Answer:
x≥9
Step-by-step explanation:
First you need to take 3 from both sides.
5x + 3 -3 ≥ 48 -3 which is 5x ≥ 45
Then you need to divide both sides by 5.
5x÷5 ≥ 45÷5 with gives the answer x ≥ 9
The solution to the given inequality (5x+3 ≥48) is x ≥ 9
To solve an equation or an inequality, we will determine the value of the variable in the equation or inequality.
From the question,
To solve the given inequality 5x+3 ≥48
We will determine the value of the variable x, that satisfies the inequality.
Now, to do this
First, subtract 3 from both sides, that is
[tex]5x+3-3 \geq 48-3[/tex]
We get
[tex]5x \geq 45[/tex]
Now, divide both sides by 5
[tex]\frac{5x}{5} \geq \frac{45}{5}[/tex]
[tex]x\geq 9[/tex]
Hence, the solution to the given inequality is x ≥ 9

To factor the quadratic
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (+ 1)
The factors are + 4 and - 3, since
4 × - 3 = - 12 and 4 - 3 = + 1, thus

Find the probability of a student being 34 years old or younger. Express your answer as a percent
Answer:
79%
Step-by-step explanation:
The probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32 is 0.7881 = 78.81%
When the distribution is normal, we use the z-score formula.
What is 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.
In this question:
[tex]\mu=28,\sigma=5[/tex]
Find the probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32.
This is the p-value of Z when X = 32. So
[tex]Z=\frac{X-\mu}{\sigma}[/tex]
[tex]Z=\frac{32-28}{5}[/tex]
[tex]Z=0.8[/tex]
Z=0.8 has a p-value of 0.7881
0.7881 = 78.81% probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32.

Do you rectangular floor of a classroom is 36 feet length and 32 feet in width. They scale drawing of the Florida has a length of 9 inches. What is the area square inches of the floor in the scale drawing
Answer:
72 sq. inch.
Step-by-step explanation:
9 inches in feet is 9/12 = 0.75 feet.
We can set up a ratio to figure out the width of the scale drawing.
[tex]\frac{36}{0.75}=\frac{32}{x}[/tex]
This means "if 36 feet is 0.75 feet in drawing, how much (let that be x) is 32 feet?"
let's cross multiply and solve for x:
[tex]\frac{36}{0.75}=\frac{32}{x}\\36x=32*0.75\\36x=24\\x=\frac{24}{36}=\frac{2}{3}[/tex]
So width is 2/3 feet and length is 0.75 feet.
Converting back to inches (since we need the area in sq. inches):
2/3 feet = 2/3 * 12 = 8 inches, and
0.75 feet = 0.75 * 12 = 9 inches
Hence, area is 8 * 9 = 72 sq. inches.

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of
3 large boxes and
5 small boxes has a total weight of
116 kilograms. A delivery of
9 large boxes and
7 small boxes has a total weight of
238 kilograms. How much does each type of box weigh?
Answer:
Small box weighs 13.75 kg & large box weighs 15.75 kg
Step-by-step explanation:
We can write 2 simultaneous equation and solve for weight of each box.
Let weight of large box be l and small box be s.
"3 large boxes and 5 small boxes has a total weight of 116 kilograms":
[tex]3l+5s=116[/tex]
and
"9 large boxes and 7 small boxes has a total weight of 238 kilograms":
[tex]9l+7s=238[/tex]
Now we can solve for l in the 1st equation and put it into 2nd equation and get s:
[tex]3l+5s=116\\3l=116-5s\\l=\frac{116-5s}{3}[/tex]
now,
[tex]9l+7s=238\\9(\frac{116-5s}{3})+7s=238\\3(116-5s)+7s=238\\348-15s+7s=238\\348-238=15s-7s\\110=8s\\s=\frac{110}{8}=13.75[/tex]
now we plug in 13.75 into s into equation of l to find s:
[tex]l=\frac{116-5s}{3}\\l=\frac{116-5(13.75)}{3}\\l=15.75[/tex]

Step-by-step explanation:
By SOH CAH TOA, the sine of an angle is its opposite side divided by the hypotenuse.
The opposite of ∠C is 5, and the hypotenuse is 13.
So, sin(C) = 5/13 ≈ 0.38.
For this case we have to define trigonometric relations of rectangular triangles that the sine of an angle is given by the leg opposite the angle on the hypotenuse of the triangle. That is to say:
[tex]Sin (C) = \frac {5} {13}\\Sin (C) = 0.38[/tex]

Answer:
10y + 2
Step-by-step explanation:
The formula for the perimeter of a rectangle or square is [length + length + width + width = perimeter or 2(length) + 2(width) = perimeter]
Our length here is y + 2. Either formula you use, [(y+2) + (y+2) or 2(y+2)] you should get the answer 2y + 4.
Next our width. The width is 4y-1. Either formula you use, [(4y-1) + (4y-1) or 2(4y-1)] you should get 8y - 2.
Then, simply add (2y+4) and (8y-2) to get 10y + 2. So, the perimeter of the garden is 10y + 2.

