9. Jacob ordered 4 pizzas to be delivered
.
Each pizza costs $12.75.
Jacob gave the driver an 58 tip when the pizzas were delivered
Which of the following expressions could be used to determine Jacob's total cost?
O A 4(12.75 + 8)
OB. 4 (12.75) +8
OC. 4 (8) + 12.75
OD. 4 (12.75 - 8)
Answer:
A
Step-by-step explanation:
i think because it would equal to a logical number and estimation for the total cost (total for that sum is 83)
What is the inverse of y= 3/2x -2
Answer:
f^-1(x) = (2x + 4) / 3
Step-by-step explanation:
- switch 'y' with 'x'
x = 3/2y - 2
- solve for 'y'
x + 2 = 3/2y
- multiply each side by 2
y = (2x + 4) / 3

The new video game that Greg wants to purchase is sold for $40 at Techno Hut and for $45 at Gamer World. If Greg has a 10% off coupon for all purchases at Techno Hut and a 15% off coupon for video games at Gamer World, which statement is true? A. After coupons, the game is the same price at both stores. B. After coupons, the game is $5.50 cheaper at Techno Hut. C. After coupons, the game is $2.75 cheaper at Gamer World. D. After coupons, the game is $2.25 cheaper at
Hey there!
The answer to your question is D.) After coupons, the game is $2.25 cheaper at Techno Hut
First, we will solve for the price of Techno Hut's game. Let's find the amount of the discount:
0.10 x 40
4
Then, we take the discount off the price:
40 - 4 = 36
The price of the game at Techno Hut is $36
Next, we find the price of the game at Gamer World. Let's find the amount of the discount:
0.15 x 45
6.75
Then, we take the discount off the price:
45 - 6.75 = 38.25
The price of the game at Gamer World is 38.25
Therefore, Techno Hut is cheaper.
Hope it helps! Good luck and have a great day!

1)find the GCF
2)factor out the GCF
3)what are the solutions?
X1= and x2=
Answer:
10+10=20 +10=30
Answer:
GCF=X
FACTOR OUT X(5X+2)=0
X1=0 AND X2=-2/5
Step-by-step explanation:
The GCF is x . So when we factor it out we get
GCF =x
Factor out x (5x+2)=0
x1=0 and x2=-2/5

A probability is a number between 0 and 1 that reflects the likelihood of some outcome. According to the classical approach to assigning probability, the probability that an outcome occurs is interpreted as:
Answer:
Probability of an event [tex]=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex]
Step-by-step explanation:
According to the classical approach to assigning probability, if an experiment has [tex]n[/tex] simple outcomes, this method would assign a probability of [tex]\frac{1}{n}[/tex] to each outcome. In other words, each outcome is assumed to have an equal probability of occurrence.
So, probability of an event [tex]=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex]

List of sides in order from shortest to longest 
Answer:
x = 12
m∠A = 104º
m∠B = 32º
m∠C = 44º
shortest side = B
middle side = C
longest side = A
Step-by-step explanation:
Recall that all angles in a triangle add up to 180º. Also recall that the side opposite largest angle is the longest side, and vice versa for the side opposite the smallest angle.

Answer:
The value of x is -2 and 2.
Step-by-step explanation:
When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :
x² - 3x - 1 = -3x + 3
x² - 3x - 1 + 3x - 3 = 0
x² - 4 = 0
Next, you have to factorize and solve it :
x² - 4 = 0
x² + 2x - 2x - 4 = 0
x(x + 2) - 2(x + 2) = 0
(x + 2)(x - 2) = 0
x + 2 = 0
x = -2
x - 2 = 0
x = 2

One of the students is chosen at random. What is the probability that this student is wearing a watch or a braclet
Complete question :
At a certain school, 25% of the students wear a watch and 30% wear a bracelet. 60% of the students wear neither a watch nor a bracelet.
a) One of the students is chosen at random. What is the probability that this student is wearing a watch or a bracelet?
b) What is the probability that this student is wearing both a watch and a bracelet?
Answer:
0.40 ; 0.15
Step-by-step explanation:
Let :
w = watch
b = bracelet
P(W) = 0.25
P(B) = 0.3
P(either a watch or a bracelet) = P(WuB)
P(neither a watch nor a bracelet) = 1 - P(WuB)
1 - P(WuB) = 0.6
a.) probability that student is wearing a watch or a bracelet = P(WuB)
P(neither a watch nor a bracelet) = 1 - P(WuB)
0.6 = 1 - P(WnB)
P(WnB) = 1 - 0.6
P(WnB) = 0.4
B.) probability that student is wearing both a watch and a bracelet : P(WnB)
Using the probability relation :
P(WuB) = P(W) + P(B) - P(WnB)
0.4 = 0.25 + 0.30 - P(WnB)
0.4 = 0.55 - P(WnB)
P(WnB) = 0.55 - 0.40
P(WnB) = 0.15
Write the following equation symbolically.
The sum of h and 5 is equal to 8 less than 6 times y.
Answer:
h+5=(6y)-8
Step-by-step explanation:
The sum is addition. So it wants you to add h and 5 on one side. Do 6 and y in parentheses on the other side and it wants you to subtract 8 from what you got from 6 times y.

what is the answer to 5+5(9b - 7)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
5+5(9b - 7)
FIRST CASE (JUST EVALUATION)
Given the expression
[tex]5+5\left(9b-7\right)[/tex]
[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac[/tex]
[tex]5+5\left(9b-7\right)=5+5\cdot \:9b-5\cdot \:7[/tex]
[tex]=5+45b-35[/tex]
[tex]= 45b - 30[/tex]
Therefore, we conclude that:
[tex]5+5\left(9b-7\right)=45b-30[/tex]
SECOND CASE (Finding the value of b)
Assuming we have to determine the value of b
[tex]5+5(9b - 7) = 0[/tex]
As we have determined
[tex]5+5\left(9b-7\right)=45b-30[/tex]
so substituting [tex]5+5\left(9b-7\right)=45b-30[/tex] in the equation
[tex]45b-30 = 0[/tex]
Add 30 to both sides
[tex]45b-30+30=0+30[/tex]
Simplify
[tex]45b=30[/tex]
Divide both sides by 45
[tex]\frac{45b}{45}=\frac{30}{45}[/tex]
Simplify
[tex]b=\frac{2}{3}[/tex]
Therefore, the value of b = 2/3
Find an equation of the plane consisting of all points that are equidistant from (-1, 1, -5) and (4, -5, 0).
Answer: the required equation is 5x - 6y + 5z = 7
Step-by-step explanation:
Given that;
points : (-1, 1, -5) and (4, -5, 0).
mid point : ( [(-1+4)/2], [(1-5)/2], [(-5+0)/2]
⇒ midpoint : ( 3/2, -2, -5/2 )
x₀ y₀ z₀
Direction vector n = [4-(-1)], [ -5 - 1], [ 0 - (-5)]
⇒ Direction vector n = < 5, -6, 5 >
General equation plane : n(x-x₀, y-y₀, z-z₀) = 0
so we substitute
⇒ (5, -6, 5) (x-3/2, y-(-2), z-(-5/2) ) = 0
⇒ (5, -6, 5) (x - 3/2, y + 2, z + 5/2) ) = 0
⇒ 5(x - 3/2) - 6(y + 2 ) + 5(z + 5/2) = 0
⇒ 5x - 15/2 - 6y - 12 + 5z + 25/2 = 0
⇒ 5x - 6y + 5z = 15/2 + 12 - 25/2
⇒ 5x - 6y + 5z = 7
Therefore, the required equation is 5x - 6y + 5z = 7
which is an equation of the line graphed below
A sample of 14001400 computer chips revealed that 311% of the chips do not fail in the first 10001000 hours of their use. The company's promotional literature claimed that more than 28(% do not fail in the first 10001000 hours of their use. Is there sufficient evidence at the 0.050.05 level to support the company's claim
Answer:
There is sufficient evidence at 0.05 significant level to support company's claim.
Step-by-step explanation:
We have these informations from the question
n = 1400
P^ = 31% = 0.31
Alpha level = 5% = 0.05
Then we come up with the hypothesis
H0: P = 0.28
H1: P>0.28
From here we calculate the test statistic
z = p^ - p/√pq/n
P = 0.28
q = 1-0.28
= 0.72
z = 0.31-0.28/√(0.31*0.72)/1400
= 0.03/√0.0001594
= 0.03/0.012
= 2.5
Then we have a p value = 0.00621
The p value is less than significance level
0.00621<0.05
So the null hypothesis is rejected.
We conclude that There is sufficient evidence at 0.05 significant level to support company's claim.
