The slope of line segment AB is -3. What is the slope of a line segment parallel
to AB?
Answer:
-3
Step-by-step explanation:
We know that parallel lines have the same slope so if AB has a slope of -3 then all lines that are parallel have a slope of -3

5/4 divided by 10
I know this is supposed to be easy BUT i am counfused
Answer:
5/40
Step-by-step explanation:
Dividing fractions is the same as multiplying by the reciprocal:
5/4 ÷ 10
5/4 x 1/10
Multiply the numerators together and the denominators together:
= 5/40
So, the answer is 5/40
Answer:
5/40
Step-by-step explanation:
Skip, flip, multiply.
(5/4) / (10/1)
(5/4) * (1/10)
5/40
Instead of dividing by ten, think of you're multiplying by 1/10th. It's a lot easier on the brain.

Answered by GAUTHMATH
For right triangle EFD, m ∠F ≈ 26°, m ∠D ≈ 64.01° and FD = 89
The correct answer is an option (B)
What is hypotenuse?It is the longest side of the right triangle.
What is Pythagoras theorem?For a right triangle,
[tex]a^{2}+ b^{2} = c^{2}[/tex], where c is hypotenuse and a, b area other two sides of the right triangle
For given example,
We have been given a right triangle EFD with hypotenuse FD.
Also, EF = 80, ED = 39
Using the Pythagoras theorem,
[tex]\Rightarrow FD^{2}= EF^{2} + ED^{2}\\\\ \Rightarrow FD^{2}= 80^{2} + 39^{2}\\\\ \Rightarrow FD^2 = 6400 + 1521\\\\ \Rightarrow FD^2 = 7921\\\\\Rightarrow FD = 89[/tex]
Consider, sin(F)
[tex]\Rightarrow sin(F)=\frac{ED}{FD} \\\\\Rightarrow sin(F)=\frac{39}{89}\\\\ \Rightarrow sin(F)=0.4382\\\\\Rightarrow \angle F=sin^{-1}(0.4382)\\\\\Rightarrow \angle F=25.98^{\circ}\\\\\Rightarrow \angle F\approx 26^{\circ}[/tex]
Now, consider sin(D)
[tex]\Rightarrow sin(D)=\frac{FE}{FD}\\\\ \Rightarrow sin(D)=\frac{80}{89}\\\\ \Rightarrow \angle D = sin^{-1}(0.8988)\\\\\Rightarrow \angle D = 64.009^{\circ}\\\\\Rightarrow \angle D \approx 64.01^{\circ}[/tex]
Therefore, for right triangle EFD, m ∠F ≈ 26°, m ∠D ≈ 64.01° and FD = 89
The correct answer is an option (B)

The position of a particle moving along a coordinate axis is given by s(t) = t^2 - 5t + 1. Find the speed ,velocity and acceleration
Answer:
speed is 2t - 5
velocity is 2t - 5
a = 2 m/s²
Step-by-step explanation:
Given the position of a particle expressed as:
s(t) = t^2 - 5t + 1
speed v = ds/dt
ds/dt = 2t - 5
Hence the speed is 2t - 5
velocity can also be expressed as the speed, hence, velocity is 2t - 5
Acceleration is the change in velocity with respect to time. Hence;
a = dv/dt
a = 2 m/s²

help me in this plz....
Answer:
70. 8x⁴
71. 3n - 10
72. a/5 + 12
Step-by-step explanation:
70. a number "x" raised to the fourth = x⁴
Product of 8 and x⁴ = 8 × x⁴
= 8x⁴
71. 3 times a number "n" = 3 × n = 3n
3n decreased by 10 = 3n - 10
72. Quotient of a number "a" and 5 = a/5
12 more than a/5 = a/5 + 12

The ratio of grapes in a fruit salad to people it will serve is 13/3. How many people will be served if Deb is using 30 grapes?
Answer:
6 + 12/13, or 90/13 people will be served
Step-by-step explanation:
Ratios stay the same, no matter the quantity.
Given this, we can say that (13 grapes / 3 people) = (30 grapes / x amount of people)
13/3 = 30 / x
multiply both sides by 3 to remove a denominator
13 = 30 * 3 /x
multiply both sides by x to remove the other denonimator
13 * x = 30 * 3
13 * x = 90
divide both sides by 13 to isolate the x
x = 90/13 = 6 + 12/13 ≈6.92 people

if f(x)=3x and g(x)=1/3x, which expression could be used to verify that g(x) is the inverse of f(x)
a. 3x (x/3) ---> already tried this. it's wrong
b. (1/3x)(3x)
c. 1/3 (3x)
d. 1/3 (1/3x)
For g(x) to be the inverse of f(x) then f times g needs to equal g x f
F(g(x)) = 3 times (1/3x) = x
G(f(x)) = 1/3 times (3x) = x
The answer is c. 1/3(3x)

What is the equation in standard form for the line with slope 3 and y-intercept -4?
Answer: -3x+y=-4
Step-by-step explanation:
Standard form is Ax+By=C. In y=Mx+b form, it would be y=3x-4. To put it into standard form you subtract 3x from both sides. So then you have -3x+y=-4.
What is the common difference of the arithmetic sequence-20,-16,-12,-18
Answer:
common difference = 4
Step-by-step explanation:
common difference is the difference between the successive term and its preceding term.
let's take the successive term of -20 that is - 16
common difference (d) = successive term - preceeding term
= -16 -(-20)
= -16 + 20
= 4
if we take the successive term of -16 that is -12
we'll get the same common difference.
d = -12 -(-16)
d = -12 + 16
d = 4
this means that the common difference for an AP remains constant.
Si un proyectil asciende verticalmente, y después de 3 segundos alcanza su altura máxima, calcule la velocidad que lleva a la mitad de su trayectoria descendente
Answer:
The speed is 20.8 m/s
Step-by-step explanation:
If a projectile ascends vertically, and after 3 seconds it reaches its maximum height, calculate the velocity that it carries to the middle of its downward trajectory
Let the maximum height is h and initial velocity is u.
From first equation of motion
v = u + at
0 = u - g x 3
u = 3 g.....(1)
Use third equation of motion
[tex]v^2 = u^2 - 2 gh \\\\0 = 9 g^2 - 2 gh \\\\h = 4.5 g[/tex]
Let the speed at half the height is v'.
[tex]v^2 = u^2 + 2 gh \\\\v'^2 = 0 + 2 g\times 2.25 g\\\\v'^2 = 4.5\times 9.8\times9.8\\\\v' = 20.8 m/s[/tex]

Mr. Bartolome's salary is Php 18 500 per month. If 40% of his salary was spent for food., how much was spent for food?
Answer:
Amount of his salary spent on food = Php 7400
Step-by-step explanation:
Mr. Bartolome's salary = Php 18500
Percentage of salary spent on food = 40%
Amount of his salary spent on food = 40% of Php 18,500
= 40/100 × Php 18,500
= 0.4 × Php 18,500
= Php 7400
Amount of his salary spent on food = Php 7400
What is the area of this figure
Step-by-step explanation:
This can be split into 3 separate rectangles in two ways:
Way 1:
(9 * 8) + (6 * 5) + (3 * 3)
Step 1: The 18yd side is split into 9 (first rectangle), 6 (second rectangle), and 3 (third rectangle).
72 + 30 + 9
Step 2: Multiply each of the three products.
102 + 9
Step 3: Add from left to right
111 square yards
Way 2:
(9 * 3) + (15 * 2) + (18 * 3)
Step 1: This time, the 8yd side is split. 3 is used for rectangles 1 & 3, and 2 is used for rectangle 2.
27 + 30 + 54
Step 2: Multiply each of the three products.
57 + 54
Step 3: Add from left to right.
111 square yards.
Either way, you will still get 111 square yards as the answer.
