Shawn said that in standard notation,
7.142 x 107 will have 7 zeros after the
2 because the exponent is a 7. Is he
correct? Why or why not?

Answers

Answer 1

Answer:

Shawn is incorrect.

Step-by-step explanation:

The decimal is moving 7 places to the right.  The 2 is the third digit, so there will be 4 0s after it.

what is the value of x in the equetion 3/4(1/4x+8)-(1/2+2)-3/8(4-x)-1/4x?​

Answers

3/4*1/4= 3/16 or 0.1875 (you times 3 by 1 and 4 by 4)
3/4*8= 6
first bracket = 3/16+ 6
1/2+2= 2 1/2 or 2.5
second bracket = -2.5
-3/8*4= -1.5
-3/8*x= -3/8x or -0.375x
third bracket= -0.375x
so

(0.1875+6) - (2.5) - (0.375x) - (0.25x)
collect like terms
6.2 - 2.5 = 3.7
0.375x - 0.25x = 0.125x
3.7-0.125x is your answer in decimal form

(3/16+6/1) - (2 1/2) - (3/8x-1/4x)

(6 3/16 - 2 1/2 )

(3 11/16)

3/8x-1/4x= 1/8x

final answer = 3 11/16 - 1/8x

PLEASE HELP NOW ASAP Peyton is collecting data on the lunch habits of students at Nicholas Orem Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Nicholas Orem Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *

Answers

Answer:

1000 students buy a lunch

Step-by-step explanation:

14 bring lunch

20 buy lunch

There are 34 kids in the sample class (14 + 20)

14/34 = .412 = 41.2%

There are 1700 students.

14 / 34  = x / 1700 cross multiply

14 (1700) = 34x

23,800 = 34x   Divide each side by 34

23800/34 = 34x/34

23800/34 = x

700 = x

So 700 students bring a lunch.

1700 - 700 = 1000

1000 students buy a lunch.

.A length, originally 9cm, is increased so that the ratio of the new length to the old length is 13:3. What is the new length​

Answers

Answer:

The new length is 39 cm

Step-by-step explanation:

We will use the ratio method to solve the question

∵ A length, originally 9cm, is increased

∴ The original length = 9 cm

∵ The ratio of the new length to the old length is 13 : 3

→ That means the ratio is ⇒ New : Original is 13 : 3

∴ The ratio New : Original = 13 : 3

→ By using the ratio method

→  New  :  Original

→  13      :   3

→  x        :   9

→ By using cross multiplication

x × 3 = 13 × 9

∴ 3x = 117

→ Divide both sides by 3

∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{117}{3}[/tex]

x = 39

∵ x represents the new length

∵ x = 39

The new length is 39 cm

Answers

Answer:

The temperature now is 20°F

Step-by-step explanation:

The given parameters are;

The initial morning temperature in Buffalo New York = 10°F

The rise in temperature in Buffalo New York = 10°F

The current temperature in Buffalo New York = The initial morning temperature in Buffalo New York + The rise in temperature in Buffalo New York

∴ The current temperature in Buffalo New York = 10°F + 10°F = 20°F.

Answer:

The number of candy packages is going to be represented by the variable c.

6.50 – 5.75

18 – 6.5  -  1.15c ≥ 5.75

11.5  -  1.15c ≥ 5.75

Subtract 11.5 from both sides

-1.15c ≥ -5.75

Divide both sides by -1.15 and flip the sign.

You answer be c ≤ 5

Answers

Answer:

The total cost of the taxi service is the flat free and the total amount that is based on the distance. Let x be this distance. The equation that would best represent the situation is,

                                             1.25 + 0.75x = 14

Solving for x gives the answer of 17. Thus, Henri can afford to travel 17 miles.

v =

Answers

Answer:

The solution is: v = [tex]9\frac{1}{2}[/tex]

Step-by-step explanation:

Given equation is:

[tex]\frac{4}{5}(v-7) = 2[/tex]

The given equation is a linear equation in one variable. The solution requires isolating v on one side of the equation. Simple equality properties can be used to solve the equation.

So,

Multiplying both sides of equation with 5

[tex]5*\frac{4}{5}(v-7) =5* 2\\{4}(v-7) = 10[/tex]

dividing both sides by 4

[tex]\frac{4(v-7)}{4} = \frac{10}{4}\\v-7 = \frac{5}{2}\\[/tex]

Adding 7 on both sides

[tex]v-7+7 = \frac{5}{2}+7\\v = \frac{5+14}{2}\\v = \frac{19}{2}\\v = 9\frac{1}{2}[/tex]

Hence,

The solution is: v = [tex]9\frac{1}{2}[/tex]
