In a certain chemical, the ratio of zinc to copper is 3 to 16 . A jar of the chemical contains 416 grams of copper. How many gr

Anna71 [15]

Answer:

the number of grams of zinc contain is 78

Step-by-step explanation:

The computation of the number of grams of zinc contain is shown below:

Given that the ratio of zinc to copper is 3:16

And, the jar of the chemical has 416 grams copper

So, the number of zinc grams would be

here we assume the zinc grams be x

Now the equation would be

3 ÷ 16 = x ÷ 416

Now applied the cross multiplication

16x = 416 × 3

x = (416 × 3) ÷ 16

= 78

Therefore the number of grams of zinc contain is 78

I need help with letter C, find the area

ElenaW [278]

Answer:

x = 38

Step-by-step explanation:

Here, we can use the area formula A = 0.5(Bh) to solve for x.

In this case, A = 399, B = x, and h = 21

$399 = \frac{21}{2} x\\x = \frac{2*399}{21} \\x = 38$

A triangle is such that the largest angle is three times the smallest angle. Find the measure of each angle

sammy [17]

Let x represent the smallest angle. Then the largest is 3x, and the remaining angle is 180-4x. The problem statement tells us
.. 3x > 180 -4x > x
Adding 4x gives us
.. 7x > 180 > 5x
or
.. 36 > x > 180/7 = 25 5/7

The angles, smallest to largest, are
.. x, 4(45 -x), 3x
where 25 5/7 < x < 36

The angles could be, for example, any of ...
.. 26°, 76°, 78°
.. 30°, 60°, 90°
.. 32°, 52°, 96°
.. 35°, 40°, 105°
and an infinite number of other possibilities.

5. The function h(t) = 1 + 4t - 1.86t? models the height of a rock thrown upward on the planet Mars, where h(t) is height in met

Naily [24]

The maximum height the rock reaches 3.15 feet and the rock will be above the surface for 2.6 seconds

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

From the graph of the function h(t) = 1 + 4t - 1.86t²:

The maximum height the rock reaches 3.15 feet.

Time spent on air = 2.38 - (-0) = 2.38 seconds

The maximum height the rock reaches 3.15 feet and the rock will be above the surface for 2.6 seconds

A spinner has two equal sections, one green and one orange. The spinner is spun three times, resulting in the sample space S = {

Lera25 [3.4K]

The probabilities are as follows

$\rm P(X =0) = \dfrac{1}{8} ,\ P(X =1) = \dfrac{3}{8}, \ P(X =2) = \dfrac{3}{8} , \ P(X =3) = \dfrac{1}{8}$

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A spinner has two equal sections one green and one orange.

The spinner is spun three times, resulting in the sample space (S) will be

S = {GGG, GGO, GOG, OGG, GOO, OGO, OOG, OOO}.

If the random variable X represents the number of times orange.

X = 0, 1, 2, 3

For X = 0, then the probability of not getting orange will be

$\rm P(X = 0) = \dfrac{1}{8}$
