the metal bar/random line is almost the same size as the other two sides of the triangle. if one side is 32ft, then the opposite side is 32ft also. the bottom is 100ft, so we could eliminate C. because it couldnt be that number. now the bottom triangle, one side is 40ft so the other side has to be 40ft as well. its asking about the metal bar.

its either:

A. 53.2ft or

B. 44.4

because the line is almost the same size as 32ft. its almost a equallateral triangle. i would go with A. though because if you imagine the line at the bottom of the line (100ft.) the line would go over half of it (and 53.2 is over half of 100) so i would say

A.53.2

if this didnt help let me know. and i will delete this (if i can-)

Answer:so it would be between 14/20

Step-by-step explanation:

Answer:

Step-by-step explanation:

Well first you should rearrange the equation to make it easier to graph. 8x-4y=16.

8x - 4y = 16.

8x +4y = 16 + 4y

8x -16 = 4y

Divide both sides by 4 to get y by itself.

2x - 4 = y

The y-intercept is -8 and the slope is 2x so the graph would look something like this.

Answer:

Aluminum

Step-by-step explanation:

To find the unit rate being used for the substance, we need to divide the grams by the cubic measurement. ([tex]g[/tex]/[tex]cm^{3}[/tex]).

108 grams divided by 40 is 2.7, which is the density of Aluminum, therefore making Aluminum the answer.

Whitch of the following number is between 2/5 and 7/8

Answers

Answer:

The correct answer is B.

Lets go through explaination:

According to the question, the answer should be between 2/5 and 7/8

If we changed the fraction into decimal, we will get 2/5 as 0.4 and 7/8 as 0.875

So now, we have to get the numbers in between 0.4 and 0.875

Changing all the fraction in the form of decimal:

15/16 = 0.93753/4 = 0.753/8 = 0.3751/3 = 0.33333333333......

In the above answers, only no. B is between 2/5 and 7/8.

So, B is the correct answer.

If f(x)=6x-15 and f(a)=30, what is the value of a?
Please help

Answers

Answer:

[tex]a=7.5[/tex]

Step-by-step explanation:

Given the function [tex]f(x)=6x-15[/tex] and the output [tex]30[/tex] when [tex]x=a[/tex], we can write the equation:

[tex]6a-15=30[/tex]

[tex]6a=45[/tex]

[tex]a=7.5[/tex]

We can insert the value of [tex]a[/tex] into the function to verify the output equals [tex]30[/tex]:

[tex]f(a) = 6a-15[/tex]

[tex]= 6(7.5)-15[/tex]

[tex]=30[/tex]

∴ We have verified that [tex]a=7.5[/tex]

What is geometric transformation?

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a point 'p' which is a fixed point.

Triangle ABC is rotated about the 'p' point such that the new location of A, B, and C becomes A', B', and C'.

The new triangle formed is triangle A'B'C'.

From the figure, we can clearly see that the angle APA' is a right-angle triangle.

m∠APA' = 90°

Thus, the value of angle APA' is 90°.

The owner where your work explains that you're paid $8/hour and receives a $25 bonus each month for being the manager. If the owner hands you a check for $250, How many hours did you work this month? Write an equation and solve.

Answers

Answer:

28.125 hours

Step-by-step explanation:

Amount of money paid per hour = $8

Bonus of being a manager = $25

Total amount of money paid = $250

To find:

Number of hours worked for this month?

Solution:

Let the number of hours worked = [tex]h[/tex] hours

Amount of money paid for [tex]h[/tex] hours = $8[tex]h[/tex]

As per question statement:

Bonus + Amount of money paid for [tex]h[/tex] hours = $250

[tex]25 + 8h = 250\\\Rightarrow 8h = 250 -25\\\Rightarrow 8h = 225\\\Rightarrow h =\dfrac{225}{8}\\\Rightarrow \bold{h = 28.125\ hours}[/tex]

Therefore, the answer is:

Number of hours worked = 28.125 hours

Please help! 426 1/5 - 275 ½= ?

Answers

Answer:

150.7

Step-by-step explanation:

To solve this, we first turn both the fractions into decimals :

[tex]\frac{1}{5} = 0.2\\[/tex] (add this to 426 to get 426.2)

[tex]\frac{1}{2} = 0.5[/tex] (add this to 275 to get 275.5)

Then, just solve the equation :

426.2 - 275.5 = 150.7

In 2005, the Centers for Disease Control proposed deliberately combining a deadly bird flu virus with a very contagious human flu virus to understand whether and how it might cause a worldwide outbreak, or "pandemic. Scientists said the lab experiments would help them understand what might already be happening naturally. . . .But other people thought such research was a terrible idea. What if these viruses escaped the lab by mistake? What if a government or terrorist organization wanted to use the viruses against their enemies?In 2013, two research groups outside the United States went ahead and conducted their own experiments. One group, led by Ron Fouchier of Erasmus University in the Netherlands, showed that the highly lethal mixed up flu virus could infect and kill ferrets. A few months later, a Chinese group led by Chen Hualan at Chinas Harbin Veterinary Research Institute showed the recombined virus could infect and kill guinea pigs. Both groups ran their studies before a worldwide ban on this type of research was put into place in 2012.One of the main ideas presented in this passage is the controversy over whether or not flu research is safe. What do these paragraphs suggest about the safety of such research?A worldwide ban on dangerous flu research was put into place in 2012, so the threat of people using flu viruses to attack others no longer exists.Since all of the information that could be learned from such research has already been discovered, scientists no longer need to create new flu viruses, and therefore the controversy is over.Although none of the deadly flu viruses made for research have been used by dangerous people, since that possibility still exists, the ban on the research might be important.The research has already resulted in the deaths of animals, so people who once thought creating and researching new flu viruses was important are no longer supporting it. which orbital has the highest energy level 80 + ? + -30 = 0 whats in the middle Explain the path food takes from your plate to becoming waste.
