x=3.542

Answer:

X= 1

Step-by-step explanation:

6.05x-12.5=48 Add 12.5 to both side

         +12.5 +12.5

6.05x = 60.5 now divide both sides by 6.05

/ 6.05    /60.5

Step-by-step explanation:

Answer:12B - 12M = 36

12B + 15M = 63

Subtract one from the other:

12B + 15M = 63

-(12B - 12M = 36

-------------------------

0 + 27M = 27

27M = 27

M = 1

B - M = 3 (from the original equations)

B - 1 = 3

B = 4

Answer:

B: u = (1,5) and v = (-5,1)

Step-by-step explanation:

edge 2021

The pair of vectors which are orthogonal to each other will be u = ⟨1, 5⟩ and v = ⟨–5, 1⟩. Then the correct option is B.

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

For the orthogonal vector, the dot product of two vectors will be zero.

Check first option, we have

u·v = ⟨–3, 2⟩·⟨–2, 1⟩

u·v = 6 + 2 = 8 (incorrect)

Check second option, we have

u·v = ⟨1, 5⟩·⟨–5, 1⟩

u·v = –5 + 5 = 0 (correct)

Check third option, we have

u·v = ⟨2, 1⟩·⟨–4, 3⟩

u·v = –8 + 3 = –5 (incorrect)

Check fourth option, we have

u·v = ⟨2, 3⟩·⟨3, 1⟩

u·v = 6 + 3 = 9 (incorrect)

Then the correct option is B.

Yes and no

Step-by-step explanation:

I say yes and no because I think that their relationship throughout the show could spread to a romance rather than a bromance. I love this ship, although I do also love the cannon ships. Hinata x Naruto and Sakura x Sasuke. And I know a lot of people hate Sasuke and Sakura ship but you know that song that goes, "I hate everything about you! Why do I love you?!?" That is what I think of that ship and I love it.

Answer:

k = 23% profit on sale price is needed to ensure 30% profit on cost price

Step-by-step explanation:

Let sale price be = s , Profit = k% of s

Let cost price be = 100 , Profit = 30% of c

Cost price (c) + profit (p)  = Sale price (s)

c + 0.3c = s

1.3c = s

Profit as a percentage of sale = (Profit / Sale) x 100

= (0.3c / 1.3c) x 100

= 23%

Answer:$72.00

Answer:

600.3

Step-by-step explanation:

600.3

The total sale was $2000.

Percentages are fractions that are counted out of 100. The number is followed by this symbol: %. A percentage of an object is how many parts of it there are out of 100 equal parts

Given that, You earn 30% commissions on the sales of your new app, you earn $600 in commissions,

Let the total sales be x,

Therefore, according to the question,

30% of x = 600

x × 30/100 = 600

x = 600 × 100/30

x = 2000

Hence, the total sale was $2000.

Answer:

Total amount of money (including interest) = $ 1417

Step-by-step explanation:

Total amount = 545 × [tex]\frac{100+4}{100}[/tex] × 2.5

                      = 1417

To find interest only, minus 545 from 1417 :)

Answer:

Press A takes 10 hours to do a certain job. So Press A does (1/10)th of the job in an hour.

Press A and Press B, together do (1/2.5) or (4/10)th of the job in an hour.

So Press B does (4/10)-(1/10) = (3/10)th of the job in an hour. So Press B can do the job in (10/3) hours or 3 hour and 20 mins.

Check: A does (1/10)th and B does (3/10)th part of the job in an hour. A and B together will take (1/10)+(3/10) = 4/10th of the job in an hour. So they will complete the job in 10/4 = 2.5 hours. Correct.

Answer: Press B can do the job in 3 hour and 20 mins.

Answer:

570 grams of water

Step-by-step explanation:

171 divided by 6 = 28.5

28.5 grams are in 1 ounce

so Multiply 28.5 by 20 to get the new amout which is 570

The amount of water present in 20 ounces of grapefruit juice will be 570 grams.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

A 6-ounce serving of grapefruit juice contains 171 grams of water.

The ratio of the amount of grapefruit and water present will remain constant.

Let 'x' be the amount of water present. Then the equation is given as,

x / 20 = 171 / 6

x = 20 · 171 / 6

x = 570 grams

The amount of water present in 20 ounces of grapefruit juice will be 570 grams.
