Find the value of x for the square and triangle. If necessary, round to the nearest tenth.
Answer:
The value of x is 2.11
Step-by-step explanation:
area of a triangle=95m^2
perpendicular(p)=3x
base(b)=3x
now,
area of right angled triangle=1/2*b*p
or,95=1/2*3x*3x
or,95*2=9x
or,190=9x
or,190/9=x
x=21.11

Answer:
Y = -4.5x
Step-by-step explanation:
First evaluate: -16x to the second power = -256x
Then add like terms: -256x + 238x = -18x
Then divide both sides by -18: -18x divided by -18/ 81 divided by -18
Which leaves you with y = -4.5x

Terry is buying juice. He needs 3 liters. A half-liter of juice costs $2.39. A 250-milliliter container of juice costs $1.69. What should Terry buy so he gets 3 liters at the lowest price? Explain.
Answer:
Terry should buy the half liters.
Step-by-step explanation:
Terry should buy the half liters because 6 half liters (equivalent to 3 liters) is $14.34, compared to 12 250 milliliter containers (equivalent to 3 liters) is $20.28.
Answer: Terry should buy the HALF LITER of juice.
Step-by-step explanation: Terry should buy the half liters because 6 half liters (3 liters) is $14.34, whilst the 12 250 milliliter containers cost more ($20.28) but are still equivalent to 3 liters just like the 6 half liters.

Answer:
b² + c² = 47
Step-by-step explanation:
Expand (b + c)² = 61
⇒ (b + c)(b + c) = 61
⇒ b² + 2bc + c² = 61
Substitute bc = 7 into b² + 2bc + c² = 61:
b² + 2(7) + c² = 61
b² + 14 + c² = 61
To determine b² + c² simply subtract 14 from both sides of the equation:
b² + c² = 47

running out of constant rate Gina ran 15 miles in a time of 150 minutes how many minutes does it take to run in 6 minutes?
Answer:
.6 or 6/10 of a mile
Step-by-step explanation:
Divide 150 by 15 which equals 10 which means that Gina was moving at 1 mile in 10 minutes. So now we know that Gina was moving at .1 or 1/10 mile a minute so 6 minutes is 6/10 or .6 of a mile.
Which of the following is equal to the expression 6 x 19?
Also this is using the distributive property too!!
Explanation:
Think of 19 as 10+9
This means 6 x 19 = 6 x (10 + 9) = (6 x 10) + (6 x 9) through the distributive property. We multiply the outer 6 by each term inside the parenthesis.

find the volume of a cone with a diameter of 12 m and a height of 9 m
The volume of the cone with a diameter of 12m and height of 9m = 108π m³.
∴ Option D. is the right option.
What do we mean by volume?The volume of a 3-Dimensional object is the maximum space it can occupy.
What do we mean by a cone?A cone is a 3-Dimensional object that has a circular base and reduces gradually throughout, ending up with a pointed head.
How do we solve the given question?We are asked to find the volume of the cone with a diameter of 12m and a height of 9m.
The formula for the volume of a cone is as this:
Volume = (πr²h)/3 cubic units.
For the given cone height (h) = 9m, radius (r) = diameter/2 = 12/2 = 6m.
We substitute values of h and r in the formula to get,
Volume = (π*(6²)*9)/3 m³ = (π*(36)*9)/3 m³ = (324π)/3 m³ = 108π m³.
∴ The volume of the cone asked = 108π m³.

Diego runs for 32 seconds at -8.1 meters per second. What is his finish point?
Andre runs for 35 seconds and finishes at -285 meters. What is his velocity?
Answer:
Lin = 8.2 m/s x 25 s = 205 m (Finish Point)
Elena = V = 250 m / 28 s V = 8.93/s (Velocity)
Diego = -8.1 m/s x 32 s = -259.2 meters (Finish Point)
