Answer:

276 unit^2.

Step-by-step explanation:

This area  is the sum of the area of 2 rectangles

= 12 * 13 + 8 * 15

= 156 + 120

= 276.

Step-by-step explanation:

Answer:

x + y =90

Step-by-step explanation:

So to find any angle in a complementary set you would subtract the angle given by 90.

Easy way to remember what complementary means is the C is like the curve of 9 in 90 and in supplementary the S is like half a 8 in 180.  

Answer:

The first number is 138.

Step-by-step explanation:

Let the first number be x.

Then since they are consecutive numbers, the second number will be (x + 1), the third (x + 2), the fourth (x + 3) and the fifth being (x + 4).

We are given that their sum is 700. Therefore:

[tex]x+(x+1)+(x+2)+(x+3)+(x+4)=700[/tex]

Solve for x. Combine like terms:

[tex]5x+10=700[/tex]

Subtract 10 from both sides:

[tex]5x=690[/tex]

Divide both sides by five. Therefore:

[tex]x=138[/tex]

The first number is 138.

Answer:

138

Step-by-step explanation:

(n) + (n+1) + (n+2) + (n+3) + (n+4) = 700

5n + 10 = 700

5n = 690

n = 138

Answer:

a. integer

b. rational

c. irrational

d. rational

e. whole

f. rational

g. integer

h. irrational

i. natural

j. integer

Step-by-step explanation:

natural = 1, 2, 3, 4, ......

whole = 0, 1, 2, 3, 4, ....

integer = -5, -6, 0, 1, 2, 3, 4, ....

rational = can be fractional also 1, 2, 0, -5, -7, 5/3, -7/9

irrational = can't be fractional √2, 8.93845859382, 7.324464213

Answer:

The answer is 40%

Step-by-step explanation:

Answer:

∠ 1 = 94°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

130° is an exterior angle of the triangle, then

∠ 1 + 36° = 130° ( subtract 36° from both sides )

∠ 1 = 94°

Answer:

If they would both work at the same speed they would each take 4 hours to complete the room. So in total they would work 8 hours. But because Carl can finish three hours before Jennifer 3 hours of the eight already got to Jennifer. Then we divide the resting 5 hours by the two and then we have:

Jennifer:

3+2,5=5,5

Carl:

2,5

( if I am right)

Answer:

95°

Step-by-step explanation:

x+49+x+59=180

2x+108=180

2x=180-108

2x=72

x=72/2=36

m L H = x+59=36+59=95°

Answer:

8^(-3) = 0.00195 or 1/512

Step-by-step explanation:

Given:      "the log to the base 8 of 1/512" is 3 is actually false.  The correct version is "the log to the base 8 of 1/512" is -3 (negative 3).  (Log form.)

Please note:   8^(-3) = 0.00195 or 1/512   (This is in exponential form.)

Answer:

[tex] \frac{x + 2}{3x - 1} [/tex]

Step-by-step explanation:

Things you should before solving this question :-

where a and b are any two variables.

SIMPLIFYING THE EXPRESSION

[tex] \frac{ {x}^{2} - 9 }{3 {x}^{2} + 8x - 3} \div \frac{x - 3}{x + 2} \\ [/tex]

using the identity discussed above

[tex] \frac{ (x + 3)(x - 3) }{3 {x}^{2} + 8x - 3} \div \frac{x - 3}{x + 2} [/tex]

simplifying 3x² + 8x - 3

[tex] \frac{ {x}^{2} - 9 }{3 {x}^{2} + 9x -x - 3} \div \frac{x - 3}{x + 2} [/tex]

as 8x can be written as 9x - x

[tex] \frac{ (x - 3)(x + 3) }{3 {x}(x + 3) - 1(x + 3)} \div \frac{x - 3}{x + 2} \\ \frac{ (x - 3)(x + 3) }{(3 {x} - 1)(x + 3) } \div \frac{x - 3}{x + 2} [/tex]

flipping the fraction that follows division sign and inserting multiply in place of divide

[tex] \frac{ (x - 3)(x + 3) }{(3 {x} - 1)(x + 3) } \times \frac{x + 2}{x - 3} [/tex]

canceling (x - 3) and (x + 3) as they're common in both denominator and numerator

[tex] \frac{x + 2}{3x - 1} [/tex]
