ABCD is a rhombus. Find m
Answer:
angle ABD=28 degrees
Step-by-step explanation:
Diagonals of a rhombus are perpendicular so all angles at point E are 90 degrees.
Diagonals of a rhombus also bisect the corner angles.
therefore:
angle CBD=ABD
angle CBD=90-62=28 degrees
so angle ABD=28 degrees
Martin is laying out a design for the tiles on a section of his bathroom floor. He will use 1 black tile for every 4 white tiles to have total of 20 tiles in the design. How many of each type of tile will Martin use?
Answer:
[tex]Black = 4[/tex]
[tex]White = 16[/tex]
Step-by-step explanation:
Given
[tex]Black : White = 1 : 4[/tex]
[tex]Total = 20[/tex]
Required
Determine the number of each type used
Convert each ratio to fraction.
For Black, we have:
[tex]Black = \frac{1}{1 + 4} = \frac{1}{5}[/tex]
For White, we have:
[tex]White = \frac{4}{1 + 4} = \frac{4}{5}[/tex]
The number of tiles for each is then calculated as:
[tex]Black = \frac{1}{5} * Total[/tex]
[tex]Black = \frac{1}{5} * 20[/tex]
[tex]Black = \frac{20}{5}[/tex]
[tex]Black = 4[/tex]
[tex]White = \frac{4}{5} * Total[/tex]
[tex]White = \frac{4}{5} * 20[/tex]
[tex]White = \frac{4 * 20}{5}[/tex]
[tex]White = \frac{80}{5}[/tex]
[tex]White = 16[/tex]
A graduated cylinder is filled with 20ml of water. Then, an 8g marble is dropped into the cylinder, causing the volume to change to 24ml. What is the density of the marble?
Answer:
The density of the marble is 2,000 kg/m³
Step-by-step explanation:
The given parameters for finding the density of the marble are;
The volume of water in the graduated cylinder, v₁ = 20 ml
The mass of the marble dropped into the graduated cylinder, m = 8 g
The new volume of the cylinder after the 8 g marble is dropped into the cylinder, v₂ = 24 ml
Therefore, the volume of the marble, v = v₂ - v₁
Substituting the known values gives;
The volume of the marble, v = 24 ml - 20 ml = 4 ml
Density, ρ = Mass, m/(Volume, v), the units of density is kg/m³
Therefore, the density of the marble, [tex]\rho _{marble}[/tex], is given as follows;
[tex]\rho _{marble}[/tex] = m/v = (8 g)/(4 ml) = 2 g/ml
1 g/ml = 1 kg/l = 1,000 kg/m³
∴ [tex]\rho _{marble}[/tex] = 2 kg/l = 2,000 kg/m³.

Which function's graph is shown below?
Answer:
B: y=sinx
Step-by-step explanation:
the parent sine function is a repeating function that goes from 0 to 1, with sin(0)=0 sin(pi/2)=1 sin(pi)=0 sin(3pi/2)=-1 and sin(2pi)=0, π≈3.1415926 and we see on this graph that the graph matches at all these major points.
the cosine parent function is essentially the same thing but shifted to the left by π/2. It is essential to familiarize yourself with the unit circle and the key angles and their respective sin and cosine values.
The answer is y = sin x!!

Jennifer bought a mountain bike priced at $315.00. She received a 19% discount because the dealer was overstocked. She had to pay an 8% sales tax on the amount she actually paid for the bike what was the total cost of the bike including tax
Answer:
$275.562
Step-by-step explanation:
Step 1
Find the discounted price
Jennifer bought a mountain bike priced at $315.00. She received a 19% discount because the dealer was overstocked.
Discount = $315 × 19%
= $59.85
Discounted price = $315 - $59.85
= $255.15
Step 2
Sale Tax
She had to pay an 8% sales tax on the amount she actually paid for the bike
Hence:
$255.15 × 8%
Sale Tax = $20.412
Step 3
The total cost of the bike including tax is calculated as:
$255.15 + $20.412
= $275.562

Need Help Please answer and Find the measure of the exterior angle of the triangle.
Answer:
20
Step-by-step explanation:
Answer:
y°=70
Step-by-step explanation:
the angles inside a triangle must add up to 180 degrees, and thus the unknown interior angle is 180°-40°-30°=110°
this interior angle and the exterior angle are supplementary to each other and thus 110°+y°=180°
so y°=70°
you could also have used the theorem that states that the interior angles sum not adjacent to the exterior angle would equal the exterior angle

The scatter plot below shows the relationship between hours spent on video games and hours spent on homework last week for students in Ginny's class.
Which of the following is the best estimate of the average change in homework time that was associated with a 1-hour increase in time spent on video games?
Answer:
-4/3 hrs
Step-by-step explanation:
trust me I just got it right ;)
The hour change rate is [tex]-\frac{4}{3}[/tex]
What is scatter plot?'A scatter plot uses dots to represent values for two different numeric variables.'
According to the given problem,
Since the data shows mostly a linear trend, we can draw a line to estimate the rate of change.
The line approximately goes through (0,23) and (12,7).
Using the slope formula,
m = [tex]\frac{y_{2}- y_{1} }{x_{2}-x_{1} }[/tex]
Substituting the respective values,
m = [tex]\frac{7-23}{12-0}[/tex]
m = [tex]-\frac{4}{3}[/tex]
Hence, we can conclude that each additional hour spent on video games is associated with approximately a [tex]-\frac{4}{3}[/tex] hour change in time spent on homework on average.

Answer: (2, 5)
Step-by-step explanation:
y = 2x + 1 y = 4x − 3
Eliminate the equal sides of each equation and combine.
2x + 1 = 4x − 3
Solve 2x + 1 = 4x − 3 for x.
Move all terms containing x to the left side of the equation.
Subtract 4x from both sides of the equation.
2x + 1 − 4x = −3
Subtract 4x from 2x.
−2x + 1 = −3
Move all terms not containing x to the right side of the equation.
Subtract 1 from both sides of the equation.
−2x = −3 − 1
Subtract 1 from −3.
−2x = −4
Divide each term by −2 and simplify.
x = 2
Evaluate y when x = 2.
Substitute 2 for x. y = 4 (2) − 3
Simplify 4 (2) − 3.
Multiply 4 by 2.
y = 8 − 3
Subtract 3 from 8.
y = 5

Is quadrilateral UVWX a parallelogram? Why or why not?
Answer:
C
Step-by-step explanation:
Slope of UV = 0 = Slope of XW
So UV is parallel to XW.
Slope of UX = [6-(-4)]/[-7-(-3)] = -5/2
Slope of VW = [6-(-4)]/(0-4) = -5/2
Slope of UX = Slope of VW i.e. UX is parallel to VW.
It is a parallelogram because opposite sides are parallel.
Answer:
Yes, because opposite sides are parallel.

Here is a diagram of a softball field:
Outfield
Infield
110 ft
250 ft
Use this diagram to answer the questions below.
Use 3.14 to represent and round your answer to the nearest whole number. Type your answers in the boxes below.
HINT: For this problem we are going to assume the infield is a regular circle. Solve as if it is a circle.
1. The fence around the field (the whole perimeter of the shape) is about
feet
2. The area of the outfield is about
ft
a. The Length of the fence around the field = perimeter of quarter circle is 892.7 ft.
b. The area of the outfield is 39,584 sq. ft..
What is the circle about?Note that:
Perimeter of circle = 2πrPerimeter of a quarter circle = 2r + 1/4(2πr).a. The length of the fence around the field = perimeter of the quarter circle fence
= 2r + 1/4(2πr).
r = 250 ft
Put in the value
The length of the fence around the field = 2(250) + 1/4(2 × π × 250)
= 892.7 ft.
b. Size of the outfield = area of the full field (quarter circle) - area of the infield (cicle)
= 1/4(πR²) - πr²
R = radius of the full field = 250 ft
r = radius of the infield = 110/2 = 55 ft
Put in the values
Size of the outfield = 1/4(π × 250²) - π × 55²
= 49,087 - 9,503
= 39,584 sq. ft.

Step-by-step explanation:
2. You need to work a total of 44 hours per week at your two jobs. Your job as a store clerk pays
$5.50 an hour, and your job as a landscaper pays $6.00 an hour. You need to earn $250.00 per
week to cover your expenses. Which system of equations shows the various numbers of hours
you can work at each job? C is the number of hours worked as a clerk, while L is the number of
hours worked as a landscaper.
A.
C +L = 44
5.50C + 6L = 250
B.
C + L = 250
5.50C + 6L = 44
C.
5.50C + L = 44
C + 6L = 250
D.
C + L = 44
6C + 5.50L = 250
The equation shows the various numbers of hours you can work at each job are 5.50C + 6L = 250, and C + L = 44, so option A is correct.
What is the equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
Given:
You work a total of 44 hours per week at your two jobs, Your job as a store clerk pays $5.50 an hour, and your job as a landscaper pays $6.00 an hour, and the total money to be earned is $250 per week.
Calculate the equation as shown below,
5.50C + 6L = 250 and C + L = 44
Solve the above equation by using the elimination method,
C = 28 hours and L = 44 - 28 = 16 hrs
Therefore, the equation shows the various numbers of hours you can work at each job are 5.50C + 6L = 250, and C + L = 44.
