Grace wants to frame a square picture which has a area of
950 square inches.
How long is each side of the picture?
She has another square picture with an area of 1200 square inches.
How long is each side of this picture?
Answer:
First Picture: Length = 30.82in
Second Picture: Length = 34.64in
Step-by-step explanation:
Given
Picture 1:
Area = 950in²
Picture 2:
Area = 1200in²
Required
Determine the length of each pictures
From the question, we understand that both pictures are square in shape and the area is calculated as thus:
Area = Length²
For the first picture, substitute 950 for Area
This gives:
950 = Length²
Length ² = 950
Take square root of both sides
Length = √950
Length = 30.8220700148448822
Length = 30.82 (approximated)
Hence, the length of the first picture is 30.82in
For the second picture, substitute 1200 for Area
This gives:
1200 = Length²
Length² = 1200
Take square root of both sides
Length = √1200
Length = 34.6410161513775458
Length = 34.64 (approximated)
Hence, the length of the second picture is 34.64in

Convert 156% to a decimal
Answer:
1.56
Step-by-step explanation:
156 divided by 100
Answer:
1.56
Step-by-step explanation:
To convert a percentage to a decimal, you must divide the number by 100 because percentages are out of 100. 156 percent can also be written as 156/100 which you can simplify to 1.56.

A line passes through the point (-10, -2) and has a slope of
3/2
Write an equation in slope-intercept form for this line.
The equation of this line in slope intercept form is y = 1.5x + 13.
What is slope intercept form?The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis.
Equation of line: y = mx + c
where m is slope of line and c is the y intercept.
[tex]\frac{y+2}{x+10} = \frac{3}{2}\\ \\ 2(y+2) = 3(x+10)\\\\2y + 4 = 3x + 30\\\\2y = 3x + 26\\\\y = 1.5x + 13\\\\where\ slope = 1.5\ and\ y\ intercept\ is\ (0,13)[/tex].

a parabolic lamp is facing due east. The bulb (located at the focus) is 8 inches away from the vertex (located at the origin). the lamp has a diameter of 20 inches. Which is the depth of the dish?
9514 1404 393
Answer:
3 1/8 inches
Step-by-step explanation:
For focus-vertex distance p, the equation of the parabola can be written ...
y = x^2/(4p)
Here, we have p=8. We want to find the value of y when x=10 (the radius of the dish). That is ...
y = (10^2)/(4·8) = 100/32 = 3 1/8
The dish is 3 1/8 inches deep.

solve the equation 7- 14m = 2m - 5
Answer:
m = 6/7
Step-by-step explanation:
Rearrange the equation so that like terms are on either side
7 + 5 = 2m + 14m
12 = 14m
Divide both sides by 14 so that the variable is on its own
12/14 = m
m = 6/7
Decide whether this statement is always true, never true, or sometimes true, and explain why: In a quadratic equation of the form 0 = ax2 + bx + c, there will be two real solutions if a and c are of opposite signs
Answer:
Always true
Step-by-step explanation:
Here, we want to evaluate if the given statement is true
The discriminant D can be calculated using the formula;
b^2 - 4ac
if D is greater than 0, then we will have only real roots
In a case where a and c are of opposite signs;
then -4ac will always give a positive value which can be added to b^2
This positive value will ensure that D is greater than zero and hence we can have only real roots
So this assertion is always true if a and c are of opposite signs

Sharon drove 270 miles in 4.5 hours. If she drove at a constant rate, how fast was Sharon driving?
Answer:
Sharon was driving 60 miles per hour.
Step-by-step explanation:
To solve this you must divide both the amount of miles (270) and the amount of hours (4.5) by the amount of hours so that way you can see how many miles per hour you are going.
4.5 / 4.5 = 1
270 / 4.5 = 60
This means that Sharon was driving 60 miles per hour.

Answer:
37
Step-by-step explanation:
2-digit number: 10x + y
y = x + 4
20x + 2y = 10y + x + 1

Well the numbers are right, but not the order.
First the x-intercept is (-7,0) not (0,-7) ---- It's (x,y) though ---------
Second the y-intercept is (0,2) not (2,0)
You got them swapped but the numbers are correct anyway.
