How many soultions does the equation 2(p+5) = 4 - 10p have? Explain how you found your answer.
Answer:
1, p = -0.5
Step-by-step explanation:
2(p+5) = 4 - 10p
2p+10 = 4 - 10p
2p + 10p = 4 - 10
12p = -6
p = -6/12
p = -0.5
2(-0.5+5) = 4 - 10(-0.5)
-1 + 10 = 4 + 5
9 = 9
lines p and q line in the coordinate plane. An equation for line p is y=0.36x-600. The slope of line q is 0.2 less than the slope of line p. what is the slope of line q?
Answer:
y = -1/3x -3
Step-by-step explanation:
Lines
Perpendicular lines have negative reciprocal slopes. To find the line, convert the slope of q and substitute it with (6, -5) into point-slope form.
y = 3x + 5 is q. It has a slope of 3. So, p will have a slope of -1/3.
y - y1 = m ( x - x1)
y - (-5) = -1/3 ( x - 6)
y + 5 = - 1/3x + 2
y = -1/3x - 3

The line plot below shows the weight of each of 15 ostrich eggs . What is the total weight of the 3 heaviest eggs
Answer:
D). 6 3/4
Step-by-step explanation:
Given,
The three eggs with the heaviest weights are;
[tex]2\frac{1}{2}[/tex] ounces
[tex]2\frac{1}{4}[/tex] ounces, &
2 ounces
To find,
The total weight of the three heaviest eggs = [tex]2\frac{1}{2}[/tex] ounces + [tex]2\frac{1}{4}[/tex] ounces + 2 ounces
= 5/2 + 9/4 + 2/1
Taking the L.C.M. of 2, 4, and 1,
= 10/4 + 9/4 + 8/4
= (10 + 9 + 8)/4
= 27/4 or 6 3/4

Each salad contains red beans, Lima beans, and black eyed beans. Use the information below to determine how many of each of the three types of beans are needed
Answer:
A.) Black eyed beans = at least 3 ; Red beans = atleast 4 ; Lima beans = atleast 5
B.) Red and Lima beans = 5 each ; Black eyed beans = 8
C.) Lima beans = 4 ; Black eyed beans = 2 ; Red beans = 2
Step-by-step explanation:
Let :
Black eyed beans = x
Red beans = x + 1
Lima beans = x + 1 +1 = x + 2
Total beans is atleast 12
x + (x +1) + (x + 2) ≥ 12
x + x + 1 + x + 2 ≥ 12
3x + 3 ≥ 12
3x ≥ 9
x ≥ 3
Black eyed beans = at least 3
Red beans = atleast 4
Lima beans = atleast 5
B.)
Same number of Red and Lima beans
Black eyed beans is 3 more than red beans
Total beans = 18
Red and Lima = x + x
Black eyed beans = x + 3
x + x + x + 3 = 18
3x + 3 = 18
3x = 18 - 3
3x = 15
x = 5
Red and Lima beans = 5 each
Black eyed beans = 3 + 5 = 8
C.)
Total beans in salad = x
Number of red beans = 2
Lima beans = 2 * 2 = 4
Lima beans = 1/2 of x ; x/2
4 = x /2
8 = x = total beans in salad
Red + lima + black eyed = 8
2 + 4 + black-eyed = 8
Black eyed beans = 8 - 6 = 2
Lima beans = 4
Black eyed beans = 2
Red beans = 2

Step-by-step explanation:
It is said that happy and healthy workers are efficient and productive. A company that manufactures exercising machines wanted to know the percentage of large companies that provide on-site health club facilities. A sample of 240 such companies showed that 99 of them provide such facilities on site.
Construct a 98% confidence interval for the percentage of all such companies that provide such facilities on site. What is the margin of error for this estimate?
Answer:
Confidence interval is 0.7 ≤ p ≤ 0.8
The margin of error is 7.1 %
Step-by-step explanation:
We have to calculate a 98% confidence interval for the proportion.
The sample proportion is p=0.75.
The standard error of the proportion is:
Here we have, the proportion or point estimate given by
= 150/200 = 0.75
Sample size, n = 200
The formula for confidence interval, CI, given a proportion, is;
At 98% z = ±2.326348
Plugging in the values of, , z and n we get;
CI = 0.6787704 ≤ p ≤ 0.8212296
To one decimal place, we have
CI = 0.7 ≤ p ≤ 0.8

Step-by-step explanation:
There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{x} =\frac{sin(10^{o})}{94}[/tex] ⇒ [tex]\frac{x}{sin(90^{o})} =\frac{94}{sin(10^{o})}[/tex] ⇒ [tex]x = \frac{94*sin(90^{o})}{sin(10^o)}[/tex] ⇒ [tex]x=541.3ft.[/tex]

Jamie bought medicine priced at $180 she had to pay 5% sales tax and an additional 1.5% for handling fee how much money did she spend
Answer:
$191.70
Step-by-step explanation:
total amount spent = cost of medicine + cost of tax + cost of shipping
cost of tax = 0.05 x $180 = $9
cost of shipping 0.015 x $180 = $2.70
total cost = $180 + $9 + 2.70 = $191.70
