Answer: 35:46
Step-by-step explanation:
When 140 is divided in the ratio 4:3, the two parts are 80 and 60, respectively.
To divide 140 in the ratio 4:3, we need to split the value 140 into two parts such that the ratio of the two parts is 4:3.
The ratio 4:3 consists of two parts (4 parts and 3 parts), making a total of 7 parts.
4+3=7
Divide 140 into 7 equal parts:
To find the value of one part, we divide 140 by 7:
140 ÷ 7
= 20
Calculate the two parts using the ratio:
Now, we can find the value of the two parts based on the ratio.
4 parts = 4 × 20 = 80
3 parts = 3 × 20 = 60
Hence, when 140 is divided in the ratio 4:3, the two parts are 80 and 60, respectively.

Damarcus and Xavier went to the arcade to play their two favorite games. Damarcus played 4 rounds of game 1 and 6 rounds of game 2 for $18.00. Xavier played 5 rounds of each game for $20. What is the cost of game 1?
Answer:
$3
Step-by-step explanation:
Given :
Let game 1 = x ; game 2 = y
4x + 6y = 18 - - - (1)
5x + 5y = 20 - - - (2)
From (2)
x + y = 4
y = 4 - x
Substitute y = 4-x in (1)
4x + 6(4 - x) = 18
4x + 24 - 6x = 18
-2x = 18 - 24
-2x = - 6
x = 6/2
x = 3
Game 1 cost $3
Answer:

A monkey is swinging from a tree. On each swing she travels along an arc that is 75% as long as the previous swing arc. The total length of the arcs from her first 4 swings is 175m.
Answer:
The first swing is 64m
Step-by-step explanation:
The complete question asks for how long the first swing is.
The monkey is swinging from the tree with each swing being along an arc, where each arc is 75% of the previous arc. Also, given that its first four swings is 175cm, we can denote her first swing as y.
This means the second swing would be = 0.75y
The third would be = 0.75(0.75y) = 0.5625y
The fourth would be = 0.75(0.5625y) = 0.421875y
Since the total is 175, we have
y + 0.75y + 0.5625y + 0.421875y = 175
2.734375y = 175
y = 175/2.734375
y = 64m

A chess tournament was being held. This single-elimination tournament (in which paired competitors
played matches and only the winner of a match continued to the next round) began with 16 competitors.
How many matches were played?
A total of matches were played. _____
I really need help with this problem!
Answer:
A total of 15 matches were played.
Step-by-step explanation:
To determine the number of matches that were played in the chess tournament, knowing that there are 16 participants who face each other in a tournament of direct elimination, the following logical reasoning must be carried out:
In the first round there are 16 players, so being matches between 2 players, there are 8 matches (16/2). In the second round, applying the same reasoning and taking into account that there are only 8 players left, since the others have been eliminated, there are 4 matches (8/2). The same in the semifinals, where there are 2 games (4/2), and finally, the final to a single game.
Therefore, since 8 + 4 + 2 + 1 equals 15, the number of matches played in the tournament is 15.
A spinner has eight equal sections numbered from 1–8. Predict how many times the pointer will land on a 2 or a 5 if you spin the spinner 60 times.
Answer:
15 times
Step-by-step explanation:
By spinning once, the probability of landing on 2 is 1/8
The probability of landing on 5 is 1/8
The probability of landing on 2 or 5 is 1/8 + 1/8 = 2/8 = 1/4
So spinning 60 times, the number of times we expect a landing on 2 or 5 will be ;
1/4 * 60 = 15 times

The last time it placed an order for ingredients, Sweet Treats Bakery ordered 7,720 kilograms of sugar. This time, the bakery is ordering 13,510 kilograms. What is the percent of increase in the size of the sugar order?
Answer:
The percent of increase in the size of the sugar order is 75%.
Step-by-step explanation:
To find the percent of increase in the size of the sugar order, you can use the following formula:
% increase = ((New number-Original number) ÷ Original Number)x100
New number=13,510
Original number=7,720
Now, you can replace the values in the formula:
% increase = ((13,510-7,720) ÷ 7,720)x100
% increase = (5,790 ÷ 7,720)x100
% increase = 0.75x100
% increase = 75%
According to this, the answer is that the percent of increase in the size of the sugar order is 75%.
Answer:
i think 75%

the expression (x^-8) (x^3) is equivalent to the expression x^n. what is the value of n?
Answer:
n=-5
Step-by-step explanation:
You must multiply [tex]x^{-8}*x^{3}[/tex]. The laws of exponents state that when multiplying exponents of the same base, you can just add the exponents and raise the base to the sum of the exponents. So, [tex]x^{-8}*x^{3}=x^{(-8+3)}=x^{-5}[/tex]. Since our end product is [tex]x^{-5}[/tex], n is equal to -5.

cos sec² a - cot²a=1
Answer:
We want to prove the relation:
cosec(a)^2 - cot(a)^2 = 1
where:
cosec(a) = 1/sin(a)
cot(a) = 1/tg(a) = cos(a)/sin(a)
We can start with the relationship:
cos(a)^2 + sin(a)^2 = 1
Now, let's divide by sin(a)^2 in both sides:
(cos(a)^2 + sin(a)^2)/sin(a)^2 = 1/sin(a)^2
cos(a)^2/sin(a)^2 + sin(a)^2/sin(a)^2 = (1/sin(a))^2
(cos(a)/sin(a))^2 + 1 = (1/sin(a))^2
and remember that:
cosec(a) = 1/sin(a)
cot(a) = 1/tg(a) = cos(a)/sin(a)
Then we can write:
(cos(a)/sin(a))^2 + 1 = (1/sin(a))^2
as:
cot(a)^2 + 1 = cosec(a)^2
1 = cosec(a)^2 - cot(a)^2
And this is the relation we wanted to prove.

If angles of a triangle are in the ratio 2 : 3 : 4. Find the value of the largest angle.
(a) 120°
(b) 140°
(c) 60°
(d) 80°
Answer:
(d)
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 + 4 = 9 parts
Divide 180° by 9 to find the value of one part of the ratio
180° ÷ 9 = 20° ← value of 1 part of ratio , then
4 parts = 4 × 20° = 80° ← largest angle
Suzy is using a bucket to collect nuts from a nut tree. She then dumps the bucket into a barrel for shipping of the nuts. She notices that 1 over 2 the bucket of nuts fills 2 over 3 of the barrel.
Part A: Write and solve an equation to find the number of nuts that will fill the entire barrel. Show your work. (8 points)
Part B: Explain your answer in words. (2 points)
Answer:
3/4 bucket
Step-by-step explanation:
Given that:
1/2 bucket of nut fills 2/3 of barrel ;
Letbthe number of bucket if nut which fills entire barrel = x
Fraction of entire barrel = 1 /1 = 1
1/2 bucket = 2/3 barrel
x buckets = 1 barrel
Cross multiply ;
(2/3)x = 1/2
2x / 3 = 1/2
2x * 2 = 3 * 1
4x = 3
x = 3/4
Hence, 3/4 bucket of nut will fill entire barrel
