Question Help
Elizabeth brought a box of donuts to share. There are two-dozen (24) donuts in the box, all identical in size, shape and color. Two are jelly-filled, 5 are lemon-filled,
and 17 are custard-filled. You randomly select one donut, eat it, and select another donut. Find the probability of selecting two custard-filled donuts in a row.
(Type an integer or a simplified fraction.)
Answer:
34/69
Step-by-step explanation:
2 are jelly-filled
5 are lemon-filled
17 are custard-filled
Total: 24
First drawing:
There are 24 donuts in total, 17 of which are custard filled.
p1(custard filled) = 17/24
Second drawing:
There are now a total of 23 donuts, 16 of which are custard filled.
p2(custard) = 16/23
The two drawings are independent events, so the overall probability is the product of the individual probabilities.
Overall probability of drawing two custard filled donuts:
p(2 custard filled) = p1 * p2 = 17/24 * 16/23 = 17/3 * 2/23 = 34/69

In ΔLMN, m∠L = 108°, m∠M = 25°, and ℓ = 12. What is m?
Answer:
m = 5.33
Step-by-step explanation:
First we need to calculate angle N.
Sum of angles in a triangle is 180°
∠L + ∠M + ∠N = 180°
108°+25°+∠N = 180°
∠N = 180°-(108°+25°}
∠N = 180°-133°
∠N = 47°
Given side l = 12, to get m, we will use the sine rule.
l/sinL = m/sinM = n/sinN
12/sin108° = m/sin25°
m × sin108°= 12sin25°
m = 12sin25/sin108°
m = 5.071/0.951
m = 5.33

How can you find 10% of any number without multiplying or dividing?
Answer:
subtract ---------
Step-by-step explanation:
To find value of the percentage of the number 10% of any number X without multiplying or dividing, divide X by 100 to get 1% and then multiply it by 10.
Let's say we want to find 10% of a number X. The key to this method lies in understanding that finding 10% of a number is the same as finding 1% of that number and then multiplying it by 10. To find 1% of X, we can divide X by 100, as 1% is equivalent to dividing by 100.
Step 1: Finding 1% of the number
1% of X = X / 100
Step 2: Finding 10% of the number
To get 10% of X, we multiply the 1% value by 10 since 10% is ten times greater than 1%.
10% of X = (X / 100) * 10
Now, let's demonstrate this method with an example:
Let's find 10% of 250.
Step 1: Finding 1% of 250
1% of 250 = 250 / 100 = 2.5
Step 2: Finding 10% of 250
10% of 250 = (2.5) * 10 = 25
So, 10% of 250 is 25.

A random survey was taken of 400 people in a city in the United States. The survey found that the three most common eye colors are brown, blue, and hazel. Out of the 400 people in the survey, 167 have brown eyes, 132 have blue eyes, and 57 have hazel eyes. Using the survey results, what is the probability that a person has brown or hazel colored eyes? *
A. 189/400 (47.25%)
B. 14/25 (56.00%)
C. 167/400 (41.75%)
D. 57/400 (14.25%)
Answer:
B 14/25(56.00%)
Step-by-step explanation:
167+57=224, which means 224/400(56.00%) people would have brown or hazel eyes. 224/400 is also equivilant to 14/25
a trucker drove 500 miles in h hours. If the trucker averaged 60 mph, which linear equation could be used to find the number of hours that the trucker drove?
Step-by-step explanation:
Given that,
Distance covered by a trucker, d = 500 miles
Average speed of the trucker, v = 600 mph
A trucker drove 500 miles in h hours. We need to write the linear equation used to find the number of hours that the trucker drove. Average speed is given by :
[tex]v=\dfrac{d}{t}[/tex]
t is time in hours
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{500\ miles}{60\ mph}[/tex]
If t is h hours,
[tex]h=\dfrac{500\ miles}{60\ mph}\\\\500=60h[/tex]
On solving, h = 5 hours.
Hence, this is the required solution.
solve the equation. use the calculator if you need to, and round the solution to the nearest tenth
0.75p=0.4+100
Answer:
p=133.866667
Step-by-step explanation:
Let's solve your equation step-by-step.
0.75p=0.4+100
Step 1: Simplify both sides of the equation.
0.75p=0.4+100
0.75p=(0.4+100)(Combine Like Terms)
0.75p=100.4
0.75p=100.4
Step 2: Divide both sides by 0.75.
0.75p/0.75 = 100.4/0.75
p=133.866667
Answer:
p=133.866667

