92 boxes
1379/15=91.93 but u need a full box so 92
Answer:
92
Step-by-step explanation:
Given:
Number of Paperweights = 1,379
Number of Paperweights that each box can hold = 15
Number of boxes needed = 1379 ÷ 15 = 91.933 boxes
Because 0.933 of a box is of no use to anyone, we simply round this number up to the next whole box and just have the last box partially full.
This gives us 92 boxes.
plz help which expression is equivalent to 4-2/2^-3
8
16
-8
-16
Answer:
The answer is 16.
Step-by-step explanation:
In this expression 4-2/2^-3, first of all we will solve the numerator.
Subtract 4 and 2
4-2= 2
So, the expression will become 2/2^-3
Now notice that the numerator has the base 2 and exponent 1 where as the denominator has the base 2 and exponent -3. Both the numerator and denominator have the same base
So we will use the property a^m/a^n=a^m-n.
=2/2^-3
=2^1-(-3)
=2^1+3
=2^4
2^4 means that 2 will be multiplied 4 times.
=2*2*2*2
=16
Thus the answer is 16....
Find the area of the shaded region in the polygon below.
Answer:
35
Step-by-step explanation:
I multiply 3 and 7 that give 35
Answer:
Step-by-step explanation:
The area of a pentagon given the radius is
Area = (5/2)r^2 * sin(72º)
r = 7
Area = (5/2)*7^2 * sin(72)
Area = 122.5 * 0.95106
Area = 116.5
=============
r = 5
Area = (5/2) * 5^2 * sin(72)
Area = 59.4
Area of the shaded area = 116.5 - 59.4
Area of the shaded area = 57.1
Which is the graph of x ≤ 2? Graph of a dashed vertical line 2 units to the right of the origin with everything shaded to the right. Graph of a solid vertical line 2 units to the right of the origin with everything shaded to the right. Graph of a dashed vertical line 2 units to the right of the origin with everything shaded to the left. Graph of a solid vertical line 2 units to the right of the origin with everything shaded to the left.
Answer:
Graph of a solid vertical line 2 units to the right of the origin with everything shaded to the left.
Step-by-step explanation:
The solid line shows it is greater than or equal to. Shade to left of vertical line if less than and right of it if greater than.
Answer:
A graph of a solid vertical line 2 units to the right of the origin with everything shaded to the right.
Step-by-step explanation:
The inequality x≤ 2 means that for any coordinate picked to the left of the line x=2 including 2 satisfies the argument for x. The less than or equal to sign means the value of x is 2 or less.
If for example you pick (2,5) or even (-1,150), the x coordinate satisfies the inequality.
If f(x) = 27 +3 and g(x) = x - 7, find (f - g)(x).
Answer:
(f - g)(x) = 37 - x
Step-by-step explanation:
(f - g)(x) = (27 +3) - (x - 7)
= 27 + 3 - x + 7
= 37 - x
Answer:
(f - g)(x) = 26x + 10Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
We have f(x) = 27x + 3 and g(x) = x - 7. Substitute:
(f - g)(x) = (27x + 3) - (x - 7)
(f - g)(x) = 27x + 3 - x - (-7)
(f - g)(x) = 27x + 3 - x + 7 combine like terms
(f - g)(x) = (27x - x) + (3 + 7)
(f - g)(x) = 26x + 10
Jack is driving from his house to the airport. At 9:00 AM, he is 150 miles from the airport. At 10:30 AM, he is 75 miles from the airport. What is Jack’s average driving speed between 9:00 AM and 10:30 AM?
______ miles/hour
Answer:
I b3live it is 50 miles/hour
Step-by-step explanation:
We need to know how many miles he drove from 9:00 to 10:30 so you do 150-75 which is 75. Then, you do 75÷1.5 because 9:00 and 10:30 are an hour and a half apart and then you get 50 mph.

Can the set of lengths be the side lengths of a right triangle?
7ft, 12ft, 17 ft
Answer:
No
Step-by-step explanation:
For a right triangle, a^2+b^2=c^2 EVERY time.
a and b are always smaller than c, so 7 and 12 are a and b, and 17 is c:
7^2+12^2 ?= 17^2
49+144 ?= 289
193 != 289
Therefore, these can't be the set of lengths for a right triangle
Answer:
These set of lengths cannot be the side lengths of a right angled triangle.
Step-by-step explanation:
Pythagoras Theorem is always followed by a right angled triangle. According to which the sum of squares of the two shorter legs is equal to the square of the longest leg.
[tex]a^2=b^2+c^2[/tex]
So here, 17 is the longest leg and 7 and 12 the shorter ones.
Applying Pythagoras Theorem to these lengths to find out.
[tex]17^2=7^2+12^2[/tex]
[tex]289\neq 193[/tex]
Therefore, these set of lengths cannot be the side lengths of a right angled triangle.

