Answer:

A.$6.44

B.$8.05

Step-by-step explanation:

A.$6.90/15%=$0.46-$6.90=$6.44

B.$6.44*25%=$1.61+$6.44=$8.05

Answer:

answer for 6.90/15%= 6

answer for 25%= 7.5

Step-by-step explanation: These are answer is all correct there are no mistakes

Answer:

Step-by-step explanation:

∠A + ∠B = 180

where ∠A = 6x - 18

           ∠B = 14x + 38

first step is to solve for x:

6x - 18 + 14x + 38 = 180

6x + 14x = 180 + 18 - 38

20x = 160

x = 160 / 20

x = 8

now substitute x=8 into angle A

∠A = 6x - 18

∠A = 6(8) - 18

∠A = 30°

Answer:

x = 8

Step-by-step explanation:

Given

- 2(- 3x + 3) + 2x = 58 ← distribute and simplify left side

6x - 6 + 2x = 58

8x - 6 = 58 ( add 6 to both sides )

8x = 64 ( divide both sides by 8 )

x = 8

Answer:

D

Step-by-step explanation:

Answer:

Hey buddy, here is your answer. Hope it helps you.

Step-by-step explanation:

1. 0.008

2. Square root of 64 is 8 and cube root of 64 is 4. The difference is 4.

3. Area=100 sq.cm. The side is 10 cm. so the perimeter is 4 x Side= 4x10=40 cm.

4. the two square roots of 25 are 5 and 5. Cuz 5 and 5 gives 25.

Answer:

4.116 × 108

Step-by-step explanation:

I simply used a Scientific Notation Converter

Answer:

The answer would be 4.116 x 10 exponent of 8

Step-by-step explanation:

In scientific notation, the answer has to be between 1-10, so to make this number between one and ten, you must create a decimal behind the number in the one's place and move it until you get to the first number (in this case, you would move it eight times, so your equation would be 4.116 x 10 to the eight power (exponent of eight). If you need to round the number to the tenth place, it's 4.1 x 10^8

Hope this helps!

Answer:

Always true

Step-by-step explanation:

Here, we want to evaluate if the given statement is true

The discriminant D can be calculated using the formula;

b^2 - 4ac

if D is greater than 0, then we will have only real roots

In a case where a and c are of opposite signs;

then -4ac will always give a positive value which can be added to b^2

This positive value will ensure that D is greater than zero and hence we can have only real roots

So this assertion is always true if a and c are of opposite signs

Answer:

22w + 115 = 325           w = about 10 weeks

Step-by-step explanation:

The first part of this inequaltiy is 22w. Since he/she will set aside $22 a week, you would put a variable because the number of weeks you will need to set aside $22 is unknown therefore you put a variable that makes sense. I put w because you can say that w=weeks. The next part of the inequality is adding $115 because he/she has already saved $115 so we add that to 22w. Finally 22w+115 has to equal $325 because that is how much the necklace costs. Hope this helps!
