Answer:
90
Step-by-step explanation:
Find total marks needed for a 90.
90 x 4 = 360 marks
Then, add up the marks on the three tests.
83+91+86 = 260 marks
Finally, subtract from the 360 marks needed.
360 - 260 = 100
Thus, the student needs to score 100 marks in order to get a 90.
What is the range of the function f(x) = 4x + 3 when the domain is {−3 , 2 , 4}
Hey there! I'm happy to help!
The range of a function is all of the outputs. Let's plug in our inputs and find these outputs.
4(-3)+3
-12+3
-9
4(2)+3
8+3
11
4(4)+3
12+3
15
We order these from least to greatest, giving us a range of {-9,11,15}.

So since there is 3 days and the total is 24 you divide and that will give you 8! Integers are a whole number btw (:
A large ice chest holds 62 liters of water. A smaller chest holds 4/5 as much water
How many liters of water does the smaller chest hoid? Move a number to each box to show the answer. HELP ASAP.
Answer:
Step-by-step explanation:
Since a large ice chest holds the water = 62 liters
And smaller chest holds the water = [tex]\frac{4}{5}[/tex] of the larger ice chest
= [tex]\frac{4}{5}\times 62[/tex]
= [tex]\frac{248}{5}[/tex] liters
Therefore, fraction that represents the amount of ice water in the smaller ice chest will have 0 in the first box, 248 in the numerator and 5 in the denominator.
[tex]0\frac{248}{5}[/tex]

3.a.Sketch a line through the point
(-2,5) such that as an x-value
increases by 3. the y-value
decreases by 2.
y
o
Answer:
Step-by-step explanation:
Let the equation of the line passing through a point (x', y') and slope 'm' is,
y - y' = m(x - x')
Since x-value increases by 3,
Δx = 3
And y-value decreases by 2,
Δy = -2
Therefore, slope = [tex]\frac{\triangle y}{\triangle x}[/tex]
Slope = [tex]-\frac{2}{3}[/tex]
Equation of the line passing through (-2, 5) and slope = [tex]-\frac{2}{3}[/tex] will be,
y - 5 = [tex]-\frac{2}{3}(x+2)[/tex]
y = [tex]-\frac{2}{3}x-\frac{4}{3}+5[/tex]
y = [tex]-\frac{2}{3}x+\frac{11}{3}[/tex]
y = [tex]\frac{1}{3}(-2x+11)[/tex]
Table for input-output values will be,
x -2 0 1 2 3
y 5 3.7 3 2.3 1.7
We can plot these points to get the line on a graph.

• D. 9/10
Answer:
The answer is D. 9/10
Step-by-step explanation:
The reason why is because the numerator 3 multiplied by 3 gives you 9 and the denominator doesn't change, so the answer is 9/10.

Answer:
B . [tex]d = \sqrt{x^2+y^2}[/tex]
Step-by-step explanation:
The original formula is
[tex]d = \sqrt{(x_2-x_1)^2 +(y_2-y_1)^2} \\\\x_2-x_1 =x\\y_2-y_1 =y\\\\So... \: ;\\d = \sqrt{x^2+y^2}[/tex]

Answer:
7x for the first expression
2x + 2y + 8x^2
Step-by-step explanation:
5(2x) - 3x
= 10x - 3x = 7x
2x + 2y + x^2(8)
= 2x + 2y + 8x^2

Answer:
Step-by-step explanation:
[tex]2 \times 10^{-3}=\frac{2}{10^3}=\frac{2}{1000}=0.002\\3 \times 10^{-2}=\frac{3}{10^2}=\frac{3}{100}=0.03=0.030\\0.030>0.002\\so~3 \times 10^{-2} ~is~larger~than~the~other.[/tex]

Find the midpoint of the line segment with the given endpoints. (-3.1, -2.8) and (-4.92, -3.3)
Answer:
Step-by-step explanation:
(-3.1 - 4.92)/2 = -8.02/2 = -4.01
(-2.8 - 3.3)/2 = -6.1/2= -3.05
(-4.01. -3.05) the midpoint
Which set of angle measures could be the interior angles of a triangle? A. 15°, 48°, 27° B. 56°, 45°, 46° C. 42°, 84°, 64° D. 93°, 29°, 58°
Answer:
D. 93°, 29°, 58°
Step-by-step explanation:
In a triangle we can only have 3 Interior angles.
The sum of the Interior angles in a triangle = 180°
Adding up the given Interior angles in the above question:
A. 15°, 48°, 27°
= 15° + 48° + 27°
= 90°
90° ≠ 180°
Option A is wrong
B. 56°, 45°, 46°
= 56 ° + 45° + 46°
= 147°
147° ≠ 180°
Option B is wrong
C. 42°, 84°, 64°
= 42° + 84° + 64°
= 190°
= 190° ≠ 180°
Option C is wrong.
D. 93°, 29°, 58°
93° + 29° + 58°
= 180°
180° = 180°
Option D is the correct Option.
Therefore, the set of angle measures that could be the interior angles of a triangle is Option D. 93°, 29°, 58°

For which values of a the system has at least one solution: x≤7 x≥a urgent pls help now
Answer:
We have the system:
x ≤ 7
x ≥ a
Now we want to find the possible values of a such that the system has, at least, one solution.
First, we should look at the value of a where the system has only one solution:
We can write the 2 sets as:
a ≤ x
x ≥ 7
So, writing both together:
a ≤ x ≤ 7
if a is larger than 7, we do not have solutions.
then a = 7 gives:
7 ≤ x ≤ 7
Here the only solution is 7.
Now, if a is smaller than 7, for example 5, we have:
5 ≤ x ≤ 7
Now x can take different values, so we have a lot of solutions.
Then the restrictions for a, such that the system has at least one solution, is:
a ≤ 7.
