Answer:

117

Step-by-step explanation:

Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)

a²+b²=c²

A= 75

B= 90

C is always the hypotenuse.

75²+90²= c²

5,625+8,100= 13,725

√13,725= 117.15374513859981591194584103639

To the nearest whole number: 117

To the nearest tenth: 117.2

Hope this helps!

If it takes 4 men 6hours to repair a road, how long will it take 7 men to do the job if they work at the same rate.
Crank
Tricky question. This isn't a ratio question even though it seems like one.

First divide 7 by 4.
7 \div 4 = 1.75

With more men, the hours taken to repair a road will be even shorter.

So next divide 6 by 1.75.
6 \div 1.75 = 3.43

Answer : It'll take 3.43 hours to do the job if they work at the same rate.

Hope this helps. - M

Solve: 1 5 x = -10 A) -50 B) -20 C) -2 D) 2
Inessa [10]

Answer:

In order to find x, you will have to use the operation of equality to isolate the x.


15x=-10

<em>Now, use the division property of equality and divide by 15 on both sides. This will cancel out the 15 on the left side of the equation and isolate the x completely.</em>

-10/15=\frac{-2}{3}

<em>Thus, this is your answer:</em>

\boxed{x=-\frac{2}{3} }

3. Try It #3 Write the point-slope form of an equation of a line with a slope of -2 that passes through the point (-2,2). Then r
vova2212 [387]

Answer:

Point-slope form of equation given as $y-2=-2(x+2)$.

Slope-intercept form of equation is given as $y=-2 x-2$.

Step-by-step explanation:

In the question, it is given that the slope of a line is -2 and it passes from (-2,2).

It is asked to write the point-slope form of the equation and rewrite it as slope-intercept form.

To do so, first find the values which are given in the question and put it in the formula of point-slope form. Simplify the equation to rewrite as slope-intercept form.

Step 1 of 2

Passing point of the line is (-2,2).

Hence, $x_{1}=-2$ and

$$y_{1}=2 \text {. }$$

Also, the slope of the line is -2.

Hence, m=-2

Substitute the above values in point-slope form of equation given by $y-y_{1}=m\left(x-x_{1}\right)$

$$\begin{aligned}&y-y_{1}=m\left(x-x_{1}\right) \\&y-2=-2(x-(-2) \\&y-2=-2(x+2)\end{aligned}$$

Hence, point-slope form of equation given as y-2=-2(x+2).

Step 2 of 2

Solve y-2=-2(x+2) to write it as slope-intercept form given by y=mx+c.

$$\begin{aligned}&y-2=-2(x+2) \\&y-2=-2 x-4 \\&y=-2 x-4+2 \\&y=-2 x-2\end{aligned}$$

Hence, slope-intercept form of equation is given as y=-2x-2.

Answer:

53°

Step-by-step explanation:

x + (2x + 21) = 180

(Corresponding angles &

Supplementary angles)

3x + 21 = 180

3x = 159

x = 53°
