Nia is three years older than half Jordans age , if Jordan is eight years old , how old is Nia?

Answers

Hello!

If Nia is three years older than half of Jordan's age, we must divide Jordan's age by 2 (to find half of his age).

Jordan is eight years old:
8 divided by 2 equals 4

4 years old is half of Jordan's age. Now, to find Nia's age, we must add 3 to half of Jordan's age (4).

4+3= 7
Nia is 7 years old.

At Avery Middle School, 273 students responded to a survey asking whether a Bulldog, a Lion, or a Tiger should be a new school mascot. Four times as many students chose Tiger. Twice as many students chose Lion as chose Tiger. How many students chose Lion?
A) 39 students
B) 78 students
C) 156 students
D) 273 students

Answers

the answer is c 156 students

Answer with Step-by-step explanation:

273 students responded to a survey asking whether a Bulldog, a Lion, or a Tiger should be a new school mascot.

Let t students chose tiger

b students chose bulldog

and l students chose lion

then, t+b+l=273

Four times as many students chose Bulldog as chose Tiger.

i.e. b=4t

Twice as many students chose Lion as chose Tiger.

i.e. l=2t

So, t+4t+2t=273

i.e. 7t=273

Dividing both sides by 7, we get

t=39

Number of students who chose lion=2t

= 2×39

= 78

Hence, Correct option is:

The sum of three numbers is 99. The first number is 9 more than the third. The second number is 4 times the third. What are the numbers?

Answers

first number=x+9
second number=4x
third number=x
4x+x+x+9=99
6x=90
x=15
first number=24
second number=60
third number=15

Final answer:

The first number is 24, the second number is 60, and the third number is 15.

Explanation:

Let's assign variables to represent the three numbers. Let x represent the third number. Since the first number is 9 more than the third, we can write the equation:

First number = x + 9

Since the second number is 4 times the third, we can write the equation:

Second number = 4x

Now, we can add the three numbers together, according to the given information:

(x + 9) + 4x + x = 99

Simplifying this equation, we get:

6x + 9 = 99

Subtracting 9 from both sides, we have:

6x = 90

Dividing both sides by 6, we find:

x = 15

So the third number is 15. Plugging this value back into the two other equations, we find that the first number is 24 and the second number is 60. Therefore, the three numbers are 24, 60, and 15.

A) (2, 6) B) (-1, 9) C) (-1, 1) D) (-6, 4)

Answers

D) -6,4. because if it has a slope of 4 which is positive it has to have an uphill slope which passes through -2,5, in order for that to happen you plot it and make the line and count the rise over run till you have the slope of 4.

[tex]\bf slope = {{ m}}= \cfrac{rise}{run}\implies 4\implies \cfrac{4}{1}[/tex]

so the rise is 4 units and the run is 1 unit, ok.

Answers

What we already know is that we have a 40. Eight tenths would look like the following: .8
This is because it says 8 tenths, meaning the 8 is in the tenths place, right after the decimal. So, the answer would be 40.8

The correct representation of forty and eight tenths as a decimal is 40.8.

Here's an explanation for each option:

48.1: This representation is incorrect because it implies forty-eight and one tenth, not forty and eight tenths.

40.8: This is the correct representation. It means forty whole units (40) and eight tenths (0.8).

40.08: This representation is incorrect because it implies forty whole units (40), eight hundredths (0.08), and no tenths.

40.008: This representation is incorrect because it implies forty whole units (40), eight thousandths (0.008), and no tenths.

Therefore, the correct representation of "forty and eight tenths" as a decimal is 40.8.

Jess observed that 60% of the people at the mall on a particular day shopped for clothes 2500 people at the mall did not shop for clothes that day was ? (Only put numeric values, no symbols

Answers

60% of the total people at the mall shopped for clothes....that means 40% of the people didn't shop for clothes. And there were 2500 people who didn't shop for clothes.
so 40% of the total amount of people is 2500
0.40x = 2500
x = 2500/0.40
x = 6250 total people

check...
shop for clothes...60% of 6250 = 0.6(6250) = 3750
did not shop for clothes....40% of 6250 = 0.4(6250) = 2500
total people = 3750 + 2500 = 6250 (correct)

in summary : there were 6250 people at the mall....3750 of them shopped for clothes and 2500 of them didn't shop for clothes <==

Final answer:

To find the total number of people at the mall, we calculate that 2500 represents 40% of the total. Dividing 2500 by 0.40 gives us the total number of people, which is 6250.

