Step-by-step explanation:

https://www.symbolab.com/

Answer:

Okay so you are going to get -5/12

Step-by-step explanation:

what you are going to do first is look at your signs the plus and minus signs are there to try and mix you up. What you are doing is subtracting all three of these fractions... Okay?

3/4 - 1/2 - 2/3

What you need to do is turn 1/2 into 1/4 because when adding or subtracting fractions you need to have the same denominator.

Subtract:

3/4 - 2/4 = 1/4

Now you are going to have to multiply the tops and the bottom of 2/3 by four (you should get 8/12) and multiply 1/4 (top and bottom) by three (you should get 3/12). This allows you to subtract 2/3 and 1/4 to get a product of 5/12. You can not simplify this fraction any further so you have your answer!

-5/12

*EDIT

Don't forget the minus sign.

Answer:

1. x=−2y+3

2. [tex]\frac{5}{2} y - 5[/tex]

Step-by-step explanation:

Step-by-step explanation:

2x+4y = 6

-2x +5y = 10

9y = 16

y = 16/9

2x+ 4(16/9) = 6

2x +64/9 = 54/9

2x = -10/9

x = -5/9

wow those are ugly numbers

Answer:

C:  triangle

Step-by-step explanation:

the cross section is a triangle that is smaller than the base triangle.

The solution is : Second option is correct. O B. a circle, can not form a perpendicular bisector.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

Since we know that to form perpendicular bisector .

We need atleast two lines which form right angle.

So, right triangle can form perpendicular bisector with base and height.

Parallel lines can also form perpendicular bisector if a line is drawn from mid point of one line to mid point of another line.

A line segment can form perpendicular bisector.

But circle can't as it is curved shape it needs line to make perpendicular bisector.

Hence, Second option is correct. O B. a circle, can not form a perpendicular bisector.

Answer:

96

Step-by-step explanation:

The volume of the square pyramid is 96 cm³.

You can locate the extent of a normal square pyramid with the use of the volume formula= base location² × height / 3. Take be aware that the bottom vicinity equals the square of the pyramid's base side period. However, the peak is the perpendicular distance between the pyramid's base and the pyramid's vertex.

By using the given formula, we get

V= a² h/3

=6² * 8 / 3 = 96

The answer is 96 cm³.

The volume of a pyramid is found using the formula V = (1/3) B*h, where 'B' is the base area and 'h' is the height of the pyramid.

Answer:

  False

Step-by-step explanation:

Corresponding angles in similar triangles are congruent. The similarity statement tells you angle B corresponds to angle Y, so those angles are congruent. The sines of congruent angles are identical.

Answer:

58

Step-by-step explanation:

3 * 3 is 9 + 7 * 7 is 49 so 9 + 49 equals 58

Answer:

58

Step-by-step explanation:

Following the Order of Operations, you'd put parenthesis around the two threes and the two sevens, making it (3*3)+(7*7) which equals 9 + 49 and results in the number 58.

Answer:

13.7477270849 to 19.7230829233.

Step-by-step explanation:

1. Using the pythagorean theorem, a²+b²=c², we try different combinations of given lengths 10 and 17.

2. If 10 and 17 are legs and 10²+17²=√389 = 19.7230829233, then c=19.7230829233.

3. If 10 is a leg and 17 is a hypotenuse,

10²+b²=17²

100+b²=289

b²=189

b=13.7477270849

4. The case of 17 is a leg and 10 is a hypotenuse is not possible because the hypotenuse is the longest side.

5. The range of the length of the 3rd side is 13.7477270849 to 19.7230829233.

Answer: 280 children

Explanation: Each grade has 70 kids. You have 4 total grades (3rd, 4th, 5th, and 6th grade). You have to add the number of kids you have in every grade. In this case, 70 children in 3rd grade, 70 children in 4th grade, 70 children in 5th grade, and 70 children in 6th grade. The problem would look like this:

70 + 70 + 70 + 70

Then your answer is 280 when you add them all together!
