Answer:
Step-by-step explanation:
Hello, we can write this number ab where a and b are integer betwen 0 and 9.
For instance, 54, a = 5, b = 4
And then, we can say ab = 10 * a + b.
For instance, 54 = 50 + 4 = 5*10 + 4.
The sum of the digits of a two digit number is 10.
a + b = 10
When the dishes are reversed the number increases by 18.
10b + a = 18 + 10a + b
9b = 18 + 9a
b = 2 + a
We replace in the first equation to get.
a + 2 + a = 10
2a = 10 -2 = 8
a = 4
and then, b = 6
So, the number is 46.
Thank you
Answer:
A) (2x+15)=65=180°
Step-by-step explanation:
Hey there!
It's a straight line, which means that the sum will be 180°.
So, (2x+15)=65=180°

Hope this helps!
The length of side b is also probably 3cm, because thinking of a diamond shape, all of the sides are equal and It give you no other measurments
The answer is Quantitative methods.
Quantitative methods that aim to modify the social environment in a very particular way for a specified sample of people and then follow the outcomes of that change; they frequently entail comparisons to a control group that did not receive such an intervention.
What is Quantitative methods ?
- Quantitative methods stress objective measurements and statistical, mathematical, or numerical analysis of data gathered through polls, questionnaires, and surveys, as well as through modifying pre-existing statistical data using computing tools.
- Online surveys, paper surveys, mobile surveys and kiosk surveys, face-to-face interviews, telephone interviews, longitudinal studies, website interceptors, online polls, and systematic observations are all examples of quantitative data gathering approaches.
- For quantitative methods, there are two basic sampling methods: probability sampling and non-probability sampling.
