what is the total distance travelled?
plzzzz helpppppppp
Answer:
Step-by-step explanation:
the corner points are O(0,0),A(45,10),D((100,10),E(120,0),G(160,0),H(200,5),F(240,5)
OA=√[(45-0)²+(10-0)²]=5√(9²+2²)=5√85≈46.1
DE=√[(120-100)²+(0-10)²]=√(400+100)=√500=10√5≈22.36
GH=√[(200-160)²+(5-0)²]=√1625≈40.31
Total distance travelled=46.1+22.36+40.31=108.77 km

Answer:
s = -15
Step-by-step explanation:
-12 + (-18) = -30
-30= 2s
-15 = s
-12 + (-18) = 2s
-12 - 18 = 2s
-30 = 2s
2s = -30
s = -15
5.) Write the explicit formula for the arithmetic sequence. -18, -7, 4, 15, 26,...
Answer:
an = -18 +11(n -1)
Step-by-step explanation:
We notice that the first term (a1) is -18, and the common difference (d) is -7-(-18) = 11. Filling these values into the form for the explicit formula gives ...
an = a1 +d(n -1)
an = -18 +11(n -1)

(a^(?))/(a^(10))= a^(4) help me
Answer:
a^? = 14
Step-by-step explanation:
a^? / a^10 = a^4
is also the same as
a^? - a^10 = a^4 ( due to laws of indices)
a^? = a^4 + a^10
a^? = a^14
the a's striking each other resulting in
? = 14
Eli is driving on a long road trip. He currently has 12 gallons of gas in his car. Each
hour that he drives, his car uses up 1.75 gallons of gas. How much gas would be in the
tank after driving for 4 hours? How much gas would be left after t hours?
Answer:
5 gallons would be left
Step-by-step explanation:
Answer:
There would be 5 gallons of gas after 4 hours.
There would be 12 - 1.75t after t hours.
Step-by-step explanation:
1.75 x 4 = 7
12 - 7 = 5

Susan enlarged a rectangle with a height of 5 cm and a length of 12 on her computer. the length of the new rectangle is 18 cm. find the height of the new rectangle.
the height of the new rectangle is______cm
Answer:
[tex]\huge\boxed{7.5 \ \text{cm}}[/tex]
Step-by-step explanation:
When we scale a rectangle, we multiply both the length and the width by the scale factor - or a constant value.
We can use a proportion to see how much to multiply by, where we have [tex]\frac{\text{height}}{\text{length}}[/tex].
[tex]\frac{5}{12} = \frac{x}{18}[/tex]
To solve for this proportion, we can cross multiply to find the value of x.
[tex]18 \cdot 5 = 90\\\\90 \div 12 = 7.5[/tex]
Therefore the height of the new rectangle is 7.5 cm.

The answer to the function is 102
First you must set up the equation
[tex]f(10)=3(10)(2)+6(10)-18[/tex]
Then you must multiply
[tex]f(10)=60 +60-18[/tex]
Finally, you must simplify like terms
[tex]f(10)=102[/tex]
caitlyn has $210 in her savings account and she has to pay her parents $5 each month.Santos has $90 dollars and he saves $5 dollars each month. At this rate, when will Caitlyn and Santos have the same amount of money ? How much will they each have?
Answer:
After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.
Step-by-step explanation:
Caitlyn's saving: -5x+210
Santos' saving: 5x+90
To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.
-5x+210 = 5x+90
(Add 5x on both sides)
210=10x+90
(Subtract 90 from both sides)
120=10x
(Simplify)
x=12
After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.

Which operation should be used to solve x + 7 = 19?
÷ 7
– 7
x 7
+ 7
Which operation should be used to solve x + 7 = 19?
÷ 7
– 7
x 7
+ 7
Answer:-7 is the correct answer.
Solution:Because when we'll use -7 then the 7 in the LHS will get cancelled.
x + 7 = 19
or, x + 7 - 7 = 19 - 7
or, x = 12

Answer:
Area = 90 units^2
Step-by-step explanation:
For the area of a triangle, we can simply use the following equation:
Area = ( 1 / 2 ) * Base * Height
We are given a base of 12 and a height of 15, so we can simply plug those values into the formula to find the area.
Area = ( 1 / 2 ) * Base * Height
Area = ( 1 / 2 ) * 12 * 15
Area = 6 * 15
Area = 90
Hence, the area of our triangle is 90 units^2.
Cheers.

What is 8.865 rounded to the nearest whole number?
Answer:
9
Step-by-step explanation:
8.865 to the nearest whole number is 9, nine is a whole number because there are no decimals following, and since the number "8" is greater than 5, we round up, which would cause it to be 8.900, so to the nearest whole number, it would be 9.
