29 candy bars
Step-by-step explanation:
13 movie pases= $9.50x13= $123.50
3 gift cards= $25×3 =$75
amount of money she has left over to buy candy bars = $250- $75- $123.5 = $51.50
Amount of candy bars she can buy = $51.50÷$1.75 = 29.43 candy bars, but u can only buy full candy bars and there for 29 candy bars is the final answer
Upon review of production results, it was determined that 130 pieces out of 3,500 were "out of spec." What percent of the production was "out of spec"?
A. 0.03 percent .
B. 3.71 percent .
C. 30 percent
D. 37.1 percent
Answers
Answer:
Option B
Step-by-step explanation:
Given:
130 pieces of 3500 were out of specTo determine the percentage of the production was out of spec, we need to use the percentage formula (x/y × 100).
[tex]\implies \dfrac{x}{y} \times 100[/tex]
The value of "x" is the the number of pieces that were out of spec and the value of "y" is the total pieces in the production results.
[tex]\implies \dfrac{130}{3500} \times 100[/tex]
Simplify the expression to determine the percentage of the pieces that were out of spec.
[tex]\implies \dfrac{13000}{3500}[/tex]
[tex]\implies \dfrac{130}{35} = \dfrac{130 \div 5}{35 \div 5} = \dfrac{26}{7} = 3.714... \%[/tex]
When the percentage is estimated to nearest hundredth, we get 3.71%
(Option B)
Answer:
B) 3.71%
Step-by-step explanation:
[tex]\textsf{130 out of 3500}\sf =\dfrac{130}{3500}[/tex]
To convert to a percentage, multiply by 100:
[tex]\implies \sf \dfrac{130}{3500} \times 100\%=0.03714.. \times 100\%=3.71\%[/tex]
What number increased by ¼ of itself is equal to 30?
Answers
Answer:
x = 24
Step-by-step explanation:
let x be the number we want to determine its value
The statement x increased by ¼ of itself is equal to 30
is equivalent to :
[tex]x + \frac{x}{4}=30\\\\then[/tex]
[tex]\frac{4x+x}{4} = 30\\\\then[/tex]
[tex]\frac{5x}{4} = 30\\\\then[/tex]
5x = 4× 30
then
5x = 120
then
x = 120/5
then
x = 24

color. Which statement is not true?
Answers
Answer:
C. The likelihood of having brown eyes is 35%
Step-by-step explanation:
Add the total number of people, which gives you 50.
To find the percent of brown-eyed people out of 50, divide 35 by 50, then multiply the result (0.7) by 100 to get 70%.
70% of people are brown-eyed, thus, C is a false statement.
Answer:
the answer is C
Step-by-step explanation:
the brown eyes would be 70 percent actually

Find the area of the shaded region. Round to the nearest hundredth where necessary. Hint: Could you find the radius?
Answers
Answer:
13.72 cm²
Step-by-step explanation:
The formula to find the area of a shaded region: Area of the bigger shape - area of the smaller shape.
The formula to find the area of a square: [tex]a^{2}[/tex], where [tex]a[/tex] is the side.
The formula to find the area of a circle: [tex]\pi r^{2}[/tex], where [tex]\pi[/tex] is 3.14 or [tex]\frac{22}{7}[/tex] or 3.142 or similar, [tex]r[/tex] is the radius (diameter ÷ 2).
1) Find the area of the circle using the formula. The radius is 4 because the diameter is 8 (8 ÷ 2 = 4).
= [tex]\frac{22}{7}*4^{2}[/tex]
= [tex]\frac{22}{7}*16[/tex]
= 50.285
2) Find the area of the square using the formula.
= [tex]8^{2}[/tex]
= 64
3) Apply: area of the bigger shape - area of the smaller shape.
= 64 - 50.285
= 13.715
4) Round it off to the nearest hundredth.
= 13.72

Which function is equivalent to g(x)= x2 +11x-60?
Answers
g(x) = x^2 + 11x - 60
(a=1, b=11, c=-60)
To solve this quadratic equation we need to find the discriminant:
discriminant= b^2 - 4ac
= (11)^2 - 4(1)(-60)
=121 - (-240) = 121+240 =361
(if discriminant<0 then equation has no real root
if discriminant=0 then equation has 1 real root
if discriminant>0 then equation has 2 real roots)
Here we have discriminant=361>0 so we have 2 real roots:
x1=(-b-redical discriminant) / 2a
and x2=(-b+redical discriminant) / 2a
x1= (-11-redical(361)) / 2(1)
=-15
x2= (-11+redical(361)) / 2(1)
=4
So we get the two roots x= -15 and x= 4
To write the quation in factorized form:
x= -15 means that x+15=0
x= 4 means that x-4=0
Therefore g(x)= (x+15)(x-4)
D is the correct answer

60 point help What are domain restrictions of rational functions? What do domain restrictions mean for the graph of a rational function?
Answers
Answer:
1. The use of a domain for a function that is smaller than the function's domain of definition. Note: Restricted domains are commonly used to specify a one-to-one section of a function.
2. Domain restrictions can be calculated by finding singularities, which are the x -values for which the denominator Q(x) is zero.
Answer:
by setting the denominator equal to zero and solving. The x -values at which the denominator equals zero are called singularities and are not in the domain of the function.
