Answer 1

constant of proportionality is 4

equation: x/y = 4

explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.

Answer 2

Answer:

Constant: 4 i think because you can divide 20 by 4 to get 5 and 24 by 4 to get 6. So then probably the equation: is y=4x BUT DON'T PAY ATTENTION TO ME I GOT A B+ IN MATH:)

StartFraction part Over whole EndFraction = StartFraction 300 Over 100 EndFraction = StartFraction 12 Over question mark EndFraction. How many granola bars did Talia eat last week? 12 is 300% of what number? The percent in the problem written as a ratio: part = _______ whole = ______ 300 divided by _______ is equal to 12. 100 divided by ______ is equal to _____

Answers

The number of granola bars that were eaten last week is 4.

Since we are given the information that Talia ate 12 granola bars, which was 300% as many as she ate last week. Therefore, the equation that can be used in solving the question will be:

= 300% × x = 12

3x = 12

x = 12/3

x = 4

Therefore, the number of granola bars that were eaten last week is 4.

Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years. Describe how you could estimate the total variation in water level.

NO SAMPLE RESPONSES FROM ED PLEASE

Answers

Answer:

The total variation in water level is -3.3

Step-by-step explanation:

Round 1.05 mm to the nearest whole number the result is -1.1 then round 2.48 which the result will be equal to 3. The total variation in water level is -3.3

The total variation in water level is -2.6.

We have,

Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years.

The decrease of the rate -1.05 mm/year can be rounded to -1.

Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.

Thus, the total variation in water level is -2.6.

Name a combination of coins that is 130% of the value of a dollar.

Answers

Answer:

5 quarters, 1 nickel

Step-by-step explanation:

A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given: A dollar and to find its 130% equivalent in the form of coins.

A nickel is worth 5 cents

A dime is worth 10 cents

A quarter is worth 25 cents

Now a dollar is equivalent to 100 cents

Thus 130% of a dollar is equivalent to

130/100 ×100 +100 =230 cents

Therefore a combination of 8 quarters which is equal to 200 cents and 2 dimes and 2 nickel is equal to 230 cents as

8×25+2×10+2×5=230 cents.

Hence, A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.

What is Triangle Inequality?

According to the Triangle Inequality Theorem, any two triangle sides must add up to more than the third side's length.

Given:

As, the sum of two sides of the Triangle is greater than third side.

1. 25 feet, 30 feet, 60 feet

Then, 25+ 30 <60

2. 40 feet, 60 feet, 70 feet

40+ 60 > 70

60+ 70>40

70+ 40 > 60

3. 40 feet, 175 feet, 220 feet

40+ 175 < 220

4. 80 feet, 150 feet, 230 feet

80+ 150 = 230

Hence, the lengths of the sides of a triangle can be 40 feet, 60 feet, 70 feet.

Evaluate xy for x = –9 and y = 5.
A –4
B 45
C –45
D –14

Answers

Answer:

Step-by-step explanation:

9 times 5 is 45. when ur multiplying and there's only one negative sign, the answer will always be negative.

C. -45

These types of problems can be fairly simply once you understand substitution. Substitution is when we put in values (in this case -9 and 5) in their set variable (x and y in this case.)

The problem states that x=-9 therefore we put in -9 for x in the multiplication of xy so it looks like this: (-9)(y). Next we want to substitute in the y value which is 5 so that we now have (-9)(5).

Because there is no plus or minus sign, along with a division sign, we then MULTIPLY these two numbers because the variables are connected so -9*5 would equal to -45.
