Answer: It will take 10 weeks! :)
Step-by-step explanation:
So let's look at this together.
The question states that they raise 90$ per week.
There's two ways you can do this
You can multiply,
Think, what times 90 will equal 900? The answer is 10!
90 x 10= 900!
(if you need help with multiplication, let me know)
Or you can divide.
900/90=10!
(if you need help with division, let me know)
So it would take, in total, 10 weeks to raise 900 dollars.
Write the equation of the line through the given point. Use slope-intercept form.
3
(-4,6); perpendicular to y = -
2x+3
Write an equation for the line in slope-intercept form.
(Simplify your answer. Use integers or fractions for any numbers in the equation)
Answer:
2y=x+16
Step-by-step explanation:
condition for a perpendicular line to the previous line is that the gradient M1=-1/M2. looking at the question above the equation of the line given y=-2x+3 that is the first M1=-2. so to get the gradient M2 of the line perpendicular, then M2=-1/-2=1/2. so M2=1/2. so the equation of the new line is y=1/2x+C. so we can find C. since the line passes through (-4,6). when x=-4, y=6, 6=1/2(-4)+C..C=6+2=8. so the equation of the new line y=1/2x+8 we can multiply via 2. so we have 2y=x+16
the equation is 2y=x+16

Answer:
[tex]\boxed{\bold{\huge{\boxed{Area\ of\ Trapezium = 150\ cm\²}}}}[/tex]
Step-by-step explanation:
Using Pythagorean Theorem first to find EC
[tex]\sf CB^2 = EB^2+EC^2\\Where \ CB = 13 \ and \ EB = 5 \\13^2 = 5^2 + EC^2 \\169 - 25 = EC^2 \\EC^2 = 144\\Taking \ sqrt \ on \ both \ sides\\EC = 12 \ cm[/tex]
Given that:
AE = EC
AE = 12 cm
Now,
AB = AE + EB
AB = 12 + 5
AB = 17 cm
ABCD is a trapezoid / trapezium
So,
Area of Trapezium = [tex]\sf \frac{AB+DC}{2} (EC)[/tex]
Where AB = 17 , DC = 8 and EC = 12
Area of Trapezium = [tex]\sf \frac{17+8}{2} ( 12)[/tex]
Area of Trapezium = (25)(6)
Area of Trapezium = 150 cm²

Two forces are given by j = (-2,1] and K = (-5,3), in
Newtons. What is the magnitude of j+k ?
Answer:
[tex]\sqrt{65}[/tex]
Step-by-step explanation:
The magnitude of a vector < x, y > is calculated as
| < x, y > | = [tex]\sqrt{x^2+y^2}[/tex]
Thus
j + k = < - 2, 1 > + < - 5, 3 > = < - 2 - 5, 1 + 3 > = < - 7, 4 >
Then
| < - 7, 4 > | = [tex]\sqrt{(-7)^2+4^2}[/tex] = [tex]\sqrt{49+16}[/tex] = [tex]\sqrt{65}[/tex]

What is the value of 3^5 times 3^3 divided by 3^4
Answer:
3^4
Step-by-step explanation:
One of the laws of exponents is that when you are multiplying exponents with the same base, then you add their powers. So,
3^5 x 3^3 = 3^8
Another law is when dividing exponents with the same base, you can subtract the powers. So,
3^8/3^4 = 3^4

