272 sweets are divided between Ram and Rahim in the ratio of 7 : 9. How many sweets do they get?
Answer:
let the ratio of ram and hari be 7x and 9x respectively
7x +9x=272
or, 16x=272
or,x=272÷16
or,x=17
ratio of ram=7x=7 × 17=119
ratio pf rahim=9x=9×17=153

Solve the system using any method: y = 3x + 4 6x2y=8
Answer:
y=24,x=20/3
[tex]y = 3x + 4[/tex]
[tex]8 = 6 \times 2y[/tex]
[tex] 2y = 8 \times 6 [/tex]
[tex]y = 24[/tex]
[tex]24 = 3x + 4[/tex]
[tex] - 3x = 4 - 24[/tex]
[tex] x = \frac{20}{3} [/tex]

1;3;5 are the first three terms of the first differences of a quadratic sequence. the 7 term of the quadratic sequence is 35. determine the 6th and 5th term of the quadratic sequence
Answer:
no
Step-by-step explanation:
The 6th and 5th terms of the giving sequence are respectively; 24 and 15
What are the missing terms of an Arithmetic Sequence?
We are given the first 3 terms of the sequence as; 1, 3 and 5.
We are told that the 7th term is 35.
Let xₙ be the nth term number in the quadratic sequence
dₙ is first difference number in the quadratic sequence
From the given sequence, we see that there is a common difference of 2 for the first 3 terms and so they follow an arithmetic sequence which is;
dₙ = 2n - 1
However, when we apply this up to the 7th term, that would not work. Thus, let us use the differences. We see that sum of two consecutive number position of terms is equal to the difference between the two consecutive terms.
Thus;
difference between 3rd and 4th term = 3 + 4 = 7
difference between 5th and 6th term = 4 + 5 = 9
difference between 6th and 7th term = 5 + 6 = 11
Thus, since 7th term is 35, then;
6th term = 35 - 11 = 24
5th term = 24 - 9 = 15

14 club members have birthdays in summer. This is 20% of the birthdays in the club. How many club members are there? How do you do this, for kids?
Answer:
70 club members in all
Step-by-step explanation:
we know that 14 people is equal to 20%
we also know that to get 20% to 100% you multiply by 5
So, what I did was mmultiply 14 by 5 therefore bringing 14 (20%) to 70 (100%)
hope this makes sense. for other values you could just see what to multiply the percent by to get to 100 and multiply the known number by that value.
hope this helps <3
Answer:
70 members
Step-by-step explanation:
Whatever the % is, the answer on the right side of the equation must by 14
So 20% of some number = 14.
20/100 x = 14 Remember 20% = 20 / 100. Multiply by 100
20x = 14*100
20x = 1400 Divide by 20
x = 1400/20
x = 70
There are 70 members in the club.
Kids are done no differently.
The number of people who fulfill the condition goes on the right. The left contains the % and an unknown.

Find the volume of the solid
Answer:
245 yd3
Step-by-step explanation:
Split the solid into two pieces, multiply length, width, adn height from there.
Answer:
The answer is: 245 yds cubed
Step-by-step explanation:
So first, you would cut the solid into 2 parts. One that is a big rectangular prism and the other is the smaller one. Next, we would solve the volume of the smaller rectangular prism. The measurements for that is:
Height: 2 Length: 5 Width: 2. There is a side of that small prism that is 2x2 so we will solve that first. 2*2=4. 4*5=20. The volume of the smaller rectangular prism is 20 yd^3.
Next, we solve the volume for the 2nd rectangular prism. The measurements for that are: Height: 5 Length: 9 Width: 5.
So we would first solve for one of the sides. 5*5=25. Then we would multiply it by 9. 25*9= 225. So the volume for the bigger rectangular prism is 225 yds^3.
Lastly, we will add the volumes of the two prisms together. 225+20=245.
The final answer is: 245 yds cubed
Find the equation of the straight line passing through the point (-4,5) and perpendicular to the line y=2x+7.Suppose the equation is y=cx+d.Find c,d.
Answer:
The equation of the line is:
[tex]y = -\frac{1}{2}x + 3[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept.
Perpendicular lines:
If two lines are perpendicular, this means that the multiplication of their slopes is -1.
Perpendicular to y=2x+7
This means that:
[tex]2m = -1[/tex]
[tex]m = -\frac{1}{2}[/tex]
So
[tex]y = -\frac{1}{2}x + b[/tex]
Passing through the point (-4,5)
This means that when [tex]x = -4, y = 5[/tex]. We use this to find b.
[tex]y = -\frac{1}{2}x + b[/tex]
[tex]5 = -\frac{1}{2}(-4) + b[/tex]
[tex]2 + b = 5[/tex]
[tex]b = 3[/tex]
The equation of the line is:
[tex]y = -\frac{1}{2}x + 3[/tex]
