Answer:
3p-p
Step-by-step explanation:
I always think of the negative sign out ruling the positive sign so let's do that for the -p part.
3p-p is what it becomes
Your question says simplify but just in case you want the answer here it is:
-p is also the same as -1p
So therefore we have
3p-1p
And we subtract the coefficients and keep the variable
2p would be your answer but once again I don't know if you wanted that so just to be sure I put 3p-p as my "answer".
How does the equation change if tamira has 60 dollars to spend on a mixture of almonds and cashews? How many pounds of nuts can she buy if she buys only cashews ? Only almods? A mixture of both
Answer:
Almonds cost $8 per pound and Cashews cost $10 per pound.
Assuming pounds of Almonds are denoted as a and Cashews are c, the formula will be:
8a + 10c = 60
Only Cashews:
This means that Almonds would be zero.
8(0) + 10c = 60
10c = 60
c = 60/10
c = 6 pounds of cashews
Only Almonds
8 * a + 10(0) = 60
8a = 60
a = 60/8
a = 7.5 pounds of almonds
A mixture of both.
We can use the formula above to calculate how many of each she can buy but she cannot buy more than 7.5 almonds or more than 6 cashews as she does not have enough money on her.
Assuming she wanted to buy 5 pounds of almonds, she would be able to buy:
8 * 5 + 10c = 60
40 + 10c = 60
10c = 60 - 40
c = 20/10
c = 2 pounds of cashews
solve the following system of equations
Answer:
x = 4
y = 8
Step-by-step explanation:
From the question given above,
3.2x – 0.6y = 8 .......... (1)
–0.8x + 0.9y = 4 ......(2)
We shall determine the value of x and y by using elimination method as illustrated below:
3.2x – 0.6y = 8 .......... (1)
–0.8x + 0.9y = 4 ......(2)
Multiply equation 1 by 0.8 and equation 2 by 3.2
0.8 × (3.2x – 0.6y = 8)
2.56x – 0.48y = 6.4 ......... (3)
3.2 × (–0.8x + 0.9y = 4)
–2.56x + 2.88y = 12.8....... (4)
Next, add equation 3 and 4 together. This is illustrated below:
,,,,,, 2.56x – 0.48y = 6.4
+ –2.56x + 2.88y = 12.8
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
2.4y = 19.2
Divide both side by 2.4
y = 19.2 / 2.4
y = 8
Substitute the value of y into any of the equation to obtain the value of x. Here, we shall use equation equation 1. This is illustrated below:
3.2x – 0.6y = 8
y = 8
3.2x – 0.6(8) = 8
3.2x – 4.8 = 8
Collect like terms
3.2x = 8 + 4.8
3.2x = 12.8
Divide both side by 3.2
x = 12.8 / 3.2
x = 4
From the calculations made above,
x = 4
y = 8

If the measure of EF is 90° , what is the arc length of EF?
Answer:
[tex]\huge\boxed{15 \pi \ \text{or} \approx 47.1 \ \text{in.}}[/tex]
Step-by-step explanation:
We can note a couple of relationships in this circle.
The arc length will be a fraction of the circumference. It will be the same fraction of the circumference that the central angle is to the entire circle.
First step: Find the circumference of the circle.
The circumference of any circle can be defined by the formula [tex]2 \pi r[/tex], where r is the radius of the circle. The radius is given to us, 30 in. We can now substitute that into the formula.
[tex]2\cdot \pi \cdot 30[/tex] [tex]60 \cdot \pi[/tex] [tex]60\pi[/tex]So our circumference is 60π.
Second Step: Find the ratio of the central angle of the arc to the total circle degrees
We know that the total amount of degrees in a circle is 360°. Therefore, we can set up a proportion to find the ratio between the central angle (90°) and the total circle measurement.
[tex]\frac{90}{360}[/tex]
Third Step: Equal out the two proportions and solve for the missing arc length
Now that we have our base proportion ([tex]\frac{90}{360}[/tex]), we can turn 60π into a proportion as well, leaving 60π as the denominator so we can solve for the arc length.
[tex]\frac{x}{60 \pi} = \frac{90}{360}[/tex]
We can now solve for x by cross multiplying.
[tex]\frac{90}{360} = \frac{1}{4}[/tex] [tex]\frac{x}{60\pi} = \frac{1}{4}[/tex] [tex]x = \frac{60\pi \cdot 1}{4}[/tex] [tex]x = \frac{60\pi}{4}[/tex] [tex]x = 15\pi \approx47.1[/tex]Hope this helped!

