Answer:
Home 30, visitor 17.
Step-by-step explanation:
Visiting team score is x. Home score is then x+13. Total of both is 47 so...
x+(x+13)=47
2x+13=47
2x-34
x=17
x+13=30
The score of Home Team is 30 points.
The score of Visiting team is 17 points.
Here,
During the last schools football game, the Home Team scored 13 more points than the Visiting team.
The total of their scores was 47.
We have to find points of each team score.
What is Number system?
A number system is a system representing numbers. It is also called the system of numeration.
Now,
Let Visiting team score x points.
Then, Home team score is 13 more points than the Visiting team.
Home team score x + 13 points.
The total of their scores was 47.
Hence,
x + (x + 13) = 47
2x + 13 = 47
2x = 47 - 13
2x = 34
x = 17
So, The score of Visiting team is 17 points.
And, The score of Home Team = 17 + 13 = 30 points.

Step-by-step explanation:
A water tank contains 320 litres of water, correct to the nearest 10 litres. 50 litres of water, correct to the nearest litre, are removed from the tank. Calculate the upper bound of the amount of water left in the tank.
Answer:
[tex]N_l=270 litres[/tex]
Step-by-step explanation:
From the question we are told
Total litres of water [tex]N_t=320[/tex]
Total litres removed [tex]N_r=50[/tex]
Generally the Total litres left in the tank N_l is mathematically given as
[tex]N_l=N_t-N_r[/tex]
[tex]N_l=320-50[/tex]
[tex]N_l=270 litres[/tex]
Therefore the total water left in the tank is
[tex]N_l=270 litres[/tex]
A ball is thrown into the air from a height of 4 feet at time t=0. The function that models this situation is h(t)=-16t^2+63t+4. What will be the height of the ball after 2 seconds?
Answer:
66 feet
Step-by-step explanation:
We know that the t in the equation represents the time. So, substitute 2 for the t in the function and simplify to find the height after 2 seconds:
[tex]h(t) = -16t^2+63t+4\\h(2) = -16(2)^2+63(2)+4\\h(2) = -16(4)+126+4\\h(2) = -64 + 126+4\\h(2) = 66[/tex]
Thus, the height would be 66 feet.
Use addition to solve the system of linear equations. Include all of your work in your final answer.
Answer: No solutions
Step-by-step explanation:
You can either use substitution or elimination
You can plug in y to the first equation to get x-(x-4)=6 to get 4=6 which is not possible so no solutions
Find the measure of FG.
Can someone help??
Answer:
28
Step-by-step explanation:
Side FG = Side DG. Therefore, 5x - 17 = 3x + 1, or 2x = 18, or x = 9.
If x = 0 then the length of side FG is 5(9) = 17, or 28.
If the angles are represented in degrees, find both angles:
cos(8x+18)=sin(−2x+36)
Answer:
24 and 66degrees
Step-by-step explanation:
Given the equation
cos(8x+18)=sin(−2x+36)
In trigonometry identity, cos theta = sin (90- theta)
The given expression becomes;
sin (90 - (8x+18)) = sin(−2x+36)
sin will cancel out to have;
90 - (8x+18) = (−2x+36)
90-8x-18 = -2x+36
-8x +72 = -2x+36
-8x + 2x = 36 - 72
-6x = -36
x = 36/6
x = 6
Hence the value of x is 6
cos(8x+18) = cos(8(6)+18)
= cos 66
Also
sin(−2x+36)
= sin(−2(6)+36)
= sin(−12+36)
= sin 24
Hence both angles are 24 and 66degrees
Which expressions are equivalent to 12a+24b? Select all that apply. 10(2a+14b) 2(6a+4b) 6(2a+4b) 3(4a+8b)
Answer:
3(4a+8b)
Step-by-step explanation:
12a + 24b
= The common multiple between 12 and 24 is 3
3(4a + 8b)
Hence the expression which is equivalent to 12a + 24b is 3(4a+8b)
For a circle of radius 4 feet, find the arc lengeth, S subtened by a central angle of 26 degrees
Answer:
Exact answer = 26π/45 feet.
or we can write it as 1.815 feet to the nearest thousandth.
Step-by-step explanation:
The circumference of the circle = 2*4*π = 8π feet.
So the length of S = (26/360) * 8π
= 26π/45 feet.

HOPE IT CAN HELP U : )Why is x = 6 a solution to the proportion 192/36 = 32/x ?
Because if 192/36 = 5.3333 and 32/6 = 5.3333 then the solution is right
Answer:
It is a solution because when you divide 192 by 36 you get 5 and one third. When you divide 32 by 6 you also get 5 and one third. This means they are equal.

Step-by-step explanation:
Im only a freshman, but i think i got it, i just assumed that the other small part at the bottom was also 20 degrees, which would mean that you are missing the 140 degrees from the 180 degree line
Answer:
120 degrees
Step-by-step explanation:
The bottom part is 40 degrees,
the two lines are parallel, so theoretically, you can just put them together. Then using vertical angles, you can tell it's 40 degrees.
40 + 20 = 60
180-60 degrees is 120 degrees.

Richmond High School has 1900 students and is shrinking by 15 students per year. Write a rule that represents the population at Richmond High School. Let x represent years and y represent population.
Answer:
y = -15x + 1900
Step-by-step explanation:
This is correct because, your base number is 1500, so that is your y-intercept. The school's population is shrinking by 15 students per year so, that becomes your slope. Hope I helped. ;)
