Answer:
1.32lb
Step-by-step explanation:
We will first have to calculate the grams to kilogram,
600g = 0.6kg
Since 1 kilogram represents 2.2 pound we will multiply 0.6 by 2.2 to get the pounds
0.6 * 2.2
= 1.32lb

Answer:
A 7/25
Step-by-step explanation:
The cosine of an angle is equal to the sine of its complement. In a right triangle, angle A is the complement of angle B. So, ...
cos(A) = sin(B)
cos(A) = 7/25
How many solutions does the following equation have?
6(2x – 6) = -7(-2x + 4)
Answer:
6(2x-6)=-7(-2x+4)
6×2x-6×6=-7×(-2x)-7×4

what is 7x-21=x+3
need step by step
Answer:
[tex]\boxed {x = 4}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]7x - 21 = x + 3[/tex]
-Take [tex]x[/tex] and subtract it from [tex]7x[/tex]:
[tex]7x - 21 - x = x - x + 3[/tex]
[tex]6x - 21 = 3[/tex]
-Add both sides [tex]21[/tex]:
[tex]6x - 21 + 21 = 3 + 21[/tex]
[tex]6x = 24[/tex]
-Divide both sides by [tex]6[/tex]:
[tex]\frac{6x}{6} = \frac{24}{6}[/tex]
[tex]\boxed {x = 4}[/tex]
Thus, the value of [tex]x[/tex] is [tex]4[/tex].

Solve 4(x-1) = 2(6-2x)
Answer:
x=2
Step-by-step explanation:
4(x-1) = 2(6-2x)
x=2
Answer:
x=2
Step-by-step explanation:
4(x-1)=2(6-2x)
4x-4=12-4x
Add 4 to both sides
4x=16-4x
Add 4x to both sides
8x=16
Divide by 8 on both sides
x=2

what is the system of inequalities for the graph below?
Answer:
hi do You have Instagram?
9514 1404 393
Answer:
y ≥ -2x +1y ≤ 2x +4Step-by-step explanation:
The downward-sloping line has a y-intercept of 1 and a slope of -2, so its equation is ...
y = -2x +1
The graph is shaded on and above that line, so the inequality it represents is ...
y ≥ -2x +1
__
The upward-sloping line has a y-intercept of +4 and a slope of +2, so its equation is ...
y = 2x +4
The graph is shaded on and below that line, so the inequality it represents is ...
y ≤ 2x +4
Then the system of inequalities is ...
y ≥ -2x +1
y ≤ 2x +4

A ladder is placed against a wall such that the top is 8 feet above the ground. If the ladder is 10 feet long, how far away from the wall is the base of the ladder
Answer:
6 feet
Step-by-step explanation:
Consider the right triangle formed by the wall, ladder and ground.
Let the distance the ladder is from the wall be d , then
Using Pythagoras' identity in the right triangle
The square on the hypotenuse ( ladder) is equal to the sum of the squares on the other 2 sides ( wall and d ), then
d² + 8² = 10²
d² + 64 = 100 ( subtract 64 from both sides )
d² = 36 ( take the square root of both sides )
d = [tex]\sqrt{36}[/tex] = 6
That is the ladder is 6 feet away from the wall
Payton spent half of her weekly allowance on clothes. To earn more money, her parents let her clean the oven for $8. What is Payton weekly allowance if she ended with $15
Answer:
Payton's weekly allowance is $14.
Step-by-step explanation:
If she ended up with $15 after earning $8, then we to subtract 15 by 8.
15 - 8 = 7
If Payton spent half of her allowance before earning more money from her chore, then her allowance must be 7 times 2.
7 x 2 = 14.
Therefore, Payton's weekly allowance is $14.
Hope this helps! :)

Deon throws a ball into the air. The height h of the ball, in meters, at time t seconds is modeled by the function h(t)=-5t^2+14t+3 When will the ball hit the ground
Answer:
The time the ball will hit the ground is 1.4s
Step-by-step explanation:
Given;
function of the ball's motion; h(t)= -5t²+ 14t + 3h
The final velocity of the ball, v , is given as;
v = dh/dt
v = -10t + 14
When the ball hits the ground, the final velocity, v = 0
v = -10t + 14
0 = -10t + 14
10t = 14
t = 14 / 10
t = 1.4s
Therefore, the time the ball will hit the ground is 1.4s

