Step-by-step explanation:
[tex] \frac{2}{11} + ( \frac{4}{11} + \frac{1}{11} ) = ( \frac{2}{11} + \frac{4}{11} ) + \frac{1}{11} \\ \frac{2}{11} + \frac{5}{11} = \frac{6}{11} + \frac{1}{11} \\ \frac{7}{11} = \frac{7}{11} \\ [/tex]

Find the derivative of f(x) = 4x + 7 at x = 5.
Answer:
4 or x=3
Step-by-step explanation:
The power rule is
( d /d x ) x *n = n x *n − 1
I just used the power rule to solve
or
4x=5+7
Simplify 5+7 to 12
4x=12
Divide both sides by 4
x=12/4
Simplify 12/4 to 3
x=3

Carlos is building a screen door. He height of the door is 1 foot more than twice the width. What is the width of the door if the height is 7 feet?
Answer:
The answer is 3 feet.
Step-by-step explanation:
First, the height is 7 right. Then take away 1 foot since is said 1 foot more than twice the width. Then divide by 2 meaning twice. Meaning 7-1=6 6/2=3. There you go! Hope these formulas helped!
Answer:
3 feet
Step-by-step explanation:
To relate the height and width of the door, we can write an equation, which is derived from what is given in the problem. If we define w as the width and h as the height, the words, "1 foot more than twice the width" can translate to:
2w + 1, and this is equal to the height, so
2w + 1 = h
Now, we are given the height is 7. We substitute 7 where the height, h, is.
2w + 1 = 7
We can subtract 1 from both sides and divide by 2 to isolate x:
2w + 1 = 7
-1 -1
2w = 6
w = 3 - the width is 3 feet
Predict the number of deer in a 25 square mile section of the mountains based on the sampling from the figure
Help please it’s a test!

Find the sum of the arithmetic series given a1=8,a14=99,n=14.
Answer:
The sum of the series is: 749
Step-by-step explanation:
Given
[tex]a_1 = 8[/tex]
[tex]a_{14} = 99[/tex]
[tex]n = 14[/tex]
Required
The sum of the series
This is calculated using:
[tex]S_n = \frac{n}{2}[a_1 + a_n][/tex]
Substitute 14 for n
[tex]S_{14} = \frac{14}{2}[a_1 + a_{14}][/tex]
[tex]S_{14} = 7[a_1 + a_{14}][/tex]
Substitute values for a1 and a14
[tex]S_{14} = 7[8 + 99][/tex]
[tex]S_{14} = 7*107[/tex]
[tex]S_{14} = 749[/tex]

If 32% of a number is 64, what is the number?
A 50
B. 96
C. 100
D. 200
Answer:
20.48
Step-by-step explanation:
the answer is not in d option
Answer:
D. 200
Step-by-step explanation:
Let the number to be found be y.
Therefore, according to the question, we have the following linear equation:
32/100 × y = 64
Therefore, y = (64 × 100)/32 = 200
Hence, y is 200 and 32% of 200 is 64.
HELPPP! I need step by step!
Answer:
Step-by-step explanation:
P(A) = Probability of a student knowing how to play guitar
= no. of students who know how to play guitar / total no. of student
= 144/200
= 0.72
P(B) = Probability of a student is left-handed
= no. of students who is left-handed / total no. of student
= 141/200
= 0.705
P(A) and P(B) are calculated to be two real numbers and do not depend on each other. So event A and B are independent.
Answer:
Step-by-step explanation:
P(A) = 144/200 = 0.72
P(B) = 141/200 = 0.705 = 0.71
The two probabilities are similar but different. From the table, a large number of students who play guitar are also left-handed: 116. So the two probabilities are NOT independent - if u are left-handed, u are more likely to play guitar n vice versa.

here are the options
AB←→
is a chord.
AB←→
is a tangent line.
AB←→
is a diameter.
AB←→
is a secant line.
Answer:
AB←→
is a secant line.
Step-by-step explanation:
Not a chord because a chord ends and begins on a circular arch. (on the circle edge)
Cannot be a tangent line because a tangent line never touches the inside of a line.
Cannot be the diameter because a. it is always just inside the circle and I think it is the longest line (strait in the middle)
Can only be a secant line
In geometry, a secant of a curve is a line that intersects the curve at a minimum of two distinct points. The word secant comes from the Latin word secare, meaning to cut. In the case of a circle, a secant will intersect the circle at exactly two points.

9514 1404 393
Answer:
920 square feet
Step-by-step explanation:
The surface area is the sum of the areas of the different surfaces of the solid. This solid has 5 surfaces: 2 triangular bases and 3 rectangular faces.
The area of a triangle is given by the formula ...
A = 1/2·bh . . . . . where b is the base of the triangle, and h is its height
The dimensions shown on the "front" of the figure tell you the triangle has a base of 15 ft and a height of 8 ft. Its area is ...
A = (1/2)(15 ft)(8 ft) = 60 ft²
__
The rectangular faces all have a width of 20 ft. So, the sum of their rectangular areas will be that width multiplied by the sum of their lengths. We call this the "lateral area" of the prism.
lateral area = (base perimeter) × (prism width)
= (8 ft + 15 ft + 17 ft) × (20 ft) = 800 ft²
The sum of the areas of the two base triangles and the lateral area is the total surface area of the figure:
total area = 2×60 ft² + 800 ft²
total area = 920 ft²
Find the diameter of each circle.
7.8
They give you the radius, which is half the diameter.
3.9 * 2 = 7.8
answer:
1. 7.8 km
2. 17 ml
step-by-step explanation:
for the first one, we are given the radiusknow that, the diameter is two times bigger than the radiusso, for both of these we have to multiply what is given by 21 — 3.9 X 2 = 7.8 km
2 — 8.5 X 2 = 17 mi
