What is the area of the composite figure? -70 cm2 -100 cm2 -105 cm2 -130 cm2
Answers
Make two shapes out of it.
The bottom is a rectangle 14 x 5 = 70 square cm
The top is a triangle 1/2 x 12 x 5 = 30 square cm
Total area = 70 + 30 = 100 square cm
Answer:
100 cm²
Step-by-step explanation:
The composite shape can be cut into two shapes. One triangle and one rectangle. The sum of their areas is the area of the whole composite shape.
The area of the triangle:
b × h × 1/2
(14 - 2) × 5 × 1/2
60 × 1/2
= 30 cm²
The area of the rectangle:
l × w
14 × 5
= 70 cm²
Add the areas of the two shapes.
30 cm² + 70 cm²
= 100 cm²
The area of the composite shape is 100 cm².

A card is drawn at random from a standard pack of playing cards. Then a fair coin is flipped. What is the probability of selecting an Ace and the coin landing on tails?
Answers
Answer:
1/26
Step-by-step explanation:
In a standard pack of cards, there are 52 total cards and 4 aces, two black aces and two red aces.
The probability of selecting an ace is therefore:
4/52 = 1/13
The probability of flipping a coin and it landing on tails is:
1/2
Therefore, the probability of selecting an Ace and the coin landing on tails is:
1/13 * 1/2 = 1/26

mr anderson cuts a piece of metal in the shape of the triangle shown. The piece of metal has an area of 7 1/2 square feet. What is the base of the piece of metal ?
Answers
Answer:
3 ftStep-by-step explanation:
The question is incomplete. Here is the complete question.
"Mr. Anderson cuts a piece of metal in the shape of the triangle shown. The piece of metal has an area of 7 1/2 square feet. What is the base of the piece of metal? triangle 5ft high"
Area of the triangle = 1/2 * base * height
Given the area of the piece metal = 7 1/2 ft² and its height = 5ft (since the triangle is 5ft high). On substituting the values in the formula;
7 1/2 = 1/2* base * 5
15/2 = 5/2 * base
15 = 5 * base
base = 15/5
base = 3ft
The base of the piece of metal is 3ft

What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
From observation, it is given that the line segment MN which joins points M and N is parallel to the line JK. which follows from the fact that M and N are midpoints of KL and JL respectively.
Hence, it states that triangles NLM and JLK are congruent and by the ratio of corresponding sides equality:
NM/19.6 = 7.4/(2×7.4)
Solving;
NM = 19.6/2
NM= 9.8 meters.
This follows that, the ratio of corresponding sides of congruent triangles are equal.
The distance between points M and N is; 9.8 meters.

The volume of the cylinder is 230 cubic units. What is the volume of the
cone? Round to the nearest enth if necessary.
Answers
Answer:
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder
h represents the height of the cylinder
π is a constant
The formula for determining the volume of a cone is expressed as
Volume = 1/3πr²h
Where
r represents the radius of the cone
h represents the height of the cone
This means that the volume of the cone is 1/3 × volume of cylinder. Since the volume of the given cylinder is 230 cubic units, then
Volume of cone = 1/3 × 230 = 76.7 cubic units

Solve and check |2x − 1| = |4x + 9|
Answers
Answer:
x = -5 or x = -4/3
Step-by-step explanation:
First possibility.
|2x − 1| = |4x + 9|
2x - 1 = 4x + 9
2x - 4x = 9 + 1
-2x = 10
x = 10/-2
x = -5
Second possibility.
2x - 1 = - (4x+9)
2x - 1 = -4x - 9
2x + 4x = -9 + 1
6x = -8
x = -8/6
x = -4/3
Answer:
[tex] |2x - 1| = |4x + 9| [/tex]
this equation can be separated into 2 possible cases :
[tex]2x - 1 = 4x + 9[/tex]
and
[tex]2x - 1 = - (4x + 9)[/tex]
solve the 1st possible case:
[tex]2x - 1 = 4x + 9[/tex]
[tex]2x - 4x = 9 + 1[/tex]
[tex] - 2x = 10[/tex]
[tex]x = - \frac{10}{2} [/tex]
[tex]x = - 5[/tex]
solve the 2nd possible case:
[tex]2x - 1 = - (4x + 9)[/tex]
[tex]2x - 1 = - 4x - 9[/tex]
[tex]2x + 4x = - 9 + 1[/tex]
[tex]6x = - 8[/tex]
[tex]x = \frac{ - 8}{6} [/tex]
[tex]x = - \frac{4}{3} [/tex]
so the x value for this equation is:
x = -5 or x = -1.333
straight line graphs: find the equation of the lines shown
Answers
Answer:
1. y = -2n + 9
2. y = (1/2)x + 1/2
Step-by-step explanation:
1.
The equation of a line is denoted by y = mx + b, where m is the slope and b is the y-intercept.
Slope is calculated by taking two coordinates and dividing the difference of the y-coordinates by the difference of the x-coordinates. The y-intercept is where the line intersects the y-axis.
Let's choose any two points on the line: (4, 1) and (3, 3). Then:
slope = m = (3 - 1) / (3 - 4) = 2 / (-1) = -2
Now, we can also see that at the point (0, 9), the line intersects the y-axis, so that means b = 9.
The equation is thus y = -2n + 9.
2.
Let's again choose any two points to find the slope: (1, 1) and (3, 2). Then:
slope = m = (2 - 1) / (3 - 1) = 1/2
We can see that the line crosses the y-axis at the point (0, 1/2), so that means b = 1/2.
The equation is thus y = (1/2)x + 1/2.
