Answer:

61.8 miles/hr

Step-by-step explanation:

Given that

Dennis starts from Boston and travels to Hartford for 101 miles.

And then he travels towards Baltimore which is 410 miles away from Boston.

Time taken from Hartford to Baltimore = 5 hours

Kindly refer to the image attached for the trip of Dennis and the distance traveled by him.

Point A represents Boston.

Point B represents Hartford.

Point C represents Baltimore.

Distance AB = 101 miles

Distance AC = 410 miles

Actually, we are given that Distance BC is traveled in 5 hours.

Distance BC = AC - AB = 410 - 101 = 309 miles

Average Speed is given as:

[tex]\text{Average Speed = }\dfrac{\text{Total Distance traveled}}{\text{Total Time Taken}}[/tex]

So,

[tex]\text{Average Speed = }\dfrac{309}{5}\\\Rightarrow \text{Average Speed = }\bold{61.8\ miles/hr}[/tex]

We are given the equation:

√10(128 + 2)

We can simplify what is in parenthesis.

√10(130)

We can put the number in parenthesis on the left side of the square root.

130√10

As a decimal, it would equal approximately 411.10

Answer:

460

Step-by-step explanation:

8x220=1760

5x200=1000

(2760+x)/14=230

2760+x=3220

x=3220-2760

x=460

Answer:

$3,000

Step-by-step explanation:

To find his average monthly pay, you have to find the total amount that Willian received in a year by multiplying his monthly salary as a teacher for 10 months and his salary as a barista for 2 months and adding up these numbers. Then, you have to divide the total amount he earned by 12 that is the number of months in a year:

($3,200*10)+($2,000*2)= $32,000+4,000=36,000

$36,000/12=$3,000

According to this, his average monthly pay for the 12 months was $3,000.

Step-by-step explanation:

given data:

total beans = 9

blue beans = 6

red beans = 1

yellow beans = 1

green beans = 1

solution:

This is a permutation problem because there is a condition attached to it which states that the beans most be arranged in a way that atleast each none blue has a blue bean on its side when shared.

= ( r + n - 1 ! ) / r ! ( n - 1 )!

= 3 + 6 - 1 / 3! ( 6-1 )!

= 8! / 3! x 5!

= 40320/ 720

Answer:

w = -12

Step-by-step explanation:

10 – 11w + 12w = -2

Combine like terms

10 +w = -2

Subtract 10 from each side

10+w-10 = -2-10

w = -12

Answer:

w = -12

Step-by-step explanation:

10 – 11w + 12w = -2

10 + w = -2

subtract 10 on both sides

w = -12

Answer:

6 with a reminder of 2 :)

4 is the quotient and 2 is the remainder when 26 divided by 4.

A division is a process of splitting a specific amount into equal parts.

The number which we divide is called the dividend.

The number by which we divide is called the divisor.

The result obtained is called the quotient.

The number left over is called the remainder.

26 divided by 4

26 is the dividend

4 is the divisor

26/4

26 we can split as 24+2

24 is divided by 6 which results 4 and 2 is the remainder. So 4 is the quotient and 2 is the remainder

Hence, 4 is the quotient and 2 is the remainder when 26 divided by 4.

Let roses be R and carnations be C

"in a ratio of 2 to 7" means that the ratio of R to C is 2 to 7, meaning you'll have to cross multiply to translate it algebraically

[tex]R:C\\2:7\\7R=2C\\[/tex]

since C = 343 we plug 343 in [tex]7R=2C[/tex]:

[tex]7R=2(343)\\7R=686\\R=\frac{686}{7} \\R=98[/tex]

ergo, she needs 98 roses

to make sure of the answer:

"ratio of 2 to 7" is technically a fraction =>  [tex]\frac{2}{7}[/tex]

and since the ratio of the roses to the carnations is the same as [tex]\frac{2}{7}[/tex] we plug the values R = 98 and C=343:

[tex]\frac{R}{C}=\frac{98}{343}=\frac{2}{7}[/tex]

False: equilateral triangle has 3 equal sides and 3 equal angles measure 60 degrees

Answer:

True

Step-by-step explanation:

In an equilateral triangle, all sides are equal in length.

That means that all the angles of the triangle will be congruent.

Since a triangle has 3 angles that always add up to 180 degrees, each angle is 60 degrees.

(180/3=60)

A right triangle must have one 90 degree angle.

An obtuse triangle must have an angle that is greater than 90 degrees.

An acute triangle's angles must all measure 89 degrees or less.

Hence, the given statement is true.

Equilateral triangles can be classified as acute.

Answer:

15/8

Step-by-step explanation:

one big rectangle is 1 or 8/8 and the other is 7 out of 8, therefore we have 8/8+7/8 = 15/8.

You are required to find the fraction of the rectangle shaded gold in the two rectangles

The fraction that was shaded in the two triangles is 15/8

Each of the rectangles are divided into 8 equal parts

The first rectangle has 8 equal sections

The second rectangle also has 8 equal sections

out of the 8 equal sections in the first rectangle, 8 was shaded gold

Then, we have 8/8 shaded = 1 whole

out of the 8 equal sections in the second rectangle, 7 was shaded gold

Then, we have 7/8 shaded

Improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (down number)

Therefore, rectangle 1 + rectangle 2

= 8/8 + 7/8

= (8+7) / 8

= 15/8

Answer:

FV= $95,454.20

Step-by-step explanation:

Giving the following information:

Annual deposit= $2,000

Number of periods= 25 years

Interest rate= 5% compounded annually

To calculate the future value of the annual deposits, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

FV= {2,000*[(1.05^25) - 1]} / 0.05

FV= $95,454.20
