Which equation represents this scenario?


a. 10r + 5 + 64

b. 5(10r) = 64

c. 10r - 64 = 5

d. 5 - 10r = 64

Answer:

AB = 9.85 units

Answer:

4.8

Step-by-step explanation:

Answer:

4.8 miles

Step-by-step explanation:

Let's make a proportion using this setup:

miles/minutes=miles/minutes

We know that Nicole runs 6 miles in 55 minutes. We don't know how many miles she runs in 44 minutes, so we can say she runs x miles in 44 minutes.

6 miles/55 minutes=x miles/44 minutes

6/55=x/44

Now, we have to find x. To do this, we need to get x by itself. x is being divided by 44. To undo this, multiply both sides by 44, since multiplication is the opposite of division.

44*(6/55)=(x/44)*44

The 44s on the right cancel, so we are left with:

44*6/55=x

4.8=x

Nicole can run 4.8 miles in 44 minutes

Answer:

She ordered 85.7 packages as dog food

Step-by-step explanation:

Let b represent bird food, d represent dog food and c represent cat food.

The bird food is 4 times as much dog food. This can be represented as b = 4d

Also, the dog food is half the amount of cat food, it can be represented as d = 1/2c. Therefore, c = 2d

The total feed is 600.

Therefore dog feed + cat feed + bird feed = 600

d + 2d + 4d = 600

7d = 600

d = 600/7 = 85,7

She ordered 85.7 packages as dog food.

Answer:

The correct answer is 6.

Step-by-step explanation:

There are "six" blue marbles in the given bag, which is the correct answer would be an option (D).

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Given that bag contains 15 marbles. The probability of randomly selecting a green marble is One-fifth.

The probability of randomly selecting a green marble and then randomly selecting a blue marble is 1/5 x P(blue), where P(blue) is the probability of selecting a blue marble.

As per the question, the probability of this event is 2/25, so we can set up the equation 1/5 x P(blue) = 2/25.

Solving for P(blue), we find that P(blue) = 2/5.

Since the probability of selecting a blue marble is 2/5, and there are 15 marbles in the bag, the number of blue marbles in the bag must be 15 x (2/5) = 6.

Therefore, the number of blue marbles in the bag must be 6.

Answer: 24%

Step-by-step explanation:

A company is expanding its building area from 16,500 square feet to 20,460 square feet. To calculate the percentage increase in the area of the building space, we first find the difference. This will be:

20,460 - 16,500 = 3960

We then divide the difference by the former building area and then multiply by 100. This will be:

3960/16500 × 100

= 0.24 × 100

= 24%

The percentage increase of the area of the building space is 24%.

Given Information:

Principle amount = P = $6,000

Interest rate = r = 4% = 0.04

Period in years = t = 5

Required Information:

How much interest will he earn in 5 years = ?

Answer:

Amount of interest = $1,299.92

Step-by-step explanation:

Using the formula given in the question,

[tex]B = P(1 + r )^{t}[/tex]

Where B is the final amount, P is the initial amount, r is the interest rate and t is the number of years

[tex]B = P(1 + r )^{t}\\\\B = 6,000(1 + 0.04)^{5}\\\\B = 7,299.92[/tex]

The amount of interest earned is

[tex]Amount \:of\: interest = B - P \\\\Amount \:of \:interest = 7,299.92 - 6,000\\\\Amount \:of \:interest = 1,299.92[/tex]

Therefore, Quincy has earned $1,299.92 in terms of interest by investing  $6,000 in a savings account at the rate of 4% annual interest for a period of 5 years.

It was colder on Wednesday morning than Monday morning.

Step-by-step explanation:

(How I know)

-Friday did not have the coldest temperature because Wednesday did.

-it became warmer after Wednesday

-It was colder on Wednesday morning than on Tuesday morning

--8 degrees is colder than -2 degrees.

It was colder on Wednesday morning than Monday morning. Then the correct option is D.

