Answer:
∠7=22°
Step-by-step explanation:
∠2 and ∠7 are supplementary angles, meaning they add to 90°.
∠2+∠7=90°
substitute ∠2
68°+∠7=90°
∠7=22°
So 10 questions is 100% you missed 30% of the questions so you would do 100%-30% which is 70%
Answer:
The store will sell the guitar for $58.50
Step-by-step explanation:
$45 * 1.3 = $58.50
Since the price they bought it for is $45 and the markup percent is 30%, we multiply $45 by 1.3, which will give us $58.50.
Answer: a multiple is a number that can be divided by another number without a remainder.
Step-by-step explanation: so what is not a multiple of four would be 2, 7, 15 19, 34.
keeping in mind that perpendicular lines have <u>negative reciprocal</u> slopes, hmmm what's the slope of y=2/3x-1 anyway?
so, notice, "one of his mistakes" is that he used 3/2 as the slope, not -3/2.
so, we're really looking for a line whose slope is -3/2 and runs through (-7, 1/2).
