Answer:
97.5
Step-by-step explanation:
In my eyes I think we are talking about perimeter...
So then we would have to add up all the sides giving us the result.
30.25+30.25+18.5+18.5 = 97.5
And I am terribly sorry if it was incorrect I feel like i messed up on the "Disregard" part.. Anyways
Hope this helps! :)
Determine the missing angle measure.
Answer:
Step-by-step explanation:
Since you already know that one of the angles is 21 degrees, this helps you A LOT. In total the line is 180 degrees so to find x you just do 180-21 which equals 159
x+ 159 degrees
How do you write 5 more than a number?
x+5 is the way we can write 5 more than a number.
In a formula or equation involving mathematical operations, the representation of numbers by alphabet is referred to as algebra.
Using the knowledge provided above, we must translate the mathematical statement provided in the question into an algebraic expression. Let's say that number is "x". The result of adding 5 to the provided number is a number that is 5 greater than this number. Thus, a number that is 5 more than x is equal to x+5. As a result, "5 more than a number" is represented by the algebraic expression "x+5".

A rectangle frame needs to be constructed so that its width and length are in a ratio of 3:4 and its diagonal is 25 inches. What is the perimeter of the frame?
Answer:
70 inches
Step-by-step explanation:
From the diagram attached,
Assuming the width, lenght and diagonal of the rectangle forms a right angle triangle.
Applying pythagoras theorem,
a² = b²+c²................... Equation 1
Where a = diagonal = 25 inches, b = width = 3x inches, c = length = 4x inches
Substitute these values into equation 1 and solve for x
25² = (4x)²+(3x)²
625 = 14x²+9x²
625 = 25x²
25x² = 625
x² = 625/25
x² = 25
x = √25
x = 5 inches.
Therefore,
Width(w) = 3×5 = 15 inches
Length(l) = 4×5 = 20 inches
Perimeter (P) = 2(l+b)
P = 2(15+20)
P = 2(35)
P = 70 inches
Hence the perimeter of the frame is 70 inches
Jak starts to save at age 40 for a vacation home that he wants to buy for his 50th birthday. He will contribute $1000 each quarter to an account, which earns 2.1% interest, compounded annually. What is the future value of the investment, rounded to the nearest dollar, when jak is ready to purchase the vacation home?
Answer:
[tex]P=\$40840[/tex]
Step-by-step explanation:[tex]I=840[/tex]
From the question we are told that:
Time interval [tex]t=50-40=>10years[/tex]
Annual contribution [tex]X= 4*1000=>\$4000[/tex]
Annual interest rate [tex]r=2.1\%[/tex]
Generally the 10 years interest I is mathematically given by
[tex]I=X*t*r[/tex]
[tex]I=4000*0.021*10[/tex]
[tex]I=840[/tex]
Generally the equation for the future value of the investment [tex]P[/tex] is mathematically given by
[tex]P=X*t+840[/tex]
[tex]P=(4000*10)+840[/tex]
[tex]P=\$40840[/tex]

In a circle with radius 5.1, an angle intercepts an arc of length 30.3. Find the angle in
radians to the nearest 10th.
Answer:
5.9 radian
Step-by-step explanation:
Applying,
S = 2πrФ/360°................. Equation 1
Where s = length of the arc, r = radius, Ф = angle.
make Ф the subject of the equation
Ф = 360S/(2πr)........... Equation 2
From the question,
Given: S = 30.3, r = 5.1
Constant: π = 3.14
Substitute into equation 2
Ф = (360×30.3)/(2×5.1×3.14)
Ф = 340.58°
Ф = (340.58×2×3.14)/360
Ф = 5.9 radian

The integral 1 π(y2−y4) dy 0 represents the volume of a solid. Describe the solid.

O The solid obtained by rotating the region in the first quadrant bounded by the curves x = y2 and x = y4 around the y axis
O The solid obtained by rotating the region in the first quadrant bounded by the curves x = y and x = y2 around the x axis
O The solid obtained by rotating the region in the first quadrant bounded by the curves x = y and x = y2 around the y axis
The correct option is (d). The solid obtained by rotating the region in the first quadrant bounded by the curves x = y and x = y2 around the y axis
The difference between the areas beneath the two curves that form a boundary is the area between the curves. You will then have the area between the two curves, or the difference, between them.
In the cartesian coordinate system, a plane is divided into four areas by the X-axis, a horizontal line, and the Y-axis, a vertical line. The term "quadrant" refers to these four areas.Use washer method:The washer method enables us to use cylindrical discs with holes to compute the volume of solids in a rotation.
As we have mentioned, the washer method is an extension of the disk method. This technique is established so that we can also calculate for the volume of the solid returned by rotating the region bounded by two curves over the x and y axis.[tex]$$\begin{aligned}& V=\int_a^b \pi\left(x_1^2-x_2^2\right) d y \\& =\int_0^1 \pi\left(y^2-\left(y^2\right)^2\right) d y \\& =\int_0^1 \pi\left(y^2-y^4\right) d y\end{aligned}$$[/tex]

On a negatively skewed curve, which is true?
The statistical model is not good, and this is true for a negatively skewed curve.
What means negatively skewed curve?It is a statistical term implies that a curve is skewed at the left side.
In a statistical data for a certain distribution, we can get a negatively skewed curve when most of the data values are located on the right side of the distribution graph. The high concentration of values on the right side of distribution curve forms a long tail in the negative direction.
Which is true for negatively skewed curve?In general, negatively skewed curve is not good because it expresses the tendency of left tail events. Negatively skewed curves indicate a poor return from an investment. That means a person might be earn lower or no profit from his business. In case of an exam scores, negative skewed data value implies the question was too easy to perform better than usual.

The probability of picking a yellow sweet tart three times in a row is 0
What is probability?Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.
Given here, There are 4 pink, 1 blue, 2 yellow, 3 purple and 2 green SweetTarts. P(yellow ball three times in a row) = 2/12 ×1/11 ×0/10

Find the value of x.
x+16
9
Answer:
x = - 7
Step-by-step explanation:
given that the 3 angles in the triangle are congruent, then the triangle is equilateral with the 3 sides congruent , then
x + 16 = 9 ( subtract 16 from both sides )
x = - 7
Answer:
x=-7
Step-by-step explanation:
The triangles sides are all the same in length, therefore, you need all the sides to be equal to 9.
-12+16=4 This addition problem does not equal to 9 so it is not correct.
-7+16=9 This is correct because -7+16 or 16-7 = 9.
-9+16=7 This addition problem does not equal to 9 so it is not correct.
-11+16=5 This addition problem does not equal to 9 so it is not correct.
So, x = -7.
