Answer:

A. 3.7, because |3.7| = 3.7

Step-by-step explanation:

What the question is referring her by magnitude is units away from 0. 3.7 is 3.7 units away from 0, which is the same thing as the absolute value of 3.7. And since absolute value is always positive, C is already out. D is also out as the value doesn't change. B's reason contradicts the answer, so it is also wrong. This leaves A (3.7, because |3.7| = 3.7) as our answer.

Agata [3.3K]

Answer:

Adult tickets = 84

Children tickets = 33

Step-by-step explanation:

At a play 117 tickets were sold.

Adult's tickets (a) cost $2.50 each and,

Children's (c) tickets cost $1.00 each

Money collected = $243

This is the simultaneous equation formed:

a + c = 117 ... (i)

2.5a + c = 243 ... (ii)

Subtracting (ii) - (i) we get;

1.5a = 126

a = 126 ÷ 1.5 = 84

So there were 84 adult's tickets sold and 117 - 84 = 33 children's tickets sold.

Answer:

$\boxed{\sf 43.35 \ cm}$

Step-by-step explanation:

Apply formula for the circumference of a circle.

$\sf C=\pi d$

The diameter $\sf d$ is 13.8 cm.

$\sf C=\pi (13.8)$

$\sf C= 43.3539786195...$

$\sf{C} \approx \sf{43.35}$

What is the area of a rectangle that is 3.1 cm wide and 4.4 cm long? Enter the full-precision answer first to see the correspond

Brrunno [24]

Answer: Without rounding : 13.64 (square cm)

Rounded answer : 13.6(square cm)

Step-by-step explanation:

We know that the area of a rectangle is given by :-

$A=l\times w$ , where l is the length and w is the width of the rectangle.

Given : The dimensions of a rectangle are 3.1 cm wide and 4.4 cm long.

Then, the area of rectangle will be:-

$A=4.4\times 3.1=\dfrac{44}{10}\times\dfrac{31}{10}\\\\=\dfrac{1364}{100}=13.64\text{ cm}^2\approx13.6\ cm^2 \text{Rounded to the nearest tenth}$

Therefore, the area of rectangle = $13.6\text{ cm}^2$

Bob needs to make a canvas sun shade that covers half of the pool. One side of the pool is 31.22 feet and the other side is 25 f

lidiya [134]

To find the diagonal of the pool, you need to use The Pythagorean Theorem which is a^2 + b^2 = c^2. We need to find c, so we substitute in the sides, and it doesn't matter how we substitute because we are adding positive numbers so the answer will always be the same. So, 31.22^2 + 25^2 = c^2. After we calculate this out we get c^2. To find the diagonal or c, we square root c^2 to get a final answer of 39.9961 or 40 feet
