Answer:

Answer:
806 in^2
Step-by-step explanation:
we can start by breaking it up into two 11x13 sides and four 13x10 sides.
A=l*h
The first group of just two sides is 13*11 = 143, and for both sides 286 in^2
Then for the second group, 13*10 = 130, and for four sides, 520 in^2
We can add these values together for the total surface area, and we'll get 806 in^2 !

Given:
The right angle triangle with legs 4 units and 7 units.
To find:
The length of hypotenuse.
Solution:
Pythagoras theorem: In a right angle triangle,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
Let x be the length of the hypotenuse.
Using the Pythagoras theorem for the given triangle, we get
[tex]x^2=4^2+7^2[/tex]
[tex]x^2=16+49[/tex]
[tex]x^2=65[/tex]
Taking square root on both sides, we get
[tex]x=\sqrt{65}[/tex] [∵Side length cannot be negative]
[tex]x\approx 8.06[/tex]
Therefore, the length of the missing side for the given right angle triangle is 8.06 units.

Pick a red marble: 8/24 or 1/3
Pick a blue marble: 10/24 or 5/12
Pick red or white: 14/24 or 7/12

The sum of two numbers is 41. The larger number is 21 more than the smaller number. What are the numbers
Answers
Step-by-step explanation:
a+b=41
let larger number be a and smaller be b
a=21+b
placing value of a in a+b=41
21+b+b=41
2b=41-21
b=20÷2
b=10
so a=21+10
=31
the numbers are 21 and 10.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, The sum of two numbers is 41.
let "x" be the smallest number.
Since The larger number is 21 more than the smaller number.
thus,
the larger number = 21 + smaller number
The larger number = 21 + x
Thus, sum = 41
x + 21 + x = 41
2x = 20
x = 10
So,
the Largest number = 21 + 10
Therefore, The largest number and the smallest number are 21 and 10 respectively.

On the same exam, Alyssa's friend Jessie answered three times more questions correct than incorrect. Who got a higher percentage of the test questions correct, Alyssa or Jessie?
Answers
Complete question is;
Alyssa took a math test with 20 questions and she answered 16 questions correctly. In order get an A, she needs to answer at least 90 percent of the questions correctly.
A) Did Alyssa get an A on this math test? Explain.
B) How many questions would Alyssa need to answer correctly in order to get an A?
C) On the same exam, Alyssa's friend Jessie answered three times more questions correct than incorrect. Who got a higher percentage of the test questions correct, Alyssa or Jessie
Answer:
A) she didn't get an A because she scored less than 90%.
B) She will need to answer 18 correctly to get an A.
C) Alyssa had a higher percentage.
Step-by-step explanation:
A) Alyssa answered 16 out of 20 questions correctly.
Converting this to percentage gives;
16/20 × 100% = 80%
Now,we are told she needs at least 90% correct answers to get an A.
She scored 80% which is less than 90% mark of A, therefore she didn't get an A.
B) Let the number of minimum questions to answer correctly out of 20 be x.
Thus, since it is 90%.
Then;
x/20 × 100% = 90%
making x the subject;
x = 90 × 20/100
x = 18
She will need to answer 18 correctly to get an A.
C) her friend Jessie answered three times more questions correct than incorrect.
This means for every 4 questions answered, she had 3 correct and 1 incorrect.
Thus,
For 4 questions she had 3 correct answers, then for 20 questions, she will have: 20 × 3/4 = 15 correct questions
Which corresponds to;
15/20 × 100% = 75%
Thus, Alyssa had a higher percentage.

Roberto debe leer un libro que contiene 340 páginas en 4 días por lo cual planea la siguiente distribución: el primer día 1/5 de las páginas del libro, el segundo 1/4 de lo que queda por leer y el tercero 1/6 del resto. ¿Cuántas páginas le quedan por leer a Roberto en el cuarto día?
Answers
Answer:
170 pages
Step-by-step explanation:
Roberto must read a book that contains 340 pages in 4 days for which he plans the following distribution
The number of pages he read for the first day :
The first day 1/5 of the pages of the book
This is calculated as:
1/5 × 340 pages
= 68 pages
For the second day:
The second 1/4 of what remains to be read
The number of pages remaining after the first day is calculated as:
340 - 68 = 272 pages
Hence, the number of pages read on the second day is
1/4 × 272 pages
= 68 pages
For the third day
One the third day, 1/6 of the rest was read.
The number of pages remaining after the first day is calculated as:
272 - 68 = 204 pages
Hence, the number of pages read on the third day is
1/6 × 204 pages
= 34 pages
Therefore, the number of pages Roberto has to read on the fourth day is calculated as:
340 pages - (68 + 68 + 34)pages
340 pages - 170 pages
= 170 pages
