Answer:

11

Step-by-step explanation:

The absolute value of any positive number is the number itself, so 11 has 11 as an absolute value. Also, the absolute value of a negative number is its (positive) opposite, so also has 11 as an absolute value.

Answer:

Gross = $712.5

Social security = $44.175

Medicare = $10.33125

Step-by-step explanation:

Given that :

Hourly pay = $15

Hours over 40 = 1.5 * $15 = $22.5

Total hours worked last week = 45

Total pay :

(40 * $15) + (45 - 5)*$22.5

$600 + $112.5

= $712.5

Hence, weekly gross pay = $712.5

Social security tax percent =(6.2%)

0.062 * gross = 0.062 * $712.5 = $44.175

Medicare tax percent = (1.45%)

0.0145 * $712.5 = $10.33125

Answer:

254.34 inches²

Step-by-step explanation:

The formula for area of a circle is: pi x r². The radius is half of the diameter (18) which in this case would be 9. Square it to get: 81. Multiply by pi: 81 x 3.14 = 254.34.

Answer:

12.0 cm

Step-by-step explanation:

✔️First, find the height, BC, of the trapezium using Pythagorean Theorem.

BC² = 10² - (9 -3)²

BC² = 10² - 6²

BC² = 64

BC = √64

BC = 8 cm

✔️Find AC using Pythagorean Theorem:

AC² = AB² + BC²

AC² = 9² + 8²

AC² = 145

AC = √145

AC = 12.0415946 ≈ 12.0 (3 significant figures)

Answer:

The statement that is not true is;

c) m∠ABO = m∠ODC

Step-by-step explanation:

With the assumption that the lengths AO, and OD are equal, we have that in ΔABO and ΔOCD, the following sides are corresponding sides;

Segment AO on ΔABO is a corresponding side to segment OD on ΔOCD

Vertices B and C on ΔABO and ΔOCD are corresponding vertices

Therefore;

Segments AB and OB on ΔABO are corresponding sides to segments OC and OD on ΔOCD respectively

Therefore, ∠ABO on ΔABO is the corresponding angle to ∠OCD on ΔOCD

Given that ΔABO ≅ ΔOCD, we have that ∠ABO ≅ ∠OCD

Therefore;

m∠ABO = m∠OCD by definition of congruency

Answer:

Step-by-step explanation:

Answer:

DIMENSIONS:

THE DOUBLE: 42.6 m cubed on both the length, width, and height

THE HALF: 10.6 m cubed on both the length width and height

THE CUBE: 21.3 m cubedon both the lengrh, width, and height

MOST HEIGHT: The Double at 42.6 m cubed

Step-by-step explanation:

We know that we have 64 m cubed. First, we should find out the volume of each cube. 64 times 2 is 128. This means the Double equals 128 in volume and half of 64 is 32. this means the Half is 32 in volume. Since these are all cubes, every side is exactly the same(or else it would be a rectangle) the formula for finding volume is length times width times height, we would divide EACH of the volumes by 3. 128 divided by 3 is 42.6 meaning the doubles dimensions would be 42.6 on each part of the cube (the lenght width and height would all be 42.6) you can check this by multiplying 42.6 by 3 which takes us back to 128. For the cube we would do 64 divided by 3 which is 21.3 pn every side and 32 divided by 3 is 10.6. The one with the most height is the double. I am not sure how to find the floor space I am super sorry but I hope this helps :)

Answer:

x=−2 and y=−4

Step-by-step explanation:

I will solve your system by substitution.

(Add -4x to both sides)

(Add 48 to both sides)

(Divide both sides by -4)

(Simplify both sides of the equation)

(Add 2y to both sides)

(Add -108 to both sides)

(Divide both sides by 49/2)

(Simplify both sides of the equation)

Answer:

x=−2 and y=−4

Answer:

[tex]y = 5 + x[/tex]

[tex]y - x = 5[/tex]

[tex]x = y - 5[/tex]

Step-by-step explanation:

No options were given but the question can still be solved

Given

From the first statement, we have:

[tex]Maria = x[/tex]

From the second, we have:

[tex]Anika = 5\ more[/tex]

Required

Determine the relationship between the amount of rice they bought

5 more means 5 + Maria.

So, [tex]Anika = 5\ more[/tex] becomes

[tex]Anika = 5 + Maria[/tex]

Substitute x for Maria

[tex]Anika = 5 + x[/tex]

For proper expression, let Anika be y

[tex]y = 5 + x[/tex]

Subtract x from both sides

[tex]y - x = 5[/tex]

Make x the subject

[tex]x = y - 5[/tex]

Answer:

y=27

Step-by-step explanation:

3y+53=7y-55

step 1 add 55 to each side

3y+108=7y

step 2 subtract 3y from each side

108=4y

step 3 divide each side by 4

y=27

Answer:

[tex]x=-1[/tex]

Step-by-step explanation:

1) Subtract 9x from both sides.

[tex]14x+2-9x=-3[/tex]

2)  Simplify  14x+2-9x to 5x+2.

[tex]5x+2=-3[/tex]

3) Subtract 2 from both sides.

[tex]5x=-3-2[/tex]

4) Simplify  -3-2 to  -5.

[tex]5x=-5[/tex]

5) Divide both sides by 5.

[tex]x=-1[/tex]

Therefor, the answer is x = -1

If g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2

The given relationship is:

g(1) = 0

g(n) = g(n-1) + n

g(2) = ?

Since g(1) is already known

g(2)  =   g(1)  +  2

Note that g(1) = 0

Substitute g(1) = 0 into g(2)  =   g(1)  +  2

g(2) = 0  +  2

g(2)  =  2

Therefore, if g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2
