Please help me how do I solve and draw the problem ?
Answer:
Side of the rhombus is 12 cm. Let d1 = 2x cm , so d2 = 2x+6 cm
Now, 12^2 = x^2 + (x+3)^2 = 2x^2 + 6x+9 = 144, or
2x^2 + 6x-135=0, or
x^2+3x-67.5 = 0
x1 = [-3 +(9+270)^0.5]/2
= [-3+279^0.5]/2
= [-3+16.70329309]/2 = 6.851646544 cm [x2 will be negative and so inadmissible]
So d1 = 2x6.851646544 = 13.70329309 cm and d2 = 19.70329309 cm.
So the area of the rhombus is 13.70329309x19.70329309/2 = 135 sq cm.

1.1 = -8.5 + 6x what is x
Answer: x=1.6
Step-by-step explanation:
1.1=-8.5+6x
+8.5 +8.5 (add 8.5 on each side)
9.9=6x
Divide by 6 on each side to leave the x by itself
x=1.6
Answer:
x= 1.6
Step-by-step explanation:.
1.1=−8.5+6x
Step 1: Simplify both sides of the equation.
1.1=6x−8.5
Step 2: Flip the equation.
6x−8.5=1.1
Step 3: Add 8.5 to both sides.
6x−8.5+8.5=1.1+8.5
6x=9.6
Step 4: Divide both sides by 6.
6x /6 = 9.6/ 6
x=1.6
Answer:

What is 212,514 +396,705 estimated
Answer:
Estimate = 600,000
Step-by-step explanation:
An estimate can be defined as a rough calculation of a numerical value, usually the upper limitation.
Given the following numerical values;
212,514
396,705
To add the two values together, we would first of all determine the estimate.
Estimate of 212,514 = 200,000
Estimate of 396,705 = 400,000
Adding the two values;
200,000 + 400,000 = 600,000.
Actual addition of the values would have given;
212,514 + 396,705 = 609,219.
Therefore, 600,000 is an estimated value of 609,219.
Solve the equation in two different ways. Choose one method of solving in detail 5x+7(x+1) = 5x - 21
Answer:
METHOD 1:
5x+7(x+1)=5x-21
5x+7x+7=5x-21
12x+7=5x-21
12x-5x=-21-7
7x=-28
x=28/7
x=4
METHOD 2:
5x+7(x+1)=5x-21
5x+7(x+1)=5x-21-5x
7(x+1)=-21
7x+7=-21
7x=-28
x=4
Step-by-step explanation:
METHOD 1:
5x+7(x+1)=5x-21
5x+7x+7=5x-21
12x+7=5x-21
12x-5x=-21-7
7x=-28
x=28/7
x=4
METHOD 2:
5x+7(x+1)=5x-21
5x+7(x+1)=5x-21-5x
7(x+1)=-21
7x+7=-21
7x=-28
x=4
The population of weights for men attending a local health club is normally distributed with a mean of 172-lbs and a standard deviation of 27-lbs. An elevator in the health club is limited to 34 occupants, but it will be overloaded if the total weight is in excess of 6222-lbs. Assume that there are 34 men in the elevator. What is the average weight beyond which the elevator would be considered overloaded
Answer:
The average weight beyond which the elevator would be considered overloaded is 183 lbs.
Step-by-step explanation:
Weight in excess of 6222 lbs means that the elevator is overload.
With 34 men:
Average weight greater than:
6222/34 = 183 lbs
The average weight beyond which the elevator would be considered overloaded is 183 lbs.

Which number is a reasonable estimate for 39x24?
Answer:
800
Step-by-step explanation:
I rounded 39 to 40 and 24 to 20 to get numbers that are eadult multiplied
then we can do 40*20 which is 800 using mental math
hope this helps <3
Answer:
1000
Step-by-step explanation:
4*2 = 8
40 * 20 = 800
4*5 = 20
40* 5 = 200
40 * 20 + 40 * 5 = 800 + 200 = 1000
40 * 25 = 1000

three shapes. three areas to find. three areas to add together to find the whole area. gotcha.
Step-by-step explanation:
smaller rectanglelarger rectangleright trianglesmaller rectangle:
length is 7 cm and width is 4 cm, so the area is 28 square cm
larger rectangle:width is 4 cm and length is 10 cm, so the area is 40 square cm
Because the weird shape's bottom length was 13 cm. There are 3 cm and 7 cm on the top length(s) of the weird shape, next to each other. Looking at the dash lines, when adding 3 cm and 7 cm together, the larger rectangle's length is 10 cm.
right triangle:base is 3 cm and height is 8 cm, so the area is (3x8)/2 = 24/2 = 12 square cm
With knowledge from figuring out the larger rectangle's length being 10 cm and the weird shape's bottom length being 13 cm, we know the right triangle's base is 3 cm. (13 cm - 10 cm = 3 cm for the base of the right triangle).
Due to adding 4 cm and 4 cm of weird shape's width, which is also a right triangle's height.
weird shape's area from adding three shapes' areas:28 + 40 + 12
= 80 square cm (ANSWER)
