Answer:
Record speed of Usain Bolt in yards per second = 11.42 Yards (Approx.)
Step-by-step explanation:
Given:
Record speed of Usain Bolt = 100 meter in 9.58 second
1 meter = 1.094 yards
Find:
Record speed of Usain Bolt in yards per second
Computation:
Record speed of Usain Bolt = 100 meter in 9.58 second
1 meter = 1.094 yards
100 meter = 1.094 × 100 yards
100 meter = 109.4 yards
Record speed of Usain Bolt in yards per second = 109.4 / 9.58
Record speed of Usain Bolt in yards per second = 11.4196
Record speed of Usain Bolt in yards per second = 11.42 Yards (Approx.)
Find the angle for this problem
Answer:
ans: 31°
Step-by-step explanation:
<EFG = <EFH + <HFG
2x+52= 21 + ( x+31)
2x-x= 21 +31 -52
x= 0
so our question is to find <HFG so,
x+31°= 31°

The Park Protectors is a group of elementary students and teachers from 3232 schools who pick up trash at local parks. The line plot shows the tons of trash they picked up this year.
Answer:
[tex]Each = \frac{15}{128}[/tex]
Step-by-step explanation:
Given
See attachment for line plot
Required
Determine the total trash picked
The data on the line plot can be represented as:
[tex]Trash \to Schools[/tex]
[tex]\frac{1}{8} \to 6[/tex]
[tex]\frac{1}{4} \to 8[/tex]
[tex]\frac{1}{2} \to 2[/tex]
[tex]1 \to 0[/tex]
The total trash picked is:
[tex]Total = \frac{1}{8} * 6 + \frac{1}{4} * 8 + \frac{1}{2} * 2 + 1 * 0[/tex]
[tex]Total = \frac{3}{4} + \frac{8}{4} + 1+0[/tex]
Take LCM
[tex]Total = \frac{3+8+4+0}{4}[/tex]
[tex]Total = \frac{15}{4}[/tex]
The total picked by each school is:
[tex]Each = \frac{Total}{32}[/tex]
[tex]Each = \frac{15/4}{32}[/tex]
Rewrite as:
[tex]Each = \frac{15}{4*32}[/tex]
[tex]Each = \frac{15}{128}[/tex]
I need to know what this is? Can someone tell me… Honestly. What is the value of x?
Answer:
98º
Step-by-step explanation:
The sum of angles in a triangle is 180
---------------------
The missing angle in the triangle
180 - 45 - 53 = 82º
-------------------------
x is supplementary to 82º
x = 180 - 82
x = 98º

The Hogwarts Express train has reduced its one-way fare from 360 galleons to just 270 galleons. What is the percentage decrease in the fare? *
=======================================================
Work Shown:
A = old value = 360
B = new value = 270
C = percent change
C = (B-A)/A
C = (270-360)/360
C = -90/360
C = -0.25
C = -25%
The negative C value indicates we have a percent decrease.
Note how 25% of 360 = 0.25*360 = 90, meaning that the price has dropped by 90 galleons. And also note that 360-270 = 90 is that same figure of 90. This helps confirm the answer.

Answer:
-1 and -2
Step-by-step explanation:
The function 2 represented by the equation f(x) = -(x - 2)² + 5 has the larger maximum.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
The functions are given as:
Function 1
f(x) = -(x - 4)² + 1
Function 2:
f(x) = -(x - 2)² + 5
A quadratic function is represented as a (x - h)² + k, when a is negative then, the vertex of the function is a maximum. In both functions, the value of a is -1. This means that both functions are at a maximum
The values of k in both functions are k = 1 and k = 5. By comparison, 5 is greater than 1. Therefore, function 2 has larger maximum.

Question and choices are in the photo please explain the answer
Answer:
The answer is option C
Step-by-step explanation:
Product means that we have to multiply
So we multiply (3x - 4y) by (-2x + 5y - 6)
So the solution will be
3x(-2x + 5y - 6) - 4y(-2x + 5y - 6)
Note: don't forget that there are positive signs and negative signs in the equation
-6x² + 15xy - 18x + 8xy - 20y² - 24y
Group like terms
The like terms here are 15xy and 8xy so we group them
-6x² + 15xy + 8xy - 18x - 20y² - 24y
-6x² + 23xy + 8xy - 18x - 20y² - 24y
And that's your answer

