The value of y in y = 5x if the value of x doubles itself is y also doubles itself; option A
How to solve equation?y = 5x
if x = 2
y = 5(2)
y = 10
if the value of x doubles, for instance, if x = 4
y = 5(4)
y = 20
y = 5/x
if x = 0.5
y = 5/0.5
y = 10
if the value of x triples, for instance, if x = 0.125
y = 5/x
= 5/0.125
y = 40
The value of y in y = 5/x if the value of x triples itself is y also triples itself; option B

Step-by-step explanation:
[tex](4)^2 =16[/tex]
[tex](4)^{-2} =\frac{1}{16}[/tex]
Hope it helps you in your learning process.
[tex]\large{\textsf{\textbf{Answer\::}}[/tex]
Option B
[tex]\large{\textsf{\textbf{Calculations\::}}[/tex]
If the base is 4 , and the exponent is 2 , then the expression looks as follows :
[tex]\textbf{\textsf{$4^2$}}[/tex]
So we multiply 4 times itself .
The answer is :
[tex]\textsf{\textbf{16}}[/tex]
Detail : 4² is not equal to 4×2 , and here's why .
4² = 4 × 4 = 16
4 × 2 = 8
Now , if the exponent is negative , then we turn the number over as follows :
4⁻² = [tex]\mathsf{\dfrac{1}{16} }[/tex]
So the right option is :
[tex]\bigcirc[/tex] 16 , -16
[tex]\bigcirc\!\!\!\!\!\!\bigstar[/tex] 16 , 1/16

A triangle has sides with lengths of 10 millimeters, 25 millimeters, and 28 millimeters, is it a right triangle
Answers
Answer:
No, it is not a right triangle.
Step-by-step explanation:
Let's take it as,
→ Hypotenuse = 28 mm
→ Perpendicular = 25 mm
→ Base = 10 mm
Now use Pythagoras theorem,
→ Hypotenuse² = Perpendicular² + Base²
→ 28² = 25² + 10²
→ 784 = 625 + 100
→ 784 ≠ 725
→ [ LHS ≠ RHS ]
Hence, it does not forms a right triangle.

Pema is 85 months old and Rinzin is 7⅔ years old. who is older? How do you know?
help me slove this please
Answers
Answer:
Rinzin is older
Step-by-step explanation:
The reason is that since you probably already know that there are 12 months in a year it would be 85/12=7.0833 years and 23/12=7.666 so that makes rinzin older
Hope that helps :)
Pema is older than Rinzin if Pema is 85 months old and Rinzin is 7⅔ years old.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Pema is 85 months old and
Rinzin is 7⅔ years old.
We have to check who is older.
We know that 1 year = 12 months
So if 85 months are conveted to years by dividing 85 by 12
Pema, 85/12 years= 7.08 years
Rinzin, 7⅔ years = 7.06 years
We know that 7.08>7.06
Hence, Pema is older than Rinzin if Pema is 85 months old and Rinzin is 7⅔ years old.

What is the slope of the line?

Answers
Answer:
The slope is [tex]-\frac{4}{3}[/tex]
Step-by-step explanation:
Standard form for a linear equation/graph:
[tex]y = mx + b[/tex]
[tex]m[/tex] is the slope, and [tex]b\\[/tex] is the Y- intercept (basically where the graph crosses the y axis).
[tex]m[/tex] can be shown by a fraction: [tex]\frac{Rise}{Run}[/tex]
In this graph, measuring from the two points of contact, the rise is 4 and the run is -3. If the graph moves towards the left while rising, then the run part of the slope should be negative, and vice versa.
Thus, the slope of this graph is [tex]-\frac{4}{3}[/tex]
Here's the function for the line if you need it:

Kathleen says that all quadrilaterals have right angles. Grace says that quadrilaterals do not have to have right angles. Explain who is correct.
Answers
Answer: Grace is correct because a rhombus does not have right angles
Step-by-step explanation:
Grace's assertion is on point. Right angles are not present in all quadrilaterals.
What is quadrilateral?A quadrilateral in geometry is a four-sided polygon with four edges and four corners.
As per the definition of Quadrilateral and rectangle, the rectangle is the type of quadrilateral that has 4 right angles.
Other varieties of quadrilaterals consist of:
Trapezium: Doesn't must have four right angles, but has one pair of opposite sides that are parallel.
A parallelogram has four right angles, but not necessarily two sets of opposite sides that are parallel.
All four sides of a rhombus are equal in length, although there aren't always four right angles.
Kite: Does not must have four right angles, but two adjacent pairs of sides that are equal in length.
Therefore, Grace's assertion is right.

C. 0.165
D. 0.275
Answers
Answer: C. 0.165
Step-by-step explanation:
The value of P(A∪B) = 0.835
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given that, A and B are dependent events. If P(AIB) = 0.55 and P(B) = 0.3,
0.55 = P(A∩B) / 0.3
P(A∩B) = 0.165
P(A) = 1-P(B)
P(A) = 1-0.3
P(A) - 0.7
P(A∪B) = P(A) + P(B) - P(A∩B)
P(A∪B) = 0.3+0.7-0.165
P(A∪B) = 0.835
Hence, the value of P(A∪B) = 0.835
