PLS HELPP PLSSSSSSSSSSs
Part B
If Marcus’s dad wanted to re-cover the whole tent including the bottom, how much material would he need? Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning.
Answer:
A) How much material does he need to cover the one rectangular side of the tent with the rip? Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning.
Answer: If David’s dad wanted to cover the rectangular side of the tent, he would need to multiply the sides together. Using the formula A = l x w, I can solve for 6 and 9. 9 x 6 = 54, so 54 = 6 x 9.
B) If David’s dad wanted to re-cover the whole tent including the bottom, how much material would he need? Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning.
Answer: If he wanted to re-cover the whole tent, he would need the product of the rectangular side, the triangular side, and the bottom side. Using A = l x w, I can solve for each side of the tent, For the rectangular side you multiply six by nine, then multiply two by the product. 6 x 9 = 54 x 2 = 108. For the triangular side, I need to multiply six times seven, 6 x 7 = 42. For the bottom, I need to multiply seven times nine, 7 x 9 = 63. Finally, I need to add them all up. 108 + 42 + 63 = 213 ft².
C) What is the volume of the tent? Justify your answer using equations/formulas, models, and/or words to explain your mathematical reasoning. (You need to find the area of one of the triangular bases, and then you can take that measurement and multiply it with the height of the entire prism.) V=Bh, where B = area of one of the triangular bases
Answer: I need to find the volume of the tent, so I need to find the formula which is V = B x h. The base is 63, because I needed to find the area of one of the triangular bases, so I multiplied 7 x 9 = 63. The height is 6, so I need to multiply 63 x 6. When I multiply 63 x 6, I get the product of 378, so the volume of the tent is 378 ft³.

Find the value of c that makes the expression a perfect square trinomial. x^2+10x+c A. 20 B. 25 C. 50 D. 100
Answer:
The answer is B.
Step-by-step explanation:
In the options, 25 is perfect square of 5 and 100 is square of 10.
So when 5 + 5, you will get 10 which is the 2nd term of the expression.

Each day that Samantha rides the train to work, she pays $4.00 each way. If Samantha takes the train to work and back 3 times, which amount represents the change in her money?
Answer:
Total ticket expenses = $24
Step-by-step explanation:
Given:
Each way cost = $4
Total ways = 3 x 2 = 6 times
Find:
Total ticket expenses
Computation:
Total ticket expenses = Each way cost x Total ways
Total ticket expenses = 4 x 6
Total ticket expenses = $24
Researcher were testing out a new antibiotic on a certain bacteria. They started with 38,000 bacteria. After one treatment with antibiotics, 33,820 were left. After a second treatment, 30,100 bacteria were left. How many bacteria will be left on day 27
Answer:
1836 bacteria
Step-by-step explanation:
Now the data is a progression; 38,000, 33,820, 30,100 .........
We can find out what type of progression it is, in this case, we can see that it is a geometric progression because;
r= 33,820/38,000 = 30,100/33,820 = 0.89
So, for a geometric progression;
Un = ar^n-1
Where;
a = 38,000
r = 0.89
n = 27 days
Un = ???
Un = 38,000 * (0.89)^27 - 1
Un = 1836 bacteria

In the triangle below, with right angle A, suppose that m is Angle B=(5x+7) and m is Angle C=(4x+29) Find the degree measure of each angle in the triangle. A= 90 B=(5x+7) C=(4x+29)
Given:
Triangle ABC is right angled at A.
[tex]m\angle B=(5x+7)^\circ[/tex]
[tex]m\angle C=(4x+29)^\circ[/tex]
To find:
The degree measure of each angle in the triangle.
Solution:
According to the given information,
[tex]m\angle A=90^\circ[/tex]
[tex]m\angle B=(5x+7)^\circ[/tex]
[tex]m\angle C=(4x+29)^\circ[/tex]
Now,
[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex] (Angle sum property)
[tex]90^\circ+(5x+7)^\circ+(4x+29)^\circ=180^\circ[/tex]
[tex](9x+126)^\circ=180^\circ[/tex]
[tex]9x+126=180[/tex]
[tex]9x=180-126[/tex]
[tex]9x=54[/tex]
Divide both sides by 9.
[tex]x=\dfrac{54}{9}[/tex]
[tex]x=6[/tex]
Now,
[tex]m\angle A=90^\circ[/tex]
[tex]m\angle B=(5(6)+7)^\circ[/tex]
[tex]m\angle B=37^\circ[/tex]
[tex]m\angle C=(4(6)+29)^\circ[/tex]
[tex]m\angle C=53^\circ[/tex]
Therefore, the measures of ∠A, ∠B, ∠C are 90°, 37°, 53° respectively.

C. 1/9
D. 1/12
Answer:
the answer is A
Step-by-step explanation:
I am thinking of a 3 digit number when I divide it by 5 I am left with a remainder of 3 when I divide it by 10 I am left with a remainder of 8 it rounds to 200 to the nearest 100 it had one hundrred whatt is my number
9514 1404 393
Answer:
any of 158, 168, 178, 188, 198
Step-by-step explanation:
If the remainder is 8 when divided by 10, the least-significant digit must be 8. (That will guarantee that division by 5 will give a remainder of 3.)
In order for a number with one hundred to round to 200 when rounded to the nearest 100, the tens digit must be 5 or larger. There are 5 numbers that meet these criteria:
158, 168, 178, 188, 198
