George and carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 350 miles in total, and they biked 80 kilometers more than they were bused.

Answers

Complete question − How many kilometres did they travel by bus and by bicycle.

Answer:George and carmen traveled by bus in 135km and by bikein 215km

Step-by-step explanation:

Total Miles traveled  =   350 miles  

Let Number of kilometres they traveled with bus  = x

and Let Number of kilometres they traveled with bike = x + 80

so that the total distance traveled with bus and bike be expressed as

x + x + 80 =   350 miles  

2x + 80 =   350 miles  

2x =   350 − 80

2x =270

x=135

George and Carmen traveled by bus in 135km  

and by bicycle=x + 80 = 135 km + 80 =215km

Which of the following angle measurements would you find in an equilateral triangle?
A. 45°, 45°, 45°
B. 45°, 45°, 90°
C. 50°, 50°, 50°
D. 60°, 60°, 60°

Answers

Answer:

D. 60, 60, 60

Step-by-step explanation:

In an equilateral triangle, all sides are equal and equal to 180 when added together. because 60×3 is equal to 180, D is the right answer. I hope this helps you!

The angle measurements found in an equilateral triangle are 60°, 60°, 60°

What is an Equilateral Triangle?

An equilateral triangle is an angle that has equal angles and equal sides. It implies that all the sides of the angle contain the same length.

We can also say that an equilateral triangle is also equiangular since it has equal angles. If we recall, we know that the sum of angles in a triangle is 180°.

For a triangle with equal sides, it implies that each length will possess;

= 180°/3

= 60° each.

Is the relation {(1, 3), (–4, 0), (3, 1), (0, 4), (2, 3)} a function? Why or why not? No, the range value 3 corresponds to two domain values, 1 and 2. ... No, there is no value in the domain that corresponds to more than one value of the range.  Jun 13, 2017

Step-by-step explanation:  The answer is either letter B or letter D.

Determine if the relation is a function.

The relation is a function.

Answer:

D

Step-by-step explanation:

We say a relation between two sets is a function if every value in the first set (the domain) corresponds to exactly one value in the second (the range). This doesn't mean we can't have two different domain values pointing to the same range value, but it does mean we can't have on domain value pointing to two different range values.

Our relation here is a function, since each domain value only points to one range value, so our answer is D.

feet by 10 feet, and your dad plans to double its area by adding the same amount x to its length
and width. Find the value of x, and the new dimensions of the patio.

Answers

Answer:

x = 3.69 feet

11.69 x 13.69 feet

Step-by-step explanation:

new area = (8 x 10) x 2 = 160

(8 + x)(10 + x) = 160

80 + 8x + 10x + x² = 160

combine like terms:

x² + 18x - 80 = 0

factor:

(x - 3.69)(x + 21.69) = 0

x = 3.69

Answer:

x = 3.69 feet

11.69 x 13.69 feet

new area = (8 x 10) x 2 = 160

(8 + x)(10 + x) = 160

80 + 8x + 10x + x² = 160

combine like terms:

x² + 18x - 80 = 0

factor:

(x - 3.69)(x + 21.69) = 0

x = 3.69

Marco's goal is to eat only 2000 calories each day. One day for breakfast he consumed 310 calories, for lunch he consumed 200 more calories then breakfast, and for dinner he consumed 800. Did he make his goal? Explain

Answers

Answer:

no

he consumed only 1620 calories

Step-by-step explanation:

WE HAVE TO FIND THE SUM OF THE TOTAL CALORY

CALORIES CONSUMED IN THE MORNING = 310

CALORIES CONSUMED IN THE AFTERNOON = 310 + 200 = 510

CALORIES CONSUMED IN THE NIGHT = 800

Sum = 1620

he didn't reach is goal because he consumed only 1620 calories which is less than 2000

Jim and Becky wash cars. Jim charges 10$ plus 3$ per car. Becky charges 12$ plus 2$ per car. Write an equation to show when the charges for washing cars are equal

Answers

Answer:

10 + 3x = y is jims equation. 12 + 2x = y is beckys equation

Step-by-step explanation:

To find Jim and Becky's possible outcomes, you must make charts with x as the input value and y as the output value, such as the one below (NOT THE REAL CHART!!!!) . The way to do this is change the value of x on the equation with a number (usually in numerical order starting with 1 or 0) , and then solve that to find y.

You have to compare both charts to see where they make the same amount of money, and you can see that Jim and Becky make the same amount of money on some occasions. Please double check. I hope this helped! :]

The numbers of cookies in a shipment of bags are normally distributed, with a mean of 64

and 68 cookies?

Answers

Answer:

68% i think yeah?

The percent of bags of cookies will contain between 60 and 68 cookies is 68.29%.

What is standard deviation?

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

[tex]\mu[/tex]= 64,   [tex]\sigma[/tex]= 4,

[tex]Z_1[/tex]= [tex]X_1[/tex] - [tex]\mu[/tex]/  [tex]\sigma[/tex]

  = 60-64/4

  = -1

again,

[tex]Z_2[/tex]= [tex]X_2[/tex] - [tex]\mu[/tex]/  [tex]\sigma[/tex]

  = 68-64/4

  = 1

Thus, P( 60<X<68)

= p(-1<Z<1)

= 0.6829

= 68.29%
