What is the value of a?
Answer:
a=22
Step-by-step explanation:
2a+2=46
2a=46-2
2a=44
a=44÷2
a=22
Answer:
a = 22°
Step-by-step explanation:
Since vertical angles are always congruent we know that 46° = 2a + 2°, therefor...
46° = 2a + 2°
2a = 46° - 2°
2a = 44°
a = 44° / 2
a = 22°
What is twice the difference of a number and 6 is 5
Answer:
8.5
Step-by-step explanation:
Twice the difference of a number and 6 equals 5 is written algebraically as 2(x-6)=5, where x is the number. Solving for x:
2(x-6)=5
(x-6)=5/2
x=6+5/2
x=17/2
So the number is 17/2, or, expressed as a decimal number, 8.5
Use the Distributive Property to solve the equation.
3 = 3/4 ( b - 8 )
Answer:
b = 12
Step-by-step explanation:
First, distribute 3/4 to both terms in the parentheses:
3 = 3/4(b - 8)
3 = 3/4b - 6
Now, solve for b:
9 = 3/4b
12 = b
So, the answer is b = 12
Answer:
12
Step-by-step explanation:
3 = 3/4 x (b-8)
Distribute 3/4 through the parentheses
3 = 3/4 b - 6
Multiply both sides of the equation by 4
12 = 3b - 24
Move the variable to the left - hand side and change its sign
-3b = -24 - 12
Calculate the difference
-3b = -36
Divide both sides of the equation by -3
B = 12

D
Step-by-step explanation:
Remark
The two angles across from each other are equal.
Equation
5x - 1 = 124 Add 1 to both sides

A 7th grade classis selling packages of cotton candy at a festival for $2.95 each. Each package costs them $0.95 to make.They expect to sell between 900 and 1,000 packages of cotton candy during the festival.What is a reasonable estimate of the class’s profit?
A. $900
B. $1,000
C. $2,000
D. $3,000
Answer:
Answer C.
Step-by-step explanation:
The class sells them for $2.95, assuming $0.95 manufacturing cost per, leaving $2.00 profit per bag. If they sell 900-1000 packages at $2.00, it leaves $1800-$2000 profit.
Answer:
if you see they have 2.95 and 0.95 you need to combert to a decimal and then you need to subtract 900 and 1,000
Step-by-step explanation:

a biologist analyzes 15 bacteria samples each day a. complete the table
Answer:
Day 1=15 Day 2=30 Day 3=45 Day 4= 60 Day 5= 75. The expression is N+15
Step-by-step explanation:
The complete table:
Days 1 2 3 4 5
Total samples 15 30 45 60 75
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of bacteria samples analyze each day = 15
The equation for the number of bacteria analyzes after x days.
B = 15x
Now,
x = 1, B = 15
x = 2, B = 30
x = 3, B = 45
x = 4, B = 60
x = 5, B = 75
Thus,
Days 1 2 3 4 5
Total samples 15 30 45 60 75

Answer:
3/8
Step-by-step explanation:
First convert 1/2 into eights. 1/2 as eighths is 4/8.
So 4/8-1/8=3/8.
Therefor, 3/8 is the answer you're looking for.
I hope I helped :)
Answer:
3/8
Step-by-step explanation:
you have to find the LCM (least common multiplier) of 2,and 8 and that would be 8 therefore youd change the fractions from 1/2-1/8 to 4/8-1/8 you subtract the tops and keep the bottoms the same as 8. so 4-1=3 therefore the anwser would be 3/8

Mr. Moore deposits $3,550 in a money market account with an interest rate of 22%. If he does not deposit or withdraw any money from the account, how much will he have at the end of 9 months?
Answer:
$10,579, assuming that 22% is the rate per month
Step-by-step explanation:
Here, I'll assume that the interest rate is per month.
The simple interest formula is [tex]I=Prt[/tex] (Interest = principal * rate * time). The rate and time need to use the same units.
The principal is $3550, the rate is 0.22, and the time is 9, so [tex]I=(3550)(0.22)(9)[/tex]. The product is 7029.
This is added to how much money he already has: 7029+3550=10579

A verandah of width 2.25 m is constructed all along outside a room which is 5 m long and 3 m wide. Find:
(1) the area of verandah and
(ii) the cost of cementing the floor of verandah at the rate of 7 275 per m².
who answers first will be marked as brainliest iam serious no scam
Answer:
(i)The length of room = 5.5 m and width of the room = 4 m
The length of room with verandah = 5.5 + 2.25 + 2.25 = 10 m
The width of room with verandah = 4 + 2.25 + 2.25 = 8.5 m
Area of verandah = Area of room with verandah – Area of room without verandah = Area of ABCD – Area of EFGH = (AB x AD) – (EF x EH) = (10 x 8.5) – (5.5 x 4) = 85 – 22 = 63 m2
(ii) The cost of cementing 1 m2 the floor of verandah = Rs 200 The cost of cementing 63 m2 the floor of verandah = 200 x 63 = Rs 12,600
