Can anyone answer these questions?
Answer:
1. y² = 169
taking a square root of both sides
y = √169
we know that 13 * 13 = 169
since when squaring a number, the signs on the numbers do not matter
(i.e - 2* 2 = 4 and (-2)*(-2) = 4)
So (-13) * (-13) = 169 as well
Hence we can say that √169 = ±13 OR √169 = +13 and -13
2. Volume of a cube-shaped crate = side*side*side
Volume = side³
(We are given that volume = 27)
27 = side³
side = ∛27
Since 3*3*3 = 27 and (-3)*(-3)*(-3) = 27
So, we can say that ∛27 = ± 3
BUT
the side of a crate cannot be negative, so the side will NOT be -3 and hence,
side = 3
3. b³ = 1000
we know that 10*10*10 = 1000 and (-10)*(-10)*(-10) = 1000
So, ∛1000 = ∛(10*10*10)= ±10
4. Area of a square(Patio) = Side²
Area = Side²
196 = Side² (Since we are given the area of the patio)
Side = √196 = √(14*14) or √(-14*-14)
Hence,
Side = + 14 or -14
but the side of a patio cannot be negative
Side = +14 ft
Each of the 25 students in Mr. McDonald’s class sold 16 raffle tickets. If each ticket costs $15, how much money did Mr. McDonald’s students raise.
Answer:
$6,000
Step-by-step explanation:
Basically just multiply 25*16 to see how many raffle tickets the class sold in total (400). Then to find the amount of money they raised, multiply 400*15 (6,000).
In analyzing hits by certain bombs in a war, an area was partitioned into regions, each with an area of km2. A total of bombs hit the combined area of regions. Assume that we want to find the probability that a randomly selected region had exactly hits. In applying the Poisson probability distribution formula, P(x) , identify the values of , x, and . Also, briefly describe what each of those symbols represents.
Answer:
The answer is "[tex]\bold{ \mu =0.967, x=3, \ and \ e= 2.718}[/tex]".
Step-by-step explanation:
A distribution of poulet applies because it deals through events (bomb hits) over even a sample space (the region with [tex]0.95 \ km^2[/tex] area).
Its average hit number per area is:
[tex]\to \mu = \frac{\text{Number of hits of bomb}}{ \text{number of regions number}}[/tex]
[tex]=\frac{535}{553} \\\\= 0.967 \\\\[/tex]
[tex]\to x = 3\\\\\to e = 2.718[/tex]

Step-by-step explanation:
Mr. Frankel bought 5 tickets to a puppet show and spent $26. He bought a combination of child tickets for $2 and adult tickets for $10 each. Write a system of equations to determine the number of adult tickets, a, and the number of child tickets, c, he bought. Solve the system. *Show both the equations and solutions
Answer:
3 child tickets and 2 adult tickets
Step-by-step explanation:
5t = 26
2c + 10a = 26
c = 3 a = 2
(2 * 3) + (10 * 2) = 26
6 + 20 = 26
The equations are c + a = 5 and 2c + 10a = 26. Then the number of children and adults will be 2 and 3, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Mr. Frankel bought 5 tickets to a puppet show and spent $26. He bought a combination of child tickets for $2 and adult tickets for $10 each.
Let 'c' be the number of children and 'a' be the number of adults. Then we have
a + c = 5 ...1
2c + 10a = 26 ...2
From equations 1 and 2, then we have
2(5 - a) + 10a = 26
10 - 2a + 10a = 26
8a = 16
a = 2
Then the value of the variable 'c' is calculated as,
2 + c = 5
c = 3
The equations are c + a = 5 and 2c + 10a = 26. Then the number of children and adults will be 2 and 3, respectively.

