Answer:

8.84×10⁻

Step-by-step explanation:

To write a number in standard form we need to write down a number between 1 and 10, then × 10(to the power of a number). Therefore, the standard form of 0.884 is ¹.8.84×10⁻.

Answer:

D. 70°

Step-by-step explanation:

Because Measure of central angle is equal to the measure of its corresponding minor arc.

Therefore, measures of indicated angle is 70°

Answer:

C

Step-by-step explanation:

To solve this problem, we need to first find the ratio of numbers less than four to total numbers.

There are 3 numbers on the wheel less than 4 (1, 2, and 3). There are 8 total numbers, meaning the ratio of numbers less than 4 to total numbers is 3:8.

Now, we need to find the probability of spinning a white number. There are 3 white numbers on the wheel (3, 5, 8). However, one of these numbers (3) is less than 4, so it is already accounted for in the previous ratio. There are 2 numbers left, meaning the ratio of remaining white numbers to total numbers is 2:8.

Adding this to the original equation, we get 5:8. As a fraction, 5:8 = 5/8. The answer that correctly highlights this is C.

I believe the answer is b= -5

Answer:

b=-5

Step-by-step explanation:

3b+2-6b=32+5b-2b(first you should collect like terms on each side.) so

3b-6b+2=32+5b-2b (lessen thing by both sides.)

-3b+2=32+3b (then you collect terms to one side)

-3b-3b=32-2

-6b=30 (you divide both sides by 6)

-b=5 (since b cannot be a negative u divide both sides by -1)

so..b=-5

Feet × feet × feet = cubic feet. Ft^3

Answer:

[tex]16^{3x}= 32^{2(x+2)}[/tex]exponential equation represents this situation

Step-by-step explanation:

Let the number be x

Raising 16 to a power that is 3 times some number=[tex]16^{3x}[/tex]

Raising 32 to twice the sum of the number and 2 =[tex]32^{2(x+2)}[/tex]

We are given that Raising 16 to a power that is 3 times some number is the same as raising 32 to twice the sum of the number and 2.

Equation:[tex]16^{3x}= 32^{2(x+2)}[/tex]

So, The required equation is[tex]16^{3x}= 32^{2(x+2)}[/tex]

Hence  [tex]16^{3x}= 32^{2(x+2)}[/tex]exponential equation represents this situation

Answer:

hi! id say your answer should be B. DF/FB=EG/GC

Step-by-step explanation:

Your question was if FB is parallel to BC, what must be true? A. and C. are not necessarily connected to FB and BC and do not prove that those two lines are parallel. while B. DF/FB = EG/GC does prove that they are parallel because the lines mentioned in the question, FG and BC, are attatched by the lines that are provided by answer B. I hope this helps!

The necessary equation which is true for the  given triangle is:

[tex]\frac{AD}{AB} = \frac{AE}{AC}[/tex]

Similar triangles are those with the same form but different sizes. Examples of related objects are all equilateral triangles and squares with any side length. In other words, two triangles that are comparable have corresponding sides that are proportionately equal and corresponding angles that are congruent. The symbol "≈" above illustrates how the triangle looks similar.

Given that,

A right triangle ABC,

which contains two segments DE & FG

So according to properties of similar triangles, the ratio of length of the sides of the triangle is equal,

AB/AC  = AD/AE

it can be further simplified as

AB/AD = AC/AE

Therefore, the equation is AB/AD = AC/AE

Answer:

352

Step-by-step explanatioThe shape as you can see is a trapezoid. To find the area of the trapezoid is base 1 + base 2 x height. I multiplied 26 and 16 which made the whole shape 416. Now, we need to take away the white triangle which will show in the end the area of the shaded figure. To find the area of the triangle, you need to do 8x16 then divide by 2. 8 x 16= 128 feet. Then we divide that number by two which equals 64. The area of the unshaded triangle is 64 feet. Finally, we take 416 and subtact 64, which equals 352.

