HURYY I NEED THIS BEFORE 3 !!What is the equation of the line that passes through the point (16.-7) and has slope of m= -3/4 written in point-slope form?
Answer:
The answer is
[tex] \huge y + 7 = - \frac{3}{4} (x - 16) \\ [/tex]
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question we have the final answer as
[tex]y + 7 = - \frac{3}{4} (x - 16)[/tex]

What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
a(b + c) = a x b + a x c
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
Also This property is known by distributive law and applies to subtraction also.
The Distributive Property be used to find 7 x 391;
7 x 391 = (7 x 300) + (7x 90) + (7 x 1)

Intravenous fluid bags are filled by an automated filling machine. Assume that the fill volumes of the bags are independent, normal random variables with a standard deviation of 0.08 fluid ounces. (a)What is the standard deviation of the average fill volume of 22 bags
Answer:
0.017
Step-by-step explanation:
Given that:
Population standard deviation (σ) = 0.08
Standard deviation of the average fill volume of 22 bags :
The standard deviation of sample means = standard error ; defined as ;
SE = σ / √n
SE = 0.08 / √22
SE = 0.08 / 4.6904
SE = 0.0170560
SE = 0.017
Without multiplying, how can you tell which product will be greater, 4 × 3 or 4 × 5? Explain.
Answer:
4 times 5
Step-by-step explanation:
You can tell because when multiplying 4x5 you are using larger numbers.
Product of 4×5 will be greater as 5 is greater than 3.

HELP PLEASE GOD I HAVE A DAY HELP!!!!) A daycare employee earns $10.90 per hour for the first 40 hours he works in 1 week. He is paid 1.5 times that rate for each additional hour that he works. How much money does he earn working for 43 hours in 1 week?
Answer:
$485.05 per week of 43 hours labor
Step-by-step explanation:
First of all, we already know that he works the first 40 hours, so:
$10.90*40= $436
Now it says the next three hours are 1.5* the original pay;
$10.90*1.5= $16.32 (x 3 because thats the extra hours)
$16.32*3 = $49.05
Now, we add the numbers:
$436+$49.05= $485.05

Answer:
The conversion factor to convert cups to liters is 0.237
Step-by-step explanation:
Given : A table showing conversions for common units of capacity.
Units of capacity
Customary System Units Metric System Units
1 gallon 3.79 liters
1 quart 0.95 liters
1 pint 0.473 liters
1 cup 0.237 liters
We have to find the conversion factor to convert cups to liters.
Consider the given table.
Since, given One cup is equal to 0.237 liters.
So , the conversion factor to convert cups to liters is 0.237
For example to convert 10 cups to liters, we can multiply the number of cups by 0.237 to get cups in liters.
That is 10 cup = 10 × 0.237 = 2.37 liters.
Thus, 10 cups is equal to 2.37 liters.
Hence, The conversion factor to convert cups to liters is 0.237

A man and a woman start from the same point. The man walks S60°E at 1.3 m/sec. The woman
walks south at 1.6 m/sec. At what rate is the distance between the man and woman changing
after 35 minutes?
Answer:
The distance between the man and woman is changing at the rate of 1.5 m/sec.
Step-by-step explanation:
Speed = [tex]\frac{distance}{time}[/tex]
⇒ distance = speed x time
After 35 minutes (2100 seconds) ,
the man has walked a distance = 1.3 x 2100
= 2730 m
After 35 minutes, the woman has walked a distance = 1.6 x 2100
= 3360 m
The sketch of the displacement of the man and woman forms a triangle with an included angle. Applying the cosine rule, we have:
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2abCos θ
= [tex]3360^{2}[/tex] + [tex]2730^{2}[/tex] - 2 x 3360 x 2730 x Cos [tex]60^{o}[/tex]
= 11289600 + 7452900 - 18345600(0.5)
= 18742500 - 9172800
= 9569700
c = [tex]\sqrt{9569700}[/tex]
= 3093.5 m
The distance between the man and woman at 35 minutes is 3093.5 m.
The distance between the man and woman is changing at the rate = [tex]\frac{3093.5}{2100}[/tex]
= 1.4731
= 1.5 m/sec
The distance between the man and woman is changing at the rate of 1.5 m/sec.

What is an equation of the line that passes through the point (-5,7) and is parallel
to the line 3 - 5y = 15?
Answer
y=0x+7
Step-by-step explanation:
Parallel lines share the same slope, to solve, you need to find the slope of the line it is parallel to.
3-5y=15, since this equation has no x value, that basically means that the slope is 0.
Since the slope is 0 and you have an ordered pair, you can now substitute the ordered pair and the slope into slope intercept form to solve for 'b' or the y intercept.
y=mx+b
(-5,7)
7=0(-5)+b
b=7
y=0x+7
