Where would parenthesis need to be placed in the expression to get a value of 44?
(A) 2+3^2×(5−3)
(B) 2+(3^2×5)−3
(C) (2+3^2)×5−3
(D) (2+3)^2×5−3
Answer:
B. 2 + (3^2 * 5) - 3
Step-by-step explanation:
Hey! Sorry for the long wait, I'm still in school and can't really be here 24/7 but I'm proud to announce that I have your answer!
So we have 4 expressions and we need to get our answer to 44. This question already includes the notion that parenthesis placements make a huge difference, so let's review them.
A.2 + 3^2 * (5 - 3)
Use PEMDAS
2 + 3^2 * 2
2 + 9 * 2
2 + 18
20
B.2 + (3^2 * 5) - 3
2 + (9 * 5) - 3
2 + 45 - 3
47 - 3
44
C.(2 + 3^2) * 5 - 3
(2 + 9) * 5 - 3
11 * 5 - 3
55 - 3
52
D.(2 + 3)^2 * 5 - 3
(5)^2 * 5 - 3
25 * 5 - 3
125 - 3
122
As we can see, B. is our answer due to its equivlance to 44.

A company logo is made up of a square and three identical triangles.
What is the area of the logo?
Answer:
[tex]the \: area \: of \: the \: logo \: is \: {91cm}^{2} [/tex]
Step-by-step explanation:
To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.
Area of the square.
To calculate the area of the square you have to calculate the square of one of its sides, following the formula:
[tex]a = {a}^{2} [/tex]
Where "a" is the length of one of its side.
The side length of the square is a=7cm, so its area will be:
[tex]asquare = {7}^{2} \\ asquare = {49cm}^{2} [/tex]
Area of the triangles.
The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.
To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:
[tex]a = \frac{b.h}{2} \\ a = \frac{7.4}{2} \\ a = \frac{28}{2} \\ a = {14cm}^{2} [/tex]
The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:
[tex]atriangles = 3a \\ atriangles = {42cm}^{2} [/tex]
Now that the area of all shape are calculated, you have to add them to determine the area of the logo:
[tex]alogo = asquare + atriangle \\ alogo = 49 + 42 \\ alogo = {91cm}^{2} [/tex]

Write an equation of the line that passes through (−4,−1) and is perpendicular to the line y=4/3x+6.
Answer:
y=-1/4x - 2
Step-by-step explanation:
gradient of perpendicular lines is got by :M1M2= -1
y =4/3x + 6 rearrange 3y = 4x + 18
gradient is 4
4M2 =-1
M2 =-1/4
then is -2
hence y = mx + c is y = -1/4 x -2
Rayna has 5 pounds of ground beef to make hamburgers for a picnic. Each hamburger uses 14 pound of ground beef. How many hamburgers can Rayna make?
Answer:20
We have 5 pounds of ground beef
We are making 1/4 pound hamburgers
Take the number of pounds of beef and divide by the amount of beef per burger and we can determine the number of patties.
5 ÷1/4
Copy dot flip
5 * 4/1
20
We will have 20 patties

3 seconds
5 seconds
30 seconds
50 seconds
Answer:
3 seconds
Step-by-step explanation:

how do i write 152 as a mixed number
Answer: 1 13/25
Step 1: Write down the percent divided by 100 like this:
152% = 152/100
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As 152 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(152,100) = 4. So,
(152÷4)/(100÷4) = 38/25 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 152/100 is also equal to 1 13/25 when expressed as a mixed number.

B.

C.

D.

Activity 2 of 2
Part B: To pay for a concert ticket, Geoff needs to earn $135 in commission. What must Geoff’s sales total for the week?
A.
$13.50
B.
$1,350.00
C.
$135.00
D.
$13,500.00
Part A
Answer: 89.50 dollars
---------------------------
Work Shown:
10% = 10/100 = 0.10
10% of $895 = 0.10*895 = 89.50
=====================================================
Part B
Answer: $1350
---------------------------
Work Shown:
x = amount of sales for the week
10% of x = 0.10*x = 0.10x
0.10x = amount Geoff earns in commission
He needs $135, so 0.10x = 135
Divide both sides by 0.10 to isolate x
0.10x = 135
0.10x/0.10 = 135/0.10
x = 1350
He must have $1350 in sales for the week
The exhaust system of an automobile is first given an emission check and then given a vibration check. The result of an emissions check can be satisfactory (S), marginal (M), or unsatisfactory (U), and the result of a vibration check can be high vibration (H) or low vibration (L) or no vibration (N).
What is the sample space for this situation?
Sample Space = { }
Find the event that the emissions check is satisfactory. Event = { }
Answer:
Step-by-step explanation:
The sample space is known to be the set of all possible outcomes of an experiment we cannot predict its outcome while the event space showcases the subset of the sample space, this may be a collection of outcomes of a random experiment.
From the given information:
The sample space = {SH, SL, SN, MH, ML, MN,UH, UL, UN}
The event that the emissions check is satisfactory = {SH, SL, SN}
