Answer: 5. The second box required more material to make.
6. A company saves about $84.94 by choosing to make fifty boxes of the smaller box in comparison to fifty boxes of the larger box.
Step-by-step explanation:
5. To solve this problem you need to find the volume of the boxes.
Volume of the first box.
v= 8 * 6.25 * 10.5
v= 525
Second box volume
9 * 5.5 * 11.75 = 581.625
Which means the second box required more material to make because it has the greatest volume.
6. To solve this you have to multiply the volume of small and large boxes by 50 the multiply it by 0.03.
525 * 50 = 26250 * 0.03 = 785.5
581.625 *50 = 29081.25 * 0.03= 872.4375
872.4375 - 785.5 = 84.9375 which is about $84.94.

G/2 + 7 = 21
Can I get help with this??
Answer:
g = 28
Step-by-step explanation:
g/2 + 7 = 21
Subtract 7 on both sides.
g/2 = 21-7
g/2 = 14
Multiply 2 on both sides.
g = 2(14)
g = 28
Answer:
g=28Solution,
[tex] \frac{g}{2} + 7 = 21 \\ or \: \frac{g + 7 \times 2}{2} = 21 \\ or \: \frac{g + 14}{2} = 21 \\ or \: g + 14 = 42(cross \: multiplication) \\ or \: g = 42 - 14 \\ g = 28[/tex]

Step-by-step explanation:
I have attached the work to your problem.
Please see the attachment below.
I hope this helps!
Answer:
4. 121800
5. 591.09375
6. 0.25
Step-by-step explanation:
4. It's an AP with:
first term(a): 12
common difference(d): 24-18 = 6
Sn = (n/2)(2a + (n-1)d)
S200 = (200/2)[2(12) + (200-1)(6)]
= 121800
5. It's an GP with:
first term(a): 12
common ratio(r): 18/12 = 1.5
Sn= a(r^n -1)/(r-1)
S8 = 12(1.5⁸-1)/(1.5-1)
= 18925/32 = 591.09375
6. It's an infinite GP with:
first term(a) = 1/12
common ratio: 1/18 ÷ 1/12 = ⅔
Sinfinity: a/(1-r)
= (1/12) ÷ [1-⅔]
= 1/12 ÷ 1/3
= 1/12 × 3
= 1/4 = 0.25

F(x) = x^2-3x+18f(x)=x 2 −3x+18f, left parenthesis, x, right parenthesis, equals, x, squared, minus, 3, x, plus, 18 What is the value of the discriminant of fff? How many distinct real number zeros does fff have?
Answer:
No real roots or no real zeros.
Step-by-step explanation:
The given function is
[tex]f(x)=x^2-3x+18[/tex]
We need to find the number of real zeroes.
The given function is a quadratic function.
Let a quadratic function is [tex]f(x)=ax^2+bx+c[/tex].
If [tex]b^2-4ac<0[/tex], then the function has no real root.
If [tex]b^2-4ac=0[/tex], then the function has one real root with multiplicity 2.
If [tex]b^2-4ac>0[/tex], then the function has two real roots.
In the given function,
[tex]a=1,b=-3,c=18[/tex]
So,
[tex]b^2-4ac=(-3)^2-4(1)(18)=9-72=-63<0[/tex]
The value of discriminant is -63.
Therefore, the given function has no real root or no real zeros.
Answer:
The discriminant value of F is -63
F has 0 distinct real number zeros

The Happy-Go-Lucky Beach was 163 feet long from parking lot to high tide. After last year's hurricane came ashore, the beach only measured 154 feet
long. What was the percent of change?
About 94.5% of increase
About 94.5 % of decrease
About 5.5% increase
About 5.5% decrease
Answer:
About 5.5% decrease
Step-by-step explanation:
Here, we want to calculate the percentage increase or decrease and its value.
The first thing to do here is to check if we are going to have a decrease or an increase.
since the value before the change is higher than the value after the change, then what we have is a decrease.
Mathematically, the percentage decrease is calculated as follows;
% decrease = (old value - new value)/old value * 100%
old value = 163 feet
new value = 154 feet
% decrease = (154-163)/163 * 100%
% decrease = -9/163 * 100%
% decrease = -5.52%
Thus the best answer is about 5.5% decrease

There are two numbers whose sum is 47. Three times the smaller number is equal to 9 more than the larger number. What are the numbers?
answer.
14 and 33
Step-by-step explanation:
lets use x for the smaller number and y for the other
x+y=47
3x=y+9
x=47-y
3(47-y)=y+9
141-3y=y+9
put the liketerms together
141-9=3y+y
132=4y. (divide both sides by 4)
y=33
x=14
Answer:
14&33
Step-by-step explanation:
x+y=47
3x=y+9
x=47-y
3(47-y)=y+9
141-3y=y+9
141-9=3y+y
132=4y
y=33

