Lucas works for a salary of $2,396 per month. His deductions include $360 of federal income tax, $148 for Social Security, $35 for Medicare, and a $95 insurance premium. What is his monthly net pay?
Answer:
Lucas monthly net pay is $1758
Step-by-step explanation:
Lucas works for a salary of $2,396 per month.
His deductions include $360 of federal income tax,
$148 for Social Security,
$35 for Medicare, and
a $95 insurance premium.
Now,
2396 - 360 - 148 - 35 - 95 = 1758
Thus, Lucas monthly net pay is $1758

Translate algebra expressions 2 less that 3 times z
Answer:
(3z) - 2
Step-by-step explanation:
Let's see an example:
(4x) - 6
This translates into 6 less than 4 times x
So... 2 less than 3 times z =
(3z) - 2
Answer:
Step-by-step explanation:
That would be "3z - 2:" 2 less than 3 times z.

Which graph represents a function with a domain of all numbers greater than or equal to -7 and less than 2? Your explanation should include all information about reading domain on a graph given the limitations. As well as how the different circles affects the notation on the graph when equal to and not equal to are used.
Answer: D.
Step-by-step explanation:
The way to know if it is “greater than or equal to” opposed to jsut greater than is to look at the dot. If it is filled in it is “equal to” if not it isn’t.

area of shaded sector =
area of unshaded sector =
Answer:
Area of the unshaded sector = 113.4 sq units
Area of the shaded sector = 200.6 sq units
Step-by-step explanation:
First let us calculate the area of the circle
Area of the circle = πr²
radius r = 10units
Area of the circle = π(10)²
Area of the circle = π(100)
Area of the circle = 3.14(100)
Area of the circle = 314 sq. units
Area of a sector = theta/360 * πr²
Area of the unshaded sector = 130/360 * 314
Area of the unshaded sector = 13/36 * 314
Area of the unshaded sector = 113.389 sq units
Area of the unshaded sector = 113.4 sq units
Area of the shaded sector = Area of circle - Area of the unshaded sector
Area of the shaded sector = 314 - 113.89
Area of the shaded sector = 200.6sq. units

A. 85/c
B. c/17
C. c/8.5
D. 17/c
Interpreting as: circle 8.5 inches.
Assuming
"circle"
is a geometric object
circle | radius 8.5 inches
Equation:
(x - x_0)^2 + (y - y_0)^2 = 72.
(assuming center (x_0, y_0))
Properties:
diameter | 17 inches
area enclosed | 227 in^2 (square inches)
circumference | 53.4 inches
answer is D. 17/C

Tyler has a stack of cards. He picks a card, records the color, and returns the card to the stack. He repeats this 60 times and chooses a red card 24 times. What is the experimental probability of choosing a red card from the stack?
Answer:
24/60 = 2/5
Step-by-step explanation: dont have one
Answer:
2/5, or 40%
Step-by-step explanation:
The experimental probability is not what the mathematical probability of something always is of happening, but rather the probability based on the pattern of given data in a given experiment. So rather than giving the likelihood of picking a red card on the next pick, you would instead give the "likelihood" of picking a red card based on the trend found in the given data. This would amount to 24/60 which, simplified, would be 2/5, or 40%.

Which of the following is a solution to the system of
equations?
4 + y = -x
y = 2x - 10
Answer:
x=3, y= -6
Step-by-step explanation:
make 4+y= -x as equation (1) and make y=2x-10 as equation (2, then you must find a third equation either from equation (1)or (2). If you choose to find equation (3) from (2) it will be y=2x-10 , then substitute equation (3) from (1) because you can't choose (2) , then it will be 4+(2x-10)= -x
the answer will be x =2
substitute x from equation (3)
y=2x-10
y=2 (2)-10
y= -6
4/5 - 1/10=
A. 7/10
B.3/5
C.3/10
D.2/25
Answer
A 7/10
Step-by-step explanation:
if you make it even, you double the 4/5 to make it a 8/10, if you every have a number that is like 4/6-2/18, you triple the 4 to make 12, and triple the 6 to make it 18. so you now have 12/18-2/18=10
So 8/10-1/10=7/10
The drama club held a car wash on Saturday and Sunday. They washed a total of 60 cars. If they washed 24 cars on Sunday, what percent of the cars did they wash on Sunday?
Answer: 2.5%
Step-by-step explanation:
60 divided by 24 equals 2.5
Answer:
24
Since they washed a total of 60 cars, then according to the question they washed 40%(40 per cent) of 60 cars on Sunday.

3. A 42 ft tall tree casts a 15 ft shadow, what is the
angle of elevation to the sun?
Answer:
19.64°
Step-by-step explanation:
The angle of elevation can be calculated as follows
Tan ©= 15/42
= 0.357
= tan-1 0.357
= 19.64°
Hence the angle of elevation is 19.64°
Find an exponential equation that passes through the points (0, 4) and (2, 9).
Given:
An exponential equation passes through the points (0,4) and (2,9).
To find:
Exponential equation that passes through the given points.
Solution:
Let the required exponential function is:
[tex]y=ab^x[/tex] ...(i)
The function passes through the points (0,4) and (2,9). It means the above equation must be true for these points.
[tex]4=ab^0[/tex]
[tex]4=a(1)[/tex]
[tex]4=a[/tex]
And,
[tex]9=ab^2[/tex]
Substituting [tex]a=4[/tex], we get
[tex]9=(4)b^2[/tex]
[tex]\dfrac{9}{4}=b^2[/tex]
[tex]\pm \sqrt{\dfrac{9}{4}}=b[/tex]
[tex]\pm \dfrac{3}{2}=b[/tex]
In an exponential function b>0. So, [tex]b=\dfrac{3}{2}[/tex].
Putting [tex]a=4,b=\dfrac{3}{2}[/tex] in (i), we get
[tex]y=4\left(\dfrac{3}{2}\right)^x[/tex]
Therefore, the required exponential function is [tex]y=4\left(\dfrac{3}{2}\right)^x[/tex].

Answer:
Isosceles and Right
Step-by-step explanation:
An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.
Answer:
Isosceles and right
Step-by-step explanation:
We have a picture of triangle and are asked to name it, look at definitions below :
Isosceles - Geometrical figure with three sides and three angles
Right - Triangle where one angle is a right angle (90°)
Scalene - Triangle where all three sides have different lengths
Acute - Triangle where all three sides are less than 90°
If we look at the triangle, we can tell that it has three sides and three angles, therefore isosceles must be in one of the answer choices. Crossing out the options scalene and acute / scalene and right.
Now we have two options and we need to determine whether this triangle is an acute triangle or is a right triangle.
To figure out so we can look at the angle in the bottom left, which when measures equals to 90°. Therefore making it a right triangle and crossing out the other option.
Our answer left is Isosceles and Right.
