Answer:

X°

Step-by-step explanation:

there’s no other clues to what it could be, and since it’s x it would be X°

Answer:

0.058863

Step-by-step explanation:

Answer: 160 children and 174 adults

Step-by-step explanation:

Let x represent the children and y represent the adults.

Create two equations:

x+y=334

1.50x+2y=588

Subtract 1.50x from the equation, then divide by 2:

y=294 - 0.75x

Plug it into the first equation then solve.

x+294-0.75x=334

x=160

Subtract 160 from 334 to get y:

y=174

===========================================================

Explanation:

We're told that 1 square foot is 144 square inches (this is from 12*12 = 144, since 12 inches = 1 ft).

So because of this, 360 square feet converts to 360*144 = 51,840 square inches.

One gallon of paint can cover 51,840 square inches.

Now let's find the surface area of the sphere, aka ball.

It has a radius of r = 4.75 inches, so,

SA = 4*pi*r^2

SA = 4*pi*(4.75)^2

SA = 90.25pi

SA = 283.528736986479 which is approximate

The surface area of one ball is roughly 283.528736986479 square inches.

Divide the amount of area the paint can cover over the surface area of one basketball:

(51,840)/(283.528736986479) = 182.838609415709

This rounds down to 182. We round down because we won't have enough paint to cover the 183rd basketball.

One gallon of paint can cover 182 basketballs.

Answer: what?

Step-by-step explanation:

I don’t know

Answer:

Just multiple each fraction by 2 on the denominator and numerator.

For the drawing part, all you have to do is draw lines until you get the number of the denominator.

Step-by-step explanation:

For. Example, 2/4 times 2 equals 4/8

So for this u would draw lines till you count that there are 8 lines.

I hope this helped you.

Have a nice day.

Answer:

No, 10/24 is not equal to 8/20

Step-by-step explanation:

10/24=5/12 when simplified

8/20=2/5 when simplified

Therefore, 10/24 is not equal to 8/20. I hope this helps, and mark me brainliest, please!

Thank you have a wonderful Sunday!

Answer:

100 + 50x = 950

100 - 100 + 50x = 950 - 100

50x = 850

50x/50 = 850/50

x = 17

Answer:

7

Step-by-step explanation:

17 times 60 is 1020

1020 plus 30 is 1050

2 times 60 is 120

120 plus 30 is 150

1050 divided by 150 is 7

Answer:

Answer:

H = 42

Step-by-step explanation:

18 ÷ 108 = [tex]\frac{1}{6}[/tex]

7 ÷ [tex]\frac{1}{6}[/tex] = 42

You can check to make sure your answer is right by entering your proportions into a calculator. For example, [tex]\frac{42}{108}=0.38888888888...[/tex] and [tex]\frac{7}{18}[/tex] also equals [tex]0.38888888888...[/tex] so since they match, we know it is correct.

Answer:

Step-by-step explanation:

-2/3(-3b-24) = 2(b+8)

6b/3+48/3 = 2b+16

2b+16 = 2b+16 => equivalent

Is -2/3(-12b-6+9b-18) equivalent to 2(b+8)?

To find out, simplify the left side.

Multiply every term in the parentheses by 2/3.

(8b + 4 - 6b + 12)

Simplify.

(2b + 16)

Factor out 2.

2(b + 8)

We conclude that -2/3(-12b-6+9b-18)

equals 2(b + 8).

Answer:

12   never     mind it is 72

Step-by-step explanation:

6x6=36

36x2=72

Answer:

6 x 6

Step-by-step explanation:

because when You multiply x2 is by the same number

so it's 6 x6 = 36

Equivalent fractions are fractions that represent the same value or amount, despite having different numerators and denominators.

In other words, equivalent fractions have the same ratio or proportion, but may be written in different forms.

For example, the fractions 1/2 and 2/4 are equivalent fractions because they represent the same amount, which is half of a whole.

Also, 3/5 and 6/10 are equivalent fractions because they both represent three-fifths or 60% of a whole.

Answer:

k = -2

Step-by-step explanation:

2 way to solve:

1st: 8x²-13x-4k = 8(x²-(13/8)x-(k/2))

if 2 roots: a and 1/a

8(x-a)(x-1/a) = 8(x²-(13/8)x-(k/2))

x²-(a+1/a)x+1 = x²-(13/8)x-(k/2)

1 = -(k/2)

k = -2

2nd: 2 roots of 8x²-13x-4k      x=(-b±√b²-4ac)/2a

x = (13±√169-4*8*(-4k))/16 = (13±√169+128k)/16

(13+(√169+128k))/16 = 16/ (13-(√169+128k))  ... root1=1/root2

(13+(√169+128k))*(13-(√169+128k)) = 16*16

13² - (√169+128k)² = 256

169-169-128k = 256

-128k = 256

k = -2

Answer:

= -25

Step-by-step explanation:

Answer:

The sum is;

x⁸ + x²

Step-by-step explanation:

Here, we want to add two polynomials

To add, we check the power of both values in the expression

As we can see, the power is not the same

What this mean is that we can not add the two terms beyond this written expression

So we have the value of the polynomial expression as still being the same

The answer is D.

Step-by-step explanation:

28/7 = 4 and 19-4 = 15.

Answer:

a=7 b=24 c=25

Step-by-step explanation:

Leg a=7

Leg b=24

According to Pythagorean theorem: a^2+b^2=c^2

49+576=c^2

C^2=625

c=25

Answer:

Step-by-step explanation:

This is a right triangle, so we may apply the Pythagorean Theorem.  The two leg lengths are 7 and 24 respectively, and so the length of the hypotenuse is

√(7² + 24²) = 25

Answer:

260π or id we take π=3.14 816.4

Step-by-step explanation:

h=13ft

r=10ft

A=2πr(h+r)=2*10*13*π=260π=816.4

Answer:

No

Step-by-step explanation:

As you probably know, triangles have 3 sides. The longest side is called the hypotenuse. In this case, the hypotenuse is 10.3. Now, you might or might not know the pythagorean theorem, which states that the a² + b² =c ².

In this case, we can say that 4.4 is a and 8.3 is b. Now if we square 4.4 and add it to 8.3 squared, we get 88.25. However, if you square 10.3, you get 106.09. Thus, the values cannot be this way. So, your answer is no.

Answer:

Part A: (3, 2)

Part B: 5

Step-by-step explanation:

Point B of the parallelogram is the top right dot on the graph. In order to find its coordinate, we simply trace the dot's trajectory back to the x and y axis accordingly. If we look under the dot we see that its x-axis is 3 and if we look to the left of the dot we see that its y-axis is 2. Therefore, the coordinate of the fourth vertex B is (3, 2)

To calculate the length of side AB we simply count the number of squares between them, which looking at the graph we can see is 5 squares. Therefore the length of AB is 5
