What is the value of x? Enter your value as a decimal rounded to the nearest tenth,
Answers
Step-by-step explanation:
Use the Pythagorean Theorem ( [tex]a^{2}+b^{2} =c^{2}[/tex] )
The longest side is c = the hypotenuse, and a and b = the other sides of the triangle.
a = 4 First: [tex]4^{2}+x^{2}=8.5^{2}[/tex]
b = x Second: [tex]16+x^{2}=72.25[/tex]
c = 8.5 Third: [tex]x^{2}=56.25[/tex]
Fourth: [tex]x=\sqrt{56.25}[/tex]
Fifth: x = 7.5

What is the total area of each garden bed has a length of 4 feet Amelia
Answers
Answer:
48 ft^2.
Step-by-step explanation:
In this case, our formula is known as 3s^2 which can be written out as 3 x s x s or 3(s x s). S is the variable to represent our length and width because the formula for finding the area is l x w which can be written out as length x width. If the total area of each garden bed has a length of 4 feet, our equation would be 3(4 x 4) or 3 x 4 x 4 or 3(4)^2. 4 x 4 or 4^2 is 16. If we multiply 16 by 3, the answer would be 48. That is why the total area of each garden bed would be 48 ft^2.
The scale of map is 1cm : 70km. What is the actual distance between towns that are 5cm apart on the map

Write the equation of the line that is parallel to the line -3x+2y=10 and goes through the point (4,7).
Answers
Answer:
y=-3/2x+13
Step-by-step explanation:
Convert to slope-intercept form (y=mx+b):
-3x+2y=10
-3x-10+2y=0
-3x-10=-2y
-3/2x-5=y
y=-3/2x-5
Parallel lines have the same slope, so the slope of the equation will be m₁=m₂ where -3/2=-3/2
Solving for b, the y-intercept, we get:
y=-3/2x+b (Equation so far)
7=-3/2(4)+b [Plugging in (4,7)]
7=-12/2+b
7=-6+b
13=b
Therefore, the equation of the line that is parallel to the line -3x+2y=10 and goes through the point (4,7) is y=-3/2x+13
Suppose you invest money in two accounts. One of the accounts pays 4% interest annually, and
the other account pays 5% interest annually. You have $ 2000 more invested in the account paying
4% than in the account paying 5%. How much do you have invested in the account paying 4% if
you earn $ 670 interest in a year?
Answers
Answer:
$16,750
Step-by-step explanation:
It took a lot of plugging in and guessing
The formula used was 16750(1+.04)^1
That equaled 17420
17420-16750 is 670
