first you would need to multiply the total by .25(the decimal form of 25%) which will give you 86.3075. Then add it back to 354.23, which will give you 431.5375. rounded to the nearest hundredth would be 431.54
F(x)=-2x+2 find f(6)
Answer:
(6,-10)
Step-by-step explanation:
(-2*6)+2=-10, and the 6 is the X value, the -10 is the Y value.
Answer:
f(6) = -10
Step-by-step explanation:
Plug in 6 for x in the given equation:
f(x) = -2x + 2
f(6) = -2(6) + 2
Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, multiply. Note that when you are multiplying one negative number and one positive number together, your answer will be negative:
f(6) = -2(6) + 2
f(6) = (-2 * 6) + 2
f(6) = (-12) + 2
Next, simplify. Subtract:
f(6) = -12 + 2
f(6) = -10
-10 is your answer when f(6).

A flower shop ordered a shipment of red, blue, and white flowers. The ratio of red: blue: white flowers in the shipment is 3: 1: 2.There are 60 white flowers in the shipment. How many flowers are in the shipment.
A.120 flowers
B.180 flowers
C.240 flowers
D..360 flowers
Answer: A
Step-by-step explanation: this is to easy
The total number of flowers in shipment is 180.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
The ratio of flowers,
red: blue: white = 3:1:2
Let red flowers are 3x,
Red flowers are x,
and white flower are 2x.
Therefore, total number of flowers = 3x+x+2x = 6x
Given that,
The total number of white flowers = 60
⇒2x = 60
x = 30
Total number of flowers = 6x = 6×30 = 180
There are 180 flowers in the shipment.

Of the 40 randomly chosen students surveyed, 27 are involved in extracurricular activities at school. There are 680 students at the school. Predict the number of students in the school who are involved in after-school activities. (Please answer the right answer and how you got the answer)
Answer:
It's around 459. So 460 if need to round
Step-by-step explanation:
So, 40 randomly chosen people do not represent the whole school, but using the ratio 27:40 you are given in the equation, you can divide the number of students (680) by the surveyed students (40) to get 17. What this means is there is 17 groups of 40 in the school, so to distribute the amount of people who are in a after-school activity, you must multiply 17 x 27 to get the assumption of about 459 kids. Hopefully you understand =)

A company has two manufacturing plants with daily production levels of 7x+19 items and 5x−2 items, respectively. The first plant produces how many more items daily than the second plant?
Answer:
The first plant manufactures 2x + 21 more items daily.
Step-by-step explanation:
Given that:
Production level of plant one = 7x + 19
Production level of plant two = 5x -2
To find the number of items first plant manufactures more than second plant, we will find the difference between production levels.
Difference = (7x + 19) - (5x - 2)
Difference = 7x + 19 - 5x + 2
Difference = 2x + 21
Hence,
The first plant manufactures 2x + 21 more items daily.

A blueprint of a house shows a wall that is 5 inches long.
The blue pretty strong to a scale of 1:60.
To find:
The actual width of the wall in the house.
Solution:
The blue pretty strong to a scale of 1:60.
It means, the dimensions of blueprint to the actual house is 1:60.
Width of a wall in blue print = 5
Let the actual width of the wall in the house be x.
[tex]\dfrac{5}{x}=\dfrac{1}{60}[/tex]

1.Given the lines shown here, what are two possible equations for this system of equations
2.How many solutions does this system have?
Answer:
Two possible equations:
[tex]y = x + 1\\y = x - 5\\[/tex]
The system has 0 solution as parallel lines never cross each other.
Step-by-step explanation:
Considering the two lines are parallel, they both have the same slope.
let m be the slope of the two lines:
[tex]y = mx + y_{0}\\y=mx+y_{1}[/tex]
[tex]y_{0}, y_{1}[/tex] are the value on y axis where the two lines cross the axis.
Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.

Find the following, giving your answers to 1 decimal place?
Answer:
I. Volume = 301.6 cm³ (to 1d.p)
II. CSA = 188.5 cm² (to 1d.p)
Step-by-step explanation:
Given the following data;
Height, h = 8cm
Radius, r = 6cm
Curved length = 10cm
a. To find the volume of the cone
[tex] V = \frac{1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of the cone.r is the radius of the base of the cone.h is the height of the cone.Substituting into the equation, we have;
[tex] Volume = \frac{1}{3} * 3.142*6^{2}*8 [/tex]
[tex] Volume = \frac{1}{3} * 3.142*36*8 [/tex]
[tex] Volume = 3.142*12*8 [/tex]
Volume = 301.6 cm³ (to 1d.p)
b. The curved surface area of the cone
[tex] CSA = \pi rl[/tex]
Where;
CSA is the curved surface area of the cone.r is the radius of the base of the cone.l is the curved length of the cone.Substituting into the equation, we have;
[tex] CSA = 3.142*6*10 [/tex]
CSA = 188.5 cm² (to 1d.p)
