To find how many 2/5 cups are needed for 3 cups of sugar, divide 3 by 2/5, resulting in 7.5. Therefore, 7.5 of the 2/5 cups are required.

To calculate how many 2/5 cups are needed for a recipe that requires 3 cups of sugar, you can follow these steps:

Determine the total amount required: The recipe requires 3 cups of sugar.

Determine the measurement of the cup you have: You can measure using only 2/5 cups.

Calculate the number of 2/5 cups needed: Divide the total amount needed by the measurement of the cup you have.

This gives you the equation: 3 cups \/ (2/5 cups) = 15/2 = 7.5. Therefore, you will need 7.5 of the 2/5 cups to measure out 3 cups of sugar.

5.5 divided by 3.5 is 1.57142857 when solved, but when rounded, you will get 1.6, or 1.57.

The expression 'four to the power of -3' equals 0.015625. Since this value is less than 1, Julia will play tennis.

To evaluate the expression four to the power of -3, we have to understand how negative exponents work. A negative exponent means to divide 1 by the base raised to the power of the absolute value of the exponent. So 4^-3 is equivalent to 1/(4^3).

Let's do the maths:
4^3 = 4 * 4 * 4 = 64.
Then, 1/64 = 0.015625.

Therefore, four to the power of negative three is 0.015625.

Julia will choose activities based on the value of the expression - since the value is less than 1, in this case, she would play tennis.

The measure of angle JAM is 55°

Step-by-step explanation:

The correct question is

Find the measure of angle JAM

See the attached figure to better understand the problem

step 1

Find the measure of angle JAK

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

so

m∠JAK=(1/2)[arc KJ+arc LM]

substitute the given values

m∠JAK=(1/2)[170°+80°]=125°

step 2

Find the measure of angle JAM

we know that

m∠JAK+m∠JAM=180° ------> by supplementary angles

we have

m∠JAK=125°

substitute

125°+m∠JAM=180°

m∠JAM=180°-125°=55°

All real numbers greater than or equal to -3.

Step-by-step explanation:

The domain of a function is defined as the x values that are a part of the function. Therefore, looking at the graph, we see that the domain is all real numbers greater than or equal to -3, because the function doesn't contain x values less than -3.

one hour has 60 minutes, each minute has 60 seconds, so then an hour has 60*60 seconds, namely 3600 seconds.  How many miles does Seth travel in 3600 seconds?

[tex]\bf \begin{array}{ccll} miles&seconds\\ \cline{1-2} 1&57.1\\ x&3600 \end{array}\implies \cfrac{1}{x}=\cfrac{57.1}{3600}\implies 3600=57.1x \\\\\\ \cfrac{3600}{57.1}=x\implies 63.05 \approx x[/tex]

Answer:

In order to find miles per hour we must first change the time given to us (57.1 seconds) into hours. We will do this by first changing the seconds to minutes:

57.1 seconds / 60 = .952 minutes

Now we can change our minutes to hours:

.952 minutes / 60= .016 hours

Now to find miles per hour we divide the miles by our time:

1 mile / .016 hours = 63.04 mph

This statement is not true.

If a number is whole number, it will not always be a natural number. An example of a whole number that is not a natural number is 0. Think of natural numbers as counting number so 1, 2, 3, 4, ... and so on. Whole numbers are natural numbers but they also include 0. When we count up, we usually don’t starts with 0 so it’s not a natural number but it is a whole number.

Therefore, if a number is a whole number, it does not necessarily have to be a natural number.

Answer:

The value of x is 7

Step-by-step explanation:

we know that

If two figures are congruent, then the corresponding angles and the corresponding sides are equal

In this problem

Triangles ABC and DEF are congruent

ABC≅DEF

therefore

AB=DE ----> equation A

AC=DF ----> equation B

BC=EF ----> equation C

Substitute the given values in the equation B

[tex]8=2x-6[/tex]

Solve for x

[tex]2x=8+6[/tex]

[tex]2x=14[/tex]

[tex]x=7[/tex]

therefore

The value of x is 7

The draw in the attached figure

In congruent triangles ABC and DEF, given side lengths in ABC and the length of side DF as 2x-6, we set this equal to the corresponding length in triangle ABC. Solving for x gives the result x=7.

The subject of this question is Mathematics, specifically, the principle of congruent triangles in geometry. If two triangles are congruent, then their corresponding sides are equal. In the given congruent triangles, ΔABC and ΔDEF, AB corresponds to DE, BC to EF, and AC to DF. The length of DF is given as 2x-6, and its corresponding side AC in ΔABC is given as 8 units. Thus, we set 2x-6 equal to 8. Solving for x, we add 6 to both sides of the equation, resulting in 2x = 8 + 6. This simplifies to 2x = 14. Finally, dividing both sides by 2 results in x = 7.

Answer:

$5.31

Step-by-step explanation:

If you times $.59 seven times you will get $4.13.  

Then, you will have to add $.59 two times.

Finally, you will get $5.31 .

The cost will be $1.60 in the 19 ounces if the 7 ounces of cola costs $.59.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b, will be the denominator.

The proportion is a nature of a variable to another for example if we say x ∝ y then it will be a direct relation instant if we say x ∝ 1/y then it will be inverse relation.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given,

7 ounces ⇒ cost $0.59

Divide by 7 into both sides

7/7 ounces ⇒ cost $0.59/7

1 ounce ⇒ cost $0.084

Multiply both sides 19

19×1 ounce ⇒ cost $0.084 × 19

19 ounce ⇒ cost $1.60

Hence in 19 ounces of cola, it will cost $1.60.

Answer:

total cost of putting carpet in both rooms is $3692.42

Step-by-step explanation:

given data

living room length = 24 feet

living room width = 15 feet

dining room is square so length and width will be same

dining room length = 13 feet

dining room width = 13 feet

carpet costs =  $6.98 per square foot

to find out

what is the total cost of putting carpet in both rooms

solution

first we find the total area of both room that is

area of living room = length × width      .................1

area of living room = 24 × 15

area of living room = 360 feet²      ...........................2

and

areas of dining room = length × width

area of dining room = 13 × 13

area of dining room = 169 feet²    ...............................3

so total area = add equation 1 and 2

total area = 360 feet² + 169 feet²  

total area = 529 feet²  

and

total cost of putting carpet in both rooms are = total area × carpet costs    .................4

put here value

total cost of putting carpet in both rooms  = 529  ×  $6.98

total cost of putting carpet in both rooms  =$3692.42

The calculated total square footage that needs carpeting is 529 square feet. At $6.98 per square foot, the total cost of carpeting both rooms would be $3,690.42.

The subject of this problem is mathematics, specifically the topic of area calculations and cost analysis. First, calculate the area for both rooms. The area of a rectangle is given by the formula length x width, so the area of the living room is 24 feet x 15 feet which equals 360 square feet. As the dining room is a square, its area is side x side, thus 13 feet x 13 feet equals 169 square feet.

Then, add these to get the total square footage that will need carpeting, which is 360 + 169 = 529 square feet.

Lastly, multiply this total area by the cost per square foot for carpeting. This gives $6.98 x 529 square feet = $3,690.42. So, the total cost of carpeting both rooms would be $3,690.42.
