=120units sq
Step-by-step explanation:
The semi-perimeter is:
s = (a + b + c) / 2
= (10 + 24 + 26) / 2
= 47
We will find the area of the triangle using the Heron's formula.
A = √[s (s - a) (s - b) (s - c)]
= √[47 (47 - 10) (47- 24) (47 - 26)]
= √10 × 37 × 23 × 21
= √ 56513

PLEASE HELPP ASAP Gavin has two bags of titles. The number and colors of the titles are shown in the table. If Gavin randomly draws one tile from each bag what is the probability that he will select two black tiles?
Answers
Answer:
the answer is 7/27 cause you find the total number of tiles and total number of black tile then put it in the ratio of :
total no of black tiles/ total tiles
Answer:
The answer is 7/27
Step-by-step explanation:
For this you will be using What you want over the total of what you have. Sum all the things which gives you: 27 in total.
You want only the black ones, so add 3+4 and you get 7
What you want is the black (7) over the total amount you have (27)

The circumference of a circle is 50.24 meters.
What is the diameter, in meters? Use 3.14 for π and round to the nearest meter, if necessary.
Answers
We know that ,
Circumference is a circle = 2 pi r
=> 2 pi r = 50.24
=> r = 50.24/2 x 3.14
=> r = 78.8 m
But to find diameter , d = 2 x radius => 2 x 78.8 = 157.73 which is approximately 158
Option d is correct
circumference=radius*2*3.14
50.24=r*2*3.14
1. divide 50.24 by 2
2. divide that answer by 3.14
3. this leaves you with the radius. multiply by 2 for the diameter

For n ≥ 4 , suppose n² ≤ 2ⁿ and prove that (n+1)² ≤ 2ⁿ⁺¹

Since n² ≤ 2ⁿ (according to the hypothesis) and we know that 2n + 1 ≤ 2ⁿ

Turtles can live a long time. This stem-and-leaf plot shows the ages (in years) of the turtles in the reptile house of the Kalamazoo Zoo:
A box turtle and a map turtle escape from the reptile house of the Kalamazoo Zoo. The box turtle is older than the map turtle. The average age of the turtles remaining at the zoo after the escape is 1 year less than the average age before the escape.
What is the age of the escaped box turtle?
Answers
Answer:
1,1,2,5,6,7,10,10,13, 18, 19, 20, 24, 26, 27, 31, 36, 54, 63, 67
The average age is 22 yrs
The sum of the ages is 440 yrs
When two of the turtles leave, the average is 21 yrs....and there are 18 turtles left
So....the sum of the ages is 21 * 18 = 378
And the difference in the sums is 62
The only two values that sum to 62 are 26 and 36
So.....the box turtle must have been 36 and the map turtle must have been 26
Step-by-step explanation:
The age of the escaped box turtle is 36 years in the reptile house of the Kalamazoo Zoo.
What is the stem-and-leaf diagram?A stem-and-leaf diagram is a quantitative assessment of a collection of data in which the data values are divided into a "stem" (the first digit of the number) and a "leaf" (the remainder of the number) (the last digit of the number).
This stem-and-leaf plot shows the ages (in years) of the turtles in the reptile house of the Kalamazoo Zoo:
1,1,2,5,6,7,10,10,13, 18, 19, 20, 24, 26, 27, 31, 36, 54, 63, 67
To find the age of the escaped box turtle, we can first find the average age of all the turtles before the escape. To do this, we can add up all the ages and divide by the number of turtles:
(1+1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63+67)/20 = 26
The average age of the turtles remaining at the zoo after the escape is 1 year less than the average age before the escape, so the average age of the turtles remaining at the zoo is 26 - 1 = 25 years.
To find the age of the escaped box turtle, we need to subtract its age from the average age of the remaining turtles.
Let's represent the age of the box turtle X. We can set up the equation:
(1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63+67 - X)/19 = 25
We can solve this equation by multiplying both sides by 19 and then subtracting 67 from both sides:
1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63 - X = 475
Then we can add X to both sides to get:
1+2+5+6+7+10+10+13+18+19+20+24+26+27+31+36+54+63 -X + X = 475 + X
This simplifies to:
X = 36
Therefore, the age of the escaped box turtle is 36 years.

