Answer:

he could drive 4 hours

Step-by-step explanation:

Step-by-step explanation:

if he drives for 1 hour he will have 21 gallons left

2 hours = 15 gallons left

3 hours = 9 gallons left

4 hours = 3 gallons left

4.5 hours = 0 gallons left

he could drive a total of 4.5 hours before he runs out of gas

Answer:

The number of times he visited the gym is 19 times.

Step-by-step explanation:

A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195, how many times did he visit the gym? Define Variable: Equation: Solve (Show all steps):

Let the number of times he visits the gym be represented as x

A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195,

The Amount he spends = $195

= $100 + $5 × x

$195 = $100 + 5x

5x = $195 - $100

5x = $95

x = 95/5

x = 19 times

Therefore, the number of times he visited the gym is 19 times.

7/8 is the fraction

7 is the numerator

8 Is the denominator

Answer:

There isn't a graph or more information to use to find the ratio but I'll put here 3 ways to write a ratio so hopefully that might help. If more information is added later I will edit the answer.

Step-by-step explanation:

First way:

Use the word "to". For example: 2 to 4.

Second way:

Use a fraction. For example: 2/4.

Third way:

Use a colon. For example: 2:3.

Answer: A=x^2+7x+12

Step-by-step explanation:

A=area of triangle. h=height. b=base

A=bh/2

A=(x+4)(2x+6)/2

A=(x+4)(2x/2+6/2)

A=(x+4)(x+3)

A=x*x+4x+3x+4*3

A=x^2+7x+12

.......................

Answer:

3

Step-by-step explanation:

The formula of to calculate slope of a linear function is

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

where m is the slope and so lets take any two points from the table to calculate the slope. Lets take,

(0 , 4) and (1 , 7) and lets plug it in the formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{7-4}{1-0}\\\\m=3[/tex]

So the slope of the function is 3

Answer:

We conclude that when we put x = 11, it does not satisfy the inequality.

Hence, option (A) is correct.

Step-by-step explanation:

Given the inequality

x - 7 > 12

Any value which makes the inequality FALSE would be the value that not satisfy the inequality.

Putting x = 11 in the inequality

x - 7 > 12

11 - 7 > 12

4 > 12

FALSE!

Reason: 4 can not be greater than 12

Putting x = 33 in the inequality

x - 7 > 12

33 - 7  > 12

26 > 12

TRUE!

Reason: 26 is indeed greater than 12

Putting x = 22 in the inequality

x - 7 > 12

22 - 7 > 12

15 > 12

TRUE!

Reason: 15 is indeed greater than 12

Putting x = 44 in the inequality

x - 7 > 12

44 - 7 > 12

37 > 12

TRUE!

Reason: 37 is indeed greater than 12

Therefore, we conclude that when we put x = 11, it does not satisfy the inequality.

Hence, option (A) is correct.

Answer:

11

Step-by-step explanation:

Answer:

70

Step-by-step explanation:

|-11| becomes positive cuz its an absolute. so its just 50 +11

Answer:

70

Step-by-step explanation:

The absolute value (the two lines that the -11 are between) refers to a numbers distance from zero. So more or less just remove the negative sign and add like normal.

[tex]-4,9t^2+33,6t+4,9=0\\\Delta=33,6^2+4*4,9*4,9=1225\\\sqrt{\Delta }=35\\t=\frac{-33,6-35}{2*(-4,9)} =14s[/tex]

Step-by-step explanation:

The toy rocket will take a time of 6.8571 seconds to hit the ground.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given that the height of the rocket (h), in meters, in terms of time (t), in seconds, is defined by a quadratic equation.

To determine the time needed for the rocket to hit the ground, that is, a time t greater than zero such that the height is zero. Now we proceed to solve the polynomial:

- 4.9 · t² + 33.6 · t + 4.9= 0

- 4.9 · (t² - 6.8571 · t - 1) = 0

- 4.9 · (t - 6.8571 ) · (t + 6.8571 ) = 0

Hence, the toy rocket will take a time of 6.8571 seconds to hit the ground.

Answer:

B: 20 sq. inches

Step-by-step explanation:

The area of the triangle is calculate by;  A= b. h /2

b= 10 inches

h = 4 inches

10 . 4= 40 sq. inches : 2 = 20 sq.inches

The area of the triangle is 20 sq. inches

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.This means that if the object x is in the set of inputs (called the domain) then a function f will map the object x to exactly one object f(x) in the set of possible outputs (called the codomain).

We can write the statement that f is a function from X to Y using the function notation f:X→Y.

Answer:

92

Step-by-step explanation:

Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.

Answer:

8 + 2w

Step-by-step explanation:

⇒ Change all signs to addition (subtraction is the same as adding a negative):

5 + 3w + 3 + -w

⇒ Since the expression is now all addition, you can rearrange them in any order. So group the terms together by their type:

5 + 3 + 3w + -w

⇒ Simplify:

8 + 2w

Answer: 8 + 2w
