Answer:
16.
solution:
perimeter = 64
4l = 64
l= 64/4
l=16
Answer:
Step-by-step explanation:
since it's a square we know the 4 sides are the same length.
64 / 4 = 16
so each side is 16.... now use pythagoras to solve for GE since we know the two legs of the triangle .. both 16
16^2 + 16^2 = GE^2
512 = GE^2
[tex]\sqrt{512}[/tex] = GE
22.627417 = GE
GE = 22.6 ( rounded to nearest 10th )

What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?
Answer:
A
Step-by-step explanation:
The density of the pyramid is approximately 0.57 grams per cubic centimeter.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
To find the density of the pyramid, we need to know its volume as well as its mass.
The volume of a pyramid is given by:
V = (1/3) × base area × height
The base of the pyramid is a rectangle with dimensions 5 cm by 7 cm, so its area is:
A = 5 cm × 7 cm
= 35 cm²
Using the formula for the volume of a pyramid, we have:
V = (1/3) × A× h
V = (1/3) × 35 cm² × 9 cm
V = 105 cm³
Now we can calculate the density:
density = mass / volume
Since the mass of the pyramid is given as 60 grams, we have:
density = 60 g / 105 cm³
To get the density in units of grams per cubic centimeter, we need to convert the units of mass and volume to grams and cubic centimeters, respectively:
density = (60 g / 1000) / (105 cm³ / 1000)
density = 0.57 g/cm³
Therefore, the density of the pyramid is approximately 0.57 grams per cubic centimeter.

How do you solve b^2=-3b
Answer:
b=0,-3
Step-by-step explanation:
b^2+3b=0
b(b+3)=0
b=0
b+3=0
b=-3
Answer:
b = 0 OR b = -3
Step-by-step explanation:
To start off with, we know that this must be a quadratic equation because there's a "^2".
Firstly, we have to bring everything over to one side of the equation. This means we have to add 3b to both sides, as we want the right-hand side to be 0.
b^2 = -3b
+3b +3b
b^2 + 3b = 0
Secondly, we have to factorise. We need to see what number goes into both "b^2" AND "3b".
That is "b".
b^2 + 3b = 0
factor out b
b(b + 3) = 0
Thirdly, we have to use the Null Factor Law to find out what b equals. The Null Factor Law states that if an equation equals 0, then one of the terms must either be 0, or the negative of the other number.
Hence, there are two answers.
b = 0
OR
b = -3

Parallelogram FIRE
Given:
[tex]fi = (3x - 5) \: cm[/tex]
[tex]ir = (2y - 7) \: cm[/tex]
[tex]re = (x + 7) \: cm[/tex]
[tex]ef = (y + 3) \: cm[/tex]
a. What is the value of x?
b. How long is FI?
c. What is the value of y?
d. How long is EF?
e. From your answers in b and d, what is the perimeter of parallelogram FIRE?
Answer:
See the solutions below
Step-by-step explanation:
First note that the opposite side of a parallelogram are equal, hence;
For Parallelogram FIRE
fi = re
ef = ir
Given
fi = (3x-5)cm
ir = (2y -7)cm
re = (x+7)cm
ef = (y+3)cm\
a) If fi = re, then;
3x - 5 = x+7
3x - x = 7+5
2x = 12
x = 12/2
x = 6
b) Since FI = 3x - 5
FI = 3(6) - 5
FI = 18 - 5
FI = 13cm
c) Also ef = ir
y+3 = 2y - 7
y - 2y = -7-3
-y = -10
y = 10
d) EF = y+3
EF = 10 +3
EF =13cm
e) Perimeter of the parallelogram = FI + IR + RE + EF
Perimeter of the parallelogram = 13cm + 13 + 13cm + 13cm
Perimeter of the parallelogram = 52cm

459,450,441, find the 37th term
Answer:
135
Step-by-step explanation:
So, our first term is 459.
Lets find what our change in terms is. To do this, lets subtract the frist term by the second:
459-450
This will get you 9.
Now that we know our change per term, lets find our 37th term.
All we need to do, is take our first term, and subtract it by our change in terms times the amount of terms.(Note that we already know are 1st term, so we are multiplying the change in terms by 36, not 37. )
So this is what we can use to solve for this:
459-(9x37)
This equals
135.
Hope this helps!
Step-by-step explanation:
first term = a = 459
common difference = d = 450 - 459 = -9
nth term = an
n = -9
an = a + (n-1)d
= 459 +(37-1)-9
= 459 + (36)-9
= 459 -324
= 135
37 th term = 135

Answer:

Step-by-step explanation:
Area of a rectangle = Length × Width
Area of a triangle = [tex]\frac{1}2[/tex] × Base × Height
3 sides are rectangles with the measurements of (9mm by 21mm)
So 3(9 × 21) = 567mm^2
6 sides are rectangles with the measurements of (9mm by 9mm)
So 6(9 × 9) = 486mm^2
1 side is a rectangle with the measurements of (9mm by 15mm)
So (9 × 15) = 135mm^2
2 sides are triangles with unknown, but equal bases.
To calculate the base, you subtract 9 from 21: 21 - 9 = 12mm
Therefore the base = 12mm
The other measurement can be found by looking to the left of the triangle (9mm from the side)
So 2([tex]\frac{1}2[/tex] × 12 × 9) = 108mm^2
Add the sides up:
567 + 486 + 135 + 108 = 1296 mm^2

30% of the scholars are working as stagehands. 35 scholars are actors and actresses. How many students in total are in the school play, acting and working behind the scene?
Answer:
There are 50 students in total in the school play, acting and working behind the scene.
Step-by-step explanation:
Since the statement indicates that 30% of the scholars are working as stagehands, you can subtract this from 100% that represents the total amount of student in the school play to find the percentage that are actors and actresses:
100%-30%=70%
Now, as you know that 70% of the students are actors and actresses and the statement indicates that they are 35, you can use a rule of three to find the amount of students that represent 100%:
70% → 35
100% → x
x=(100*35)/70
x=50
According to this, the answer is that there are 50 students in total in the school play, acting and working behind the scene.
