Leah needs to order some new supplies for the restaurant where she works. The restaurant needs at least 748 knives. There are currently 214 knives. If each set on sale contains 12 knives, write and solve an inequality which can be used to determine ss, the number of sets of knives Leah could buy for the restaurant to have enough knives.
Answer: s (greater than or equal to) 44.5
Step-by-step explanation:
current # of knives = 214
knives per set = 12
knives needed = 748
# of sets = s
knives per set x (times) # of sets + current # of knives (greater than or equal to) knives needed
12s + 214 (greater than or equal to) 748
SOLVE:
12s + 214 (greater than or equal to) 748
-214 -214
12s (greater than or equal to) 534 you need to divide both sides by 12
s (greater than or equal to) 44.5
Scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. Certificates are given to students whose scores are in the top 2% of those who took the test. This means that they scored better than 98% of the other test takers. Marcus received his score of 13.7 on the exam and is wondering why he didn’t receive a certificate. Show all work to determine whether Marcus’ score was high enough to earn a certificate. Write a letter to Marcus explaining whether or not he will be receiving a certificate. Include a brief summary of your statistical analysis in your letter.
Answer:
Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.

If the principal is $4,500 and the rate of interest is 8%, what is the amount of interest after one year? Formula is I =PRT
Step-by-step explanation:
I=?
P= $4500
R=8%=0.08
T=1 year
8%*0.01= 0.08
I=(4500)(0.08)(1)
(4500)(0.08)=360
360*1=360
The interest after one year is $360

For each question order the cards from least to greatest. If the feature is equal to two or more functions, place them next to each other. y-coordinate of the y-intercept
(the letters/cards need to be put in order form least to greatest based on y-coordinate of the y-intercept)
Answer:
C, D (-4) ⇒ E, G (0) ⇒ H (1) ⇒ A, F (3) ⇒ B(8)Step-by-step explanation:
The y-intercept is the coordinate of y at x = 0.
Let's find them all and then order.
A)
a(0) = -2*0 + 3 = 3B)
b(0) = 8 as per graphC)
c(0) = - 4 as per graphD)
d(0) = 0² - 4 = - 4E)
The point to be found after the equation of the function e(x)
We can see it is a linear function as the rate of change is constant
Use two points from the table (-1, 2) and (1, -2), find the slope:
m = (-2 - 2)/(1 - (-1)) = -4/2 = -2Use one point to find the y-intercept:
y - 2 = -2(x - (-1))y - 2 = -2x - 2y = -2x e(x) = -2xe(0) = 0F)
f(0) = 3 as per graphG)
g(0) = 2(3⁰) - 2 = 2 - 2 = 0H)
h(0) = 1 as per tableTwo cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the northbound car has traveled 4 kilometers, and the eastbound car has traveled 3 kilometers. Measured in a straight line, how far apart are the two cars?
Answer:
The distance between them is 5km
Step-by-step explanation:
Given
[tex]Car\ A =4km[/tex]
[tex]Car\ B =3km[/tex]
Required
Distance between them
The scenario can be represented with the attached image
The distance between them is then calculated using Pythagoras theorem
[tex]d^2 = 4^2 +3^2[/tex]
[tex]d^2 = 16 +9[/tex]
[tex]d^2 = 25[/tex]
Take square roots of both sides
[tex]d = \sqrt{25[/tex]
[tex]d = 5[/tex]

What is the solution of the equation?
-1 =V
-
3
Answer:
I think you mean "-1=v-3" which if that is the case the answer is V=4
Step-by-step explanation:
To know what is V.... you got to make remove the -3 and transfer it to the other side, which will change its' sign so it will be +3
the new equation: +3-1 = V
the answer: 2 = v
Meaning that V is 2,

The length of 12cm and 5 cm missing one
Answer:
13cm
Step-by-step explanation:
Let the given lengths be the opposte amd adjacent sides of a right triangle'
The missing side will be the hypotenuse
Using the pythagoras theorem;
hyp^2 = 5² + 12²
hyp² = 25 + 144
hyp² = 169
hyp =√169
hyp = 13cm
Hence the missing one is 13cm

____________________Solution :-Given Information :-Fraction 1 ➢ [tex] \sf12 \frac{1}{2} [/tex]Fraction 2 ➢ [tex] \sf -4 \frac{1}{2} [/tex]Operation ➢ Subtraction To Find :-The difference between two fractionsCalculation :-[tex] \sf: \implies \sf12 \frac{1}{2} - ( - 4 \frac{1}{2} ) = \boxed{ ? }[/tex]
Firstly, converting mixed fractions to improper fractions, We get,
[tex] \sf: \implies \frac{25}{2} - ( - \frac{9}{2} ) = \boxed?[/tex]
Now, solving the parentheses, We get,
[tex] \sf: \implies \frac{25}{2} + \frac{9}{2} = \boxed ?[/tex]
Since, We have like terms, We will directly add up the two fractions, We get,
[tex] \sf: \implies \frac{25 + 9}{2} = \boxed?[/tex]
Calculating further, We get,
[tex] \sf: \implies \frac{34}{2} = \boxed?[/tex]
Bringing the fraction to it's lowest terms, We get,
[tex] \sf: \implies \frac{ \cancel{34} \: \: \tiny{7}}{ \cancel2} = \boxed7[/tex]

5/8+3/4 over this problem(/) -2/3-5/6.
Answer:
5/8 + 3/4= 11/8
-2/3-5/6 =-3/2
Since the second is dividing the first
11/8 ÷ -3/2
Flipping; Then change the bottom to the top(Do this to the second fraction)
11/8 x -2/3
=-11/12.

169.646003294, hope this helps
Step-by-step explanation:
To solve this equation,
A= [tex]2\pi rh+2\pi r^{2}[/tex]
Since the radius is 3 meters. We know what r is. A radius of a circle or sphere is any of the line segments from its center to the perimeter. The height is 6 meters.
[tex]A=2\pi (3)*6+2\pi (3^2)\\ A=2\pi (18)+2\pi 9\\ A=113.097...+2\pi 9\\ A=113.097+56.548...\\ A=169.64600...[/tex]

Applying the 45-45-90 Theorem, Find the lengths of the other two sides of a right triangle if the length of the hypotenuse is 4√2 inches and one of the angles is 45°.
Rule: If x is the leg of a 45-45-90 triangle, then x*sqrt(2) is the hypotenuse.
We can prove this by showing that x^2+x^2 = (x*sqrt(2))^2 is an identity. It's from the pythagorean theorem a^2+b^2 = c^2.
Put another way, if we know that a = x and b = x are the two congruent legs, then x^2+x^2 = c^2 leads to c = x*sqrt(2). This triangle is known as an isosceles right triangle.
So if 4*sqrt(2) is the hypotenuse, we match that up with the template x*sqrt(2) and see that x = 4 must be the case.
