Answer:

49

Step-by-step explanation:

2+1.5=3.5

49/3.5=14

Answer:

a = 44.1

Step-by-step explanation:

Do the addition in the parentheses first.

a / (3.15) = 14

Multiply both sides by (3.15) to isolate a.

3.15(a/3.15)=14(3.15)

a = 44.1

Answer:

The answer is : 4a + 2b + 8

Step-by-step explanation:

2x2a = 4a

2xb = 2b

+8

Answer:

a. Meg needs to find the part

b. Steve needs to find the percent.

Step-by-step explanation:

A. Does Meg need to find the part, the whole, or the percent.

Meg already knows the whole and the percent.

The whole is the entire number of dogs seen: 16 dogs.

The percent is 50%.

Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.

And she can do with a simple operation:

Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.

B. Does Steve need to find the part, the whole, or the percent.

He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).

Then he needs to find the percent, which he can do using the next operation:

Percent = (part / whole) × 100 = (7/35)×100 = 20%

Step-by-step explanation:

Part 1:

Meg needs to find the whole as 50% of the dogs = 5 therefore 100% equals 10 dogs.

Part 2:

Steve saw 50% out of two dogs meaning that he only saw 1 dog that is a boxer.

B

Answer:

Step-by-step explanation:

6% of 56 is 10.71

6% of 60 is 10

6% of 15

hopefully this answers your question

6% of 56 is 10.71

6% of 60 is 10

6% of 15

After this, I think you may want to multiply 10.71, 10, and 15. Unless you were trying to separate all the numbers. If you weren't, its 1606.5!

Answer:

8.93

Step-by-step explanation:

Answer:

the answer is 8 and 13/14, or 8.93

Step-by-step explanation:

because of PEMDAS, we solve the numbers in the parenthesis first.

2 x 7 = 14.

next, we divide 125 by 14.     125 / 14 =     8 and 13/14

in decimal form, that is 8.93 (rounded up)

hope this helps :D

Answer:

Step-by-step explanation:

Answer:

a) x^2 - x -12

b) 2s^2 - 16s + 24

c) 8s^2 - 8s -48

d) 4x^2 - 16x + 16

Answer:

a. x^2 - x - 12

b. 2s^2 - 16s + 24

c. 8s^2 - 8 - 48

d. 4x^2 - 16 + 16

Step-by-step explanation:

You need to use distributive property find the answer.

(x + 3)(x - 4)

>> (x)(x) = x^2

>>(x)(-4) = -4x

(3)(x) = 3x

(3)(-4) = -12

The result will be x^2 -4x + 3x -12

You can simplify this by adding the like terms:

x^2 -4x + 3x -12

>> x^2 - x - 12

Just do the same for the rest of them by using distributive property.

Hope this helps! Have a great day! Also, let me know if you need an explanation for the rest of them too!

Answer:  95 in is shorter

Step-by-step explanation:

there are 12 in in a foot, so in that case you have to divide 95 in by 12. The answer is 7.91666667 but if you round it up you would get 8, which that is = 8ft but without rounding it up you would get 7.9ft which is less than 8ft. so the answer is 95 in is shorter than 8ft

Answer:

40 nickels

Step-by-step explanation:

1 2/5 to 2 1/3 = 7/5 : 7/3

                      = 21/15 : 35/15

21/15 = 24

35/15 = x

(35/15 * 24) / 21/15

∴ 56 ÷ 21/15

= 40 nickels

Answer:

-42.95ft

Step-by-step explanation:

First, find the change in elevation between where Max starts and where his friends are:

-21.4ft-(-64.5ft)=43.1ft

Since we're told that he makes two equidistant ascents, we know that each ascent would be equal to:

43.1ft/2=21.55ft

Now we take the height that he started at and add the height that he would gain in his first ascent

-64.5ft+21.55ft=42.95ft

Answer:

54

Step-by-step explanation:

Let,

No. of boys = 2x

No. of girls = 3x

2x + 3x = 135

5x = 135

x = 135/5

x = 27

No. of boys = 2x = 2(27) = 54

Answer:

x = 10

Step-by-step explanation:

if there 2 same triangle then they are right triangle

By using Pythagorean theorem for 1 of right triangle, we have

[tex]\sqrt{74} ^{2}[/tex] = [tex]7^{2}[/tex] + [tex](\frac{x}{2}) ^{2}[/tex]

74 = 49 + [tex]\frac{x^{2}}{4}[/tex]

74 - 49 = [tex]\frac{x^{2}}{4}[/tex]

25 = [tex]\frac{x^{2}}{4}[/tex]

therefore, x = [tex]\sqrt{25*4}[/tex] = [tex]\sqrt{100}[/tex] = 10

The previous water level of a lake will be negative 1.1 feet. Then the correct option is A.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

A water level is a number that demonstrates whether the level is above or below typical utilizing positive or negative qualities. After a weighty tempest, the water level of a lake is −5.6 feet. This level is 1/2 times 1.7 feet more than the past water level.

Then the expression is given as,

⇒ −5.6 / 2 + 1.7

Simplify the equation, then we have

⇒ −5.6 / 2 + 1.7

⇒ −2.8 + 1.7

⇒ −1.1

The past water level of a lake will be negative 1.1 feet. Then the right choice is A.
