Given that:
Edge of the square pyramid = 14 unit Slant height of the square pyramid = 25 unitTo Find:
The height of the square pyramid.We know that:
In pythagoras theorem.
H² = P² + B²Where,
H = Hypotenuse = 25 unitP = Height = Let xB = Base = 14/2 = 7 unitFinding the height of the square pyramid:
⇒ H² = P² + B²
⇒ (25)² = x² + (7)²
⇒ 625 = x² + 49
⇒ x² = 625 - 49
⇒ x² = 576
⇒ x = √576
⇒ x = 24
Hence,
The height of the square pyramid is 24 unit

Calculate the volume of the following cylinders.
Radius = 10 cm
Height = 20 cm
Answers
Answer:
2000pi
Step-by-step explanation:
V of a cylinder = Area of the base × height
Area of a circle = pi × r^2
A = pi × (10)^2 = 100pi
V = 100pi × 20 = 2000pi
Eighteen students passed the Science Test. If 18 students is 72% of the total number of students in the class, how many students are in the class?
Answers
Answer:
There are 25 students in the class.
Step-by-step explanation:
Let the total number of students in the class= x
No. of students who passed the test = 18 = 72% of x = 72x/100
Therefore, 72x/100=18
=72x=18*100=1800
=x=1800/72= 25 students.
Hence, total number of students in the class= 25 students

Which system of equations has infinitely many solutions?
A

4x−2y=8
B
4x−2y=8
−4x+2y=−8
C
4x+2y=8
4x+2y=10
D
4x+2y=8
−4x−2y=−10
Answers
Answer: B.
[tex]4x - 2y = 8\\-4x + 2y = -8[/tex]
Step-by-step explanation:
Let's solve your system by elimination.
4x−2y=8;−2x+2y=6
Add these equations to eliminate y:
4x-2y=8
-2x+2y=6
2x=14
Substitute 7 for x in 4x−2y=8:
(4)(7)−2y=8
−2y+28=8 (Simplify both sides of the equation)
−2y+28+−28=8+−28 (Add -28 to both sides)
−2y=−20
−2y/−2=−20/−2 (Divide both sides by -2)
y=10

Answers
The -1/2x is the slope or the rise/rub
The -3 is the y-intercept
So start by placing the y-intercept (0,-3), then from there place the slope (-1/2), since the slope is negative instead of going up one and two to the left you are going to go down one and two to the right, then place a point and repeat. After repeating 2-3 times you should be able to connect the points in order to make a line. If you have any questions let me know!

What type of triangle is this triangle?
acute isosceles
obtuse isosceles
Right isosceles
acute scalene
Answers
it has 2 congruent sizes, no right angles and seems two big to be acute
Answer:
obtuse isosceles
Step-by-step explanation:
An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.

64 pretzels = 16 oz
16 pretzels = 4 oz
1 pretzel = .25 oz
4 pretzels = 1 oz
Step-by-step explanation:
If you know that 64 equals 16 ounces than you can divide 64 by 16 to get 4. This means that one ounce equals four pretzels. Then you can multiply 1 oz by 4 and 4 pretzels by 4 to get 16 pretzels that equal 4 oz. If 4 pretzels equals 1 oz then 1 pretzel equals 1 oz divided by 4.

(x + 5)**2 + (y + 2)**2 = 25
Step-by-step explanation:
We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. The graph shows the center at (-5, -2), and the radius of 5. So plugging this in
(x - -5)**2 + (y - - 2)**2 = 5**2
(x + 5)**2 + (y + 2)**2 = 25

Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?
Answers
Answer:
40 waves
Step-by-step explanation:
Prob (Mark catches waves) = Times waves caught / Total waves = 8 / 20 = 4 / 5 = 20%
Predicted waves out of 50 , caught = 4 / 5 or 20% of 50 = (4 / 5) x 50 = 40
Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.Find the determinant:

(a) Sketch the roof of the turret. Label all lengths, using x as the unknown.
(b) What is the slant height of the roof? Answer:
Answers
Answer:
Solution given:
base=diameter [d]=30m
radius [r]=d/2=15m
height [H]=8m
slant height [l]=xm
we have
∆ ABC is a right angled triangle
base[b]=r
perpendicular [p]=H
hypotenuse [h]=x
by using Pythagoras law
h²=p²+b²
x²=H²+r²
x²=8²+15²
x=√289
x=17m
the slant height of the roof is 17m.
