9 mugs for $45

What is the rate?

And what is the unit rate?

Answers

Answer:  The unit rate is $5 per  mug.

Step-by-step explanation:

To find the the unit rate, you will find the amount  one mug will cost.

If there are 9 mugs  then to get it to one, you will have to divide 9 by 9, and the same way you will have to divide 45 by 9.

45 / 9 = 5  

-10(-1/2y+(-7/2)+7y=-25

Answers

Answer:

y = -5

Step-by-step explanation:

-10(-1/2y + (-7/2)) + 7y = -25

Let's first of all expand the bracket to get;

5y + 35 + 7y = -25

12y + 35 = -25

12y = -25 - 35

12y = -60

y = -60/12

y = -5

The value of p and q in the right triangle are as follows:

p ≈ 30.6 units

q ≈ 14.9 units

How to find the side of a right triangle?

A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the side of a right triangle can be found using trigonometric ratios as follows:

Let's find p and q using the trigonometric ratios.

Hence,

sin 64 = opposite / hypotenuse

opposite side = p

hypotenuse = 34

Therefore,

sin 64 = p / 34

cross multiply

p = 34 sin 64

p = 30.5589975742

p ≈ 30.6 units

Hence,

cos 64 = adjacent  / hypotenuse

cos 64 = q / 34

cross multiply

q = 34 cos 64

q = 14.9046189908

q = 14.9 units

Therefore,

p ≈ 30.6 units

q ≈ 14.9 units

Al, Bert, and Rob determined that the sum of their ages is 62. Bert is twice as old as Rob, who is 10 years older than Al. How old is each?

Answers

Answer: AI is 8, Rob is 18, and Bert is 36

Step-by-step explanation:

Ok, so the sum of their age is 62. Bert is x2 of Rob. Also someone is 10 years older than AI, lets assume Rob is the guy that is 10 years older. x+y+10+(z times 2)=62. So lets solve it. 62-10=52. 52=x+y+(z times 2). Now if you think about it x and y is the same, because the 10 is already minused. So it's now x*2+z*2=52, if you assume it now, z is x+10. So now it is 52=x*2+(x+10)x2. Now we break out the brackets so its x*2+x*2+20=52. Lets simplify it. x*4+20=52, lets swift the 20 the the other side. x*4=52-20, x*4=32. 32/4=8 so 8 is x. Now we know AI is 8, Rob is 18, and Bert is 36!

Una fábrica de bolígrafos fabrica sus propios productos en tres colores distintos. 25 de su fabricación son bolígrafos azules, 13 son bolígrafos negros y el resto son bolígrafos rojos. a.- ¿Qué fracción de bolígrafos son bolígrafos rojos? b.- Si en total en un día se han fabricado 2250 bolígrafos ¿ Cuántos se han fabricado de cada color?

Answers

Answer:

a) 4/15

b) 900 bolígrafos azules

750 bolígrafos negros

600 bolígrafos rojos

Step-by-step explanation:

Una fábrica de bolígrafos fabrica sus propios productos en tres colores diferentes. 2/5 de su fabricación son bolígrafos azules, 1/3 son bolígrafos negros y el resto son bolígrafos rojos.

a) ¿Qué fracción de bolígrafos son bolígrafos rojos?

Deje que el número total de bolígrafos se represente como 1

La fracción de bolígrafos rojos =

1 - (Fracción de bolígrafos azules + Fracción de bolígrafos negros)

= 1 - (2/5 + 1/3)

El mínimo común denominador es 15

= 1 - (6 + 5/15)

= 1 - 15/11

= 4/15

Por lo tanto, la fracción de bolígrafos rojos = 4/15

b) Si se han fabricado un total de 2250 bolígrafos en un día, ¿cuántos se han fabricado de cada color?

Para bolígrafos azules

2/5 de su fabricación son bolígrafos azules,

= 2/5 × 2250 bolígrafos

= 900 bolígrafos azules

Para bolígrafos negros

1/3 son bolígrafos negros

= 1/3 × 2250 bolígrafos

= 750 bolígrafos negros

Para bolígrafos rojos

4/15 son bolígrafos rojos

= 4/15 × 2250 bolígrafos

= 600 bolígrafos rojos

Cathy is making bows from a ribbon that is 11 1/5 yards long. She needs to cut the ribbon into equal pieces that measure 2/5 yard to make each bow. How many bows can Cathy make? Sam solved the problem below but got it incorrect. Explain Sam's error.

Answers

Answer:

28 bows

Step-by-step explanation:

Each bow is an equal piece.

1 bow = 2/5 yard

Total yard of ribbon = 11 1/5 yards

Hence:

2/5 yard = 1 bow

11 1/5 yards = x

2/5x = 11 1/5

x = 11 1/5 ÷ 2/5

x = 56/5 ÷ 2/5

x = 56/5 × 5/2

x = 28 bows

Therefore, Cathy can make 28 bows
