The vertical line graph shows how often each number on a standard dice comes up. What percentage of rolls were a 6?
Answers
Answer:
21%
Step-by-step explanation:
Out of the 25 + 9 + 12 + 21 + 12 + 21 = 100 total rolls, 6 came up 21 times so the percentage is 21/100 = 21%.

It is true that the triangles shown in the diagram are congruent triangles.
What are congruent triangles?Two triangles are considered to be congruent triangles if two triangles have similar sizes and shapes. This implies that two triangles are defined to be congruent if the lengths of their individual sides and angles are the same.
The angle-angle-side (AAS) theorem states that when two angles and any side of a triangle are identical to two angles and any side of some other triangle, then the triangles are considered to be congruent triangles.
Therefore, since these assertions are true of the triangles given, we can conclude that the two triangles are congruent triangles.

A $20,000 investment earned a simple interest rate of 5.4%. How much interest was earned in one year?
Answers
Answer:
18,920.00
Step-by-step explanation:
discount = x
original price = $20,000
discount% = 5.4%
x/20,000 = 5.4/100
x · 100 = 5.4 · 20,000
100x = 108,000
100x/100 = 108,000/100
x = $ 1,080.00
Sale price = original $ - discount $ = final answer
$20,000 - $1,080 = $18,920.00
Answer:1,080
Step-by-step explanation:

Can a right triangle have the measurements of 8,11, and 13?
Answers
Answer:
yes it can
Step-by-step explanation:
yes
Answer:
No
Step-by-step explanation:
You need to use the Pythagorean Theorem. This will show you if the ratio between the sides is accurate.
a² + b² = c²
8² + 11² = 13²
64 + 121 = 169
185 ≠ 169
The measurements will not fit in a right triangle.

To make one cheese sandwich, Tina uses one bread roll and two cheese slices.
Pack of 15 bread rolls
£1.91
Pack of 20 cheese slices
£2.23
She is going to buy enough packs to
have exactly twice as many cheese slices as bread rolls
make more than 100 cheese sandwiches.
Work out the least amount she can spend.
Answers
Answer:
£42.04 is the correct answer.
Step-by-step explanation:
Cost of pack of 15 bread rolls = £1.91
Cost of pack of 20 cheese slices = £2.23
She has to buy exactly twice as many cheese slices as bread rolls.
She has to make more than 100 cheese sandwiches.
Number of bread rolls required for 100 bread rolls.
Minimum 15[tex]\times[/tex]7 = 105 bread rolls are to be bought.
105 bread rolls mean 210 cheese slices but it is a pack of 20 cheese slices.
So, at least 220 cheese slices can be bought.
But, 220/2 = 110 bread rolls are not possible to be bought.
So, at least 120 (15 [tex]\times[/tex] 8 i.e. 8 packs) bread rolls have to be bought and 120 [tex]\times[/tex] 2 = 240 (20 [tex]\times[/tex] 12 i.e. 12 packs) of sandwiches have to be bought.
So, minimum amount to be spent for at least 100 cheese sandwiches
= 1.91 [tex]\times[/tex] 8 + 2.23 [tex]\times[/tex] 12 = £42.04

Brady and 3 friends went to lunch at Mazzio’s Pizza. Their meal cost $32, and they left a 15% tip. How much was the total bill, including tip? Can someone please explain it to me how to do it?
Answers
Answer: $36.8
Step-by-step explanation:
From the question, we are told that Brady and 3 friends went to lunch at Mazzio’s Pizza and that their meal cost $32, and they left a 15% tip. Their total bill will be $32 plus 15% of $32. This can be written mathematically as:
= $32 + (15% of $32)
= $32 + (15/100 × $32)
= $32 + (0.15 × $32)
= $32 + $4.8
= $36.8
Their total bill is $36.8

Justin packed two suitcases for his trip and compared the weights of the items he packed in each of the suitcases. A number line goes from 0 to 36. Suitcase 1's whiskers range from 4 to 30, and the box ranges from 8 to 12. A line divides the box at 9. Suitcase 2's whiskers range from 2 to 20, and the box ranges from 5 to 18. A line divides the box at 7. Which statement is true about the box plots? The data for suitcase 1 have an outlier, but the data for suitcase 2 does not. The data for suitcase 2 have a greater median than the data for suitcase 1. The data for suitcase 1 has a greater interquartile range than the data for suitcase 2. The data for suitcase 2 has a greater range than the data for suitcase 1.
Answers
Answer:
The correct option is;
The data for suitcase 1 have an outlier but the data for suitcase 2 does not
Step-by-step explanation:
Range of a box plot
Interquartile range (IQR) for bot suitcases we have
Here we have for suitcase 1
IQR = Q₃ - Q₁ = 12 - 8 = 4
For suitcase 2
IQR = Q₃ - Q₁ = 18 - 5 = 13
Lower outlier = Q₁ - 1.5×IQR
Higher outlier = Q₃ + 1.5×IQR
For suitcase 1 we have;
Lower outlier = 8 - 1.5×4 = 2 (No lower outlier)
Higher outlier = 12 + 1.5×4 = 18
Hence, whereby the whiskers range from 4 to 30, suitcase 1 has a higher outlier
For suitcase 2 we have;
Lower outlier = 5 - 1.5×13 = -14.5 (No lower outlier)
Higher outlier = 18 + 1.5×13 = 37.5
Hence, whereby the whiskers range from 2 to 20, suitcase 2 has no outlier.
Therefore, the correct option is the data for suitcase 1 have an outlier but the data for suitcase 2 does not.

A potato was launched in the air using a potato gun. The function for the situation was h(t)=-16t^2 +100t+10, where t was the time in seconds and h is the height in ft. What was the maximum height? What was the lowest height of the potato? What was the lowest times that applies to the actual situation? What is the greatest time that applied to the situation? What are the domain and range of the function using set builder notation?
Answers
Answer:
The height equation is:
h(t)=-16t^2 +100t+10
A) To find the maximum height, we must find the time where the velocity is 0, so we must derive it with respect to the time.
v(t) = -2*16*t + 100 = 0
t = 100/(2*16) = 3.125s
Now we put this time in our height equation:
h(3.125s) = -16*3.125^2 + 100*3.125 + 10 = 166.25 ft.
B) The lowest heigth of the potato will be h = 0ft, when the potato hits the ground.
C) the lowest time that works for that function is t = 0s, when the potato is fired by the gun.
D) the maximum time can be finded when the potato hits the ground, afther that point the equation does not work anymore, let's find it,
h(t) = 0 = -16t^2 +100t+10
we can solve it using Bhaskara's equation:
[tex]t = \frac{-100 +- \sqrt{100^2 +4*16*10} }{-2*16} = \frac{-100 +- 103.2}{-32}[/tex]
So the two solutions are:
t = 6.3s
t = -0.1s
We need to chose the positive time, as we already discused that the minimum time that works for the equation is t = 0s.
so here the answer is t = 6.3s
E) the domain is 0s ≤ t ≤ 6.3s
The range is 0ft ≤ h ≤ 166.25 ft.
