Which expression is equivalent to 46 ⋅ 4−8?

1 answer:

7 0

Let's do 46 * 4 - 8 first to get 176.

The first 2 will be less than 1\4 (powering a fraction reduces it) so they are wrong
42 and 414 aren't equal to 176 soooo.....

None of the above?

Hope this helps!

A mixture of 30 pounds of candy sells for $1.10 a pound. The mixture consists of chocolates worth $1.50 a pound and chocolates w

Allushta [10]

Answer: Option 'B' is correct.

Step-by-step explanation:

Number of pounds of candy = 30

Cost per pound = $1.10

Total amount would be

$30\times 1.10\\\\=33$

Let the number of pound that sold at $1.50 per pound be 'x'.

Let the number of pound that sold at 90 cents per pound be '30-x.

According to question, we get that

$1.5x+0.90(30-x)=33\\\\1.5x+27-0.90x=33\\\\1.5x-0.9x=33-27\\\\0.6x=6\\\\x=\dfrac{6}{0.6}=10$

Hence, there are 10 pounds of chocolates worth $1.50 per pound.

Therefore, Option 'B' is correct.

Sphere A and Sphere B , are similar. The volumes of A and B, are 17 and 136 cubic centimetres, respectively. The diameter of B ,

xxMikexx [17]

Answer:

Step-by-step explanation:

Given: Sphere A and Sphere B are similar.

The volumes of A and B are 17 $cm^3$ and 136

The diameter of B is 6 cm.

To find: diameter of A

Solution:

Let R denotes radius of sphere A and r denotes radius of sphere B.

Radius of sphere A= R

Diameter of sphere B = 6 cm

So, radius of sphere B (r) = $\frac{6}{2}=3\,\,cm$

Volume of sphere is $\frac{4}{3}\pi(radius)^3$

Volume of sphere A = $\frac{4}{3}\pi(R)^3$

$\frac{\frac{4}{3}\pi R^3}{\frac{4}{3}\pi r^3}=\frac{17}{136}=\frac{1}{8}\\\frac{R^3}{r^3}=\frac{1}{8}\\\frac{R}{r}=\frac{1}{2}\\r=2R$

Put r = 3 cm

$3=2R\\R=\frac{3}{2}=1.5\,\,cm$

Diameter of sphere A = 2 × Diameter

= 2 × 1.5

=3 cm
