Given triangle ABC is similar to triangle DEC. Could you use the proportion 9/10=8.75/EC to determine the measure of EC? If yes, solve for EC. If no, rewrite the proportion and then solve for EC.
Answer:
9.72 approximately
Step-by-step explanation:
Given triangles are similar, to solve 9/10=8.75/EC we cross multiply expressions:
9EC = 87.5 now divide both sides by 9
EC = 9.72 approximately

what percentage of 205 is 54? can you also show your work
Answer:
the exact percentage is 26.34146. but i'd write it down as 26.34 or just 26
Step-by-step explanation:
we convert 54/205 into a percentage
Answer:
x = 26.34%
Step-by-step explanation:
Let the percentage be x:
205 * x% = 54
x% = 54 ÷ 205
x% = [tex]\frac{54}{205}[/tex]
[tex]\frac{x}{100}[/tex] = [tex]\frac{54}{205}[/tex]
x = [tex]\frac{54*100}{205}[/tex]
x = [tex]\frac{5400}{205}[/tex]
x = 26.34146341%
x = 26.34%

If q/18 = 5 what does q = to
Answer:
Q= 90
Step-by-step explanation:
To do this problem you need to get q by itself and to do that you would move the 18 over
When you move the 18 over however you need to multiply and you will get 90
When ever you want to get a variable by itself always remember to switch the sign so if it was positive then switch it to negative and vice versa. It will also apply to multiplication and division just like this one
Answer:
q=90
Step-by-step explanation:
first you're going to multiply both sides of the equation by 18
[tex]18[/tex]×[tex]\frac{q}{18}[/tex][tex]=18[/tex]×[tex]5[/tex]
next you're going to reduce the numbers with the greatest common factor 18
equation now: q=18×5
lastly you're going to multiply the numbers
18×5=90
so q=90

When two variables are highly positively correlated, the correlation coefficient will be _______.
When two variables are highly positively correlated, the correlation coefficient, r, would most likely be closer to 1 (0.7 - 1).
Correlation Coefficient (r)The correlation coefficient, r, shows the extent to which two variables are correlated. Correlation coefficient ranges from 1 to -1.
The stronger the correlation, the closer the correlation coefficient, r, is to -1 or 1.
Therefore, when two variables are highly positively correlated, the correlation coefficient, r, would most likely be closer to 1 (0.7 - 1).

Convert rational numbers to their equivalent decimals
Answer:
In order to change a rational number to a decimal, we just convert the number into the form of a fraction. We then divide the numerator with the denominator and find out the exact value of the division.
Determine the area, in square units, of the region bounded above by f(x)=11x−3 and below by g(x)=10x−5 over the interval [12,34]. Do not include any units in your answer.
Using integrals, it is found that the area bounded by the two curves in the interval is of 550 units squared.
How is the area under a graph found?The area under the graph of a curve bounded above by a function f(x) and below by a function g(x) over an interval [a,b] is given by:[tex]A = \int_a^b f(x) - g(x) dx[/tex]
In this problem:
The functions are [tex]f(x) = 11x - 3, g(x) = 10x - 5[/tex].The interval is [12, 34], hence [tex]a = 12, b = 34[/tex].Then:
[tex]A = \int_{12}^{34} 11x - 3 - (10x - 5) dx[/tex]
[tex]A = \int_{12}^{34} x + 2 dx[/tex]
[tex]A = \frac{x^2}{2} + 2x|_{x = 12}^{x = 34}[/tex]
Applying the Fundamental Theorem of Calculus:
[tex]A = \frac{34^2}{2} + 2(34) - \frac{12^2}{2} - 2(12) = 550[/tex]
The area is of 550 units squared.

Solve the equation:
[tex]x^4 - x^2 - 2 =0[/tex]
Answer:
±2
Step-by-step explanation:
This is a biquadratic equation, we must turn it into a quadratic one first before we solve it. So, let's say that x⁴ = y², therefore
[tex]y = \sqrt{x} [/tex]
and we turn it into the following quadratic equation:
y² - y - 2 = 0
then we solve it the way we solve a normal quadratic equations and find the roots:
D = 1 + 8 = 9
y1,2 = 1 ± 3 = 4, -2
[tex] \sqrt{x} = y[/tex]
We cannot find the square root of -2, so the solutions are only -2 and 2(because square root of 4 is equal to ±2)
A standard Ford F150 has a standard tire size of 25.7 inches in diameter. You decided to replace the standard tires with a tire with a diameter of 28.2 inches without updating the onboard computer. Last week you were stopped for speeding on the highway where the speed limit is 65 mph. With the change in tires, how fast was the truck actually traveling when the speedometer read 65 mph? If you had used 24 inch tires, what would the actual speed have been if the speedometer read 65 mph?
You should develop a document to be presented to the judge that explains your speed if you still had the original 25.7 inch tires, your actual speed with the new 28.2 inch tires, and your speed if you replaced the wheels with 24 inch tires.
The speed of the truck is higher (or lower) than the speedometer value
when a larger (or smaller) than standard sized tire.
Responses:
The speed with a 28.2 inches tire is actually approximately 71.3 mphThe actual speed if a 24 inch tire was used would be 60.7 mphHow does the size of the tire determine the speed?The standard tire size diameter = 25.7 inches
Diameter of the replacement tire = 28.2 inches
Circumference of the standard tire = π·25.7 inches
1 mile = 63,360 inches
65 miles = 65 × 63,360 inches
[tex]Number \ of \ rotation =\dfrac{63,360 \times 65}{\pi \times 25.7} \approx \mathbf{ 51,008.85}[/tex]
Distance travelled by the replacement tire with the same number of
rotations is therefore;
[tex]Distance =\dfrac{63,360 \ in. \times 65}{\pi \times 25.7 \ in.} \times \pi \times 28.2 \ in. \approx \mathbf{4519022.6\ in.}[/tex]
Actual distance travelled in one hour = 4519022.6 ÷ 63,360 ≈ 71.32
The actual speed of the truck when the speedometer read 65 mph is; 71.32 mph
Second part; Tire diameter = 24 inches
Distance traveled in one hour = 51,008.85 × π × 24 ≈ 3845976.68
Distance traveled in one hour ≈ 3845976.68 inches
3845976.68 inches ≈ 60.7 miles
The actual speed if a 24 inch tire is used is approximately 60.7 mph
Details of the truck speed with different sized wheels
The speed if the original 25.7 inch tires is used will be the speed on the speedometer, which is 65 mph. However the actual speed with the new 28.2 inch tires is approximately 71.32 mph. The speed if the wheels were replaced with a 24 inch tire is approximately 60.7 mphLearn more about rotation and speed here:
