Answer:
Rob made 31, and Matt made 24
Step-by-step explanation:
55 in total
Rob made 7 more do 55 - 7 = 48
48 / 2 = 24
24 for Matt
24 +7 = 31
31 for rob
Answer:
24 cups of lemonade

Rob made 7 more then Matt. You could say that Matt made 24 and Rob made 31 and it would be correct.
Determine the value of z
Answer:
C
Step-by-step explanation:
First we need to find out y.
5y + 45 = 180 (angles on straight line)
y = 27
5y = 135
Then we could apply the angle sum of a pentagon to find out z.
90 + 5y + z + 82 + 135 = 180(5-2)
442 + z = 540
z = 98 i.e. C

There were 96 students and 34 adults at the concert. If 65% of the seats were filled, how many seats are in the auditoriom? Round your answer to the nearest whole percent
Answer: 200 seats
Step-by-step explanation:
There are 96 students and 34 adults in a concert. The total number of people present is therefore:
= 96 + 34
= 130 people
These 130 people only fill 65% of the seats. Assume the total number of seats is x:
130 = 65% * x
x = 130/65%
x = 200 seats

Miguel needs to fix a window screen that is 23 feet above the ground. A ladder leans against a building and forms a 75 degree angle with the ground. The angle where the building and ground meet is 90 degrees. The ladder he uses makes a 75° angle with the ground. What is the shortest possible length of the ladder if the top of it is 23 feet off the ground? Round to the nearest whole number. 6 ft 22 ft 24 ft 89 ft
Answer:
24
Step-by-step explanation:
i did it on edge
The shortest possible length of the ladder if the top of it is 23 feet off the ground is 24 ft.
What is right triangle?"It is a triangle in which one of the angle measures 90° "
What is hypotenuse?"It is the longest side in the right triangle."
What is Pythagoras theorem?"In right triangle, a² + b² = c², where c is hypotenuse and a, b are other two sides of the right triangle."
What is sine of angle?"In right triangle for angle x, [tex]sin(x)=\frac{opposite~ side~ of~ angle~x}{hypotenuse}[/tex] "
For given question,
Consider the following figure.
In right triangle WXY, WX is 23 feet as a window screen is 23 feet above the ground.
WY represents the ladder.
that is the hypotenuse of right triangle WXY is the length of the ladder.
A ladder leans against a building and forms a 75 degree angle with the ground
⇒ ∠WYX = 75°
Consider the sine of ∠WYX .
[tex]\Rightarrow sin(75)=\frac{WX}{WY}\\\\ \Rightarrow 0.9659=\frac{23}{WY}\\\\ \Rightarrow WY=\frac{23}{0.9659}\\\\ \Rightarrow WY=23.81\\\\\Rightarrow WY\approx 24[/tex]
This means the hypotenuse WY is approximately 24 ft.
Therefore, the shortest possible length of the ladder if the top of it is 23 feet off the ground is 24 ft.

Misha and Carlos collect baseball cards. Misha has been collecting cards longer and finds a ratio of 9 to 4 when comparing her total cards to her friend. If Carlos has 76 cards, how many cards do they have together?
Answer:
247 cards
Step-by-step explanation:
Misha : Carlos = 9 : 4
Carlos = 76 cards
Misha = x cards
9 : 4 = x : 76
9/4 = x/76
Cross product
9 * 76 = 4 * x
684 = 4x
x = 684 /4
x = 171
Misha = 171 cards
how many cards do they have together?
Total cards altogether = Misha + Carlos
= 171 cards + 76 cards
= 247 cards
Total cards altogether = 247 cards

what is the square root of 2.4 divided by the reciprocal of 3 , divided by 0.483?
My answer is 1.192 I hope this helps u
Answer:
9.622318872565011
Step-by-step explanation:
The square root of 2.4 is a very long decimal, but here it is: 1.549193338482967
And if you divide it by the reciprocal of 3, (which is 1/3) it would basically be multiplying by 3. So:
1.549193338482967 x 3= 4.6475800154489
Finally, divide it by 0.483:
9.622318872565011

