Answer:
it would be an acute angle because it is less than 90
Answer:
It would be a right triangle
Step-by-step explanation:
A triangle must always have 3 angles that add up to 180°.
So if two angles are 45°, then the last angle has to add along with the 45° angles to equal 180°.
If you multiply 45 × 2 (since there are two angles that are 45°), you get 90, which is half of 180.
Also a 90° angle is a right angle, which would help you out with remembering.

Based on the graph, which inequality is correct for a number that is to the left of -4?
a
−7 > −4
b
−6 −4
d
−4 < −9
Answers
Answer:
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.
Step-by-step explanation:
Let us analyze all the given inequalities
Given the inequality
[tex]-7\:>-4[/tex]
As -7 can not be greater than -4, so [tex]-7\:>-4[/tex] is false.
Given the inequality
[tex]-8>-4[/tex]
As -8 can not be greater than -4, so [tex]-8>-4[/tex] is false.
Given the inequality
[tex]-4 < -9[/tex]
As -4 can not be lesser than -9, so [tex]-4 < -9[/tex] is false.
Given the inequality
[tex]-6 < -4[/tex]
As -4 is always greater than -6, so [tex]-6 < -4[/tex] will be true.
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.

50 points brainliest answer
Answers
Answer: x = 160
Step-by-step explanation:
540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x
540= 100-40+3x = 60+3x
480 = 3x
x = 160
Answer:
0.5x + 0.5x + (x-25) + (x-15) + 100 = 540
x + x - 25 + x - 15 + 100 = 540
3x + 60 = 540
3x = 540 - 60
3x = 480
x = 480/3
x = 160
If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.
Answers
Answer:
Step-by-step explanation:
1) Let the number be y
45%of y=63
45y/100=63
Y=6300/45
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Let the number be y
35%of y=49
35y/100=49
Y=4900/35
Y=140
So 80%of a number =80y/100
=80×140/100
=112.

The value of the function f (x) is 15/2 when x = -5 and is -73/2 when x = 3. What is the equation of the function?
Answers
Answer:
y = -5.5x - 20
Step-by-step explanation:
There are many functions that cross those points.
Assuming you're looking at a straight line.
y = mx + b
15/2 = -5m + b --> 7.5 = -5m + b
-73/2 = 3m + b --> -36.5 = 3m + b
Subtract the first from the second.
-44 = 8m
m = -5.5
Plugging back into the first equation, we get b = -20
Answer:
f(x) = −11/2x − 20

find the area of the regular hexagon PQRSTU of sides 8 cm as shown in the figure
Answers
Answer:
Area = 245m^2
Step-by-step explanation:
We can split this figure into 2 parts, a rectangle and a trapezoid.
Rectangle Sides = 10m and 20m
Area = 10m x 20m = 200m
Trapezoid formula = a+b/2(h)
a and b are the 2 bases and h is the height
Using a little deductive reasoning we get the following, 5+10/2(6)
This simplifies to 15/2(6) -->
7.5(6) = 45
Thus, our area is 200 + 45, or 245m^2

A flat-screen television was marked down by 35 percent, which reduced its price by $115.65. What was the original cost of the television before it was marked down?
$214.78
$330.43
$404.78
$4,047.75
Answers
Answer:
B
Step-by-step explanation:
35% of this price is :
35/100 × x = 0.35x
The price reduces by 0.35x.
This equals to 115.65
Now :
0.35x = 115.65

Trudy bought a $20 prepaid long distance phone card. for every minute that she talks, $0.25 is deducted from her card. The function f(m)=20-0.25m represents the amount of money f(m) she has left after talking m minutes.FInd the zero and explain what it means in the context of the situation.
Answers
Answer:
Step-by-step explanation:
Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0
f(m)=20-0.25m
0 =20-0.25m
-20 = -0.25m
m = -20/-0.25
m = 80
Hence Trudy will have talked for 80minutes if she has no money left

a 12 + 6n ≤ 30, so n ≤ 3
b 12 + 6n ≥ 30, so n ≤ 3
c 6n ≥30 + 12, so n ≥ 7
d 6n ≤30 + 12, so n ≤ 7

Answer:
The answer would be B.
Step-by-step explanation:
This is because the total cost is $30 so it can't be c or d. A shows that Annie can only have at least $30. this means that B is the only option left.

A parent is using a garden hose to fill up a small inflatable pool for her young child. The pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the hose in the pool for another 3 minutes before putting it away.
In this situation, the relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function.
In that function, which variable is independent? Which one is dependent?
Type your response in the space below.
Answers
Answer:
Independent variable = the time. Dependent variable = amount of water per minute
Step-by-step explanation;
The total amount of water depends on how long the hose is left on.
The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
Time is the independent variable.
The amount of water per minute is the dependent variable.

She turns the water off after 5 minutes but leaves the hose in the pool for another 3 minutes before putting it away.
What is the independent variable?Independent variables are the variables that the experimenter changes to test their dependent variable.
What is the dependent variable?A change in the independent variable directly causes a change in the dependent variable.
