Joseph's uncle wants to put shingles on the outside walls and solar panel the roof of his barn shown at the right. It costs $2.50 for each square meter of shingles, while solar panals cost $4.00 per square meter. How much will this project cost?

Answer:

The two numbers are 18 and 42

Step-by-step explanation:

let the two numbers = x  and y

Their sum:    x + y = 60 ------ (1)

Also, dividing the larger by the smaller (partition = 2 and remainder = 6).

Let the larger number = y

[tex]\frac{y}{x} = 2\frac{6}{x} \\\\\frac{y}{x} = \frac{2x +6}{x} \\\\y = 2x + 6\ \ ----(2)[/tex]

Substitute the value of y into equation (1)

x + (2x + 6) = 60

x + 2x + 6 = 60

3x  +  6 = 60

3x = 60  - 6

3x = 54

x = 54 / 3

x = 18

y = 2x + 6

y = 2(18) + 6

y = 36 + 6

y = 42

The two numbers are 18 and 42

Step-by-step explanation:

Answer:

1/4 ; 3/8

Step-by-step explanation:

Probability of landing on 2 :

Required outcome = Number of 2's on spinner = 2

Total possible outcomes = Number of congruent spaces on spinner = 8

P(landing on a 2) = 2 / 8 = 1/4

Probability of landing on 1 :

Required outcome = Number of 1's on spinner = 3

Total possible outcomes = Number of congruent spaces on spinner = 8

P(landing on a 1) = 3 / 8

Landing in each section of the spinner is equally likely to occur as the spinner are divided into congruent spaces. However, landing on the labels of the spinner isn't equally likely as each label take up uneven number of congruent spaces on the spinner.

Answer:

your y is 6.7

Step-by-step explanation:

Answer:

x = -5

Step-by-step explanation:

Multiply each x and 3 by -4, obtaining

-4x - 12 = 8

Now solve for x by combining the constants:

-4x = 20, or

x = -5

Answer: x=-5

Step-by-step explanation: distribute the -4 first to both x and 3

-4x-12 = 8 then add 12 to both sides to isolate x

-4x= 20

divide by -4 and you get  x= -5

check it

-4(-5+3)

-4(-5)= 20 (a negative times a negative makes a positive)

then -4(3)= -12

20-12= 8

it checks out, hope this helps ^_^

Answer:

The answer should be 5 logx + 2 log y

Answer:

[tex] \frac{ - 4}{3} [/tex]

p= -4/3

Answer:

-4/3

Step-by-step explanation:

17+6p = 9

6p = 9-17

6p = -8

p = -8/6

p= -4/3

nope, this answer is 0.15

Answer:

Step-by-step explanation:

Surface area of the facing side and its opposite side =  4* height = 4 * 2

= 8 m^2

Total surface area = 2 * 8 + 2 * 4 *4 + 2 * 4 * 2.5.

= 16 + 32 + 20

= 68 m^2.

Answer:

area of square = 10 x 10 = 100 cm²

area of circle = πr² = (3.14)(5²) = 78.5 cm²

area of shaded portion = 100 - 78.5 = 21.5 cm²

Answer:

The area is [tex]21.5 cm^2[/tex](if no need to round)

The area is [tex]22 cm^2[/tex](if need to round to nearest whole number)

Step-by-step explanation:

10 x 10 = 100

5 x 5 x π = 25 π

25 x 3.14 = 78.5

100 - 78.5 = 21.5

digits of pi:3.14...

Answer:

a) 1/10, 7/24, 1/2, 13/20

Answer:

Angle 0 is 6.28/3. or 2.093.

Step-by-step explanation:

Pie is an irrational number, so it will be repeating forever. A simple way to get pie is just 3.14. 3.14 times 2 is 6.28. Divide 6.28 by 3 to get 2.093 repeating, but simplified is 2.093.

Answer:

k = 112

Step-by-step explanation:

k/4 - 5 = 23

Add 5 to both sides

k/4 = 28

multiply both sides by 4

k = 112

Answer:

8a - 7

Step-by-step explanation:

First, subtract 12a from 20a

20a - 12a

= 8a

Now, subtract -3 from -10.

Subtracting a negative number is the same as adding a positive number, so add 3 to -10.

-10 + 3

= -7

Put together 8a and -7

8a - 7

So, the simplified expression is 8a - 7

Step-by-step explanation:

[tex]5 \times {10}^{4} \times 9.46\times {10}^{12} = {4.73} \times {10}^{17} [/tex]

Answer:

B. 4.73 × 10¹⁷

Step-by-step explanation:

(5 × 10⁴)(9.46 × 10¹²)

47.3 × 10⁴ ⁺ ¹²

47.3 × 10¹⁶

That is not an option, so we have to divide 47.3 by 10 or increase the exponent.

47.3 × 10¹⁶ ⁺ ¹

4.73 × 10¹⁷

Answer:

c(x) = 5^(x-3) + 2

Step-by-step explanation:

shifting up affects the y axis value

shifting sideways affects the x axis value

when we shift up, we gain value and it is positive, if we shift sideways; to the left, we are losing value and we have to subtract from the x value

So we have our equation as;

c(x) = 5^(x-3) + 2
