A = π r l + B

r is the radius, 3 cm here.

l is the slant height, the hypotenuse of a right triangle with legs 3 and 4 so

l = 5 cm

B is the area of the base, π r² of course.

A = π r l + B

A = π (3)(5) + π(3²) = 15π + 9π = 24π

Answer: 24 ( × π sq cm )

To make a specific hair dye, a hair stylist uses a ratio of 1 1/8 ounces of red tone, 3/4 ounces of gray tone, and 5/8 ounces of

natima [27]

Answer: To make 20 ounces of dye, we need 3 oz red tone, 6 oz of gray tone and 5 oz of brown tone.

To make 100 ounces of dye, we need 15 oz red tone, 30 oz of gray tone and 25 oz of brown tone.

Step-by-step explanation:

The amount of specific hair dye made by given ingredients= $1\frac{1}{8}+\frac{3}{4}+\frac{5}{8}$

$=\frac{9}{8}+\frac{3}{4}+\frac{5}{8}$

$=\frac{9+6+5}{8}=\frac{20}{8}=\frac{5}{2}\ oz$

Therefore , The amount of specific hair dye made by given ingredients= $\frac{5}{2}$ qz

Multiply reciprocal of $\frac{5}{2}$ to each ingredient to find the amount of each ingredient required to make 1 oz of specific hair dye.

To make 1 oz of specific dye, the amount of red tone needed $=\frac{3}{8}\times\frac{2}{5}=\frac{3}{20}\ oz$

Similarly, Gray tone= $\frac{3}{4}\times\frac{2}{5}=\frac{3}{10}\ oz$

Brown tone= $\frac{5}{8}\times\frac{2}{5}=\frac{1}{4}\ oz$

Now, multiply 20, to each

To make 20 oz of specific dye, the amount of red tone needed $=\frac{3}{20}\times20=3\ oz$

Similarly, Gray tone= $\frac{3}{10}\times20=6\ oz$

Brown tone= $\frac{1}{4}\times20=5\ oz$

To find each dye to make 100 ounces of dye, multiply 5 to the above amounts, [since $100=20\times5$ ]

To make 20 oz of specific dye, the amount of red tone needed $=15\ oz$

Similarly, Gray tone= $30\ oz$

Brown tone= $25\ oz$

It takes printer A 4 more minutes than printer B to print 40 pages. If working together, the two printers can print 50 pages in

Anastaziya [24]

Answer:

It will take printer A 24 minutes to print 80 pages.

Step-by-step explanation:

It takes printer A 4 more minutes than printer B to print 40 pages.

Let the time it takes printer B be x minutes, since printer A prints at 4 minutes more, it prints at (x + 4) minutes.

Printer A prints at the rate of (40/(x+4)) pages per minute.

Printer B prints at the rate of (40/x) pages per minute.

If working together, the two printers can print 50 pages in 6 minutes

They can print at the rate of 50 pages per 6 minutes, if working together.

Let us add these ratios, the

40/(x + 4) + 40/x = 50/6

Divide by 40

1/(x + 4) + 1/x = 5/24

(x + x + 4)/x(x + 4) = 5/24

2x + 4 = (5/24)(x² + 4x)

48x + 96 = 5x² + 20x

5x² - 28x - 96 = 0

Solving this using the quadratic formula,

x = [-b ± √(b² - 4ac)]/2a

a = 5, b = -28, and c = -96

x = [28 ± √(784 + 1920)]/10

= 28/10 ± √(2704)/10

= 28/10 ± 52/10

x = (28+52)/10 = 80/10 = 8

x = (28 - 52)/10 = -24/10 = -2.4

So, x is either 8 or -2.4

Since we are dealing with time, the realistic value is the positive value, x = 8, then we choose x = 8 minutes.

It takes printer A (x + 4) minutes to print 40 pages.

x + 4 = 12 minutes.

So, it takes it 12 minutes to print 40 pages.

Easily, it will take it twice as much time to print 80 pages.

So, it will take it 24 minutes to print 80 pages.

Anyone please answer me ,<br> Please solve this question

Mamont248 [21]

Answer:

Step-by-step explanation:

Multi-Inscribed Quadrilateral: 15

Bananas: 4

Clock: 3

Therefore, we can substitute for the last equation the values, so it would become:

3 + 4 + 4 x 15 = ?

First, we solve the multiplication according to PEMDAS.

4 x 15 = 60

Then, we can add from left to right.

3 + 4 + 60 = ?

3 + 4 = 7

7 + 60 = 67

Therefore, our answer would be 67.
