Answer:
23/ 40 (0.57) yards of fabric
Step-by-step explanation:
Claire bought 9/10 of a yard of fabric to make her granddaughter a dress. She only used 3/4 of the fabric.
9/ 10 x 3 /4
9/10 x 3/4 = 27/ 40
1 - 27/40 = 40 -27
/40
Therefore, 23/ 40 (0.57) yards of fabric is used by Claire.

Answer: 5
Step-by-step explanation:
Using the options use the Pythagorean theorem
5^ 2 + 12^2 = 25 + 144 = 169
Sqrt(169) = 13
8 + 5 = 13
answer: t = 5
Answer:
343
Step-by-step explanation:
Big brain calculator work
28 + 35 + 42 + 49 + 56 + 63 + 70 = 343
The common difference is 19-7 = 31-19 = 12, so this is an arithmetic sequence. The initial term (when n=1) is 7.
The explicit formula for the terms of an arithmetic sequence is
an = a1 + d(n-1)
where "a1" is the first term and "d" is the common difference. The formula that matches a1=7 and d=12 is
B. a(n) = 7+(n-1)·12
