Answer:

3 5/7

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

10x + 5y = 70

21x - 28y = 70

21x - 28y = 10x + 5y

11x = 33y

x = 3y

7y = 14

y = 2

x = 6

Answer:

Step-by-step explanation:

The sum of interior angles of a triangle = 180°

Therefore,  ∠ABC + ∠BAC + ∠BCA = 180°

                          ⇒ 42 + 64 + ∠BCA = 180°

                                           ⇒ ∠BCA = 180 - 42 - 64

Answer:

2) A, 3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total? 4) A, C, E. 5) 4

Step-by-step explanation:

2) Elena already walked 12 miles, she then walks another 1/4 of those 12 miles. The answer is A.

3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total?

4) to find the answers figure out how much they multiply one number by and multiply the other number by that amount. For example, the ratio 2:5 can be the same as 4:10 because you are multiplying the original ratio by 2 to get the new ratio.

5) The diameter of a circle is the length of one side to another. to find the length of the outer edge you need to find the circumference. To find the circumference of a circle you must use [tex]\pi[/tex]*Diameter. To find the answer we must use 180/[tex]\pi[/tex]D. Since pi can not be defined we will use 3.14 as a rough estimation. 3.14*12=37.68. 180/37.68=4.777070064. Since it doesn't make much sense to do .8 of a invitation then we must round down. The answer is 4.

Step-by-step explanation:

25 questions, 2 points each.

that means there were 25×2 = 50 points in total.

Gideon got 42 out of the 50.

100% = 50

1% = 100%/100 = 50/100 = 0.5

42 is how many % ? as many as 1% (0.5) fits into 42.

so,

42/0.5 = 42×2 = 84%

he scored 84%.

Answer: 26 + c = 100

Step-by-step explanation: To find what c equals, we must flip the solution around and subtract it. When we take 100 - 26, we get 74. Therefore, c = 74. I hope this helped! :)

Answer:

A 5kW solar system is made up of 20 solar panels, assuming that the panels have 250-watt capacity. The size of each panel will be approximately 1.6 m x 1 m, so at least 32 m² of roof space is needed to suit the space needs of this system.25 Oct 2021

Answer:

Part A: by finding equation and x value is size.

Take two coordinates: (20, 1/5), (40,2/5)

slope:

[tex]\frac{y2-y1}{x2-x1}[/tex]

[tex]\frac{\frac{2}{5} -\frac{1}{5} }{40-20}[/tex]

[tex]\frac{0.2}{20}[/tex]

[tex]0.01[/tex] ......this is slope, unit rate.

Equation:

y - y1 = m( x - x1 )

y - 1/5 = 0.01(x - 20)

y = 0.01x ........this is the equation

The y determines the size of kilowatts of energy

So y = 5

5 = 0.01x

x = 500 square feet

500 square feet is required to produce 5 kilowatts of energy.

Answer:

b. YZ

Explanation:

Answer:

Step-by-step explanation:Slope m = yB − yA xB − xA Slope m = y B - y A x B - x A. Solution: Slope m = 10 − 2 7 − 3 Slope m = 10 - 2 7 - 3. = 8 4 = 8 4. m = 2.

Answer:

its 0.9 which is 90 I Literally divided it

Step-by-step explanation:

£6.30 divided by 7 is equal to 90 pence.

In mathematics, the division operation splits left-hand operands into right-hand operands. The division's primary goal is to create equal groups or to ascertain how many individuals are in each category following a fair distribution.

For example 4/2 = 2

To convert £6.30 to pence, we multiply it by 100 because there are 100 pence in 1 pound.

£6.30 x 100 = 630 pence

Now, to calculate 630 pence divided by 7:

630 pence / 7 = 90 pence

Therefore, £6.30 divided by 7 is equal to 90 pence.

Answer:

x=(+10,-4)

Step-by-step explanation:

find two number if you multiple it becomes (-40) and if you add it becomes (-6)

Answer:

f(-6) = -21

Step-by-step explanation:

Substitute x = -6 into f(x):

f(-6) = 3(-6) + (-6 ÷ 2)

       = -18 - 3

       = -21

Given :

[tex]f(x) = 3x + \frac{x}{2} [/tex]

Substituting -6 in x,

[tex]f( - 6) = 3 \times ( - 6) + \frac{ - 6}{2} [/tex]

[tex] = > f( - 6) = (- 18) + (- 3)[/tex]

[tex] = > f( - 6) = - (18 + 3)[/tex]

[tex] = > f( - 6) = - 21[/tex]

So, value of

[tex]f( - 6) = - 21[/tex]

Answer:

x=5

Step-by-step explanation:

−8(x−1)=−32

(−8)(x)+(−8)(−1)=−32

−8x+8=−32

Step 2: Subtract 8 from both sides.

−8x+8−8=−32−8

−8x=−40

Step 3: Divide both sides by -8.

−8x    -40

−8   =−8

x=5

Answer:

Step-by-step explanation:

m∠D = 90° - 51° = 39°

sin E = [tex]\frac{DE}{DF}[/tex] ⇒ DE = DF × sin E

DE = 18 sin51° ≈ 14.0 ft.

cos E = [tex]\frac{EF}{DF}[/tex] ⇒ EF = DF × cos E

EF = 18 × cos51° ≈ 11.3 ft.

Answer

200 - ( x * 25 ) = y

Step-by-step explanation:

200 is the original amount of gallons of water the reservoir contained before it started to be drained.

The ' - ' negative symbol is there because the reservoir is losing gallons of water when it is being drained.

x represents the amount of hours it is being drained for.

25 is the amount of gallons the reservoir is losing per hour assuming it is being drained.

The ' * ' multiplication sign is there because ' x ' represents the amount of hours the reservoir could be being drained for, and 25 represents how many gallons of water the reservoir loses for every 1 hour it is being drained.

y is the number of gallons left in the reservoir after being drained for 'x' amount of hours.
