Answer:
250.50 - 35m = 300 - 45.25m
Step-by-step explanation:
Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other
The equation will be 250.50 - 35m = 300 - 45.25m
The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m
Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.
Answer:
b) 250.5 – 35m = 300 – 45.25m

there are 300 window for b buildings. assuming there is an equal number of windows per building, how many windows does each building have
Answer:
[tex]300\div b[/tex] windows
Step-by-step explanation:
We can find how many windows each building has by changing our old expression.
If we assume [tex]b[/tex] is the amount of buildings and [tex]w[/tex] is the amount of windows per building, we can make the equation:
[tex]wb = 300[/tex].
Now we want to isolate w on one side.
To do this we can divide both sides by b.
[tex]wb\div b = 300\div b\\\\w = 300\div b[/tex]
So the amount of windows per building is [tex]300 \div b[/tex].
Hope this helped!

f(x) = 3x + 10
Of(x) = 2x + 3
f(x) = 4x + 5
O f(x) = 3x - 10
Answer:
f(x) = 2x +3
Step-by-step explanation:
If we assume the first point in your table is supposed to be (-7, -11), then the function exhibits a constant slope of 2.
For example, from (x, y) = (3, 9) to (4, 11) the x-value changes by 1, but the y-value changes by 2.
The only offered answer choice with a slope (x-coefficient) of 2 is ...
f(x) = 2x +3

What is equivalent to 3x-4y=6
Answer:
y= (3/4) x - (3/2)
Step-by-step explanation:
3x - 4y = 6 (using algebra add the 4y to the other side & subtract the 6 to the other side >> 3x - 6 = 4y (then divide everything by 4 to get y by itself) >> 3/4x - 6/4 = y (then simplify) >> 3/4x - 3/2 = y
What is the justification for 2y-40=-18 A the multiplication property of equality B the subtraction property C the division property D the addition property
Answer:
Addition and Division propertyStep-by-step explanation:
Addition property is used in an equation when the same value is added to both sides of the equation to simplify such equation.
Given the equation 2y-40=-18 to simplify the equation further we need to first add 40 to both sides of the equation thereby justifying the addition property as shown;
2y-40 + 40 =-18+40
2y = 40-18
2y = 22
We will also apply the division property here. Division property is used when both sides of an equation is divided by a number without affecting the equality rule.
Dividing the resulting equation by 2:
2y/2 = 22/2
y = 11
Hence the justification for the equation 2y-40=-18 are both adition and division property.
The pizza has an area of 78.5 in². What is the minimum width of a placemat that can be placed underneath it so that the pizza does not touch the table? Use 3.14 for pi.
Answer:
10 inStep-by-step explanation:
This problem bothers on the mensuration of flat shapes, circles and square.
we know that the pizza has a circular profile
and the place-mat has a square profile.
Step one:
let us solve for the radius of the pizza
[tex]area-of- pizzza= \pi r^2\\\\ 78.5= 3.142*r^2\\\\r^2= 78.5/3.142\\\\r^2= 24.98\\\\r= \sqrt{24.98} \\\\r=4.998\\\\r= 5 in[/tex]
Step two:
from inspection we know that the width of the place-mat is same as the diameter of the pizza
hence diameter of pizza
= 2r
=2*5
=10 in

