Answer:
30%
Step-by-step explanation:
Key skills needed: Probability
1) There is a 70% chance of rain.
2) We need to find the chances against rain.
3) To do this, we need to use the fact that
70% + x = 100% (Since all the probabilities add up to 1 or 100%)
4) If you subtract 70% from both sides, x = 30%
5) This means the probability against rain is 30%.

For what value of x is JKLM a parallelogram?
A. 7
B. 14
C. 21
D. 28
The required value of x in the JKLM parallelogram is 21. Option C is correct.
Given that,
For a parallelogram, JKLM, the value of x is to be determined.
A parallelogram is a quadrilateral consisting of pairs of parallel sides.
Here,
For the parallelogram, the sum of the adjacent angle is 180°. So,
3x + 20 + 5x - 8 = 180
8x = 180 - 12
x = 168 / 8
x = 21
Thus, the required value of x in the JKLM parallelogram is 21. Option C is correct.

Answer:
y +2 = (1/4)(x +1)
Step-by-step explanation:
The given line is in slope-intercept form:
y = mx + b
where the slope (m) is -4 and the y-intercept (b) is +13.
For the perpendicular line, we need a slope that is the opposite reciprocal, or ...
-1/m = -1/(-4) = 1/4
A suitable form for the desired equation is the point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...
y +2 = (1/4)(x +1)

In the United States, the waterfall with the greatest single drop is Ribbon Falls in California which drops 1, 612 feet. Find its height in kilometers. 1 mi
Answer:
0.4913376 km
Step-by-step explanation:
To solve the given question above, we have our conversion factor
1 foot = 0.000305 kilometre
1,612 feet = x km
Cross Multiply
xkm = 1612 × 0.000305
xkm = 0.4913376 km
Therefore, the height in Kilometers is 0.4913376km

Step-by-step explanation:
A particle moves along a horizontal line. Its position function is s(t) for t is greater than or equal to 0. For each problem, find the velocity function v(t) and the acceleration function a(t).
1. s(t) = -t^4 + 12t^3
2. s(t) = -t^4 + 8t^3
Answer:
1) Velocity
[tex]v(t) = -4\cdot t^{3}+36\cdot t^{2}[/tex]
Acceleration
[tex]a(t) = -12\cdot t^{2}+72\cdot t[/tex]
2) Velocity
[tex]v(t) = -4\cdot t^{3}+24\cdot t^{2}[/tex]
Acceleration
[tex]a(t) = -12\cdot t^{2}+48\cdot t[/tex]
Step-by-step explanation:
From Physics we remember that velocity ([tex]v(t)[/tex]) and acceleration ([tex]a(t)[/tex]) are the first and second derivatives of the function position in time. That is:
1) Let [tex]s(t) = -t^{4}+12\cdot t^{3}[/tex], where [tex]t \ge 0[/tex]. The functions velocity and aceleration are, respectively:
Velocity
[tex]v(t) = -4\cdot t^{3}+36\cdot t^{2}[/tex]
Acceleration
[tex]a(t) = -12\cdot t^{2}+72\cdot t[/tex]
2) Let [tex]s(t) = -t^{4}+8\cdot t^{3}[/tex], where [tex]t\ge 0[/tex]. The functions velocity and acceleration are, respectively:
Velocity
[tex]v(t) = -4\cdot t^{3}+24\cdot t^{2}[/tex]
Acceleration
[tex]a(t) = -12\cdot t^{2}+48\cdot t[/tex]

In the provided sequence there are four terms after expanding the sequence and the sequence is 0 + 3 + 8 + 15.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
3
Σ n(n + 2)
n = 0
After expanding the above sequence:
= 0(0 + 2) + 1(1 + 2) + 2(2 + 2) + 3(3 + 2)
= 0 + 3 + 2(4) + 3(5)
= 0 + 3 + 8 + 15
As we can see in the above sequence there are four terms.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
Thus, in the provided sequence there are four terms after expanding the sequence and the sequence is 0 + 3 + 8 + 15.

Given:
Two numbers are 32 and 28.
To find:
The GCF of 32 and 28 and using the GCF find the factor of (32-28).
Solution:
(a)
Two numbers are 32 and 28. The factor form of given numbers are:
[tex]32=2\times 2\times 2\times 2\times 2[/tex]
[tex]28=2\times 2\times 7[/tex]
Clearly, 2 and 2 are common factors in both.
[tex]GCF(32,28)=2\times 2[/tex]
[tex]GCF(32,28)=4[/tex]
Therefore, the GCF of 32 and 28 is 4.
(b)
Using the GCF we need to find the factor of (32-28).
[tex]32-28=4\times 8-4\times 7[/tex]
Taking out the GCF, we get
[tex]32-28=4\times (8-7)[/tex]
Therefore, [tex]32-28=4\times (8-7)[/tex].

AAS - If two angles and a nonincluded side of one triangle are congruent to two angles and a nonincluded side of a second triangle, then the triangles are congruent.
HA - If the hypotenuse and an acute angle of a right triangle are congruent to the hypotenuse and an acute angle of another triangle, then the two triangles are congruent.

Alexander is a stockbroker. He earns 13% commission each week. Last week, he sold 6,400 worth of stocks. If he averages that same amount each week, how much did he make in commission in 2011?
Answer:
$43,264
Step-by-step explanation:
Given :
% Commission earned per week = 13%
Worth of stock sold last week = 6400
If same amount is averaged each week during 2011 ;
Number of weeks per year = 52
Worth of stock for the year = (6400 * 52) = $332,800
Average Commission for the year = 13% of 332,800
0.13 * 332,800
= $43,264

Michelle ordered 200 T-shirts to sell at the school carnival. She paid $2.80 per shirt, plus 5% of the total order for shipping. When she sells each T-shirt at the carnival, she adds a 150% markup to the total price she paid for the shirt (including the cost of shipping). What is the selling price of each T-shirt?
Answer: She should sell each T-Shirt for at least $4.41
Step-by-step explanation:
First you need to figure out what the total cost of the 200 t shirts was plus shipping. so 200 t shirts for 2.8 would cost $560 + a 5% shipping fee ($28) = 588 if she wants to markup by 150. you would then multiply 588 * 1.5 = $882. This would be the final money she wants to make by the end of her school carnival. Divide 882/200 (amnt of t-shirts) to get $4.41 per shirt
The diagram shows a triangle.
13.4 cm
7.6 cm
Work out the area of the triangle.
Answer:
Area of the triangle = 12.92 cm²
Step-by-step explanation:
Area of a triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
From the figure attached,
Length of base of the triangle = 7.6 cm
Length of the height of the triangle = 3.4 cm
Area of the triangle = [tex]\frac{1}{2}(7.6)(3.4)[/tex]
= 12.92 square cm

Similar triangles may or may not be congruent
The true statement is (b) BC EF
From the question, we have the following highlights about the triangles
The angles at points C and F are congruent (45 degrees)The angles at points B and E are congruent (50 degrees)The above represents the AA theorem
For the triangles to be similar by ASA, then the side lengths between the equal angles must be similar
The side lengths are BC and EF
Hence, the true statement is (b) BC EF
