21/24=0.875

therefore 21/24 is a greater fraction

Answer: D

Step-by-step explanation:

Find the scale by dividing the lengths of figure 1 and figure 2. Such as 4/2.4 is 1.66666 etc. Same with 2/1.2 and 5/3. Meaning, if you divide x and y, they should also equal what 4/2.4, 2/1.2, and 5/3 are. Which is D, 5/3.

Explanation:

The angles marked are corresponding angles, since they correspond in the same direction. Both are pointing to the southwest direction.

Since line DE is parallel to line FG, this means the corresponding angles mentioned are congruent.

Set them equal to each other and solve for x.

7x+18 = 81

7x = 81-18

7x = 63

x = 63/7

x = 9

Rewrite as

[tex]\frac{4}{7} *\frac{3}{10} /\frac{1}{6}[/tex]

PEMDAS says do multiplication first

When multiplying fractions, just multiply across.

12/70   / 1/6

When dividing fractions, KEEP CHANGE FLIP.

Keep one of the fractions, change the sign to multiplication, flip one of the fractions.

12/70  * 6/1

72/70

1 2/70

Option D

1  1/35

Answer: 12.7

Step-by-step explanation:

r=d/2

3.5/2=r

r=1.75

v=pir²h

122.5 =piR²h

122.5=pie1.75²h

The frist thing to solve for r sense exponents come before multiplication in bedmask

122.5 =pi3 .06g

so then it's pie times r

122.5=9.61 *h

122.5/9.61=h

12.7=h

Answer: h≈12.73in

Answer:

15 people suggested, 25 did not

Step-by-step explanation:

3 of every 8 so 3:8

There is 40 students in total, so 40/8=5. 5*3=15

15 people suggested, 25 did not

Answer:

15 students suggested a rainbow-themed party.

25 students did not suggest a rainbow-themed party.

Step-by-step explanation:

40 students

3 out of every 8 students suggested rainbow them

40/8 = 5

5 groups = 40 students

1 group = 8 students

3 × 5 (amount of groups) = 15

15 students suggested a rainbow-themed party.

40 - 15 = 25

25 students did not suggest a rainbow-themed party.

Answer:

t= 2

Step-by-step explanation:

Input the given number in the formula given.

110= 55t

divide 55 from both sides

110/55 =55/55t

which then gives you

2 = t

Answer:90

Step-by-step explanation: If you do 275 divided by 3 it equals 90

Answer: 8,700

Step-by-step explanation:

lets say you have 500 animals, and you decide to get another 500, but you decide that you want an extra 500, and then your kid says that they want another 500 animals. You now have 2000 animals, but you also need 4000 chickens so you now have 6000 animals. Then you need 900 pounds of animal food, but 900 pounds is weird so you get an extra 100 to make your total 1000. But now you need 800 dogs so you now have 2800 animals.

4000 + (500 x 4) + 900 + 100 + 800 = 8,700

Answer:

The answer would be 8700

Answer:

The price is $249

Step-by-step explanation:

In order to find the price from taxes, you have to multiply the % so that it equals 100%, then you multiply the tax you paid by that number. For example, since 20 x 5% is 100%, you multiply $12.45 x 20, which equals $249.

Answer:

Step-by-step explanation:

You want the digits assigned to A, D, G, I, N to satisfy the multiplication problem DID·I = NAG.

Neither D nor I can be 1, because their product is G (not D or I). There can be no carry from that product. (If there were, the result would have 4 digits, not 3.) This means the least significant digit of I·I must be A, and that product must be more than 10.

  I² > 10   ⇒   I ≥ 4

  I ≥ 4   ⇒   D = 2, G = 8 and I = 4

Then we have ...

  DID × I = NAG   ⇒   242 × 4 = 968

The value of NAG is 968.

Answer:

NAG = 968

242 * 4 = 968

2 = D

4 = I

Answer:

Answer:

-4

Step-by-step explanation:

if you multiply 38 x 640 it will be 24320, and if you multiply 18 x 38 it will be 684. add 24320 and 684 it will be 25004 which means she has -4 dollars i believe

Answer:$14

Step-by-step explanation:

640x38 = 24,320

25,000-24,320 = 680

680/18 = 37.7777 and on

so you would make that 37 chargers she can buy with the remaining money.

37x18 = 666 and 680-666=14

Answer:

36 square miles and 23040

Step-by-step explanation:

36 is given and 640x36

Answer:

C. $1,350

Step-by-step explanation:

To find Maren's initial investment, look for the y-axis value when time = 0, because this is when the account was presumably opened.

The graph shows a reading between 1,200 and 1,500, so it can be presumed that the initial investment was aroundabout $1,350.

Let's express these all in decimal form.

-π = -3.14
-3.2 = -3.2
-3 1/4 = -3.25
-√9 (not to be confused with √-9) = -3

So, rank these.

-3 > -3.14 > -3.2 > -3.25
If we revert these to their unsimplified forms:
-√9 > -π > -3.2 > -3 1/4
