Answers

Answer:

C. 30

Step-by-step explanation:

Distance formula - [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]

The scale factor of 7 is basically saying that the coordinates (3,4) are going to be increased 7 times.

3•7 = 21=x         --> A prime = (21,28)

4•7 = 28=y

[tex]\sqrt{(21-3)^2+(28-4)^2}[/tex]

= [tex]\sqrt{324+676}[/tex]

The number of hot dogs Ryan can eat varies directly with the amount of time he spends eating. If Ryan can eat 14 hot dogs in 6 minutes, how many hot dogs can he eat in 15 minutes?

Answers

Answer:

35

Step-by-step explanation:

If I am not correct I'm sorry.

If Ryan can eat 14 hot dogs in 6 min then he should be able to eat about 35 hot dogs in 15 mins.

14/6= 2.333...

so 2.333... x 15 would equal 35

I hope this helps.

Answer:

Ryan can eat about 34.5  hot dogs in 15 minutes

Step-by-step explanation:

You first need to find how many hot dogs ryan eats in one minute. By doing this you need to do 14 divided by 6 and that will get you to 2.3

Than you need to take that 2.3 and muliply it by the 15 minutes and than that would get you to your answer of 34.5 hotdogs in 15 minutes

Answers

Answer:

88 cars132 trucks

Step-by-step explanation:

This is a ratio problem, the ratio of  cars to trucks

for every 4 cars, there are 6 trucks

represented as a ratio we have 4:6

1. how many of them are cars

applying the part to whole strategy we have

4+6 = 10

let cars be x

[tex]\frac{4}{10}= \frac{x}{220} \\\\x= \frac{220*4}{10} \\\\x= 880/10\\\\x= 88 cars[/tex]

2.  how many of them are trucks?

let trucks be y

[tex]\frac{6}{10}= \frac{y}{220} \\\\x= \frac{220*6}{10} \\\\y= 1320/10 \\\\y= 132 trucks[/tex]

Steve Fossett completed the first solo balloon circumnavigation of the world after 13.5 days. Assuming the balloon travelled along a circle of diameter 12 750 km, roughly what was the average speed of the balloon in km/h?

A) 12
B) 40
C) 75
D) 120
E) 300​

Answers

Answer:

B) 40

Step-by-step explanation:

Average speed = distance/time

Distance = 12750 km

Time = 13.5 days = 13.5*24  hours = 324 hours

Speed = 12750 km /324 h =  39.4 km/h ≈ 40 km/h

Correct option is B) 40

which situation could NOT represent a proportional relationship? F The number of gallons of water in x barrels with 42 gallons of water in each barrel G The amount an employee who makes $8.50 per hour earns in h hours the weight in x weeks of a puppy that gains 2 pounds per week it is starting weight is 8 pounds 1 The cost of purchasing p pounds of bananas for $0.55 per pound​

Answers

Answer: it’s H <3

Step-by-step explanation: I had this on my homework and I got it right^^

It is possible that the situation does not represent a proportional relationship. The number of hours worked by an employee earning $8.50 per hour.

What proportional relationship?The relationship is said to be proportional when two or more items are directly proportionate or change in size according to equivalent ratios.The formula y = kx can be used to express this proportional relationship. The quantities that are proportional to one another in this case are y and x.In this case, the unit rate is another name for the proportionality constant (k).Proportional relationships can be worked with algebraically, but they can also be represented visually by graphing them on a coordinate plane.On the graph, a proportionate relationship is always represented as a straight line across the origin.

Therefore, The correct answer is option is B) The amount an employee who makes $8.50 per hour in h hours

The complete question is:

Which situation could NOT represent a proportional relationship?

A: The number of gallons of water in x barrel with 42 gallons of water in each barrel

B: The amount an employee who makes $8.50 per hour in h hours

C: The weight in x weeks of a puppy that gains 2 pounds per week if it's starting weight is 8 pounds

D: The cost of purchasing p pounds of bananas for $0.55 per pound​

What value of x makes this equation true?
3(x + 4) = 7x - 18
O x = 5
O x = 4.5
O x = 34.5
0 x = 75.

Answers

Answer:

x = 15/2 or x = 7.5

Step-by-step explanation:

Step 1: Write equation

3(x + 4) = 7x - 18

Step 2: Solve for x

Distribute 3: 3x + 12 = 7x - 18

Subtract 3x on both sides: 12 = 4x - 18

Add 18 on both sides: 30 = 4x

Divide both sides by 4: x = 15/2 or x = 7.5

Can someone solve these please using the formula AB | a - b |

And can you show work

Answers

Answer: 1) AC = 13

The formua does not actually apply to all of the problems.

Step-by-step explanation:

1) The absolute value of -8 is added to the absolute value of 5. 8+5=13

2) Subtract the length of the EF from EG to get the length of FG 21 -6 = 15

3) Take what's given and create an equation to solve. 4x + 15 +39 =110. 4x = 110 - (15+39).

4x =110-54. 4x =56. x=56/4. x=14

4) Create another equation. You have two segments that add up to the length of EG, given =23

EF+FG=EG

(2x-12)+(3x-15)=23

5x - 27 = 23

5x= 23+27 5x =50. x = 10

Substitute 10 for x

EF=2(10) -12 EF=8

FG=3(10)-15. FG=15

EF+FG =EG.

8 + 15 = 23

5) 2/5 of 25 is 10 So EF is 10. Subtract from 25 to get FG

FG = 15

grade 7. i actually already learnt this but this whole quarantine thing made me forget lolz. what are factors?
example : is 3 a factor of 372?
please answer and explain <3​

Answers

Answer:

A number in a multiplication equation that makes up the total. For example,

2 x 3= 6.

2 and 3 are the factors.

Answer:

A factor is basically a number that derives from another without leaving a remainder. It sounds somewhat confusing when put into words but I'll give you some examples.

Step-by-step explanation:

in the problem you stated the answer would be yes. 3 is a factor of 372 because you can multiply 3 times another number (which in this case is 124) to get 372.

In addition, a number can have several factors. For example, these are all the factors for the number 10: 1, 2, 5, 10

notice how all these numbers multiplied by another of these same numbers on the list give you 10.
