help with this bounds question please
Answer: 6.68km/litre
Step-by-step explanation:
Distance(d) = 187km ( to 3 significant figures)
Petrol(p) = 28litres ( to 2 significant figures)
A number, x, rounded to 1 significant figure is 200
Write down the error interval for x
Calculating the lower and upper bound for both 'd' and 'p'
Upper bound 'd' = 187.5km
Lower bound 'd' = 186.5km
Upper bound 'p' = 28.5km
Lower bound 'p' = 27.5km
Therefore,
Petrol consumption (C) = d/p
Upper C = 187.5 / 28.5 = 6.57894
Lower C = 186.5 / 27.5 = 6.781818
Accuracy answer for C = (6.57894 + 6.781818) / 2 = 6.680379
= 6.68km/ litre ( to 3 significant figures)
To achieve a reasonable level of accuracy, the upper and lower bounds of P and D was used to calculate C, which was then averaged.
Using 3 significant figures ensure that we capture the C better, instead of early rounding.

-3x+7y=5x+2y Please HELP Complete the missing value in the solution to the equation.
(-5,_)
Answer:
(-5, -8); the missing value is -8
Step-by-step explanation:
First, you need to simplify the given equation to isolate y
1: -3x + 7y = 5x + 2y (Given)
2: 7y = 8x + 2y (Add 3x to both sides)
3: 5y = 8x (Subtract 2y from both sides)
4: y = 8/5x (Divide both sides by 5)
Now, you can use this to solve for the missing y in value set (-5, y)
where y = 8/5x and x = -5,
y = 8/5(-5)
y = -8
so, the missing value is -8
Isaac's goal is to earn at least $80 toward a week at soccer
camp. He has earned $32 so far. How much more does he need
to earn?
Which inequality fits this situation?
Answer:
x greather than equal to 48
Step-by-step explanation:
Look he needs AT LEAST $80. So the sign is greater than or equal to.
So the inequality is x+32 is greater than or equal to 80
x greater than or equal to 48
Jeremy built an office with a floor area of 55/14 square feet. The office is rectangular in shape. If the length of the room is 8 1/2 feet, what is the width of the room?
Answer:
110/289 feet
Step-by-step explanation:
Step one:
given data
Area of the floor= 55/14 square feet.
The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet
Step two:
The expression for the area of the room is
Area= L*W
55/14= 17/2*W
55/14=17W/2
cross multiply
17W*14=55*2
289W=110
divide both sides by 289
W= 110/289 feet

you multiply 80 x 4, then you get ur answer, 320.
Answer:
C. 320 (correct)
Step-by-step explanation:
If Samantha can type 40 words per minute, to find the number of words Samantha can type in 8 minutes, multiply 40 by 8.
40×8=320
Therefore, Samantha can type 320 words in 8 minutes.

6.A circle has a diameter of 11 inches. What is the circumference of the circle using ≈ 3.14? = . Single choice.
Answer:
Circumference of the circle = 34.54 inches
Step-by-step explanation:
Explanation
Given that diameter of the circle
d = 11inches
The radius of the circle
[tex]r = \frac{d}{2} = \frac{11}{2} = 5.5[/tex]
Circumference of the circle
= 2πr
= 2×3.14×5.5
= 34.54
Final answer:-
Circumference of the circle = 34.54 inches

A.) 18.7 units
B.) 10.5 units
C.) 9 units
D.) 13 units
Answer:
B.) 10.5
Step-by-step explanation:
Use ratios, but be careful.
AE/AD = AB/AC
14/18 = x/(x+3).
14x+42 = 18x
42 = 4x
x = 10.5
The value of x in the given figure is 10.5 so, option B.) 10.5 units is correct.
What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
or
[tex]\dfrac{a}{b}[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Using ratios;
AE/AD = AB/AC
14/18 = x/(x+3).
14x+42 = 18x
42 = 4x
x = 10.5
Thus, option B.) 10.5 units is correct.

PLZ HELP IM BEGGING
Answer:
-x+y= -14 (get this equation to where you can easily plug it in for a variable)
y= x -14
5x +6y =26 (plug the value above in for y and then solve)
5x + 6 (x-14) = 26 (use the distributive property)
5x +6x - 84 = 26 (combine like terms on the left side)
11x - 84 =26 (add 84 to both sides)
11x = 110 (divide both sides by 11 to isolate the x-variable)
x= 10 (this is the value for x. plug it into the easier equation and solve)
-(10) +y = -14
y= -4
(10, -4) (this is the solution for the system of equations)
