A rhombus has sides 10 cm long and an angle of 60°. Find the diagonals of the rhombus.

Answer:

B

Step-by-step explanation:

Since all the expressions are on a straight angle (equalling 180) combine the expressions to form on big expression that is equal to 180 and solve.

6x - 10 + 4x + 6 + 7x + 14 = 180

17x + 10 = 180

      - 10    -10

17x = 170

÷17    ÷17

x = 10

Answer:

[tex] \rm Numbers = 4 \ and \ -3.[/tex]

Step-by-step explanation:

Given :-

And we need to find out the numbers. So let us take ,

According to first condition :-

[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]

Hence the numbers are 4 and -3

Step-by-step explanation:

[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

Answer:

16 rolls of ribon

Step-by-step explanation:

C = Dπ

d = r x 2

d = 100 x 2

d = 200

C = 200 x 3.14

C = 628

628 / 40 = 15.7

she should buy 16 rolls

Answer:

y = 114

Step-by-step explanation:

n + x = y

n - 20 = 85

n = 105

x=9

105 + 9 = 114

Answer:

11 and 23

Step-by-step explanation:

So, what is scaling?

Scaling is basically when a shape is inlarged or shruken by a specific amount on all sides.

In this case, one of the shapes side's is 10.

Now, they say that the scale value is more than 1. What does this mean?

It means that the new, scaled number is going to be at least as big as 10.

We dont have to worry about finding a exact number, since they do not give us any information to scale with.

So, all we have to do is look at the graph, and see what numbers are larger than 10.

Is 2 units larger than 10? No, thats only about 1/5 the orginal size, not larger than 1.

Is 5 units larger than 10? No, thats only abouit 1/2 the orginal size, not larger than 1.

How about 11? Is it larger than 10? Yes, its about 11/10 the orginal size, which is bigger than 1.

Finally we have 23? Is it larger than 10? Yes, its a little over 2 times bigger than the orginal size.

So your two answers are:

11 and 23

Answer: Try 5/8

Step-by-step explanation: Because 1/2 and 3/4 can also be written as 4/8 and 6/8. And that's how I got 5/8.

Hi! I believe that I have the answer.

My answer: 5/8.

1/2 can also be put as 4/8. 3/4 can also be put as 6/8. Right in the middle of 4/8 and 6/8 is 5/8.

I hope that helps!

Step-by-step explanation:

A. 5x=12x-14

you will  simplify the equation to the form, which is simple to understand  

5x=12x-14

We move all terms containing x to the left and all other terms to the right.  

+5x-12x=-14

We simplify left and right side of the equation.  

-7x=-14

We divide both sides of the equation by -7 to get x.  

x=2

B.   5B+12=BB=28

you will  move all terms to the left:

.5B+12-(BB)=0

you will  move all terms containing B to the left, all other terms to the right

.5B-BB=-12

Answer:

Angle 3 is 72

Angle 4 is 18

Angle 5 is 90

Angle 6 is 72

Step-by-step explanation:

Sum of straight angle is 180

So 180 = (90+18+x) for angle 3

Answer:

1 5/16 cups

Step-by-step explanation:
