Pls answer ASAP!! thanks yall
Answer:
x = -7/5
or x = -1.4
Step-by-step explanation:
2/10 - 4/5 = -3/5
-3/5 * 7 = -21/5
-21/5 ÷ 3 = -7/5
A company makes bicycles in two sizes. The smaller bicycle weighs 18.5 pounds. The larger bicycle weighs 1 1/4 times as much as the smaller bicycle. How many pounds does the larger bicycle weigh?
Answer:
[tex] \displaystyle23.125 \: \text{pounds}[/tex]
Step-by-step explanation:
we are given that,
the weight of a smaller bicycle is 18.5 poundsthe weight of a larger bicycle is 1¼ times as much as the smaller bicyclein order to figure out the weight of the larger bicycle we can consider using equation
let the weight of the larger bicycle be L
according to the second condition
we acquire
[tex] \displaystyle L = 18.5 \times 1\frac{1}{4} [/tex]
to simplify the mixed fraction to improper fraction we can use the formula given by
[tex] \displaystyle \rm c\frac{a}{b} \xrightarrow{ \text{improper fraction}} \frac{b \times c + a}{b} [/tex]
by using the formula we get
[tex] \displaystyle L = 18.5 \times \frac{5}{4} [/tex]
simplify multiplication:
[tex] \displaystyle L =\frac{92.5}{4} [/tex]
simplify division:
[tex] \displaystyle L =23.125[/tex]
hence,
the larger bicycle weighs 23.125 pounds

derivative of
[tex] \frac{ {3x}^{2} - 2x - 1 }{ {x}^{2} } [/tex]
Show a step.
Answer:
[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]
Step-by-step explanation:
we would like to figure out the derivative of the following:
[tex] \displaystyle \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]
to do so, let,
[tex] \displaystyle y = \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]
By simplifying we acquire:
[tex] \displaystyle y = 3 - \frac{2}{x} - \frac{1}{ {x}^{2} } [/tex]
use law of exponent which yields:
[tex] \displaystyle y = 3 - 2 {x}^{ - 1} - { {x}^{ - 2} } [/tex]
take derivative in both sides:
[tex] \displaystyle \frac{dy}{dx} = \frac{d}{dx} (3 - 2 {x}^{ - 1} - { {x}^{ - 2} } )[/tex]
use sum derivation rule which yields:
[tex] \rm\displaystyle \frac{dy}{dx} = \frac{d}{dx} 3 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]
By constant derivation we acquire:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]
use exponent rule of derivation which yields:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ - 1 -1} ) - ( - 2 {x}^{ - 2 - 1} )[/tex]
simplify exponent:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ -2} ) - ( - 2 {x}^{ - 3} )[/tex]
two negatives make positive so,
[tex] \displaystyle \frac{dy}{dx} = 2 {x}^{ -2} + 2 {x}^{ - 3} [/tex]
further simplification if needed:by law of exponent we acquire:
[tex] \displaystyle \frac{dy}{dx} = \frac{2 }{x^2}+ \frac{2}{x^3} [/tex]
simplify addition:
[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]
and we are done!

Answer:
1) Missing Length: 20 m
Equation: [tex]c^2=16^2+12^2[/tex]
2) Missing Length: 100√5 mm
Equation: [tex]c^2=100^2+200^2[/tex]
Step-by-step explanation:
1) We can use Pythagorean Theorem to solve this triangle and find the length of the hypotenuse.
[tex]c^2=16^2+12^2[/tex]
[tex]c^2=256+144[/tex]
[tex]c^2=400[/tex]
Luckily, 400 is a perfect square :)
[tex]c=20[/tex]
So, the length of the hypotenuse is 20 cm.
2) Again, we can use the Pythagorean Theorem to find the missing length.
[tex]c^2=100^2+200^2[/tex]
[tex]c^2=10000+40000[/tex]
[tex]c^2=50000[/tex]
[tex]c=\sqrt{50000}[/tex]
But, we can still simplify the radical.
[tex]\sqrt{50000}[/tex]
[tex]=100\sqrt{5}[/tex]
So, the length of the missing length is 100√5 cm.

Rajesh gave 1/2 of his provident fund to his wife,1/4 to his son and the remainder was to be divided equally between his two brothers so that each brother got Rs 10000.
What was the amount of provident fund?
Answer:
$ 80 000
Step-by-step explanation:
provident fund -- x
Wife -- 1/2 of x
Son -- 1/4 of x
Two brothers -- x - (x/2 - x/4)
Therefore, x - (x/2 - x/4) / 2 = 10 000
x = 80 000
Therefore, the amount of provident fund is $ 80 000

Given the definitions of f(x) and g(x)
below, find the value of f(g(-4)). F(x)=4x+6 g(x)=x^ 2+x-9
Answer:
[tex]f(g(-4)) = 18[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4x + 6[/tex]
[tex]g(x) = x^2 + x - 9[/tex]
Required
Find f(g(-4))
First, calculate f(g(x))
We have:
[tex]f(x) = 4x + 6[/tex]
[tex]f(g(x)) = 4g(x) + 6[/tex]
Substitute: [tex]g(x) = x^2 + x - 9[/tex]
[tex]f(g(x)) = 4[x^2 + x - 9] + 6[/tex]
Open bracket
[tex]f(g(x)) = 4x^2 + 4x - 36 + 6[/tex]
[tex]f(g(x)) = 4x^2 + 4x-30[/tex]
Substitute [tex]-4[/tex] for [tex]x[/tex]
[tex]f(g(-4)) = 4*(-4)^2 + 4*(-4)-30[/tex]
[tex]f(g(-4)) = 64 -16 -30[/tex]
[tex]f(g(-4)) = 18[/tex]

Michael surveyed a random sample of students in his school about the number of sports they play. There are 300 students in Michael's school. Use the
results of the survey to estimate the number of students in Michael's school who play exactly one sport.
Answer:
75 students
Step-by-step explanation:
From the table, we can calculate the total number of students surveyed by Michael:
Total student surveyed = 13 + 15 + 32 = 60 students
We can see that out of the 60 students, 15 students played exactly one sport. Hence:
Proportion of students playing exactly one sport = 15 / 60 = 0.25
Based on the result of the survey, if they are 300 students, number of students playing exactly one sport is:
Number of students playing exactly one sport = proportion * total students = 0.25 * 300 students = 75 students
