The number of boys attended are 49.
What is the definition of the ratio?In mathematics, a ratio is a term used to compare two numbers. It is used to express how large or small an amount is in comparison to another. A ratio compares two quantities by dividing them. The dividend is referred to as the 'antecedent,' while the divisor is referred to as the 'consequent.'For the given question.
Let the number of girls be 'x' = 63.
Let the number of boys be 'y'.
The ratio of girls to boy is 9:7.
Thus,
x/y = 9/7
Boys = ?
y = 7x/9
Put x = 63
y = 7×63/9
y = 49
Thus, the number of boys attended are 49.

Marcus is building a fence around his rectangular backyard. The length of his backyard is
75
3/4
ft, and the width is
81
1/4
ft. If the fence is
3/4
finished, how much fencing is left to complete?
Answer:
4,923.75ft²
Step-by-step explanation:
The area of the backyard = Length * width \
Area of the backyard = 75 3/4 * 81 1/4
Area of the backyard = 303/4 * 325/4
Area of the backyard = 6,154.6875ft²
If 3/4 of the fence is finished, the area of the finished part is expressed as;
Finished part = 1/5 * 6,154.6875
Finished part = 1,230.9375ft²
Part left unfinished = 6,154.6875-1,230.9375
Part left unfinished = 4,923.75ft²

If y = -5, what is the value of
2y+2
-
4
Answer:
-12
Step-by-step explanation:
Ok so I'm guessing that's a -4 but if its not, please correct me.
y= -5 is going to be plugged into 2y+2-4
This means that 2(-5)+2-4=?
2(-5) is the equivalent to 2 times -5, which is -10 (you solve multiplication first because order of operations)
Now, 2-4=-2
So using this, let's combine both equations!
-10+-2=?
?=-12

y - 7/8 = 3/4
what is y
;-;
Answer:
y = 13/8
Step-by-step explanation:
Here are the steps I did:
1. y - 7/8 = 3/4 x 2/2
2. y - 7/8 + 7/8 = 6/8 + 7/8
3. y = 13/8
Answer:
Y in (-oo:+oo) Y- (7/8) = 3/4 // - 3/4. Y- (7/8)- (3/4) = 0. Y-7/8-3/4 = 0. Y-13/8 = 0 // + 13/8. Y = 13/8. Y = 13/8.

Josh is 6 years older than 4 times Kim's age. the sum of their ages is less than 31.
what is the oldest Kim could be?
Answer:
4
Step-by-step explanation:
31 - 6 = 25
25/4 = 5
because its LESS than that, it has to be lower than 5, therefore its 4.
Kim should be 12 years old.
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Josh is 6 years older than 4 times Kim's age and the sum of their ages is less than 31.
From the information, let's consider Josh's age be J and that age Kim's be K
As given,
J = 6 + K ..............(i)
And,
J+K < 31
Substituting in eq(i)
6+K+K < 31
2K < 25
K < 25/2
K < 12.5
Since, Kim's age should be less than 12.5
Hence, Kim's age is 12 years.

He highest priced diamond ever sold at auction weighed 69.42 carats and sold for $1,050,000. A carat is equal to 0.2 grams. What was the weight of this diamond in grams?
Answer:
13.884 grams
Step-by-step explanation:
From the question:
1 carat = 0.2 grams
The highest priced diamond = 69.42 carats.
Hence:
1 carat = 0.2 grams
69.42 carats = x grams
x grams = 69.42 × 0.2 grams
x grams = 13.884 grams
Hence, the weight of the highest priced diamonds is 13.884 grams.
In triangle QRS, the measure of
angle Q is 70º. Angle R is
congruent to angle S. What is the
measure of angle R in degrees?
Answer:
55 degrees :)
Step-by-step explanation:
all triangles add up to 180 degrees.
we already have 70 degrees and since <S = <R they are the same # of degrees.
subtract 70 from 180 and we get 110.
divide 110 by 2=55
<S 55
<R 55
<Q 70

9. Stephanie had some candy to give to her four children. She first
took twelve pieces for herself and then evenly divided the rest among
her children. Each child received six pieces. With how many pieces did
she start?
Answer:
36
Step-by-step explanation:
Create an equation : 12 for how many pieces Stephanie took, 4 for how many children she has and 6 for how many pieces each child got:
12+ (6*4) = x
Solve:
12+24 = 36
Answer: 36 pieces
Step-by-step explanation:
We know she took 12 pieces and her four children each received 6 pieces.
12 + 4 (6) = p
12 + 24 = 36
p = 36
She started with 36 pieces.

how do you graph 24x−6y=18
Answer:
You will graph a function with the equation being y = 4x - 3, to plot this function read step by step explanation.
Step-by-step explanation:
First we have to find the equation of the line so we do....
24x - 6y = 18
24x = 18 + 6y
6y = 24x - 18
y = 4x - 3
Now that we know the equation we just have to find two point by using this equation and connect them between each other in order to graph the function represented by this equation. For example
For x = 0
y = 4x - 3
y = -3
So we know that there is a point (0, - 3)
For x = 1
y = 4x - 3
y = 4 - 3
y = 1
So we know that there is a a point (1, 1)
Connect the two point and you will get the function graph

the difference of 2x and 15 is less than or equal to the sum of 4x and 17
Step-by-step explanation:
the difference of 2x and 15 is less than or equal to the
sum of 4x and 17
i.e.,
2x - 15 < 4x + 17
if you want to find ahead then
2x - 15 = 4x + 17
2x - 4x = 17 + 15
- 2x = 32
x = - 32/2
x = - 2
(h(1) h(1) = 0 h(n) = h(n-1) - 9 Find an explicit formula for h(n).
Answer:
h(n)=0−9(n−1)
Step-by-step explanation:
From the recursive formula, we can tell that the first term of the sequence is 0
and the common difference is -9
This is the explicit formula of the sequence:
h(n)=0−9(n−1)
Note that this solution strategy results in this formula, however, an equally correct solution can be written in other equivalent forms as well.
