Answer:

The lake is 75 ft deep

Step-by-step explanation:

Here , we want to get the depth of the lake

mathematically, we can have this as the rate at which the elevation of the probe changes multiplied by the time it took the probe to reach the bottom of the lake

That would be;

3/2 * 50 = 75 feet

Answer:

8 is the number

Step-by-step explanation:

So in order to find out the "number" we are going to have to turn the equation around. First of all the equation says "minus 15 is equal to 41" so we are going to add 15 to 41:

41 + 15 = 56

So now we are going to divide 7 from 56 because we are doing the equation backwards:

56/7 = 8

So now we check our work by replacing the number in the sentence with eight, "7 times 8 minus 15 is equal to 41" which would make the equation look like this:

7 * 8 + 15 = 41

First we multiply 7 by 8:

7 * 8 = 56

Now we subtract 15 from 56:

56 - 15 = 41

Making the equation look like this:

41 = 41

The value of x in the diagram is 7 (D) because 2 * 7 = 14 and 7 * 7 = 49.

The value of x in the given diagram will be 7.

Similar triangle are those which have two pairs of interior corresponding angles are equal.

We have,

Two triangles as shown in the given figure,

Now,

Both the given triangles have 90° corresponding angles and also the opposite angle of 90° of both triangles is equal.

So,

Using triangle similarity rule,

i.e.

Sides are in equal proportion,

i.e.

[tex]\frac{49}{x} =\frac{14}{2}[/tex]

⇒

14x = 49 × 2

14x = 98

[tex]x=\frac{98}{14}[/tex]

x = 7

Hence, we can say that the value of x in the given diagram will be 7.

Answer:

y=4/3x+0

Step-by-step explanation:

slope intercept form works right?

y=mx+b

the m is the slope, and the problem gives us the slope. (4/3)

the b is the y intercept (where the line goes through the y) so on our coordinates, the second number is the y, so we have y=4/3x+b

The slope of the line passing through (-4, -3) and (14, 0) is 1/6.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

The slope of the line passing through (-4, -3) and (14, 0) is:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{0-(-3)}{14-(-4)} \\\\m=\frac{3}{18} \\\\m=\frac{1}{6}[/tex]

Answer:

Negatively Correlated

Step-by-step explanation:

Number of video games played is likely to be negatively correlated to student's grade.

Negative correlation means that the variables deviate in opposite directions, one variable increase (decrease) & other variable decrease (increase).

As more video games played implies lower student grade, less video games played higher student grade. So, the variables are negatively correlated.

Whether the variables are strongly negatively correlated (correlation coefficient > 0.5) or weekly correlated (correlation coefficient < 0.5). It depends on how severely video games affect student's performance.

f(-10)=105

Step-by-step explanation:

When something says f(x), the (x) is your plugin value. So basically in this scenario, x= -10

    1) f(-10)= (-10)^2+5

    2)f(-10)= 100+5

    3) f(-10)= 100+5

Ok hopefully I remembered my properties of exponents correctly, but I'm pretty sure that's the answer. If it isn't, you should try making the 100 negative instead of positive from step 2 and work from there.

B 9/14

Step-by-step explanation:

First, we have to find the product by doing the multiplication.

9/10 x 5/7 = 45/70

We have to find the greatest common factor that both the numerator and the denominator share to divide them by which is 5.

We can simplify 45/70 by dividing both the numerator and the denominator by 5.

This will give us 9/14.

We also know that this fraction cannot be simplified anymore since we took the greatest common factor that both the numerator and the denominator shared.

Therefore the answer is B 9/14

Answer:

1) C=80°

2) A=C= 54°

Step-by-step explanation:

1) 180-60-40=80

2)180-72=108

108/2=54

Hope this helps! :)

Answer:

1. 80º

2. Both are 54º

Step-by-step explanation:

1. If you add 60º + 40º in problem 1, you get 100º. We need to get it to equal 180º, so this means the missing angle would be 80º

2. Just like in the first one, we need this to equal 180º. So, let's go backwards.

180 - 72 = 108

Now, since the remaining angles are equal, let's divide 108º by 2

108 / 2 = 54º

Hope this helps :)

Answer:

180° - t = 5 · ( 90° - t )

180° - t = 450° - 5 t

5 t - t = 450° - 180°

4 t = 270°

t = 270° : 4

t = 67.5°

The measure of an angle is 67.5°.

Its complement angle: 22.5°.

Its supplement angle: 112.5°

112.5° = 5 x 22.5°

i hope this is right <3
