The measure of an angle is 50°.what is the measure of its complementary angle
Answer:
If "x" is the degree measure of the given angle, then the measure of its complement is (x+50) degrees.
And since these angles are complementary, you have this equation x + 50 = 90 °
x = 90 - 50
x = 40 °
The other angle is 40 °

What is the area of the trapezoid? The diagram is not drawn to scale.
A. 36 cm2
B. 9 cm2
C. 21 cm2
D. 16.5 cm2
Answer:
Area of trapezoid = 21 cm²
Step-by-step explanation:
Given:
Length of rectangular shape = 4 cm
Width of rectangular shape = 3 cm
Base of triangle = 3 cm
Number of triangle = 3 cm
Find:
Area of trapezoid
Computation:
Area of trapezoid = Area of middle rectangle + Number of triangle[Area of triangle]
Area of trapezoid = [l x b] + 2[(1/2)(b)(h)]
Area of trapezoid = [4 x 3] + 2[(1/2)(3)(3)]
Area of trapezoid = 12 + 9
Area of trapezoid = 21 cm²

Calcula la diagonal de un rectángulo cuyos lados tienen las siguientes medidas.
a. 5 dm y 4 dm
b. 8 cm y 6 cm
Las longitudes de las diagonales son √41 dm y 10 cm respectivamente
La medida de la diagonal de un rectángulo: de lado l1 y l2 es igual a
d² = (l1)² + (l2)²
La diagonal entonces es: utilizamos la fórmula dadas para los lados dados y aplicando raíz en la ecuación
A. 5dm y 4dm
d = √((5 dm)² + (4 dm)²) = √(25 + 16) dm = √41 dm
B. 8cm y 6cm
d = √((8 cm)² + (6 cm)²) = √(64 + 36) cm = √100 cm = 10 cm .
A rectangle measures 3cm by 4cm.What is the length of its diagonal ?
Answer:
5cm
Step-by-step explanation:
Given data
Length= 3cm
Width= 4cm
Applying Pythagoras theorem
z^2= x^2+y^2
z^2= 3^2+ 4^2
z^2= 9+16
z^2= 25
square root both sides
z= √25
z= 5cm
Hence the diagonal is 5cm

Find the area of the parallelogram
A. 11 Square units
B. 14 square units
C. 24 Square units
D. 12 square units
Therefore , the solution to the given problem of surface area comes out to be 24 square unit.
What does surface area is exactly?Shape is a unit used to describe how much overall space a material's surface occupies. A three-dimensional shape surface area is equal to the sum of its surroundings. The overall surface coverage of a multi shape is referred to as surface area. The volume of water of a cube featuring five rectangular faces can be calculated by adding up each face's specific area. As an alternative, you can identify the box's measurements using the formula below: Surface (SA) is equal to two times two times two.
Here,
The presented parallelogram has a height of 5-2 = 3 units.
The given parallelogram's basis is comprised of => 7 -(-1) units => 8 units.
As a result, the supplied parallelogram has a surface area of 8 * 3 = 24 square units.
As a result, 24 square units are required to solve the given area problem.

Hannah has a bag containing 2 Red, 4 purple, 4 Blue and 2 Green
marbles that all are the same size and shape. What is the
probability of randomly choosing a Red marble replacing it, and
then randomly choosing a Blue marble?
Answer:
1/18
Step-by-step explanation:
there are 12 marbles in the bag
P(choose red) = 2/12 = 1/6
P(choose blue after replacement) = 4/12 = 1/3
P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18
4 A roll of paper is shown below.
Tube
About how much cardboard is needed to make the inner tube for a roll of paper if the tube
has a diameter of 4.5 cm and is 24 cm long?
F 339 cm2
G 679 cm2
H 371 cm2
J
382 cm2
Answer:
339 cm²
Step-by-step explanation:
Using the relation for the surface area of a cylinder :
A = 2πrh
r = Radius = diameter / 2 = 4.5 / 2 = 2.25 cm
Height, h = 24 cm
A = 2 * 22/7 * 2.25 * 24
A = 339.29200 cm²
Surface Area =339 cm²
About 339cm³ of cardboard will be needed for the inner tube.
To make inner tube card board needed is 339 cm² of the material.
What is Surface area ?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Here, diameter = 4.5 cm
then, radius = 4.5/2 = 2.25 cm
height = 24 cm
Surface area = 2πrh
= 2 X 3.14 X 2.25 X 24
= 339.12 cm²
Thus, to make inner tube card board needed is 339 cm² of the material.