How to determine the transformation (mapping) rule?In Mathematics, a translation is a type of transformation that shifts every point of a geometric object in the same direction on the cartesian coordinate, and for the same distance.
Based on the information provided in the diagram, we have the following:
(x, y) → (x + h, y + k)
(0, 0) → (-2, 0).
-2 = x + h
-2 = 0 + h
h = 0 - 2
h = -2 (2 units left)
0 = y + k
0 = 0 + k
k = 0.
In conclusion, a horizontal translation of 2 units to the left would map the parent cubic function f(x) to the transformed cubic function g(x);
g(x) = f(x + 2)

Transform each polar equation to an equation in rectangular coordinates and identify its shape.
(a) r=6
(b) r= 2 cos theta
please show ur work
Answer:
(a) [tex]x ^ 2 + y ^ 2 = 6 ^ 2[/tex]
(b) [tex](x-1) ^ 2 + y ^ 2 = 1[/tex]
Step-by-step explanation:
Remember that to convert from polar to rectangular coordinates you must use the relationship:
[tex]x = rcos(\theta)[/tex]
[tex]y = rsin(\theta)[/tex]
[tex]x ^ 2 + y ^ 2 = r ^ 2[/tex]
In this case we have the following equations in polar coordinates.
(a) [tex]r = 6[/tex].
Note that in this equation the radius is constant, it does not depend on [tex]\theta[/tex].
As [tex]r ^ 2 = x ^ 2 + y ^ 2[/tex]
Then we replace the value of the radius in the equation and we have to::
[tex]x ^ 2 + y ^ 2 = 6 ^ 2[/tex]
Then [tex]r = 6[/tex] in rectangular coordinates is a circle centered on the point (0,0) and with a constant radius [tex]r = 6[/tex].
(b) [tex]r = 2cos(\theta)[/tex]
The radius is not constant, the radius depends on [tex]\theta[/tex].
To convert this equation to rectangular coordinates we write
[tex]r = 2cos(\theta)[/tex] Multiply both sides of the equality by r.
[tex]r ^ 2 = 2 *rcos(\theta)[/tex] remember that [tex]x = rcos(\theta)[/tex], then:
[tex]r ^ 2 = 2x[/tex] remember that [tex]x ^ 2 + y ^ 2 = r ^ 2[/tex], then:
[tex]x ^ 2 + y ^ 2 = 2x[/tex] Simplify the expression.
[tex]x ^ 2 -2x + y ^ 2 = 0[/tex] Complete the square.
[tex]x ^ 2 -2x + 1 + y ^ 2 = 1[/tex]
[tex](x-1) ^ 2 + y ^ 2 = 1[/tex] It is a circle centered on the point (1, 0) and with radio [tex]r=1[/tex]

3/7 of the apples in a box are red apples. The rest are green apples. There are 24 Green apples. How many apples are there altogether?
After spending 2/5 of his money on a toy car, Josh had $42 left. How much money did he have first?
Answer:
42 apples altogether; $70
Step-by-step explanation:
If 3/7 of the apples in a box are red, that means 4/7 of the apples in the box are green. This means that (4/7)x=24 (x=number of apples altogether), since 24 of the apples are green. The equation can then be solved by dividing 24 by 4/7, giving us 42.
x=42
If Josh spent 2/5 of his money and had $42 dollars, $42 would be 3/5 of his money. This means that (3/5)x=42 (x= amount of money he started with). The equation can be solved by dividing 42 by 3/5, which gives us 70.
x=70
there were 42 apples in total and josh initially had $70.
Finding Total Number of ApplesLet the total number of apples be x. Therefore, [tex]\frac{4}{7}[/tex] of x are green apples, and this equals 24:
[tex]\frac{4}{7} \times x = 24[/tex]
We can solve for x as follows:
[tex]x = 24 \times \frac{7}{4}\\\\x = 42[/tex]
So, there are 42 apples in total.
Finding Initial Amount of MoneyLet y represent the total amount of money Josh had initially. According to the problem, after spending [tex]\frac{2}{5}[/tex] of his money, he had [tex]\frac{3}{5}[/tex] remaining, which equals $42:
[tex]\frac{3}{5} \times y = 42[/tex]
Now we can solve for y as follows:
[tex]y = 42 \times \frac{5}{3}\\\\y = 70[/tex]
Josh initially had $70.
So, there were 42 apples in total and josh initially had $70.

