Answer:
85°
Step-by-step explanation:
We need to use the angle fact that angles in a quadrilateral add up to 360° and that a right angle is 90°, using this information we can for an equation to find the value of 1. Lets call "1" x so we don't confuse it with an angle. So,
x + 85 + 100 + 90 = 360
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 90 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
x + 85 + 100 + 90 = 360
→ Simplify equation
x + 275 = 360
→ Minus 275 from both sides to isolate x
x = 85
The measure of angle '1' is 85°
Answer:
85°
Step-by-step explanation:
∠1+85°+100°+90°= 360°
∠1 = 360°- 275°= 85°
∠1 =85°
What value of a makes the equation true
Answer:
The correct answer is -2.
Step-by-step explanation:
it is -2 because if you replaced -2 with a you would have -2 minus 1.5 which is -0.5. -0.5 multiplied by 3 gets you -1.5.
Answer:
Step-by-step explanation:
3(a + 1.5) = -1.5
3a + 3*1.5 = -1.5
3a + 4.5 = -1.5
Subtract 4.5 from both sides
3a + 4.5 - 4.5 = -1.5 - 4.5
3a +0 = - 6.0
3a = - 6
Divide both sides by 3
3a/3 = -6/3
a = -2

for a special 16 sided die, what is the theoretical probability for rolling a number less than 9?
Answer:
8/16
Step-by-step explanation:
there are 16 sides on the dice and there is only 8 number that are less than 9 so that makes it 8/16:)
Answer: There is a 8/16 chance of getting a number under 9.
Explanation: There is a total of 16 sides on the die. If you look at the die numbers 1, 2, 3, 4, 5, 6, 7, and, 8 are all numbers under 9. Which explains how there are 8 sides. Meaning 8 numbers are 8 sides and 16 total numbers are 16 total sides. Therefore the answer is 8/16.

44 is equal to 8 times a number minus 4. what is the number?
Answer:
6
Step-by-step explanation:
Let "a number" = x
44 = 8x - 4
Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First add 4 to both sides:
44 (+4) = 8x - 4 (+4)
44 + 4 = 8x
48 = 8x
Isolate the variable, x. Divide 8 from both sides:
(48)/8 = (8x)/8
x = 48/8
x = 6
6 is your answer.

You and two of your friends go to eat pizza together. There are two deals: 10% off of 1 pizza 30% off of 3 pizzas Do you want to each pay separately and get 10% off of your bill or do you want to split the bill 3 ways and get 30% off of 3 pizzas? Write a paragraph that convinces your teacher which one is the better deal. Show all of the math involved in your calculations.
Please help :(
Answer:
The first one is the better deal.
Step-by-step explanation:
The first one is the better deal =====
30% of 3 = 0.9
0.9 = 90
10% of 1 = 0.1
0.1 = 10
So the better deal would be 10% of 1

Which of the following equation have exactly one solution?
A) 58x + 52 = -78x - 78
B) 58x + 52 = 78x - 78
C) -78x + 52 = -52x - 78
D) 52x + 52 = 52x -78
Answer:
A, B, C all have one solution.
Step-by-step explanation:
1) Each equation in this question has one variable (x). This means that only one solution will be there.
2) Solve for x, you can cross out option D. When you subtract 52x from both sides, you're left with 52 = -78
Which is not true
3) Option A, if solved x = -65/68
4) Option B, x = 13/2
5) Option C, x = 5
All except D, have one solution, I don't know if it's a multiple choice answer but this is how I can help.
Answer:
The answer is A, B, and C.

What type of function is represented in the table? x|0|1|2|3|4|5|
A exponential B logarithmic C linear D quadratic. y|-1|0|-3|-10|-21|-36|
Answer:
This may be wrong but im guessing it is B.logarithmic
Step-by-step explanation:
The type of function is Quadratic.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
x 0 1 2 3 4 5
y - 1 0 - 3 - 10 - 21 - 36
As, we can see from the table ,
The first differences of the y-values are 1, 0, -3, -7, -11, -15, which are not constant.
However, the second differences are all equal to -4, which indicates that the function has a quadratic form.
Hence, the function is quadratic.

What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares whcihh cover a closed figure's surface is its area.
We have, Radius of semicircle = 2 in
So, Area of semicircle = πr²/2
= 3.14/2 x 2/2 x 2 /2
= 1.57 x 1 x 1
= 1.57 mm²
So, the area of the semicircle is 1.57 mm².
Therefore, Radius = 1 in

What is the exact circumference of a circle with a radius of 15 cm? 10πcm 15πcm 30πcm 60πcm WIIL GIVE BRAINLIEST
Answer:
(C) 30πcm
Step-by-step explanation:
In order to find circumference you use the formula C (circumference)=2(pi)(r) in which r is the radius. In this case, two and 15 are thirty so to find the circumference all you have is the equation 30 times pi centimeters is equal to the Circumference.
Answer:
37 pi
Step-by-step explanation:
The circumference of a circle is equal to pi times the diameter.
The formula for the circumference of a circle is C=pi d,and since d = 37 ,we know that C=37 pi.
37 pi =116.238928183,but pi is irrational and the decimal will never end.
Thus,the most exact way to express the circumference is 37 pi.

Three ballet dancers are positioned on stage. Mia is straight behind Jane and
directly left of Christine. If Jane and Mia are 3 meters apart, and Christine and Jane
are 5 meters apart, what is the distance between Mia and Christine?
Answer:3 m
Step-by-step explanation:
Given
Mia is 3 m behind Jane
Mia is left to the Christine
Distance between Mia and Christine is 5 m
Thus they form a right angles triangle shown in fig

CraftWorks employed three different salespeople last year. Person 1 earned
$5500 in the first quarter, person 2 earned $7500 in the first quarter, and
person 3 earned $8000 in the first quarter. What are the maximum FUTA
deductions for the first quarter?
O A. $1229.00
O B. $806.00
O
C. $1302.00
O
D. $1209.00
Answer:
D) $1,209.00
The maximum FUTA deductions for the first quarter = $1,209.00
Step-by-step explanation:
The Federal Unemployment Tax Act (FUTA) is a tax which employers who pay their employees must pay in order to fund the state unemployment agencies. This tax is only payable on the first $1,500 to $7,000 on each emoloyees wage in a single quarter.
The FUTA current rate is 6.2%
Given that,
Employee 1 earned $5,500 in quarter 1.
Employee 2 earned $7,500 in quarter 1.
Employee 3 earned $8,000 in quarter 1.
Employee 2 and employee 3 would only be charged for their first $7,000 since they earned more than $7,000.
Therefore, the maximum FUTA deductions for the first quarter would be calculated as:
(0.062 * 5,500)+(0.062 * 7,000) + (0.062 * 7,000)
= $341 + $434 + $434
= $1,209
The maximum FUTA deductions for the first quarter = $1,209.00
