1/2(2x - 1) = -1/5 -3/5 find x

Answers

Answer:

x = -3/10

Step-by-step explanation:

1/2(2x - 1) = -1/5 -3/5

Combine like terms

1/2(2x - 1) = -4/5

Multiply each side by 2

2* 1/2(2x - 1) = -4/5*2

2x-1 = -8/5

Add 1 to each side

2x-1+1 = -8/5 +1

2x = -8/5+5/5

2x = -3/5

Divide by 2

2x/2 = -3/5 * 1/2

x = -3/10

Marie made a model (shown below) of the square pyramid she plans to build when she grows up.

Find the surface area of the model please!

Answers

8 x 5 = 40 but since it is a triangle, you have to divide by two which is 20
20 x 4(because there are 4 triangles)
= 80
the surface area of the square pyramid is 80
Base: 8x8=64
Sides: 8x5=40 40 divide by 2= 20
20x4=80
80+64=144m^2

Container A was filled with water to the brim. Then, some of the water was poured into an empty Container B until the height of the water in both containers was the same. Find the new height in both water containers

Answers

28cm is the answer for your question!

The new height of the water container is equal to 66.7 centimeters.

For Container A:

Height = 40 cm.Length = 25 cm.Width = 30 cm.

For Container B:

Length = 18 cm.Width = 25 cm.

First of all, we would determine the volume of the water in Container A:

The volume of a rectangular prism.

Mathematically, the volume of a rectangular prism is given by this formula:

[tex]V = L \times W \times H[/tex]

Where:

V is the volume.L is the length.W is the width.H is the height.

Substituting the given parameters into the formula, we have;

[tex]V = 25 \times 30 \times 40[/tex]

V = 30,000 cubic centimeters.

Note: The volume of the two containers must be the same.

The new height:

[tex]30000=18\times 25 \times h\\\\30000=450h\\\\h=\frac{30000}{450}[/tex]

h = 66.7 centimeters.

On Monday, the low temperature in a city was -5.4°F. On Tuesday, the low temperature was 1.2°F colder than on Monday. On Wednesday, the low temperature was 3.7°F warmer than on Tuesday. What was the low temperature in the city on Wednesday?

Answers

Answer:

-2.9°F

Step-by-step explanation:

-5.4°F - 1.2°F = -6.6°F

-6.6°F + 3.7°F = -2.9°F

The low temperature in the city on Wednesday was -2.9°F

Hope this is helpful

Answer:

-2.9°F

Step-by-step explanation:

First subtract the temperature from Tuesday to Monday because it is getting colder, and you get 6.6 (-5.4 - 1.2 = -6.6)

Then add 3.7 because it is getting warmer and you get

-6.6 + 3.7 = -2.9

Answers

Even number 15% off: 5/10 or 1/2 odds
odd number greater than 6 -30% off odds: 2/10 or 1/5
Otherwise 20% off: 3/10 chance/odds
We have 10 numbers. If a customer gets an even number, they will get a 15 percent discount. We know that there are 5 odd and 5 even numbers, therefore there is a 5/10 (50 percent) probability a customer gets a 15 percent discount. We need to find out how many odd numbers are greater than 6. 7 and 9. There are two odd numbers greater than 6, so there is a 2/10 (20 percent) probability a customer gets a 30 percent discount. We also need to find the probability if a customer doesn’t meet any of that criteria. If we add 5/10 + 2/10, we will get 7/10. 10/10 - 7/10 = 3/10 (30 percent).

a bicyclist traveling at an average speed of 18 km/h takes 3 hours and 30 minutes to complete his journey. How many hours less will he take if he bicycles at a speed which is 3 km/h faster

Answers

Answer:

It will take him 0.5 (30 minutes) less hours if he bicycles at a speed that is 3km/h faster.

Step-by-step explanation:

18 km/h x 210 minutes = 3,780

3,780/21km = 180 minutes = 3 hours

If we multiply the speed by the time we can find the distance, using that we can find the time it takes to travel the same distance with more speed (21km/s this time).

Therefore, it will take 30 minutes less if he travels 2 km/s faster or 0.5 less hours

I hope this helps!

It will take him 1/2 an hour or 30mins
