Answer:
ok, so she made 10 bracelets in 2.5 hours. 22-12= 10
2.5 ÷10= .25 hours per bracelet
an hour is 60 minutes, so .25 x60= 15 minutes per bracelet
write a quadratic equation with a double root of -5
Answer:
x^2 =5
Step-by-step explanation:
Answer:
x² + 10x + 25 = 0
Step-by-step explanation:
Given that x = - 5 is a root then (x + 5) is a factor
Since it is a double root then (x + 5)² so equation is
(x + 5)² = 0 ← expand factor using FOIL
x² + 10x + 25 = 0
(14,-1),(5,7) slope
Answer:
(-9, 8)
Step-by-step explanation:
(14, -1) >> (x1, y1)
(5, 7) >> (x2, y2)
(y2 - y1) 7 - (-1) = 8
----------- >>>
(x2 - x1) 5 - 14 = -9
x always goes first in a coordinate, so
(-9, 8)

A bike tire has a diameter of 35 inches. If the tire rotates 10 revolutions, how far did the bike travel?
Answer:
Distance travelled = 91.61 feet
Step-by-step explanation:
Given the following data;
Diameter, d = 35 inches
Number of revolutions = 10 Rev
To find the distance travelled by the bike;
First of all, we would determine the circumference of the bike's tire, which is circular in shape.
Circumference of circle = πd
Circumference of circle = 35π
Next, we multiply by the number of revolutions to get the distance travelled.
Distance travelled = 35π * 10
Distance travelled = 350π inches
But pie, π = 3.142
Distance travelled = 350 * 3.142
Distance travelled = 1099.7 inches.
In feet;
1 inches = 0.0833 feet
1099.7 inches = x feet
Cross-multiplying, we have;
x feet = 1099.7 * 0.0833
x feet = 91.61 feet
Distance travelled = 91.61 feet
Which equation represents a line which is parallel to x=0?
y=5
x=4
x=1/4y
x=−4y
Answer:Answer is A
Step-by-step explanation:
Correct option is
A
6x+2y=15
Given line is y=−3x+4
This is slope intercept form of a line where slope of line is −3.
Since, two lines are parallel When their slopes are equal.
Slope of line is 6x+2y=15
⇒2y=−6x+15
⇒y=−3x+
2
15
is equal to −3
Option A is correct.
A dilation maps (4, 6) to (2, 3). Under the same dilation, (-1, 3) would be mapped to _____. (-1/2, 3/2) (-3, 0) (-2, 6)
Answer:
(-1/2, 3/2).
Step-by-step explanation:
A dilation maps (4, 6) to (2, 3).
4/2 = 2, 6/3 = 2
It means that each coordinate is divided by 2.
(-1, 3) would be mapped to
Dividing by 2: (-1/2, 3/2) is the correct answer

At the end of a snow storm, Gavin saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 0.5 inches per hour
Answer: 20 hr
Step-by-step explanation:
Given
The depth of accumulated snow is [tex]d=10\ in.[/tex]
Snow is melting at the rate of [tex]r=0.5\ \text{in. per hour}[/tex]
Time taken for complete melting of snow is
[tex]\Rightarrow t=\frac{d}{r}\\\\\Rightarrow t=\frac{10}{0.5}=20\ hr[/tex]

HURRY! Which expression represents the difference quotient of the function f(x) = 13-5x/4 for all nonzero values of h?
A. 1/4
B. h/4
C. -5/4
D. -5h/4
13-5x/4
13-5 dividendo 4
13-5/4
47-5/4
1/4
The expression represents the difference quotient of the function f(x) = 13-5x/4 for all nonzero values of h is ( 1 / 4). The correct option is A.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given function is f(x) = 13-5x/4. The value of the expression will be calculated as below:-
E = 13-5x/4
Put the value of x equal to 1.
E = 13-5/4
E = 47-5/4
E = 1/4
Therefore, the value of the expression is (1/4).
