Answer:
He had 31 points in the first round.
Step-by-step explanation:
Answer:
39-8= 31
Step-by-step explanation:
let the first round be x
second round =8
first round + the second round = 39
therefore, x+8=39
collect like terms
x= 39-8= 31.
so the answer is 31

the equation to find how many pages Hadiza read this week.
Show your work below.
Answer: n= 15+58 = 73
Step-by-step explanation: Add pages for the week and weekend
Answer:
Step-by-step explanation:
HadizaReadingWeekly= 15 * Weekdays + 58 for Weekend
HRW=15*WD + 58
H =15*D +58
where H = HadizaReadingWeekly
D = days of the week (5)
then

determine the quadtratic that has the following square root (5/3, 7/3)
Answer:
9x^2 - 36x + 35.
Step-by-step explanation:
One would be (x - 5/3)(x - 7/3) <------ in factor form.
Getting rid of the fractions by multiplying each term by 3:
= (3x - 5)(3x - 7)
Converting to standard form
= 3x*3x -7*3x - 5*3x + 35
= 9x^2 - 36x + 35.

Please Help !! What is the volume of a cylinder with base radius 2 and height 9?
Answer:
The cylinders volume is 113.04 cubic inches
Step-by-step explanation:
The volume of a cylinder can be represented by the formula : V = π*r^2*h
So, now that we have the formula, we can simply plug in the values, and we have the volume of the cylinder.
V = π * 2^2 * 9
V = π * 4 * 9
It says to use 3.14 as π.
V = 3.14 * 4 * 9
V = 113.04
The cylinders volume is 113.04 cubic inches
Solve for x.
x=
x+19 7x+9
Hey there!
x + 19 + 7x + 9 = 180°
1x + 19 + 7x + 9 = 180°
8x + 28 = 180°
SUBTRACT 28 to BOTH SIDES
8x + 28 - 28 = 180° - 28
SIMPLIFY IT!
8x = 180 - 28
8x = 152
DIVIDE 8 to BOTH SIDES
8x/8 = 152/8
SIMPLIFY IT!
x = 152/8
x = 19
Therefore, your answer should be:
x = 19

HELP ME WITH THESE TWO QUESTIONS PLEASE.
Answer:
the answer for the first one is 141
and the answer for the second is 48
Answer:
First: -1628
Second: -16
Step-by-step explanation:
For the first problem, start by rewriting the equation by plugging in h and g as (4n-3)(-4n-4)
By FOILing this, you’ll end up with -16n^2-16n+12n+12
-16n^2-4n+12
Now you can plug in n, which is -10:
-16(10)^2-4(10)+12
-1600-40+12
-1628
For the second question, you’ll be plugging f(-2) into g, but I’ll leave -2 as n for simplicity until the end
g(n)=n^2+2n
f(n)=2n-4
g(n)=(f(n))^2+2(f(n))
(2n-4)^2+2(2n-4)
(4n^2-16n+16) + (4n-8)
4(-2)^2-16(-2)+16+4(-2)-8
16-32+16-8-8
-16
if the compound ratio of 5:8 and 3:7 is 45:x. find x
Given:
5:8 and 3:7 = 45:X
Explanation:
15:56 = 45:x
15x. = 2520
X=2520/15
x= 168
Conclusion:
Thus the value of x is found to be 168.
5:8 and 3:7=45:x
15:56 = 45:x
Product of means. = product of extremes
15x. = 2520
X=2520/15
x= 168

7 and 8 Find the measurement of the missing interior angle
Answer:
7. x = 88
8. x = 59
Step-by-step explanation:
You're probably trying to equal 180° because that's what the triangle should equal so
7. 48° + (88° - 44°) + 88° = 180°
8. 73° + (59° - 11°) + 59° = 180°

If a canoe travels 6 miles per hour downstream, and 2 miles per hour p stream, how many miles per hour will it go in still water?
Answer:
4 miles per hour
Step-by-step explanation:
The given relations allow us to write two equations.
__
The downstream speed is the sum of the canoe speed and the stream speed:
6 = c + s
The upstream speed is the difference of the canoe speed and the stream speed:
2 = c - s
Adding these two equations, we get ...
8 = 2c
4 = c . . . . . divide by 2
The canoe speed in still water is 4 miles per hour.
Answer:
4 Miles an hour

HELP ASAP PLEASE!!!!!!
Answer:
y = x/2
Step-by-step explanation:
y = -x has a negative slope so cross this one out.
y = 2x has a steeper slope that would be above the black line so cross this one out
y = 0.001x has a slope that acends very slowly so cross this one out.
y = x/2 is the best match.
Some terminology:
⇒what is the slope
⇒ is the steepness of the line
⇒calculated by dividing the rise over the run
⇒ rise is the change in the y-direction
⇒ run is the change in the x-direction
⇒look at the diagram I attached
⇒ how to find the slope in a linear equation
⇒look to the coefficient of the 'x' variable
⇒ that is the slope
Ex. For the line y = x, the slope is 1
⇒A line with a positive slope rises from left to right while a line with a negative slope falls from left to right.
Ex. y=x has a positive slope and thus is rising
We want to find the equation that could represent the blue line
⇒ let's look into each equation and see whether they work or not
First case: [tex]y = -x[/tex]
⇒The equation given has the line falling, when the graph in the
equation is rising
⇒ not the answer
Second case: [tex]y=2x[/tex]
⇒ the equation given has the line that has a bigger slope than the
the equation shown, which has a smaller slope than y = x
⇒ not the answer
Third case: [tex]y=\frac{1}{2}x[/tex]
⇒ the equation given fits the requirement of having a rising slope that
is smaller than y = x
⇒ is a possible answer
Fourth case: [tex]y = 0.001x[/tex]
⇒ the equation given has a slope that is almost horizontal when the
line shown in the graph doesn't
⇒ not the answer
Thus after examing all the choices:
⇒ Answer: [tex]y=\frac{1}{2}x[/tex]

6. A right triangle includes one angle that
measures 30°, What is the measure of
the third angle?
A 30°
C 60°
B 90°
D 130°
Answer:
C, 60 degrees
Step-by-step explanation:
Right Triangle, with a 30 degree angle:
Given degrees:
90 (Right Triangle)
30
90+30 = 120
180-120 = 60
180 Degrees total in a triangle, you simply subtract the measure you have to fidn the third one.
Answer:
The measure of the third angle is 60°.
Step-by-step explanation:
We are given a right triangle that has a 90 degree and two other angles that are unknown.
Since one known angle is 90° and another angle given is 30° then the third angle must be 60°. All triangles must add up to 180°.
180° - 90° - 30° = 60°.
Here is an image of the demonstration/explaining types of triangles.
