the area of this square = ___ cm
Answer:
64cm² I think :) if u get it wrong dont blame it on me.
Answer:
64 cm^2
Step-by-step explanation:
The area of a square can be calculated by A = s^2 (Area = side squared aka the side multiplied by itself)
A = s^2
= 8^2 (8 x 8)
= 64 cm^2
For triangle ABC C = 90 Side AC = 13.5 Side BC = 8.6 Find the measure of angle B
Answer:
57.5°
Step-by-step explanation:
For triangle ABC C = 90 Side AC = 13.5 Side BC = 8.6 Find the measure of angle B
We solve using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle B
Opposite = Side AC 13.5
Adjacent = Side BC = 8.6
Hence:
tan θ = 13.5/8.6
θ = arc tan (13.5/8.6)
θ = 57.501354056°
Approximately = 57.5°
Therefore, Angle B = 57.5°

How to find the graph of an equation using slope and y-intercept?Slope and y-intercept are used to graph an equation in the following ways:
The equation y = mx + b's y-intercept is equal to b.Draw a y-intercept plot. The key message is (0, b).To solve the equation y = mx + b, get the slope=m.Rise above from (0,b) by m units and to the right by 1 unit.With your line, join those two spots together.How to solve it?To solve the question we follow the steps in the given instructions.
The intercept is 1000Plot (0,1000)The slope is 150Make a rise of 150 units upwards and a run of 1 unit to the right. That gives our second point on the line (1,1150)We then join our line to get the required graph.Learn more about graphs here-

Step-by-step explanation:
the lines are parallel so
the angle above 85° is also 85° (vertical angles)the other angle in the triangle is 82° (180 - 98)82 + 85 = 167
167 - 180 = 13

1 tàu hỏa đi từ A đến B với quãng đường là 40km . Khi đi đến B , tàu dừng lại 20 phút rồi đi tiếp 30km đến C với vận tốc lớn hơn vận tốc khi đi từ A đến B là 5km/h . Tính vận tốc của tàu khi đi trên quãng đường AB . Biết thời gian kể từ khi tài xuất phát từ A đến khi tới C hết tất cả 2gio
Answer:
The speed from A to B is 40 km/h.
Step-by-step explanation:
Distance from A to B = 40 km
Distance from B to C = 30 km
Speed from A to B is v km/h
Speed fro B to C is v + 5 .
total time, t = 2 hours
Stopping time at B = 20 minutes
Let the time from A to B is t'.
[tex]t'=\frac{40}{v}[/tex]
Let the time from B to C is t''.
[tex]t''= \frac{30}{v+5}[/tex]
The total time is
[tex]\frac{40}{v}+\frac{30}{v+5}+\frac{20}{60}=2\\\\\frac{40 v + 200 + 30 v}{v^2 + 5 v}=\frac{10}{6}\\\\420 v + 1200 = 10 v^2 + 50 v\\\\10 v^2 -370 v - 1200 = 0 \\\\v^2 - 37v - 120 = 0 \\\\v^2 - 40 v + 3 v - 120 = 0 \\\\v(v - 40) + 3 (v - 40) = 0\\\\(v - 4)(v + 3) = 0\\\\v = 40 km/h or - 3 km/h[/tex]
Speed cannot be negative so the speed from A to B is 450 km/h.
A squirrel moved 200 meters in 7,200 seconds. What was the speed of the squirrel in meters per hour? *
Answer:
100 meters per hour.
Step-by-step explanation:
7,200 seconds / 60 = 120 minutes
120 minutes / 60 = 2 hours
200 meters / 2 hours = 100 meters
Since the squirrel moved 200 meters in 2 hours, the squirrel moved 100 metres per hour.

1. A square is lengthened by 6 units in one direction and by 5 units in the other
direction to make a rectangle, as shown in the diagram. The length of the side
of the original square is x units. What is the area of the whole new rectangle?
Answer:
a = x² + 11x + 30
Step-by-step explanation:
a = (x + 5)(x + 6)
multiply each term in the first set of parenthesis by each term in the second
a = x(x + 6) + 5(x + 6)
a = (x² + 6x) + (5x + 30)
combine like terms
a = x² + 11x + 30

Answer:
x = 15 and y = 7
Step-by-step explanation:
x = 2y + 1
x + y - 8 = 14
Let's substitute the value of x in the second equation:
(2y + 1) + y - 8 = 14
3y -7 = 14
3y = 14 + 7
3y = 21
y = 21/3
y = 7
And now you substitute the value of y in the first equation:
x = 2•7 + 1
x = 14 + 1
x = 15
Find the measure of the major arc
Answer:
Step-by-step explanation:
If the minor arc is 133, the major arc is going to be
Major arc = 360 - Minor arc
Minor arc = 133
Major arc = 360 - 133
Major arc = 227
Does this make sense? It should. If you put a line from C to A then extend it until it hit the circumference, you would get a diameter which is a 180o angle. The major arc through D is greater than 180. So 227 is a reasonable answer.
A woman is trying to remove holiday decorations from the roof of her house by climbing a ladder. The height of her house is 24 feet, and the distance she has to travel on the ladder is 30 ft. How far away is the ladder from the house?
Answer:
18 ft
Step-by-step explanation:
We are to determine the base given the hypotenuse and length.
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
30² = 24² + b²
900 = 576 + b²
b² = 900 - 576
b² = 324
square root = 18

What is Tangent and Secant Properties of a Circle?Circle is the collection of all points in a plane at a constant distance from a fixed point. The fixed point is known as the centre, and the constant distance is the circle’s radius. A line that intersects a circle in two distinct points is called a secant to the circle.
A line meeting a circle only in one point is called a tangent to the circle at that point. In this article, we will talk about the relative position of the circle and a line in the same plane. We will also examine the existence of tangents to a circle and their properties.
Using angle property between tangent and secant
