Each year for 4 years, the time it takes you to run a mile decreases by 6 seconds. Find the total change in time.
Answer:
To set up this equation, we want to find the total change in time (x) over 4 years if every year your time decreases by 6 seconds. Our equation should look something like this:
x = 6*4
To solve this, you just have to multiply 6*4!
x = 24
This means that over 4 years, you have cut 24 seconds off of the time it takes you to run a mile! Your total change in time would then be 24 seconds!

Find the total surface area of this prism
｡☆✼★ ━━━━━━━━━━━━━━ ☾
area of triangle = (b x h) / 2
area of triangle = (14 x 24) / 2
A.I.T = 168 cm^2
As there are 2 triangles, double this value
Area of triangles = 168 x 2 = 336 cm^2
Area of rectangle = 25 x 10 = 250
As there are 2 of the same rectangle, double this value
250 x 2 = 500
Area of rectangle = 10 x 14 = 140 cm^2
Add all the values together to get the total surface area
140 + 500 + 336 = 976
The answer is 976 cm^2

Answer:
C.
Step-by-step explanation:
The change rate is just to big to differ from 2-4 and M isnt the same rate as P in the problem, so the answer would be C. (hoped this helped :D
Answer:
A
Step-by-step explanation:
Rate of change of the functions is measured by their slopes.
Function M
Calculate slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (0, 1) ← 2 ordered pairs from the table
m = [tex]\frac{1+9}{0+2}[/tex] = [tex]\frac{10}{2}[/tex] = 5
Function P
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 7x + 9 ← is in slope- intercept form
with m = 7
Thus
Their rates of change differ by 2 → A

What additional information is needed to prove that the triangles are congruent using the AAS congruence theorem? LO ≅ LM OA ≅ MA AngleLOA ≅ AngleLMA AngleLAO ≅ AngleLAM
Answer:
∠LOA≅∠LMA
Step-by-step explanation:
The first two options are incorrect because you need one more set of congruent ANGLES, not SIDES. The last option would prove congruency, but through ASA, not AAS. So it would be the third option.
For both triangles to be congruent by the AAS congruence theorem, the additional information needed is: C. ∠LOA ≅ ∠LMA.
What is the AAS Congruence Theorem?The AAS congruence theorem states that two triangles are proven to be congruent when they have two pairs of corresponding congruent angles and a pair of non-included sides that are congruent.
From the diagram given, we already known that:
LA ≅ LA [congruent side]
∠OLA ≅ ∠MLA [one pair of congruent angles]
Therefore, an additional information that would make both triangles congruent by the AAS congruence theorem is: C. ∠LOA ≅ ∠LMA.

4*2=8
8*2=16
16*2=32
The sequence 1, 2, 4, 8, 16, 32 is geometric sequences, Option D is correct.
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the preceding term by a fixed constant called the common ratio.
Let us check all the options for geometric sequence
2, -2, 2, -2, 2-2, 2
This is not a geometric sequence because the terms are not multiplied by a common ratio to get the next term.
1.4. 9, 16, 25, 36, 49
This is not a geometric sequence because there is no common ratio between the terms.
10.5, 2.5, 1.25, 0:625, 0.3125
This is not a geometric sequence because there is no common ratio between the terms.
1, 2, 4, 8, 16, 32
This is a geometric sequence because each term is obtained by multiplying the previous term by the common ratio of 2.
Therefore, the sequence 1, 2, 4, 8, 16, 32 is geometric sequences, Option D is correct.

How you would solve the following problem: 4.5 + h = 7.3.
The grassy area of a playground has a side length of x and a side of width of x + 3 what is the area of the playground?
A. A(x)=x^2+3x
B. A(x)=x^2+x+3
C. A(x)=2x+3
D. A(x)=x^2+3
Answer:
A
Step-by-step explanation:
We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.
Here, the length is l = x and the width is w = x + 3. So, plug these in:
A = lw
A = x(x + 3)
Expand this out:
A = x² + 3x
The answer is thus A.
Answer:
A
Step-by-step explanation:
Area = length × width
Area = x × (x + 3)
A(x) = x²+ 3x

Write a linear equation in standard form for the line that goes through (4,3)
and (8,2).
Answer:
Ax + By = C
A, B and C can be any number--including negative numbers, zero and one! So examples of standard form can look like this:
3_x_ + 7_y_ = 10, where A = 3, B = 7 and C = 10.
Or they can look like this:
x + 5_y_ = 6. In this case, A = 1, B = 5 and C = 6.
Or this:
8_y_ = 9. In this case, A = 0, which is why x does not appear in the equation. B = 8 and C = 9, as you would expect.
And here's one more:
3_x_ − 5_y_ = 12. Here, A = 3, B = −5 and C = 12. Notice that in this case, B is negative five!
The standard form of a linear equation is Ax + By = C, where A, B and C can be any number.
A random number generator app on your phone generates two numbers between 0 and 8. What is the probability that the first number is less than three and the second number is 6? Express the probability as a fraction in simplest form.
Answer:
1/27
Step-by-step explanation:
There are 9 numbers between 0 and 8. 3 of them are less than 3 (0, 1, and 2), and 1 of them is 6.
The probability is therefore (3/9) (1/9) = 1/27.

It takes 24 electricians 36 days to wire a new housing subdivision. How many days would 32 electricians take to do the same job?
Answer:
They would take 27 days
Step-by-step explanation:
If 24 electricians can to the work to wire a new housing subdivision in 36 days.Therefore,32 electricians will take lesser days to complete it.
So,let the no. of days needed to complete the work by 32 electricians be x;
As the no.of days are decreasing with the increasing no. of electricians;it can be called as inverse variation
Therefore,
24 × 36 = 32 × x
x = 24 × 36 ÷ 32 (by cross multiplication method)
x = 27
Thus,It will take 27 days for 32 electricians to complete the same work which 24 electricians needed to complete in 36 days

Riko wants to find the distance between the points (−2, −3) and (2, −5). His work is shown. The distance is 8 units. Riko correct? Explain why or why not.
Answer:
incorrect
Step-by-step explanation:
The calculation he has done only calculates the distance between the y- coordinates of the points.
Calculate the distance d using the distance formula.
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (2, - 5)
d = [tex]\sqrt{(2+2)^2+(-5+3)^2}[/tex]
= [tex]\sqrt{4^2+(-2)^2}[/tex]
= [tex]\sqrt{16+4}[/tex]
= [tex]\sqrt{20}[/tex] = [tex]\sqrt{4(5)}[/tex] = 2[tex]\sqrt{5}[/tex] ← exact distance
Answer:Sample Response: No, Riko is not correct. The points do not have the same x-coordinates. If you connect the points, they do not form a horizontal or vertical line, so you cannot count spaces or use absolute value to find the distance.
