15.

Start with the first parenthesis inside the box 11-6.

Doing the math, that comes out as five. Now you have to square it to get 25 before dividing it by 5 again to receive 5.

After that, multiply by 3 to get 15 as your final answer.

Hope this helps!

Step-by-step explaination

All you need to do is find the frequency of the test scores.

70 = 2 dots

75 = 0

80 = 3 dots because there are 3 students that got a 80 %

85 = 3 dots because there are 3 students that got a 80 %

90 = 4 dots because there are 4 students that got a 90 %

95 = 3 dots

100+ = 0 dots

6th grade math (answer both) .... :D

Answer:

Question 2: Option B

Step-by-step explanation:

The number of ounces and the total price for yogurt cup A is not stated, therefore, I can not answer question 1 properly.

<h3>For question 2:</h3><h3 />

Unit rate formula for price is: $\frac{price}{quantity}$

32 ounces of yogurt sell for 1.62.

So:

$\frac{1.62}{32} =0.050625$

0.050625 ≈ 0.05

<em>Option B should be the best answer. </em>

Quadratic equations: Factoring

stellarik [79]

Remember
if ab=0, then assume that a and b equal 0

factor out common term
comon term in 6x^2 and 15x is 3x
3x(2x)+3x(5)=0
3x(2x+5)=0
set each to zero
3x=0
x=0

2x+5=0
2x=-5
x=-5/2

x=-5/2 and 0

Answer:

1. $\sqrt{74}$ ft 2. $50\sqrt{2}$ yards 3. $5\sqrt{35}$ units.

Step-by-step explanation:

Pythagorean's Theorem $a^2 + b^2 = c^2$

A and b are both side lengths, c is the hypotenuse.

7^2 + 5^2 = 74

sqrt(74) is the answer for 1.

30^2 - 5^2 = 875

Simplify the radical. sqrt(875) --> 5sqrt(35). The answer for three.

There's a rule in geometry that says a diagonal of a square is the same length as taking a side length times the square root of two. There's your answer for two.
