Question:
Matthew walks 4/10 to mile to Zack's house. Which fraction is equivalent to 4/10?
Answer:
[tex]Fraction = \frac{2}{5}[/tex]
Step-by-step explanation:
Given
[tex]Fraction = \frac{4}{10}[/tex]
Required
Determine its equivalent
To do this, we simplify the fraction
Divide by 2/2
[tex]Fraction = \frac{4/2}{10/2}[/tex]
[tex]Fraction = \frac{2}{5}[/tex]
Hence, 2/5 is an equivalent fraction

Find the missing height of the solid figure
9514 1404 393
Answer:
5 in
Step-by-step explanation:
The figure's angles are presumed to be right angles everywhere, so the left-side vertical dimension is equal to the right-side vertical dimension.
The right side is marked as 15 inches.
The left side has two vertical segments, one of which is 10 inches. Since the total left-side height must be the same as the right-side height, we have ...
10 in + ? = 15 in
? = 5 in . . . . . . subtract 10 in
The missing height is 5 inches.
If a triangle is rotated about the y-axis as shown below, what three-dimensional polyhedral would be formed?
An image of a right triangle centered at the origin is shown with an arrow showing motion about the y axis.
(1 point)
Triangular prism
Cone
Cylinder
Square pyramid
Answer:
Cone
Step-by-step explanation:
I took the test and got it right :)
The triangle is rotated about the y-axis then a cone will be formed.
It is given that the triangle is rotated about the y-axis as shown in the picture.
It is required to find what three-dimensional polyhedral would be formed.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have an image of a right triangle centered at the origin in the picture, if we rotate it about the y-axis we will get a cone because the side which is at the y-axis will be fixed and the base of the triangle will move about the y-axis which will make a circular shape similarly the other side(hypotenuse) will also rotate about the y-axis which will create an outer surface for the cone.
Thus, the triangle is rotated about the y-axis then a cone will be formed.

If a fair die is rolled twice and two numbers X1=result of the first roll and X2=result of the second roll are obtained. Given that X1+X2=7, what is the probability that X1 =4 or X2 =4
Answer:
P = 2/3 = 0.67
Step-by-step explanation:
Assuming that X1 + X2 = 7
The total number of outcomes such that X1 + X2 = 7 are:
X1 = 3, X2 = 4
X1 = 4, X2 = 3
X1 = 1, X2 = 6
X1 = 6, X2 = 1
X1 = 2, X2 = 5
X1 = 5, X2 = 2
So there are 6 total outcomes such that X1 + X2 = 7
Now, the probability that X1 = 4 is equal to the quotient between the number of outcomes where X1 = 4 (only one outcome) and the total number of outcomes (6)
Then:
p = 1/6
And the probability that X2 = 4 is calculated in the same way, then the probability is:
q = 1/6
Now, the probability that X1 = 4 or X2 = 4 is the sum of both probabilities we've found above, then:
P = p + q = 1/6 + 1/6 = 2/6 = 2/3 = 0.67

Find X and arc KGH
Answer:
x = 21°
arc KGH = 228°
Step-by-step explanation:
The sum of the arcs = 360°
9x - 22° + 61° + 5x - 7° + 34° = 360°
combine like terms:
14x + 66° = 360°
subtract 66° from both sides of the equation:
14 x = 294°
x = 21°
arc KGH = 9(21°) - 22° + 61° = 228°
Nine scores have an average of 8. Scores x and x+1 are added, and these increase the average to 9. Find x
Answer:
x must be 13
Step-by-step explanation:
Represent the nine scores by a, b, c, d, e, f, g, h, i.
Write the following equation to indicate that the average of these nine scores is 8:
a+b+c+d+e+f+g+h+i
----------------------------- = 8, or a+b+c+d+e+f+g+h+i = 72 if we multiply both
9 sides of this equation by 9.
Next, we add scores x and x+ 1 to
a+b+c+d+e+f+g+h+i + x + x + 1
and divide the result by 11, as there are now 11 scores instead of just 9:
a+b+c+d+e+f+g+h+i + x + x + 1
----------------------------------------------
11
Earlier, we saw that a+b+c+d+e+f+g+h+i = 72. We can now replace
a+b+c+d+e+f+g+h+i in the above fraction by 72:
72 + 2x + 1
------------------- = 9 (as the new average is 9)
11
Multiplying both sides of this equation by 11 results in:
73 + 2x = 99, or 2x = 26.
Then x must be 13, and x + 1 must be 14.
What is the value of x?
(9x - 3)
(6x)
48°
Enter your answer in the box.
X=
Answer: x = 9
Step-by-step explanation:
The sum of three interior angles of a triangle is 180°.
(9x - 3) + (6x) + 48° = 180°
9x - 3 + 6x + 48 = 180
15x + 45 = 180
15x = 135
x = 9

