A)1/4


B)2/3


C)4/15


D)16/15

Answers

Answer 1

Answer:

C

Step-by-step explanation:

Answer 2

The difference in her usage rates in quarts per hour is 4/15, the correct option is C

What is the average rate of change?

The average Rate of Change of the function f(x) can be calculated as;

[tex]f(x) = \dfrac{f(b) - f(a)}{b-a}[/tex]

Given;

Jill used 12 quart of paint in 34 hour

Jill was distracted by texting and used 12 quart of paint in 54 hour

Now,

1/2 per 3/4 hour = (4/3)(1/2) = 2/3 per hour

1/2 per 5/4 hour = (4/5)(1/2) = 2/5 per hour

2/3 - 2/5 = 10/15 - 6/15 = 4/15

Therefore, the rate difference will be 4/15

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

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.

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.

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

Answers

Answer:

C

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.

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.
