Answer:
Circumference, C = 81.68 units
Step-by-step explanation:
Given that,
The radius of the circle, r = 13 units
We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :
C = 81.68 units
So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
- 133 > -7(2x+3)
-133 > -14x - 21
-133 + 21 > -14x
-112 > -14x │ × (-1)
112 < 14x
14x > 112
x > 112/14
x > 8
Answer
8kg
Explanation
3/4--------15
2/5-------x
cross multiplying
3/4×X = 2/5×15
3X/4 = 30/5
3X/4 = 6
cross multiplying
3X = 4×6
3X = 24
dividing bothsides by 3
3X /3 = 24/3
X = 8
therefore, the answer is 8 kg
The true statement about the inequality is that Total sales per day is greater than $250
<h3>How to write and solve inequality equation?</h3>
- Amount earned per day = 25 + 5% of x
= 25 + 0.05x
- Thursday = 4th day of the week
The inequality:
4(25 + 0.05x) > 50
100 + 0.2x > 50
100 - 50 > 0.2x
50 > 0.2x
x > 50/0.2
x > $250

Step-by-step explanation:
The ratio is 4:3
First you would do 4 + 3 which is 7
Then you would do 35 ÷ 7 which is 5
Finally we would multiply 5 to the ratio 4:3
So 7 × 4 is 28
And 7 × 3 is 21
So the new ratio is 28:21
So there are 21 girls in the class
Hope this makes sense