Dan orders supplies for the science lab. Each of the 30 stations in the chemistry lab needs 5 feet of rubber tubing. If rubber tubing sells for $8.25 per yard, how much will it cost to equip all stations?
It will cost $412.50 for equipment for all stations.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Dan orders supplies for the science lab. Each of the 30 stations in the chemistry lab needs 5 feet of rubber tubing. If rubber tubing sells for $8.25 per yard.
The cost will be calculated as below,
3 feet = 1 yard
5 x 30 = 150 feet
8.25 per yard = cost
150/ 3 = 50 yards (total tubing needed)
50 x 8.25 = $ 412.50

Mitchell’s dog is 1/3 as old as Katie’s cat. The sum of their ages is 12 years. How old is Mitchell’s dog?
Answer:
Mitchell's dog is 3 years old
Step-by-step explanation:
9 x 1/3 = 3
9 + 3 = 12
To solve this I just thought of the multiples of three under 12 that if added to 3 are equal to 12 to find Katie's cat age. The multiples of three under 12 are 3, 6 and 9. It couldn't be 3 and 6+3=9 so it had to be 9. So if Katie's cat is 9, you just multiply 9 by 1/3 or divide it by 3 to find Mitchell's dog age.

Use the given x and y values to write a direct variation equation
x=5, y=30
Answer:
The direct variation equation is y = 6x
Step-by-step explanation:
The direct variation equation is y = kx, where
k is the constant of variationTo find the value of k, use the initial values of x and y
∵ y = 5, y = 30
∵ y = k x
→ Substitute the values of x and y to find k
∵ x = 5 and y = 30
∴ 30 = k (5)
∴ 30 = 5k
→ Divide both sides by 5
∴ [tex]\frac{30}{5}=\frac{5k}{5}[/tex]
∴ 6 = k
→ Substitute it in the form of the equation
∴ y = 6x
The direct variation equation is y = 6x

Find the slope of the line that passes through the points: (1, 1) and (7, 5) . If you get stuck , try plotting the points on graph paper and drawing the line through them with a ruler.
Answer:
2,3
Step-by-step explanation:
The slope of the line that passes through points (1, 1) and (7, 5) is 2/3.
What is slope ?Slope is a notation that shows that a surface of which one end or side is at a higher level than another surface.
The formula for slope of a line that passes through two points (x₁.y₁) and (x₂,y₂) is,
y₂ - y₁ = m(x₂ - x₁)
The given points are, (1, 1) and (7, 5).
The slope of the line is given by formula m = (y₂-y1)/(x₂-x₁)
m= (5-1)/(7-1)
m = 4/6
m = 2/3
The slope of the line that passes through points (1, 1) and (7, 5) is 2/3.

Step-by-step explanation:
Notice: The literal factors are all the combinations of a and b where the sum of the exponents is 4: a4, a3b, a2b2, ab3, b4.
The degree of each term is 4.
The first term is actually a4b0, which is a4 · 1.
Thus to "expand" (a + b)5, we would anticipate the following terms, in which the sum of all the exponents is 5:
(a + b)5 = ? a5 + ? a4b + ? a3b2 + ? a2b3 + ? ab4 + ? b5
The question is, What are the coefficients?
They are called the binomial coefficients. In the expansion of
(a + b)4, the binomial coefficients are
1 4 6 4 1
The coefficients in the expansion are 1, 4, 6, 4, 1.
What is Binomial Expansion?The sum of exponents of x and y is always n. The binomial coefficients which are equidistant from the beginning and from the ending are equal i.e. [tex]^nC_0[/tex]= [tex]^nC_n[/tex], [tex]^nC_1[/tex]= [tex]^nC_{n-1}[/tex], [tex]^nC_2[/tex]= [tex]^nC_{n-2}[/tex] ,….. etc.
The expansion of [tex](x+ y)^4[/tex]
= [tex]x^4[/tex] + 4x³y + 6x²y² + 4xy³ + [tex]y^4[/tex]
So, the highest degree is 4.
and, The literal factors are all the combinations are [tex]x^4[/tex], 4x³y, 6x²y², 4xy³,[tex]y^4[/tex]
Hence, the coefficients in the expansion are 1, 4, 6, 4, 1.

What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
Given that,
The number of employees laid off last year was 75.
The percentage increase in laid off for present year is 20%.
The number of employees laid off can be calculated as follows,
75 + 20% of 75
= 75 + 20/100 × 75
= 75 + 15
= 90
Hence, the number of employees laid off in the present year is 90.
