Step-by-step explanation:
2:3
Answer:
2:3.
Step-by-step explanation:
If you turn 8:12 into a fraction (8/12), then make it simplest form, it would be 2/3.
2/3 as a ratio is 2:3. Therefore, 2:3 is equivalent to 8:12.
How much principal must be deposited to earn $1,000 simple interest in 250 days at a rate of 5.05%?
The principal must be deposited to earn $1,000 simple interest in 250 days at a rate of 5.05% is $28,514.85
How is simple interest determined?
The simple interest on deposit is determined as the principal multiplied by the simple interest rate and the time of the deposit as shown below:
I=PRT
I=simple interest earned=$1,000
P=principal deposited=unknown
R=simple interest rate =5.05%
T=number of days that deposit lasted as a fraction of number of days in a year=250/360
$1000=P*5.05%*250/360
$1000=P*0.0350694444444444
P=$1000/0.0350694444444444
P=$28,514.85

The value of the exponential expression is 4 which is option (C).
Exponential equations, as the name suggests, involve exponents. The exponent (radix) of a number indicates how many times the number (radix) is multiplied.A number's exponent indicates how many times the number has been multiplied by itself. For example, 2×2×2×2 can be written as 24 because 2 is multiplied by 4. Here 4 is called the "exponent" or "power". In general, xn means multiply x by n times. Power law is given by[tex](a^m)^n=a^{m\times n}[/tex]We can write 16 as [tex]4^2[/tex] .

If James' total marks for the four terms was 256,and he represented his marks by a pie chart, what would be the size of the angle representing term 2
A possible name for this type of chart is Scatter Chart. James scored the most at first glance.
James tried to make his results look impressive in his first graph by drawing the graph from right to left instead of left to right.
This is a schematic of a data set showing the relationships between variable quantities. So if you look closely at the chart from left to right, you can see that Jane is the clear winner. Because James' results are not good and continue to decline.
Pie charts can be used to display percentages of the whole, representing percentages at a particular point in time.

Determine the solutions of the equation:
x = −11 and x = 5
x = −81 and x = 45
x = −99 and x = 45
x = −99 and x = 99
The solutions of the absolute value equation are x = −99 and x = 45.
How to determine the solutions of the absolute value equation?Here we have the absolute value equation:
| (1/3)*x + 9| - 3 = 21
First, we can add 3 in both sides so we get:
| (1/3)*x + 9| = 21 + 3 = 24
This can be decomposed into two equations, we will get:
(1/3)*x + 9 = 24
(1/3)*x + 9 = -24
Solving these two we can get the two solutions.
The first one gives.
(1/3)*x = 24 - 9 = 15
x = 3*15 = 45
The second one gives:
(1/3)*x = -24 - 9 = -33
x = 3*-33 = -99
The solutions are x = −99 and x = 45.

Answer: a. 17
b. an=-2.5n+24.5
Step-by-step explanation:
Term number: 3, 4, 5
Terms: 17, 14.5, 12
Term 3 is 17, term 4 is 14.5, and term 5 is 12.
a. The corresponding value to term 3 is 17.
b. Slope formula: m=(y2-y1)/(x2-x1) where x=term number and y=term.
m=(17-14.5)/(3-4)
m=2.5/(-1)
m=-2.5
y=mx+b ==> Linear equation with slope
12=-2.5(5)+b ==> substitute a term number and it's corresponding term
12=-12.5+b
b=12+12.5
b=24.5
y=-2.5x+24.5
an=-2.5n+24.5 ==> convert linear equation back to an form.

(x + 2)^2 – 46 = 24
Answer:
x = - 2 ± [tex]\sqrt{70}[/tex]
Step-by-step explanation:
(x + 2)² - 46 = 24 ( add 46 to both sides )
(x + 2)² = 70 ( take square root of both sides )
x + 2 = ± [tex]\sqrt{70}[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\sqrt{70}[/tex]

Explanation:
The rule we use is [tex](\text{x}, \text{y}) \to (-\text{x}, \text{y})[/tex] when reflecting over the vertical y axis.
The x coordinate flips from positive to negative, or vice versa. The y coordinate stays the same. So a point like (-6, 5) reflects over to (6, 5). The x coordinate -6 flipped to +6 or simply 6. The y coordinate stayed at 5.
Use this idea to reflect the other points.