Solve for y in the following equations: -4x -8y = -8 when x = -4
A) 5
B) 3
C)-5
D) 8
given the following sequences : -17 -25 -33 -41... write an explicit formula and find the 28th term in this sequence
Answer:
a(n) = -8n -9
a(28) = -233
Step-by-step explanation:
a(n) = a(1) + (n - 1)d
n is the nth term, a(1) is the first term, d is the common difference.
*d = -25 - (-17) = -8
a(n) = -17 + (n - 1)(-8)
= -17 + (-8n + 8)
= -17 - 8n + 8
= -8n - 9
For the 28th term
a(28) = -8(28) - 9
= -224 - 9
= -233

In parallelogram IFGH, mF = (x + 20° and mi
(4x – 10)
Find the value of x.
Answer:
x = 34
Step-by-step explanation:
4x - 10 + x + 20 = 180
5x + 10 = 180
5x = 170
x = 34
Answer:To find the value of x, we can use the property of opposite angles in a parallelogram. In a parallelogram, opposite angles are congruent.
Given that mF = x + 20° and mi = 4x - 10, we can set these two expressions equal to each other:
x + 20° = 4x - 10
Now, let's solve for x:
x - 4x = -10 - 20°
-3x = -30°
Divide both sides by -3:
x = -30° / -3
x = 10°
Therefore, the value of x is 10°.
Step-by-step explanation:
Find a degree 3 polynomial with real coefficients having zeros 5 and 4i and a lead coefficient of 1. Write P in expanded form
Given:
The degree of the polynomial = 3
Leading coefficient = 1
Zeros of the polynomial are 5 and 4i.
To find:
The expanded form of the polynomial.
Solution:
According to the complex conjugate root theorem, if a+ib is a zero of a polynomial, then a-ib is also a zero of that polynomial.
Here, zeros of the polynomial are 5 and 4i. It means the third zero of the polynomial is -4i. So, the factors of the polynomial are [tex](x-5),(x-4i),(x+4i)[/tex].
The required polynomial is the product of its all factor and a constant which is equal to the leading coefficient. Here, the constant is 1. So, the required polynomial is
[tex]P(x)=1(x-5)(x-4i)(x+4i)[/tex]
[tex]P(x)=(x-5)(x^2-(4i)^2)[/tex]
[tex]P(x)=(x-5)(x^2+16)[/tex] [tex][\because i^2=-1][/tex]
[tex]P(x)=(x-5)(x^2+16)[/tex]
On further simplification, we get
[tex]P(x)=x^3+16x-5x^2-80[/tex]
[tex]P(x)=x^3-5x^2+16x-80[/tex]
Therefore, the required polynomial P is [tex]P(x)=x^3-5x^2+16x-80[/tex].

<K=90°[inscribed is triangle on a semicircle is 90°]
now in triangle JKL
<J+<K+<L=180°[ sum of interior angles of a triangle is 180°]
49°+90°+<L=180°
<L=180°-49°-90°=41°
:.arcJK=41°
is your answer.
Answer:
Question:Find the measure of the arc or angle indicated.
Solution:In ∆LRK & ∆JKL,
∠KRL= ∠LJK = 49°
( inscribed angle standing on a same Aaka equal in a circle)Now , In ∆JKL,
∠JKL = 90°
(angle suspended to the center of the circle =90°)Now,
construction: A line segment OK joining the points O(center)& KSince, OK&OJ are the radii of the same circle,
Hence, OK = OJ
.°. ∠JKO = ∠OJK = 49°
Now,
In ∆ JOK,
∠JKO +∠OJK+ ∠JOK = 180°
Angle sum property of a∆∠JOK = 180°- (∠JKO +∠OJK)
∠JOK = 180°-(49°+49°)
∠JOK = 180°- 98°
∠JOK = 82°
Hence, 82° is your answer[tex] \\ \\ [/tex]