If we consider only the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?
Answers
Answer:
20%
Step-by-step explanation:
Method 1
Percentage of people who preferred red:
= 13%
Percentage of people who named a rainbow color:
= 13 % + 4% + 5% + 15% + 16% + 12%
= 65%
Percentage of people who preferred red from those who named a rainbow color:
= (13% ÷ 65%) × 100
= 20%
Method 2
Number of people who preferred red:
= 13% of 500
= 13% × 500
= 0.13 × 500
= 65
Percentage of people who named a rainbow color:
= 13 % + 4% + 5% + 15% + 16% + 12%
= 65%
Number of people who named a rainbow color:
= 65% of 500
= 65% × 500
= 0.65 × 500
= 325
Percentage of people who preferred red from those who named a rainbow color:
= (number who preferred red ÷ number named rainbow color) × 100
= (65 ÷ 325) × 100
= 20%
Pls Brainliest!
Answer:
20%
Step-by-step explanation:
The rainbow colors add up to 13 + 4 + 5 + 15 + 16 + 12 = 65 percent of the pie chart. So, 65% ∙ 500 = 325 people in the survey named a rainbow color. Of these, 13% ∙ 500 = 65 named red.
Therefore, if we consider only the 325 people who named a rainbow color, the percentage of those people who preferred red is
65/325 = 1/5 = 20%
(You may notice that the answer would still be 20% even if the total number of people in the survey were some number other than 500. This is because 13% is 20% of 65%, no matter what these are percentages of!)

What is the total cost of the cleaning service?
Enter your answer in the box.

Step-by-step explanation: To find the cost of the supplies we multiply $54 by .3 (the decimal version of 30%). The total is 16.2 . If we subtract this from the total amount we find the cost of the cleaning service. 54-16.2 = 37.8

87.92 in³
175.84 in³
95.18 in³
Answers
Answer:
87.92 in^3
Step-by-step explanation:
Formula for finding the volume of a cylinder:
V=Bh
B= area of the base
h= height
Diameter=4 radius=2 The radius is half of the diameter
The base of a cylinder is a circle, so you would find the area of the circle and multiply it by the height of the cylinder.
V= (3.14*2^2)7
V= (3.14*4)7
V= 12.56(7)
V= 87.92 in^3
Answer:
The answer to this question should be b. 87.92 in^3 because the formula to find the volume of a cylinder is V=TTr^2h. and remember that the radius is half of the diameter so back to the question.
We multiplied 3.14 times 4 because remember that the radius is half of the diameter and we get 2 but remember the exponent so we need to multiplied to the second power 2 times 2 and we get 4 so when we multiplied 3.14 times 4 we get 12.56 and when we multiplied 12.56 times the height which is 7 we get 87.92 so check the choices and see if there is an answer and yes there is so b which is 87.92in^3 is hopefully the correct answer.

What is the sum of an arithmetic sequence?Let a₁ be the first term, L be the last term, n be the number of terms, and d be a common difference.
Then the sum of the arithmetic sequence will be
S = (n / 2)[a₁ + L]
S = (n/2) [2a + (n − 1) d]
A pile of logs has 24 logs in the bottom layer, 23 in the second layer, 22 in the third, and so on. The top layer contains 10 logs.
The common difference is negative 1.
Then the nth term of the arithmetic sequence is given as,
10 = 24 + (n - 1) x (-1)
n - 1 = 14
n = 15
Then the total number of logs in the pile will be
S = (15/2) [24 + 10]
S = 7.5 x 34
S = 255
The total number of logs in the pile will be 255.
