The Smith’s drove 3,000 miles in 75 hours. At this rate, how long will it take them to drive 4,000 miles?

Answer:

2x=34+56

x=90÷2

therefore x=45

Answer:

Step-by-step explanation:

2x - 56 = 34

2x = 34 + 56

2x = 90

x = 90/2

x = 45

Answer:

49

Answer: 4p(-3q+2)

Step-by-step explanation:

The hcf (highest common factor) of 8 and 12 is 4 so you would put a 4 in front of the bracket.

Then because it has p in both of the numbers you can put p at the front with the 4.

This looks like 4p so far.

After that, you would have to do -12/4=-3

So then because you don’t have a q at the front you would put it with the -3.

This looks like 4p(-3q) so far.

Then, you would have to do 8/4=2.

And as you have a p at the front, you don’t need one with the 2.

This would look like together as 4p(-3q+2)

I hope this helps it’s quite difficult to explain :)

Answer:

Twenty six, 26.

Step-by-step explanation:

12 divided by 6= 2- that's the unit rate.

52 divided by 2=26

Answer:

Step-by-step explanation:

y=mx+b where m=slope and b=y intercept, we are given m=2 so

y=2x+b, using point (3,-3) we can solve for b

-3=2(3)+b

-3=6+b

b=-9

y=2x-9

Answer:

For every 1 Tablespoon, there are 3 Teaspoons

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but I'm assuming that you want to calculate the radius.

Circumference of a circle = 2πr

where Circumference = 18.9 meters

Radius = Unknown

π = 3.14

We then put the values into the formula which will be:

C = 2πr

18.9 = 2 × 3.14 × r

18.9 = 6.28r

r = 18.9 / 6.28

r = 3

The radius = 3 meters

Assuming you probably want to get the diameter, we multiply the radius by 2. This will be:

= 2 × 3

= 6 meters

Answer:

2. The answer should be the last one.

3. The answer should be the first three.

Step-by-step explanation:

Question 2

KE = (1/2)mv²

2KE = mv²

v² = 2KE/m

v = ±√(2KE/m)

Therefore the answer should be the last one.

Question 3

b^(1/2) * b^(5/2)

Remember that the product rule states that b^x * b^y = b^(x+y)

So this means b^(1/2) * b^(5/2) = b^(1/2+5/2) = b^(6/2) = b^3

Also remember that the power rule states that √b = b^(1/2)

so this means b^(6/2) can also be written as (√b)^6

Therefore the answer should be the first three.

If you want to double check all of your answers, just replace b with a number (for example, 2), and plug all of the choices into the calculator. Just make sure you are very careful when typing into the calculator.

Answer:

The answer is C. There are four monkeys at the zoo for every one tiger.

Answer:

a) much smaller

b) little larger

c) little smaller

d) much larger

Step-by-step explanation:

Anything multiplied by a value less that 1 will reduce the size

Anything multiplied by a value larger than 1 will increase the size

(Basically, the larger the value, the less it is shrunk/the more it is expanded)

Answer:

B yuri spend $42

Step-by-step explanation:

8×4=32

32+10=42

3^2 + 10^2 = 109

square root of 109 = 10.4403065089

Answer:

x=10.44

Step-by-step explanation:

10^2+3^2=x^2

100+9=x^2

109=x^2

10.44030651=x

Given:

The ratio of present ages of Sonu and Monu = 7:5

The ratio of their ages after 10 years = 9:7.

To find:

The present ages of Sonu and Monu.

Solution:

Let the present ages of Sonu and Monu are 7x and 5x respectively.

Their ages after 10 years are (7x+10) and (5x+10) respectively.

The ratio of their ages after 10 years = 9:7.

[tex]\dfrac{7x+10}{5x+10}=\dfrac{9}{7}[/tex]

[tex]7(7x+10)=9(5x+10)[/tex]

[tex]49x+70=45x+90[/tex]

[tex]49x-45x=90-70[/tex]

On further simplification, we get

[tex]4x=20[/tex]

[tex]x=\dfrac{20}{4}[/tex]

[tex]x=5[/tex]

Now,

Sonu's present age = [tex]7x[/tex]

                                 = [tex]7(5)[/tex]

                                 = [tex]35[/tex]

Monu's present age = [tex]5x[/tex]

                                 = [tex]5(5)[/tex]

                                 = [tex]25[/tex]

Therefore, the present ages of Sonu and Monu are 35 and 25 respectively.

Answer:

Fraction: x = 2197/204

Decimal: 10.76960

Step-by-step explanation:

Switch Sides: 2.03 +2.04x + 1=25

Group Like Terms: 2.04x + 2.03 + 1 =25

Add The Numbers 2.03 + 1 = 3.03: 2.04x + 3.03 = 25

Multiply Both Sides By 100: 2.04 * 100 + 3.03 * 100 = 25 * 100

Clarify: 204x+303=2500

Subtract 303 From Both Sides: 204x + 303 - 303=  2500 - 303

Divide Both Sides By 204: 204x/ 204, 2197/204

Simplify: x = 2197/204

Hope This Helped, Have A Great Day!

First, order the number set from least to greatest:

3 , 4 , 4 , 7 , 8 , 9 , 12 , 14 , 16 , 20

Mean: You find the mean by combining all the terms, and dividing by the amount of the terms there are in the number set:

(3 + 4 + 4 + 7 + 8 + 9 + 12 + 14 + 16 + 20)/10

(97)/10 = 9.7

Mean: 9.7

Median: You find the median by first ordering the number set from least to greatest, and finding the middle number. Note that if there is a even number of numbers in the set, you find the mean with the two given median digits:

8 & 9 are the median numbers:

(8 + 9)/2 = (17)/2 = 8.5

Median: 8.5

Mode: The mode is the number(s) in the set that shows up the most:

Mode: 4 (shows up one more time than all other numbers)

Range:  The range can be found by subtracting the least number from the greatest number in the number set:

Range: 20 - 3 = 17

Range: 17