Answer:
3(n-8)
Step-by-step explanation:
How much of a radioactive kind of xenon will be left after 15 days if the half-life is 5 days and
you start with 96 grams
Answer:
12 grams
Step-by-step explanation:
15/5 = 3 half lives
(1/2)³ = 1/8 of the original amount will remain
96 * 1/8 = 12 grams
Answer:
Step-by-step explanation:
Radioactive decay problems are very similar to compound interest formulas, except the rate is subtracted from one, instead of adding to one.
I.e.
mass at time t, m(t) = M (1 - r)^(t/h)
where
M = initial mass (grams)
m (t) mass left at time t (grams)
h = half-life in number of days
r = 0.5 from "half-life"
t = time lapse in number of days
Here
M = 96
h = 5
t = 15
m(15) = 96(1-0.5)^(15/5)
= 96 (1/2)^3
= 12 grams
A proportional relationship is shown in the table below: what is the slope and what numbers do i graph. ty besties
Answer:
The slope of the line is [tex]m = \frac{3}{5}[/tex] and the equation of the line is [tex]y = \frac{3}{5}\cdot x[/tex].
Step-by-step explanation:
From table we understand that slope of the line is constant, that is, for each change of [tex]x[/tex] there is one and only change in [tex]y[/tex], fulfilling the main characteristic of a line and we can determine the slope for every point of the line by means of the following expression:
[tex]m = \frac{y_{f}-y_{o}}{x_{f}-x_{o}}[/tex] (1)
Where:
[tex]x_{o}, x_{f}[/tex] - Initial and final x-coordinates of the line.
[tex]y_{o}, y_{f}[/tex] - Initial and final y-coordinates of the line.
If we know that [tex](x_{o}, y_{o}) = (0,0)[/tex] and [tex](x_{f},y_{f}) = (8,4.8)[/tex], then the slope of the line is:
[tex]m = \frac{4.8-0}{8-0}[/tex]
[tex]m = \frac{3}{5}[/tex]
From graph we conclude that x-intercept of the line is [tex]b = 0[/tex]. Hence, the equation of the line is [tex]y = \frac{3}{5}\cdot x[/tex] and we proceed to plot the expression with the help of a graphing tool.
Point slope form equations can be converted into slope intercept form. Distinguish whether the following
equations are the equations of the same line. Prove and explain your answer. Show your work for your
teacher to review.
y+ 1 = 5(x + 2) and y = 5x + 10
PLEASE HELP IM LITERALLY DYING
Please help I will give brainlist
Answer:
they are NOT the same
Step-by-step explanation:
y+ 1 = 5(x + 2) is y = 5x + 9
distribute the 5 and get 5x + 10
when you subtract the 1 from both sides the 10 becomes a 9
Given the inequality, select all the values of x that make that inequality true 3(2k-1)<9 0 1 2 3 4
Answer:
We have the inequality:
3*(2*x - 1) < 9
Where the given options are:
0, 1, 2, 3, 4
(you wrote k instead of x, but before you wrote "select all the values of x that make that inequality true", then I assume that the variable is x instead of k).
Again, let's start with the inequality:
3*(2*x - 1) < 9
and let's isolate the variable x.
(2*x - 1) < 9/3 = 3
(2*x - 1) < 3
2*x < 3 + 1 = 4
2*x < 4
x < 4/2
x < 2
Then all the values of x that are strictly smaller than 2 make the inequality true.
From the given options (0, 1, 2, 3, 4) the two that make the inequality true are:
x = 0
and
x = 1.

Kevin drew a diagonal inside a quadrilateral. He realizes the it always make 2 congruent isosceles triangleso. What kind of quadrilateral did Kevin use to draw the triangles ?
Answer:
The square is the quadrilateral.
Step-by-step explanation:
A quadrilateral is a 2 dimensional geometric shape. It has four sides which may be or may not be equal.
If a quadrilateral is a square and we make its diagonal so that we get two triangles.
These two triangles are isosceles triangle as the two sides are equal and the square has four equal sides and the triangles are congruent to each other.
here, the triangles ABC and ADC are congruent and isosceles.
The following is a parallelogram solve for the variables
Answer:
x = 51, y = 17
Step-by-step explanation:
Consecutive angles sum to 180° , so
x + 129 = 180 ( subtract 129 from both sides )
x = 51
-------------------------------------
Opposite angles are congruent, so
3y = x = 51 ( divide both sides by 3 )
y = 17
Step-by-step explanation:
x + 129° = 180°
x = 180°- 129°
x = 51°
3y + 129° = 180°
3y = 180° - 129°
3y = 51°
y = 51°/3
y = 17°
You borrow $3,897 for a loan for college expenses with a 2.5% interest rate. How much interest is charged on the loan
Answer:
Amount of interest pay per year = $97.5 (Approx.)
Step-by-step explanation:
Given:
Amount borrow for college expenses = $3,897
Rate of interest = 2.5%
Find:
Amount of interest pay per year
Computation:
Using Simple interest formula;
Simple interest = Amount borrow x Rate of interest x number of year
Amount of interest pay per year = 3,897 x 2.5% x 1
Amount of interest pay per year = 3,897 x 0.025
Amount of interest pay per year = 97.425
Amount of interest pay per year = $97.5 (Approx.)
