Answer:

B and E

Step-by-step explanation:

B. You subtract the & $120 from $280, then divide the sum by 3.5 hours you’ll get $45.71

E.you subtract the $100 from $180 and divide it by 2 hours you get $40

Bill's Plumbing charged $180 for a 2-hour job. This includes a $100 fee to come to the house

Tyrese's Plumbing charged $280 for a 3.5-hour job. This includes a $120 fee to come to the house

From the given question, we need to determine the plumber that costs less than $50 per hour.

Step-by-step explanation:

8x + y = -16

y = -8x - 16 --(1)

-3x + y = -5 --(2)

sub (1) into (2):

-3x - 8x - 16 = -5

-11x = 11

x = -1

sub x = -1 into (1):

y = -8(-1) - 16

y = -8

therefore, the solution is (-1, -8).

7. Sorry, I couldn't figure out how to solve this question :(

Step-by-step explanation:

Since I'll be using a similar method to solve these questions, I won't go into a detailed explanation for how I solved every single question. If you do need extra help, please ask in the comments below my answer.

1. Let's use part (a) as an example. The ratio is 3:10. To new ratio is ?:40. So, 10 becomes 40. What number multiplied by 10 equals 40? The answer is 4. If 10 is multiplied by 4, then 3 must be multiplied by 4 as well. 3*4 = 12, so the ratio is 12:40.

In part b the ratio is multiplied by 3, part c is 4, and part d is 1/2.

2. To solve this, add the values on both sides of the ratio together: 2 + 5 = 7. Now, divide the total number of pupils, 140, by 7: 140/7 = 20. Finally, multiply 20 by both sides of the ratio: 2 * 20:5 * 20 = 40:100. There are 40 boys and 100 girls.

3. To solve this I used the same method as the one I used in question 1.

4. The ratio is 5:140, where 140 becomes 2000. To solve, use the method used in question 1.

5. Simplifying ratios is the same as simplifying fractions. Find the greatest common factor of the values on both sides of the ratio and divide both sides by that factor. For example, in part a the factor for 45:20 is 5. 45/5 = 9 and 20/5 = 4. The ratio becomes 9:4.

For part b the factor is 9 and for part c the factor is 50.

6. Same method as was used in question 2.

Hope this helps :)

Answer:  B . y =  5/6x  + 7  

Step-by-step explanation:

5x - 6y = - 42     To write it in slope intercept form, we need to solve for y.

-5x            -5x       Subtract  5x from both sides

    -6y = -5x - 42       Divide both sides by -6

   y =  5/6x  + 7

Answer:

(g-3)(g+3)

Step-by-step explanation:

this is a difference of squares equation so you have to find two numbers that multiply to make c (-6) and add together to make b (0)

-3 and 3 add together to make 0 and multiply to make -6

Answer/Step-by-step explanation:

A. Given that ∆A has side lengths 3, 4, and 5, that corresponds to the side lengths 6, 7, and 8 of ∆B, both ∆s can only be similar to each other if the ratios of their corresponding side lengths are equal.

Thus:

[tex] \frac{3}{6} [/tex] ≠ [tex] \frac{4}{7} [/tex] ≠ [tex] \frac{5}{8} [/tex] .

✅The ratio of their corresponding side lengths is not equal, therefore, triangle B is not similar to triangle A.

B. To get the possible side lengths for triangle B to make it similar to triangle A, simply multiply each side length of triangle A by a scale factor.

Let's use a scale factor of 2.

3 × 2 = 6

4 × 2 = 8

5 × 2 = 10.

✅Possible side lengths for triangle B that will make it similar to triangle A are: 6, 8, and 10.

downstream means to subtract so you subtract 6-4 which will gives you 2 then you multiply 2 times 7 which is 14 because it says hours.

Answer:

m∠1=77°

m∠2=36°

m∠3=30°

Step-by-step explanation:

First, find angle 1 by adding 66 and 37 and subtracting them from 180 because there are 180 degrees in an angle.

180-(66+37)=77°

You can then find angle 2 by finding the other angle not given. You can find this angle by subtracting 77 from 180, giving you 103. To find angle 2, add 103 and 41 and subtract them from 180.

180-(103+41)=36°

You can then find angle 3 by adding the angle 103 and the angle 47, and subtracting them from 180

180-(103+47)=30°

Step-by-step explanation:

Answer: See explanation

Step-by-step explanation:

A. Since each ornament requires 0.5 yards of velvet and Joseph wants to make 45 ornaments, the number of yards of velvet she must be buy will be:

= 45 × 0.5

= 22.5 yards

Since 1 yard = 3 feet

22.5 yards = 22.5 × 3 = 67.5 feet

B. If the felt costs 10 cents ($0.10) per foot, what is the total cost of the velvet in dollars.

Total Cost = 67.5 × $0.10 = $6.75

C. A manufacture is making 1,000 times as many ornaments as Joseph to sell in stores nationwide. The amount of yards needed will be:

= 1000(45 × 0.5)

Answer:

x = 4°

Step-by-step explanation:

According to exterior angle sum property , sum of two opposite interior angles of the triangle is equal to the exterior angle.

So, using exterior angle sum property :-

mBDC + mBCD = mWBC

=> 8x - 1 + 46° = 18x + 5

=> 18x - 8x = 46 - 1 - 5

=> 10x = 40

=> x = 4°