Prove the sum of three consecutive is divisible by three, that the sum of 5 consecutive integers is divisible by 5, but the sum of four consecutive integers is not divisible by 4
Answer:
Proved
Step-by-step explanation:
Solving (a):
Let the numbers be: [tex]x, x + 1, x + 2.[/tex]
Their sum is:
[tex]Sum = x + x + 1 + x + 2[/tex]
Collect Like Terms
[tex]Sum = x + x + x + 1 + 2[/tex]
[tex]Sum = 3x + 3[/tex]
Divide sum by 3.
[tex]Result = \frac{Sum}{3}[/tex]
[tex]Result = \frac{3x+3}{3}[/tex]
[tex]Result = \frac{3(x+1)}{3}[/tex]
[tex]Result = x + 1[/tex]
Hence, this is true because there is no fractional part after the division
Solving (b):
Let the numbers be: [tex]x, x + 1, x + 2,x+3,x+4[/tex]
Their sum is:
[tex]Sum = x + x + 1 + x + 2+x + 3 + x + 4[/tex]
Collect Like Terms
[tex]Sum = x + x + x + x + x+1 + 2 + 3 + 4[/tex]
[tex]Sum = 5x+10[/tex]
Divide sum by 5.
[tex]Result = \frac{5x + 10}{5}[/tex]
[tex]Result = \frac{5(x + 2)}{5}[/tex]
[tex]Result = x + 2[/tex]
Hence, this is true because there is no fractional part after the division
Solving (c):
Let the numbers be: [tex]x, x + 1, x + 2,x+3[/tex]
Their sum is:
[tex]Sum = x + x + 1 + x + 2+x + 3[/tex]
Collect Like Terms
[tex]Sum = x + x + x + x + 1 + 2 + 3[/tex]
[tex]Sum = 4x+6[/tex]
Divide sum by 4.
[tex]Result = \frac{4x + 6}{4}[/tex]
Split
[tex]Result = \frac{4x}{4} + \frac{6}{4}[/tex]
[tex]Result = x + 1.5[/tex]
The 1.5 means that the sum can not be divisible by 4
On Wednesday, 9 out of every 11 students attended tutoring. If 55 students were assigned tutoring, how many students did not attend tutoring
Answer:
10 students
Step-by-step explanation:
Hi there!
To find the answer, we first know that 9/11 students attend tutoring.
If 55 are assigned, that means that 45/55 students showed up.
This is because 11 * 5 = 55, which means this can be solved fairly easily now.
Since we multiplied the denominator, 11, by 5, we have to do the same thing to 9.
9 * 5 = 45
Now we have 45/55. We know that 45 students out of the 55 that were assigned showed up, but its asking for how many did not show up, so we just subtract 45 from 55 to get 10.
10 students did not show up for tutoring.

Ali is y years old.
Bhavara is twice as old as Ali.
Ceris is 3 years younger than Ali.
The total of their ages is 125
years.
Work out the age of each person.
(4 marks)
Ali years=
Bhavara years=
Ceris years=
Ali = Y
Bha = 2Y
Cer = Y - 3
Then
Y + 2Y + Y-3 = 125
4Y - 3 = 125
4Y = 128
Ali = Y = 32
Bha = 2Y = 64
Cer = Y - 3 = 29
Hope it Helps :)
The ages of each person are,
⇒ Ali years = 32
⇒ Bhavana years = 64
⇒ Ceris years = 29
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Ali is y years old.
Bhavara is twice as old as Ali.
Ceris is 3 years younger than Ali.
And, The total of their ages is 125 years.
Now,
Since, The age of Ali = y
And, Bhavara is twice as old as Ali.
Hence, The age of Bhavara = 2y
And, Ceris is 3 years younger than Ali.
Hence, The age of Ceris = y - 3
Here, The total of their ages is 125 years.
Hence, We get;
⇒ y + 2y + y - 3 = 125
⇒ 4y - 3 = 125
⇒ 4y = 125 + 3
⇒ 4y = 128
⇒ y = 32
Thus, We get;
The age of Ali = 32 years
The age of Bhavara = 2y
= 2 × 32
= 64 years
The age of Ceris = y - 3
= 32 - 3
= 29 years
