what does scholarship mean to you? (must use at least 1 paragraph

Answers

A scholarship is an opportunity of a lifetime for someone who might be otherwise unable to attend a college or university. For me it is motivation to strive in my education process and always reach for higher goals. It is an ability for me to achieve my dreams and it is awarded to me through my ambition, heart, and motivation.

(you might want to tweak this to fit you and make it longer but this is the best i got)

I think a scholarship means an opportunity for people to earn an education. Without assistance from an outside source, students may have trouble paying for the degree. Scholarships help students have more time to focus on their studies. For many students, the stresses of working make it difficult for them to graduate on time, or graduate with the high grades they have the potential to achieve. For other students, the work/study life is unsustainable, and they discontinue their studies altogether. And I think scholarships can fill the gap. I feel with the assistance it can support students who fall in the gap between high and low-income levels.

Item cost $490 before tax, and the sales tax is $24.50

Find the sales tax rate right your answer as a percentage


please help me :’)

Answers

Answer: 5%

Step-by-step explanation:

Item Cost - $490

Tax - $24.50

Tax/Price = 24.50/490.00 = 0.05

0.05 *100 (for percent) = 5%

Check your work:

490.00*0.05 = 24.50

Ayanna plans to bake 3 types of cookies to take to a party. She needs to be sure that she has enough flour. The chocolate cookies use
1 3/4
cups of flour, the sugar cookies use
3 2/3
cups of flour, and the oatmeal spice cookies require
1 7/8
cups of flour. Which is the BEST estimate of the total amount of flour she will need?

Answers

The children brought 2+1+114=414 cups of flour and 14+12+34=112 cups of butter.

They have enough flour for

414÷34===174×43173523
batches and they have enough butter for

112÷13===32×3192412
batches, so the butter is the limiting factor. Thus, they can make 4 whole batches of a dozen cookies each.
Since you need an estimate, you can round up the cups of Fluor you need. So, 1 3/4 rounds to 2 cups, 3 2/3 rounds to 4 cups and 1 7/8 rounds to 2 cups.
2+4+2 = 8 cups is the best estimate

C) The distance between the heights of the pelican and heron is -33 feet.

D) The difference in height between the pelican and the trout is -40 feet.

E) The difference in height between the pelican and the trout is 40 feet.

F) The distance between the heights of the pelican and the trout is 40 feet.

Answers

Answer:

[A] The difference in height between the pelican and the heron is -33 feet.

[E] The difference in height between the pelican and the trout is 40 feet.

[F] The distance between the heights of the pelican and the trout is 40 feet.

Step-by-step explanation:

Note: 0 the sea level.

Since the heron is perched in a tree 50 feet above sea level and directly below the heron the pelican is flying 17 feet above sea level, you can find the difference in height between the pelican and the heron by subtracting 50 feet from 17 feet.

Then, you get that this is: 17-50= -33 feet

Now, according to the information given in the exercise, you know that the trough is swimming directly below them and its height is 23 feet below sea level. If you represent this with an integer, this is: -23

Therefore you can find the difference in height between the pelican and the trout through the following subtraction:

17-(-23)=17+23=40  feet.

Hence, distance = 40 feet.

Answer: To find the area for a parallelogram use the formula A=bh

Step-by-step explanation:

The area of the parallelogram is 32cm.

Since the area of the parallelogram equals base times height, you have to find the base of the parallelogram which, is 8, and then find the height, which is 4.

Then multiply them to get your answer.

Base = 8

Height = 4

8cm x 4cm = 32cm

So, the area of the parallelogram is 32cm.

Explain why you cannot factor the trinomial x(to the power of 2)−12x+6

Answers

Answer:

See below

Step-by-step explanation:

You cannot find two whole number integers that give a sum of -12 and a product of 6.

-1 + -11 = -12, but (-1)(-11) = 11, which isn't 6

-2 + -10 = -12, but (-2)(-10) = 20, which isn't 6

...and so on...

x² - 12x + 6

This is in the form of ax² + bx + c.

We can not factorize because b < ac.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

x² - 12x + 6

This is in the form of ax² + bx + c.

Middle-term factorization.

We can not use middle-term factorization because b < ac.

Where a = 1, b = -12 and c = 6

Now,

Using determinant.

x² - 12x + 6

It is in the form of ax² + bx + c

a = 1, b = -12, and x = 6

So,

x = -b ± √(b² - 4ac) / 2a

x = 12 ± √(144 - 24) / 2

x = 12 ± √120 / 2

x = 12 ± 2√30 / 2

x = 6  ± √30

x = 6 + √30 and x = 6 - √30

Thus,

The solutions are x = 6 + √30 and x = 6 - √30.

Sum of interior angles of a triangle = 180°

⇒ 10x + 8 + 52 + 2x = 180

⇒ 12x = 120
