Answer: 63

Step-by-step explanation:

If she made a goal score of 33 and the ratio of goals and misses is 11:10 that means the answer is 30 because the actual amount of goals is 3 times the amount on the ratio. So you would just have to multiply it by 3.

Find the equation of a line given the point and slope below.

Levart [38]

Step-by-step explanation:

$\frac{y - 6}{x - 3} = - 3$

$- 3(x - 3) = y - 6$

$- 3x + 9 = y - 6$

$y = - 3x + 9 + 6 = - 3x + 15$

A circular mat has a circumference of 220 centimeters. Find the radius rounded to the nearest whole number.

Papessa [141]

С = 2πr [π≈3.14]

220 = 2 * 3.14 * r
220 = 6.28r
r = 220/6.28 ≈ 35 cm ← <span>to the nearest whole number.</span>

Simplify. 3725−−√−2825−−√+6325−−√ 457√ 7√ 257√ 857√

Andru [333]

Answer:

Option A.

Step-by-step explanation:

Consider the given problem is

$3\sqrt{\frac{7}{25}}-\sqrt{\frac{28}{25}}+\sqrt{\frac{63}{25}}$

Using the properties of radical expressions we get

$3\cdot \frac{\sqrt{7}}{\sqrt{25}}-\frac{\sqrt{28}}{\sqrt{25}}+\frac{\sqrt{63}}{\sqrt{25}}$ $[\because \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}]$

$3\cdot \frac{\sqrt{7}}{\sqrt{25}}-\frac{\sqrt{4}\sqrt{7}}{\sqrt{25}}+\frac{\sqrt{9}\sqrt{7}}{\sqrt{25}}$ $[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]$

$3\cdot \frac{\sqrt{7}}{5}-\frac{2\sqrt{7}}{5}+\frac{3\sqrt{7}}{5}$

Taking out common factors.

$\frac{\sqrt{7}}{5}(3-2+3)$

$\frac{\sqrt{7}}{5}(4)$

$\frac{4\sqrt{7}}{5}$

The simplified form of given expression is $\frac{4}{5}\sqrt{7}$

Therefore, the correct option is A.

Find the value of BC. HELP PLEASE!!

Masteriza [31]

It's an equilateral triangle, therefore

AB = BC = BA

We have the equation:

$\dfrac{3}{2}x-12=\dfrac{1}{2}x-2\qquad\text{multiply both sides by 2}\\\\3x-24=1x-4\qquad\text{add 24 to both sides}\\\\3x=x+20\qquad\text{subtract x from both sides}\\\\2x=20\qquad\text{divide both sides by 2}\\\\x=10$

$BC=BA\to BC=\dfrac{1}{2}(10)-2=5-2=3$

<h3>Answer: BC = 3</h3>
