Answer 1

Answer:

Step-by-step explanation:

[tex]15 \div 100 \times 420 = 63[/tex]

[tex]420 - 63 = 357[/tex]

15

[tex]15 \div 100 \times 357 = 53.55[/tex]

this is the 15% up amount

[tex]357 + 53.55 = 410.55[/tex]

nearest whole number is 411

what is the coefficient of 11

Answers

Answer:

The coefficient of a term will be the numerical value in the term.

Here there is no variable but, we consider it like this:

11 = 11x {Here x=1}

Thus the coefficient will be 11 as the coefficient of 11x is 11

Explanation of converting 11 into 11x (will be helpfull if you belong to lower grade):

We know that 11×1 is 11 itself. Thus if we take x with value of 1 then 11x will have the value of 11 itself.

What are Pythagorean triplets?  

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

What is pythgorean theorem ?

Pythagorean theorem is defined as  to find the unknown side of a right-angled triangle. eg, Two sides of a right-angled triangle are given as 6 cm and 9 cm, then the hypotenuse (the third side) can be calculated using the formula, h² = p2²+ b²; where 'h' is the hypotenuse and 'p' and 'b' are the perpendicular and base.

Here,
let the hypotenuse be h
now applying the Pythagorean theorem,

h² = 9² + 12²
h²= 81 + 144
h² = 225
h = √225
h = 15


Thus, the required length of the slanted area is 15 yards.

What is the slope of the line through the points (-2, -1) and (4, 3)

1. 3/2
2. 2/5
3. 2/3
4. 5/2

Answers

First find the numerator by looking for the difference between -2 and it’s axis. That would be 2. Then we count how far it is to 4, so the top would be 6. For denominator would be the same process. The distance from -1 to 0 is 1, and from 0 there to 3 is 4. 6/4 simplifies to 3/2. If you have questions just comment, that might not have made a ton of sense and I can reiterate :)

a rectangle that is 30 inches long and 10 inches wide can be divided into two congruent squares. True or false?

Answers

Answer:

False

Step-by-step explanation:

To split the rectangle into 2 parts, you can go one of two ways. One way would make the parts 15" by 10", and the other way would make the two parts 30" by 5". Neither way is equal on all sides, which means neither one is a square. That would make the statement false.

What two numbers have a difference of 5 and a product of 3.36?

Will mark brainliest if you show work.

Answers

Answer:

the two numbers are -0.6 and -5.6

Step-by-step explanation:

start with two equations then answer

x-y=5 and x*y=3.36

take the second equation and get only one variable at one end

which is x=3.36/y

then try to exchange x with 3.36/y in the other equation so it will be

(3.36/y)-y=5 so y=-5.6 then exchange y with -5.6 in any equation lets say  the first one it will be

x-(-5.6)=5 so x=-0.5
