Answer:

72

Step-by-step explanation:

We know that it isn't a 90 degree angle so we do process of elimination, now we have 2 answers, just by looking at it is is probably 72. Hopefully you get it right.

A cylinder has a base radius of 4m and a height of 6m. What is its volume in cubic m, to the nearest tenths place?

Ronch [10]

<h3>Answer:</h3>

301.6 cubic meters

<h3>Step-by-step explanation:</h3>

A cylinder is a shape with straight sides with circular or oval cross-sections. We know that the cylinder in the question must be a circular cylinder due to its radius description.

Volume Formula

A circular cylinder has a volume of $V=\pi r^2h$ . In this equation, V is the volume, r is the radius, and h is the height. The question tells us that r=4m and h=6m. So, we can plug these values into the formula.

Solving for Volume

To solve plug the values into the formula and rewrite the equation.

$V=\pi *4^2*6$

Next, apply the exponents.

$V=\pi *16*6$

Then, multiply the constants.

$V=\pi *96$

Finally, multiply the remaining terms. Remember to use the pi button on the calculator and not an estimation to get a more exact value.

$V=301.6$

Make sure your answer is rounded to the correct digit. This means that the volume must be 301.6 cubic meters.

Answer:

measure of angle p=

94

Step-by-step explanation:

ok 5 sided polygon= 540

so put all of those equal to 540

need to find x first

540=132+(4x-10)+(5x-11)+128+(4x+2)

simplify and combine like terms

x=23

now plug in for angle p

(4(23)+2)

A car drives east along a road at a constant speed of 46 miles per hour. At 4:00 P.M., a truck is 264 miles away, driving west a

sveticcg [70]

Answer:

The speed of the truck is 42 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s -----> the speed in miles per hour

d ----> the distance in miles

t ----> the time in hours

$s=\frac{d}{t}$

$d=s(t)$

step 1

Find out the distance traveled by the car at 7:00 P.M

we have

$s=46\ \frac{mi}{h}$

$t=7:00 P.M-4:00 P.M=3\ h$

$d=s(t)$

substitute the values

$d=46(3)=138\ mi$

step 2

Find out the speed of the truck

we know that

At 7:00 P.M the distance is equal to

$d=264-138=126\ mi$

$t=7:00 P.M-4:00 P.M=3\ h$

substitute

$s=\frac{126}{3}$

$s=42\ \frac{mi}{h}$

Answer:

$y=-\frac{9}{7}x-2$

Step-by-step explanation:

Here, we have to convert the equation to slope-intercept form so we can find the perpendicular slope:

$7x-9y=-5$

$-9y=-5-7x$

$y=-\frac{5}{9}+\frac{7}{9}x$

$y=\frac{7}{9}x-\frac{5}{9}$

Since our slope is $m=\frac{7}{9}$ , then that means the slope perpendicular to it is $m=-\frac{9}{7}$ .

Now we find our new y-intercept so that the line will pass through the point (-7,7):

$y=mx+b$

$y=-\frac{9}{7}+b$

$7=-\frac{9}{7}(-7)+b$

$7=9+b$

$-2=b$

Therefore, the equation of the new line is $y=-\frac{9}{7}x-2$
