m_ABD = 2x + 7
m2 DBC = 3x – 17
Solve for x and find m2 ABD.
Answer:
x= 24, <ABD = 55°
Step-by-step explanation:
The way I go to x=24 is in the picture, but to find <ABD is a piece of cake, just take its value (2x+7) and replace the x with 24 and then you will get 55°

Susan is buying supplies for a party. Spoons only come in bags of 2 and forks only come in bags of 16. What is the least number of spoons and the least number of forks she can buy so that she has the same number of each?
Answer:
She needs to get 8 bags of spoon and 1 bag of fork
Step-by-step explanation:
Here in this question, we want to know the least number of spoons and the least number of bags to be bought so that there are same number of each.
Basically, to calculate this, we need the lowest common multiple of 16 and 2. The lowest common multiple of both is 16 (2 is a factor of 16)
So the lowest number of each she can buy to have the same number of pieces is 16.
Kindly recall that spoons come in bags of 2. So to achieve the 16, she needs 8 bags.
Since fork comes in bag of 16, to achieve 16, she only need a single bag of fork.
Two functions represent the composite function h(x) = (x – 1)³ + 10 so that h(x) = (g compose f)(x). Given f(x) = x + a and g(x) = x³ + b, what values of a and b would make the composition true? a = b =
Answer:
a = -1 and
b = 10
Step-by-step explanation:
Given:
h(x) = (x – 1)³ + 10
h(x) = (g compose f)(x).
f(x) = x + a and
g(x) = x³ + b
To find:
The values of a and b = ?
Solution:
First of all, let us have a look at the composite functions.
(g compose f)(x) means we replace the value of [tex]x[/tex] with [tex]f(x)[/tex] in the function [tex]g(x)[/tex].
We know that:
[tex]g(x) =x^3+b[/tex] and
[tex]f(x) = x + a[/tex]
Let us find (g compose f)(x) by replacing [tex]x[/tex] with [tex]x+a[/tex]
[tex](g\ compose\ f)(x) = (x+a)^3+b[/tex]
Also, h(x) = (g compose f)(x) = (x – 1)³ + 10
Therefore,
[tex](x - 1)^3 + 10 = (x+a)^3+b[/tex]
Comparing the corresponding elements of the above expressions:
we get a = -1 and
b = 10
Answer:
a: -1
b: 10

The situation that is an example of an observational study is " Having customers fill out a questionnaire about their favourite brand of toothpaste".
What is an observational study?When researchers monitor the effect of a risk factor, diagnostic test, therapy, or other intervention without attempting to influence who is or is not exposed to it in observational studies.
For example: Consider someone standing on a popular street in a New York neighbourhood asking passers-by how many dogs they have, then analyzing the data to see if more pet food businesses are needed in the area.
As we know that in an observational study, the sample whose test/survey is been taken is completely random.
Therefore, the situation that is an example of an observational study is " Having customers fill out a questionnaire about their favourite brand of toothpaste".

CAN SOMEONE PLEASE HELP ME FIND THE AREA OF A HEXAGON
Answer:
the answer is 57.12
Step-by-step explanation:
so the area of the rectangle is 74.24, thats where you get the 8 x 9.28, which is important. so next we're going to go is 9.28-5 which equals 4.28, and that is what the total bottom of 2 triangles would be, (if you drew a rectangle around it). the you would divide 4.28 by 2 to get 2.14, which is the value of 1. next you do 2.14 x 4 and get 8.56. then divide 8.56 by 2 and get back to 4.28. you take 4.28 and multiply it by 4 to get 17.12. from there on you do, 74.24 - 17.12 and get 57.12.
if a+b+c=2 , ab+bc+ac= -1 and abc = -2 , then find the value of a^3 + b^3 + c^3
Answer: 8
Step-by-step explanation:
EQ1: a + b + c = 2 --> b + c = 2 - a
EQ2: ab + bc + ac = -1 --> b + c = (-1 - bc)/a
EQ3: abc = -2 --> bc = -2/a
Set EQ1 = EQ2 and substitute bc using EQ3 to solve for "a":
[tex]2-a=\dfrac{-1-bc}{a}\\\\\\\text{Clear the denominator:}\\a(2-a)=-1-bc\\\\\text{Substitute bc:}\\a(2-a)=-1-\dfrac{-2}{a}\\\\\\\text{Clear the denominator:}\\a^2(2-a)=-a+2\\\\\\\text{Simplify and set equal to 0:}\\2a^2-a^3=-a+2\\0=a^3-2a^2-a+2\\\\\text{Factor:}\\0=a^2(a-2)-1(a-2)\\0=(a^2-1)(a-2)\\\\\text{Solve for a:}\\a^2-1=0\qquad a-2=0\\a=\pm1}\qquad \qquad a=2[/tex]
Consider the solution a = 2 and plug it into EQ1 to solve for "b"
b + c = 2 - 2
b + c = 0
b = -c
Plug in a = 2, b = -c, and c = c into a³ + b³ + c³
2³ + (-c)³ + c³
= 8 - c³ + c³