D is between C and E, CD = x 2 , CE = 32-2x, and DE = 12x. Find CD, DE, and CE.
Answer:
CD = 4DE = 24CE = 28Step-by-step explanation:
The segment addition theorem tells you ...
CD +DE = CE
x^2 +12x = 32 -2x
Subtract the right side to put this in standard form.
x^2 +14x -32 = 0
(x +16)(x -2) = 0
x = -16 or 2
In order for DE to have a positive length, we must have x > 0. So ...
CD = x^2 = 2^2 = 4
DE = 12x = 12(2) = 24
CE = 32 -2x = 32 -2(2) = 28

ugh no body knows this? Suppose a square garden represented by 16x2 ft2. a. What is the length of each side? b. What is the perimeter of the garden? c. If each side was increased by 5 feet what would be the new perimeter?
Answer:
A. [tex]4x[/tex]
B. [tex]16x[/tex]
C. [tex]16x+20[/tex]
Step-by-step explanation:
A square's area will be the length of each side squared (that's why it's called squared).
Since we know the area, we can find the square root of [tex]16x^2[/tex] to find the length of each side.
We know that [tex]4^2 = 16[/tex] and [tex]x^2 = x^2[/tex], so [tex]4x\cdot 4x[/tex] should be equal to [tex]16x^2[/tex].
This means the side length is [tex]4x[/tex].
The perimeter of a square will be 4 times it's side length. We know the side length, so the perimeter is [tex]4x \cdot 4 = 16x[/tex].
If we added 5 to the length of each side, the new side length would be [tex]4x + 5[/tex]. Again, the perimeter is 4 times the side length so the perimeter would be [tex]4(4x + 5) = 16x + 20[/tex].

Given the function f(x)=2x-4 find x if f(x)=10
Answer:
7
Step-by-step explanation:
Since f(x)=10 is equivalent to f(x)=2x-4, make these equations equivalent. Add 4 to both sides, and simplify to get 2x=14. Divide both sides by 2 to get 7 as your answer.
Answer:
x = 7
Step-by-step explanation:
Given
f(x) = 2x - 4 and f(x) = 10, then equating gives
2x - 4 = 10 ( add 4 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
Write an equation for a line that is parallel to 2x+5y=15 and passes through the point (-10, 3)
Answer:
The equation of the line is,
[tex]y = - \frac{2}{5} x - 1[/tex]
Step-by-step explanation:
First, you have to write it in a form of y = mx + b :
[tex]2x + 5y = 15[/tex]
[tex]5y = 15 - 2x[/tex]
[tex]y = 3 - \frac{2}{5} x[/tex]
[tex]y = - \frac{2}{3} x + 5[/tex]
When both lines are parallel to each other, they will have to same gradient value. So the equation of the line is y = (-2/5)x + b. Next, you have to find the value of b by substutituting (-10,3) into the equation :
[tex]y = - \frac{ 2}{5}x + b [/tex]
[tex]let \: x = - 10,y = 3[/tex]
[tex]3 = - \frac{2}{5} ( - 10) + b[/tex]
[tex]3 = 4 + b[/tex]
[tex]3 - 4 = b[/tex]
[tex]b = - 1[/tex]
Answer:
the equation of a parallel line is : y=-2/5 x -1
Step-by-step explanation:
2x+5y=15
put the equation in the form of y=mx+b
2x+5y=15
5y=15-2x
y=15/5-2/5 x
y=-2/5 x+3
parallel lines has the same slope : m=-2/5
passes through point (-10,3) find b
y=-2/5 x +b
3=-2/5(-10)+b
3=20/5 +b
3=4+b
b=3-4
b=-1
the equation of a parallel line is : y=-2/5 x -1

An angle measures 50° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
20° and 70°
Step-by-step explanation:
Complementary angles sum up to 90°.
The angle = x
Its complement = x + 50
x + x + 50 = 90
2x = 40
x° = 20°
20+50=70
Answer: 70° and 20°
Step-by-step explanation:
Complementary angles add up to 90 degrees and we now that one angles measure is 50 degrees less than the other. So we can represent it by the expression x = y -50 where x and y are the two angles. We don't the value of y so it will be just y .
Now we know that if we add them,they will equation 90 degrees so we can represent it by the equation,
y + y-50 = 90 Now solve for y
2y - 50 = 90
+50 +50
2y = 140
y = 70
Now we know one angles is 70 degrees and the other is 50 less than it so the other angle will be 70 - 50 = 20
