Jason a 4 lengths of rope. The lengths are 3 inches, 15 centimeters, 0.3 meters, and 0.5 feet. About how much rope does Jason ha

AnnZ [28]

Answer: 67.5 cm

Step-by-step explanation:

Jason has 4 lengths of ropes

first is $3\ in.\approx 7.5\ cm$

second is $15\ cm$

Third is $0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}]$

fourth is $0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}]$

the total length of rope is the sum of four lengths

$\Rightarrow 7.5+15+30+15=67.5\ cm$

Describe the characteristics of each set of numbers that make up the set of integers

earnstyle [38]

There are different types of numbers: they could be natural numbers, whole numbers, rationals, real numbers, and integers. Integers are a set of numbers consisting of positive and negative numbers excluding decimals and fractions. The following are its characteristics:

<span>*Negative numbers mean numbers that are below zero. </span>

<span>*Zero is part of the set of integers. </span>

<span>*Number categories overlap with each other. </span>

<span>*When writing a set of integers, they must be inside a bracket ‘{}’ and with ellipses “…”. </span>
<span>
*When adding or subtracting integers, use a number line. </span>

In triangle STU, u2 = s2 + t2.

sineoko [7]

Answer:

(B) The measure of angle SUT is equal to 90 degrees

Step-by-step explanation:

It is given that in In triangle STU, $u^2=s^2+t^2$ .

We can see from the triangle and also the given condition that the triangle will be right triangle as it is satisfying the Pythagoras theorem.

$(Hyp)^2=(Base)^2+(Perpendicular)^2$

that is:

$u^{2}=s^{2}+t^{2}$

where u is the hypotenuse, s is the base and t is the perpendicular.

Thus, the angle SUT should be of 90°.

Thus, The measure of angle SUT is equal to 90 degrees.

Hence, option B is correct.

A worker on a scaffolding 75 ft above the ground needs to lift a 500 lb bucket of cement from the ground to a point 30 ft above

Lemur [1.5K]

Answer:

W = 15900 ft.lb

Step-by-step explanation:

From the given information.

Consider y to be the distance from the ground towards the bucket of the cement.

At height y, suppose the bucket is lifted by Δy.

Then, the workdone can be = 500Δy + 0.5(75 - y) Δy

where;

The bucket of the cement = 500Δy

The remaining of the rope = 0.5(75 - y) Δy

However; the workdone (W) can be calculated as:

$W = \int^{30}_{0} \ 500 \ dy + \int^{30}_{0} \ 0.5 (75-y ) \ dy$

$W = 500 \times 30 + 0.5 \bigg(75 \times 30 - \dfrac{1}{2} \times 30^2 \bigg )$

W = 15000 + 0.5 ( 2250 - 450)

W = 15000 + 900

W = 15900 ft.lb
