Do 42 and 43 pleasee
Answer:
42. A
43. C
Step-by-step explanation:
42. The answer is A. This is because we are distributing (multiplying) the 7.2 to each number in the parentheses.
43. If Hal ran 4.5 laps, then he ran...
0.65 mil (since each lap is 0.65 miles)* 4.5 (laps) = C. 2.925 miles.
Answer:
42. A, distributive property tells us how to solve expressions in the form of a(b + c).
43. 0.65 miles x 4.5 laps = 2.925, C

In a camp ,there is enough flour for 300 persons for 42 days.How long will the flour last if 20 more persons join the camp
Answer/Step-by-step explanation:
Direct proportion: If a variable increases then other variable also increases with a constant factor i.e. y = kx
Inverse proportion: if a variable increases then other variable decreases with a constant factor i.e xy = k
Assume that food will last for d days if 20 more persons join the camp.
Understand the fact that for given food number of days food last is inversely proportional to the number of persons hence product of days food lasts and number of persons is constant,
Days x number of persons = constant
Equate the product of 300 persons and 42 days with (300 + 20) person and d days to solve for d.
[tex](300+20) *d=300*42[/tex]
⇒ [tex]d = \frac{12600}{320}[/tex]
⇒ [tex]d =\frac{1260}{32}[/tex]
⇒ [tex]d=\frac{315}{8}[/tex]
⇒ [tex]d=39.375[/tex] [tex]days[/tex] [tex]or[/tex] [tex]39(\frac{3}{8} )days[/tex] [tex]in[/tex] [tex]fraction[/tex]
Hence, if 20 more people Join (320 people ) it will last 39.375 days in decimal or 39 3/8 days in fraction

Polynomial
Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.
Polynomials are classified based on degree as linear, quadratic, cubic and so on.
Given the polynomial:
(x + 2y - 6)(x - y + 5) = x² + 2xy - 6x - xy - 2y² + 6y + 5x + 10y - 30
= x² - x + xy + 16y - 2y² - 30

You and your friend leave your houses at the same time to meet at a restaurant. The distance (in miles) your friend
is from the restaurant is given by y = -40% + 200, where I is the number of hours since your friend left home.
You live 100 miles from the restaurant and arrive at the same time as your friend. Write a linear equation that
represents your distance from the restaurant
Answer:
When x=0 the friend is 200 miles from the restaurant and at x=5 the friend reaches the restaurant. When x=0 you are 100 miles from the restaurant, so 100 is the y intercept, and when x=5 you reach the restaurant so 5 is the x intercept. We have y=mx+100 and y=0 when x=5, so 0=5m+100 therefore m=-20 and the equation is y=-20x+100.

17 is what percent of 68?
Answer:
25%
17 is what percent of 68?
Its 25%
17/68*100
= (17*100)/68
= 1700/68 = 25
Answer:
25%
Step-by-step explanation:
Question : 17 is what percent of 68?
Answer :
To solve this let the unknown percentage be x .
Let us solve now.
68 × x% = 17
68 × [tex]\frac{x}{100}[/tex] = 17
And now let us find the percentage by making x as the subject.
[tex]x=\frac{17*100}{68}[/tex]
[tex]x = \frac{1700}{68}[/tex]
[tex]x =25[/tex]
Therefore, the percentage is 25%

