Answer:
x = 99°
Step-by-step explanation:
Given that,
The first angle = 40°
The second angle = 41°
We need to find the value of x. We know that the sum of angles of a triangle is equal to 180°. So, using this property.
40+41+x = 180
81+x=180
x = 180-81
x = 99°
So, the value of x is equal to 99°.

(5) + 2 = 7
2(5) + 3 = 13
13 * 7 = 91
Step-by-step explanation:
Given area = 91m²
length = 2x+3 m
breadth = x +2 m
we know,
Area = length x breadth
91 = (2x+3) x (x+2)
91 = 2x² + 4x + 3x + 6
91 = 2x² + 7x + 6
2x² + 7x - 85 = 0
(2x+17)(x−5)=0
2x+17=0 or x−5=0

A polyhedron (not regular) has 10 vertices and 5 faces. How many edges does it have?
Answers
Answer:
13 edges
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2 ( F is faces, V is vertices and E is edges ) , then
5 + 10 - E = 2
15 - E = 2 ( subtract 2 from both sides )
13 - E = 0 ( add E to both sides )
13 = E
The polyhedron has 13 edges

The graph of an exponential function passes through the points (1,1/16) and (3,1/64) . Write an equation for the function in the form y=a*b^x
Answers
Answer:
y=3,1*64^1,1/16
Step-by-step explanation:
The exponential equation will be written as, [tex]y=(\dfrac{1}{8})(\dfrac{1}{2})^x[/tex].
What is an exponential expression?Powers can simply be expressed in concise form using exponential expressions. The exponent shows how many times the base has been multiplied. Since 2 is the "base" and 5 is the "exponent,"
It can be represented as 2x2x2x2=25 for the number 32. This phrase should be understood as "two to the fifth power."
Given that the graph of an exponential function passes through the points (1,1/16) and (3,1/64).
The values of a and b will be calculated as,
1/16 = ab
1/64 = ab³
1/64 = ab x b²
1/64 = 1 / 16 x b²
b = 1 / 2
a = 1 / 8
The exponential equation will be written as,
[tex]y=(\dfrac{1}{8})(\dfrac{1}{2})^x[/tex].
Therefore, the exponential equation will be written as, [tex]y=(\dfrac{1}{8})(\dfrac{1}{2})^x[/tex].

The average grade for an exam is 74, and the standard deviation is 7. The grades are curved to follow a normal distribution.
What is the probability that the grade of a randomly selected students score is more than 60?
Answers
Answer:
0.9772 = 97.72% probability that the grade of a randomly selected students score is more than 60.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The average grade for an exam is 74, and the standard deviation is 7.
This means that [tex]\mu = 74, \sigma = 7[/tex]
What is the probability that the grade of a randomly selected students score is more than 60?
This is 1 subtracted by the pvalue of Z when X = 60. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 74}{7}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a pvalue of 0.0228
1 - 0.0228 = 0.9772
0.9772 = 97.72% probability that the grade of a randomly selected students score is more than 60.

so using this formula gives us 1275.62897 but rounded off gives us 1,275.63 ft3
ok the diameter is 21 3/4ft i converted it to a decimal, 21.75ft so to get the radius i 21.75ft/2= 10.875ft
ok to continue
V=1/3(hπr²)

V=1/3(118.265625ft)

Answer:
12 ft
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 41.5°
Opposite = 8 ft
Length of handrail =?
We can obtain the length of the handrail by calculating the Hypothenus. This can be obtained as follow:
Angle θ = 41.5°
Opposite = 8 ft
Hypothenus =?
Sine θ = Opposite /Hypothenus
Sine 41.5 = 8 / Hypothenus
0.6626 = 8 / Hypothenus
Cross multiply
0.6626 × Hypothenus = 8
Divide both side by 0.6626
Hypothenus = 8 / 0.6626
Hypothenus = 12 ft
Thus, the Lenght of the handrail is 12 ft

A.
The amount of money he had to spend on the backpack.
B.
The amount of tax for the backpack.
C.
The price of the backpack, including tax.
D.
The price of the backpack, not including tax.
Answers
Answer:
Option A
Step-by-step explanation:
Y is the amount of back pack
The total amount is represented by m
If Y is the cost of back pack purchased by Oliver, then 0.7 Y is the tax applicable on the purchase of back pack
Hence, the remaining cost would be total amount with Oliver minus the cost of back pack and the tax applicable on the purchase of back pack
Remaining cost = m - (y + 0.07y)
Hence, option A is correct

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a batter hits a baseball with an initial horizontal speed of 74 mph and an initial rate of climb of 61 mph.
[A] -
The initial speed of the ball when it leaves the bat will be -
v = √(v(h)² + v(c)²)
v = √((74)² + (61)²)
v = 95.9 mph
[B] -
The angle made will be -
Ф = tan⁻¹(61/74) = 39.49°
Therefore -
The initial speed of the ball when it leaves the bat will be 95.9 mph.The angle made by the ball with horizontal is 39.49°.To solve more questions on 2 -D figures, visit the link below-

Answers
The most common measures are mean, median, and mode. MIS. Measure ... For an even amount of data values - Calculate the mean of the two middle numbers. ... store had total sales of $436, $650, $530, $500,$650, $489, and $423 last week. ... would make the store's sales last week appear the most profitable? Explain.
The mean and the median of the data will be $525.43 and $500, respectively.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
A retail store had total sales of $436, $650, $530, $500, $650, $489, and $423 last week.
Then the mean of the data will be
Mean = (436 + 650 + 530 + 500 + 650 + 489 + 423) / 7
Mean = $525.43
Arrange the data in ascending order, then we have
$423, $436, $489, $500, $530, $650, $650
Then the median of the data will be
Median = $500
