Answer:
5 yds
Step-by-step explanation:
i am assuming that 4 yd and 3 yd are the legs
so
to find the hypotenuse you square both legs add them and then take the square root of that
so
4^2 + 3^2 = c^2
16 + 9 = c^2
25 = c^2
c = 5
the final side is 5
A bicycle with 20 -inch diameter wheels is traveling at 13 mi/h. How many revolutions per minute do the wheels make?
The revolution per minute done by the wheel of a bicycle is 16.9 rev/min.
What is Velocity?Velocity is the rate at which a moving object's direction changes as perceived from a certain vantage point and measured by a particular unit of time. Kinematics, the area of special relativity that investigates how bodies move, starts with the fundamental idea of speed.
In order to be explained, the scientific vector quantity known as velocity needs to have both a magnitude and a direction.
As per the given information in the question,
Diameter of wheel = 20 inch
Radius, r = 10 inch
The velocity of the bicycle, v = 13 mi/h.
Revolution, R = v²/r
R = 13²/10
R = 16.9 rev/min

Kaleigh paid $37.45 for a calculator, after-tax, and the tax rate is 7%. What was the original cost of the calculator?
Step-by-step explanation:
that means that
$37.45 = 107%
as the price was 100% base price + 7% tax.
1% = 107%/107
100% = 1% × 100 = 107% × 100 / 107
so, the basic price (the "original cost") is
37.45 × 100/107 = $35.00

6. A recipe calls for 2 cups of milk for every 6 1/4 cups of flour. If you increase the flour to 43 3/4 cups, how many cups of milk will you use?
Step-by-step explanation:
5.
xnew = 205 = 2×xold + 5
200 = 2×xold
xold = 100
the old city machine can produce 100 copies per hour.
6.
2 cups of milk relate to 6 1/4 cups of flour.
such recipes represent a direct dependency of one variable on the other. one variable is always the other variable multiplied by a constant factor.
m = cups of milk
f = cups of flour
m = n×f
2 = n×(6 1/4) = n×(6×4 + 1)/4 = n×25/4
8 = 25n
n = 8/25
now, f = 43 3/4 = (43×4 + 3)/4 = 175/4
so,
m = 8/25 × 175/4 = (8×175)/(25×4) = 2×7 = 14
you will need 14 cups of milk.

What is factorization of expressions?
To factorize an algebraic statement, we first identify the terms' greatest common factors and then arrange the terms into groups in accordance with those groups. In plain English, factorization is the process through which an algebraic statement gets expanded in the opposite direction.
Not every term may share a factor in some algebraic formulas. For instance, have a look at the algebraic formula 12a + n -na - 12. There is no specific factor that unites the terms in this statement, yet the first and last terms share a factor of 12. The common factor between the second and third terms is n. Consequently, the terms can be rearranged as follows:
12a + n - na - 12= 12a - 12 + n - an
12a - 12 - a plus n = 12(a - 1) -n (a -1)
Following regrouping, each term's common component may be shown to be (a-1): 12a + n -na - 12=(a-1) (12 – n)

Step-by-step explanation:
step 1 of 2:
We got pairs: (-3, y) and (x, 2), to compute the missing x and y values, we plugin the number into the equation.
(-3, y)
y = -3x - 1
y = -3(-3) - 1
y = 9 - 1
y = 8
So we solve this pair as (-3, 8).

The values of the variables as represented in the right triangle are; (8√15)/3 and s = (4√15)/3.
What are the values of the variables in the given task content?It follows from the task content that the values of the variables in the right triangle are to be determined.
It follows from trigonometric ratios that;
Sin (∆) = opposite / hypothenuse
Cos (∆) = adjacent / hypothenuse

Find all x ∈ R that are solutions to this equation:
0 = ( 1- X- X^2-...) (2- X- X^2-...)
The solution of the geometric equation is x = 1/2 or x = 1
What is an equation?An equation is a mathematical expression that shows the relationship between variables.
What is a geometic series?A geometric series is the sum of a geometric sequence.
How to find the solution to the equation?Since the equation 0 = ( 1 - X - X²-...) (2 - X - X²-...). To solve this, let the series x + x² + ... = p
So, 0 = ( 1 - X - X²-...) (2 - X - X²-...).
0 = (1 - [X + X²+...) (2 - [X + X²+...).
Substitute x + x² + ... = p. So,
0 = (1 - [X + X²+...) (2 - [X + X²+...).
0 = (1 - p)(2 - p).
So, (1 - p) = 0 or (2 - p) = 0
p = 1 or p = 2
Since x + x² + ... = p, the left side of the equation is the sum to infinity of a geometric series.
What is the sum to infinity of a geometric series?The sum to infinity of the geometric series is given by
S = a/(1 - r) where
a = first term and r = common ratioFor the given series,
a = x and r = xSo, S = a/(1 - r)
= x/(1 - x)
Since S = p, we have that
x/(1 - x) = 1 or x/(1 - x) = 2
So, x = 1 - x or x = 2 - x
x + x = 1 or x + x = 2
2x = 1 or 2x = 2
x = 1/2 or x = 2/2
x = 1/2 or x = 1
So, the solution is x = 1/2 or x = 1

To purchase $12,200 worth of restaurant equipment for her business, Linda made a down payment of $1600 and took out a business loan for the rest. After 3 years of paying monthly payments of $322.48, she finally paid off the loan.
(a) What was the total amount Linda ended up paying for the equipment

How much on loan:
12,200 - 1,600 = $10,600 loan amount
How much paid on loan:
$322.48 * 3 years * 12 months = $11,608.28 amount paid on loan
Total paid:
