Answer:
125 meters squared
Step-by-step explanation:
Surface area of initial pyramid:
A= 10²+4*1/2*10*15= 400 m²Surface area of extended pyramid:
A= 10*15+2*1/2*15*15+2*1/2*10*15= 525 m²The difference is:
525- 400= 125 m²Answer:
First pyramid is = 400 meters squared
A= 10²+4*1/2*10*15= 400 m²
second pyramid = 675 meters squared
A= 10*15+2*1/2*15*15+2*1/2*10*15= 525 m²
Subtract the two =
525- 400= 125 m²

What is the point-slope form of a line with slope -3 that contains the point (10,-1)?
A. y + 1 = 3(x+10)
B. y + 1 = 3(x-10)
C. y + 1 =-3(x-10)
D. x + 1 = -3(y -10)
Answer:
the point slope form is
y + 1= -3(x - 10)
solution is c
Estimate the solution to the system of equations.
You can use the interactive graph below to find the solution.
2x + 3y = 6
- 4x + 3y = 12
Answer:
D. [tex]x=-1, y=2\frac{2}{3}[/tex]
Step-by-step explanation:
Solving for x:
2x+3y=6
Subtract 3y from both sides
2x= -3y+6
Subtract 6 from both sides
2x-6= -3y
-4x+3y=12
Subtract 3y from both sides
-4x= -3y+12
Subtract 12 from both sides
-4x-12= -3y
Combine equations:
-4x-12=2x-6
Add 4x to both sides
-12=6x-6
Add 6 to both sides
-6=6x
6x= -6
Divide both sides by 6
x= -1
Solving for y:
2x+3y=6
Subtract 3y from both sides
2x= -3y+6
-3y+6=2x
Multiply both sides by -1
3y-6= -2x
Multiply both sides by 2
6y-12= -4x
-4x+3y=12
Subtract 3y from both sides
-4x= -3y+12
-3y+12= -4x
Combine equations:
6y-12= -3y+12
Add 3y to both sides
9y-12=12
Add 12 to both sides
9y=24
Divide both sides by 9

Which sets of side lengths represent Pythagorean triples? Check all that apply.
01, 2,5
6, 8, 14
08, 15, 17
10, 24, 26
15, 20, 30
28, 45, 53
Answer:
08, 15, 17
Step-by-step explanation:
Use the Pythagorean theorem.
Where the sum of both legs squared is equal to the hypotenuse squared.
8² + 15² = 17²
64 + 225 = 17²
289 = 17²
289 = 289
The side lengths that represent Pythagorean triplets are 08, 15, 17.

Penny earns $580 more than half of Karen´s salary. If p represents Penny´s salary, write an expression that represents the amount of money Karen earns in relation to Penny.
Answer:
[tex]\frac{p}{2} + $580[/tex]
Step-by-step explanation:
p = Penny's salary
Karen's salary = $580 more than half of p
We can use the fraction [tex]\frac{p}{2}[/tex] to represent half of p.
Since Karen's salary is $580 more, her salary is $580 + [tex]\frac{p}{2}[/tex] .

2x − 5y = 16
3x + 2y = 5
can you also explain how you did it. Thanks :)
Answer:
x=3
y=-2
Step-by-step explanation:
2x - 5y = 16
3x + 2y = 5
Solve for x in the first equation.
2x - 5y = 16
2x = 16 + 5y
x = (16 + 5y)/2
x = 8 + 5/2y
Put x as 8 + 5/2y in the second equation and solve for y.
3(8+5/2y) + 2y = 5
24+15/2y + 2y = 5
24 + 19/2y = 5
19/2y = 5-24
19/2y = -19
y = -2
Put y as -2 in the first equation and solve for x.
2x - 5(-2) = 16
2x +10 = 16
2x = 16-10
2x = 6
x = 3

A Canadian dollar is worth about $0.85 in
Answer:
B) $412 U.S Dollars
Step-by-step explanation:
350 divided by 0.85 = 411.7 and then round
Answer:
d. $298 U.S. dollars
Step-by-step explanation:
$1 Can = $0.85 US
Divide both sides of the equation by $1 Can
1 = ($0.85 US)/($1 Can)
$350 Can * ($0.85 US)/($1 Can) = $297.50 US
Answer: d. $298 U.S. dollars

Given that ABCD is a rhombus, what is the value of x?
Answer:
B
Step-by-step explanation:
A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:
[tex](4x-25)+x=90[/tex]
[tex]4x-25+x=90[/tex] Take out the parentheses
[tex]5x-25=90[/tex] Combine like terms
[tex]5x=115[/tex] Add 25 to both sides so as to isolate the variable
[tex]x=23[/tex] Divide both sides by 5
Answer:
the answer is b or 23

Convert the decimal 0.83 to a fraction, and classify it as either rational or irrational
Answer:
83/100, rational
Step-by-step explanation:
A rational number is a number that ends. Even if it has decimals, the decimals have to end. 0.83 is a rational number because it doesn't continually go on.
To write it into a fraction, the easiest way is to take it out of a hundred, like a percentage.
Answer:
83/100
Rational.
Step-by-step explanation:
0.83 can be converted to a fraction.
83/100
The fraction cannot be simplified further.
It is rational because it can be written in the form p/q, where p and q are whole numbers.

Answer: C, It stays the same.
Step-by-step explanation: If you simplify the ratio (the fraction) by canceling the t's, you get 2/1 or 2:1. This means that no matter the value of the variable t, the value of the expression will stay the same.

Write an equation of a line that passes through the point (3, 2) and is parallel to the line y = 3x - 4. (5 po
y = 3x + 7
y = 3x - 7
y =
x + 2
O y = fx-2
Answer:
y = 3x-7
Step-by-step explanation:
Lines that are parallel have the same slopes.
y = 3x-4 ---> y=mx+b (slope = m=3)
point-slope formula for a line: y - y1 = m(x-x1)
slope=m=3
(3,2)----> (x1,y1)
y - 2 = 3(x-3)
y - 2 = 3x-9
y = 3x-7
