Raheem's entire workout consisted of 15 minutes of warm-up exercises, 30 minutes of lifting weights,and 45 minutes on the treadmill.What is the ratio of the number of minutes he lifted weights to the total number of minutes of his entire workout? a. 1:1. b. 1:3. c.1:9. d.3:10
Answer:
b
Step-by-step explanation:
Time taken for the total workout = 15 + 30 + 45 = 90 minutes
Time taken for lifting weight : total time = 30 : 90
= 1 : 3

find the slope of the line
Answer:
The slope of the line is: 1
Step-by-step explanation:
Use the equation
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Use the two sets of points given to you to slve the equation.
Assign the points their variables:
x1 y1 x2 y2
(4, 4) (8, 8)
Insert the numbers into the equation:
[tex] \frac{8 - 4}{8 - 4} [/tex]
Simplify:
[tex] \frac{4}{4} = 1[/tex]
Find the value of x that makes lines u and v parallel, answer needed
Given:
u and v are parallel lines.
To find:
The value of x.
Solution:
If a transversal line intersect the two parallel lines, then
(1) Corresponding angles are congruent.
(2) Same sides interior angles are supplementary angles and their sum is 180 degrees.
15.
[tex]23x-2=90[/tex] (Corresponding angles)
[tex]23x=90+2[/tex]
[tex]x=\dfrac{92}{23}[/tex]
[tex]x=4[/tex]
Therefore, the value of x is 4.
16.
[tex](x+106)+(x+86)=180[/tex] (Same sided interior angles)
[tex]2x+192=180[/tex]
[tex]2x=180-192[/tex]
[tex]2x=-12[/tex]
Divide both sides by 2.
[tex]x=\dfrac{-12}{2}[/tex]
[tex]x=-6[/tex]
Therefore, the value of x is -6.
Y-1/4x=-1

Which trig ratio would you use to solve this?
O Sine
O Cosine

Answer:
Cosine
Step-by-step explanation:
sine = soh=o/h
cos=cah=a/h
tangent=toa=o/a
If you look at right triangle the slanted line is the hypothese. it will always be. so thats h. the adjacent is the line connected the the angle you are looking for. and opposite is the line thats away from the angle.

How do percents show the relationship between quantities?
Answer: Decide whether two quantities are in a proportional relationship, by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin . Use proportional relationships to solve multistep ratio and percent problems.

Consider the quadratic function, f(x)=-2x^2+12x+32=0. Select all statements that are true for the function. The value of the discriminant is -112. The value of the discriminant is 20. The value of the discriminant is 400. The function has 1 real solution. The function has 2 real solutions. The function has 2 complex solutions.
Answer:
Step-by-step explanation:
-2x² + 12x + 32 = 0
discriminant = 12² - 4(-2)(32) = 400
positive discriminant means there are two distinct real roots
x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]
= [-12 ± √400] / (-4)
= [-12 ± 20] /(-4)
= 8, -2

Which graph represents a geometric sequence? On a coordinate plane, 5 points are plotted. The points are (1, 1), (2, 3), (3, 5), (4, 7), (5, 9). On a coordinate plane, 4 points are plotted. The points are (1, 1), (2, 2), (3, 4), (4, 8). On a coordinate plane, 3 points are plotted. The points are (1, 2), (4, 4), (9, 6). On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 4), (3, 9).
Answer:
Graph B is the correct answer. Just in case it is not choice B for you, it's the graph with points (1,1), (2,2), (3,4), and (4,8) in that order. Sadly, the other guy is incorrect and you should not listen to him.
Step-by-step explanation:
The graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)
What is a geometric sequence?A geometric sequence is a sequence that has a common ratio
The common ratio of a geometric sequence is calculated as:
[tex]r = \frac{y_2}{y_1}[/tex]
Using the above rule, we have:
[tex]r = \frac{2}{1} = \frac 42 = \frac 84[/tex]
[tex]r =2 =2 =2[/tex]
The above represents option B, and it has a common ratio of 2
Hence, the graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)

Answer:
x=36
Step-by-step explanation:
2x+2x+x+4-2-2=180
Combine Like Terms
5x=180
Divide
x=36
Answer:
we know that if we add all of the angles it adds up to 180 degrees
Step-by-step explanation:
so 180=(x-2)+(2x+4)+(2x-2)
combine like terms
180=5x
divide by 5 to isolate variable
x=36
If you need to find for an angle apply the x value into the given equation