The diameter of a circle field is 40m and that of another 96m . find the diameter of the circular field whose area is equal to the sum of the area of two fields
Answer :
According to the Question
Diameter of a circle field is 40m and that of another 96m .
We have to find the diameter of the circle whose area is equal to the sum of the area of given two circular fields.
Radius of field whose diameter is 40 m
→ r = 40/2 = 20m
Radius of field whose diameter is 96 m
→ r' = 96/2 = 48m
Now, calculating the diameter of Larger circular field.
Let the radius of larger field be R m .
Now, according to the given statement
Sum of Area of given two circular fields = Area of larger field
➠ πr² + πr'² = πR²
➠ π ( r² + r'²) = π R²
➠ 20² + 48² = R²
➠ 400 + 2304 = R²
➠ 2704 = R²
➠ √2704 = R
➠ 52 = R
Therefore, Diameter = 2 × R = 2×52 = 104 m
So, the diameter of Larger circular field is 104 m .
Answer:
Diameter of the circular field=40 m[tex]r = \displaystyle{ \frac{40 \: m}{2}} [/tex][tex]r=20 m[/tex]Diameter of another circular field=[tex]96 m[/tex]r=[tex]\displaystyle{\frac{96 m}{2}}[/tex]r=48 mArea of circular field(2)=[tex]πr^2[/tex]
=[tex]π×(20)^2[/tex]
=[tex]400π[/tex]
Area of circular field(2)=[tex]πr^2[/tex]
=[tex]π×(48)^2[/tex]
=[tex]2304π[/tex]
The sum of the area of the two fields=[tex]400π+2304π[/tex]=[tex]2704π[/tex]Let the radius of circular field that is formed so be r meter(m).
Now,
[tex] \cancel\pi {r}^{2} = 2704 \cancel\pi[/tex]
[tex] {r}^{2} = 2704[/tex]
[tex]r = \sqrt{2704} [/tex]
[tex]r = 52 \: m[/tex]
Area of the circular field whose area is equal to the areas of two fields,Diameter=[tex]2r[/tex]
Diameter=[tex]2×52[/tex]
Diameter=[tex]104 m[/tex]
The diameter of the circular field whose area is equal to the areas of two fields is 104 m.Step-by-step explanation:

What is the equation for the following graph?
Ans
y=0x+1
Step-by-step explanation:
which of the following polynomials has a graph with odd symmetry? a. 7x^4+13x^3-11 b. 5x^7+4x^6+3x^5+x c.13x^5 -1/2x^3+7x+3 d. 8x^5+7x^3-5x
Answer:
D) [tex]f(x)=8x^5+7x^3-5x[/tex]
Step-by-step explanation:
A function is odd if its graph is symmetric to the origin, which we can check this if [tex]f(-x)=-f(x)[/tex] is true:
Option A
[tex]f(x)=7x^4+13x^3-11\\\\f(-x)=7(-x)^4+13(-x)^3-11\\\\f(-x)=7x^4-13x^3-11[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option B
[tex]f(x)=5x^7+4x^6+3x^5+x\\\\f(-x)=5(-x)^7+4(-x)^6+3(-x)^5+x\\\\f(-x)=-5x^7+4x^6-3x^5+x[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option C
[tex]f(x)=13x^5-\frac{1}{2}x^3+7x+3\\\\f(-x)=13(-x)^5-\frac{1}{2}(-x)^4+7(-x)+3\\ \\f(-x)=-13x^5-\frac{1}{2}x^4-7x+3[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option D
[tex]f(x)=8x^5+7x^3-5x\\\\f(-x)=8(-x)^5+7(-x)^3-5(-x)\\\\f(-x)=-8x^5-7x^3+5x[/tex]
Since [tex]f(-x)=-f(x)[/tex], then the function DOES have odd symmetry. You can also see that the function is odd because every term has an odd exponent.
What is 2 to the 5th power multiplied by 2 to the negative 3rd power??
Answer:
4
Step-by-step explanation:
[tex]2^5 \times 2^{-3}[/tex]
Because the powers have the same base of 2, we can apply the index law:
[tex]a^b \times a^c=a^{b+c}[/tex]
Therefore, [tex]2^5 \times 2^{-3}=2^{5-3}=2^2=4[/tex]
You can use the formula a = to find the batting average a of a batter who has h hits in n times at bat. in If a person has a batting average of 280 and has been at bat 300 times, how many hits does the batter have?
Answer:
Step-by-step explanation:
BA = Number of hits / Times at bat
BA = 280 / 300
BA = 0.933
No one past or present, has ever had that kind of batting average.

Raheel is comparing the cost of two parking garages. Garage A charges a flat fee of $6 per car plus $0.50 per hour. Garage B charges a flat fee of $2 per car plus $1 per hour.
Answer:
$6 + .50x = $2 + $1.00x
4 = .50x
8hr = x, the number of hours when both garages cost the same amount
$6 + .50 x 8 =
$10 would be the cost a both garages after 8 hours
Step-by-step explanation:
#A
Flat fee=6Rate of change=0.5Equation in slope intercept form
y=mx+by=0.5x+6#B
Flat fee=2$Rate of change=1Equation in slope intercept form
y=x+2Now for compare take any no
Let's take 10
For garage A
y=0.5(10)+6=5+6=11$For garage B
y=10+2=12$Hence Garage B is charging more
