Answer:
x + y = 35 equation 1
x + 2y = 62 equation 2
He made 8 1 point free throw
He made 27 2 point field goal
Step-by-step explanation:
let x = 1 point free throw
y = 2 point field goal
two equations can be derived from the question
x + y = 35 equation 1
x + 2y = 62 equation 2
Subtract equation 1 from 2
y = 27
Substitute for x in equation 1
x = 35 - 27 = 8
He made 8 1 point free throw
He made 27 2 point field goal

About how much cardboard is needed to make the inner tube for a roll of paper if the
tube has a diameter of 4.5 cm and is 24 cm long?
Answer:
[tex]A=339.42\ cm^2[/tex]
Step-by-step explanation:
The diameter of the roll of paper, d = 4.5 cm
Radius, r = 2.25 cm
Height of the roll of papaer, h = 24 cm
We need to find how much is needed to make the inner tube for a roll of paper. The surface area of a cylinder for inner tube is given by :
[tex]A=2\pi r h\\\\=2\times \dfrac{22}{7}\times 2.25\times 24\\\\=339.42\ cm^2[/tex]
So, the required area is [tex]339.42\ cm^2[/tex].

20. A construction company is hired to resurface a straight section of road.
• The section is 100 yards long and 18 feet wide.
• The company's truck can haul 250 cubic feet of gravel per load.
What is the minimum number of truckloads required to completely cover the section of
road to a depth of 6 inches?
A 3
B. 4
C.
10
D. 11
Answer:D
Step-by-step explanation:
Convert 100 yards to feet, which becomes 300 feet.
6 inches into feet, 0.5 feet.
18 feet times 300 feet times 0.5 feet is 2700 cubic feet.
Divide 2700 by 250 and you get 10.8. Meaning, you need 11 trucks since there is a remaining 0.8.
The minimum number of truckloads required to completely cover the section of road to a depth of 6 inches should be 11.
Calculation of the minimum number:Since
The section is 100 yards long and 18 feet wide. The company's truck can haul 250 cubic feet of gravel per load.
So here first we have to convert 100 yards to feet so it should be 300 feet.
Now 6 inches into feet should be 0.5 feet
Now the total be like
= [tex]18 \times 300 \times 0.5[/tex]
= 2700
Now the minimum number should be
= [tex]2700 / 250[/tex]
= 10.8
= 11

Step-by-step explanation:
Initial co-ordinate of p = ( 2, -2)
Rule for rotation 180° about the origin
(x,y) ----> ( -x , -y )
Meaning of the rule: To find the coordinates of a point that was rotated 180° about the origin all we have to do is add negative signs in front of the x and y values of the coordinates. THE NUMBER STAYS THE SAME. THE ONLY THING THAT CHANGES IS THE SIGN
* add - to the coordinates *
- ( 2 , -2 )
-1 * 2 = -2
-1 * -2 = 2
we end up with ( -2, 2 )
Hence the answer is B
For this one a rectangle was dilated and we have to find the scale factor and the new width.
We are given the pre image width (3) and length (4) and the new image length (12)
We can find the scale factor by dividing the new image length by the pre image length ( Note that you have to use corresponding sides. Like pre image height over new image height or pre image length over new image length. etc. )
So scale factor = 12 / 4 or 3
Now to find the new image width
We can do this by multiplying the pre image width (3) by the scale factor (3)
So new image width = 3 * 3
3 * 3 = 9
Hence the width of the enlarged print is C 9 inches
For this one we need to find x using angle rules
The angles shown are supplementary angles meaning that the sum of the two angles is 180
That being said we can create an equation to solve for x
180 = 64 + 4x + 16
Now we just solve using basic algebra
step 1 combine like terms
64 + 16 = 80
now we have 180 = 4x + 80
step 2 subtract 80 from each side
80 - 80 cancels out
180 - 80 = 100
now we have 100 = 4x
step 3 divide each side by 4
100/4 = 25
4x/4=x
we're left with x = 25

For a science project hailey puts a cylindrical can out to collect rain water the can was 11 inches tall and diamamter of 8 inches if it rained exactly 20 cubic inches a day how many days
Answer:
27.7 days
Step-by-step explanation:
volume of a cylinder = nr^2h
n = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 8/2
(22/7) x (4^2) x 11 == 553.14 in^3
if it rains 20 cm^3 per day, the can would fill in : volume of can / amount of rain = 553.14/20 = 27.7 days

Suppose a city with population of 400,000 has been growing at a rate of 5% per year. If this rate continues, find the population of this city in years.
The number of years value isn't given, we could use an hypothetical value, which can be substituted for the correct number of years given in your exercise in other to find the exact answer.
Using a t value of 10 years
Answer:
651558
Step-by-step explanation:
Given that:
Initial population, P0= 400,000
Growth rate, r = 5%
Using the relation :
P(t) = P0 * (1 + r)^t
t = number of years = 10
P(10) = 400000 * (1 + 0.05)^10
P(10) = 400000 * (1.05)^10
P(10) = 400000 * 1.628894626777
P(10) = 651557.8507
= 651558 nearest whole number.
Recall that, the t value used is hypothetical and should be replaces with te exact value given in your question.

Answer:
x = 36 degrees
y = 48 degrees
Step-by-step explanation:
The two given triangles are congruent
Hence, we can say that the interior angles are equal
We shall use the angle markings on each of the triangles
Using the markings, we can see that y is 48 degrees
Now, let us find the last angle measure of the first triangle
Mathematically, the sum of angles in a triangle is 180
Thus;
108 + 48 + A = 180
A = 180 - 48 - 108
A = 180 - 156 = 24
Now, the measure 2x-y is equal to this;
Hence;
2x -y = 24
2x = 24 + y
we have that y = 48
2x = 24 + 48
2x = 72
x = 72/2
x = 36 degrees

None.
All the four given measurements can form a triangle.
Step-by-step explanation:
Given;
first measurement, = 2m , 5m, 6m
second measurement, = 8m, 10m, 17m
third measurement, = 5m, 20m, 22m
fourth measurement, = 4m, 15m, 20m
For any of the three lengths to form a triangle, the sum of any two sides must be greater than the third side.
First measurement: 2m + 5m = 7m and 7m > 6m (can form a triangle)
Second measurement: 8m + 10m = 18m and 18m > 17m (can form a triangle)
Third measurement: 5m + 20m = 25m and 25m > 22m (can form a triangle)
Fourth measurement: 4m + 15m = 19m and 19m < 20m BUT
20 m + 15m = 35 m and 35 m > 4m (can form a triangle)
Therefore, all the four given measurements can form a triangle.

1. The X axis is the line going left and right
2. The Y axis is the line going up and down
3. The origin is the point where the X and Y axis meet; (0,0); by the 0
4. The points will be written as A, B, C. This is going from left to right. So the first box on the coordinate plane furthest to the left with be labeled with A. Then the second box furthest from the left; the middle box; will be labeled with B. Then the last box will be labeled C
5. (4,6)
6. (2,9)
7. (0,4)
8. When Allie identified the point, she mixed the X and Y coordinates. To identify a point you first want to find the point following the X axis. Then do the same with the Y axis. After doing this you should have 2 numbers, in which are 3 and 7. Now when writing the coordinates, the X axis ALWAYS comes first. So it should look like (7,3)
