A family’s vacation destination is 850 miles from their home. They travel by car 6 hours on the first day of their trip. Their average speed is 45 miles per hour. The next day they travel 7 hours, averaging the same speed. How many miles are left for the family to travel?

Answers

Answer 1

Answer:

The distance traveled is equal to the product of the speed and the time. For the first day,

                                     d = (45 mile/h)(6 h) = 270 miles

On the second day,

                                     d = (45 mile/h)(7 h) = 315 miles

The total distance traveled after 2 days is equal to 585 miles. Subtracting this value from the given distance will give us an answer of 265 miles.  

Step-by-step explanation:

Answer 2

6x45=270, 7x45=315, 270+315=585, 850-585=265

265 miles left

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

For two figures to be considered congruent, their corresponding sides and angles must all be the same. Congruence can occur in any geometric figures, from simple line segments to complicated shapes with many sides and angles. Here’s another way to think about congruence: if you cut two figures out of paper, you could place one cutout on top of the other cutout and it would disappear. Consider that geometric figures are made up of an infinite number of points. When superimposed on top of each other, all of the points in one figure would match up with all of the points in the other figure.

According to the passage, which of the following is not true?

A
Paper cutouts can be used to determine congruence.

B
Congruent figures have exactly the same size and shape.

C
Congruence only happens in three- or four-sided figures.

D
Two octagons can be congruent if their corresponding sides and angles match up.

to find the perimeter you add up all the sides and since it's a square and squares have all four equal sides

you just divide 100/4=25

4 sides of a square. Each side of a square is equal. You said the perimeter is 100. So if we put it in an equation, lets say S = Side. 4s=100. Now we just divide. s=25

answer asap please and thank you ​

Answers

Answer:

\(6\frac{1}{2}\)

Step-by-step explanation:

When given the following problem:

\(7\frac{1}{7}-\frac{9}{14}\)

Convert the first mixed number to an improper fraction. This can be done by multiplying the "number" part of the mixed number by the denominator of the fraction, the number under the fraction bar. Then add the result to the numerator.

\(\frac{50}{7}-\frac{9}{14}\)

To perform this operation, one must ensure that both denominators have the same value. Multiply the numerator and denominator for the first fraction by (2), so that the denominators of both fractions is (14),

\(\frac{100}{14}-\frac{9}{14}\)

Perform the operation, subtract one numerator from the other, leave the denominators the same,

\(\frac{91}{14}\)

Simplify, divide the numerator by (14) (the denominator), write the whole part as the "number" part of the mixed number. Then write the remainder on top of the fraction bar.

\(6\frac{7}{14}\)

Reduce, divide the numerator and denominator by a common fraction,

\(6\frac{1}{2}\)

Convert the mixed numbers to improper fractions, then find the LCD and combine.

Which of the following best represents this situation?



A. 750 + 0.15x = 675 + 0.20x

B. 750 + 0.20x = 675 + 0.15x

C. 750 + 0.15x > 675 + 0.20x

D. 750 + 0.15x < 675 + 0.20x

Answers

it’s C i think cause it’s saying it offers $675 more so > is the more sign

Answer:

x - would be the total value of merchandise sold

y - would be her take home pay would be

Job A: y = 0.15x + 750

Job B: y = 0.20x + 675

We want to know when job B's pay will be larger than job A's pay. So set the expression for job B larger than job A, solve for x

0.20x + 675 > 0.15x + 750

0.20x - 0.15x > 750 - 675

0.05x > 75

x > 75/0.05

x > 1500
