The <em><u>correct answer</u></em> is:

a) 25q + 10d + 5n + 60 = 187

Explanation:

One dollar and 87 cents can be written as 1.87.  However, since one dollar is equal to 100 cents, we can also write this as 187 cents.

Each quarter, represented by q, is equal to 25 cents; this gives us the expression 25q.

Each dime, represented by d, is equal to 10 cents; this gives us the expression 10d.

Each nickel, represented by n, is equal to 5 cents; this gives us the expression 5n.

We have 60 pennies.

This gives us the equation 25q+10d+5n+60=187.

I think the answer to this is: 25q + 10d + 5n + 60 = 87

The story says that you have 1 dollar and 87 cents; 60 cents of which is pennies. So, if you’re using an equation involving quarters, dimes and nickels, the total equation should equal to 87 cents (since that dollar bill could not be broken down to cents).

Diameter of a cone base is 5 cm and a slant height is 4M find surface area
Nutka1998 [239]

Hi there!

The total surface area (tsa) of a cone can be calculated with this formula :

TSA = (\pi × r × slant height) + \pi × r²


The "r" stands for "radius". The radius is equal to half the diameter, so in order to be able to use the formula, you'll need to divide the diameter by 2 to find the radius :

5 ÷ 2 = 2.5 = radius


Since the slang height is in meters, you'll need to transform it into centimeters in order to have both values in centimeters. To do so you'll need to use the cross product method :

1 m = 100 cm

4 m = x cm

(100 × 4) ÷ 1 = x cm

400 ÷ 1 = x cm

400 = x cm → The slant height is 400cm.


Now replace all the information in the formula and calculate everything :

TSA = (\pi × 2.5 × 400) + (\pi × 2.5²)

TSA = (\pi × 1,000) + (\pi × 6.25)

TSA ≅ 3,141.59 + 19.63

TSA ≅ 3,161.22 cm²


There you go! I really hope this helped, if there's anything just let me know! :)

Please help. Find the value of x
Oliga [24]

Answer:

x  =24

Step-by-step explanation:

Call the angle in the lower right corner y

The outside angles add to 180 degrees for the large triangle

41+ 94+ y = 180

135 + y = 180

y = 180-136

y =45

The small triangle in the lower right also has angles that add to 180

y+ 111+x = 180

45+111+x = 180

156 + x = 180

x = 180-156

x =24