Ahmed recorded the temperature outside his window one morning. On the second day, the temperature went up 7 degrees. On the third day, the temperature went down 10 degrees. On the fourth day, the temperature went down 6 degrees, and it was 1°F.What was the temperature on the first day?
Answer:
[tex]-2^{\circ}\text{F}[/tex]
Step-by-step explanation:
Let [tex]x[/tex] be the temperature on the first day
Second day temperature
[tex]x+7[/tex]
Third day temperature
[tex]x+7-10[/tex]
Fourth day temperature was [tex]1^{\circ}\text{F}[/tex]
[tex]x+7-10+6=1\\\Rightarrow x+3=1\\\Rightarrow x=1-3\\\Rightarrow x=-2^{\circ}\text{F}[/tex]
On the first day the temperature was [tex]-2^{\circ}\text{F}[/tex]
Amir has a bag of dimes and quarters. He has a total of 31 coins worth $5 20. Let x represent the number of dimes and y represent the number of quarters. Which system of equations would be used to find out how many dimes and quarters Amir has?
Answer:
This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?
x = dimes x = 0.10 or 0.1
y = quarters y = 0.25
31 coins
worth $5.20 = 5.2
x + y = 31
0.1x + 0.25y = 5.2

Mr. Myers wants to join a music club. The 1st choice music club charges a $5 sign-up fee and $1 each song. The Superstar music club charges no sign-up fee and charges $3.50 each song. After how many songs will the cost of the music clubs be equal? 1st choice Music Equation: ______ Superstar Music Club Equation: ______ Solution: _____ This was due yesterday and I'm having trouble with this stuff, I'm in advanced math but my teacher moves way too quickly, I would appreciate it if you could help me out.
Answer:
1st choice Music Equation: [tex]\$(x+5)[/tex]
Superstar Music Club Equation: [tex]\$3.50x[/tex]
Solution: 2
Step-by-step explanation:
Given that:
1st choice music club:
Charges for one song = $1
Charges for sign - up = $5
Let the number of songs = [tex]x[/tex]
Total cost = [tex]\$5+\$1\times x = \$(x+5)[/tex]
Superstar music club:
No sign up fee and
Charges for one song = $3.50
Total cost = [tex]\$3.50x[/tex]
Given that, cost of each music club becomes equal:
Putting them same:
[tex]x+5=3.5x\\\Rightarrow 2.5x = 5\\\Rightarrow \bold{x =2}[/tex]
After 2 songs, the cost of both the clubs will become equal.
The tape diagram represents the ratio of the numbers of planets in two different solar systems. There are 8 planets in Solar System B. How many planets are in Solar System A?
The correct answer is 6 planets
Explanation:
The image presented shows the ratio of planets in solar system A vs those in solar system B. In this way, the general ratio is 3 : 4 or 3 to 4; this means for each 4 four planets in solar system B there are 3 planets in solar system A and vice versa. Now, to find the total of planets in system A if there are 8 planets in system B, follow this process:
8 planets / 4 = 2 planets - This means each of the sections in the diagram represents 2 planets
2 section x 3 = 6 planets as in the solar system A there are 3 sections and each of this represents 2 planets, the total of planets in this system are 6
This result can also be found by converting the ratio to a fraction and multiplying this by the 8 planets
8 planets x [tex]\frac{3}{4} = \frac{24}{4} = 6[/tex]
At 8:00 am, the temperature was -10°F. The temperature dropped 3 degrees per hour for the next 5 hours. What was the temperature at 1:00 pm?
Answer:
-25 °F
Step-by-step explanation:
First, we would be multiply 3 by 5 to find the number we would be subtracting from the original
3 * 5 would give us 15
Then we subtract -10 by 15 and get -25 °F
The temperature at 1:00 PM would be -25 °F