The equation y=19x+350 represents the relationship between the total cost, in dollars, y, to rent a banquet hall for a party, and the number of people attending, x. The y-intercept is 350 and represents the total cost to rent the banquet hall . The slope is 19 and represents the cost per person attending
Further explanation
Answer and explanation:
The equation y=19x+350 representing the total cost for the banquet hall based on number of people attending has both dependent and independent variables.
The independent variable is x which represents the number of people attending(each person costs $19) and therefore determines the total cost y which will be the cost of the banquet hall given number of people attending x
If we make an illustration with this equation, we could plug in a number of attendants x = 200 and then observe the total cost of the banquet hall y
If x=200
y=19x+350
y= 19×200+350
y= 3800+350
y= $4150
Therefore total cost of banquet hall if there are 200 guests at the banquet hall =$4150
The total cost of the banquet hall, if there are 200 guests at the banquet hall, is $4150.
Given that,
The equation y = 19x+350 represents the relationship between the total cost,
In dollars, y, to rent a banquet hall for a party, and the number of people attending, x.
The y-intercept is 350 and represents the total cost to rent the banquet hall. The slope is 19.
We have to determine,
The cost per person attending.
According to the question,
The equation y = 19x+350 representing the total cost for the banquet hall based on the number of people attending has both dependent and independent variables.
The independent variable is x which represents the number of people attending(each person costs $19).
Therefore,
To determine the total cost y which will be the cost of the banquet hall given the number of people attending x.
Then, the total cost of the banquet hall y is,
[tex]y=19x+350\\\\y= 19\times200+350\\\\y= 3800+350\\\\y= 4150[/tex]
Hence, the total cost of the banquet hall, if there are 200 guests at the banquet hall, is $4150.

Jane spends about 1/6 of the day sleeping. How many hours in a day does Jane sleep? How many hours in a week?
Answer:
Jane spend 4 hours in a day sleeping, and 28 hours in a week.
Step-by-step explanation:
In 1 day, there are 24 hours. 24 multiplied by 1/6 is 4. I know this because 24 x 1/6 = 24/1 x 1/6 = 24/6 = 4/1 = 4.
In 1 week, there are 168 hours. 1/6 multiplied by 168 is 28. I know this because 168 x 1/6 = 168/1 x 1/6 = 168/6 = 28/1 = 28

If a = 7 and b = 11, what is the measure of ∠B? (round to the nearest tenth of a degree) A) 32.5° B) 39.2° C) 50.5° D) 57.5°
Answer:
D) 57.5°
Step-by-step explanation:
As the question is not complete. So, let's suppose it is a right angle triangle then, we can apply Pythagoras theorem to calculate the hypotenuse or the third side.
Pythagoras Theorem = [tex]c^{2}[/tex] = [tex]a^{2} + b^{2}[/tex]
a = 7 and b = 11
[tex]a^{2}[/tex] = 49
[tex]b^{2}[/tex] = 121
Plugging in the values, we will get:
[tex]c^{2}[/tex] = 49 + 121
[tex]c^{2}[/tex] = 170
c = [tex]\sqrt{170}[/tex]
To calculate the unknown angle B, we can use law of sine.
Law of sine = [tex]\frac{a}{sinA}[/tex] = [tex]\frac{b}{sinB}[/tex] = [tex]\frac{c}{sinC}[/tex]
So,
[tex]\frac{c}{sinC}[/tex] = [tex]\frac{b}{sinB}[/tex]
[tex]\frac{\sqrt{170} }{sin90}[/tex] = [tex]\frac{11}{sinB}[/tex]
Sin90 = 1
sinB = [tex]\frac{11}{\sqrt{170} }[/tex]
B = [tex]sin^{-1}[/tex] ([tex]\frac{11}{\sqrt{170} }[/tex])
B = 57.5°

Cynthia invests some money in a bank which pays 5% compound interest per year.
She wants it to be worth over £8000 at the end of 3years.
What is the smallest amount to nearest pound she can invest?
Answer:
£6,910.70
Step-by-step explanation:
The computation of the amount invested is given below:
As we know that
Amount = Principal × (1 + rate of interest)^number of years
£8000 = Principal × (1 + 0.05)^3
£8000 = Principal × 1.05^3
£8000 = Principal × 1.157625
So, the principal amount is
= £8000 ÷ 1.157625
= £6,910.70

The cost per person c of chartering a tour bus
varies inversely as the number of passengers
n. If it costs $22.50 per person to charter a
bus for 20 passengers, how much will it cost
per person to charter a bus for 36 passengers?
Answer:
It will cost $12.5 per person to charter a bus for 36 passengers
Step-by-step explanation:
The cost per person c of chartering a tour bus varies inversely as the number of passengers n.
We can write:
[tex]c\:\alpha \:\frac{1}{n} \\c=\frac{k}{n}[/tex]
where k is constant of proportionality
We are given when c = 22.50, n = 20
We need to find c when n = 36
First using c = 22.50, n = 20 we will find k, the constant of proportionality
[tex]c=\frac{k}{n}\\22.50=\frac{k}{20}\\k=22.50 \times 20\\k=450[/tex]
So, we get k = 450
Now, we will find c when n = 36
[tex]c=\frac{k}{n}\\c=\frac{450}{36}\\c=12.5[/tex]
So, we get the value of c: c = 12.5
Therefore, It will cost $12.5 per person to charter a bus for 36 passengers
