<h3>Trina uses 3.44 or
pints of white paint</h3>
<em><u>Solution:</u></em>
Given that,
Trina uses 8.6 pints of blue paint and white paint to paint her bedroom walls
3/5 of the amount is blue paint, and the rest is white paint
From given,
3/5 of 8.6 pints is blue paint
Thus, 2/5 of 8.6 pints is white paint
<em><u>How many pints of white paint did she use to paint her bedroom walls?
</u></em>
Thus she uses 3.44 or 17.2/5 pints of white paint
Answer
a. The backpack is $4.50
b. The sweatshirt is $2.70
Step-by-step explanation:
a. 30 x 0.15 = 4.50 (The 0.15 is from the price you are actually paying for the item. Because the item is 85% off, you are paying for 15% of the usual price. 15% as a decimal is 0.15 so you multiply that to the original price to find the amount u will pay.)
b. 18 x 0.15 = 2.70
V=(1/3)hπr^2 where h=height and r=radius
given
radius=3
height=2a
r=3
h=2a
v=(1/3)hπr^2
v=(1/3)(2a)π(3)^2
v=(1/3)2aπ9
v=6aπ
so the expression would be some variaant of v=6aπ
sin 45 = opp/hyp
sin 45 = 4 / y
y = 4/sin 45
y = 4 /((sqrt2)/2)=4* sqrt(2)
tan 45 =opp/adj
tan 45 = 4/(x-3)
1 = 4/(x-3)
x-3 = 4
x=7
B
He makes 1,172.50. you find this by dividing 2345 by 2 (since that’s his BI weekly salary which means every 2 weeks he gets paid) when you divide by 2 you get 1,172.50
