Answer:

only 75% of the class or students passed the algebra test

Answer: 75%

Step-by-step explanation: The equation for percentages is: part = percent • whole.

We can use our given values and plug them into the equation to solve for our percent.

In this problem, the “part” is 18, and our “whole” is 24, since the whole class has 24 people, and part of the class (18) passed.

P = % • W

18 = % • 24

(to solve for %, we have to get isolate it, or get rid of the • 24. We use division, the opposite operation, to cancel our • 24.)

18 = % • 24

÷24 ÷24

0.75 = %
Since percents are out of 100, we have to multiply 0.75 by 100.

0.75 • 100 = 75%

(2, 1) and (4, 2): [tex]\frac{1}{2}[/tex]

(-4, 5) and (-3, -7): [tex]-12[/tex]

Step-by-step explanation:

Hello! Let's help you with that problem there!

So we know that in a slope intercept form, it is depicted as [tex]y=mx+b[/tex]. There are two ways to essentially find m, which is slope in this case. The first method is the [tex]\frac{rise}{run}[/tex] method. This is typically used when you have a graph to look off from and it's just a matter of counting the displacement from one point to another.

However, there is another way to find the slope given 2 points and that is what we are going to do here, since we have no graph to reference and have all the relevant information to find the slope using this formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

With this formula, we can plug in the coordinate values and solve for the slope!

(2, 1) and (4, 2):

[tex]m=\frac{2-1}{4-2}[/tex]

[tex]m=\frac{1}{2}[/tex]

Therefore, the slope of these points is [tex]m=\frac{1}{2}[/tex]

(-4, 5) and (-3, -7):

[tex]m=\frac{-7-5}{-3-(-4)}[/tex]

[tex]m=\frac{-12}{1}[/tex]

[tex]m=-12[/tex]

Therefore, the slope of these points is [tex]m=\frac{-12}{1}[/tex] or [tex]m=-12[/tex]

The farmer has 28 cows from a total of 80 animals in the farm.

Each chicken has two legs and each cow has four legs. The farmer has a total of 216 legs among all the animals, which are 80. Then, we can represent the situation with the following system of linear equations:

x + y = 80

4 · x + 2 · y = 216

Where:

The system can be solved easily by some algebraic handling:

x = 80 - y

4 · (80 - y) + 2 · y = 216

320 - 4 · y + 2 · y = 216

320 - 2 · y = 216

2 · y = 320 - 216

2 · y = 104

y = 52

x = 80 - 52

x = 28

The farmer has 28 cows.

The sales price of washing machine is 250.

The price at which something sells or is offered for sale after having its price lowered is known as sales price. 

A sale price is the reduced cost at which goods or services are offered for sale. Typically, this price is provided for a brief period of time in an effort to boost sales during a slow period or get rid of extra inventory.

The promotional price is indicated as a percentage off of the standard list price.

Let x be the sales price of washing machine, then as per given

17% of x = 42.5

The z-score corresponding to a score that is 12 points above the mean is 2.

The z-score is a numerical measurement used in statistics to determine the sample data value's relationship to the mean of a group of values, measured in terms of standard deviation from the mean. It is measured as the difference of the sample data value and the sample mean over the standard deviation, such that

z-score = (x – μ) / σ

where x = sample data value

μ = mean

σ = standard deviation

If the sample score is 12 points above the mean, then (x – μ) = 12.

(x – μ) = 12

σ = 6

Substitute the values to the z-score formula.

z-score = (x – μ) / σ

z-score = 12/6

hello

the question presented here related to compound interest and we can solve that using the formula

let's proceed to substitute the values into the equation

the compounded interest compounded monthly at 6% for 5 years is 3375

The amount is  3250

The accumulated amount is calculated using the initial investment and  interest earned in the given duration

The formula for simple interest is  P×R×T and further, it is divided  by 100

SI= 2500 ×  6 × 5 =75000 ÷100 = 750

Now, for calculating the accumulated amount we will add the initial investment and the interest gained

ie, 2500+750 =3250

Here we are using the simple interest method to calculate the interest as it is assumed to be taken as simple interest when nothing is specified.

The equation of the line with slope -3/4 and y intercept 9 is y=-3/4x+9.

Based on the conditions formulate:

m=-3/4

and b = 9

Write the equation of the linear function:

y=mx+b

substitute m=-3/4 and b=9 into y=mx+b:

y = -3/4x+9

A line's equation must be in the Slope-Intercept Form, y = mx + b, in order to be graphed using its slope and y-intercept.

This format makes it simple to read off the slope and y-intercept values. The y-intercept is the constant term b, whereas the slope is just the m coefficient of the variable x.

a) To know the total millilites that sam use to fil the dispenser, we will have to add all the seven amount filled as shown;

Total (in milliliters) = 350 mL + 600 mL + 475 mL + 580mL + 720mL + 500 mL

Total (in milliliters) = 3225mL

Hence the total milliliters that sam use to fill the dispensers is 3225millilitres

b) The amount liters of sanitizer remaining will be 12litres - 3225mL

Convert 3225mL to litres

3225mL = 3225/1000 Litres

3225mL = 3.225litres

The amount liters of sanitizer remaining = 12 - 3.225

The amount liters of sanitizer remaining = 8.775litres

Answer:

∠ 2 = 140°

Step-by-step explanation:

the left base angle in the triangle and 110° are a linear pair and sum to 180°

base angle + 110° = 180° ( subtract 110° from both sides )

base angle = 70°

the 2 sides of the triangle are congruent so Δ is isosceles with base angles congruent.

the vertex of the Δ is then

(180 - 70 - 70)° = 180° - 140° = 40°

the vertex and ∠ 2 are a linear pair and sum to 180° , that is

∠ 2 + 40° = 180° ( subtract 40° from both sides )

∠ 2 = 140°

Step-by-step explanation:

step one you will need to find the slope by the Y2 minus y1 all over x2 minus X1 formula. so you would have -2 - 4 all over 5 - 3 . you will get -6 over 2 which is equal to -3 . that means that -3 is the slope .

Step 2 you can find the equation with the point slope form formula . the point slope form formula is y-y1=m(x-x1). by substituting your values into these equation you can find the equation of this line . you can substitute any point into it as long as it is on the line . let's use (3,4) where 3=x1 and 4=y1.

step 3. simplify. you will get y-4=-3(x-3). keep in mind I substituted -3 into the equation because -3 is the slope.