The degree of warmness and coldness is determined by the temperature.

Anna sees a thermometer each morning when she walks out of her house to get on the school bus.

In the following table, she recorded the outdoor temperature each morning for five days.

      Days                         Temperature

   Monday                               -2 °C

  Tuesday                               -3 °C

Wednesday                            -8 °C

  Thursday                             -5 °C

    Friday                                 0 °C

If temperature is negative, then it means more coldness.

It was colder on Wednesday morning than Monday morning.

Then the correct option is D.

Step-by-step explanation:

Answer:

Magda is incorrect

Step-by-step explanation:

Given

Formula:

[tex]K = \frac{P}{2.59M}[/tex]

Population Density of Canada = 3.57 people per km²

Population of Russia = 143.96 million

Land Mass of Russia = 6.593 million square miles

Required

Which country has a greater population density.

First, the population density of Russia needs to be calculated using the given formula;

[tex]K = \frac{P}{2.59M}[/tex]

Here, P = 143.96 million

M = 6.593 million square miles

Substitute these values in the above formula;

[tex]K = \frac{143.96}{2.59 * 6.593}[/tex]

[tex]K = \frac{143.96}{17.07587}[/tex]

[tex]K = 8.43[/tex] people per square miles

Before we can make any comparison, we have to convert the unit of K to people per square kilometre.

From unit of standard conversion;

1 square miles = 2.58999 square kilometre

Hence;

[tex]K = \frac{8.43}{2.58999}[/tex]

[tex]K = 3.25483882177[/tex]

[tex]K = 3.25[/tex] people per km²

Given that the Population Density of Canada = 3.57 people per km²

And We solved for the Population Density of Russia = 3.25 people per km²

By Comparison, the Population Density of Canada is greater than the Population Density of Russia;

Hence, Magda is incorrect

The percentage change in temperature is 19.0%.

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, the temperature rises from 21c to 29c.

The change in temperature is:

29c - 21c

= 4c

The percentage change in temperature from 21c is:

percentage change = (4c/21c)×100

                                 =4/21×100

                                 = 19.0%

(would really, reallly appreciate the brainliest)

Step-by-step explanation:

2x+9 < 9

can be rewritten as

2x < 0

and therefore

x < 0

the other inequality states that x hat to be bigger then -12

so all integers that satisfy -12 < x < 0 are in the set we search, but be aware that -12 and 0 don't fall into this set, bc -12 for example isn't bigger than -12

Answer:

The integers that satisfy both inequalities are -5, -6, -7, -8, -9, -10 and -11.

Step-by-step explanation:

Firstly, you have to solve the inequality :

[tex]2x + 9 < 0 [/tex]

[tex]2x < - 9[/tex]

[tex]x < - \frac{9}{2} [/tex]

[tex]x < - 4.5[/tex]

Next, given that x is greater than -12 but smaller than -4.5 so the inequality for x is :

[tex] - 12 < x < - 4.5[/tex]

Integer is a positive or a negative number but 'cannot be written in the form of decimal'. So the integers that satisfy both inequalities are :

[tex] - 12 < x < - 4.5[/tex]

[tex]x = - 11, - 10, - 9, - 8, - 7, - 6, - 5[/tex]

Answer: P = 96 - 30 + 9.48

Step-by-step explanation:

The price of the jacket is $96.

The discount is 31.25% and

The sales tax is 9.875%

To find the price paid, we subtract the discount from the original price and add the sales tax. This will be:

P=96 - (31.25% × 96)+(9.875% × 96)

P = 96 - 0.3125(96) + 0.09875(96)

P = 96 - 30 + 9.48

P = 75.48

Where,

P stands for the final price.

The first term (96) shows the initial price.

The second term (-30) is about the discount which has to be negative.

The final term (+9.48) is about the sales tax which must be added to have the total price.

2nd sphere has r1 = 15

=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 15^2 = 900pi

=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 15^3 =4500pi
