PLEASE HELP ME ITS MY LAST QUESTION!!
Write three very large numbers and three very small numbers. Now write them using scientific notation. Then
perform one calculation with the numbers.
100 = 10^2
1000 = 10^3
10000 = 10^4
0.1 = 10^(-1)
0.01 = 10^(-2)
0.001 = 10^(-3)
Now,
100 × 0.1 = 10^2 × 10^(-1)
= 10

Step-by-step explanation:
It is given that yvaries directly as x. If y= 5 when x= 4 determine the constant of variation,
Answer:
[tex]k=\dfrac{5}{4}[/tex]
Step-by-step explanation:
Given that,
y varies directly as x. It means,
y = kx
Where
k is the constant of variation
or
[tex]k=\dfrac{y}{x}\\\\k=\dfrac{5}{4}[/tex]
So, the constant of variation is [tex]\dfrac{5}{4}[/tex].

Answer:
⅔ (option two)
Explanation:
on a cube numbered 1 to 6, only four numbers (1, 2, 3 and 4) are smaller than 5. there is an equal chance of you rolling any side on the dice, so your chances of rolling one of those four numbers would be 4/6, which can be simplified to ⅔.

A health club manager wants to determine whether the members would prefer a new sauna or a new steam room. The club surveys 50 of its 600 members. What is the population of this study? The population is all 50 members of the health club. The population is all 600 and 50 members of the health club. The population is all 600 members of the health club. The population is all 30,000 members of the health club.
Answer:
The population is all 600 members of the health club
Explanation:
50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.

3/4 years equal how many months
Answer:
9
Step-by-step explanation:
The line segment between (9,6) and (-2,-1) is bisected at (3.5,2.5). Find the y-intercept of the perpendicular bisector.
Ans: y-intercept = (0, _____)
Answer:
Y-intercept is (0,8)
Step-by-step explanation:
Firstly, we need to get the equation of the line segment
We have the general equation as;
y = mx + b
m is the slope and b is the y-intercept
So for the slope between (9,6) and (-2,-1); we have
m = (y2-y1)/(x2-x1)
m = (-1-6)/(-2-9) = -7/-11 = 7/11
Mathematically, when two lines are perpendicular, their slopes have a product of -1
Let the slope of the second line be m
m * 7/11 = -1
7m = -11
m = -11/7
The equation of the second line is;
y = mx + b
y = -11x/7 + b
The line passes through the point (3.5,2.5)
So,
2.5 = -11/7(3.5) + b
2.5 = -5.5 + b
b = 2.5 + 5.5
b = 8
so the y-intercept of the perpendicular bisector is 8
can someone help on Part A and Part B please thanks
(5th grade math)
Answer: 18 quarts for Part a
9 gallons for part b
Step-by-step explanation:
Answer:
Part A: 18
Part B: 4 1/2
Step-by-step explanation:
Part A:
He needs to triple his recipe by 3, so 12 x 3. So you get 36. The question was how many quarts does he need. So 36 divided by 2 is 18. So 18 quarts is needed!
Part B: We need to find out how many gallons he needs, we already know that he has 18 quart. There are 4 quarts in a gallon. So 18 divided by 4 is 4 1/2.
Good Luck And Hope this helps!

a2 = -8 and a5 = -512
Find a10
Answer:
The value of a₁₀ is -1352
Step-by-step explanation:
a₂ = -8
a₅ = -512
Now,
a₂ = -8 can be written as
a + d = -8 ...(1) and
a₅ = -512 can be written as
a + 4d = -512 ...(2)
Now, from equation (2) we get,
a + 4d = - 512
a + d + 3d = - 512
(-8) + 3d = - 512 (.°. a + d = -8)
3d = - 512 + 8
3d = - 504
d = - 504 ÷ 3
d = - 168
Now, for the value of a put the value of d = -168 in equation (1)
a + d = -8
a + (-168) = -8
a - 168 = -8
a = 168 - 8
a = 160
Now, For a₁₀
a₁₀ = a + 9d
a₁₀ = 160 + 9(-168)
a₁₀ = 160 - 1512
a₁₀ = -1352
Thus, The value of a₁₀ is -1352