Explanation:

Jess observed that 60% of the people at the mall on a particular day shopped for clothes. If 2500 people at the mall did not shop for clothes that day, we can calculate the total number of people who were at the mall. Since 60% is the percentage that shopped for clothes, then 40% represents the percentage that did not shop for clothes. This means that the 2500 people constitute 40% of the total number of people at the mall.

To find the total number of people, we can set up the equation: 40% of total people = 2500. Translating percentages into decimals (40% = 0.40), the equation becomes 0.40 × total people = 2500. To solve for the total number of people, we divide 2500 by 0.40:

Total people = 2500 ÷ 0.40

Total people = 6250

Therefore, the total number of people at the mall that day was 6250.

Ritz can eat 8 apples in 15 minutes. How long does it take to eat 16 apples at same rate?

Answers

Final answer:

To determine how long it takes to eat 16 apples at the same rate as 8 apples in 15 minutes, set up a proportion and solve for the time.

Explanation:

This question demands basic understanding of ratio and proportion in general.

To find out how long it takes to eat 16 apples at the same rate Ritz eats 8 apples in 15 minutes, you can set up a proportion:

8 apples / 15 minutes = 16 apples / x minutes

8/15 × 1/16 = 1/x

1/15 × 1/2 = 1/x

1/x = 1/30

X = 30

A 30-gallon tank initially contains 15 gallons of salt water containing 6 pounds of salt. suppose salt water containing 1 pound of salt per gallon is pumped into the top of the tank at the rate of 2 gallons per minute, while a well-mixed solution leaves the bottom of the tank at a rate of 1 gallon per minute. how much salt is in the tank when the tank is full

Answers

suppose you wanted the tank to hold 100 gallons of water and it was 50 gallons per cubic feet. How many cubic feet would you need? Obviously, 2 cubic feet. How did you get that?? Well, you divided 100 by 50 to get 2.

O.K., now, let's try YOUR problem. 225000 gallons and 7.5 gallons per cubic feet. How many cubic feet do you need? Must be 225,000/7.5 = 30,000 cubic feet

O.K., now we're half way there. we (should) know that the volume of a prism is

l x w x h. We now know the volume must also be 30,000

so l x w x h = 30000
100 x 20 x h = 30000

you should be able to take it from there.

Problem #2

We approach it the exact same way.

It's too hard as stated. Let's make up an easier problem.

suppose 1 gallon took up 5 cubic feet. If you had 10 cubic feet, how many gallons would you have?
well, clearly, you would have 2 gallons. How did you get it?

Now, how many cubic feet in the cylinder? Well you (should) know that the volume of a cylinder is:

Pi r^2h = 3.14 x 25^2 h = 1962.5 h

Now we have a bit of a problem. You didn't tell me how high the tank is. Let us say it is 10 feet.

So, the tank had 19,625 cubic feet.

Go back to the start of this problem and you will know what to do next.

Final answer:

Calculate the amount of salt in a tank given rates of inflow and outflow, and determine the final salt quantity when the tank is full.

Explanation:

A 30-gallon tank initially contains 15 gallons of salt water containing 6 pounds of salt.

Find the initial amount of salt per gallon in the tank: 6 pounds / 15 gallons = 0.4 pounds per gallon.

Calculate the rate of salt being added and leaving the tank: In: 1 pound per gallon × 2 gallons per minute = 2 pounds per minute; Out: 0.4 pounds per gallon × 1 gallon per minute = 0.4 pounds per minute.

Subtract the rate of salt leaving from the rate of salt coming in to find the net rate of salt accumulation: 2 pounds per minute - 0.4 pounds per minute = 1.6 pounds per minute.

How much salt is in the tank when it is full?

Using the net rate of salt accumulation, calculate the time needed to fill the tank: 30 gallons / 2 gallons per minute = 15 minutes.

Finally, calculate the total amount of salt in the tank when full: 15 minutes × 1.6 pounds per minute = 24 pounds of salt.
