Steph age is 7/5 times of the total of students in this class minus 22. If steph is 13 years old , write an equation to find the total students in the class.​

Answers

Step-by-step explanation:

Let us take:

Steph's age = x

No. of students in the class = y

Given that,

x = 13

also,

x = 7/5y - 22

That gives,

13 = 7/5y - 22

13 + 22 = 7/5y

35 = 7/5y

35 × 5/7 = y

5 × 5 = y

What is the product of 7×-6 1/8

Answers

Answer:

-42.875 or -42 7/8

Step-by-step explanation:

you can turn -6 1/8 into a decimal: -6.125 and multiply it with 7.

The product of the fraction 7 x -(6 1/8) is -42.875 or in fraction form -42 7/8.

We have expression: 7 x -(6 1/8).

First, write the mixed fraction into improper fraction as

Numerator = 8 x 6 + 1 = 49

Denominator = 8

Now, the product will be

7 x -(6 1/8)

= 7 x (-49/8)

= 7 x (-6.125)

= -42.875

m< AED = 16y + 10. Find the value of y so that ED I AB.

Answers

Full question attached:

Answer and explanation:

To calculate y in the equation <AED=16y+10 we first find the value of angle AED from the diagram(attached)

From the diagram, we can see that <AED = 180 degrees given that <AED is angle on a straight line=180 degrees.

The line AB is therefore perpendicular to line ED

Hence we calculate y in the equation <AED= 16y+10

180= 16y+10

180-10=16y

16y=170

y=170/16

y= 10.625

Step-by-step explanation:

dP/dt = 0.0013P (1 − P/6200)

Euler's method states:

yₙ₊₁ = yₙ + Δt F(tₙ, yₙ)

Substituting:

P(t+1) = P(t) + (1) [0.0013 P(t) (1 − P(t)/6200)]

P(t+1) = P(t) + 0.0013 P(t) (1 − P(t)/6200)

We know that when t=0, P=1000.

P(1) = P(0) + 0.0013 P(0) (1 − P(0)/6200)

P(1) = 1000 + 0.0013 (1000) (1 − 1000/6200)

P(1) = 1001.1

Repeating the pattern, we get P(50) is:

P(50) = 1055.7

Rounded to the nearest whole number, P(50) = 1056.

A percentage is a ratio or number that may be expressed as a fraction of 100. Moreover, it is denoted by the sign "%."

Given information:

Jose gets his hair cut for $12.

He gives his barber a 15% tip.

To calculate the tip, we need to find 15% of the cost of the haircut.

15% can be written as a decimal as 0.15.

So, the tip amount is:

0.15 x $12 = $1.80

Therefore, Jose gives the barber a $1.80 tip.