What's the slop and y intercept of 4y = 2x - 12
Answer:
slope: [tex]\frac{1}{2}[/tex]
y-intercept: (0,-3)
Step-by-step explanation:
First, place the equation in slope-intercept form to identify the slope and y-intercept easily. Isolate the y in the equation to do this:
[tex]4y = 2x-12\\\frac{4}{4} y = \frac{2}{4} x-\frac{12}{4} \\y = \frac{1}{2} x-3[/tex]
Now that the equation is in slope-intercept form, it is much easier to find the slope and y-intercept of the equation. Remember that the slope-intercept formula is [tex]y = mx + b[/tex].
In an equation written in slope-intercept form, the [tex]m[/tex], or the coefficient of the x-term, represents the slope. So, the slope of his equation is [tex]\frac{1}{2}[/tex]. Also, the [tex]b[/tex], or the constant on the right side of the equation, represents the y-intercept. So, the y-intercept of this equation is (0,-3).
What is the shortest possible perimeter for an arrangement with an area of 15 square feet? Please get me the answer as soon as possible!!!!!!!!!!!
Answer:
The shortest possible perimeter is: [tex]4\sqrt{15}[/tex]
Step-by-step explanation:
Given
[tex]A = 15[/tex] --- area
Required
Find the shortest possible perimeter
Area is calculated as:
[tex]A=l * b[/tex]
This gives:
[tex]l * b = 15[/tex]
Make l the subject
[tex]l=\frac{15}{b}[/tex]
Perimeter is calculated as:
[tex]P =2(l + b)[/tex]
Substitute [tex]l=\frac{15}{b}[/tex]
[tex]P =2(\frac{15}{b} + b})[/tex]
Rewrite as:
[tex]P =2(15b^{-1} + b)[/tex]
Differentiate and minimize;
[tex]P' =2(-15b^{-2} + 1)[/tex]
Minimize by equating P' to 0
[tex]2(-15b^{-2} + 1) = 0[/tex]
Divide through by 2
[tex]-15b^{-2} + 1 = 0[/tex]
[tex]-15b^{-2} = -1[/tex]
Divide through by -1
[tex]15b^{-2} = 1[/tex]
Rewrite as:
[tex]\frac{15}{b^2} = 1[/tex]
Solve for b^2
[tex]b^2 = \frac{15}{1}[/tex]
[tex]b^2 = 15[/tex]
Solve for b
[tex]b = \sqrt{15[/tex]
Recall that: [tex]P =2(\frac{15}{b} + b})[/tex]
[tex]P = 2 * (\frac{15}{\sqrt{15}} + \sqrt{15})[/tex]
[tex]P = 2 * (\sqrt{15} + \sqrt{15})[/tex]
[tex]P = 2 * (2\sqrt{15})[/tex]
[tex]P = 4\sqrt{15}[/tex]
The shortest possible perimeter is: [tex]4\sqrt{15}[/tex]
would n-3/n+3 cancel out?
Answer:
Let's work this out.
n - 3 / n + 3

Charley's grade in the three quarters are 85, 88, and 92. If she targets to have an average
grade of greater than 90 in the four quarters this school year, what is the least grade she
should have for the fourth quarter?
Step-by-step explanation:
We can set up an average equation in the form, where x is the last score in the fourth quarter:
[tex]\frac{85 + 88 + 92 + x}{4} = 90[/tex]
[tex]85 + 88+92 + x =360\\\\x = 95[/tex]
She needs at least a 95 on the last quarter to average 90 in all four quarters.

Given:
[tex](\sin x)^2+(\cos x)^2=1[/tex]
[tex]\cos \theta = \dfrac{4\sqrt{2}}{7}[/tex]
To find:
The value of [tex]\sin \theta[/tex].
Solution:
We have,
[tex]\cos \theta = \dfrac{4\sqrt{2}}{7}[/tex]
Putting this value in the Pythagorean identity, we get
[tex](\sin \theta)^2+(\cos \theta)^2=1[/tex]
[tex](\sin \theta)^2+\left(\dfrac{4\sqrt{2}}{7}\right)^2=1[/tex]
[tex](\sin \theta)^2+\dfrac{16(2)}{49}=1[/tex]
[tex](\sin \theta)^2+\dfrac{32}{49}=1[/tex]
[tex](\sin \theta)^2=1-\dfrac{32}{49}[/tex]
[tex](\sin \theta)^2=\dfrac{49-32}{49}[/tex]
[tex](\sin \theta)^2=\dfrac{17}{49}[/tex]
Taking square root on both sides, we get
[tex]\sin \theta=\pm \sqrt{\dfrac{17}{49}}[/tex]
[tex]\sin \theta=\pm \dfrac{\sqrt{17}}{7}[/tex]
The given value of [tex]\sin \theta[/tex] is positive. So, [tex]\sin \theta= \dfrac{\sqrt{17}}{7}[/tex].
Therefore, the value of value [tex]\sin \theta[/tex] is [tex]\sin \theta= \dfrac{\sqrt{17}}{7}[/tex].

Evaluate the exponential expression. 14^2
Answer:196
Step-by-step explanation:
Answer:
196
Step-by-step explanation:
Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor. So in the case of 32, it can be written as 2 × 2 × 2 × 2 × 2=25, where 2 is the “base” and 5 is the “exponent”. We read this expression as “two to the fifth power”.
