Answer:

1 pizza

Step-by-step explanation:

Of the pizzas recently sold at Pizza Pies, 10 had pepperoni and 2 did not.

This means, the total number of pizzas sold is

10 pepperoni + 2 pizzas without pepperoni = 12 pizzas

Hence, the number of 6 pizzas that would be sold without pepperoni is calculated as:

From the above question,

12 pizzas = 2 pizza without pepperoni

6 pizzas = x

Cross Multiply

12 pizzas × x = 6 Pizzas × 2 pizza without pepperoni

x = 6 Pizzas × 2 pizza without pepperoni/12 pizzas

x = 1 pizza without pepperoni

Therefore, 1 pizza would not have pepperoni out of 6 pizzas sold

Answer:

12/25=48%

Step-by-step explanation:

total=denominator=12+13=25

numerator=no of cherries=12

12/25=x/100

1200=25x

x=48%

A percentage is a number or ratio that represents a fraction of 100. 

Percentage formula = (Required number / Total number) x 100

The percentage of cherries is 48%.

A percentage is a number or ratio that represents a fraction of 100. 

Example:

50% = 50 /100 = 1/2

25% = 25/100 = 1/4

We have,

Number of cherries = 12

Number of strawberries = 13

The total number of fruits:

= 12 + 13

= 25

Percentage formula = (Required number / Total number) x 100

The percentage of cherries:

= (Number of Cherries / Total number of fruits) x 100

= (12 / 25) x 100

[ 25 x 4 = 100 ]

= 12 x 4

= 48%

Thus,

The percentage of cherries is 48%.

Equation D, y = 1.75x + 6.25

Step-by-step explanation:

We know that the common ratio is 1.75 which means that the data would go up by $1.75 each time and then an additional of 6.25 is also there. Hence, 1.75 would be the slope and 6.25 would be the intercept of the equation.

Answer:yˆ=−0.175x2−3.786x+121.119

look at picture

Step-by-step explanation:

The quadratic regression equation for the data set is:

y^ = -0.175x²-3.786x+121.119

Quadratic regression is the process of determining the equation of a parabola that best fits a set of data. This set of data is a given set of graph points that make up the shape of a parabola. The equation of the parabola is y = ax² + bx + c, where a can never equal zero.

According to the given problem,

Let us choose any value of x,

x = 10

For this value of x we can see that the respective value of y= 50

Substituting the value of x in the equations to see which equation satisfies the value of y as 50.

Substituting the value of x in the equation:

y^ = -0.175x²-3.786x+121.119

y^ = 50

Hence, we can conclude that y^ = 0.175x² - 3.786 + 121.119 is the quadratic regression equation for the given data set.

Answer:

640

Step-by-step explanation:

5% of 400 is 20

20 x 12 is 240

400 + 240 = 640

Forgive me if I'm wrong. I suck at math XD

The amount for the month of December is $640.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Gabriel deposits $400 into a savings account in January If he deposits 5% more each month.

The December month deposit is calculated as,

5% of 400 is 20

20 x 12 is 240

400 + 240 = $640

Therefore, the amount for the month of December is $640.

find the volume

find 80% of whats left

divide by 1.75 (gas price)

sorry if its wrong but im human

will give you the steps but try to do the problem by yourself.  

Start by finding the volume of the tank

Multiply 1.75 ft and 1.25 ft then covert the sum to inches by multiplying it by 12.

Then multiply that amount by the ll inches and you have the volume.

Since the tank is 20% full divide the volume by five, take the number you get from that and subtract it from the origanl volume.

Now you have the amount you need to fill.

Since it is 3.

Divide the amount you need to fill by 77 and you get the cost to fill the tank.

Answer:

Wanda's recipe needs 0.09 more cups of flour per bagel.

Step-by-step explanation:

First, you have to find the amount flour that each of them need for one bagel by dividing the cups of flour they use by the number of bagels:

Wanda: 3.54/6= 0.59 cups of flour

Eli: 2.5/5=0.5 cups of flour

Now, you have to subtract the amount of flour Eli needs from the amount that Wanda needs:

0.59-0.5=0.09

According to thiss, the answer is that Wanda's recipe needs 0.09 more cups of flour per bagel.

Prob = 13/1024 = 0.0127

Step-by-step explanation:

Prob {A correct answer} = Correct option / Total options = 1/4

Prob {A wrong answer} = Wrong options / Total options = 3/4

Prob [3 answers correct] = P (3 correct ,& 2 wrong) or P (4 correct ,& 1 wrong) or P (5 correct, & no wrong)

= [ (1/4) x (1/4) x (1/4) x (3/4) x (3/4) ]  +  [ (1/4) x (1/4) x (1/4) x (1/4) x (3/4) ] + [ (1/4) x (1/4) x (1/4) x (1/4) x (1/4) ]

( 9/1024 ) + ( 3/1024 ) + ( 1/1024 )

13/1024 = 0.0127

Step-by-step explanation:

sin x = 12/16 = 0.75

x = arc sin 0.75 = 48.6°

cos x = 36/40 = 0.90

x= arc cos 0.90 = 25.8°

cos x = 10/15 = 0.6667

x= arc cos 0.6667 = 48.2°

tan x = 30/18 = 1.6667

x = arc tan 1.6667 = 59.0°

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

Explanation:

The diagram shows that PT = 4 and QR = 5. Since QR is a radius of the circle, this means that the other radii segments TR and RS are also 5 units long.

Note how PR = PT+TR = 4+5 = 9, and how this segment is the hypotenuse for the right triangles PQR and PRS.

Picking either triangle, we have one known leg of 5 units (the radius mentioned earlier) and the other is unknown. The unknown leg is tangent to the circle, and recall that a tangent segment is always perpendicular to the radius at the point of tangency. So that's why we have right triangles.

Apply the pythagorean theorem to find the length of PQ and PS (both are the same length)

a^2 + b^2 = c^2

a^2 + 5^2 = 9^2

a^2 + 25 = 81

a^2 = 81 - 25

a^2 = 56

a = sqrt(56)

a = sqrt(4*14)

a = sqrt(4)*sqrt(14)

a = 2*sqrt(14)

The exact length of PQ and PS is 2*sqrt(14) units.

---------

We have enough to find the perimeter of quadrilateral PQRS. We add up the exterior sides. That means we ignore the interior segment PR.

perimeter = PQ+QR+RS+SP

perimeter = 2*sqrt(14)+5+5+2*sqrt(14)

perimeter = 10+4*sqrt(14)

Answer:

A

Step-by-step explanation:

Here the base (3.2) is greater than 1 and the exponent (t) is positive.  Thus the graph will have shape A.

The correct graph for the given function h(t)=0.6×[tex]3.2^{t}[/tex] will be upward increasing so option (A) will be correct.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given function is  h(t)=0.6×[tex]3.2^{t}[/tex]

As t is increasing then the term [tex]3.2^{t}[/tex]  will also go to increase since 3.2 is greater than 1.

Hence the value of the graph will go to increase as x increases so it is clear that option (A) will be correct.
