Answer:
600
Step-by-step explanation:
.7x = 420
x = 420/0.7
x = 600
300%= 9,000
20%= 60
5%= 15
9,000+60+15= 9,075
answer: £9,075
D. y = 10x, in 8 years she will have saved $8,000.
Since every year Cora saves $1,000. So $1,000 × 8 = $8,000.

<h3>7. Cos Z </h3>
=> Cos theta = Base /Hypotenuse
=> Cos Z = 30/50 => 3/5
★ So, Option <u>B) 3/5 </u> is a correct answer.
_______________________
<h3>8. Cos X </h3>
=> Cos theta = Base/Hypotenuse
=> Cos X = 12/37
★ So, option <u>D)</u><u> </u><u>1</u><u>2</u><u>/</u><u>3</u><u>7</u> is a correct answer.

<h3>9. Sin Z</h3>
=> Sin theta = Perpendicular/Hypotenuse.
Sin Z = 16/20 => 4/5
★ So, option <u>C)</u><u> </u><u>4</u><u>/</u><u>5</u> is a correct answer
<h3>_____________________</h3>
<h3>10. Sin Z </h3>
=> Sin theta = Perpendicular/Hypotenuse
Sin Z = 48/50 => 24/25
★ So, option <u>A)</u><u>2</u><u>4</u><u>/</u><u>2</u><u>5</u> is correct answer
