Answers

Answer 1

Answer:

zero

Answer:

Step-by-step explanation:

the distance a plane travels between two cities is 260 miles. The same trip, in miles, traveled by car is approximately 10% greater due to the route traveled. If the car travel at an average rate of 55 miles per hour, approximately, how long will it take the car to travel between the same two cities?

Answers

Answer:

5.2 hours or 312 minutes

Step-by-step explanation:

The plane route has been given as 260 miles.

We're told that the car/road rouge is 10% longer, and that is 260 * 1.1, which is equal to 286 miles.

Now, the car travels at 55 miles per hour, and we're to calculate how long it will take to travel.

Speed = distance / time

Making time the subject of formula, we know that

Time = distance / speed

Time = 286 miles / 55 miles per hour

Time = 5.2 hours, converting to minute, we have 5.2 * 60 = 312 minutes.

When Georgia started Kindergarden, her parents set aside $10,000 in an account that yielded 5.6% interest compounded annually to pay for her college tuition. After 6 years of elementary school, 3 years of middle school and 4 years of high school, how much was in the account for Georgia’s college tuition?

Answers

The right answer is b

Answer:

17,280

Step-by-step explanation:

first, you find 5.6 % of 10,000 which is 560. Then you have to figure out how many years the interest was coming in which is 13 years. you multiply the 560 by 13 years to get 7,280 and add that to 10,000. that's how you get your final answer of 17,280

find the measure of angle 7

Answers

Answer:

63°

Step-by-step explanation:

Knowing that opposite angles are equivalent, we can easily say that ∠3 is equivalent to 63°. ∠1 and ∠4 are the complements of the given angle and ∠3, so their measures are also the same and are equivalent to 180°-63°=117°.

Since the two horizontal lines are parallel, ∠6 is equivalent to ∠3, so it too is 63°. Its complements, ∠5 and ∠8, are thus equivalent to the complements of ∠1 and ∠4, and thus they are 117°. Lastly, since opposite angles are equivalent, ∠6 is equivalent to ∠7, and so ∠7 is also 63°.

the answer is 63degrese

The Marching band enters the gym and marches across the gym without turning. Which of these describes the transformation?
A. Dilation
B. Reflection
C. Rotation
D. Translation

Answers

Answer:

The answer is not c, it is b.

Step-by-step explanation:

They do not turn, so it is just a reflection. They are mirroring where they were before they moved.

Transformation involves changing the position of an object.

The transformation in this scenario is translation

From the question, we understand that:

The marching band marches across the gymAnd they did not turn

The above points simply mean that, they moved across the gym in a straight direction.

A movement on a straight line represents translation.

Hence, the correct transformation is (d) Translation

What is the surface are of the cylinder with a height 7ft and radius 3ft?

Answers

Answer:

Total area, including top and bottom: 67.7 ft²

Step-by-step explanation:

The area of the sides (only) is A = (circumference of base)(height of cylinder), and in this case A = 2(3 ft)(3.14), or

approximately A = 18.8 ft²

If you also want the areas of the base and top of the cylinder, perform the indicated calculations:

A (top and bottom) = 2π(3 ft)² = 48.9 ft²

So that the total surface area is (48.9 + 18.8) ft², or 67.7 ft²

1. Three apples, a, and two peaches, p, sell for $1.25.
Five apples and 1 peach sell for $1.50. What is the
cost of one apple?

Answers

Answer:

$0.25

Step-by-step explanation:

You can use systems of equations to solve this.

3a+2p = 1.25

5a+p = 1.5

Multiply the second equation by 2.

3a+2p = 1.25

10a+2p = 3

Subtract the bottom from the top

-7a= -1.75

Divide by -7

a= 0.25

Each apple is $0.25 (in this case, the peach also costs $0.25)

The dimensions of a rectangle are 2 x − 5 and 3 x + 3 . Which expression represents the area of the rectangle in simplest terms? A. 6 x 2 − 9 x − 15 B. 6 x 2 − 9 x + 15 C. 6 x 2 + 9 x − 15 D. 6 x 2 − 15 x − 9

Answers

Answer:

Step-by-step explanation:

The area of a rectangle is the product of its dimensions, that is

A = (2x - 5)(3x + 3) ← expand using FOIL

= 6x² + 6x - 15x - 15 ← collect like terms

= 6x² - 9x - 15 → A

Polly and her friend, Goofus, are making friendship bracelets. The have 3 yards of thread that they need to cut into pieces that are 1/8 of a yard long. How many bracelets can they make from their yarn?

Answers

Answer: 24 bracelets.

Step-by-step explanation:

This question is about the division of numbers.

Since there are 3 yards of thread that is needed to be cut into pieces that are 1/8 of a yard long, this means that we've to divide 3 yards by 1/8. This will be:

= 3 ÷ 1/8

= 3 × 8

= 24

Therefore, they can make 24 bracelets from the yarn.

Josie is picking apples. She has 3 identical baskets that she is trying to fill. One basket is 3/5 full, another is 7/10 full, and the last is 2/3 full. What portion of the 3 baskets has Josie filled? Give you answer as a mixed number and as an improper fraction.

Answers

Answer:

1 29/30 full

Step-by-step explanation:

Basket 1 = 3/5 full

Basket 2 = 7/10 full

Basket 3 = 2/3 full

Total = 3/5 + 7/10 + 2/3

= (18+21+20) / 30

= 59/30

= 1 29/30 full

Therefore, the portion of the 3 baskets Josie has filled is 1 29/30

Step-by-step explanation:

p=c(1+r)^t

p=4,000(1+.04)^t

p=4,000(1.04)^t

p=4,000(1.04)^4