Find the greatest common factor of 8a 3 b 2 and 12ab 4.
Answer:
[tex]2^{2} \times a \times b^{2}=4ab^{2}[/tex]
Step-by-step explanation:
Greatest common factor of two or more terms is the largest(greatest) possible term which exactly divides all the given term. For example the greatest common factor of 20 and 30 is 10 as 10 is the largest possible number that can exactly divide 20 and 30 without leaving any remainder. GCF is found as the product of all the common factors
Given terms are:
[tex]8a^{3} b^{2} =2^{3}\times a^{3}\times b^{2}[/tex]
[tex]12ab^{4}=4 \times 3 ab^{4} =2^{2} \times 3 \times a \times b^{4}[/tex]
From the above factors we can see that the common factors are:
[tex]2^{2} , a , b^{2}[/tex]
Therefore, the greatest common factor will be:
[tex]GCF=2^{2} \times a \times b^{2}=4ab^{2}[/tex]
The greatest common factor of 8a³b² and 12ab⁴ is 4ab², found by identifying the smallest powers of the common factors in each term.
To find the greatest common factor (GCF) of the given terms, we need to identify the highest power of each variable that appears in both terms.
The prime factorization of 8 is [tex]\(2^3\)[/tex], and the prime factorization of 12 is [tex]\(2^2 \times 3\)[/tex]. Thus, the greatest common factor of the coefficients is [tex]2^2 = 4.[/tex]
For the variables a and b:
- [tex]\(a^3\)[/tex] appears in the first term.
- a appears in the second term.
- [tex]\(b^2\)[/tex] appears in both terms.
So, the greatest common factor of [tex]\(a^3 b^2\) and \(ab^4\) is \(ab^2\).[/tex]
Therefore, the greatest common factor of [tex]\(8a^3 b^2\) and \(12ab^4\) is \(4ab^2\).[/tex]
Given: m∠EYL=72° Find: m EHL , m LVE .
Answer:
m(ARC)EHL: 108°
m(ARC)LVE: 252°
Step-by-step explanation:
Hey, so initially, we should start off with some stuff:
The sum of the arcs add up to 360°
m∠EYL=72°
We can create a system and use substitution to find the measure of an arc we don't know.
Step 1: We can use the 'Secants exterior angle theorem' to help us find the measure of (ARC)EHL.
<EYL=1/2((ARC)EVL-[ARC]EHL) (the theorem)
Step 2: By using substitution, we can say that (ARC)EVL=360°-(ARC)EHL
Thus, when we substitute it back into the theorem, the answer will be <EYL=1/2((360°-(ARC)EHL)-(ARC)EHL)=72°
Step 3: When we solve this out (and you can replace (ARC)EHL with x when solving), you will get an answer of x=108° or (ARC)EHL=108°.
Step 4: (ARC)LVE will be equal to 360°-m(ARC)EHL, which, when we substitute, will be 360°-108°, which will come out to be 252°.
Therefore, by algebra, substitution, and part-whole-postulate, (ARC) LVE=252°.

Annie bought 3/4 kg of cocoa powder, which cost $12.92 per kg.
* Estimate the cost.
b. Find the exact amount she had to pay
Answer:
Estimated cost; $9
Exact amount; $9.69
Step-by-step explanation:
We are told that Annie bought 3/4 kg of cocoa powder, which cost $12.92 per kg.
a.
We are required to estimate the cost of the 3/4 kg of cocoa powder given that 1 kg costs 12.92
We can round down the cost of a kg to obtain $12 per kg. Therefore, 3/4 of a kg will cost approximately;
(3/4) of 12
= (3/4)*12 = $9
Thus the estimated cost is $9
b.
We are required to determine the the exact amount she had to pay for the 3/4 kg of cocoa powder;
1 kg cost 12.92
3/4 of a kg will cost;
(3/4) of 12.92
= (3/4) * 12.92
Using a calculator we have;
9.69
Therefore, the exact amount paid was $9.69
Answer:
Part a) The estimate cost is about $9
Part b) The exact cost is $9.69
Step-by-step explanation:
we know that
Annie bought 3/4 kg of cocoa powder, which cost $12.92 per kg
Part a
To find the estimate cost round the numbers and multiply
we have
[tex]\$12.92=\$12[/tex] -----> round down
so
[tex]\frac{3}{4}(12)=\$9[/tex]
Part b
To find the exact amount she had to pay, multiply 3/4 by $12.92
so
[tex]\frac{3}{4}(12.92)=\$9.69[/tex] ----> exact value

1/6, 1/3, 2/3
Step-by-step explanation:
Given data:
The sum of the first three terms of a finite geometric series is7/6 and their product 1/27 is .
Let a/r , a and ar be the three terms of a finite geometric series then:
a/r + a + ar = 7/6
and
(a/r) x (a) x (ar) = 1/27
Now first solving for a:
solving second equation
a^3r/r = 1/27
a^3= 1/27
a = 1/[tex]\sqrt[3]{27}[/tex]
a=1/3
Now solving for r:
Solving first equation
a/r + a + ar = 7/6
Putting value of a= 3 in above equation
1/3r + 1/3 + r/3 = 7/6
(1+r+r^2)/3r= 7/6
6(1+r+r^2)= 7(3r)
6+ 6r+ 6r^2= 21r
6r^2 - 15r +6=0
r=2
Hence the first three terms of a finite geometric series are
a/r= (1/3)/(2)
= 1/6
a= 1/3
ar= 1/3 (2)
=2/3 !
