Rewrite 18m - ( 2 + 3m ) without parentheses.
Answer:
15m−2
Step-by-step explanation:
Distribute the Negative Sign:
=18m + −1(2 + 3m)
=18m + (−1)(2) + −1(3m)
=18m + −2 + −3m
Combine Like Terms:
=18m + −2 + −3m
=(18m + −3m) + (−2)
=15m + −2

Suppose a lab need to need to make 400 liters of 39% acid solution, but the only solutions available to the lab are 20% acid and 50% acid. What system of equation can be used to find the number of liters of each solution the should be mixed to make the 39% solution? Let c represent the number of liters of 20% acid solution and let d represent the number of liters of 50% acid solution.
Answer:
c + d = 400
0.2c + 0.5d = 156
Step-by-step explanation:
Let
c = number of liters of 20% acid solution
d = number of liters of 50% acid solution.
c + d = 400 (1)
0.2c + 0.5d = 400(0.39)
0.2c + 0.5d = 156 (2)
From (1)
c = 400 - d
Substitute c = 400 - d into (2)
0.2c + 0.5d = 156 (2)
0.2(400 - d) + 0.5d = 156
80 - 0.2d + 0.5d = 156
- 0.2d + 0.5d = 156 - 80
0.3d = 76
d = 76/0.3
d = 253.33 liters
Substitute d = 253.33 into (1)
c + d = 400
c + 253.33 = 400
c = 400 - 253.33
c = 146.67 liters

A holiday decoration involves blue and white lights.The ratio of blue lights to white lights is 3 to 2 . The box the decoration came in stated that the number of blue lights was 114 but didn't give the number of white lights or the total number of lights.
Answer:
a. 76 b. 190
Step-by-step explanation:
a. Number of white lights
Since the ratio of blue lights to white lights is 3 to 2 and the number of blue lights is 114, it follows that 3 : 2 = 114 : x where x is the number of white lights.
So, 3/2 = 114/x
cross-multiplying,
3x = 114 × 2
3x = 228
x = 228/3
x = 76
b. Total number of lights
So, the total number of lights is thus number of blue lights + number of white lights = 114 + 76 = 190

Shop-owner Anatole is selling his sweaters for 45.96, but tries to bargain with you and tells you he will take 20% off his price if you buy it from him. Shop-owner Sergei is also selling sweaters and tells you he will sell you a sweater for 25% off of his regular price of 46.78 if you buy it from him. How much will you save if you take the better deal? Support your answer by comparing both sale prices
Answer:
How much will you save if you take the better deal?
Antole Store discount: $ 45.96 x 20% = $ 9.99
Sergei Store Discount: $ 46.75 x 25% = $ 11.69
If you buy at a Sergei store, you get a discount on your payout compared to an Antole store of $ 1.7
Step-by-step explanation:
2 times 2 times 9 times 30045
1,081,620
2 x 2 is 4
9 x 30045 is 270,405
so 4 x 270,405 is 1,081,620
How many expressions can you find using and that have a value of 12 a=6 b=4 c=-2
Answer:
Step-by-step explanation:
Some of the expressions that can be derived that have the values of 12 are:
i. 2a = 2 x 6
= 12
ii. 3b = 3 x 4
= 12
iii. (b + c) x a = (4 - 2) x 6
= 2 x 6
= 12
iv. 2b + [tex]c^{2}[/tex] = (2 x 4) + (-2 x -2)
= 8 + 4
= 12
v. [tex]b^{2}[/tex] - [tex]c^{2}[/tex] = (4 x 4) - (-2 x -2)
= 16 - 4
= 12
vi. [tex]c^{4}[/tex] - b = (-2 x -2 x -2 x -2) + 4
= 16 - 4
= 12

Answer:
y = 2[tex]\sqrt{5}[/tex], if you plug into expressions for angles K and J they equal 80°
Step-by-step explanation:
from notations given it appears that ΔFKH is similar to ΔIJG, which means their angles are congruent
therefore, we can say that 4y² = 6y² - 40
-2y² = -40
y² = 20
y = √20 or 2√5
to find the measure in degrees, plug 2√5 into each expression:
4 · (2√5)² = 4 · 4 ·5 = 80°
6 · (2√5)² = (6 · 4 ·5) - 40 = 80°

Answer:
21.25
Step-by-step explanation:
The sum of all angles in a triangle equals 180°
Since it's an isosceles triangle, the base angles are congruent.
180 = 75 + (2x + 10) + (2x + 10)
180 = 95 + 4x
-95 -95
85 = 4x
x = 21.25

Help! It’s geometry: finding angles measures between intersecting lines
Answer:
x=17
Step-by-step explanation:
So first we know that vertical angles are equal
And for the first part we have a 73 and x
So 73+x=90 Becuase in this situation if you add them up its gonna give you a right angle
you’ll get 17
SO 17 is X

A manufacturing plant is capable of producing 10 tons of product per day when it runs three shifts with no breakdowns and plenty of raw materials. Over the past week, the plant has produced an average of 7.3 tons per day because the third shift has devoted much of their time to preventive maintenance. What is the utilization of the plant?
Answer: 73%
Step-by-step explanation:
The plant is capable of producing 10 tons of product in one day.
Currently however, it is only able to produce 7.3 tons per day.
Utilization is therefore:
= Actual production/ Potential production * 100
= 7.3/10 * 100
= 73%

The area of a ferris wheel is about 154 square meters. Which of the following is closest to the length of one of the spokes? [Assume
the spokes go from the center to the edge of the ferris wheel. Use 3.14 for T.]
Acircle = 12
A. 49 m
B. 6 m
C. 7m
D.14 m
Answer:
The length of one of the spoke is 7 m
Option C is correct answer.
Step-by-step explanation:
Area of Ferris Wheel = 154 square meters.
We need to find the length of one of the spokes.
We are given: Assume the spokes go from the centre to the edge of the Ferris wheel.
So, We are given area of circle and we need to find radius of circle.
The formula used is: [tex]Area\:of\:circle=\pi \:r^2[/tex]
Putting values and finding radius
[tex]Area\:of\:circle=\pi \:r^2\\154=3.14\:r^2\\r^2=\frac{154}{3.14}\\r^2=49\\Taking\:square\;root\\\sqrt{r^2}=\sqrt{49}\\r=7\:m[/tex]
So, Radius of circle = 7 m
The length of one of the spoke is 7 m
Option C is correct answer.

Answer:
The interest is: $2550.00
Step-by-step explanation:
I = P x r x t
P is the principal amount, $12000.00.
r is the interest rate, 4.25% per year, or in decimal form, 4.25/100=0.0425.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 12000 × 0.0425 × 5 to get that:
The interest is: $2550.00
