Answer:
$490
Step-by-step explanation:
Shauna spent $175 on a pair of shoes.
She spent 1/9 of the remaining money on a shirt.
If he still had 4/7 of his money left,how much did he have at first ?
Solution:
Let at first, Shauna have =
Money spent on a pair of shoes = $175
Remaining money =
<u>As she spent 1/9 of the remaining money on a shirt.</u>
Money spent on shirt =
As he still had of his money left:-
Money left =
Money left with Shauna = Total money, she had at first -(Money spent on a pair of shoes + Money spent on shirt )
Subtracting both sides by and adding both sides by
Taking LCM of 7 and 9, we get 63
Adding both side by -
By cross multiplication:
Dividing both sides by 180
Therefore, total $490, she had at first.
Given:
Triangles FRI and DAY are similar.
To find:
Similarity ratio
Solution:
<em>If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.</em>
Here, FR and DA are corresponding sides.
Cancel the common factors of 4 and 6, we get
⇒ FR : DA = 2 : 3
⇒ ΔFRI : ΔDAY = 2 : 3
Similarity ratio of the first triangle to the second triangle is 2 : 3.
