James and Lucas are eating a pizza. James ate 2/3 of the pizza and Lucas ate 1⁄4 of pizza. Who ate more pizza and by how much?

Answers

Answer: James ate more pizza by 5/12 parts.

Step-by-step explanation:

To solve let us takes the lcm of the denominators 3 and 4

which is 12.

James ate 2/3 * 4/4 = 8/12 parts

Lucas ate 1/4*3/3= 3/12 parts

now, we can see 8/12>3/12

Therefore, James ate more pizza by 8/12-3/12= 5/12 parts.

Answers

The converse of the statement on shoes being clean and new is If the shoes are new, then the shoes are clean.

How to write a converse statement?

When converting a statement that involves two clauses to a converse statement, you should exchange the position of the two clauses to make a converse statement.

This means that if you had a statement as (if a then b) the converse statement is (if b than a). The statement, "If the shoes are clean, then the shoes are new" would then be "If the shoes are new, then the shoes are clean."

Quinn knit a total of 4 centimeters of scarf over 2 nights. how many nights will quinn have to spend knitting in order to knit a total of 70 centimeters of scarf?

Answers

The nights required by Quinn in order to knit a total of 70 centimeters of the scarf is equal to 35.

The number of nights required by Quinn in order to knit a total of 70cm of the scarf can be calculated using multiplication. Multiplication can be described as one of the four basic arithmetic operations in which we perform the repeated addition of the same number or value. This problem can be solved using cross-multiplication as follows;

2 nights = 4 cm of scarf

x nights = 70 cm of scarf

70 × 2 = 4(x)

140 = 4(x)

x = 140 / 4

x = 35

Therefore, Quinn will have to spend 35 nights knitting in order to knit a total of 70 centimeters of the scarf.

can has 338 nuts. Below is Mary's work
to find the total number of nuts.

Answers

The total number of nuts is 15210 and the missing number is 5

Number of cans of mixed nuts = 45 cans

Number of nuts in each can = 338 nuts

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors.

Finding the total number of nuts we get:

Total number of nuts = Number of cans*Number of nuts in each can

In 1992, a postage stamp cost $0.25. In 2004, a postage stamp cost $0.37. What is the average rate of change in postage cents per year?

Answers

Answer: 0.01 (One cent per year)

Step-by-step explanation:

We need to find the price the stamp increased per year.

The difference in years is 12.

2004 - 1992 = 12

The difference in price is 0.12.

0.37 - 0.25 = 0.12

So to find price increase per year we do the following:

$0.12/12 = 0.01

$0.01 is one cent per year.

second subtract 49 from both sides

-40 = 10y

flip it

10y = -40

now divide both sides by 10

y = -4

that is your answer

Answer: 7y+9=3y+49

We move all terms to the left:

-7y+9-(3y+49)=0

We get rid of parentheses

-7y-3y-49+9=0

We add all the numbers together, and all the variables

-10y-40=0

We move all terms containing y to the left, all other terms to the right

-10y=40

y=40/-10

The ground temperature at an airport is 11 °C. The temperature decreases by 7 °C for every increase of 1 kilometer above the ground. What is the temperature outside a plane flying at an altitude of 5 kilometers?


The temperature outside a plane flying at an altitude of 5 kilometers is
°C.

Answers

Under the linear assumption of temperature and altitude, the temperature outside the plane is - 24 °C.

What is the temperature outside a plane flying at a given altitude?

In this problem we must determine the temperature outside the plane on the assumption that the temperature decreases linearly with the altitude:

T(z) = T' + (ΔT / Δz) · z

Where:

T' - Temperate at ground level, in degrees Celsius.Δz - Level change, in kilometers.ΔT - Temperature change, in degrees Celsius.

If we know that T' = 11, Δz = 1 and ΔT = - 7, then the temperature at an altitude of 5 kilometers is:

T(5) = 11 + (- 7 / 1) · 5

T(5) = 11 - 35

T(5) = - 24

Answers

For any given Triangle ABC, its medial triangle is constructed by finding the midpoints of its three sides (Segments AB, BC, and AC) and constructing segments to join these midpoints.

An important property of the medial triangle is that it divides the original triangle into four smaller, congruent triangles that are each similar to the original triangle.

With this in mind we now that the four triangles are congruent. Then:

Answers

The amount of money that Kyle will have after 5 years is $690.

How to calculate the interest?

From the information, Kyle invests $600 which earns 3% annual simple interest for 5 years.

The formula for the amount is given as:

A(t)=P (1+rt)

where P = principal = $600

R = rate = 3%

T = time = 5 years

This will be:

A(t)=P (1+rt)

A = 600 [ 1 + (3% × 5)]

A = 600 (1 + 0.15)

A = 600(1.15)

A = 690
