Answer:

E - 40°

Step-by-step explanation:

Angle O = 2 × y

{Angle at center is equal to twice the angle at circumference formed by the same arc}

O = 2 × 70°

O = 140°

x + 90° + 90° + O = 360°

{Sum of angles in a quadrilateral is equal to 360°}

x + 90° + 90° + 140° = 360°

x + 320° = 360°

x = 40°

A school is arranging a field trip to the zoo. The school spends 635.66 dollars on passes for 34 students and 3 teachers. The sc
Nataly [62]

Answer:

Step-by-step explanation:

Let the students price = x

Let the teacher's price = y

34x + 3y = 635

34y = 299.54

y = 299.54 / 34

y = 8.81

The only way to do this is to assume that students and teachers are charged the same amount for admission. But the question should say so.

So x = y

37x = 635.66

x = 635.66 / 37

x = 17.18

So the total spent per student was

8.81 + 17.18 = 25.99

GuDViN [60]

Answer:

$0.13 to produce each box.

Step-by-step explanation:

S= ph+2b

p= 12.5+2.5+12.5+2.5=30

h=25

b= 12.5x2.5=31.25

S= (30)(25) +2 (31.25)

S= 812.5cm^{2}

812.5 x 0.00016= 0.13

Math Help. Greatly Appreciated
Triss [41]
So we know that the perimeter is 1260 feet and that the length is 100 more than the width, but we don't know that the width is.
So we're going to start with finding the width.
w = (x + x + 100) = 1260
from there we need to combine like terms
x + x = 2x
now we have
2x + 100  = 1260
From there, we will need to remove 100 from both sides, leaving us with
2x = 1160
now we'll need to divide both sides by 2
2x \div 2x = x
1160 \div 2 = 580
We now know that the width is 580, or more simply put, x=580.

Finding the length will be the easy part, as we know that it is just 100 more than the width
580 + 100 = 680
If you want an easier way of finding the length, just subtract the width from the perimeter.
1260 - 580 = 680
Leaving the final answer to be
Width = 580
Length = 680

How much would $400 be worth after 6 years if it was invested at 2% interest compounded annually
Alexxx [7]
P=400 (your amount invested)
r=.02 (rate as a decimal)
n=1 (number of times compounded per year, annually meaning 1)
t=6 (number of years invested)

you must follow orders of operations when you plug these things in your calculator.
1st step) do .02/1 to get 0.2 then add 1 to get 1.02. raise this to (1*6)and you get roughly 1.126, now multiply this by 400 to get answer D 450.46.