Solve the following equation:
2/3 - 1/x = 13/15
Answer:
x=−5
Step-by-step explanation:
Steps:
Step 1 to 4 : Simplify
Steps 5: Calculating the Least Common Multiple
Steps 6: Calculating Multipliers
The correct answer for this question is x=−5
Answer: x=−5
Hope this helps.
Answer:
x = -5
Step-by-step explanation:
2/3 - 1/x = 13/15
Subtract 2/3 from each side
2/3 -2/3 - 1/x = 13/15 -2/3
-1/x = 13/15 - 2/3
Getting a common denominator
-1/x = 13/15 -2/3*5/5
-1/x = 13/15 - 10/15
-1/x = 3/15
Using cross products
3x = -15
Divide each side by 3
3x/3 = -15/3
x = -5

Samantha and Jillian were going for a walk. Jillian left 15 seconds ahead of Samantha. • Samantha walked at a speed of 7 feet per second. • Jillian walked at a speed of 6 feet per second. How many seconds had Jillian been walking when the two girls had walked the same distance?
Is the answer 105?
Answer:
105 seconds
Step-by-step explanation:
To solve this, we can set up an equation.
First, let's find how far ahead Jillian is.
15*6=90
Jillian is 90 feet ahead.
Let's name the time that Samantha walks x.
7x is the distance Samantha walks.
90+6x is the distance Jillian walks.
We want to find how many seconds they have walked when the distance is equal.
So let's form an equation.
7x=90+6x
Subtract 6x from both sides.
x=90
Samantha needs to walk 90 seconds.
Jillian started 15 seconds before that.
90+15=105
Jillian had been walking for 105 seconds when the two girls had walked the same distance.

find the coordinate of K' after a Glide reflection of the triangle: translation 4 units up and 4 units right then a reflection across the line y = 1.
Part 3a
Answer:
a. (-1, 3)
Step-by-step explanation:
The "glide" 4 units right and up is the transformation ...
(x, y) ⇒ (x+4, y+4)
The reflection across y=1 is the transformation ...
(x, y) ⇒ (x, 2-y)
Combined, you have the transformation ...
(x, y) ⇒ (x +4, 2-(y +4)) = (x +4, -2-y)
Then, ...
K(-5, -5) ⇒ K'(-5 +4, -2-(-5)) = K'(-1, 3)

What is the value of \cos(\theta_1)cos(θ 1 )cosine, (, theta, start subscript, 1, end subscript, )?
Answer:
[tex]\cos(\theta_1)=-\dfrac{\sqrt{15}}{4}[/tex]
Step-by-step explanation:
The angle [tex]\theta_1[/tex] is located in Quadrant II.
[tex]\sin(\theta_1)=\dfrac{1}{4}[/tex]
From trigonometry, we know that:
[tex]\sin(\theta)=\dfrac{Opposite}{Hypotenuse}\\$Therefore:\\Opposite=1\\Hypotenuse=4\\Using Pythagorean theorem:\\Hypotenuse^2=Opposite^2+Adjacent^2\\4^2=1^2+Adjacent^2\\Adjacent^2=16-1\\Adjacent^2=15\\Adjacent=\sqrt{15}[/tex]
Now, in Quadrant II,
The x-axis is negativeThe y-axis is positiveTherefore, the Adjacent angle to [tex]\theta_1 =-\sqrt{15}[/tex]
Therefore:
[tex]\cos(\theta_1)=\dfrac{Adjacent}{Hypotenuse}=\dfrac{-\sqrt{15}}{4}\\\\\cos(\theta_1)=-\dfrac{\sqrt{15}}{4}[/tex]
Lucy’s parents built a swimming pool in the backyard. that the width is 18ft and the length is30ft , what's the disentrance around the pool , and what's the area of the pool , Use 3.14 for π.
Answer:
P=96;A=540
Step-by-step explanation:
To find the perimeter, the distance around the pool, all you need to do is add 18+18 then add 30+30. Why? Because assuming the pool is a rectangle, it would have 4 sides. The two width sizes as 18 and the two lengths as 30. Now, finding the area is even simpler. All you have to do is multiply the width by the length. 18*30.

Richard drives his car for 5 hours.
His average speed is 30 mph.
(a) How far does Richard travel?
miles
Richard drives 560 km the next day.
(b) Work out how much further Richard travelled, compared to the previous day.
5 miles = 8 kilometers
miles
Answer:
A. 150 miles
B. 200 miles further
Step-by-step explanation:
Multiply 30 by 5 to find how far he traveled the first day
30 x 5 = 150 miles
For the second day, convert km to miles by making a proportion
[tex]\frac{5}{8}[/tex] = [tex]\frac{x}{560}[/tex]
x = 350 miles
Then, to find the difference, subtract the 350 - 150 = 200

If 32 % of a is 1.12 then what is the value of a?
Answer:
4.5 is the value of A
Step-by-step explanation:
do it doing part/whole and cross crossing :)
32/100 because it’s a percentage and 1.12/x. 1.12 times 100 to get 112, and then 32 times x = 32x. your equation right now is 32x = 112, bur we want to get rid of that x, so we are going to divide 112/32 to get the whole of 3.5 for the value of A.
