Which College entrance exam has the least amount of math problems to work?

1 answer:

taurus [48]3 years ago

7 0

Answer:

SAT

Step-by-step explanation:

The two main college entrance exams are the SAT and ACT which are used for almost all colleges in the United States. Between these two the SAT has a lesser focus on math in general. Instead, the SAT tends to focus more on word problems and the process taken to solve them. This does not mean that it has no math at all, there is still a math section on the SAT's but it is not as extensive as in the ACT's.

£1400

A reduction of 40% means that £840 is 60% of the original price

Divide £840 by 60 to find 1% then multiply by 100 to find original price

original price = £840 × $\frac{100}{60}$ = £1400

A prism is dilated by a factor of 1. 5. How many times larger is the volume of the resulting prism than the volume of the origin

andre [41]

The volume of the resulting prism is 3.375 times of original volume.

<h3>What is a dilation or scale factor?</h3>

The factor by which the dimensions of an object are enlarged is called the scale factor.

Let us take the base area of Prizm = a²

Height of the prism = h

Enlarged area = (scale factor)² * previous area

Enlarged area = 1.5²*a² = 2.25a²

Enlarged height = 1.5h

So, enlarged volume = enlarged area* enlarged height

Enlarged volume= 2.25a²*1.5h = 3.375a²h

Enlarged area/previous area = 3.375a²/a² = 3.375

Therefore, the volume of the resulting prism is 3.375 times of original volume.

Which of the following is a factor of 7x2 - 12x - 4? (6 points)

grin007 [14]

Answer:

We conclude that 'None of the above' is the correct answer.

Step-by-step explanation:

Given the expression

$7x^2\:-\:12x\:-\:4$

Breaking the expression into groups

$7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)$

Factor out $x$ from $7x^2\:+\:2x$

$=x\left(7x+2\right)$

Factor out -2 from $\left(-14x-4\right)$

$=-2\left(7x+2\right)$

so the expression becomes

$7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)$

$=x\left(7x+2\right)-2\left(7x+2\right)$

Factor out the common term $7x+2$

$=\left(7x+2\right)\left(x-2\right)$

Therefore, from the given options, we conclude that 'None of the above' is the correct answer.
