9514 1404 393
Answer:
36
Step-by-step explanation:
We assume that time is inversely proportional to the number of workers. So increasing the number of workers by a factor of 121/99 = 11/9 will decrease the number of days by a factor of 9/11.
(9/11)(44 days) = 36 days
It will take 36 days to complete the construction with 121 workers.

Answer:
287.25 miles in 5.75 hours
Step-by-step explanation:
so he was first driving at 48mph because 168/3.5=48
5 miles per hour faster than that is 53mph
53*2.25=119.25
then we add 119.25 and 168
The distance from Cherotich's home to school is
2km 400m. He goes to school in the morning
and returns in the evening daily. What distance
does he cover from Monday to Friday?
Answer:
24 kilometers
Step-by-step explanation:
Given
Represent the distance with x
[tex]x = 2km\ 400m[/tex]
Required
The distance covered for 5 days (i.e. Monday to Friday)
First, we calculate the distance covered in a day
He covers the same distance when going to school and when coming back from school.
So, the daily distance is:
[tex]Daily = 2 * x[/tex]
[tex]Daily = 2 * (2km\ 400m)[/tex]
[tex]Daily = 4km\ 800m[/tex]
In 5 days, he covers:
[tex]5\ days = 5 * Daily[/tex]
[tex]5\ days = 5 * (4km\ 800m)[/tex]
[tex]5\ days = 5 * (4km+ 800m)[/tex]
Open bracket
[tex]5\ days = 5 * 4km+ 5 * 800m[/tex]
[tex]5\ days = 20km+ 4000m[/tex]
Convert m to km
[tex]5\ days = 20km+ 4km[/tex]
[tex]5\ days = 24km[/tex]

Whats the answer to these? (These are called Proper fractions.)
Jeremiah ran for 3/10 of a mile and then walked another 2/5 of a mile. How far did he travel in all?
Daniel read 4/5 books and Edgar read 1/2 books. How many more books did Daniel read than Edgar?
Jared drove 2/8 miles to the restaurant. He drove another 1/4 miles to the mall. How many miles did he drive in all?
Answer to the first question: 7/10ths of a mile
Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: [tex]\frac{2*2}{5*2} = \frac{4}{10}[/tex]. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.
Answer to the second question: Daniel read three (3/10) more books
Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: [tex]\frac{4*2}{5*2} = \frac{8}{10}[/tex]. For Edgar, that would mean: [tex]\frac{1*5}{2*5} = \frac{5}{10}[/tex]. So, Daniel read 3 more books than Edgar.
Answer to the third question: 2/4 mile (or 1/2 a mile)
Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.
Answer and Step-by-step explanation:
1. Convert [tex]\frac{2}{5}[/tex] to have a denominator of 10.
[tex]\frac{2}{5}[/tex] × [tex]\frac{2}{2}[/tex] = [tex]\frac{4}{10}[/tex]
[tex]\frac{3}{10} + \frac{4}{10} = \frac{7}{10}[/tex]
Jeremiah ran [tex]\frac{7}{10}[/tex] of a mile in total.
2. Convert the denominators of all the fractions to have a 10.
[tex]\frac{1}{2}[/tex] × [tex]\frac{5}{5} =\frac{5}{10}[/tex]
[tex]\frac{4}{5}[/tex] × [tex]\frac{2}{2} = \frac{8}{10}[/tex]
Daniel read [tex]\frac{3}{10}[/tex] more books than Edgar, since 8 books is more than 5 books by 3 books.
3. Convert [tex]\frac{1}{4}[/tex] to have a denominator of 8.
[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{2} = \frac{2}{8}[/tex]
[tex]\frac{2}{8} +\frac{2}{8}= \frac{4}{8}, or\frac{1}{2}[/tex]
Jared drove [tex]\frac{4}{8}[/tex], or [tex]\frac{1}{2}[/tex] miles in total.

A triangular pen is modeled by △ABC. The vertices of △ABC are A(0, 8), B(12, 3), and C(7, –9). What is the area of the pen?
Answer:
The area of the triangle is 84.511 square units.
Step-by-step explanation:
First step, we need to calculate lengths of line segments AB, BC and AC by Pythagorean Theorem:
AB:
[tex]AB = \sqrt{(12-0)^{2}+(3-8)^{2}}[/tex]
[tex]AB = 13[/tex]
BC:
[tex]BC = \sqrt{(7-12)^{2}+(-9-3)^{2}}[/tex]
[tex]BC = 13[/tex]
AC:
[tex]AC = \sqrt{(7-0)^{2}+(-9-8)^{2}}[/tex]
[tex]AC \approx 18.385[/tex]
Now, we can determine the area of the triangle ([tex]A[/tex]) by Heron's formula:
[tex]A = \sqrt{s\cdot (s-AB)\cdot (s-BC)\cdot (s-AC)}[/tex] (1)
[tex]s = \frac{AB+BC+AC}{2}[/tex] (2)
Where [tex]s[/tex] is the semiperimeter of the triangle.
If we know that [tex]AB = 13[/tex], [tex]BC = 13[/tex] and [tex]AC \approx 18.385[/tex], then the area of the triangle is:
[tex]s = 22.193[/tex]
[tex]A = 84.511[/tex]
The area of the triangle is 84.511 square units.

Bags of sugar come in 3 sizes:
Small bag: A 250 g bag costs 85p.
Medium bag: A 500 g bag costs £1.90.
Large bag: A 3 kg bag costs £3.90.
Calculate the cost of 3 kg for the small and medium bags.
Give your answer in pounds to 2 dp.
Write the bag that is the better value in the comments.
Answer:3kg of small bag costs £10.20 while 3kg of the medium bag costs £11.40. Hence, the bag with better value which is the cheapest is a 3kg of the big bag which costs £3.9

What is the 35th number in the sequence 4, 7, 12, 19, 28,…?
Answer:
n²+3. is the nth term
Step-by-step explanation:
can someone please help me?!
Answer:
x = 119
z = 28
Step-by-step explanation:
To find x: Because of same-side exterior angles, you can add x and 61 together to find 180 degrees.
x + 61 = 180
Subtraction: x = 119
To find z: Use given quantities, not found variables for most accurate answer. Because of opposite exterior angles, you can equal them to each other.
61 = 5z - 79
Addition: 140 = 5z
Division: 140/5 = 5z/5
Final Answer = 28 = z
