Answers

Answer:

1. 1/18

2.1/18

Step-by-step explanation:

In order to multiply fractions, you just multiply it straight out. Numerator to numerator, denominator to denominator.

1*1=1

6*3=18

So, the answer is 1/18.

To divide fractions, you flip the second number. If the number is 3, you flip the 3 to the denominator to make 1/3. Then, you multiply using the rule above.

Which equation would best help solve the following problem? The height of a triangle is 5 m less than its base. The area of the triangle is 42 m² What is the length of the base?​

Answers

Answer:

[tex]\boxed{\displaystyle 42=\frac{1}{2}x(x-5)}[/tex]

The second choice is correct

Step-by-step explanation:

Area of a Triangle

Given a triangle of base B and height H, the area is calculated by the formula:

[tex]\displaystyle A=\frac{1}{2}BH[/tex]

Let's call x=base of a triangle

Since the height of the triangle is 5 m less than the base:

x - 5 = height of the triangle.

Thus, the area is

[tex]\displaystyle A=\frac{1}{2}x(x-5)[/tex]

The value of the area is given as A=42 square meters, thus:

[tex]\boxed{\displaystyle 42=\frac{1}{2}x(x-5)}[/tex]

The second choice is correct

Given that ΔABC ∼ΔDEF, m∠A = 108 degrees and m∠E = 40 degrees. Find m∠F. Type ONLY the number of degrees.

Answers

Answer:

∠F = 32°

Step-by-step explanation:

ΔABC & ΔDEF are similar triangles. So, corresponding angles of both triangles are congruent

∠D = ∠A = 108

∠B = ∠E = 40

∠C = ∠F

In ΔDEF,

∠D +∠E + ∠F = 180        {Angle sum property of triangle}

108 + 40 + ∠F = 180

        148 +∠F = 180

                ∠F = 180 - 148

               ∠F = 32°

There are 19 oak trees in a park. Workers will plant more oak trees today. When the workers are finished there will be 56 oak trees in the park. How many oak trees did they plant today?

Answers

Given:

There are 19 oak trees in a park.

There will be 56 oak trees in the park the plantation.

To find:

How many oak trees did they plant today?

Solution:

We have,

Initial number of oak trees = 19

Number of trees after plantation = 56

Now, the number of oak trees they plant today is

New trees = Number of trees after plantation - Initial number of oak trees

                 = 56 - 19

                  = 37

Therefore, they did plant 37 oak trees today.

Suppose that 2000 is invented at a rate of 3.5%, compounded semiannually. Assuming that no withdrawals are made, find the total amount after 4 years. Do not round any interminate computations, And round your answer to the nearest cent.

Answers

Answer:

$2,297.76

Step-by-step explanation:

Present value: P = 2000

Future value: F

Annual interest rate: r = 3.5% = 0.035

Time: t = 4 years

Number of compounding periods per year: n = 2

[tex] F = P(1 + \dfrac{r}{n})^{nt} [/tex]

[tex] F = 2000(1 + \dfrac{0.035}{2})^{2 \times 4} [/tex]

[tex] F = 2000(1 + 0.0175)^{8} [/tex]

[tex] F = 2000(1.0175)^{8} [/tex]

[tex] F = 2000(1.148881783) [/tex]

[tex] F = 2297.76 [/tex]

Write an equivalent expression by distributing the "-−" sign outside the parentheses:
-(-1.5q+5r)+2

Answers

Answer:

1.5q - 5r = 2

Step-by-step explanation:

All you need to do here is negate each term inside the brackets, which allows you to get rid of the minus sign and the brackets.

