5x-7=3x+21
2x=28
x=14
Answer:
14
Step-by-step explanation:
Subtracting 3x and adding 7 to both sides we get 2x = 28. Dividing the equation by 2 gets us x = 14.
A poll is given, showing 55% are in favor of a new building project. If 10 people are chosen at random, what is the probability that exactly 1 of them favor the new building project?
Answer:0.0041617435341797
Step-by-step explanation:
j
the probability that exactly 1 out of 10 randomly chosen people favor the new building project is approximately 0.2791, or 27.91%.
To calculate the probability that exactly 1 out of 10 randomly chosen people favor the new building project, we can use the binomial probability formula.
The formula for calculating the probability of getting exactly k successes in n trials, each with a probability of success p, is:
P(X = k) = C(n, k) * [tex]p^k * (1 - p)^{(n - k)[/tex]
In this case, n = 10 (number of trials), k = 1 (number of successes), and p = 0.55 (probability of success).
Using the binomial coefficient formula C(n, k) = n! / (k!(n - k)!), we can calculate the probability:
P(X = 1) = C(10, 1) * (0.55)¹ * (1 - 0.55)⁽¹⁰⁻¹⁾
P(X = 1) = 10 * (0.55)¹ * (0.45)⁹
P(X = 1) ≈ 0.2791
Therefore, the probability that exactly 1 out of 10 randomly chosen people favor the new building project is approximately 0.2791, or 27.91%.

On average,ea rectangular garden ha an area of 144 meter square. During a redesign of the garden center, the dimension of the rectangular garden are altered but the area is unchanged .The width is doubed and length is decreased by 12m.
Answer:
New dimensions are; Width = 12m and Length = 12m
Step-by-step explanation:
Let length of rectangle be L
Let width be W
Area of rectangle has a formula;
Area = Length x Width = LW
We are given the area = 144 m²
So,
LW = 144 - - - (eq1)
Now, we are told that width is doubled and length is decreased by 12m but area remains the same.
Thus, we have;
Width as 2W and Length as L - 12.
Area = 2W(L - 12)
So,
2W(L - 12) = 144 - - - (eq2)
Equating eq 1 and 2,we have;
LW = 2W(L - 12)
W will cancel out to give;
L = 2(L - 12)
L = 2L - 24
2L - L = 24
L = 24m
From equation 1, LW = 144
Thus; W = 144/L = 144/24
W = 6m
So new design of rectangle now has a dimension of;
Width = 2W = 2 × 6 = 12m
Length = L - 12 = 24 - 12 = 12m
So, new dimensions are; Width = 12m and Length = 12m

Hi can anyone help me with all three questions I have not been taught this topic
Answer:
240, 1800, 2040
Step-by-step explanation:
First find the surface area of the shape - base = 3 x 15 x 2 + 40 x 15 + 40 x 3 x 2 = 930 m ^2
Now find the area of base = 40 x 15 = 600
Now, the cost of painting = 10 pounds for 25 m^2. SO here cost = 600 / 25 x 10 = 24 x 10 = 240 pounds.
Now cost of tiles = 600 x 3 = 1800
Total cost = 1800 +240 = 2040

Find the equation of the line through point (1,−5) and perpendicular to y=18x+2. Use a forward slash (i.e. "/") for fractions (e.g. 1/2 for 12).
Answer:
y = -1/18x - 89/18
Step-by-step explanation:
Step 1: Find the slope of the perpendicular line
Do this by taking the negative reciprocal of the original line
m = -1/18
Step 2: Find b
y = -1/18x + b
-5 = -1/18(1) + b
-5 = -1/18 + b
b = -89/18
Step 3: Rewrite entire equation
y = -1/18x - 89/18

Answer:
B
Step-by-step explanation:
When you dilate by a factor of 0, this doesn't really make sense because the length of each side is multiplied by 0, and the shape basically doesn't exist anymore. When you multiply by a scale factor of 1, the figure does not change in size at all. When you dilate by a scale factor of 5, each side length gets 5 times larger, meaning that this is not a reduction. Hope this helps!