find the volume of the parallelepiped with adjacent edges pq, pr, and ps. p(−2, 1, 0), q(4, 4, 4), r(1, 4, −1), s(3, 6, 1)
The volume of the parallelepiped with adjacent edges PQ, PR, and PS is 24 cubic units.
What is parallelepiped?Six parallelograms come together to form a three-dimensional shape called a parallelepiped (the term rhomboid is also sometimes used with this meaning). It is comparable to a parallelogram in the same way that a cube is comparable to a square. In Euclidean geometry, the four concepts—parallelepiped and cube in three dimensions, parallelogram, and square in two dimensions—are specified; however, only parallelograms and parallelepipeds exist in the setting of a more generic affine geometry, where angles are not discriminated.
There are three similar descriptions of a parallelepiped:
A polyhedron called a hexahedron, which has six parallelogram-shaped facesThree pairs of parallel faces on a hexahedron, andA prism with a parallelogram as its base.We have been that p(−2, 1, 0), q(4, 4, 4), r(1, 4, −1), and s(3, 6, 1) are the adjacent edges of parallelepiped
PQ = Q-P = <6,3,4>

How to express ABC in terms of x?
Answer:
∠ ABC = 180 - 2x
Step-by-step explanation:
AB and BC are congruent , so the triangle is isosceles with base angles congruent , that is
∠ A = ∠ C = x
the sum of the 3 angles in the triangle = 180° , then
∠ ABC + x + x = 180
∠ ABC + 2x = 180 ( subtract 2x from both sides )
∠ ABC = 180 - 2x

14.7 kilograms is how many pounds?
The given kilograms in pounds is 32.407952541177 pounds.
Given that there are 14.7 kilograms.
The SI unit of mass is the kilogram (kg). It is equal to the mass of the international prototype of the kilogram and One kg is approximately equal to 2.20462262184878 pounds.
One pound, the international peso, is legally defined as exactly 0. 5359237 kilograms.
To calculate the kilogram value with its corresponding value in pounds, simply multiply the quantity in kilograms by 2.20462262184878.
Pounds = kilograms × 2.20462262184878
Now, substitute kilograms=14 kilograms, we get
Pounds = 14.7× 2.20462262184878
Pounds=32.407952541177
Hence, in 14.7 kilograms there are 32.407952541177 pounds.

Find the point-slope equation for
the line that passes through the
points (-2, -20) and (9, 79). Use
the first point in your equation.
y - [?] = [](x-[])
The point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.
We are given the points as:
(- 2 , - 20) and ( 9 , 79)
We will first find the slope:
Slope = m = y₂ - y₁ / x₂ - x₁
m = 79 + 20 / 9 + 2
m = 99 / 11
m = 9
Now, we have to find the point-slope equation for the line that passes through the points (- 2, - 20) and (9, 79).
The point slope equation is:
y - [y₁] = [m](x-[x₁])
Substituting the values, we get that:
y + 20 = 9 ( x + 2 )
y + 20 = 9 x + 18
9 x - y + 18 - 20 = 0
9 x - y - 2 = 0
Therefore, the point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.

The table shows the proportional relationship between a hedgehog's
weight loss and the number of days of hibernation. How much weight does
the hedgehog lose during 120 days of hibernation?
Explain how you know that the relationship between the hedgehog's weight
loss and the number of days of hibernation is proportional.
The hedgehog’s total change in weight over 120 days is ____ ounces.
Answer:
-3.6
Step-by-step explanation:
proportional means the amount on the right is amount on the left multiplied by some coefficient - proportion. The proportion is calculated by dividing one side by another. Since you need to calculate weight based on days, you need the proportion of weight/days, so divide -0.27/9 or -0.78/26, in all cases you'll receive -0.03. This means for each day in hibernation hedgehog loses 0.03 pounds. 120 days will be 120*-0.03 which gives you -3.6

An inequality that represents given scenario is 5 + 2.75x ≤ 21
For given question,
The $21 means that there is a limit to the number of stops she can take using the train.
From given information, we have the following parameters:
Initial Fee = $5
Rate per stop = $2.75
Amount = $21
The inequality that represents the scenario is calculated using:
Initial Fee + Rate × Number of stops ≤ Amount
We use ≤ because the total charges must not exceed the amount.
Let the number of stops be x.
The above formula becomes
5 + 2.75x ≤ 21
Therefore, an inequality that represents given scenario is 5 + 2.75x ≤ 21
