%

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

We have to given that;

Out of 30 questions on the math's test Tomi knew the answer to 27 of them.

Hence, The percentage of questions did Tomi know the answer for is,

⇒ 27/30 × 100

⇒ 90%

Thus, The percentage of questions did Tomi know the answer for is,

⇒ 90%

Step-by-step explanation:

When you see this notation, it means plug in -1 for x in the function.

f(-1) = 3^((-1)-4)

f(-1) = 3^-5

f(-1) = 1/3^5

f(-1) = 1/243

Step-by-step explanation:

Answer:

The baby weighed 14.5 pounds at the end of 8 months

Step-by-step explanation:

Proportions

We know a baby weighed 7.25 pounds at birth.

It's given at the end of 8 months, the baby weighed twice its birth weight.

This means the baby weighed 2*7.25 = 14.5 pounds at the end of 8 months.

The baby weighed 14.5 pounds at the end of 8 months

Answer

Here the area and the width of the rectangular fence are given. We have to find length of the fence.

( diagram )

The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.

Given that area is 500 square feet and width is 20 feet.

Substituting values in formula,

⇒500=l×20

⇒20/500

​

= 20/1×20

​

    [ Dividing both sides by 20 ]

⇒l=25  feet

∴ length of rectangular fence is 25 feet.

Hence, the answer is 25.

Answer:

the answer would be A.

Answer:

Joseph used [tex]5\frac{2}{3}\ yards\ of\ cape[/tex]

Step-by-step explanation:

Total fabric available = 17 yards

fraction used = one-third = 1/3

Let us convert this fraction to actual number

He used one-third of total

= [tex]\frac{1}{3}\ of\ 17\\=\frac{1}{3} \times \frac{17}{1} = \frac{17}{3}[/tex]

To convert to mixed number, look for the closest number to the numerator that the denominator in the fraction can divide, and write it as the whole number in the mixed fraction, the remainder becomes the numerator of the new fraction:

The closest number to 17 that 3 can divide without a remainder is 15 and 3 can divide 15, 5 times, while the remainder becomes 2

[tex]\therefore \frac{17}{3} = 5\frac{2}{3}\ yards\ of\ cape[/tex]

Answer:

Miguel has $63

Lisbeth has $11

David has $21

Step-by-step explanation:

let Miguel share be M

let Lisbeth share be L

let David share be D

from the question, we know that

M=3D

L=D-10.

M+L+D=95

thus,

3D+(D-10)+D= 95

3D+D-10+D= 95

5D-10 = 95

5D= 95+10

5D= 105

D= 105/5

D= 21.

thus,

M = 3D = 3×21

= $63

L = D-10 = 21-10

= $11

(63+21+11)$ = $95

Answer:

Step-by-step explanation:

The best way to find out the answer to your question is to graph the cubic. As you can see, the y intercept is (0,16).

How was this obtained. notice that if x = 0 then

f(0) = 2(3*0+4)(0^2 + 2)

f(0) = 2(4)(2)

f(0) = 16 just as the graph tells us.

The length of a rectangular birthday party invitation is 9 inch.

The length of a rectangular birthday party invitation is 1 inch less than twice its width.

Area of the invitation 15 square inches.

what is the area of the rectangle?

A=length× width

That is,the area of a rectangle is length times width.

let x be the width rectangle

width = x

length = 2x - 1

[tex]Area= 15 square inches[/tex]

Using these variables, set up the equation for area.

x(2x - 1) = 15

Solve the equation for x.

[tex]2x^{2} - x = 15[/tex]

Subtract 21 on both sides of the equation.

[tex]2x^{2} - x - 15=0[/tex]

Which method we use to factor the polynomial?

FOIL method

Factor using FOIL, if possible.

(2x +5)(x - 5) = 0

Set the factors equal to zero and solve for x.

2x  = -5 and x - 5 = 0

x =- 5/2 or x = 5

x =- 2.5 or x=5

Since we cannot accept a negative value for dimensions, we accept the positive value of x:

x = 5

Therefore,

Length = 2(5) - 1

Length = 10-1

Length = 9

Therefore we get the length is 9 inch
