Answer:
30 + 5<em>d</em> ≥ 120
Step-by-step explanation:
One ticket costs $120 and she already has $30 saved up so the money she makes by dogwalking added to the $30 has to be equal to or greater than 120
- 30 for the <u>amount she saved up</u>
- 5<em>d</em> where <u><em>d</em></u><u> stands for the number of days she walks dogs </u>
- Make this information into one part of the inequality: 30+5<em>d</em>
- Then this has to be greater than or equal to 120 so:
<u>30+5</u><em><u>d</u></em><u>≥120</u>
Hope this helps!
Since the two slant sides have equal length, the triangle is isosceles.
If a triangle is isosceles, the two angles at the base have equal measure.
So, the measures of the angles are 38, x and x. The sum of the angles is 180, so we have
3.73
If the number is 5 or higher you round up.
Hi,
The first thing you have to remember, that the sum of all probabilities are equal to 1.
As you have only 4 items : Pasta + Fish + Pizza +Salad
So pasta + fish + pizza +salad = 1
1 means every client who bought something had something to eat.
So now it simple :
We know the probability of every other items, so we will find the probabilty of salad by substracting off 1 every other probabilities.
<u>Remind yourself to always have data in same shape/ units etc.</u>
Here we have percentage, fraction, numbers.... can be confusing.
So convert all in same shape. I 'm going to convert all in numbers, as it seems to me the simpliest.
I will call probability of salad "X" as it usually like that we call something unknown in math.
So pasta = 15 % = 15/100 = 0.15
fish = 0.2
pizza = 3/10 = 0.3
salad = X
So now we have :
pasta + fish + pizza +salad = 1
replace by what I know :
0.15 +0.2+0.3 + X = 1
0.65 + X = 1
0.65 +X -0.65 = 1 - 0.65
X = 0.35
Salad probability is 0.35 , which means 35 % .
