What is the value of z so that’s -9 and 9 are both solutions of x^2+z=103

Answers

Answer 1

Answer:

we have been given that x=-9 and x=9 then putting two values of x in the given equation we can find the value of z. I've got the value of z as 22

Step-by-step explanation:

The given equation is :

x^2+z=103

If we put x as (-9) ,

(-9)^2+z = 103

or, 81 +z = 103

or, z= 103-81

or,z=22 (Answer)

Now , again if we put x as 9,

9^2+z=103

or, 81+z=103

or,z=103-81

or,z=22 (Answer)

THEREFORE THE VALUE OF Z IS 22

Mishka is on a long road trip, and she averages 75 mph for 2 hours while she's driving on the highway. While she's driving on side roads for 1 hour, she only averages 45 mph. What is the total distance that she covers on her road trip?
A.
120 miles
B.
195 miles
C.
240 miles
D.
75 miles

Answers

If she goes 75 mph for 2 hours, that's 150 miles altogether. 45 mph for 1 hour is 45 miles, so 150 + 45 is 195 miles.

The total distance that Mishka covers on her road trip is 195 miles.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

To calculate the total distance covered on the road trip

we need to add the distances traveled on the highway and side roads.

Distance on the highway = speed × time

= 75 mph × 2 hours

= 150 miles

Distance on side roads = speed × time

= 45 mph × 1 hour

= 45 miles

Total distance covered = Distance on the highway + Distance on side roads = 150 miles + 45 miles

= 195 miles

Therefore, the total distance that Mishka covers on her road trip is 195 miles.

Ryan is using tiles in his bathroom. He chooses 1" x 2" tiles for the border and would like tiles that are similar to the border as the interior tiles. Interior tiles will be larger by scale factor of 3.5. What are the dimensions of the interior tiles?

Answers

Answer:

The area of the interior tiles must be 7 inches ² with dimensions 1.871" x 3.742".

Step-by-step explanation:

Since the interior tiles must be 3.5 larger then the border tiles to calculate the dimensions of the interior tiles we first need to find the area of the border tiles. This is shown bellow:

area border = 1*2 = 2 inches²

The area of the interior tiles is 3.5 larger than that, so we have:

area interior = 2*(area border) = 2*3.5 = 7 inches²

In order to maintain the same proportions as the border tiles we must find a width that is two times the height, so we have:

area interior = width*height = 2*height*height = 2*height²

7 = 2*height²

height² = 3.5

height = sqrt(3.5) = 1.871

width = 2*height = 2*1.871 = 3.74166

The area of the interior tiles must be 7 inches ² with dimensions 1.871" x 3.742".

The interior tiles that Ryan wants to use in his bathroom will have dimensions of 3.5 inches by 7 inches.

Ryan is using 1" x 2" tiles for the border of his bathroom and wants to use similar tiles for the interior that are larger by a scale factor of 3.5.

To calculate the dimensions of the interior tiles, you simply multiply the dimensions of the border tiles by the scale factor. Therefore, the dimensions of each interior tile will be:

2 inches (width of border tile) x 3.5 = 7 inches (width of interior tile)

Ferris wheel has a diameter of 60 ft. How far will a rider travel during a 5 minute ride if the wheel rotates once every 15 seconds?

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Now , the value of A is

a)

y = 0.5x - 2   be equation (1)

y = -0.5x + 4   be equation (2)

On simplifying both the equations , we get

0.5x - 2 = -0.5x + 4

Adding 0.5x on both sides of the equation , we get

x - 2 = 4

Adding 2 on both sides of the equation , we get

x = 6

Substitute the value of x in equation (1) , we get

y = 1

The value of x is 6 and value of y is 1

b)

y = 0.5x + 5   be equation (1)

y = 0.5x + 1   be equation (2)

On simplifying both the equations , we get

0.5x + 5 = 0.5x + 1

Now , the equations are contradictory and there are no solution

c)

y = 2x + 1   be equation (1)

y = 4x + 1   be equation (2)

On simplifying both the equations , we get

2x + 1 = 4x + 1

Subtracting 2x on both sides of the equation , we get

2x + 1 = 1

Subtracting 1 on both sides of the equation , we get

2x = 0

x = 0

Substitute the value of x in equation (1) , we get

y = 1

Therefore , the value of x is 0 and value of y is 1

d)

y = 3x + 2.5   be equation (1)

y = 3x + 2.5   be equation (2)

On simplifying both the equations , we get

3x + 2.5 = 3x + 2.5

Therefore , the equations are similar and there are infinite number of solutions

e)

y = -x - 3   be equation (1)

y = -x + 3  be equation (2)

On simplifying both the equations , we get

-x - 3 = -x + 3

Now , the equations are contradictory and there are no solution

Dr. Don offers a tutoring service for college students. He charges $40 as a fixed rate for the first hour plus $20 for each additional hour. What is the minimum and maximum number of hours of tutoring a student can get if he or she can afford to spend between $140 and $200? (Express your answer as an inequality)

Answers

Answer: 6  ≤ h ≤ 9

Step-by-step explanation:

Hi, since He charges $40 as a fixed rate for the first hour plus $20 for each additional hour, the cost of the tutoring service is equal to the fixed rate(40) plus, the product of the additional hours (h-1) and the cost per additional hour (20).

