Answer:
1.8 miles
Step-by-step explanation:
In the first half hour, Sandra hikes 9/10 = 0.9 miles. She hikes that distance again in the second half-hour. After an hour, Sandra has hiked ...
2 × 0.9 miles = 1.8 miles
__
If you like, you can consider it a "unit rate" problem. To find miles per hour, divide miles by hours:
(9/10 mi)/(1/2 h) = (9/10)(2/1) mi/h = 9/5 mi/h = 1.8 mi/h
Sandra hikes 9/5 or 1.8 miles in an hour.
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.

No Solutions
Step-by-step explanation:
If you simplify the equation, you would get 30x + 30 = 30x + 40, which if you subtract 30x, you would get 30 = 40, which means that there are no solutions, because no amount for x would balance this equation.

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.

Mr. Smith's wife works at an animal hospital. There is a equivalent fraction relationship between the number of dogs and cats in the kennels. If there are 20 cats in the kennels, how many dogs?
Answer:
There are 10 dogs in the kennels
Step-by-step explanation:
The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.
Which means, if [tex]n_d[/tex] the number of dods and [tex]n_c[/tex] is the number of cats, then,
[tex]\frac {n_d}{n_c}=\frac{1}{2}\cdots(i)[/tex]
Given that there are 20 cats, so [tex]n_c=20.[/tex]
Now, from equation (i) we have,
[tex]\frac {n_d}{20}=\frac{1}{2}[/tex]
[tex]\Rightarrow n_d=\frac{1}{2}\times 20[/tex]
[tex]\Rightarrow n_d= 10[/tex].
Hence, there are 10 dogs in the kennels.

Answer:
(4, -1)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
x - 2y = 6
y = 11 - 3x
Step 2: Rewrite systems
Define: x - 2y = 6Add 2y on both sides: x = 2y + 6x = 2y + 6
y = 11 - 3x
Step 3: Solve for y
Substitute in x: y = 11 - 3(2y + 6)Distribute -3: y = 11 - 6y - 18Combine like terms: y = -6y - 7Add 6y on both sides: 7y = -7Divide 7 on both sides: y = -1Step 4: Solve for x
Define: x - 2y = 6Substitute in y: x - 2(-1) = 6Multiply: x + 2 = 6Subtract 2 on both sides: x = 4Answer:
x=4 y=-1

What is the probability of getting a 2 or
a 4?
Answer:
1/3 or 3.33
Step-by-step explanation:
There are 6 sides to dice, and to land on one side is a 1/6th of a chance. to land on 2 possible sides, you do 1/6+1/6 which equals 2/6 which is equivalent to 1/3 or 3.33 as a decimal.
I hope this helps and good luck!
Answer:
1/3 or 3.3333333333333333333 repeating

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

Ricky and Sam each bought a remote control car for $80. A few months later they both sold it. Ricky sold his car for 25% less than the original price and Sam sold his car for 30% less than the original price. How much more did Ricky get than Sam?
Answer:
4
Step-by-step explanation:
25/100 x 80/1 = 20/1
80 - 20 = 60
30/100 x 80/1 = 24/1
80 - 24 = 56
60-56=4
