Answer:
4355
Step-by-step explanation:
So first we will see how much is each hour
650 kilometres per hour.
So next we can work out how is 6 hours since that is easy.
650 X 6 = 3900
Next is the 42 mins
All you need to do is
650/ 60 = 65/6
65/6 X 42 = 455
Last step:
3900 + 455 = 4355
Done!
Hope I helped!

Answer:
- (5 +4 +3)×2 -1 = 23
- 5 +(4×3×2) -1 = 28
- 5×(4 +3 +2 -1) = 40
Step-by-step explanation:
The above expressions give the values you requested. I was able to form all integers 1-40 except 39.
_____
<em>Additional comment</em>
I used a computer program to evaluate different sequences of operations. Attached is one result for each integer 1-40 except 39. The notation here is postfix, but is not difficult to translate to infix with parentheses. Starting with the left-most operation (op), the pattern (a, b, op) → (a op b) is used. For example, the listing for 38 is 543+*21++, so this becomes 5*(4+3)+(2+1) = 38.
Answer:
x=−16/3 or x=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x2+10x−8=24
Step 2: Subtract 24 from both sides.
3x2+10x−8−24=24−24
3x2+10x−32=0
Step 3: Factor left side of equation.
(3x+16)(x−2)=0
Step 4: Set factors equal to 0.
3x+16=0 or x−2=0
Answer:
sure. x=12
Step-by-step explanation:
firstly! we know that the two sections equal 90 degrees (because a right angle is 90 degrees). so, take both of those sections, and put them equal to 90 in an equation.
it would look like this...
(x+42) + (3x) = 90
which is the same as...
<u>x + 42</u> + <u>3x</u> = 90. ignore the parenthesis. they're just for clarification. then we will solve for x!
add similar things together! see x and 3x? those are similar because they have x in them. (HOWEVER! if it's something like x² and x, do not add them together!) x is the same as 1x, by the way. so 1x + 3x. ignore the Xs and add the numbers. it becomes 4x
4x + 42 = 90
move 42 to the other side by minusing it on both parts of the equation!
4x = 90 - 42
4x = 48
divide 48 by 4 so x is alone. there ya go
Answer:
<u>Equation of a circle:</u>
- (x - h)² + (y - k)² = r², where (h, k) is the center and r- radius
<u>Substitute the given values to get the equation of this circle:</u>
- (x - (-5))² + (y - (-9))² = 7² ⇒
- (x + 5)² + (y + 9)² = 49