Step-by-step explanation:
As per the order of operations, you do the parentheses first. g(5) is inside the parentheses of f(g(5)).
g(5) = -3(5) +5 = -10
Then ...
f(g(5)) = f(-10) = 2(-10) +7

a retailer sold a shirt for rupees 1000 and he made a profit of 25% find the purchased price of a shirt
Answer:
750 rupees is used to make shirt
250 rupees is profit
Step-by-step explanation:
If the retailer sold the shirt for 1000 rupees and got 25% profit then that means 1/4 is profit and 3/4 is how much the retailer spent to make the shirt.
So 1000 times 3/4 is 750 which is how much the shirt really cost and
1000 times 1/4 is 250 and that is the retailers profit.

?/24 A refrigerator is priced at $525.50. There is a 7% sales tax rate. What is the sales tax for the refrigerator in dollars and cents? Round to the nearest penny
Answer: The sales tax is $36.79
Step-by-step explanation:
Multiply the sales tax percent by the money to find how much the sale tax is.
7% * 525.50 = 36.785 which rounds to 36.79 to the nearest penny.
The required amount of sales tax for the refrigerator is $36.785.
As mentioned in the question, a refrigerator is priced at $525.50. There is a 7% sales tax rate. The sales tax for the refrigerator in dollars and cents is to be determined.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
The total price of the sales tax = $525.50
Sales tax is 7%,
sales tax= 525.50 × 7%
sales tax = $36.785
Thus, the required amount of sales tax for the refrigerator is $36.785.

4(-8x + 5) – (-33x – 26)
Answer:
1x+46 is the answer
Step-by-step explanation:
=4(-8x + 5) – (-33x – 26)
opening brackets to simplify
=-32x+20+33x+26
=-32x+33x+20+26
=1x+46 is the answer
hope it will help :)
Answer:
x+46
Step-by-step explanation:
4(-8x + 5) – (-33x – 26)
The first step is to distribute and simplify.
4 distributed to -8x will be -32x, and same thing goes with 5, which is 20.
-
The first part of the equation is -32x+20
Now, this is where it gets confusing.
If there is a sign before a pair of parentheses, you always put 1. In this case, it's -1 distributed to -33x and -26.
So, the second part of the expression will be +33x+26
The whole expression is
-32x + 20 + 33x + 26
add like terms, -32x+33x= x.
20+26=46.
The answer is x+46.
If h(x)=x^2-5x, g(x)=2x, f(x)=3x-2, what is h(f(g(x)))
Step-by-step explanation:
start from f(g(x))
f(g(x))= 3(g(x)) -2
f(g(x))= 6x -2
h(f(g(x)))=(f(g(x)))² -5(f(g(x)))
h(f(g(x)))=(6x-2)² -5(6x-2)
h(f(g(x)))=36x²-24x+4-(30x-10)
h(f(g(x)))=36x²-24x+4-30x+10
h(f(g(x)))=36x²-54x+14

solve the equation 7+4y=39
Answer:
y = 8Step-by-step explanation:
[tex]7+4y=39\\\\\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}\\7+4y-7=39-7\\\\\mathrm{Simplify}\\4y=32\\\\\mathrm{Divide\:both\:sides\:by\:}4\\\frac{4y}{4}=\frac{32}{4}\\\\Simplify\\y =8[/tex]
Answer:
y = 8
Step-by-step explanation:
7 + 4y = 39
Rearrange:
4y + 7 = 39
Subtract 7 from both sides:
4y + 7 = 39
- 7 -7
4y = 32
Divide both sides by 4:
4/4 = y
