A tailor needs to make uniforms for 32 students from a piece of cloth. If the length of that piece 45 3/4m and each student requires 1 1/8m, calculate the length of cloth that would be left
Answer:
uniform for 1 student = 1 1/8 = 9/8
uniform 32 students = 32 x 9/8 = 36m
Total cloth = 45 3/4 = 183/4 = 45.75m
Cloth left = 45.75 - 36 = 9.75m i hope that helps

Find the vertices of the hyperbola. Enter the smallest coordinate first.
Answer:
([-3], [0]), ([3], [0])
Step-by-step explanation:
The given equation of the hyperbola is presented as follows;
[tex]\dfrac{x^2}{9} - \dfrac{y^2}{49} = 1[/tex]
The vertices of an hyperbola (of the form) [tex]\dfrac{x^2}{a^2} - \dfrac{y^2}{b^2} = 1[/tex] are (± a, 0)
The given hyperbola can we presented in a similar form as follows;
[tex]\dfrac{x^2}{9} - \dfrac{y^2}{49} = \dfrac{x^2}{3^2} - \dfrac{y^2}{7^2} = 1[/tex]
Therefore, by comparison, the vertices of the parabola are (± 3, 0), which gives;
The vertices of the parabola are ([-3], [0]), ([3], [0]).

Answer:
The parallelogram ABCD is what makes the parallelogram.
The proof given was AC and BD bisect each other.
Bisect means to divide into 2 parts. AC and BD both divide into 2 parts with each other.
But the lines need to be in 2 equal parts.
So if we were to divide it in that case, it would be able to bisect.
This is given proof that parallelogram ABCD is a parallelogram.
Answer:
Solution given:
ABCD is a parallegram.
In ∆ADE and ∆BCE
AD=BC[corresponding side of parallelogram are equal]
<AED=<BEC[ vertically opposite angle]
<ADE=<EBC[alternate angle]
so
∆ADE are congruent to ∆BCE by S.A.A. axiom
we have
DE=BE[corresponding side of congruent triangle are equal]
Similarly
AE=CE
we have
AC=BD
AE+CE=BE+DE
2AE=2BE
AE=BE
so.we can rightly say that AC and BD bisect each other.

Why is 6/5 not equivalent to 3/2
Answer:
It is the first choiceStep-by-step explanation:
[tex] \frac{3 \times 2}{2 \times 2} = \frac{6}{4} \\ \\ \frac{6}{4} \: \: is \: not \: equal \: to \: \: \: \: \frac{6}{5} [/tex]
The ratio 3 / 2 is multiplied by 2 on both the denominator and numerator to get the value 6 / 4, but the denominator part is not equal to 5, hence 6/5 is not equivalent to 3/2, so option A is correct.
What is the ratio?It is the comparison of one quantity with another. For example, if your weight is 30 kg and your father's weight is 90 kg, then the ratio of weight is 1:3.
Given:
6 / 5 and 3 / 2
As you can see the numerator of 3 / 2 is multiplied by 2 to get the value 6, so the denomination should also be multiplied by the number 2,
(3 × 2 ) / (2 × 2)
6 / 4
But the result came as 4 on the numerator,
Thus, 6 / 5 and 3 / 2 are not equivalent.

Answer:
7.) x = 12
9.) x = 4
Step-by-step explanation:
7.) Angle Y and Angle X both add up to 180
=> 40 + 12x - 4 = 180
=> 36 + 12x = 180
=> 12x = 180 - 36
=> 12x = 144
=> x = 12
9.) Angle W and Angle X add up to 180
=> 145 + (-1) + 9x = 180
=> 144 + 9x = 180
=> 9x = 180 - 144
=> 9x = 36
=> x = 36 / 9
=> x = 4
Hope this helps!

Answer:
16 units
Step-by-step explanation:
For a right triangle, a²+b²=c², where a and b are leg lengths, and c is the hypotenuse. Given one leg length and the hypotenuse, we can find the other leg length by plugging in our given information:
a²+b²=c²
12²+b²=20²
144+b²=400
b²=256
b=16
Therefore, the missing leg length is 16 units.
G(x)=3/x find g'(x) a) by using the quotient rule: b) by first rewriting the expression using exponents and then differentiating.
Answer:
a) The quotient rule is:
if: f(x) = 1/g(x)
Then:
[tex]f'(x) = -\frac{1}{(g(x))^2}*g'(x)[/tex]
In this case, we have:
G(x) = 1/x
Then we can write this as:
G(x) = 1/h(x) with h(x) = x, and h'(x) = 1
Using the above rule we get:
G'(x) = -(1/h(x)^2)*h'(x) = -1/x^2
b) For a function like:
f(x) = x^n
we have that:
[tex]f'(x) = n*x^{n - 1}[/tex]
Here we can write G(x) = x^-1
Then we have n = -1
If we use the above rule, we get:
[tex]G'(x) = (-1)*x^{-1-1} = -1*x^{-2} = \frac{-1}{x^2}[/tex]
So we got the same result using both methods.
A shelf is built on a wall, as shown below. What is the value of x?
Answer:
X=25
Step-by-step explanation:
All angles of a triangle add up for 180
We know that there is a 90 degree right angle.
So (x+25)+(2x-10)=180-90
Remove parenthesis since they don't matter in this problem.
x+25+2x-10=90
Combine similar terms
3x+15=90
Subtract 15 from both sides
3x=75
Divide both sides by 3
x=25
