1. 624 students

If you multiply .24 (24%) by 2600, you'll find that the answer is 624.

2. 11% increase in protein

Divide 48 by 54 (48 ÷ 54), you'll notice the answer is around 0.88888. Next subtract 0.88888 by 1. The answer will be around 0.11111.

3. 44% sale

Divide 200 by 360 (200 ÷ 360). The answer will be around 0.5555555556. Next, subtract this number from 1. THIS answer is equal around 0.4444444.

4. 9 players were NOT eligible

Multiply 60 by 0.85 (85%). The answer to this is 51. Subtract 51 from the original number (60). The answer is 9.

5. 420 students plan to go to college

Multiply 1200 by 0.35 (35%). The answer to this is 420.

6. 20% don't have an Instagram account

To make this easier, we'll double to statistics (instead of 4 out of 5, it's 8 out of 10). 8 divided by 10 = 0.8. Subtract 0.8 from 1. Now, you have you're answer: 0.2 or 20%.

I hope this helps! Sorry if some were incorrect. :)

Approximate the area between the xxx-axis and h(x) = \dfrac{1}{7-x}h(x)= 7−x 1 ​ h, (, x, ), equals, start fraction, 1, divided
tiny-mole [99]

Answer:

\dfrac{47}{60} sq. units.

Step-by-step explanation:

The given function is

h(x)=\dfrac{1}{7-x}

We need to find the area between x-axis and the given function from x=2 to x=5.

Left Riemann sum formula of area:

Area=\sum_{n=0}^{N-1}f(x_n)(\Delta x_n)

For given question,

Area=\sum_{n=2}^{5-1}f(x_n)(\Delta x_n)

Area=\sum_{n=2}^{4}f(x_n)(\Delta x_n)

Area=f(x_2)(3-2)+f(x_3)(4-3)+f(x_4)(5-4)

Now,

Area=\dfrac{1}{7-2}\times (1)+\dfrac{1}{7-3}\times (1)+\dfrac{1}{7-4}\times (1)

Area=\dfrac{1}{5}+\dfrac{1}{4}+\dfrac{1}{3}

Area=\dfrac{12+15+20}{60}

Area=\dfrac{47}{60}

Therefore, the required area is \dfrac{47}{60} sq. units.

Which transformations will produce similar, but not congruent, figures?
navik [9.2K]
B) Parallelogram JKLM is translated and then dilated
as well as c
C) Parallelogram JKLM is dilated and translated

C is the best answer because is size is changing. In all the others nothing is changing except the position which remains congruent and similar but C does not . The sizes changes which makes them not congruent but still similar.
