Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²

for the pairs below put each question in slope intercept form and whether the graphs of the line will be identical, parallel, or intersecting, Also determine how many solutions the system of equations will have
Answers
Both equations are now y = 3x + 2. So they are identical, and therefore have infinite solutions since solution means how many times do these lines meet/overlap.
4: rewrite left-right and the equations are now:
y = -x
y = -x -2
Same slope but different intercept (b value), so they are parallel and NEVER meet (NO SOLUTIONS)
5. Rearrange:
y = -x + 4
y = x + 4
So they have different SLOPES in this example (m value). This means they are not parallel or identical, so they can only cross once (one solution)
6: rearrange both
y = 3x - 1
y = 3x + 1
Same slope (m=3), different intercepts (b= 1 and -1). Same slope means parallel, different b means different intercepts so they are NOT identical. Since parallel lines can not cross, there are no solutions
7: y = 2x + 4
y = 2x - 4
Same slope (m=2), different b values (y-intercepts are 4 and -4), so parallel but not identical, no solution

Slope= -65
y intercept = 1000
and what it's saying is that we travel at a speed of 65 units an hour and we start 1000 miles away
Step-by-step explanation:
Just graph these points which you can get by plugging in the numbers
1000-65= 935
(1,935)
1000-65*2=870
(2,870)
1000-65*3= 805
(3,805)
1000-65*4=740
(4,740)
1000-65*5= 675
(5,675)
B:
y= mx+b where m is the slope and B is the y intercept
we can re write the equation as follows
-65x+1000
It's pretty clear that -65 is the slope and 1000 is the y intercept

Given:
Point V is located at (-5,3) on the coordinate plane.
It is reflected over the y-axis to create point V'.
Point V' is then reflected over the x-axis to create point V''.
To find:
The location of point V''.
Solution:
We have,
Point V= (-5,3)
If point V reflected over the y-axis, then
[tex](x,y)\to (-x,y)[/tex]
[tex]V(-5,3)\to V'(5,3)[/tex]
If point V' reflected over the x-axis, then
[tex](x,y)\to (x,-y)[/tex]

Therefore, the ordered pair (5,-3) describes the location of V''.

Answer:
[tex]\boxed{\textsf{ The factorised form is \textbf{(4x+1)(3x+1)}.}}[/tex]
Step-by-step explanation:
A quadratic polynomial is given to us and we need to find its factorised form . The given quadratic polynomial is ,
[tex]\sf\implies p(x)= 12x^2+7x+1[/tex]
And this equation is similar to the equation in ax² + bx + c form . So in order to factorise it .
Step 1: Multiply the coefficient of x² with the constant term .
Here the coefficient of x² is 12 and the constant term is 1 . So on multiplying them we get 12*1= 12 .
Step 2: Look out for the possible factors of the number .
Here the obtained number is 12 . So the possible factors of 12 is
1 *12-1*-122*6-2*-64*3-4*-3Step3: Choose the factor whose sum is equal to the coefficient of the middle term .
Here we can see that the middle term is 7 . And the sum of 4 and 3 is equal to 7 . Hence here we will break 7x as 4x + 3x .
Step 4: After proper arrangements take out the common term and then factorise.
After suitable rearrangment we get ,
[tex]\sf\implies p(x)= 12x^2+4x+3x+1 \\\\\sf\implies p(x)= 4x(3x+1)+1(3x+1) \\\\\implies\boxed{\red{\sf p(x)= (4x+1)(3x+1)}}[/tex]

This is well within the mass uncertainty of 0.01% (6×1020 kg), so the estimated value of Earth's mass is unaffected by this factor. Mass loss is due to atmospheric escape of gases. About 95,000 tons of hydrogen per year (3 kg/s) and 1,600 tons of helium per year are lost through atmospheric escape.

Answer:
For each draw, the chances of getting a blue marble are 3 of 7; the chances of getting a red are 4 of 7.
The chances of drawing a blue on both draws is (3/7)^2 or 9/49, and the chances of getting red on both draws is (4/7)^2 or 16/49. But there are other possible outcomes which have to be considered to come to the correct answer.
There are 4 possible outcomes, as follows (although the chances of these outcomes are different):
Comb Chances
RR …….. 16/49
RB …….. 12/49
BR …….. 12/49
BB ……… 9/49
total …….. 49/49
So we can say that the chances of drawing red marbles on each draw are 16/49, and the chances of drawing blue ones on each draw are 9/49. But what about the chances of drawing either both red OR both blue?
I believe we can simply add the 2 probabilities together to come up with a probability of

The Percentage of the down payment is given as:
Down payment/Cost of the house × 100
Down payment = $25,000
Cost of the house = $125,000
$25,000/$125,000 × 100
= 20%