How to rationalize the denominator of sqrt(a)/sqrt(a)-2
Step-by-step explanation:
√a / (√a - 2)
To rationalize the denominator, you need to multiply the fraction by the conjugate:
√a / (√a - 2) × (√a + 2) / (√a + 2)
√a (√a + 2) / ((√a - 2) (√a + 2))
(a + 2√a) / (a - 4)
What is the gcf of 45 and 9?
Answer:
9
Step-by-step explanation:
The factors of 9 are: 1, 3, 9
The factors of 45 are: 1, 3, 5, 9, 15, 45
Then the greatest common factor is 9.
The GCF of 45 and 9 is 9.
To find the greatest common factor we need to prime factorize 9 and 45 and then find the product of the factors common between the two. This can be represented mathematically as follows:
[tex]45 = 3 \times 3 \times 5\\9 = 3 \times 3[/tex]
Thus we can see that two pair of 3 are common factors between 9 and 45. Thus the GCF [tex]= 3 \times 3 = 9[/tex]
Therefore, the GCF of 45 and 9 is 9.

This week, 300 tickets were sold to the school play. This is 120 percent of the number of tickets sold last week. How many tickets were sold last week for the school play?
_________ tickets sold
Answer:
250 tickets
Step-by-step explanation:
This week, the tickets sold was 300.
The # of tickets sold this week was 120% of last weeks ticket sales.
To find out the number of tickets sold last week, first convert 120% into a decimal.
120% = 1.2
Now, divide 300 [tickets sold this week] by 1.2.
If you do this, you get 250.
That means 250 tickets were sold last week.
To double check our answer, break down 120% again, but this time, differently.
100% + 20% = 120%
100% = 1
20% = 0.2
Now, multiply 250 by 1.
250 x 1 = 250.
Now multiply 250 by 0.2
250 x 0.2 = 50.
250 + 50 = 300
So, the amount of tickets sold last week is 250. I hope this helps! :)
Find all the values of x that make 0.1x + 0.25(102 - x) < 17.10 true.
Answer:
x > 560
Step-by-step explanation:
0.1x + 0.25(102 - x) < 17.10
simplify
0.1x + 25.5 - 0.25x < 17.10
subtract 25.5 from both sides
0.1x + 25.5 - 25.5 - 0.25x < 17.10 - 25.5
0.1x - 0.25x < - 84
- 0.15x < - 84
divide both sides by - 0.15
x < -84/-0.15 = 560
When you divide or multiply by a negative, the sign changes
x > 560
Hope this helps!
Please mark as brainliest.
To solve the inequality 0.1x + 0.25(102 - x) < 17.10, distribute, combine like terms, and isolate x to find that the values for x that make the inequality true are x > 56.
Explanation:To find the values of x that make the inequality 0.1x + 0.25(102 - x) < 17.10 true, we need to solve the inequality. First, we distribute 0.25 to get 0.1x + 25.5 - 0.25x < 17.10. Then, combining like terms gives -0.15x + 25.5 < 17.10. Next, we subtract 25.5 from both sides to get -0.15x < -8.4. Finally, dividing both sides by -0.15 gives x > 56.

12. A bridge is 1,595 feet long. Each cable holding up the
bridge is 1,983 feet longer than the bridge itself. How
long is each cable?
Answer:
3,578
Step-by-step explanation:
Add the two values together. If the bridge is 1,595 feet long, and if each cable holding that is 1,983 feet longer than the length of the bridge then adding them together is the way to go.
1,595+1,983=3,578
To get the length of each cable, you add the length of the bridge (1,595 feet) to the extra length of each cable (1,983 feet), which results in 3,578 feet.
Explanation:The problem is asking us to work with addition. The bridge is 1,595 feet long and each cable is 1,983 feet longer than the bridge. To find the length of each cable, we add the length of bridge and the extra length of the cable. That is, we add 1,595 feet (length of bridge) to 1,983 feet (extra length of cable).
Add 1,595 and 1,983. The result is the length of each cable, which equals 3,578 feet.Learn more about Addition here:

What is the degree of polynomial 3x⁴-4x³y+6x²y²-8x²y³-7y⁴+2
Answer:
5
Step-by-step explanation:
Find the degree of each monomial term of the polynomial. The highest degree is the answer.
deg(3x^4)=4
deg(-4x^3y)=3+1=4
deg(6x^2y^2)=2+2=4
deg(-8x^2y^3)=2+3=5
deg(-7y^4)=4
deg(2)=0
The highest degree there is 5 so that is the degree of the polynomial.
The degree of a polynomial is the highest power of any variable in that polynomial. For the polynomial 3x⁴-4x³y+6x²y²-8x²y³-7y⁴+2, because the highest power is 4, the degree of the polynomial is 4.
Explanation:The highest exponent of the variable in a polynomial determines its degree. In the provided polynomial, 3x⁴-4x³y+6x²y²-8x²y³-7y⁴+2, the degree of this polynomial is 4 because the highest power of the variable is 4. which can be seen in the terms 3x⁴ and -7y⁴.
It's important to note that while determining the degree of a polynomial, we consider the power (or degree) of individual terms and not their combined power. For example, in the term -4x³y, x has a degree of 3 and y has a degree of 1. The degree of -4x³y will still just be 3 (and not 4) as we only consider the highest degree within that term.

When you multiply a function by -1, what is the effect on its graph?
Answer:
The correct answer is C.
Step-by-step explanation:
When you multiply a real function by -1 you only change its sign in all the domain of definition. The positive part becomes negative, and the negative values becomes positive and the zeros are unaltered. So, it is no difficult to see that the multiplication by -1 is equivalent to make a reflection with respect to the x - axis.
