Given ∠2 and ∠4 are vertical angles.
Prove ∠2 ≅ ∠4

Answer:

3.8 × 10^{1}

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.

Follow the steps below to see how 38 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 38

New Number: 3.8

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 3 . 8

Decimal Count: 1

There are 1 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 3.8

b = 1

Now the whole thing:

3.8 x 10^{1}

Step 4

Check work:

10^{1} = 10 x 3.8 = 38

Greetings from Brasil...

Exponential equation - objective: to make the bases of the 1st and 2nd members equal

24 = 3 · 2ˣ    let's move from 3 to the 1st member

24 ÷ 3 = 2ˣ

8 = 2ˣ     simplifying 8: 8 = 2³

2³ = 2ˣ    as the bases are the same, we work only with exponents

Answer:

Step-by-step explanation:

Given the weekly revenue and cost function

R(d) = 12000

C (d) = 350d + 5000

A firm break even point occurs when the amount of revenue is equal to the cost.

If the company Bridal solution breaks even then C(d) = R(d)

350d + 5000 = 12000

350d = 12000 - 5000

350d = 7000

divide both sides by 350

350d/350 = 7000/350

d = 20

Hence the total number of wedding dressing to be sold by Bridal Solutions for them to break even is 20 dresses.

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-6, -5) and (2, 0)

The distance is

[tex]d = \sqrt{ ({ - 6 - 2})^{2} + ({ - 5 - 0})^{2} } \\ = \sqrt{ ({ - 4})^{2} + ({ - 5})^{2} } \\ = \sqrt{16 + 25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

We have the final answer as

[tex] \sqrt{41} \: \: or \: \: \: 6.403 \: \: \: units[/tex]

Answer:

It D: 8x=64

Answer:

D: 8x = 64

Step-by-step explanation:

($8) equals the amount he makes for washing 1 car

($64) is the total amount Zane has made from washing cars

(X) is equal to how many cars he has washed for the total to be $64

Now, all we have to do is write down an equation that shows how we can find how many cars have been washed for him to get his sum of $64.

8 times x (x is equal to the number of cars he's washed) so 8 times something (or x) gives you the amount of money Zane has made which would be the only viable answer to the question.

8 - x = 64 - Incorrect

You would not be subtracting the amount of cars Zane has washed by the amount of money he is making per car.

64x = 8 - incorrect

This would mean you're multiplying the total amount of money Zane has made, by how many cars he's washed, which then equals the amount he makes per car. Doesn't make sense ik.

8 + x = 64 - incorrect

While this could look like a viable answer to what they're asking, don't be tricked. You have to multiply the number of cars Zane has washed by the amount he makes per car, otherwise you would just be adding 8 plus the number of cars he washed which does not equal $64.

Hope this helped:)

Answer:

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable

Answer:

1.5 ounces

Step-by-step explain:

for every 3 ounces of juice, 2 ounces of water is needed.

therefore, 3/2 = 1.5 ounces

See the images attached

I'll solve one from each kind

Q1)

6 = a/4 + 2 (mutiply both sides)

24 = a + 8 (move the terms)

-a = 8 - 24 (calculate)

-a = 8 - 16 (change the signs)

a = 16

Q8)

2( 2 + 5) = -2 (divide both sides)

n + 5 = -1 (move the constant to the right)

n = -1 - 5 (calculate)

n= -6

Q3)

9x - 7 = 7 (cancel equal terms)

9x = 0 (divide both sides)

x = 0

Answer:

x=10

Step-by-step explanation:

(2x)/(x-5)=4

first you multiply the denominator on both sides

2x=4(x-5)

then multiply

2x=4x-20

then move all the x variables to one side and the constants to the other with subtraction and addition

20=2x

divide and you get x=10

you can plug this in to check your work and you'll see: (2(10))/(10-5)=4 or 20/5=4 which you know is true

Answer:

a = -9

Step-by-step explanation:

8 - a = 17

8 -17 = a

-9 = a

Answer:

-9

Step-by-step explanation:

subtract 8 from both sides. divide -1 by both sides it gives you -9. When put into the equation the two negatives make a positive and you add 8 + 9 which gives u 17.

Answer:

If boys to girls, 5:8. If girls to boys, 8:5.

Step-by-step explanation:

There are 8 girls and 5 boys. That means the ratio could be 8:5 or 5:8. You didn't specify in the question which one, so I can't tell you which one. But, if the question asks for boys to girls, put 5:8. If it asks for girls to boys, but 8:5.

Answer:

m∠B= 67

m∠C= 23

Step-by-step explanation:

okay so same thing we did before except they will equal 90 not 180

B= 3(c)+2

c+b=90

c+3(c)+2=90

4c+2=90

4c=92

c=23

now input them! or subtract!

90-23=67

m∠C=23

m∠B=67