Good luck on your assignment

Answer:

#1: 1) Buying a pack of 3

#2: 2) Jim

#3: 2) 65

#4: 1) $0.04 per fluid ounce

Step-by-step explanation:

#1:

5 shirts for $26.25; divide $26.25 by 5 to get the individual shirt which is $5.25

3 shirts for $14.25; divide $14.25 by 3 to get the individual shirt which is $4.75

10 shirts for $52.25; divide $52.25 by 10 to get the individual shirt which is $5.225 ($5.23).

The cheapest individual shirt is the 3 shirt package.

#2:

Dwight: 3 tickets for $191; divide $191 by 3 to get the individual ticket cost which is $63.67 (Rounded to the nearest hundredth)

Jim: 5 tickets for $309; divide $309 by 5 to get the individual ticket cost which is $61.80

Pam: 7 tickets for $435; divide $435 by 7 to get the individual ticket cost which is $62.14 ( Rounded to the nearest hundredth

Andy: 4 tickets for $256; divide $256 by 4 to get the individual ticket cost which is $64.00

The one who paid the lowest price per ticket is Jim.

#3:

91 portraits in 7 weeks

? portraits in 5 weeks

By cross multiplying, we get 455 portraits in 7weeks*?

To find the unknown, we divide 7 by both sides, leaving the unknown by itself.

[tex]\frac{455}{7}[/tex] = ?

? = 65 portraits

#4:

2-quart bottle for $2.56

1 quart is equal to 32 ounces

Since we know that the bottle cost $2.56, we can divide the cost with the amount of ounces it needs, like the following: $2.56 divided by 64 ounces.

Why 64? The bottle of juice is 2-quarts, so we multiply 32 ounces by 2 to get 64 ounces.

The answer should be $0.04 per fluid ounce.

Step-by-step explanation:

Answer:The answer is 70 π

Answer:

A

Step-by-step explanation:

because if you divied 100 by 400 it is a lot less than the others

The expression that has the least value when x is 400 would be 10/x.

A linear equation is an equation in which the highest power of the given variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.

A. 100/x

100 / 400 = 0.25

B. 10/x

10/ 400 = 0.025

C. 100-x

100 - 400 = - 300

D. 10-x

10 - 400 = -390

Thus, the least value is o.o25.

Answer:

y = 22

Step-by-step explanation:

1/4 (y + 6) + 5 = 1/3 (4y - 1) - 17

1/4y + 6/4 + 5 = 4/3y - 1/3 - 17

1/4y - 4/3y = - 1/3 - 17 - 6/4 - 5

3/12y - 16/12y = - 4/12 - 17 - 18/12 - 5

- 13/12y = - 22/12 - 22

- 13/12y = - 22/12 - 22/1

- 13/12y = - 22/12 - 264/12

- 13/12y = - 286/12

- y = - 286/12 / 13/12

- y = - 286/12 * 12/13

- y = - 286/1 * 1/13

- y = - 286/13

y = 286/13

y = 22

The first thing you need to do, is add the total of all of the marbles together.

9 + 8 + 11 + 12 = 40.

Knowing this, you can take the amount of white marbles, (0) and put this against the 40 total marbles.

Since there are 0 white marbles in the jar, you know that it is impossible to pull one out of the jar.

0%

Answer: The answer is 0, because there is 0 white marbles in the jar to begin with.

Answer: (0, 0)

Step-by-step explanation:

We have the linear system:

y = r*x

y = s*x

We want to find the point where the lines intersect,

We know that

r*x = y = s*x

r*x = s*x

if r and s are different numbers (if r = s, this means that the two lines are the same line)

Then we have that the equality is only true when x = 0.

this means that the value of y is.

y = s*0 = r*0 = 0

So the point (x, y) where the lines intersect is (0, 0)

Answer:

Radius = 2cm

Step-by-step explanation:

We reverse equation for volume

V=πr2  h/3 becomes r2=  V/( h* 3 *π)

We have height of  6cm  so 6*3 = 18 Then V = 72/18π = 4

We then found the square r2 or ^2 or ^2 they are both same answers Radius = 2   as √4 = 2 and 4/2 also is 2

This radius is squared so we use the root √4cm and find r = 2.
