8993.2x 10³ use the powers of ten rules please help iv been stuck on this​

Answer:

Option (C)

Option (C)

Option (A)

Step-by-step explanation:

Part A.

Frank's walking speed can be represented by the equation.

Equation representing the speed is,

y = 85x

[tex]\frac{y}{x}=85[/tex]

Therefore, walking speed of Frank = 85 meters per minute.

Option (C) will be the answer.

Part B.

Distance walked over the time by Jeffrey is given by the graph attached.

Equation for the speed will be,

y = [tex](\frac{400}{5})x[/tex]

y = 80x

Therefore, walking speed of Jeffrey = 80 meters per minute

Difference in the speed of Frank and Jeffrey = 85 - 80 = 5 meters per minute.

Jeffery walks 5 meters per minute slower than Frank.

Option (C) will be the answer.

Part (C)

Distance traveled by Frank in 16 minutes,

y = 85(16) = 1360 meters

Time taken to travel the same distance by Jeffrey will be,

1360 = 80x

x = [tex]\frac{1360}{80}=17[/tex] meters per minute

Option (A) will be the answer.

Answer:Do you what it in vertex because if you do the answer is (-8,3)

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = - 7(x + 8)² + 3 ← is in vertex form

with (h, k) = (- 8, 3 )

• If a > 0 then vertex is a minimum

• If a < 0 then vertex is a maximum

Here a = - 7 < 0 , thus

(- 8, 3 ) is a maximum

Step-by-step explanation:

Answer:

The steps are more or less the same, except for one new addition:

1. Divide the tens column dividend by the divisor.

2. Multiply the divisor by the quotient in the tens place column.

3. Subtract the product from the divisor.

4. Bring down the dividend in the one's column and repeat it.

m<B=20

m<ACB=110

m<ACD=70

Answer:

You can't divide two fractions together, so you multiply the second fraction by taking its reciprocal.

[tex]\frac{3}{5} * \frac{2}{1} \\\\= \frac{6}{5}[/tex]

If we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].

Given that,

So, the decreased fraction should be

[tex]= \frac{3}{5} \times \frac{2}{1} \\\\= \frac{6}{5}[/tex]

Therefore we can conclude that if we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].

Answer:

8 over 15

Step-by-step explanation:

you should get a calculator.

Answer:

8/15

Step-by-step explanation:

After 3 months, there will be 12 of each type of caregiver

An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.

Since the daycare center in Seaside currently has 9 assistant caregivers and 6 senior caregivers. Since demand is high, the owner is going to be hiring 1 assistant caregiver per month and 2 senior caregivers per month.

This will be:

9 + m = 6 + 2m

where m= number of months

Collect the like terms

2m - m = 9 - 6

m = 3

The number of caregiver will be:

9 + m

9 + 3

= 12

Answer:

First question: a

Second: d

Third: b

Fourth: a

Fifth: a

Sixth: b

Step-by-step explanation:

Ask me if you need an explanation for any of the questions because there isn't much to explain for rounding.

Fifth: The reason that the answer is not b is because the 6 in that equation should have a - (if it was a typo, the answer should be b)

Similar figures are the same shape but not the same size. you can find out the scale by using parallel lines.

Answer:

*You could just look it up.

Here's what I found on google:

Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent, and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.

So basically, similar figures are 2 figures that are the same shape.

They don't have to be the same size.