of the following sequences:
a) 4 1 -2-5-8
b) -7 -12 -17 -22 -27
Answer:
a: -3n+1
b:-5n-2
Step-by-step explanation:
a: it is -3+1 because you can see that the sequence is going down by 3, so it is the 3 times table, but because the number is 4, and 4 is 1 more than 3, you put plus one at the end. :)
b: similar to the last, it's going down by five, but it is two less this time, so you put minus two instead.

find the vertex of this function and decide if it is a maximum or a minimum point.
Answer: maximum point at (-3, 2)
Step-by-step explanation:
The vertex is either the highest or lowest point in the graph. You can see on that graph that the vertex is (-3, 2) because it the x-value -3 points from 0, and the y-value is 2 points from 0. You can also see that the vertex is the highest point on the graph because no points are above it, so it is the maximum value.

cereal is on sale for $3.60 for a 9-ounce box. what is the price per ounce?
Answer:
$0.40 per oz
Step-by-step explanation:
given that the cereal is $3.60 for a 9 oz box
i.e
9 oz ----> costs $3.60
1 oz ----> costs $3.60 ÷ 9 = $0.40
hence the unit rate is $0.40 per oz
Answer:
0.40 per ounce
Step-by-step explanation:
The question asks is to find the unit rate, or price per ounce.
To find this, we need to divide the price by the number of ounces.
price/ ounces
It costs $3.60 for 9 ounces of cereal.
$3.60/9 ounces
Divide $3.60 by 9 (3.60/9=0.4)
$0.4/ounce
It costs $0.40 per ounce of cereal.

Answer: (a) 7
Step-by-step explanation:
Range refers to the y-values.
(9, -1) --> y = -1
(8, 1) --> y = 1
(7, 2) --> y = 2
(6, 4) --> y = 4
(5, 8) --> y = 8
(4, 9) --> y = 9
Range: y = {-1, 1, 2, 4, 8, 9}
4, 8, and 9 are in the range. 7 is not.

Answer:
P = 40 cm
A = 51 cm^2
Step-by-step explanation:
Perimeter: Add the lengths of all sides. The sides whose length are not shown can be calculated by subtraction.
perimeter = 3 cm + 12 cm + 8 cm + 3 cm + (8 cm - 3 cm) + (12 cm - 3 cm) =
= 3 cm + 12 cm + 8 cm + 3 cm + 5 cm + 9 cm
= 40 cm
Area:
You can find the area by calculating the sides of smaller rectangles and adding the areas. You can also calculate the area by thinking of a large rectangle from which a smaller rectangle inside was removed. I'll use the second method.
area of larger rectangle = 12 cm * 8 cm = 96 cm^2
area of removed rectangle = (8 cm - 3 cm) * (12 cm - 3 cm) = 5 cm * 9 cm = 45 cm^2
shaded area = 96 cm^2 - 45 cm^2 = 51 cm^2
If AHLI – AJLK by the SSS similarity theorem, then
HL

JL KL
НІ
JK
JL
IK
KL
Answer:
HI/JK
Step-by-step explanation:
The ratio of similarity for the sides of the triangle is, KL/IL = HL/JL = HI/JK.
What are congruent triangles?In mathematics, the term "congruence" is used in a variety of contexts, each denoting a harmonic relationship, understanding, or correspondence.
As per the given data:
We are given two triangles ΔHLI and ΔJLK.
We are also given that both the traingles are similar to each other by the SSS similarity theorem.
Furthermore, we have to find out the similar ratios of the sides of the triangles.
As we are given ΔHLI ≈ ΔJLK.
According to the SSS postulate:
KL = IL ----- (1)
HL = JL ----- (2)
HI = JK ------ (3)
From equation (1), (2) and (3) we get:
KL/IL = HL/JL = HI/JK
Therefore, we have found the ratio of similarity for the sides of the triangle as, KL/IL = HL/JL = HI/JK
Hence, the ratio of similarity for the sides of the triangle is, KL/IL = HL/JL = HI/JK
