Answer:

B

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: 7200

Step-by-step explanation: the formulae is w times l times h. So you just multiply them all together. 24x15x20= 7200

Answer: the Prime Factors of 1512 are: 2, 2, 2, 3, 3, 3, 7.

Step-by-step explanation:

Given:

1 mile = 5280 feet

1 meter = 3.3 feet

convert 60 miles per hour to meters per second

60 miles to meters

60 miles x 5280ft x 1meter = (60*5280m)/3.3 = 316800m/3.3

                 1 mile    3.3ft

= 96,000 meters

1 hour to seconds

1 hour x 60 minutes x 60 seconds =   1 * 60 * 60sec = 3600 seconds

               1 hour            1 minute

unit rate: meters per second

96000 meters ÷ 3600 seconds = 26 2400/3600

simplify 26 2400/3600 ⇒ 26 2/3 meters per second

2400 ÷ 1200 = 2

3600 ÷ 1200 = 3

Answer:

Answer:

No it is equal to -39

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

1+4(3x+10)-12x

1+12x+40-12x --> distribute

41+0x --> add like terms

1+4(3x+10)-12x = 41 not -9

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.

Step-by-step explanation:

I did have an explanation here but someone *cough* *cough* laurenercsp6fpli  deleted all my answers for no reason. But I did the math and I assure you that the answer is correct.

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

1. idk

write 3x as a difference

x^2+4x-x-4>0

then factor out x from the expression

X x (x+4)-x-4>0

factor the negative sign

X x (x+4)- (x+4)>0

( x+4)x (x-1)>0

aneswer: (-∞ , -4) ( 1, + ∞)

Answer:

The fisherman row 14 mph

Step-by-step explanation:

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:

10 square units

Step-by-step explanation:

Because to get the area of a triangle you cut the base length in half then multiply it by the height, in this case 2.5*4 = 10 square units

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:

∠ABC = 32°

Step-by-step explanation:

Given that the measure of the supplement of ∠BAC is (18x+22) degrees.

so

∠ABC +  (18x + 22)° =180°

∠ABC +  18x  =180°-22°

∠ABC +  18x  =158°

∠ABC = 158° - 18x ----[Equation A]

Given that the measure of the complement of ∠BAC is (9x-5) degrees.

so

∠ABC +  (9x-5)° =90°

∠ABC +  9x  =90°+5°

∠ABC +  9x  =95°

∠ABC = 95° - 9x ----[Equation B]

Equating [Equation A] and [Equation B]

158° - 18x = 95° - 9x

-18x+9x = 95° - 158°

-9x = -63

divide both sides by -9

x = 7

Now, substituting the value x=7 in the [Equation A]

∠ABC = 158° - 18(7)

          = 158° - 126°

          = 32°

Thus,

∠ABC = 32°

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 :)