-(-1.5q + 5r) = 2

is exactly the same as saying:

-1 × (-1.5q + 5r) = 2

And if we multiply each term in the brackets by negative one, we get:

(1.5q - 5r) = 2

And now the brackets can go, leaving you with:

1.5q - 5r = 2

isabels class has collected 90 cans in a food drive they plan to sort the cans into n bags, with an equal number of cans in each bag. write an expression to show how many cans there will be in each bag.​

Answers

Answer:

cn=90, so long as c and n are whole numbers

Step-by-step explanation:

There are two variables in this equation you have here. One, n the number of bags, has already been given to you, because there can be any number of bags. The other, weĺl call it c, is the number of cans in each bag. Because there could be any number of bags, and the number of cans needed in each one is also a variable, you are left with more than one option. Any solution will work so long as the number of cans, c, per bag, n, is equal to the total, 90. There could be 9 cans in 10 bags, or 10 cans in 9 bags, or 15 cans in 6 bags or vice versa. The only way to define it for one answer is to have a set number of bags or cans per bag. Hope this helps!

All my college friends were going, and we decided to dress for the theme, complete with headbands, leg warmers, blue eyeshadow, and teased hair. The night of the party, everyone looked great and we all had a good time.Then I decided to show off. About ten minutes before the party ended, I started trying moves I learned long ago when I dreamed of being an Olympic figure skater. I actually had never been good enough on the ice to get anywhere near the Olympics, but I loved skating and was pretty decent at one point. There I was at the party, spinning, twirling, and skating backward. Then I decided to bring my friend Heidi in on the fun, so I grabbed her hands and pulled her along with me as I skated backward. I was smart enough to be looking behind me to make sure I wouldnt bump into anyone, but I was not smart enough to pay attention to my balance, which I lost.I fell down onto the newly buffed rink floor. Before I knew what was happening, Heidi tripped and fell on top of me, and I heard a crack. I remember feeling the wind get knocked out of me, and then a rush of faces looking down asking if I was okay. My friend Kathleen, who was studying to be a nurse, asked questions to make sure I wasnt seriously injured, and another friend called an ambulance. Since I was not yet feeling any pain, the sheer embarrassment of the moment was my main focus.In the hospital I learned that I had broken a rib and fractured my collarbone. Kathleen had come with and assured me that I was lucky: it could have been much worse. Looking back, I have to laugh at the reaction we got from the hospital staff. Every time a new doctor or nurse walked into my room, we felt the need to explain our getups. The explanation was generally met with blank stares from people who had much more pressing concerns than what the girl in Room 3 was wearing.I went home with strict instructions to move as little as possible for the next few weeks. Lucky for me, I was on summer break so I didnt have to worry about school. Id been planning to stay in my off-campus apartment and work that summer. Instead, I took a leave of absence from my job, formed a stack of books Id been meaning to read for ages, and settled in for what would surely be some of the most boring weeks of my life. The next day, Heidi called and apologized profusely for falling on me. I thanked her but pointed out that it had been my fault that I ended up getting hurt.Even so, we all feel terrible that you ended up in the hospital at the end of a great party, Heidi said. Listen, I called a bunch of people who were there and asked if they wanted to volunteer for a meal drop-off schedule. I have your breakfast, lunch, and dinner covered for the next three weeks. I needed a moment to process what Heidi was telling me. Next to my stack of books was a stack of menus from which Id planned to order all of my food for the next few weeks. The thought of an all-fast food diet had made me a little nauseous, but I knew I wouldnt be able to cook. Now my friends were coming to my rescue.Starting the next morning, in addition to bringing amazing home-cooked meals, as well as some great take-out, my friends took turns visiting me so I didnt get lonely. Those weeks ended up flying by. Before I knew it I was up and about again.Eventually, my friends let me in on what a good laugh they had the night of the party once they knew I was going to be all right, of course. As soon as my rib and collarbone healed I had a pretty good laugh about it, too. I didnt mind that they had laughed. I decided that any group of friends willing to cook for me during summer break was allowed to laugh at me.Which excerpt from the story supports the inference that the narrator was not planning to ask for any help during her recovery?I thanked her but pointed out that it had been my fault that I ended up getting hurt.Next to my stack of books was a stack of menus from which Id planned to order all of my food for the next few weeks.I took a leave of absence from my job, formed a stack of books Id been meaning to read for ages, and settled in for what would surely be some of the most boring weeks of my life.Since I was not yet feeling any pain, the sheer embarrassment of the moment was my main focus.
