Answer:

No, it is not a right triangle.

Step-by-step explanation:

The simplest way to determine is testing out the numbers with Pythagorian theorem.

If it complies with the theorem, it is a right triangle.

let's assume c = 28, b = 21, and a = 20

the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.

According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.

check:

c^2 = 28^2 = 784

a^2 + b^2 = 21^2 + 20^2 = 841

because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.

Answer:

In the equation y = mx + c the value of m is called the slope, (or gradient), of the line. It can be positive, negative or zero. The value of c is called the vertical intercept of the line. It is the value of y when x = 0. When drawing a line, c gives the position where the line cuts the vertical axis.

Answer:

b: 5/7

Step-by-step explanation:

Answer:

5/9

Step-by-step explanation:

You got to find 2 points that you want and use the formula y1-y2 and x1=x2 and you find your slope.

Answer:

-5

Step-by-step explanation:

y=mx+b is the slope intercept formula.

m is the slope.

Answer:

slope = - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 5x - 1 ← is in slope- intercept form

with slope m = - 5

Answer:

2 days

Step-by-step explanation:

Assume that Annie and Abby watched the same number of episodes in [tex]t[/tex] days.

Number of episodes watched by Annie [tex]=4+1(t)=4+t[/tex]

Number of episodes watched by Abby [tex]=3t[/tex]

[tex]4+t=3t\\4=3t-t\\4=2t\\t=2[/tex]

So,

Annie and Abby watched the same number of episodes in [tex]2[/tex] days

Answer:

D

Step-by-step explanation:

Rolling a die and getting a certain number will not change the chances of you getting the same number a second time. A normal die will always have a 1/2 chance of rolling an even number. However, the other answer choices will make the likelihood of getting the same type of event again slimmer as you remove one of the objects from being chosen again. An example for the first option would be drawing an ace from a deck of 52 cards where you only have 4 aces, so the chance on the first draw would have been 4/52 or a 7.7% chance while the next draw will be a 3/51 or 5.9% chance.

Answer:

1. x= -6

2. x= -4

3. x= -7

4. x= 33

Answer:

$5.625

Step-by-step explanation:

Cost per pound of beef = $1.25 per pound

Number of pounds purchased = 3.5 pounds

Amount given to cashier = $10.00

Amount of change to receive from cashier =?

Amount issued to cashier - total cost of beef

Total cost of beef = (number of pounds * cost per pound)

Total cost of beef = (3.5 * 1.25) = $4.375

$10 - $4.375 = $5.625

Answer:

51% of 200 =

102

Step-by-step explanation:

51           x     200  =  10200

100                  1  =      100       10200/100 = 102

percentages is out of 100

Another way:

51/100 is .51 so just multiply it by 200!

.51 x 200 = 102

Hope this helps you out! :)

Answer:

Step-by-step explanation:

How you get 51% of 200 is by multiplying 51 by 200 then dividing the value of 51 times 200 by 100.

51 ⋅ 200 = 10200 ÷ 100 = 102 Steps

So, 51% of 200 equals 102 Steps

Your answer, many solutions is correct!

Step-by-step explanation:

The answer one solution is incorrect because there is more than one solution to this equation.

The answer no solution is incorrect because there is a solution to this equation so clearly, this one is incorrect.

The answer many solutions is correct because there are two solutions to this equation, [tex]y=-3,\:x=\frac{9}{2}[/tex].

(Try using Symbolab, I use it all the time it gives the correct answer and it gives good explanations.)

Answer:

yeah correct

Step-by-step explanation:

This is not a very good thing to be doing, but I use Slader. On Slader, people answer the questions on textbooks. I guess it's kind of like Brainly, but the questions are already there. I used to use Slader for Big Ideas. Make sure to read the explanations so you get the topic though.

Step-by-step explanation:

Answer:

Look at explanation

Step-by-step explanation:

y = mx + b

m is the slope, and b is the y-intercept

So basically on the y-axis, which is the vertical line, u will make a point on 4, and that point is where your line will go through. And then 3 is the slope ur line will be going in, meaning that the line will go up 3 square units, or number, while only going one square unit to the right. It's going up and right because it's a positive number. So it should look like this:

Answer:

- 7x - 10y

Step-by-step explanation:

You add the “like” terms.

x - y - 8x - 9y

x - 8x  And - y - 9y

-7x - 10y

Answer:

-7x-10y

Step-by-step explanation:

1. Combine like terms

= x+−y+−8x+−9y

= (x+−8x)+(−y+−9y)

= −7x+−10y

We need to see the "given system".

Answer:

Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

Answer:

He has 0 yards

Step-by-step explanation:

Initially he lost 10 yards

This means that he is 10 yards away from the starting point which we shall call origin

Afterwards, he gained 10 yards

what this mean is that he is back at the original point before the loss

Since he gained what he lost, then he is back at the origin and then we can say that no yards was lost or gain so we have him gaining 0 yards only

Answer:

The answer is A. 1385 cm2

Step-by-step explanation:

Use the formula A = pi times radius squared

Answer:

A. 1385 cm²

Step-by-step explanation:

Area of a circle is πr²

We know what the radius is, so all we have to do is plug it in.

π(21)²

π(21)²= 1385.44

Since it's approximate, it would just be 1385 cm²
