A student has taken three math tests so far this semester. His scores for the first three tests were 71, 75, and 79. Part A: Suppose his test scores continue to improve at the same rate. What will be the grade on the sixth and (final) test?
Answer:
The grade of this sixth and (final) test would be 91.
Step-by-step explanation:
This is an arithmetic series since each time the data is increasing by the common difference of 4, and we already know a₁ which is the first term in the sequence is 71, therefore we can say:
a₁ = 71
r = 4
a₆ = the sixth term that needs to be found out
n = 6
Formula of an arithemetic series:
aₙ = a₁ + r(n - 1)
a₆ = 71 + 4(6 - 1)
a₆ = 71 + 4(5)
a₆ = 71 + 20
a₆ = 91
Hence, the grade of this sixth and (final) test would be 91.
Hope this helps!

Find the distance d. Round your answer to the nearest tenth. Show all your work. Thanksss!
Answer: the distance for d is about 5.8 units
Step-by-step explanation:
Use the pythagorean theorem. a^2 + b^2+= c^2 . in this case, c^2 is the distance for d.
5^2 + 3^2= d^2
25+9= d^2
34= d^2
square both sides and d is approximately 5.818

Answer:
The circumference of the circle is 75.36cm
Step-by-step explanation:
There are two ways you can solve this, one is by using the radius and multiplying it by 2 and then pi which is 3.14, and the other is to use the diameter which is the radius times 2, and the thingy gave you the diameter, and you multiply it by 3.14 which is pi
If the measurement of angle 2 is 120 degrees, what is the measurement of angle 7?
Answer:
The measure of angle 7 is twice the measure of angle 2, then the measure of angle 7 is
angles 2 and 7 equal 180 degrees. 180 = 2x + x
180 = 3x
x = 60
angle 7 is twice x
angle 7 = 120
Step-by-step explanation:
5x−4y=−10
y=2x−5
x=x=x, equals
y=y=y, equals
Answer:
✎ ANSWER:-[tex]y = 2x - 5[/tex]
Substitute the value of y as 2x - 5 in the equation.
[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]
Now, find the value of y
[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]
⎇ x = x = x, equals 10
⎇ y = y = y, equals 15
Answer:
if y = 2x-5
then in the second equation we can find the value of x
5x-4(2x-5) = -10
5x-8x+20 = -10
-3x = -30
x = 10
then the value of y = 20-5 = 15
therefore the value of x = 10 and y =15 (ans)

Ann and ben had some apples. The ratio of the number of Ann's apples to the ratio of Ben's apple is 2:3. Ann gave 6 apples to ben and now the ratio becomes 1:3. How many apples are all together?
Answer:
There are 12 apples in total.
Step-by-step explanation:
If Anne gave Ben 6 apples then heres how:
2:3 subrtact 6 apples = 1:3
6 apples x 2 = 12 apples =
2 ÷ 2 = 1
Hence, your answer is double 6 which is 12 apples.

When a graph is symmetric about the origin, it is an function.
When a graph is symmetric about the y-axis, it is an function.
A function is considered if f(-x) =
f(x), and it is considered
=
if f(-x) = -f(x).
Answer:
odd; even; even; odd
Step-by-step explanation:
The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know when the graph is symmetric about the origin it is an off function.
When the graph is symmetric about the y axis it is an even function.
When f(-x) = f(x) it is an even function
When f(-x) = -f(x) it is an odd function.
Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

Determine the approximate value of ø
a)41.89
b) 48.20
c)33.70
d)56.30
Answer:
B,48.2
Step-by-step explanation:
To solve this we need to use SOH, CAH, TOA
we have the adjacent and hypotonouse so it's easiest to use CAH
let theta (angle) = x
cos(x)=4/6
to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)
x=48.1896851
which rounds to 48.2
please help me complete these -5a^2+ 5a = _______(a – 1) and 18x^2 + 2x³ = _______(9 + x) I need to complete the blanks
Answer:
Step-by-step explanation:
-5a^2+ 5a factors as follows: -5(a - 1) (so -5 goes into the blank space).
18x^2 + 2x³ factors as follows: 2x^2(x + 9) (so 2x^2 goes into the blank space)
5. A ladder leans against a building. The top of the ladder touches the building 10 feet above the ground. The foot of the
ladder is 4 feet from the building. Find, to the nearest degree, the angle that the ladder makes with the level ground.
(3 points)
Answer:
68 degrees
Step-by-step explanation:
The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.
The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft. Thus,
tan x = (opp side) / (adj side) = 10/4. Using the inverse tangent function, we find that the angle in question is
arctan (10/4) = 68 degrees

THIS IS AREA OF CIRCLES PLS ANSWER
Answer:
75ft^2
Step-by-step explanation:
A = pi*r^2
The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.
Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.
3*(5)^2 = A
Simplify
3*25

Find the value of x and y
Answer:
2x + 20 = 3x-10
2x -3x = -20-10
-x = -30
x= 30
Checking part:
2x+20 = 2(30) +20 = 60+20 = 80
3x-10 = 3(30) - 10 = 90-10 = 80
Hence, the final answer is x = 30.
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
the angle should be the same so,
2x+20=3x-10
x=30
