Complete Question

Jada is making lasagna and pizzas for a large party. Her lasagna recipe calls for 1 1/4 cups of tomato paste, and her pizza recipe uses 1/2 cup of tomato paste per pizza. She will double her lasagna recipe and make 5 pizzas. Write and evaluate an expression for how many 3/4- cup cans of tomato paste she will need in all.

Answer:

The evaluate and for how many 3/4-cup cans of tomato she need in all is 20/3

Step-by-step explanation:

Step 1

From the question, we are told that:

1 single lasgna recipe uses: 1 1/4 cups of tomato paste = 5/4 cups

If she doubles her recipe, the number of cups of tomato paste =

2 × 5/4 cups of tomato paste

= 10/ 4 = 5/2 cups of tomato pastes

Step 2

From the question, we are told that:

1 Pizza recipe = 1/2 cup of tomato pastes

5 Pizza =

5 × 1/2 cup of tomato paste

= 5/2 cups of tomato paste

Steps 3

The total number of cups of tomato paste Jada will use in making double lasagna and 5 pizzas is calculated as

= 5/2 + 5/2

= (5 + 5)/ 2

= 10/2

= 5 cups.

Step 4

We are asked to evaluate how many 3/4 -cup cans of tomato she need in all.

This means we should find how many 3/4 - cup cans can be found in the total number of cups of tomato paste that Jada used.

Total number of cups that Jada used = 5 cups of tomato paste

The number of 3/4-cup cans in 5 cups is calculated as:

5 ÷ (3/4)

= 5 × 4/3

= 20/3

Therefore, the evaluate and for how many 3/4-cup cans of tomato she need in all is 20/3

Answer:

P=21

Step-by-step explanation:

The solution to the equation P - 18 = 3 for P is P = 21

From the question, we have the following parameters that can be used in our computation:

P - 18 = 3

Add 18 to both sides of the equation

so, we have the following representation

18 + P - 18 = 3 + 18

Evaluate the like terms on the right hand side

This gives

18 + P - 18 = 21

Evaluate the like terms on the left hand side

This gives

P = 21

Hence. the solution is 21

Step-by-step explanation:

To combine like terms, we need to find similar numbers. 5x and -2x can be simplified because they both end with x. 6x^2 is different because it ends with x^2. So to simplify, we subtract 2x from 5x to get 3x, and we add 6x^2 to get our answer.

Answer: [tex]6x^2+3x[/tex]

Answer:

6x² +3x

Step-by-step explanation:

We are given the expression:

[tex]6x^2 + 5x-2x[/tex]

and asked to combine like terms. Let's analyze the terms.

6x² ⇒ has a variable, x²

5x  ⇒ has a variable, x

2x  ⇒ has a variable, x

Now, let's group the like terms, 5x and -2x.

[tex]6x^2+ (5x-2x)[/tex]

Next, combine the like terms. Subtract 2x from 5x.

[tex]6x^2+(3x)[/tex]

[tex]6x^2+3x[/tex]

The expression 6x² +5x-2x simplified is 6x² +3x

Answer:

P (greater than 3) = 1/2

Step-by-step explanation:

A standard number cube has 6 sides, numbered 1 through 6.

We want to find the probability of rolling a number greater than 3. To find this probability, create a fraction. The numerator is the amount of numbers greater than 3 and the denominator is the total amount of numbers.

P(greater than 3)= numbers greater than 3/ total numbers

There are 3 numbers that are greater than 3 (4, 5 and 6).

There are 6 total numbers (1, 2, 3, 4, 5, and 6)

P (greater than 3) = 3/6

This fraction can be simplified. Both the numerator and denominator can be divided by 3.

P (greater than 3) = (3/3) / (6/3)

P (greater than 3)= 1/ (6/3)

P(greater than 3) = 1/2

The probability of rolling a number greater than 3 is 1/2.

Answer:

its -2

Step-by-step explanation:

The value of k in equation k/4 + 3 = 14 is 44 and in the other equation 4k + 3 = 14 it will be 11/4.

A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.

