six hundred kilograms of tea were packed in 500 g packets. how many packets of tea were there?
Answer:
1200 packets of tea
Step-by-step explanation:
Its because theres 1000 grams in 1kg so it would be 600000 grams and you would divided 600000 over 500 and get 1200
Can you mark brainlyist?
Answer:
1,200 packets of tea
Step-by-step explanation:
1. First, convert 600 kilograms into grams.
1 kilogram = 1,000 grams
So,
600 kilograms = 600,000 grams.
Now divide the previous value by 500.
[tex]\frac{600,000 g}{500 g} = 1,200[/tex]
Therefore, there are 1,200 packets of tea.

What is a quadratic equation?A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.
The standard form of the quadratic equation is,
[tex]ax^2+bx+c=0[/tex]
Here, (a,b,c) are the real numbers and x is the variable.
To find the value of x, the following formula is used,
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
The given equation is,
[tex]2(x+ 3)^2 - 4 = 0[/tex]
To solve this equation, we need to apply some mathematical operations over it. Let's start with opening the brackets.
[tex]2(x+ 3)^2 - 4 = 0\\2(x^2+6x+9)-4=0\\2x^2+12x+14-4\\2x^2+12x+12=0\\x^2+6x+7=0[/tex]
On comparing with standard equation we get,
[tex]a=1, b=6, c=7[/tex]
Put this values in the above formula,
[tex]x=\dfrac{-(6)\pm\sqrt{(6)^2-4(1)(7)}}{2(1)}\\x=\dfrac{-(6)\pm\sqrt{(6)^2-4(1)(7)}}{2(1)}\\x=-4.41,-1.59[/tex]

Given the function h of x equals 8 times the cube root of x minus 6 end root plus 16, what is the x-intercept of the function?
–6
–2
2
16
The x-intercept of the function h(x) is when the function h(x) = 0
The x-intercept of the function is -2
How to determine the x-intercept?From the question, the function is given as:
[tex]h(x) = 8 * \sqrt[3]{x - 6} + 16[/tex]
Set the function h(x) to 0, to calculate the x-intercept
[tex]8 * \sqrt[3]{x - 6} + 16= 0[/tex]
Subtract 16 from both sides of the equation
[tex]8 * \sqrt[3]{x - 6} +=-16[/tex]
Divide through by 8
[tex]\sqrt[3]{x - 6} =-2[/tex]
Take the cube of both sides
[tex]x - 6 =-8[/tex]
Add 6 to both sides
[tex]x =-2[/tex]

Victor is working on a project and has cut a number of wooden blocks of equal size that are represented by this right rectangular prism. He now needs to cover the wooden blocks on all sides with a red fabric.
How much fabric does Victor need in order to cover 12 of these blocks?
156 cm²
24 cm²
13 cm²
2 cm²
Answer:
(a) 156 cm²
Step-by-step explanation:
The total surface area of the 12 blocks can be computed by first finding the surface area of one block. That result can then be multiplied by 12. The area of one rectangular prism is given by the formula ...
A = 2(LW +H(L +W))
A = 2(4·1 +1/2(4+1)) = 2(4 +5/2) = 13 . . . cm²
The area of 12 such prisms will be ...
12 × (13 cm²) = 156 cm²
Victor needs 156 cm² of fabric to cover 12 blocks.
_____
Additional comment
This problem offers an opportunity to exercise your number sense. The area of the largest surface of one block is (4 cm)×(1 cm) = 4 cm². 12 of these surfaces will have an area of 48 cm². This is only part of the total area, so the only reasonable choice among those offered is 156 cm².
Answer:

Ethan drove the first half of his trip's distance at an average rate of 60 miles per hour, and the second half at an average
rate of 70 miles per hour. What was Ethan's average speed for the entire trip, in miles per hour?
Answer:
Simple
65 miles per hour on average
Step-by-step explanation:
You add 60 to 70 and then you divide them by 2
Which is
60 + 70 = 130
130 ÷ 2 = 65
The average speed Ethan will be 65 miles per hour on average.
What is speed?The speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
That Ethan drove the first half of his trip's distance at an average rate of 60 miles per hour, and the second half at an average rate of 70 miles per hour.
The average speed will be calculated as,
60 + 70 = 130
130 ÷ 2 = 65 miles per hour
Therefore, the average speed Ethan will be 65 miles per hour on average.

Step-by-step explanation:
A husband and wife are building a tiny house for a vacation getaway, and they want to measure the height of the roof of the house to see if they will be able to have a bedroom on the second floor. One side of the house is 18 ft long and the slant height of the roof along this side is 13 ft. The point on the roof's peak is above the center of the house. What is the height of the roof of the house? Round your answer to the nearest hundredth. Question 4 options: 9.38 ft 11.28 ft 15.21 ft 9.4
By using a right triangle as a model, we will see that height of the roof is 9.38 ft.
What is the height of the roof of the house?The slant height is equivalent to the hypotenuse of a right triangle, so we know the length of the base and the hypotenuse of a right triangle. The cathetus will be half of 18ft
We need to find the other cathetus, so we can use the Pythagorean theorem, if X is the other cathetus we will get:
X^2 + (9ft)^2 = (13 ft)^2
X = √( (13 ft)^2 - (9 ft)^2) = 9.38ft
So the height of the roof is 9.38 ft.

A plastic alphabet cube is 7 cm on each side. What is the surface area of the cube?
Answer:
In a cube, the length and width are the same, so both sides will be 7 cm, yielding an area of 49 square centimeters.
Step-by-step explanation:
Answer:
Cube's features;
6 sides to a cubeAll side lengths are equal, so all areas are the sameGiven this information, we must find the area of one side and multiply that area by 6 since there are 6 equal sides of the same area.
Formula for area of square:-
A = a^2
or
A = a · a
Where 'a' represents the length of one side.
Plug in values;
A = a^2
A = 7^2
A = 49 centimetres is the area of one side.
Now we find the areas of all sides (6 sides in total);
49(6)
= 294 is the surface area of the cube.
