Answer:

  40 in

Step-by-step explanation:

The Pythagorean theorem tells you the relationship between the sides of a right triangle.

  b^2 +75^2 = 85^2

  b^2 = 85^2 -75^2 = 1600

  b = √1600 = 40

The length of the missing side is 40 inches.

Answer:

13.5 and 7

Step-by-step explanation:

x + y = 20.5

× - y = 6.5

Hence,

x =20.5 - y

20.5 - 2y = 6.5

Hence,

2y = 14

and x = 20.5 - 20.5 - 7 = 13.5

Hope that helps :))

Answer:

The two numbers are 7 and 13.5

Step-by-step explanation:

Let the two numbers be x and y

Make 3 equations (for system of equation and substitution method)

Equation 1. x - y = 6.5

Equation 2. x = 6.5 + y

Equation 3. x + y = 20.5

Use the value of x in equation 2 to substitute x in equation 3.

6.5 + y + y = 20.5

Combine like terms

6.5 + 2y = 20.5

- 6.5 on both sides

2y = 14

Divide both sides by 2 to isolate y

y = 7

Substitute y in equation 3 to find x

x + 7 = 20.5

x = 13.5

Hope this helps :)

Have a great day!

Answer:

im guessing it is 78/100 because u circled 78

Step-by-step explanation:

because 21 + 1 + 78 = 100

so 78/100 is the fraction

Answer:

78/100 or 39/50 (simplified)

Step-by-step explanation:

First, let's convert 78% into a decimal.

Now, we know that 0.78 is the same thing as 78/100. We can simplify 78/100 into 39/50, where 2 is the GCF

Thus, the answer is 78/100 or 39/50.

Can't see answer it's blank

Step-by-step explanation:

Answer:

First option) y= 2x - 3

Step-by-step explanation:

[] The y-intercept, our b, is -3. This does not rule out any of the options as they all have -3.

[] The slope, when we have a graph with clear points, can be found with rise-over-run. We will pick a point and then count up and over to the next point.

-> Starting at the y-intercept, (0, 3), we count up 2 and to the right 1 for a slope of 2/1. This simplifies to 2.

[] Our equation is y = 2x - 3

Have a nice day!

Answer:

16 students

Step-by-step explanation:

Knowing that 4 is 20% of a certain number is a great start. Think, how many times does 20 go into 100, 4. So then you multiply 4 with 4.

4 · 4 = 16

Step-by-step explanation:

25 + 9³ = 25 + 81 = 106

remember, the cube of a number means to multiply it with itself 3 times (for a squared number that would be 2 times).

9³ = 9×9×9

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division

The value of the expression 25 + 9³ is 754.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The sum of 25 and the cube of 9.

This can be written as,

25 + 9³

= 25 + 729

= 754

Thus,

The value of the expression 25 + 9³ is 754.

Answer:

1) X + 234 = 633

2) t = 63

3) x = 12

Step-by-step explanation:

1 is simple subtraction, just subtract the whole by the number that is given. Then that will fill X.

2 is multiplication. If a variable is (for example, x) next to a number that means it is multiplying it by a hidden number. To find that, you multiply the number next to the variable. If the sum matches the solution, there you go.

Answer:

(5r-2)/3 = s

Step-by-step explanation:

-6= -15r+9s

Add 15r to each side

-6+15r= -15r+15r+9s

15r-6 = 9s

Divide each side by 9

(15r-6)/9 = 9s/9

(5r-2)/3 = s

Answer: Evaluate

Step-by-step explanation:

Answer:

D.  1/12^-4

Step-by-step explanation:

[tex]12^{-5}*12^{9}[/tex]

Since both exponents have the same base, we can add the exponents to get:

[tex]12^{-5+9}=12^{4}[/tex]

We can cross out A and B since they multiplied the two exponents, therefore both answers are wrong.

Now, let's try C and D.

C is wrong because it has a different base being raised to the same power.

D is correct. When you have a negative exponent, it is equivalent to the reciprocal of the base to the positive exponent.

The reciprocal of 1/12 is 12, and the positive of -4 is 4, therefore the answer is D.

Answer:

~0.143

Step-by-step explanation:

So, in total there are 15 marbles, and only 6 of them are red. So the first draw will have a  chance of being red. Since you didn't mention placing it back, the next draw will have a  chance of being red. It's  , because you just took a red one out of the bag (leaving 5 left) and the total was lessened by one. To get the answer, you'd multiply both numbers together.

6/15 x 5/14 = 1/7 or (roughly) 0.143

Answer:

Total area = 26.13 ft²

Step-by-step explanation:

area of a triangle = 1/2 x base x height

From inspection, the base of the triangle = 3 x 2 = 6

and the height of the triangle = 4

⇒ area = 1/2 x 6 x 4 = 12 ft²

area of a semicircle = [tex]\frac{1}{2}\pi r^2[/tex]

⇒ area = [tex]\frac{1}{2} \times 3.14 \times 3^2[/tex]

⇒ area = 14.13 ft²

Total area = 12 + 14.13 = 26.13 ft²

Answer:

5x^2-8x + 12

Step-by-step explanation:

the formula for finding roots of equation is

x^2- (sum of roots)x + products of roots =0

and we already have the roots of the equation

so we add them to give 8

and multiply to give 12

hence the quadratic equation that has those roots with leading coefficient is 5x^2-8x + 12=0

Answer:

It is parallel and yes you can prove it.

Step-by-step explanation:

I would use a tool that you can use to figure out the angle, check all the corners and if the smaller one are the same and the wider corners are the same then then would be parallel. That only works though if there was a line going through like your problems. If you had a graph it would be easier.