Answer:
3a²b
Step-by-step explanation:
The product of two algebraic
terms is 6a3b2. If one of the terms is
2ab, find the other term.
Let us represent
First term = a
Other term = b
a × b = 6a³b²
a = 2ab
b = ?
b = 6a³b²/a
b = 6a³b²/2ab
b = 6a³b²/2a¹b¹
b = (6 ÷ 2) × a^3 - 1 × b ^2 - 1
b = 3a²b
Therefore, the other term = 3a²b

equation for her salary last year : last year's salary = (4200 / 0.12) - 3000
$32,000
Step-by-step explanation:
Let x = last year's salary
this year's salary = 3000 + x
this equation can be used to determine how much she saved this year = 0.12 x (x + 3000) = 4200
to find last year's salary, make x the subject of the formula
4200 / 0.12 - 3000 = x

At your local store, you are given a coupon for 20% off any store item purchased on Monday. When you return to your store, you notice that an item (normal price = $50) is on clearance for 40% off. You are allowed to use the coupon on the clearance item. How much should you pay for the item? Should it be 60% off of the normal price?
Answer:
$24
no, it is 48% off normal price
Step-by-step explanation:
clearance price = normal price - value of the 40% discount
value of the 40% discount = 0.4 x $50 = $20
Price = $50 - $20 = $30
final price = clearance price - value of 20% coupon
value of 20% coupon = 0.2 x $30 = $6
final price = $30 = $6 = $24
total value off normal price = $24 /$50 x 100 = 48%

Joseph made a scale drawing of an Italian restaurant. The scale he used was 1 millimeter : 6 meters. The restaurant's kitchen is 24 meters long in real life. How long is the kitchen in the drawing
Answer:
4mm
Step-by-step explanation:
Joseph made a scale drawing of an Italian restaurant. The scale he used was 1 millimeter : 6 meters.
From the above question, our scale factor is given as:
1 millimeter : 6 meters.
1 mm = 6 m
Which also means
6m = 1 mm
The restaurant's kitchen is 24 meters long in real life. How long is the kitchen in the drawing?
Hence, we can calculate this as
6m = 1 mm
24 m = x mm
Cross Multiply
6 m × x mm = 24m × 1 mm
x mm = 24m × 1 mm/6m
x mm = 4 mm
Therefore, the length of the kitchen in the drawing is 4mm

K. 12
Answer:
54
Step-by-step explanation:
3*6*3=54
The solution is Option G.
The number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt is given by combination C = 54 ways
What are Combinations?The number of ways of selecting r objects from n unlike objects is:
ⁿCₓ = n! / ( ( n - x )! x! )
where
n = total number of objects
x = number of choosing objects from the set
Given data ,
Let the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt be C
Now , the equation will be
The total number of shoes = 3 pairs
The total number of pants = 3 pairs
The total number of shirts = 6 shirts
And , the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt is calculated by Combination , where
The number of ways of selecting 1 pair of shoes = ³C₁
The number of ways of selecting 1 pair of pants = ³C₁
The number of ways of selecting 1 shirt = ⁶C₁
So , the total number of ways = ³C₁ x ³C₁ x ⁶C₁
On simplifying the equation , we get
The total number of ways C = 3 x 3 x 6
The total number of ways C = 54 ways
Hence , the combination is C = 54 ways

How many adult tickets did he buy
please explain steps
Answer:
3 adult tickets and 5 children tickets.
Step-by-step explanation:
Make a chart:
1 adult + 7 children = 1(5)+7(3) = 26
2 adults + 6 children = 2(5)+6(3) = 28
3 adults + 5 children = 3(5)+5(3) = 30
4 adults + 4 children = 4(5)+4(3) = 32
5 adults + 3 children = 5(5)+3(3) = 34
6 adults + 2 children = 6(5)+2(3) = 36
7 adults + 1 child = 7(5)+1(3) = 38
The answer in bold is the only one that leads to $30, therefore he bought 3 adult tickets and 5 children tickets.

Area of 2 Bases = 2 (314) = 628
LA = Ch where C is the circumference of the base
LA = πdh = 3.14(20)(9) = 565.2
