The lengths of the diagonals of a rhombus are 4x and 6x. What expression gives the perimeter of the rhombus?
Answer:
Expression gives the perimeter = 4x√17
Step-by-step explanation:
∵ The diagonals of the rhombus ⊥ to each other and
bisects each other
∴ Half the longest diagonal = 8x/2 = 4x
∴ Half the shortest diagonal = 2x/2 = x
Use Pythagoras theorem to find the length of the side of the rhombus
∴ The length of the side = √[(4x)² + (x)²] = √[16x² + x²] = √(17x²)
∴ S = x√17
∵ Perimeter of the rhombus = 4 × S
∴ P = 4 × x√17 = 4x√17
Answer:
the correct answer is 4x✓13.
I need help....Does anybody know the answer?
Answer:
4/5
Step-by-step explanation:
8/15 = 8/15
3/5 = 9/15
2/3 = 10/15
11/15 = 11/15
We see that the pattern is that the terms increase by 1/15 as they move up.
Thus, the next term in the sequence is 12/15, which can be simplified to 4/5.

Find the surface area of a cuboid with lengths 28 cm,
4 cm and 5 cm. If the answer is A cm2 then
write the value of A.
PLEASE HELP ME OMG X
Answer:
Answer: 544
Step-by-step explanation:
The Surface Area of a Cuboid
Given a cuboid (rectangular prism) of dimensions x,y, and z, the surface area is calculated as follows:
[tex]S=2(xy+yz+xz)[/tex]
The dimensions of a given cuboid are x=28 cm, y=4 cm, z=5 cm, thus:
[tex]S=2(28*4 + 4*5+ 28*5)[/tex]
[tex]S= 2*272 = 544[/tex]
The surface area is [tex]544 cm^2[/tex]

10. The sum of two numbers is 102. One number is three less than twice the other.
What are the two numbers?
Answer:
(2n -3) + n = 102
2n - 3 + n = 102
3n - 3 = 102
3n = 105
n = 35 (the first number)
SO...
The other number is (2 x 35) - 3 =
70 - 3 = 67 (the second number)
The numbers are 35 and 67.
35 + 67 = 102 CHECK!

y=-2/3x+1
how do you find the slope and y intercept
Answer:
The slope is -2/3 and the y intercept is 1
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2/3 x+1
The slope is -2/3 and the y intercept is 1
Casey wants to buy a gym membership. One gym has a $70 joining fee and cost $35 per month. Another Jim has no joining fee and cost $70 per month. when would Casey pay the same amount to be a member of either gym? How much would he pay?
Answer:
same amount at 2 months. he'd pay 140.
Step-by-step explanation:
35(month) +35(month) =70(joining fee). 70+70=140. that's two months at the first gym.
the second gym is also 140 for the two months because each month is $70. and 70+70=140

How does x = 0.7x + 24 equal 80?
Answer:
x=0.7x+24
We move all terms to the left:
x-(0.7x+24)=0
We get rid of parentheses
x-0.7x-24=0
We add all the numbers together, and all the variables
0.3x-24=0
We move all terms containing x to the left, all other terms to the right
0.3x=24
x=24/0.3
x=80
And that's how you get 80
Step-by-step explanation:
i hope this helps. :)
Answer: x = 80
Step-by-step explanation:
80 - 24 = 56
56 divided by 0.7 = 80
