Part ALet number of days be d, then the equation is:
50d + 200*0.6 = 1620Part BSolution of the equation
50d + 120 = 162050d + 120 - 120 = 1620 - 120 ⇒ subtraction property of equality50d = 150050d / 50 = 1500/50 ⇒ division property of equalityd = 30Part C30 days as abovef-4=6f + 26 what is f
Answer:
the answer is f=-6
Answer:
f = - 6
Step-by-step explanation:
Step 1:
f - 4 = 6f + 26 Equation
Step 2:
- 4 = 5f + 26 Subtract f on both sides
Step 3:
- 30 = 5f Subtract 26 on both sides
Step 4:
f = - 30 ÷ 5 Divide
Answer:
f = - 6

Calculate the SPEED of a
sprinter who ran 200 meters
in 20 seconds.
Speed = distance / time
Speed = 200 meters / 20 seconds
Speed = 10 meters / second
1 meter per second = 3.6 km per hour
10 meters per second x 3.6 = 36 km per hour
Answer: 36 kilometers per hour
Step-by-step explanation: Average speed = total distance / total time.

What slope is perpendicular to:
m = 5/8
The slope that is perpendicular to m = 5/8 is given by; m' = -8/5
When dealing with slope - intercept form of equation of a line, the general equation is;y = mx + c
where;
m is the slope
c is the y-intercept
Now, for a line to be perpendicular to a line above that has it's slope as m, the slope of this new line will be the negative inverse of the first slope. This is; m' = -1/mApplying that to our question, it means the slope that is perpendicular to m = 5/8 is; m' = -1/(5/8) = -8/5Read more at; https://brainly.com/question/21441448

In the right ∆ABC, BL is an angle bisector. If LB = 1.2 in and LC = 0.6 in. Find:
- The distance from L to AB.
- m∠ABC
Answer:
Distance of L from AB = 0.6 in.
m∠ABC = 60°
Step-by-step explanation:
Given:
LB = 1.2 in
LC = 0.6 in
We have to find the distance of point L to AB or length of LD.
From right triangle ΔBCL,
Sin(∠LBC) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{LC}{LB}[/tex]
= [tex]\frac{0.6}{1.2}[/tex]
= [tex]\frac{1}{2}[/tex]
m∠LBC = 30° [Since ∠LBC is an acute angle]
Since, ∠LBC ≅ ∠LBA
m∠LBA = 30°
Now from right triangle ΔLDC,
sin(∠LBA) = [tex]\frac{LD}{BL}[/tex]
sin(30)° = [tex]\frac{LD}{1.2}[/tex]
[tex]\frac{1}{2}=\frac{LD}{1.2}[/tex]
LD = 0.6
Therefore, Distance of point L from AB is 0.6 in.
m∠ABC = m∠ABL + m∠LBC
= 30° + 30°
= 60°
Write a linear function f with f(5)=7 and F(-2)=0.
Answer:
f(x)=x+2
Step-by-step explanation:
Slope= (7-0)/(5-(-2)) = 7/7 = 1
Y-intercept= 2
substitute the slope, 1, for m and the y-intercept, 2, for b to get:
f(x)=x+2
hope this helps!
The linear function f with f(5)=7 and F(-2)=0 is f(x) = x + 2
f(5) = 7
This means when x = 5 , y = 7
(5, 7)
f(-2) = 0
(-2, 0)
This implies when x = -2 , y = 0
Using the linear function formula,
y = mx + b
where
m = slope
b = y-intercept
Therefore, the function can be represented as follows:
m = 0 - 7 / -2 - 5 = -7 / -7 = 1
Therefore,
y = x + b
0 = -2 + b
b = 2
The function in relation to x can be represented as follows:
f(x) = x + 2
