A boat traveled 27 miles in 2 hours at this rate how many miles will the boat travel in1/2 hour
Answer:
The boat would travel 6.75 miles in a 1/2 hour.
Step-by-step explanation:
If the boat travels 27 miles in 2 hours, you would take 27 and divide it by 2 to find out how many miles it travels in 1 hour. (27/2= 13.5 miles). Then you would take 13.5 miles and divide it by 2 again to find how many miles it traveled in 1/2 an hour. (13.5/2 = 6.75 miles).
Betty babysat for 3 hours each night for 12 nights. She earned a total of $288 babysitting. Betty wants to calculate her hourly rate. How much did Betty earn per hour babysitting?
Answer:Betty earned $8 per hour babysitting
Step-by-step explanation:
Number of hours worked per day =3
Number pf nights worked =12
Number of hours wored for 12 nghts =3x12=36hours
Now if 36 hours earned her $288
1 hour will earn her=( 288 x 1) / 36 = 8 hours
(20a-10) - (12a-3) subtract
Answer:
8a - 7
Step-by-step explanation:
First, subtract 12a from 20a
20a - 12a
= 8a
Now, subtract -3 from -10.
Subtracting a negative number is the same as adding a positive number, so add 3 to -10.
-10 + 3
= -7
Put together 8a and -7
8a - 7
So, the simplified expression is 8a - 7
Yesenia has a 13 ft ladder that she placed against a
wall. How far up the wall will the ladder reach when the
base of the ladder is 5 ft from the wall?
Answer:
12 ft
Step-by-step explanation:
Using formula (pythagorean theorem)
a² + b² = c²
Where :
13 = c
and 5 = a
5² + b² = 13²
25 + b² = 169
169 - 25 = b²
144 = b²
Sq root b = 12
It will reach up 12 ft.

Answer:
PLATO
Step-by-step explanation:
Answer:
The coordinates of point D will vary based on the point location, but the resulting slope of the line through points C and D will be the same.
A = (-3, 3), B = (-1,-1)
Slope of AB = (YB−YA) / ( XB –XA) =−1−3 / −1−(−3)= − 4 / 2= −2
D = (-1,6), C = (1,2)
Slope of DC = (YC−YD) / (XC−XD)= 2 – 6 / 1−(−1)=−4 / 2=−2

Step-by-step explanation:
Graph h(x) = -|x- 6| + 3.
Answer: Shift the graph to the right by 6, and up by 3.
Step-by-step explanation: If a number is in parentheses or absolute value lines, use the inverse sign. If it’s outside of the parentheses, move it like normal.
To graph the function h(x) = -|x - 6| + 3, we can follow a step-by-step approach:
Step 1: Determine the key points:
Identify the vertex: The vertex of the absolute value function y = |x| is at (0, 0). In this case, since we have y = -|x - 6| + 3, the vertex is obtained by shifting the vertex (0, 0) horizontally by 6 units to the right and vertically up by 3 units. Therefore, the vertex is at (6, 3).
Find additional points: Choose some x-values on both sides of the vertex to determine corresponding y-values. Let's choose x = 0, 3, 6, and 9.
Step 2: Calculate the y-values:
For x = 0: h(0) = -|0 - 6| + 3 = -|-6| + 3 = -6 + 3 = -3.
For x = 3: h(3) = -|3 - 6| + 3 = -|-3| + 3 = -3 + 3 = 0.
For x = 6: h(6) = -|6 - 6| + 3 = -|0| + 3 = -0 + 3 = 3.
For x = 9: h(9) = -|9 - 6| + 3 = -|3| + 3 = -3 + 3 = 0.
Step 3: Plot the points:
Plot the points (0, -3), (3, 0), (6, 3), and (9, 0) on a coordinate plane.
Step 4: Draw the graph:
Connect the plotted points smoothly. Since we have an absolute value function with a negative sign, the graph will be an upside-down V-shape, opening downwards, with the vertex at (6, 3).
Here's a visual representation of the graph of h(x) = -|x - 6| + 3:
Please note that the graph above is a rough representation and may not be perfectly to scale.

In AKLM, mZK = 101° and mL = 67º. Which statement about the sides of AKLM
must be true?
LM > MK > KL
LM > KL > MK
O KL > MK > LM
O KL > LM > MK
MK > KL > LM
O MK > LM > KL
Answer:
LM > MK > KL
Step-by-step explanation:
Given: ΔKLM , m∠K = 101° , m∠L = 67°
By definition of a triangle's sum of interior angles, the ∑ΔKLM's interior angles is 180°, ∴ m∠M = 180 - (101 + 67) = 12°
By the usage of law of sines, the opposite side's measurement is contingent with the angle measurement. The smaller the angle measurement, the shorter the opposite side.
Note the angles:
m∠M = 12° ∴ Side LK = shortest
m∠K = 101° ∴ Side ML = longest
m∠L = 67° ∴ Side KM = in between
∴ LK < KM < ML
A) LM > MK > KL is your answer.