During the third week of practice Ellison's cross country team ran 6 miles less than triple the number of miles they ran the
first week. If they ran m miles in practice the first week, write an expression that represents the number of miles that
the cross country team ran during the third week.
a
3-6m
3m-6
b
C
6-3m
Od
6m-3
Answer:
first week = m miles
second week = 6 miles less than triple the number of miles they ran the
first week.
Triple of the number of miles they ran the first week = 3 * m = 3m
Therefore = 3m - 6
Ray collects cars and trucks. Over the years, the number of cars he collected is 8 less than twice
the number of trucks. If he has a total of 43 cars and trucks, how many trucks does Ray have?
Answer:
Number of Trucks = 17
Step-by-step explanation:
Given:
Total number of cars and truck = 43
Find:
Number of Trucks
Computation:
Assume
Number of Trucks = x
Number of Cars = 2x - 8
Total number of cars and truck = Number of Trucks + Number of Cars
43 = x + 2x - 8
51 = 3x
x = 17
Number of Trucks = 17
A medical researcher measures the increase in heart rate of patients under a stress test. What kind of variable is the researcher studying?
The options in this question are not given; here is the complete question:
A medical researcher measures the increase in heart rate of patients under a stress test. What kind of variable is the researcher studying?
A. Identifier
B. Categorical
C. Quantitative
D. Qualitative
The answer to this question is C. Quantitative
Explanation:
In research, a quantitative variable refers to a variable or factor that involves using numbers, percentages, and in general, quantities to be understood. Moreover, this is the opposite of qualitative variables that involve using qualities. The medical research described includes a quantitative variable because heart rate can only be measured and understood through numbers. Also, other types of variables such as qualitative or categorical are not involved because these are related to qualities rather than numbers.
4 7/9 divided by 1 7/12
Answer:
2 19/5
Step-by-step explanation:
4 7/9 ÷ 1 7/12
start by turning them into improper fraction by multiplying the denominator to the whole number and adding the product to the numerator , you will get :
42/9 ÷ 17/12
42/9 * 12/17 ( reciprocal )
42/3 * 4/17 (9 and 12 can be cut smaller because both are in 3's table)
= 172/51
turn this into mixed fraction by -
Divide the numerator by the denominator.
Write down the whole number answer
Then write down any remainder above the denominator
you will get = 2 19/5
4 7/9 divided by 1 7/12 will be 3 1/57.
The first thing to do is to change the mixed fraction to improper fraction and this will be:
= 4 7/9 ÷ 1 7/12
= 43/9 ÷ 19/12
Then we change the division sign to multiplication and this will be:
= 43/9 × 12/19
We then reduce to lowest term
= 43/9 × 12/19
= 43/3 × 4/19
= 172/57
= 3 1/57
In conclusion, 4 7/9 divided by 1 7/12 is 3 1/57.

Colleen is touring an automobile plant. The tour guide tells her that they use 938 kg of aluminum to make 7 cars. All of the cars are the same so they use the same amount of aluminum for each car. If they have only used 100 kg of aluminum on the car they are building right now, how much more aluminum do they need to finish the car?
Answer:
34 kg
Step-by-step explanation:
(938/7) = 134 kg per car, so since they only have 100 kg, 34 kg are missing to complete the car.
What is the slope of the line passing through the point (2,-1) and the origin?
Answer:
y = - 1/2x
Step-by-step explanation:
if y varies directly with x and y = -12 when x = 6 find x when y = -4 A -2 B 3 C -3 D 2
Answer:
D
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 12 when x = 6, thus
- 12 = 6k ( divide both sides by 6 )
- 2 = k
y = - 2x ← equation of variation
When y = - 4, then
- 4 = - 2x ( divide both sides by - 2 )
2 = x → D
What is the total area, in square inches, of the figure shown below?
Answer:
264 in²
Step-by-step explanation:
The figure given can be divided into 5 parts as shown in the attachment below, and it would consists of the following with their dimensions:
2 triangles of the same dimensions labelled 1 and 2:
Base (b) = 16 in
Height (h) = 10 in
Area = 2*½*b*h = 2*½*16*10 = 160 in²
2 rectangles of the same dimensions labelled 4 and 5:
length (l) = 5 in
width (w) = 4 in
Area = 2(l*b) = 2(20) = 40 in²
1 rectangle labelled 3:
length (l) = 16 in
width (w) = 4 in
Area = l*w = 16*4 = 64 in²
Total area of the figure = 160 + 40 + 64 = 264 in²
Rewrite the function by completing the square.

F(x)=?(x+?)^2+?
Answer:
(x-9/2)²-25/4
Step-by-step explanation:
x² - 9x + 14
to complete the square , need to add a term (b/2)²: (-9/2)²=81/4
x² - 9x -81/4+ 14+81/4
x²-9x+81/4=(x-9/2)²
14-81/4=66-81/4=-25/4
(x-9/2)²-25/4

Step-by-step explanation:
There are 2 similar triangles in the diagram
lamppost/ lamppost's shadow/ line from end of shadow to top of lamppost
Nick/ Nick's shadow/ line from end of shadow to top of Nick
Therefore the ratios of corresponding sides are equal.
Note the shadow of the lamppost = 12 + x, thus
[tex]\frac{6}{2}[/tex] = [tex]\frac{12+x}{x}[/tex] ( cross- multiply )
6x = 2(12 + x) = 24 + 2x ( subtract2x from both sides )
4x = 24 ( divide both sides by 4 )
x = 6
Thus
Nick's shadow is 6 m long
Lamppost's shadow is 12 + 6 = 18 m long
