Jackson is comparing two squares. The first square has an area of 64 cm2. The second square has an area of 121 cm2. What is the difference in the perimeters of the two squares in centimeters?
Answer:
12 cm difference
Step-by-step explanation:
√64 cm² = 8 cm
8 cm x 4 = 32 cm perimeter
√121 cm² = 11 cm
11 cm x 4 = 44 cm perimeter
44 cm - 32 cm = 12 cm difference

Since it's 2 in a row, it is divided by 4
technically it depends on the way you flip the coin, its mostly a 50-50
a more answer-y answer to this would be around (heads) 65-35 (tails) in my opinion.
A polynomial of degree 3 is multiplied by a polynomial of degree 5. What is the degree of the product?
Answer:
8
Step-by-step explanation:
The degree of a polynomial refers to the term with the highest exponent. Thus the highest exponent in a degree 3 polynomial is x3; for a degree 5 polynomial, it's x5. When you multiply
x3*x5 = x3+5 = x8.
So the product of a degree 3 polynomial and a degree 5 polynomial is a degree 8 polynomial.
Your leading term will result from the 3-degree term of the first polynomial, and the 5-degree term of the second. So you'll have something like ax3 * bx5. That will result in x3*x5=x8, so your product will have degree 8.
What is the difference of the value of Lily's expression , 6x-3, when x=5 and the value of Pedro's expression when x=5 ? Show or explain how you got your answer.
Given Info : What is the difference of the value of Lily's expression , 6x-3, when x=5 and the value of Pedro's expression when x=5 .
To Find :- Show or explain how you got your answer.
Solution:-
The expression is 6x-3 , and we need to find its value at x = 5 , On putting x =5 we have
6*5-3 = 30-3 = 27.
This value will come same in case of Pedro, therefore our required answer is 5
When a number is multiplied by 5 before subtracting from 78 the result obtained is the same as three times the sum of the number and 5 find the number
Answer:
x = 7.875
Step-by-step explanation:
Let the number = x
When a number is multiplied by 5 before subtracting from 78 the result obtained is the same as three times the sum of the number and 5 find the number
Hence,
78 -(x × 5) = 3(x + 5)
Expand the brackets
78 - 5x = 3x + 15
Collect like terms
78 -15 = 3x + 5x
63 = 8x
x = 63/8
x = 7.875

A store owner buys a case of 144 pens for $28.80. He sells the pens for $0.40 each. The owner claims that they marked the pens up by 50% before selling them. Prove that the owner calculated their markup correctly. If they did not, how much of a markup actually occurred?
Answer: $0.3
Step-by-step explanation:
Given
The owner buys 144 pens for $28.80 i.e. each pen costs
[tex]\dfrac{28.80}{144}=\$0.2[/tex]
owner sells the pen at $0.4 i.e. price marked up by
[tex]\Rightarrow \dfrac{0.4-0.2}{0.2}\times 100=100\%[/tex]
So, the claim of the owner is incorrect
The actual increase in the price to get 50% markup
[tex]\Rightarrow 0.2\times (1+0.5)=\$0.3[/tex]

evalute sin 60. cos 30 sin +sin 30 .cos 60 what is the value of sin(30-60) what can you conclude
Answer:
See explanations below
Step-by-step explanation:
evaluate sin 60. cos 30 sin +sin 30 .cos 60 what is the value of sin(30-60) what can you conclude
According to the trigonometry identity
Sin 30 = 1/2
Sin 60 = √3/2
Cos 30 = √3/2
Cos 60 = 1/2
sin 60. cos 30 +sin 30 .cos 60
= √3/2(√3/2) + 1/2(1/2)
= √9/4 + 1/4
= 3/4 + 1/4
= 4/4
= 1
sin(30-60) = sin30cos60 - cos30sin60
sin(30-60) =1/2(1/2) - √3/2(√3/2)
sin(30-60) = 1/4 - √9/4
sin(30-60) = 1/4 - 3/4
sin(30-60) = (1-3)/4
sin(30-60) = -2/4
sin(30-60) = -1/2
hence the former fraction gives a positive values while the later gives a negative

Model with mathematics:
a) cranes = 40 panthers = 40
b) yes, finding the mean is a good way of determining which team has the better record, because "finding the mean" is just finding the average.
Step-by-step explanation:
Financial Literacy:
24 = [tex]\frac{x+15+20+10+12+20+16+80+18}{9}[/tex] → [tex]24 = \frac{191}{9}[/tex]
24×9=x · 191
→ 216 = x · 191
→ 216-191=x
x = 25

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer: x = 10
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°.
(2x + 3) + (5x + 17) + 90 = 180
2x + 3 + 5x + 17 + 90 = 180
7x + 110 = 180
7x = 70
x = 10

I am trying to do a practice test to prepare for my real test tomorrow and I don't understand the question. Can anyone help explain it plz any help would be great.
Step-by-step explanation:
in 50 item test nestor got 95% correctly. how many correct answers did he get
Answer: 47.5 or just 47
Step-by-step explanation: Well, to start, set up a ratio.
x / 50 = 95 / 100
95 * 50 is 4750
4750 / 100 is 47.5.
Now, it's asking how many questions he got correct. You can't get 47.5 questions correct, it should be a whole number. Now, I don't know how the rules work with that question, but it is like 47.
