Answer 1

Answer:

D = 50

B = 100

C = 100

A = 42

? = 138 degrees

Note: 180 - 130 = 50

180- (30+50) = 100

180-(38+50) = 42

180-42 = 138

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beans of 5 to 2. If he wants to use a total of 126 cans, how many cans of green beans should he use?
please help me lol

Answers

Answer:

90 pumpkin and 36 green beans

Step-by-step explanation:

Because there is a total of 7 parts (5+2) and I divided 126 by 7 and then put five of the 18ns (the quotient of 126 and 7) for pumpkins (so... multiply 18 by 5) then the other to times 18 is 36. And if you add them together, they equal 126.

Answer:

9 cans

Step-by-step explanation:

126/7=18

18/2=9

so 9 is the answer

Answer:

I think the ratio is 3:2 :)

24:16=12/8=6/4=3/2. The answer would be 3:2 bc you divide both sides by 8 or, like I did, divide it by 2 three times.

Answer:

Step-by-step explanation:

No real solutions exist. Subtract 8 on both sides to get:

[tex]x^2=-20[/tex]

You cannot take the square root of a negative number without involving imaginary numbers.

Answer and Explanation

__________________________________________________________

-10

__________________________________________________________

The answer is -10 because...

You need to multiply 2 by "x," and to find out what "x" is, we need to add...

[tex]2+-12[/tex]

__________________________________________________________

And if we add  [tex]2[/tex] by [tex]-12[/tex], we get [tex]-10[/tex], which is our answer.

__________________________________________________________

and now, if we add [tex]-20[/tex] by  [tex]8[/tex], we get [tex]-12[/tex], which is what the equation equals, and this is how we know it is correct.

You have 24 coins valued at $3.00. Some of the coins are dimes and some are quarters. Find the number of each coin that you have.

Answers

Answer:

10 Quarters and 5 dimes

Step-by-step explanation:

10 Quarters = $2.50

5 dime = $0.50

Answer:

20 dimes and 4 quarters

Step-by-step explanation:

So, a dime is 10 cents and a quarter is 25

So, let's say you have x dimes and y quarters

X+Y=24 (total amount of coins)

Also,

10x+25y= 300 (cents)

I just put the 3 dollars into cents

Now, you have a system of equations and we should solve it:

X+y=24 ----x=24-y

10x+25y=300

So substitute x in the 2nd equation

10(24-y)+25y=300

240-10y+25y=300

240+15y=300

15y=60

y=4

Now that you know the amount of quarters, you can just say that you will have 20 dimes since 24-4=20

So, 4 quarters and 20 dimes

Check:

20 dimes=2 dollars

4 quarters= 1 dollar

correct

Step-by-step explanation:

5.7^2+3.2^2=42.73

Sqrt of 42.73=6.5

○=> Correct option :[tex]\color{plum}\tt\bold{(A) \: 6.5 cm}[/tex]○=> Steps to derive correct option :

Given :

Length of leg in a triangle = 3.2 cm

Length of leg of another triangle = 5.7 cm

We know that :

[tex]\color{hotpink}\tt {hypotenuse}^{2} \color{plum} = {base}^{2} + {height}^{2} [/tex]

Which means :

[tex] = \tt {3.2}^{2} + {5.7}^{2} = {h}^{2} [/tex]

[tex] =\tt 42.73 = {h}^{2} [/tex]

[tex] =\tt \sqrt{42.73} = h[/tex]

[tex]\hookrightarrow\color{plum} \tt6.5 \: cm= hypotenuse[/tex]

Thus, the hypotenuse of this triangle = 6.5 cm

Therefore, the correct option is (A) 6.5 cm

Two supplementary angles differ by 34. Find the angles.​

Answers

Answer:

x=107,y=73 is ur answer

Step-by-step explanation:

let two angles be x & y

x-y=34(given)

x=34+y................1

x+y=180(supplementary)

putting the value of x

34+y+y=180

2y=180-34

y=146/2=73

:.y=73

putting the value of y in equation 1

x=34+73=107

:.x=107

Answer:

73° and 107°

Step-by-step explanation:

Mark one of the angles as x

then the other angle is (x + 34)

Two angles are called supplementary when their measures add up to 180 degrees.

So the sum of those angles is always 180°

x + (x + 34) = 180

2x + 34 = 180

2x = 180 - 34

2x = 146

// divide both sides by 2

x = 73°

Now find the other angle

x + 34 = 73 + 34 = 107°

Step-by-step explanation:

1=700

x=1735

1735=700x

1735/700

x=2.47

Answer:

Step-by-step explanation:

This is an exponential equation of the form, A=ar^t, where a is the initial amount and r is the common ratio or rate of growth and t is time. In this case.

A=700(1.12)^t and we want to find when A=1735

1735=700(1.12)^t

1735/700=1.12^t

ln(1735/700)=t(ln(1.12))

t=(ln(1735/700))/(ln(1.12))

t=8 hours
