Leda is grouping 895 dimes into rolls of 10 dimes. How many rolls will she have? How many extra dimes will there be?

A. 8 rolls, 5 extra dimes

B. 40 rolls, 5 extra dimes

C. 89 rolls, 5 extra dimes

D. 800 rolls, 9 extra dimes

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:

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°

Answer:

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:

-6x^2 - 7x +1

Step-by-step explanation:

2x^2+3x-9  -(8x^2+10x-10)

3x^2+3x-9 -8x^2-10x+10

Combine like terms

-6x^2 - 7x +1

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

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: it is -1

Step-by-step explanation:

I just finished the test

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.