40+20(h-1)

40+20h-20

20+20h

Since a student can spend between $140 and $200, the previous expression must be greater o equal than 140, and less or equal than 200.

140≤20+20h≤200

Subtracting 20

140-20 ≤20-20+20h ≤200-20

120 ≤ 20h ≤ 180

Dividing by 20

120/20 ≤ 20h/20 ≤ 180/20

6 ≤ h ≤ 9

Final answer:

The minimum and maximum number of hours of tutoring a student can get if they can spend between $140 and $200 is 5 and 8 hours, respectively.

To determine the minimum and maximum number of hours of tutoring a student can get, we need to set up an inequality based on the pricing information provided. Let's denote the number of additional hours beyond the first hour as x.

The total cost of tutoring will be $40 for the first hour plus $20x for each additional hour. The student can afford to spend between $140 and $200, so the inequality is:
140 ≤ 40 + 20x ≤ 200

To find the solution, we need to isolate x. First, subtract 40 from all parts of the inequality:
100 ≤ 20x ≤ 160

Next, divide all parts of the inequality by 20:
5 ≤ x ≤ 8

Therefore, the minimum number of hours is 5 (including the first hour) and the maximum number of hours is 8 (including the first hour).

Answers

Final answer:

A 90° counterclockwise rotation is the same as a 270° clockwise rotation. A 180° rotation is the same as a reflection across both axes. A 90° clockwise rotation is the same as a 270° counter-clockwise rotation. Two separate rotations of 90° counter-clockwise and then 180° are the same as rotations of 90° clockwise and then 180°.

Explanation:

In mathematics, especially in geometry, transformations involve changing the position, size or shape of a figure. The question is about matching specific transformations or sequence of transformations to its equivalent transformation.

A 90° counterclockwise rotation about the origin is equivalent to a 270° clockwise rotation about the origin because they both result in the same final position.A 180° rotation about the origin is equivalent to a reflection across the x-axis and then a reflection across the y-axis. Both of these transformations result in the figure being flipped over the origin.A 90° clockwise rotation about the origin  is equivalent to a 270° counterclockwise rotation about the origin as they both result in the same final position.A 90° counterclockwise rotation about the origin and then a 180° rotation about the origin is equivalent to a 90° clockwise rotation about the origin and then a rotation 180° about the origin because they both result in the same final position.

He tightened the jacket around his neck and silently thought Why did I not listen to Mom? with anger. Earlier that day, his mom had told him to carry his scarf, gloves, and cap, but he had refused by saying that they made his bag heavy and that he would not need them. It was a pleasant day after all! However, by the time school ended, the ground was covered with snow. "You should have carried your gloves and cap," Jack's friend, Daisy said, as she trudged along beside him. "I know!" Jack snapped, telling himself never to make such a mistake again. They had almost reached Jack's house when Daisy suddenly stopped and began looking around in confusion. "What is it, Daisy?" Jack asked as he shook uncontrollably. "I thought I heard a noise," Daisy said, continuing to look around. A nearby dumpster suddenly shook, and the two jumped in surprise. "What is that?" Jack asked and walked behind the dumpster. To his surprise, he found a dog crouching beneath the dumpster and whimpering in fright. "Poor thing must be freezing in this cold," Daisy said and gently patted the dog's head. "We cannot leave him here. Jack, your house is close by so you can take him home." Before Jack could respond, Daisy lifted the dog and put him in Jack's arms.The dog was much lighter than Jack had expected, and Jack looked down at the dog's frightened face. He sighed and wrapped his arms tightly around the dog and jogged home. When Jack's mom opened the door, her mouth fell open when she saw a trembling Jack carrying a stray dog, but she did not say a word and quietly stepped aside to let them in. Once inside, Jack ran to the fireplace to warm himself and asked his mom for a glass of hot milk. When she brought the milk, he began gulping it down hungrily. But when he noticed the dog looking at him, he stopped and looked at his half-filled glass. "Here you go, boy," Jack said pouring the rest of the hot milk in a saucer and giving it to the dog. With a grateful look, the dog emptied the saucer, and Jack felt thrilled to see that sharing his glass of milk gave the frightened, little dog such happiness. He ran to the kitchen to fetch some more milk for the dog and himself.1Select ALL the correct answers.Which two events cause Jack to change over the course of the story? A) Jack listens to Daisy's advice about carrying warm clothes. B)The fireplace and hot milk make Jack feel warm and comfortable. C) Jack brings the frightened stray dog home and feeds him hot milk.
