Answer:

1:21

Step-by-step explanation:

Easiest trick way to do this is do 26/546 on your calculator (if you got a scientific one) this would simplify this to its lowest fraction which can be converted into a ratio in this case the ratio of teachers to students is 1:21

What goes outside during division with fractions? The numerator, or the denominator?

Ymorist [56]

Answer:

Denominator

Step-by-step explanation:

Think of it this way - numerator/denominator = nana/dog

Nana goes inside to the bathroom, but the dog goes outside to do its thing

If it was the other way around, it wouldn't be very pleasant.

LOL

Anyway, I hope this was helpful

Answer:

$15x + 30y - 220$

Step-by-step explanation:

$(30 \times \frac{1}{2} x ) + (30 \times - 2) + (40 \times \frac{3}{4} y )+( 40 \times - 4)$

$= 15x - 60 + 30y - 160$

$= 15x + 30y - 60 - 160 \\ = 15x + 30y - 220$

I need help finding the value of x n y. thank you

rewona [7]

Step-by-step explanation:

Here with reference angle 45°

Hypotenuse ( h) = y

Perpendicular (p) = x

base (b) = 5√2

We know

tan 45° = p/b

1 = x / 5√2

Therefore x = 5√2

Now

h = √(5√2)^2 + 5√2)^2

= √ 50 +50

= √100

= 10

Hope it helped

Janae solved the equation 3.67 = c − 2.13 , and found the value for c. Janae's solution was c =1.54 Do you agree or disagree wit

zysi [14]

Answer:

The correct answer is 5.8

Step-by-step explanation:

Janae did not read the minus/negative sign correctly. She subtracted instead of added, meaning she did not isolate her c.

3.67=c-2.13

+2.13 +2.13

5.8=c

Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul

Setler79 [48]

The A option is correct.

<h2>Ratio and proportion</h2>

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

The interest rate applied to the present value has on the monthly payment P in the formula

$\rm P = PV(\dfrac{i}{1-i})^{-n}$

The effect an increase in i.

$\rm P = PV(\dfrac{i}{1-i})^{-n}\\$

on simplifying the equation, we get

$\rm P = PV(\dfrac{i}{1-i})^{-n}\\\\P = PV\dfrac{1}{(\frac{i}{1-i})^n}\\\\\\P = PV(\dfrac{1-i}{i})^{n}\\\\P = PV(\dfrac{1}{i} - 1)^{n}$

Let n be the constant, then the equation will be

$\rm P = PV(\dfrac{1}{i} - 1)^{n}\\\\\dfrac{1}{V} \propto \dfrac{1}{i}\\\\V \propto i$

It is clear that V is proportional to i.

An increase in i, the interest rate, will not change P, the monthly payment.

Thus, the A option is correct.

More about the ratio and the proportion link is given below.
