Answer: 4 pizzas

Step-by-step explanation:

There are to be 12 people at the party.

Each person is expected to take 1/3 of a pizza.

The total number of pizza needed is therefore:

= No. of people * quantity of pizza

= 12 * 1/3

= 4 pizzas

Note: Answer would be 6 if each guest wanted 1/2 of a pizza.

Answer:

26/20

Step-by-step explanation:

y2-y1 divided by x2-x1

4-24= -20

3-29= -26

-20/-26= m

perpendicular means to switch the numbers and change the sign

a perpendicular slope to -20/-26 is 26/20.

Answer:

Number of apples = 6

Number of oranges = 5

Step-by-step explanation:

At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.

Let

Number of apples = x

Number of oranges = y

x + y = 11 (1)

0.80x + 0.95y = 9.55 (2)

From (1)

x = 11 - y

Substitute into (2)

0.80x + 0.95y = 9.55 (2)

0.80(11 - y) + 0.95y = 9.55

8.8 - 0.80y + 0.95y = 9.55

- 0.80y + 0.95y = 9.55 - 8.8

0.15y = 0.75

y = 0.75/0.15

y = 5

Substitute y = 5 into (1)

x + y = 11 (1)

x + 5 = 11

x = 11 - 5

x = 6

Number of apples = 6

Number of oranges = 5

Answer:y=7(2)^x

Step-by-step explanation:

The exponential function in the form y=ab^x that goes through the given points is f(x) = 7(2)ˣ.

Exponential functions are functions where the independent variable, x is in the exponent.

The general form of exponential function is,

f(x) = abˣ

The function passes through (0,7) and (9, 3584).

Substituting (0, 7),

7 = a b⁰

7 = a  (since b⁰ = 1)

So, a = 7

Function is f(x) = 7bˣ

Now Substituting (9, 3584),

3584 = 7 b⁹

b⁹ = 3584 / 7

b⁹ = 512

b⁹ = 2⁹

b = 2

So the function is f(x) = 7(2)ˣ

Hence the function is f(x) = 7(2)ˣ.

Answer:

y=3.5x

Step-by-step explanation:

Since when x is 0 when y is 0, there is no y-intercept. The ratio with the other values gives the equation y=3.5x, because y is 3.5 times larger than x.

Answer:

147 cubic meters

Step-by-step explanation:

Volume = length x width x height

V = 3 x 7 x 7

V = 21 x 7

V = 147 cubic meters

It's C.

Basically, when youre dividing something, the bases would stay the same but the exponents would change. For division, you'd have to substract the exponent of the denominator from the denominator (of like bases, of course)

In this case, it's 10^8-(-3).

The only reason it's not 10⁵ is because of the negative 3. If it were a positive 3, it would become 10⁵.

The solution for the given equation is 15.

The given equation is 2 = -7/4 + 1/4 x.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, 2 = (-7+x)/4

2×4 = -7+x

8 = -7+x

x = 8+7

x = 15

Therefore, the solution for the given equation is 15.

Answer:

D

Step-by-step explanation:

A.

y= 6x³

to find the inverse substitute x for y and y for x and solve for y

x= 6y³ ; divide both sides by 6

x/6 =y³ ; cube root both sides

(∛x)/ ∛6 = y

so  (∛x)/6  and 6x³ are NOT inverse of each other

B

y= (x+2)/5

x= (y+2)/5; multiply by 5

5x = y+2; subtract 2

y= 5x-2 NOT corect

C

y = 5x-6

x= 5y-6; add 6 to both sides

x+6 = 5y ; divided by 5 both sides

y = (x+6)/5 is NOT correct

D

y=7x -2

x= 7y-2

x+2 = 7y , (x+2) /7 = y so  IS correct

The for second triangle :

Length of Hypotenuse [tex] = \sqrt {(\sqrt 2) ^2 +1^2} =\sqrt {2+1}=\sqrt 3[/tex]

The for third triangle :

Length of Hypotenuse [tex] = \sqrt {(\sqrt 3) ^2 +1^2} =\sqrt {3+1}=\sqrt 4 = 2[/tex]

The for fourth triangle :

The x value for the given partial spiral is √5 units.

We need to solve for x in the partial spiral given.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

From the right triangle 1:

Let the hypotenuse be a.

So, a²=1²+1²

⇒a=√2

From the right triangle 2:

Let the hypotenuse be b.

So, b²=(√2)²+1²

⇒b=√3

From the right triangle 3:

Let the hypotenuse be c.

So, c²=(√3)²+1²

⇒b=√4=2

From the right triangle 2:

The hypotenuse=x

So, x²=2²+1²

⇒x=√5

Therefore, the x value for the given partial spiral is √5 units.

Answer:

7/35 or 20% of the jars are not creamy

Answer:

20%

Step-by-step explanation:

To find the percent of NOT creamy:

35(total peanut butter) - 28(creamy) = 7

Question now is: 7 is what % of 35?

Formula = a(part) = p(percent)*w(whole)

p = a/w

7/35 = 0.2

0.2 is a decimal so multiply by 100 to get 20%
