-59 = m - 11, m = ? i dont know the answer
Answer:
m = -48
Step-by-step explanation:
m - 11 = -59 (add 11 on both sides)
m = -48
Hope this helps!!
Answer:
m = -48
Step-by-step explanation:
m - 11 = -59
you add the 11 to both sides crossing it out from the left side and then you get an equation that looks like this.
m = -59 + 11
Now you can just solve it like a simple subtraction problem, -59 + 11 = -48
Hope I was able to help :)
During a weekend trip, Selena drove 4 times as far as Jason. Altogether they drove 380 miles. Which equation can be solved for x, the number of miles Jason drove?
Answer:
4x+x=360 (whole equation)
x=72 (answer)
Step-by-step explanation:
Let the distance driven by Jason be x.
Selena drove four times as far.
Hence, distance Selena drove is 4x.
They drove 380 miles altogether.
Hence, 4x + x = 380
5x = 380
x = 72
Hope this helped!
A pebble is dropped into a deep well and 3s later the sound of a splash is heard as the pebble reaches the bottom of the well. The speed of sound in air is about 340 m/s. How long will it take fir the pebble to hit the water? How long does is take for the sound to reach the observer? What is the depth of the well? (I need the equation)
Answer:
[tex]2.89\ \text{s}[/tex]
0.11 seconds
[tex]37.4\ \text{m}[/tex]
Step-by-step explanation:
[tex]t_1[/tex] = Time taken by the pebble to hit the water
[tex]t_2[/tex] = Time taken by the sound to travel to the observer
[tex]t_1+t_2[/tex] = Time taken by the observer to listen to the splash after stone is thrown = 3 s
[tex]t_1=3-t_2[/tex]
a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
[tex]u_s[/tex] = Speed of sound = 340 m/s
The distance traveled by the pebble
[tex]s=ut+\dfrac{1}{2}at_1^2\\\Rightarrow s=0+\dfrac{1}{2}\times9.81(3-t_2)^2\\\Rightarrow s=4.905(9+t_2^2-6t_2^2)[/tex]
Distance traveled by the sound
[tex]s=u_st\\\Rightarrow s=340\times t_2[/tex]
The distance traveled by the sound and the pebble is equal
[tex]4.905(9+t_2^2-6t_2)=340\times t_2\\\Rightarrow 9+t_2^2-6t_2=\dfrac{340}{4.905}t_2\\\Rightarrow 9+t_2^2-6t_2=69.32t_2\\\Rightarrow t_2^2-75.32t_2+9=0\\\Rightarrow t_2=\frac{-\left(-75.32\right)\pm \sqrt{\left(-75.32\right)^2-4\times \:1\times \:9}}{2\times \:1}\\\Rightarrow t_2=75.2,0.11[/tex]
Since [tex]t_1+t_2=3[/tex] the value of [tex]t_2[/tex] cannot be greater than 3.
So, time taken by the sound to reach the observer is 0.11 seconds.
Time taken by the pebble to hit the water is [tex]t_1=3-t_2=3-0.11=2.89\ \text{s}[/tex]
Depth of the well is [tex]s=340t_2=340\times 0.11=37.4\ \text{m}[/tex]
please, i need to answer this for tomorrow and i dont get it!
Answer:
1.72r²
Step-by-step explanation:
total Rectangle area = 4r*2r = 8r²
total circles area = 2(π r²) = 2*3.14*r² = 6.28r²
then:
the area of the shaded region:
= 8r² - 6.28r²
= (8-6.28)r²
= 1.72r²
Answer:
2r²(4 - π)
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of rectangle - area of 2 circles
The rectangle has a length of 4r and a width of 2r , then
A = (4r × 2r) - (2πr²)
= 8r² - 2πr² ← factor out 2r² from each term
= 2r²(4 - π)

Answer:
d=1
Step-by-step explanation:
distribute 0.5 through the parentheses
3.5d+2=7-1.5d
move variable to the left-hand side and change its sign
3.5d+1.5d+2=7
move constant to the right-hand side and change its sign
3.5d+1.5d=7-2
collect all like terms
5d=7-2
subtract the numbers
5d=5
divide both sides
d=1

second one.
60/10=6.
Answer:
see below
Step-by-step explanation:
just cross multiply:
10 (x) = 3 (100)
x = 300 / 10
x = 30
same as above, just cross multiply:
100 (x) = 60 (10)
x = 600 / 100
x = 6

Henry incorrectly said the rate 1/5 pound/1/10 gallon can be written as the unit rate 1/50 pound per gallon . What is the correct unit rate? What was Henry's likely error?
Answer:
What is the correct unit rate?
The correct unit rate = 2 pound per gallon
What was Henry's likely error?
Henry's likely error was that instead of dividing the fractions he multiplied them
Step-by-step explanation:
Henry incorrectly said the rate 1/5 pound/1/10 gallon can be written as the unit rate 1/50 pound per gallon .
What is the correct unit rate?
The correct unit rate
= 1/5 / 1/10
= 1/5 ÷ 1/10
= 1/5 × 10/1
= 2 pound per gallon
What was Henry's likely error?
Henry's likely error was that instead of dividing the fractions he multiplied them
1/5 / 1/10
Henry calculated it : = 1/5 x 1/10 = 1/50
This is wrong.
The correct step is given below
1/5 / 1/10
= 1/5 ÷ 1/10
= 1/5 × 10/1
= 2 pound per gallon
How does the graph of g(x)=⌈x⌉+7 differ from the graph of f(x)=⌈x⌉?
The graph of g(x)=⌈x⌉+7 is the graph of f(x)=⌈x⌉ shifted up 7 units.
The graph of g(x)=⌈x⌉+7 is the graph of f(x)=⌈x⌉ shifted right 7 units.
The graph of g(x)=⌈x⌉+7 is the graph of f(x)=⌈x⌉ shifted down 7 units.
The graph of g(x)=⌈x⌉+7 is the graph of f(x)=⌈x⌉ shifted left 7 units.
The +7 at the end effectively adds 7 to each y coordinate output, which is why the entire graph shifts up 7 units. For instance, a point like (1,2) moves to (1,9) after shifting up 7 units.
Side note: The function f(x)=⌈x⌉ is the ceiling function. It takes any decimal value and rounds it up to the nearest whole number. If you had an input like x = 2.01 then the output would be y = 3 even though 2.01 is closer to 2 than it is to 3.
