Store A sells a box of 8 pencils for $0.89. Store B sells a box of 12 pencils for $1.25. Which store sells the better deal? Tell the unit rate for each store (rounding to nearest cent)
Answer:
Should be store B :) The unit rate for store A (rounded) is 0.11 and the rounded unit rate for store B is 0.10
Step-by-step explanation:
Answer:
Store B has the better deal
Unit rate:
Store A = $0.11
Store B = $0.10
Step-by-step explanation:
Store A :
8pencils = $0.89
1 pencil = $0.89/8 = $0.111
Store B:
12pencils = $1.25
1 pencil = $1.25/12 = $0.104
Store B sells 1 pencil at $0.104 and store A at $0.111
Therefore Store B sells the better deal.

In a softball game, how far must the catcher throw to second base? Round to the
nearest tenth.
84.9 ft
42.4 ft
0 120 ft
60.8 ft
Answer:
84.9 ft
Step-by-step explanation:
a^2 + b^2 = c^2
60^2 + 60^2 = c^2
3600 + 3600 = 7200
the square root of 7200
84.8528137424 ft or 84.9 ft
If two cylinders have the same base, and one cylinder has a height of 4 inches and a volume of 120 cubic inches, and the second cyclinder has 7 inches what's the volume of the second cylinder
Answer:
210 cubic inches
Step-by-step explanation:
The volume V of a cylinder is given as
V = πr^2h where r is the base radius and h is the height
If two cylinders have the same base, then their radii are the same
Given that one cylinder has a height of 4 inches and a volume of 120 cubic inches then
120 = πr^2 * 4
Divide both sides by 4
30 = πr^2
Given that the second cylinder has a height of 7 inches then the volume
V = πr^2 * 7
Recall that 30 = πr^2
V = 30* 7
= 210 cubic inches

Answer:
t= 41.2 minutes
Step-by-step explanation:
[tex]16=290(0.5)^{\frac{t}{10} }[/tex]
Divide by 290 to get the exponential expression alone
[tex]\frac{16}{290} \\\frac{8}{145}=(.0.5)^{t/10}[/tex]
Use Logs to solve
[tex]x=a^{y}[/tex] is equal to [tex]y=log_{a} x[/tex]
[tex]\frac{t}{10} =log_{0.5} \frac{8}{145}[/tex] (put in calculator)

Mr.Eastman drew triangle JKL,with a height of 12 inches and a base of 12 inches, and triangle XLZ, with a height of 8 inches and a base of 16 inches.Which trangle has the greater area?
Answer:
Step-by-step explanation:
Area of triangle = 1/2 × Base × Height
Mr.Eastman drew triangle JKL,with a height of 12 inches and a base of 12 inches
Area of JKL = 1/2 × 12 inches × 12 inches
= 72 Square inches

Lamar needs to buy some pencils. Brand A has a pack of 18 pencils for 2.36 . Brand B has a pack of pencils 24 for 4.09 Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.
Answer:
The unit price of brant A and brand B is 0.1311 and 0.1704 and brand A would be better
Step-by-step explanation:
The computation of the unit price for each brand is shown below:
For brand A, the unit price is
= 2.36 ÷ 18 pencils
= 0.1311
For Brand b, the unit price is
= 4.09 ÷ 24
= 0.1704
So here as we can see that brand A would be better as it has less cost as compared with brand B

HELP ONLY ANSWER IF YOU ARE 100% RIGHT. HAVE BEEN WORKING ON THIS FOR ALMOST 11 HOURS. SHOW WORK PLEASE!!!!!! NO LINKS!!!!
Answer:
180 ft2
Step-by-step explanation:
First solve for the area of the trapzeoid using formula:
A= a+b/2xh
10+18x6/2
A= 84 ft2
Then solve for the rectangles B and C:
12x4= 48
48x2 (because theres two rectangles) which equals 96
Combine the two to get the total area:
96+84= 180

Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 24 units to the right of the vertex of the graph of g(x). Which pair of functions could have been used to create the graphs of g(x) and h(x)?
h(x)=x2−24 and g(x)=x2
h(x)=x2+24 and g(x)=x2
h(x)=(x−24)2 and g(x)=x2
h(x)=(x+24)2 and g(x)=x2
Answer:
The correct pair of functions is the third one: h(x)=(x−24)^2 and g(x)=x2
Step-by-step explanation:
Example: If we have q(x) = x^2 and its graph, moving the vertex of this graph 24 units to the right results in r(x) = (x - 24)^2.
The correct pair of functions is the third one: h(x)=(x−24)^2 and g(x)=x2
Note: the fourth pair is incorrect, because the " + " sign moves the graph of x^2 24 units to the left.
Answer:
C)h(x)=(x−24)2 and g(x)=x2
