Answer:

48 degrees

Step-by-step explanation:

1) Solve for x

Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:

[tex]A+B=90\\(2x+20)+(3x)=90[/tex]

Open up the parentheses

[tex]2x+20+3x=90\\5x+20=90[/tex]

Subtract 20 from both sides

[tex]5x+20-20=90-20\\5x=70[/tex]

Divide both sides by 5

[tex]\frac{5x}{5} =\frac{70}{5} \\x=14[/tex]

Therefore, x is equal to 14.

2) Determine angle A

[tex]A=2x+20[/tex]

Substitute x with 14

[tex]A=2(14)+20\\A=28+20\\A=48[/tex]

Therefore, the measure of angle A in degrees is 48 degrees.

Answer:

ok so..to find out the amount it cost per square foot you have to multiply 9*12=108 ft

108ft=$480

$480/108=4.44~~~~~it's continuous

so then multiply 21*28=588

588*4.44~~~~=2613.33~~~~its continuous too.

Answer:

Paul Revere’s famous ride on April 18th, 1775 is the subject of this famous Longfellow poem. It is told from the perspective of a landlord who is hoping to entertain and inform his “children”. ‘Paul Revere’s Ride’ was published in Atlantic Monthly magazine in 1861 around the beginning of the Civil War. Longfellow wrote this piece with the intent of inspiring Northerners.

One of the less discussed elements of this poem is its function as an anti-slavery statement. There are several allusions in this poem, such as to a burial ground for enslaved people and the use of the name “Somerset” at the beginning of the poem. The latter is connected to a landmark case that outlawed slavery in Britain in 1772.

Answer:

  A.  (0, 5), (5, 1)

Step-by-step explanation:

The midpoints of the diagonals of a parallelogram are the same point. This means the sum of the opposite vertex coordinates will be the same.

For the given diagonal, the sum of end point coordinates is ...

  (-2, -3) + (7, 7) = (-2+7, -3+7) = (5, 4)

__

This means we're looking for a pair of coordinates whose sum is (5, 4).

  A: (0, 5) +(5, -1) = (0+5, 5-1) = (5, 4) . . . . . . the points we want

  B: (0, 4) +(4, -1) = (4, 3) . . . not it

  C: (-1, 5) +(5, 0) = (4, 5) . . . not it

  D: (-1, 4) +(4, 0) = (3, 4) . . . not it

__

In the attached, the blue line segment is the only one that passes through the midpoint of the given diagonal. It has end point coordinates

  (0, 5) and (5, -1) . . . matching choice A

Answer:

Step-by-step explanation:

probability of getting 1 cream filled and 1 jelly donut = (Total number of cream filled donut / total number of donuts) x (Total number of jelly filled donut / total number of donuts)

total number of donuts = 3 + 3 + 4 = 10

(3/10) x (4/10) = 12/100

to express in is simplest term, divide through by 4 = 3/25

Answer:

14.99 hours

Step-by-step explanation:

The formula for half-life is given as,

R/R' = 2ᵃ/ᵇ...................... Equation 1

Where R= Original mass of sodium-24, R' = mass of Sodium-24 after disintegration, a = Total time taken for sodium-24 to disintegrate, b = half-life of sodiun-24.

Given: R = 1 kg, R' = 0.0156 kg, a = 90 hours

Substitute into equation 1 and solve for b

1/(0.0156) = 2⁹⁰/ᵇ

Taking the log of both side

log[1/(0.0156)] = log(2⁹⁰/ᵇ)

log[1/(0.0156)] = 90/b(log2)

90/b = log[1/(0.0156)]/log2

90/b = 6.0023

b = 90/6.0023

b =  14.99 hours

b = 14.99 hours.

Hence the half-life of Sodium-24 is 14.99 hours

Answer:

c

Step-by-step explanation:

The values of the variables x and y in table C is satisfying the equation y = 0.5x + 14.

The linear equation is defined as the equation having a degree of one or the power of the variable will be one.

The table data is,

x           y

0          14

5          16.5

10        19

15        21.5

20       24

The table data is satisfying the equation y = 0.5x + 14.

At ( 0,14)

y = 0.5x + 14.

14 = 0 + 14

14 = 14

At ( 5,16.5)

16.5 = (0.5 x 5) + 14

16.5 = 2.5 + 14

16.5 = 16.5

At (10.19)

19 = (0.5 x 10 ) + 14

19 = 5 + 14

19 = 19

Therefore, the values of the variables x and y in table C is satisfying the equation y = 0.5x + 14.

Step-by-step explanation:

The amplitude is 1.  

This graph does not go through the origin, but has been translated up by 1 unit.  If you draw a horizontal line through y = 1 you will see that the maximum distance the curve reaches above y = 1 is 1, which is the amplitude.
