implicitAnnie and her family are on their way to visit some family friends who live 820 miles away from them. Based on the route they choose, they expect to complete their trip in three days. The distances and average speeds for the first two days driven are show below. First day: 6 hours at an average speed of 60 miles per hour Second day: 4 hours at an average speed of 65 miles per hour If the average speed on the third day is 50 miles per hour, how many more hours will it take for them to reach their family friends home?
Answer:
4 hours
Step-by-step explanation:
The distances and average speeds for the first two days driven are show below.
Step 1
We calculate the total distance covered in the first two days
First day: 6 hours at an average speed of 60 miles per hour
Hence:
1 hour = 60 miles
6 hours = x
x = 60 × 6
x = 360 miles
Second day: 4 hours at an average speed of 65 miles per hour
Hence:
1 hour = 65 miles
4 hours = x
x = 65 × 4
x = 260 miles
The distance covered for the first two days =
(360 + 260)miles
= 620 miles
Step 2
The total distance for the entire trip = 820 miles
Hence, the distance left to cover on the third day = (820 - 620)miles
= 200 miles
In the question, we are told:
If the average speed on the third day is 50 miles per hour,
The number of hours it will take for them to reach their family friends home is calculated using the formula
Time = Distance/Speed
Time = 200 miles/50 miles per hour
Time = 4 hours
I need to know how to solve this problem, you don't necessarily have to answer it, i just don't know the name and the steps to solving it because I missed out on a class that explained it, so I'm in the dark
Answer:
f(-3) = -16
Step-by-step explanation:
Given piecewise function is,
f(x) = 5x - 1 If x < -2
x + 3 If x ≥ -2
We have to find the value of he function when x = -3
Since x = -3 is less than x = -2,
Piece of the function to be considered,
f(x) = 5x - 1
f(-3) = 5(-3) - 1
f(-3) = -16

Answer:
A
Step-by-step explanation:
Answer:
The answer would be A
Step-by-step explanation:
Use the formula for |A| <= B which is: -B <= A <= B
For this example you would do:
1. Insert the numbers into the formula: -6 <= 2x - 8 <= 6
2. first do the math for -6 <= 2x-8 which is 1 <= x
3. then do the math for 2x - 8 <= 6 which is x <= 7
4. Put that together and you get 1 <= x <= 7

a=in
Answer:
a=9
Step-by-step explanation:
a^2+b^2=c^2
a^2+5.6^2=10.6^2
a^2+ 31.36=112.36
-31.36 -31.36
a^2=81
a=[tex]\sqrt{81}[/tex]
a=9
Answer:
9in
Step-by-step explanation:
is a right triangle so you can use Pythagorean Th.
(10.6)²= (5.6)² + a², subtract (5.6)² from both sides
(10.6)²- (5.6)² = a²
81 =a², squareroot both sides
√81= √a²
±9 = a we only consider the positive solution because we use it for measurements so a=9

Answer:
if ∠1 = 70°, then ∠5= 70°
Hence, option (A) is correct.
Step-by-step explanation:
Given
∠1 = 70°
To determine
We need to determine angle ∠5
From the diagram, it is clear that a transversal line crosses the two parallel lines, the angles in the matching corner would be corresponding angles.
We know that when two lines are parallel, their corresponding angles are equal.As angle ∠5 is the corresponding angle of angle ∠1 = 70°.
Also, the corresponding angles are equal here.Therefore,
if ∠1 = 70°, then ∠5= 70°
Hence, option (A) is correct.
can you see the specific pattern they follow?
(2,4,6,8...)(3,6,12,24...)( 5,10,15,20,...)
SOLVE AND SHOW WORK PLSSSS!! Find the length of the missing sides. Do not round (leave in simplified radical form).
Answer:
For the first triangle the missing sides are 7 and 7√2 For the second triangle,the missing sides are 13√3 and 13
Step-by-step explanation:
For the first triangle,
cos(45°)=7/hypotenuse
hypotenuse×cos45=7
hypotenuse×√2/2=7
hypotenuse=14/√2=7√2
We can now find the adjacent side using Pythagorean theorem,
√(7√2)²-7²=7
For the second triangle,
cos(30°)=adjacent/hypotenuse
but cos 30=√3/2
√3/2=adjacent/26(cross multiply and simplify)
26√3/2=13√3
To find the opposite length,
√(26)²-(13√3)²=13

Zoey is 362 meters below sea level while visiting a part of Israel. She descends 71 meters to visit the Dead Sea. Which integer represents the elevation, in meters, of the Dead Sea? i will give 25 points
Answer:
Zoey is -362 meters from sea level. She travels another -71 meters (notice the negative because she is now further away from sea level). She is now -433 meters from sea level.
Step-by-step explanation:
-362 (original elevation) + -71 (distance to new location) = -433 (total elevation)
Answer:
-433
Step-by-step explanation:
Zoey is already 362 below sea level.
Then she descends another 71 meters
So. . .
-362 - 71
This can also be written as -362 + (-71)
-433

OA.
the amount of the initial deposit
OB
the amount of the yearly earnings
OC. the rate at which the account is increasing
OD
the number of times the account has compounded since it was opened
Answer:
The correct option is;
C. The rate at which the account is increasing
Step-by-step explanation:
The given parameters are;
The rate at which the compound interest on the savings account is compounded = quarterly
The expression given by her banker to find the amount in the account after t years = 4,200(1.05)^(4t)
Therefore, the 1.05 = The rate at which the account is increasing

Answer:
side xy
Step-by-step explanation:
the shortest side is across from the smallest angle.
using the fact that all angles in a triangle add up to 180 degrees, we can figure out that angle z is 30 degrees
therefore, the opposite side from the smallest angle (angle z) is xy
It helps if you draw the triangle out or try to visualize it
Hope this helps:)

What is an equation of the line that passes through the points (0, 3) and (5,−3)?
Answer:
y = -6/5x + 3
Step-by-step explanation:
y = mx + c (or b, depending on where you're from)
Slope = m = -6/5
y = -6/5x + c
You can sub (0, 3) and (5, -3) into y = -6/5x + c and they both have the same answer where c = 3
Therefore, the equation is y = -6/5x + 3
