Answer:
Step-by-step explanation:
Amount of calories per hour whkie riding = 236
Amount of calories she intends to burn = 590
The number of hours she must ride her bike :
Let number of hours = x
Hence,
(Calories burned per hour * number of hours) ≥ 590
(236 * x) ≥ 590
x ≥ 590 / 236
x ≥ 2.5
Hence she must rise her bike for 2.5 hours

solve each equation 7:x=2:3
7 : x = 2 : 3
- divide 7 by 2.
7/2 = 3.5
- this is the scale factor.
- now multiply this by 3.
3 X 3.5 = 10.5
so, x = 10.5

Step-by-step explanation:
If angle 1 is 121 degrees, then angle 7 is 59 degrees. (same side exterior angles)
If angle 8 is 103 degrees, then angle 4 equals 103 degrees (corresponding angles) and angle 3 is 77 degrees. (to angle 4 supplementary angles)
If angle 5 is 116 degrees, then angle 3 is 64 degrees. (same side interior angles)
  hurry please! 20 points. Find the measure of angle θ. Round your answer to the nearest tenth place.
Answer:
Angle θ would be about 17.1 degrees.
Step-by-step explanation:
To figure out what Angle θ is, first we have to find the hypotenuse. You can easily do that by find the square root of BC² + AC².
c = √4² + 13²
Square 4 and 13 to get 16 and 169 respectively.
c = √16 + 169
Add 16 and 169 to get 185.
c = √185
Find the square root of 185 (I'll round to the nearest tenth.)
c = 13.60147 ≈ 13.6 units
To find angle β, divide AC by AB and find the inverse sine of that.
β = arcsin(13/13.6)
Divide 13 by 13.6. Round to the nearest thousandth.
β = arcsin(0.955)
β ≈ 1.2723 rad
To convert radians to degrees, multiply the radians by 57.2957795 for an approximate amount.
β ≈ (1.2723 * 57.2957795)°
β ≈ 72.8974203 ≈ 72.9 degrees
Now subtract 72.9 from 90 to get angle θ's measure of 17.1 degrees.
Two times the difference of a number and four.

Is h = 8 a solution to the inequality below?
12h > 95
yes
no
Answer:
Yes
Step-by-step explanation:
12h>95
12*8>95
96>95
Answer: Yes
Step-by-step explanation:
Plug in 8 for h into the inequality 12h > 95.
[tex]12*8 > 95[/tex]
[tex]96>95[/tex]
Because 96 is greater than 95, the inequality is true.

There are 3 consecutive integers that sum to 51. What is the greatest integer of the three?
O 17
O
19
O 18
O 20
Answer:
C. 18
Step-by-step explanation:
Let's say the first number is x so the second will be x+1 and the third will be x+2
x+ x+1+x+2=51
3x+3=51
3x=51-3
3x=48
3x/3=48/3
X=16 this is the first number
The second number will be x+1=16+1=17
The third number will be x+2=16+2=18
So the greatest number will be 18

Write an equivalent expression with 3 terms for the expression below.
(-4y - 16) - 8y + 10 + 2y
Answer:
[tex]\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y=-10y-16+10[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y[/tex]
Remove the parentheses
[tex]=-4y-16-8y+10+2y[/tex]
Group like terms
[tex]=-4y-8y+2y-16+10[/tex]
simplifying
[tex]=-10y-16+10[/tex]
Therefore, the equivalent expression with 3 terms for the expression is:
[tex]\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y=-10y-16+10[/tex]

There are two bags containing only yellow and orange marbles. Bag A has 9 yellow marbles and 3 orange marbles. Bag B has 7 yellow marbles and 13 orange marbles. A marble is randomly chosen from each bag. List these events from least likely to most likely. Event 1 : choosing a yellow or orange marble from Bag B. Event 2 : choosing a red marble from Bag A. Event 3 : choosing an orange marble from Bag B. Event 4 : choosing a yellow marble from Bag A.
Answer:
Event 2, Event 3, Event 4, Event 1
Step-by-step explanation:
The probability of Event 2 occurring is 0/12(0%) as there are no red marbles in the bag.
The probability of Event 3 occurring is 13/20(65%) as you will get an orange marble from Bag B 13 out of 20 times.
The probability of Event 4 occurring is 9/12(75%) as you will get a yellow marble from Bag A 9 out of 12 times.
The probability of Event 1 occurring is 20/20(100%); therefore you will always get either a yellow or an orange marble from Bag B.
In ASTU, MZS = (2x + 10)°, mZT = (3x – 9)°, and mZU = (6x-19)
Find mZT.
9514 1404 393
Answer:
m∠T = 45°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so ...
(2x +10)° +(3x -9)° +(6x -19)° = 180°
11x -18 = 180 . . . . . collect terms, divide by °
11x = 198 . . . . . . . . add 18
x = 18 . . . . . . . . . . . divide by 11
Then the angle of interest is ...
m∠T = (3x -9)° = (3·18 -9)°
m∠T = 45°
_____
The other angles are ...
m∠S = 46°
m∠U = 89°
184500 $ are to be divided between 2 people. One person has 80% of what the other person has. How much does each one receive in $?
Given:
$184500 are to be divided between 2 people.
One person has 80% of what the other person has.
To find:
The amount each one receive in $.
Solution:
Let $x be the amount received by first person. Then,
Amount received by the second person = 80% of x
= 0.80x
Total amount = Amount received by first person + by second person
=[tex]x+0.80x[/tex]
=[tex]1.80x[/tex]
Total amount is 184500. So,
[tex]1.80x=184500[/tex]
[tex]x=\dfrac{184500}{1.80}[/tex]
[tex]x=102500[/tex]
So, the amount received by the first person is $102,500.
[tex]0.80x=0.80\times 102500[/tex]
[tex]0.80x=82000[/tex]
So, the amount received by the second person is $82,000.