We have given equation as

k/4 + 3 = 14

subtract by 3 both sides

k/4 + 3 -3 = 14 -3

k/4 = 11

On cross-multiplication, the equation becomes

k = 11(4)

k = 44

similarly,

4k + 3 = 14

subtract by 3 both sides

4k +3 - 3 = 14 - 3

4k = 11

On cross-multiplication, the equation becomes

k = 11/4

Thus, the value of k in both the equation is 44 and 11/4.

Answer:

C=6π=18.84 ( if π=3.14)

Step-by-step explanation:

distance around the edge of the pond means the circumference of the circle=

C=2πr

C=2π(3)

C=6π=18.84 ( if π=3.14)

The approximate distance around the edge of the pond is 18.84 feet.

Given that, a circular pond has a radius of 3 feet.

The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.

We know that, the circumference of a circle is 2πr.

Now, 2×3.14×3

= 18.84 feet

Hence, the approximate distance around the edge of the pond is 18.84 feet.

Answer:

The answer is 231 cm^3

Step-by-step explanation:

This is a volume question so we will bring out the question comment first:

Diameter= 7 cm

Height =6 cm

We have to change the diameter to radius so we will do: the diameter which is 7 divided by two which will be 3.5.

We can now start proper.

Formula of volume=pile r square h

22/7 or 3.14 times the radius raised to power 2 times the height=

Answer:

Speed of plane in still air = 780 km/h

Speed of air = 52 km/hr

Step-by-step explanation:

Let the speed of plane in still air = u km/h

Let the speed of air = v km/h

Against the air, the resultant speed = (u-v) km/hr

With the air, the resultant speed = (u+v) km/hr

Formula for speed is given as:

[tex]Speed = \dfrac{Distance}{Time }[/tex]

Given that:

Distance = 5824 km

Time taken against the wind = 8 hours

Speed against the wind:

[tex]u-v = \dfrac{5824}{8} \\\Rightarrow u-v = 728 ...... (1)[/tex]

Time taken with the wind = 7 hours

Speed with the wind:

[tex]u+v = \dfrac{5824}{7} \\\Rightarrow u+v = 832 ...... (2)[/tex]

Adding (1) and (2):

[tex]2u=1560\\\Rightarrow u = 780\ km/hr[/tex]

By equation (1):

[tex]780-v=728\\\Rightarrow v = 52\ km/hr[/tex]

Speed of plane in still air = 780 km/h

Speed of air = 52 km/hr

Answer:

a = 5.5, d = 11/3

Step-by-step explanation:

An arithmetic progression is a sequence of number such that the difference between consecutive numbers is a constant. It is given by:

[tex]a_n=a+(n-1)d\\a_n \ is\ the \ nth\ term, d\ is\ the\ common\ difference\ and\ n \ is\ the \ number\ of\ terms[/tex]

The sum of fifth and sixth terms is 44

Therefore:

a + 4d + a + 5d = 44

2a + 9d = 44                       (1)

The sum of the first n terms is:

[tex]S=\frac{n}{2} (2a+(n-1)d)\\Therefore\ the\ sum\ of\ the\ first\ 18\ term\ is:\\\\S=\frac{18}{2} (2a+(18-1)d) = 9(2a+17d)=18a+153d\\\\The\ sum\ of\ the\ first\ 10\ term\ is:\\\\S=\frac{10}{2} (2a+(10-1)d) = 5(2a+9d)=10a+45d[/tex]

Since the sum of the first eighteen terms is thrice the sum of the first ten terms:

18a + 153d = 3(10a + 45d)

18 a + 153d = 30a + 135d

18a  - 30a + 153d - 135d = 0

-12a + 18d = 0                    (2)

Multiply equation 1 by 6 and add to equation 2:

72d = 264

d = 11/3

Putting d = 11/3 in eqn 2

-12a + 18(11/3) = 0

-12a + 66 = 0

12a = 66

a = 5.5

Then the value of angle LPN is 45° because figure LKNP is a rectangle so the sum of the angles should be 360°so 120°+120°+75°+angle LPN is 360°so the value of angle LPN is 45°

The value of x is also 45° because of vertically oposite angles theorem
