Answer:
x =4 and y =1
Step-by-step explanation:
Triangle ADB is an equilateral triangle that means the side a 3 unit each
so,
y + 2 = 3
y = 1
Triangle DBC is an isosceles triangle that means two legs are equal
So,
y + 2 = x -1
we already know that y+2 = 3
So,
3 = x -1
4 = x

A.
Answer: D. Pansy will take $25 per week from her account
Step-by-step explanation:
Based on the information given in the question, the true statement is that Pansy will take $25 per week from her account. This is represented by $25x.
For example, if the number of weeks that he used is 8 weeks. The amount in the savings account will be:
y = $25x + $500
y = $25(8) + $500
y = $200 + $500
y = $700

Answer:
x = y = 15[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{30}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2x = 30[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
x = 15[tex]\sqrt{2}[/tex]
The triangle is isosceles (45- 45- 90) , then 2 legs are congruent, so
y = x = 15[tex]\sqrt{2}[/tex]

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 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

Answer:
189.05 ft^3
Step-by-step explanation:
I think this is the right answer but I'm not 100% sure.
So first, you need to find the area of the rectangular prism. 5*5=25, and there are 5 of these rectangles (4 sides and the bottom), so the total is 125 ft^3. I don't think you would include the area of the top, as the top is not flat, and has a pyramid on it.
To find the area of the pyramid, there is a somewhat complicated and long equation that I can't write here, but you can look up the formula for the area of a square pyramid.
The area of the pyramid is around 64.05 ft^3. 125+64.05=189.0500 rounded to the nearest hundredth is 189.05 ft^3.

Answer:
A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape.
Step-by-step explanation:
A triangle having no side congruent is called is called Scalene triangle.
We have a triangle having no side congruent.
We have to identify the name of this triangle.
What is a Triangle ?A triangle is a plane figure with three straight sides and three angles.
According to question, we have -
A triangle with no side congruent. If all the three sides of a triangle are of same length then it is called congruent triangle. It is also called Equilateral triangle. Similarly, a triangle with none of its sides equal or congruent is called a Scalene triangle.
Hence, a triangle having no side congruent is called is called Scalene triangle.

Let's analyze the example first:
We have:
3, 4, 6 target 42 answer: (3 + 4)*6
If we solve the equation, we get:
(3 + 4)*6 = 7*6 = 42
So, we need to reorder the first 3 numbers in an expression, such that the solution of the expression is the target number.
a) 2, 5, 6 Target 40
We know that 5*8 = 40
and that 2 + 6 = 8
Then the answer is:
(2 + 6)*5
b) 3, 4, 6 target 12
Here we know that 4*3 = 12
and 6 - 3 = 3
Then the answer is:
(6 - 3)*4
c) 4, 6, 10 target 1.
We know that the quotient of two equal numbers is 1.
And 4 + 6 = 10
Then the answer here is:
(4 + 6)/10
d) 3, 5, 6 target 21
We know that 3*5 = 15
And 15 + 6 = 21
Then the answer here is:
3*5 + 6
e) 2, 7, 10 target 6.
Here is a harder one.
We know that 2*3 = 6
And that 10 - 7 = 3
Then the answer ere is:
2*(10 - 7)
f) 3, 6, 15 target 3
Here we can use:
(15 - 6) = 9
And 9/3 = 3
Then the answer is:
(15 - 6)/3

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.