This composite figure has been divided into three rectangles. What is the area of this composite figure
Given:
A composite shape consisting of three rectangles with different lengths and widths.
To find:
The area of the composite shape.
Solution:
To find the area of the composite shape we must add the areas of all the three rectangles.
The upper rectangle has a length of 8 inches and a width of 4 inches.
The area of a rectangle [tex]= (l)(w).[/tex]
The area of the upper rectangle [tex]=(8)(4)=32[/tex] in².
The middle rectangle has a length of [tex]8-4=4[/tex] inches and a width of [tex]10-4-1.5=4.5[/tex] inches.
The area of the middle rectangle [tex]=(4)(4.5) = 18[/tex] in².
The lower rectangle has a length of 8 inches and a width of 1.5 inches.
The area of the lower rectangle [tex]= (8)(1.5)=12[/tex] in².
The area of the composite shape [tex]= 32+18+12 = 62[/tex] in².
The composite shape has an area of 62 in² which is option 3.
Answer: you have to do 62

Answer: I think the table has the greater rate of change because to find the greater rate of change we have to find the rate of change for both function. So, for this we have to find two points for both and then using the slope formula we have to solve for it.
for the first one: (4,6)(6,9)
9-6/6-4
3/2
For the second function: (4,5)(5,10)
10-5/5-4
5/1
5
so as we see that 3/2 is not greater than 5 so the function 3 has the greater one.
I don't know how to solve the first one. I am sorry but hope this helps you!
Find the total total surface area of the composite figure below with
r=2.2
l=10.2
h=8.7
Use 3.14 for LaTeX: \piπ.
Round to the nearest hundredth.
Pro tip: don't count the surfaces that are not exposed.
Given:
The radius of given fig = 2.2 unit
The height of the cylindrical part = 8.7 unit
The slant height of the cone = 10.2 unit
To find the total surface area of the given figure.
Formula
The given figure consists of a cylinder and a cone.
So, the surface area of the fig
[tex]SA = \pi r l+2\pi r h+\pi r^{2}[/tex]
Where, r be the radius
h be the height
l be the slant height
Now,
Putting,
r=2.2, h = 8.7, l=10.2 and π=3.14 we get,
[tex]SA = (3.14)(2.2)(10.2)+2(3.14)(2.2)(8.7)+(3.14)(2.2^{2} )[/tex] sq unit
or, [tex]SA = 70.4616+120.1992+15.1976[/tex] sq unit
or, [tex]SA = 205.8584[/tex] sq unit
or, [tex]SA = 205.86[/tex] sq unit
Hence,
The total surface area of the given figure is 205.86 sq unit.

A school bought pens, each costing $1, and pencils, each costing $0.5. The cost of the whole purchase was $220. How many pens and pencils were purchased if there were 80 more pencils than pens?
Answer:
120 pens and 200 pencils.Explanation:
You can set a system of two equations.
1. Variables
x: number of pensy: number of pencils2. Cost
each pen costs $1, then x pens costs: xeach pencil costs $0.5, then y pencil costs: 0.5yThen, the total cost is: x + 0.5yThe cost of the whole purchase was $ 220, then the first equation is:x + 0.5y = 220 ↔ equation (1)
3. There were 80 more pencils than pens
Then:
pencils = 80 + pens
↓ ↓
y = 80 + x ↔ equation (2)
4. Solve the system
i) Substitute the equation (2) into the equation (1):
x + 0.5(80 + x) = 220ii) Solve
x + 40 + 0.5x = 2201.5x = 180x = 180/1.5x = 120 pensiii) Substitute x = 120 into the equation (2)
y = 80 + 120y = 200 pencilsSolution: 120 pens and 200 pencils ← answer
Graph the line x=-2y-3. Find the
slope and the y-intercept.
Answer:
the slope is [tex]-\frac{1}{2}[/tex]
the y-intercept is [tex](0,-1.5)[/tex]
Step-by-step explanation:
(the website i used to graph it is called desmos)
After you graph the line, the y-intercept is the point on the line where it passes through the y-axis. On this line, that point is [tex](0,-1.5)[/tex]
To find the slope, an easy way would be to use "rise over run"
Find two points on the line and plug them into this equation: [tex]\frac{y_{1} -y_{2} }{x_{1} -x_{2} }[/tex], for this i used the points [tex](5,-4)[/tex] and [tex](7,-5)[/tex]
[tex]\frac{-4+5}{5-7} = -\frac{1}{2}[/tex]
so the slope is [tex]-\frac{1}{2}[/tex]
