Answer:
length is 10, width is 7
Step-by-step explanation:
Area of a rectangle = length * width = lw
Area is known to be 70
length = twice width - 4 = 2w-4 = l
width=w
so A = lw = (2w-4)w = 70
(2w-4)w=70
2w^2-4w=70
2w^2-4w-70=0, divide by 2
w^2 - 2w - 35 = 0, not sure how your class solves these, I see visually
(w-7)(w+5)=0
w=7 or w=-5, -5 makes no sense in the real world (negative length), so w=7
l = 2w-4 = 2(7)-4 = 14-4 = 10

Answer:
2.4 or [tex]\frac{12}{5}[/tex]
Step-by-step explanation:
In the divisor (the second fraction) we flip the numerator and the denominator. This is known as the reciprocal and basically it means the reverse of the fraction. When we find the reciprocal, we also have to change the division sign to a multiplication sign.
Once you've flipped the second fraction and changed the symbol from divide to multiply, we can multiply the numerators together and the denominators together and we have our solution:
[tex]\frac{12}{5}[/tex]

whats a reasonable estimate for 529 divided by 23 ( explain your anwser )
Step-by-step explanation:
First you divide 529 and 23. You can divide 5w9 by 23 in a fraction like this 529/23 on to Desmos scientific calculator or just 529÷23 on a calculator. If it is a decimal, round it up if the tenth, hundredth, or thousandth is 5, 6, 7, 8, 9 or round down if the number is 4, 3, 2, and 1. The answer to 529÷23 is 23. And if you estimate it, it'll be 20. The next part may be a bit confusing but if you estimate 23, you'll get 25.
Then you estimate 529 and 23, you'll get 530 and 20. And if you divide them, you'll get 26.5. And if you estimate that, you'll get 27. So that means is 2 or 7 off from the estimated from the equation 529÷23. So that means the reasonable answer is probably 25 or 27.

Answer:
Step-by-step explanation:
A^2+B^C^2 ////////A^2=10, and B^2=X^2, and C^2=15
10^2 + X^2 =15^2
100 + X^2 = 225(15^2 = 225)
-100 -100
= square root x= square root (125)
your answer will be 125
The value of the missing side of this right triangle is 11.18 units and the number that belongs in the green box is 125.
What is Pythagoras theorem?Pythagoras theorem says that in a right angle triangle the square of hypotenuse side is equal to the sum of the square of other two legs of right angle triangle.
In the given image,
A right angle triangle is given.The length of the base is 15 units long.The length of the hypotenuse is 15 units long.Using the Pythagoras theorem, the value of x can be found out as,
[tex]x^2+10^2=15^2\\x^2=15^2-10^2\\x^2=225-100\\x^2=125\\x=\sqrt{125}\\x=11.18[/tex]
Thus, the value of the missing side of this right triangle is 11.18 units and the number that belongs in the green box is 125.

At the end of summer sale, an air conditioner that sold for $310 was discounted for 21%. What was the sale price?
Answer:
The sale price was $244.9.
Step-by-step explanation:
With the information provided, you can calculate the sale price by finding the 21% of the sale price and then, subtracting that amount from the sale price:
$310*21%=$65.1
$310-$65.1=$244.9
According to this, the answer is that the sale price was $244.9.

If you are looking for the value of x, use the Pythagorean Theorem.
x² = 58² - 40² = 1764
x = √1764 = 42
Answer: 42cm
Step-by-step explanation:
Using the formula
(Hypotenuse^2)= (Opposite^2) + (Adjacent^2)
Hypotenuse= 58cm
Opposite= 40cm
Adjacent= x
Therefore
(58^2)= (40^2) + (x^2)
3364= 1600 + x^2
3364-1600= x^2
1764= x^2
x= 1764^1/2
x= 42
Adjacent= 42cm

The green triangle is a dilation of the red triangle with a scale factor of s=13 and the center of dilation is at the point (4,2)
What are the coordinates of Point C'? C'(___,____)
What are the coordinates of Point A? A(____,_____)
Answers:
C ' (2, 5)A (16, 8)================================================================
Explanation:
I'm assuming you mean to say "scale factor of s = 1/3" since the green triangle is smaller than the red triangle.
Let's start at the point (4,2). This is the center of dilation. This fixed point does not move or change as you apply any dilation (as long as you keep this as the center of course). Every other point will move. For instance, the point (10,14) moves to (6,6) after applying the dilation.
----------------------
The x coordinate of the center point (4,2) is x = 4.
The x coordinate of the point (10,14) is x = 10.
Going from (4,2) to (10,14) will have us move a horizontal distance of 10-4 = 6 units.
Take 1/3 of this horizontal distance and we get (1/3)*6 = 2. This means that if we started at the center point (4,2) and move 2 units to the right, we will have the x coordinate to be x = 4+2 = 6, which matches up with the x coordinate of the point (6,6)
-------------------------
We'll do the same sort of thing with the y coordinates
The point (4,2) has the y coordinate y = 2
The point (10,14) has the y coordinate y = 14
The vertical distance between those points is 14-2 = 12 units
One third of this is (1/3)*12 = 4
If we started at (4,2) and moved up 4 units, then the y coordinate goes from y = 2 to y = 2+4 = 6. This also matches (6,6)
----------------------------
Hopefully by now you have a sense of how this all works. Let's use these tricks to find the location of point A.
The horizontal distance from (4,2) to (8,4) is 8-4 = 4 units. This triples to 4*3 = 12 units. We triple here because we're going in reverse of the process described in the previous two sections. If (8,4) and A swapped places, then we would take one third instead.
We'll use that 12 to count out 12 horizontal spaces from (4,2) to get to (16,2). I added 12 to the x coordinate of (4,2).
Repeat the process for the y values. The vertical distance from (4,2) to (8,4) is 2 units, which triples to 6. Add 6 onto the y coordinate of (16,2) and we arrive at (16, 8) which is the location of point A.
--------------------------------
Now let's find the location of point C'
The horizontal distance from (-2,11) to (4,2) is 6 units because |-2-4| = 6. Multiply this by 1/3 and we get (1/3)*6 = 2
To get to the location point C', we need to start at (4,2) and move to the left 2 units. That means (4,2) will move to (2,2) as a temporary location.
We apply the same idea for the y coordinates. The vertical distance from (4,2) to (-2,11) is 9 units. This leads to (1/3)*9 = 3 units being the vertical distance from (4,2) to the location of C'. We'll add 3 to the y coordinate of (2,2) to arrive at (2,5) which is the location of C'.
