Answer:
20 gallon
Step-by-step explanation:
If you want to go 560 miles and you get 28 mpg you divide 560÷28 which is 20
She only asked the students in her ballet class, which is probably biased toward ballet. She should survey everyone in The Dance Academy. That way, the answers won't be biased.
Answer:
Step-by-step explanation:
- <em>During a mathematics activity, teacher Julieta distributed to each of her students 4 straws measuring 2 cm, 3 cm, 7 cm and 8 cm. In this activity, Julieta's students had to build triangles with these straws, without cutting them.
</em>
- <em>How many different triangles could each of Julieta's students form with these straws?</em>
==========================================================
- <em>Triangle inequality theorem says that no any side of a triangle can be longer or equal to the sum the other two sides</em>
<u>Given measures:</u>
<u>We see that:</u>
Therefore we can't make triangles with the sides of 2 cm, 3 cm and 7 cm or 8 cm
<u>Possible solutions are:</u>
- 2 cm, 7 cm, 8 cm
- 3 cm, 7 cm, 8 cm
So we can make two different triangles
I cant really see the numbers (3-4) which do u need
Answer:
<em>b = 50√c</em>
Step-by-step explanation:
If b varies directly as the square root of c, this is expressed as;
b∝√c
b = k√c
k is the constant of proportionality
Given b = 100 and c = 4
100 = k√4
100 = 2k
k = 100/2
k = 50
Substitute k = 50 into the original expression:
Recall that: b = k√c
b = 50√c
<em>hence equation that can be used to find other combinations of b and c is b = 50√c</em>
