Answer:
C. y<3
Step-by-step explanation:
We are required to determine the solution set of the inequality
[tex]15y-9<36[/tex]
Step 1: Add 9 to both sides
[tex]15y-9+9<36+9\\15y<45[/tex]
Step 2: Divide both sides by 15
[tex]15y \div 15<45 \div 15\\y < 3[/tex]
The solution set of the given inequality is: y<3.
The correct option is C.

Answer:
x = 6
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, thus
6x - 15 = x + 15 ( subtract x from both sides )
5x - 15 = 15 ( add 15 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Answer:
X=6 Read explination
Step-by-step explanation:
A parallelogram has the perrimeter of both opposite sides equal
So we know that
6x-15=x+15
This is because in a parrellelogram the opposite sides are equal
so breaking it down
6x-15=x+15
(add 15 to both sides)
6x=x+30
(subtract x from both sides)
5x=30
(divide both sides by 5)
x=6

Find the value of q.
Please
Answer:
q = -7
Step-by-step explanation:
3 ^ -q * 1/27 = 81
Rewriting each as a power of 3
3 ^ -q * 3^ -3 = 3 ^4
We know that a^b * a^ c = a^ ( b+c)
3 ^ (-q -3) = 3 ^4
The bases are the same so the exponents are the same
-q-3 = 4
Add 3 to each side
-q-3+3 = 4+3
-q =7
Divide by -1
q = -7

using difference of squares?
Answer:
A. [tex] {-\frac{5+5\sqrt 3 }{2}}[/tex]
Step-by-step explanation:
Please wait for more explanation:
[tex] \frac{5}{1-\sqrt 3}= \frac{5}{1-\sqrt 3}\times \frac{1+\sqrt 3}{1+\sqrt 3}\\\\
= \frac{5(1+\sqrt 3) }{1^2 -(\sqrt 3) ^2}\\\\
= \frac{5+5\sqrt 3 }{1 -3}\\\\
= \frac{5+5\sqrt 3 }{-2}\\\\
=\huge\purple {\boxed {-\frac{5+5\sqrt 3 }{2}}} \\[/tex]
The fraction 5/1-√3 can be rewritten if its denominator is rationalized using difference of squares as -5(1 + √3)/2.
What is simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression.
Simplification usually involves making the expression simple and easy to use later.
To rationalize 5÷1-√3, by the conjugate of 1 - √3 = 1 + √3.
So 5 ÷ (1 - √3) = 5/(1 - √3),
we multiply the expression by the conjugate of the denominator, we have,
5/(1 - √3) × (1 + √3)/(1 + √3)
= 5(1 + √3)/[(1 - √3) × (1 + √3)]
= 5(1 + √3)/(1² - (√3)²)
= 5(1 + √3)/(1 - 3)
= 5(1 + √3)/-2
= -5(1 + √3)/2

the focal length F of a lens made by combining two lenses of focal length U and V is given I/F=I/U+I/V
A.make V the subject of the formula.
B.find V when F=6,U=10
Answer:
a). [tex]V=\frac{U.F}{U-F}[/tex]
b). V = 15 units
Step-by-step explanation:
Focal length F of a lens made by combining two lenses of different focal lengths U and V will be,
[tex]\frac{1}{F}=\frac{1}{U}+\frac{1}{V}[/tex]
A). By solving the given formula,
[tex]\frac{1}{V}=\frac{1}{F}-\frac{1}{U}[/tex]
[tex]\frac{1}{V}=\frac{U-F}{U.F}[/tex]
[tex]V=\frac{U.F}{U-F}[/tex]
B). If F = 6 and U = 10 then we have to find the value of V.
By substituting the given values in the formula,
[tex]V=\frac{6\times 10}{10-6}[/tex]
[tex]V=\frac{60}{4}[/tex]
V = 15 units
Therefore, focal length (V) of the lens = 15 units

Between July 1, 2000 and July 1, 2007, the estimated population of a city declined from 3487 to 2653. What was the percent decrease to the nearest tenth?
Answer:
23.9% decrease
Step-by-step explanation:
The percentage change is calculated from ...
pct change = ((new value)/(old value) -1) × 100%
= (2653/3487 -1) × 100% = -0.2392 × 100%
pct change = -23.9% . . . . rounded to tenths
The population decreased by 23.9% in the given time period.

The number of traffic accidents that occur on a particular stretch of road during a month follows a Poisson distribution with a mean of 8.1. Find the probability that the next two months will both result in three accidents each occuring in this stretch of road
Answer:
P = 0.00072
Step-by-step explanation:
If the number of traffic accidents that occurs follows a Poisson distribution, the probability that x traffic accidents occurs is:
[tex]P(x)=\frac{e^{-m}(m^x)}{x!}[/tex]
Where m is the mean. So replacing m by 8.1 accidents/monts, we get:
[tex]P(x)=\frac{e^{-8.1}(8.1^x)}{x!}[/tex]
So, the probability that the next two months will both result in three accidents each occurring in this stretch of road is calculated as:
[tex]P(3)*P(3)=\frac{e^{-8.1}(8.1^3)}{3!}*\frac{e^{-8.1}(8.1^3)}{3!}\\P(3)*P(3)=0.00072[/tex]

Given that sin x < cos x and 0°< x < 90°,state a possible value of x. Explain your answer clearly.
Answer:
30°Step-by-step explanation:
Given sinx< cos x and 0°< x < 90°, to get the possible value of x, we need to solve the given inequality for x.
sinx< cos x
Dividing both sides by cos x
sin x/cos x < cos x/cos x
tan x < 1
x < [tex]tan^{-1}1[/tex]
x < 45°
Since x is less than 45°, then one of the possible value of x can be 30° since 30° is less than 45° and 30° falls within the given range of values.

Answer:
-4 + 4
Step-by-step explanation:
It is -4 + 4 because if you imagine on a number line, you go left 4 (since it is negative) and add 4, so you go to the right 4, which leaves to 0.
Or, you can think of it like this:
+4 - 4

Find the coordinates of point BBB on \overline{AC} AC start overline, A, C, end overline such that the ratio of ABABA, B to BCBCB, C is 2:32:32, colon, 3.
Answer:
B(-2,-3).
Step-by-step explanation:
The given points are A(-6,-5) and C(4,0).
We need to find the coordinates of point B on segment AC such that AB:BC=2:3.
It means point B divides the line segment AC in the ratio of 2:3.
Section formula: If a point divide a line segment in m:n, then
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Using section formula, the coordinates of point B are
[tex]B=\left(\dfrac{2(4)+3(-6)}{2+3},\dfrac{2(0)+3(-5)}{2+3}\right)[/tex]
[tex]B=\left(\dfrac{8-18}{5},\dfrac{0-15}{5}\right)[/tex]
[tex]B=\left(\dfrac{-10}{5},\dfrac{-15}{5}\right)[/tex]
[tex]B=\left(-2,-3\right)[/tex]
Therefore, the coordinates of point B are (-2,-3).
