Answer:

D. 5.32 cubic units

Step-by-step explanation:

Volume of a cone = ⅓πr²h

Radius (r) = 1.52 units

Height (h) = 2.2 units

π = 3.14

Substitute

Volume = ⅓*3.14*1.52²*2.2

Volume = 5.32 cubic units

Answer:

D. 5.32 cubic units

Step-by-step explanation:

Step-by-step explanation:

(1/4)^3

the cube root goes for the top part of the fraction and the bottom part of the fraction

((1^3)/(4^3))

4x4x4=64

so the answer is 1/64

Answer:

y = 1.5x - 1 or y = 1 1/2x - 1 or y = 3/2x - 1

Step-by-step explanation:

y = mx + b

b is the point on the y

y = -1

so

b = -1

now the slope

m = rise/run

m = 3/2

so

y = 1.5x - 1

Plz mark as brainliest if correct!!!

Answer:

y=3/2x-1

Step-by-step explanation:

slope:3/2

Answer:

is that an exponent?

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's use "completing the square" to solve this quadratic:  x^2 − 18x + 58 = 0

We want to rewrite the terms "x^2 - 18x" in the form '(x - h)^2 - h^2 and leave the terms '58 = 0' as they are:

Taking half of the coefficient of x (which coefficient is -18), we get -9.  We square this -9, obtaining 81, and then rewrite

"x^2 - 18x"   as  "x^2 - 18x" + 81 - 81."  To this we must append '58 = 0":

x^2 - 18x + 81 - 81 + 58, or x^2 - 18x + 81 - 23 = 0

Now the first three terms condense to the expression

(x - 9)^2, which is then followed by "-23":

(x - 9)^2 = 23

Solve this for x.  Taking the square root of both sides, we get

x - 9 = ± √23

so that one root is x = 9 + √23

and the other is x = 9 - √23

Answer:

60

step-by-step explanation:

Answer: 60

Step-by-step explanation: Basically just multiply the whole number by 2 :)

Whenever you see something times 0.5, just know that its going to be that number times 2 (like another half of that number if you understand)

Why? Because 0.5 is basically like a one half (1/2) and you flip the stuff. since 0.5 is a half, here's a tip. Whenever you're dividing with decimals, use the formula KCF (keep, change, flip) (what my teacher taught me before)          

Here's a drawing to better explain:

Answer to the first question: 7/10ths of a mile

Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: [tex]\frac{2*2}{5*2} = \frac{4}{10}[/tex]. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.

Answer to the second question: Daniel read three (3/10) more books

Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: [tex]\frac{4*2}{5*2} = \frac{8}{10}[/tex]. For Edgar, that would mean: [tex]\frac{1*5}{2*5} = \frac{5}{10}[/tex]. So, Daniel read 3 more books than Edgar.

Answer to the third question: 2/4 mile (or 1/2 a mile)

Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.

Answer and Step-by-step explanation:

1. Convert [tex]\frac{2}{5}[/tex] to have a denominator of 10.

[tex]\frac{2}{5}[/tex] × [tex]\frac{2}{2}[/tex] = [tex]\frac{4}{10}[/tex]

[tex]\frac{3}{10} + \frac{4}{10} = \frac{7}{10}[/tex]

Jeremiah ran [tex]\frac{7}{10}[/tex] of a mile in total.

2. Convert the denominators of all the fractions to have a 10.

[tex]\frac{1}{2}[/tex] × [tex]\frac{5}{5} =\frac{5}{10}[/tex]

[tex]\frac{4}{5}[/tex] × [tex]\frac{2}{2} = \frac{8}{10}[/tex]

Daniel read [tex]\frac{3}{10}[/tex] more books than Edgar, since 8 books is more than 5 books by 3 books.

3. Convert [tex]\frac{1}{4}[/tex] to have a denominator of 8.

[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{2} = \frac{2}{8}[/tex]

[tex]\frac{2}{8} +\frac{2}{8}= \frac{4}{8}, or\frac{1}{2}[/tex]

Jared drove [tex]\frac{4}{8}[/tex], or [tex]\frac{1}{2}[/tex] miles in total.

#teamtrees #WAP (Water And Plant)

Answer:

when you ask multiple questions at once, it feels more like i'm doing your HW for you, not that i'm  helping you understand , i'll answer these but you really should have been able to do these if you really did all the others.  Did you just get tired out?  Why can't you do 4, 6, 8?  what is it that you don't understand?

Step-by-step explanation:

4)   old price = 120   to new price = 240

they ask what is the percent change

How much is the change ( in amount )

the "How much is obvious right?  Old price 120 , new price 240.. change is $120

the percent is   change / old price = 120 / 120  = 1  and to put it in percent , multiply by 100 , so 100 % change

6) old price = 250   amount of change -100

so what percent of 250 is 100  

100 / 250 = 0.4   to get it in percent multiply by 100  = 40%

  old price + change = new price

250 +  ( -100)  =  150   new price is $150

8) 5% mark up  , amount of change = $2.50

so 5% of what = 2.50 ?

X* 5% = 2.5

X* 0.05 = 2.5

X=2.5/0.05

X= $50  was the old price

old price + amount change = new price

50 + 2.50 = 52.50

$52.50 is the new price

Answer:

Area = 68.75 ft²

Step-by-step explanation:

Area of the trapezoid = ½(a + b)*h

Where,

a = 13.6 ft + 5.9 ft = 19.5 ft

b = 8 ft

h = 5 ft

Area of trapezoid = ½(19.5 + 8)*5

Area of trapezoid = ½(27.5)*5

Area = 68.75 ft²

Answer:

[tex]45^{o}[/tex]

Answer:

x = 119

z = 28

Step-by-step explanation:

To find x: Because of same-side exterior angles, you can add x and 61 together to find 180 degrees.

x + 61 = 180

Subtraction: x = 119

To find z: Use given quantities, not found variables for most accurate answer. Because of opposite exterior angles, you can equal them to each other.

61 = 5z - 79

Addition: 140 = 5z

Division: 140/5 = 5z/5

Final Answer = 28 = z

Answer:

(a) 3.025

Step-by-step explanation:

The computation is shown below:

In the case when Abishola acheives all As in the senior year, so the final GPA  Is  

The net GPA is 3

So,

(2.7 × 90 + 30 × x) ÷ 120 = 3

30x = (360 - 2.7 × 90)

x = (360  - 2.7 × 90) ÷ (30)

= 3.9

As she can score till 4 so 3.9 could be possible  

In the case when she score 4 on her final year so her GPA is  

= (2.7 × 90 + 30 × 4) ÷ 120

= 3.025

Answer:

x > -10

Step-by-step explanation:

5x + 13 > -37

subtract 13 from each side:

5x > -50

x > -10

Answer:

X >/ -10 (imagine this is more or equal to symbol lol)

Step-by-step explanation:

1. subtract 13 from both sides

5x +13-13 >/ -37 -13

2. Simplify

5x >/ -50

3. solve for x (which means divide by 5)

5x/5 >/ -50/5

x>/ -10

Answer:

B. a = rⁿ

C. a¹/ⁿ = r

Step-by-step explanation:

ⁿ√a = r

The above expression can be simplified as follow:

1. ⁿ√a = r

Recall:

ⁿ√a = a¹/ⁿ

Therefore,

a¹/ⁿ = r

2. ⁿ√a = r

Take the n square of both side

(ⁿ√a)ⁿ = rⁿ

(a¹/ⁿ)ⁿ = rⁿ

a = rⁿ
