a) In the given figure, ABC – XCY, BC = 9 cm,
BY = 3 cm and XY = 4 cm.
Find the length of AB.
Answers
Answer:
AB = 12 cm
Step-by-step explanation:
AB/BC = XY/BY
From the above question:
AB = ??
BC = 9cm
XY = 4cm
BY = 3 cm
AB/9 = 4/3
Cross Multiply
AB × 3 = 9 × 4
AB = 9 × 4/3
AB = 12 cm
Therefore, Length AB = 12cm

Solve the system by substitution.
y=X - 8
y = 2x – 14.
Answers
Hey there!
The answer to your question is (6, -2)
To solve for substitution, we simply make the right side of the equations equal to each other:
[tex]x-8=2x-14[/tex]
Add [tex]14[/tex] to both sides:
[tex]x + 6 = 2x[/tex]
Subtract [tex]x[/tex] from both sides
[tex]6=x[/tex]
Now, we have to solve for [tex]y[/tex], and we can do so by plugging in the value of [tex]x[/tex] in to one of the equations:
[tex]y = 6 - 8[/tex]
[tex]y = -2[/tex]
Therefore, your solution is (6, -2)
Have a terrificly amazing day!
On a snow day, Hunter created two snowmen in his backyard. Snowman A
was built to a height of 35 inches and Snowman B was built to a height of 50
inches. The next day, the temperature increased and both snowmen began to
melt. At sunrise, Snowman A's height decrease by 4 inches per hour and
Snowman B's height decreased by 7 inches per hour. Let A represent the
height of Snowman At hours after sunrise and let B represent the height of
Snowman B t hours after sunrise. Write an equation for each situation, in
terms of t, and determine how tall each snowman is when they are the same
height.
Answers
Answer:
A = 35 - 4t
B = 50 - 7t
Height = 15 inches
Step-by-step explanation:
Given that:
Height of snowman A = 35 inches
Height of snowman B = 50 inches
Height decrease of snowman A = 4 inches per hour
Height decrease of snowman B = 7 inches per hour
t = number of hours
A = 35 - 4t Eqn 1
B = 50 - 7t Eqn 2
At same height,
Eqn 1 = Eqn 2
35 - 4t = 50 - 7t
-4t + 7t = 50 - 35
3t = 15
Dividing both sides by 3
[tex]\frac{3t}{3}=\frac{15}{3}\\t=5[/tex]
Putting t=5 in both equations
A = 35 - 4(5) = 35 - 20 = 15 inches
B = 50 - 7(5) = 50 - 35 = 15 inches
Hence,
A = 35 - 4t
B = 50 - 7t
Height = 15 inches
The equation should be
A = 35 - 4t
B = 50 - 7t
And, the Height = 15 inches
Calculation of the equation and height;
Since
Height of snowman A = 35 inches
Height of snowman B = 50 inches
Height decrease of snowman A = 4 inches per hour
Height decrease of snowman B = 7 inches per hour
Here, t = number of hours
So, the equation should be
A = 35 - 4t
B = 50 - 7t
Now for the same height
35 - 4t = 50 - 7t
-4t + 7t = 50 - 35
3t = 15
t = 15
So,
A = 35 - 4(5) = 35 - 20 = 15 inches
B = 50 - 7(5) = 50 - 35 = 15 inches

Answers
9514 1404 393
Answer:
(a) 84°
Step-by-step explanation:
If the upper side of angle 1 is extended so that it crosses the lower parallel, the angle it makes there corresponds to the one marked 51°, so is also 51°. That makes angle 1 the exterior angle of a triangle with remote interior angles of 51° and 33°. Angle 1 is the sum of those angles:
∠1 = 51° +33° = 84°
_____
Alternate solution
Draw a line through the vertex of angle 1 parallel to the other two parallel lines. The lower half of angle 1 is then an alternate interior angle to the one marked 33°, so is 33°. The upper half of angle 1 is a corresponding angle to the one marked 51°, so is 51°. That makes angle 1 be the sum of 33° and 51° angles, so 84°.
graph this please it’s been due
Answers
Answer:
Step-by-step explanation:
Here, we want to graph the given line
To do this, we need the x and y intercept
The general equation form
is ;
y = mx + b
where m is slope and b is the y-intercept
from the question, b is -2
The point at b is (0,-2)
To get the x-intercept, equate y to 0
0 = 3x - 2
3x = 2
x = 2/3
So the x-intercept is (2/3,0)
So to graph the line, we have to join the points;
(0,-2) and (2/3,0) with a straight line

A jar contains 15 red marbles, 10 green marbles, and 11 blue marbles. What is the probability that a marble chosen at random from the jar will NOT be green?
Answers
Answer:
Quantity A is greater.
Step-by-step explanation:
Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue. The probabilities of each of these events, added together would be (2/16) * (14/15) + (14/16) * (2/15) = 0.2333333333; therefore, A is more probable.

Answers
Answer:
5/10
Step-by-step explanation:
if you add all the non- chocolate chip cookies than you have 10 other cookies.
since there are 5 chocolate chip cookies than the probability would be
5/10 or 1/2
The probability of picking a chocolate chip cookie is 1/3.
Given that, a box contains 5 chocolate chip cookies, 4 sugar and 6 oatmeal raisin.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Here,
Total number of outcomes =15
Number of favorable outcomes = 5
Probability of an event = 5/15
= 1/3
Therefore, the probability of picking a chocolate chip cookie is 1/3.

Thus, f and g are inverse functions
Step-by-step explanation:
Inverse Functions
If two functions f(x) and g(x) are inverses, then it follows that:
[tex]f\circ g(x)=x[/tex]
Or:
[tex]g\circ f(x)=x[/tex]
We are given
[tex]\displaystyle f(x)=\frac{1}{4}x-6[/tex]
[tex]g(x)=4x+24[/tex]
Let's test if they are inverse functions:
[tex]f\circ g(x)=\frac{1}{4}(4x+24)-6[/tex]
Simplifying:
[tex]f\circ g(x)=x+6-6=x[/tex]
Now find:
[tex]\displaystyle g\circ f(x)=4\left(\frac{1}{4}x-6\right)+24[/tex]
Operating:
[tex]\displaystyle g\circ f(x)=x-24+24=x[/tex]
Thus, f and g are inverse functions

What is the area, in square feet, of the shape below? Express your answer as a fraction in simplest form.
Answers
The area of the triangle will be 5/8 square feet.
What is triangle?
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted ΔABC.
In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Area: ½ × base × heightPerimeter: sum of side lengths of the triangleNumber of vertices: 3Number of edges: 3Internal angle: 60° (for equilateral)Sum of interior angles: 180°Right angle: 90 degreesGiven is a triangle as shown in the image.
Now, the area of triangle will can be written as -
[A] = 1/2 x [b] x [h]
[A] = 1/2 x 5/3 x 3/4
[A] = 1/2 x 5/4
[A] = 5/8 square feet
Therefore, the area of the triangle will be 5/8 square feet.
