8 0

Step-by-step explanation:

First, you have to add 8 + 7 + 5 all together, which would give you 20.

Then, you have the ratio of 8:20

But you have to simplify 8:20, by 2, which would give you 4:10

Also, simplifying by 4 is also possible, this would also give you 2:5

Overall, 8:20 is your answer

So it would be (B) & (E)

slavikrds [6]

Answer:

  • <u>115 dB</u>

Explanation:

<u>1. Given equation:</u>

\beta =10log(\frac{I}{I_0})\\\\ I_0=10^{-12}W/m^2

<u>2. Given intensity:</u>

I=0.315W/m^2

<u>3. Decibels</u>

\beta =10log(0.315/10^{-12})\\ \\ \beta =10log(315,000,000,000)\\ \\ \beta =10(11.498)=114.98\approx 115

Triangle ABC is an isosceles triangle. Angles B and C are base angles, with measurements of (11x −10)° and (7x + 10)°, respectiv
Ulleksa [173]

Answer:

m∠A = 90°

Step-by-step explanation:

In isosceles triangle base angles are congruent. That means we can equate measurments of angle B and angle C and solve for x!

m∠B = m∠C

11x - 10 = 7x + 10

4x - 10 = 10

4x = 20

x = 5

Now let's insert x back in the expressions for angles.

m∠B = (11x − 10)° = (11(5) − 10)° = 45°

m∠C = (7x + 10)° = (7(5) + 10)° = 45°

<u>Sum of all angles in the triangle is 180°.</u> Let's make an equation.

m∠A + m∠B + m∠C = 180°

m∠A + 45°+ 45° = 180°

m∠A  = 90°

Which of the following are solutions to the equation below (5x+1)^2=7?<br><br> Check all that apply.
stiv31 [10]
(5x+1)² = 7; expand: 25x² + 10x +1 = 7 or 25x² + 10x -6 = 0

Solve this quadratic for x:

x = [-b + √(b² - 4ac)]/2a and x = [-b - √(b² - 4ac)]/2a
Plug the values and you'll find :
x = (- √7 - 1)/5 (answer C)
x = (+√7 -1)/5  (answer E)

What is the rate of change shown in the graph
ahrayia [7]

Answer:

-4/3  (Answer A)

Step-by-step explanation:

Here we go from the point (-3, 3) on the left to the point (0, -1) on the right.  It is immediately apparent that x (the run) increases by 3 from -3 to 0 and that y (the rise) decreases by 4 from 3 to -1.  Thus, the slope of this line (which is also the rate of change) is

m = rise / run = -4/3  (Answer A)
