26 - 44 : 11 - 5*2- 2*(14:7) =
Answer: 4
Step-by-step explanation:
Follow the PEMDAS so the first thing you do is 14:7 which is 2. then you do the division and multiplication so the 44:11 is 4, 5*2 is 10, and 2*2 is 4. The next thing you do is addition and subtraction. 26-4-4-10-4 is 4. So, the answer is 4.

The volume of the shaded portion of the cylinder help??????????????
Answer:
56.52mm²
Step-by-step explanation:
Based on observation, sum of diameters of small circles = diameter of the big circle.
In question, diameter of big circle = 12 mm.
And radius of big circle = 12mm/2 = 6mm
Let the diameter of each small circle be '2a'. So, radius of each small = 2a/2 = a.
=> 2a + 2a = 12mm
=> 4a = 12mm
=> a = 3mm
=> radius of each small circle = 3mm
Area of big circle = πr²
= (3.14)(6mm)²
= 113.04 mm²
Area covered by 2 small circles is: 2 * area of 1 one circle.
=> 2 * π(3mm)² = 18π mm²
=> 56.52 mm²
Shaded area = total area - area of 2 circles = 113.04 - 56.52 mm² = 56.52 mm²
what is 22.8333333333 as a fraction?
Answer:
22 83/100
Step-by-step explanation:
22 is a whole number, while .8333 is continues you have to round it to .83. .83 is in the hundredths place so it would be 83/110. So in the end you'll have 22 83/100
Answer: I’m assuming this is supposed to repeat because that’s ridiculous if it isn’t. The answer is 22 5/6

The linear function y=2x+28 models the average cost of a haircut in a certain city, where y, is the average price of a haircut x years after 2000. Find the slope for the model. Then describe what this means in terms of the unit rate of change in the average cost of a haircut over time.
Answer:
The slope of the model is [tex]m = 2\,\frac{USD}{yr}[/tex].
The value of the slope indicates that the average cost of a hair cut is increased by 2 US dollars each year.
Step-by-step explanation:
We have to notice that given function is a linear function, that is, a first order polynomial, whose standard form is described below:
[tex]y =m\cdot x + b[/tex]
Where:
[tex]m[/tex] - Slope, dimensionless.
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]b[/tex] - y-Intercept, dimensionless.
In this case, we use the linear function [tex]y = 2\cdot x + 28[/tex], where [tex]x[/tex] is the time after 2000, measured in years, and [tex]y[/tex] is the average cost of a hair cut. The slope of the model is [tex]m = 2\,\frac{USD}{yr}[/tex].
The value of the slope indicates that the average cost of a hair cut is increased by 2 US dollars each year.

what is the solution for y=2x-1
Answer:
Simplifying
Y = 2x + -1
Reorder the terms:
Y = -1 + 2x
Solving
Y = -1 + 2x
Solving for variable 'Y'.
Move all terms containing Y to the left, all other terms to the right.
AnswerY = -1 + 2xStep-by-step explanation:
Identify the statement(s) that are both biconditional and false. Three points are not in the same plane if and only if exactly one line passes through them. Exactly one line passes through three points if the points are in an infinite number of planes. an infinite number of planes pass through the same three points if and only if the points are not on the same line. three points on the same line if and only if exactly one plane passes through them.
Answer:
Step-by-step explanation:
1) Three points are not in the same plane if and only if exactly one line passes through them.
It is biconditional and false because more than one plane can pass through three points
2)Exactly one line passes through three points if the points are in an infinite number of planes.
It is biconditional and true because three points on same line will be in more than one plane and if they are not in the same plane then connect them and it will form a triangle which is in only one plane
3). an infinite number of planes pass through the same three points if and only if the points are not on the same line.
It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them
4). three points on the same line if and only if exactly one plane passes through them.
It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them
5) A cellphone company charges a monthly fee of $34.00, plus $0.05 per text message. If you have at most $52 to spend, how many text messages can you send?
Answer:
At most you can send 360 text messages while spending at most $52.
Step-by-step explanation:
Let x = money per text message
34.00 + 0.05x ≤ 52
-34.00 -34.00
[tex]\frac{ 0.05x}{ 0.05}[/tex] ≤ [tex]\frac{18}{0.05}[/tex] = 360
So, at most you can send 360 text messages while spending at most $52.
Answer:
360

what is the most accurate reading seconds as indicated by the long second hand?
1st answer: 5.3s
2nd answer: Tenths of seconds
Answer:
r = 0.84
Step-by-step explanation:
The mean reading time obtained with the stopwatch measurements was 4.34 ± 0.57 seconds (196.21 ± 21.79 wpm), versus 4.44 ± 0.59 seconds (192.24 ± 22.20 wpm) by computer measurement (r = 0.84).
For his science fair project, Ernesto is investigating the water quality in his school's water fountains. He finds that the water is safe to drink; a 50-milliliter water sample has just 13 milligrams of dissolved solids. If Ernesto fills a 2-liter bottle from one of the water fountains at his school, how many grams of dissolved solids would his bottle have?
Answer:
0.52grams of dissolved solids.
Step-by-step explanation:
; a 50-milliliter water sample has just 13 milligrams of dissolved solids. If Ernesto fills a 2-liter bottle from one of the water fountains at his school, how many grams of dissolved solids would his bottle have
50ml = 13mg of dissolved solids
1 litre = 1000 millilitres
2 liter = 2 × 1000 = 2000millilitres
50ml = 13mg
2000ml =
Cross Multiply
2000ml × 13m/50ml
= 520mg of dissolved solids.
We are to convert our final answer to grams
= 1 milligram = 0.001 gram
520 milligram =
520 mg × 0.001g/1 mg
= 0.52 grams of dissolved solids
Triangles RST and XYZ are shown at right. Emma knows
ZTELZ. She claims that triangles RST and XYZ are congruent. As part of her
reasoning, which theorem could she use? Select two that apply.
Answer:
Step-by-step explanation:
Given :-
TR = ZXSR = YXTo Prove :-
ΔRST ≅ ΔXYZSolving :-
TR = ZX (Given)SR = YX (Given)∠R = ∠X (Angle that lies between equal sides of respective parts of the triangle)ΔRST ≅ ΔXYZ (1,2,3, SAS congruence)here, what do we do if it says y=-x or y=x
You plot the points on the graph first with a pencil. Draw the given line, in this case, it's y=-x.
From a point, you do rise and run to the line and reverse it on the other side of the line to get the points.

You cant see the equation
Step-by-step explanation:
Solve the following system of equations using substitution, show all steps. 2x-4y=20 / x= 4
Answer:
(4, -3)
Step-by-step explanation:
Since we know that X = 4, when can set X = 4 in the other equation in order to solve for Y
2x - 4y = 20
2(4) - 4y = 20
8 - 4y = 20
-8 -8
-4y = 12
-4y/-4 = 12/-4
y = -3
Since we already know X = 4, the intersection point or solution to the System is (4, -3)

Answer:
[tex]m = \frac{-1}{6}[/tex]
Step-by-step explanation:
You are solving for the slope (m). Use the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) =(-2 , 1)\\(x_2 , y_2) = (4 , 0)[/tex]
Plug in the corresponding numbers to the corresponding terms:
m = [tex]\frac{0 - 1}{4 - (-2)}[/tex]
[tex]m = \frac{-1}{4 + 2} \\m = \frac{-1}{6}[/tex]
[tex]m = \frac{-1}{6}[/tex] is your answer.
