Scott was considering the equation 5 - x = 12. He said, "That seems
impossible. How can I start with 5 and subtract from it and have more than
5 as the difference?" Write a note to Scott explaining what the solution for
x is and why it is possible. *
Answer:
-7
Step-by-step explanation:
[tex]5 - x = 12 \\ 5 - 12 = x \\ - 7 = x[/tex]
it is possible because x is just a letter representing the unknown nos

The dimensions of a box are x, 2x, and 3x. Each dimension is increased by 2. Calculate the volume of the box.
9514 1404 393
Answer:
6x^3 +22x^2 +24x +8
Step-by-step explanation:
The dimensions of the larger box are ...
(x+2), (2x+2), and (3x+2)
The volume is the product of these dimensions.
V = LWH
V = (x+2)(2x+2)(3x+2) = (x +2)(6x^2 +10x +4)
V = 6x^3 +22x^2 +24x +8
The volume of the box is 6x^3 +22x^2 +24x +8.

Step-by-step explanation:
An initial population of 415
ducks increases at an annual
rate of 32%. Write an
exponential function to model
the duck population.
Answer:
The exponential function to model the duck population is:
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Step-by-step explanation:
In order to calculate the duck population you can use the formula to calculate future value:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:
f(n)=415*(1+0.32)^n
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years

Circle T is shown. Angle Q S R intercepts arc Q R. Angle Q S R is 52 degrees. What is the measure of arc Q R? 26° 52° 104° 128°
Answer:
104 degrees'
Step-by-step explanation:
Find the diagram attached
According to the theorem;
Angle at the vertex is half the angle at its intercepted arc
Given
Angle at the vertex = 52 degrees
Angle at the intercepted arc = arc QR
Hence;
52 = 1/2 arcQR
Cross multiply
52 * 2 = arcQR
104 = arc QR
Swap
arc QR = 104 degrees'
Answer:
C)104

Dana gets paid $10 per hour plus a $10 bonus for the week. Tommy gets paid $9 per hour plus $13 bonus for the week. Set up a system of equations and tell how many hours they would need to work to earn the same amount.
A) 3 hours
B) 40 hours
C) 20 hours
D) 10 hours
Answer:
A) 3 hours
Step-by-step explanation:
x = per hour
y = total
Dana:
y = 10x + 10
Tommy:
y = 9x + 13
Combined (Solve for x):
y = 10x + 10
y = 9x + 13 (Multiply by -1)
y = 10x + 10
-y = -9x - 13
0 = x - 3
x = 3
6 The interior angles of a triangle always sum to 180°. The measure of ZC is 8°
less than the measure of ZD. Find the values of x and y.
Answer:
m<D=67
m<C=59
Step-by-step explanation:
m<C=y-8
m<D=y
m<A=54
put all the angles together and equal to 180
(y-8)+(y)+(54)=180
now solve the equation
67=y
(67)-8=59
find the value of x +65+115+115

Sam has 24/4 18 nickels and 36 times he wants to divide the coins into groups so that each group is worth the same amount of money what is the greatest number of groups say I'm can make using all the coins
Answer:
5 and each group would be worth $2.10
Step-by-step explanation:
Sam has 24 quarters, 18 nickels, and 36 dimes. He wants to divide the coins into groups so that each group is worth the same amount of money. What is the greatest number of groups Sam can make using all the coins?
HURRY PLEASE
Convert this monies to dollar
Quarters - 24 x 0.25 = $6
Nickels = 18 x 0.05 = $0.9
Dimes = 36 x 0.1 = $3.6
sum of these amounts = $10.50
the greatest group is 5 and each group would be worth $2.10
The students put recycling bins for cans and bottles in the cafeteria and teaches lounge. At the end of last week, there was a total of 48.9 pounds of cans and bottles. They split them evenly into 3 bags. How many pounds were in each bag?
Answer:
16.3
Step-by-step explanation:
There was a total of 48.9 pounds of cans and bottles
They were split evenly in 3 bags
Hence the number of each pounds in the bag can be calculated as follows
= 48.9/3
= 16.3
Hence 16.3 pounds are found in each bags
Han has 10 cubes, each 5 inches on a side. Find the total volume of Han's cudes Express your answer as an expression using an exponent.
Answer:
2 * 5⁴
Step-by-step explanation:
Given :
Number of cubes = 10
Side length, a of each cube = 5
The volume of a cube = (side length)³
Hence, the volume of each of Han's cube = 5³
Therefore, the total volume will be :
Volume or cube * number of cubes
5³ * 10
10 = 2 * 5 = 2 * 5¹
5³ * 2 * 5¹
2 * 5^(3 +1)
2 * 5⁴
Lincoln estimates the height of a tree. Lincoln's estimate has a 6% error.
The actual height of the tree is 17 feet. What could be Lincoln's estimate?
Choose all the correct answers.
A 11
B 15.98
C 18.02
D 16.94
E 23
Answer: B, C and D
Explained:
17 * .06 = 1.02
So 15.98 - 18.02 are all within Lincoln’s estimate and error rate.
B, C and D are all within the 6% error rate. So the answers are B, C and D.
Uh whats the area of the figure??????
Answer:
42.5
Step-by-step explanation:
The figure shown is a trapezoid
The area of a trapezoid can be calculated using this formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
The trapezoid has the following dimensions
base 1 = 7 m
base 2 = 10 m
height = 5 m
Given this information we plug in the values into the formula
[tex]A =\frac{7+10}{2} 5\\7+10=17\\\frac{17}{2} =8.5\\8.5*5=42.5 \\A=42.5[/tex]
So we can conclude that the area of the trapezoid is 42.5 square units

Answer:
[tex]tan(\theta) = \frac{3}{4}[/tex]
Step-by-step explanation:
Remember the trigonometric ratios, keep in mind that the way the side is referred to is based on its position relative to the angle getting referenced. The side next to the referenced angle ([tex]\theta[/tex]) is called the adjacent side, the one opposite the angle is called the opposite side, and the side opposite the right angle of the triangle is called the hypotenuse.
[tex]sin (sine) = \frac{opposite}{hypotenuse}\\\\cos (cosine) = \frac{adjacent}{hypotenuse}\\\\tan(tangent) = \frac{opposite}{adjacent}[/tex]
In this problem, one is asked to find the value of ([tex]\theta[/tex]) with regards to a trigonometric function. One is given the opposite and adjacent sides, it would make the most sense to use the trigonometric function (tangent). Substitute the sides into their respective place, and simplify to find the value of the trigonometric function.
[tex]tan(\theta) =\frac{15}{20}\\\\\\tan(\theta)=\frac{3}{4}[/tex]
