Put the measurements into the expression

(7)(5)

7•5 = 35

Triangle Area: 1/2bh

1/2(7)(2)

1/2(14)

Add them together: 35 + 7 = 42 cm²

Answer:

54 3/10 inches tall

Step-by-step explanation:

1 1/6 + 1 1/3 = 2 1/2

53 4/5 + 2 1/2 = 54 3/10

The height of Sheila is 62 ²³/₃₀ inches. Then the height of Jane will be 83 ³¹/₄₅ inches.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Cole is 53 ⁴/₅ inches tall. Sheila is 1 ¹/₆ inches taller than Cole. Then the height of Sheila is calculated as,

⇒ (53 ⁴/₅) × (1 ¹/₆)

⇒ 62 ²³/₃₀

Jane is 1 ¹/₃ inches taller than Sheila. Then the height of Jane is calculated as,

⇒ (62 ²³/₃₀) × (1 ¹/₃)

⇒ 83 ³¹/₄₅ inches

The height of Sheila is 62 ²³/₃₀ inches. Then the height of Jane will be 83 ³¹/₄₅ inches.

Answer:

70

Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.

Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.

40 + 2x = 180. Subtract 40 from both sides.

2x = 140. Divide both sides by 2.

X = 70

d = number of dimes

n = number of nickels

The jar contains a total of 107 coins, so

d + n = 107

Each dime is worth $0.10 and each nickel is worth $0.05, and the jar contains a total value of $6.70, so

0.10d + 0.05n = 6.70

Multiply both sides of the second equation by 100 to eliminate the decimal points:

10d + 5n = 670

Multiply both sides of the first equation by -5:

-5d - 5n = -535

Add the corresponding sides of these two equations to eliminate n and solve for d :

(10d + 5n) + (-5d - 5n) = 670 + (-535)

(10 - 5)d + (5 - 5)n = 670 - 535

5d = 135

d = 135/5 = 27

Then

n = 107 - d = 80

so the jar contains 27 dimes and 80 nickels.

Answer:

Step-by-step explanation:

This actually happened to me. I was walking out of a national forest and came up to a stream that I had not crossed. I got my bearings confused and realized I was lost.  I knew that if I went Northwest it would be about a 30 mile hike out in heavy woods, with obvious other streams to cross. In the Southeast direction, it would only be about 5 miles.

The sun was out but mostly overhead and no help with directions.

I couldn't wait until the sun went farther West to get my directions. It was a warm Winter day but I wasn't dressed to be there after dark when the temperature fell, even if I did go in the correct direction.

I stuck a stick in the ground and made a mark in the dirt at the end of it's shadow. I sat down for about 15 minutes, then made a new mark in the dirt at the end of the sticks shadow again. I drew a line in the dirt to connect the two marks. This line ran close to the East/West direction, the first mark being the West direction.

I made it out about 5 PM just as the sun was disappearing through the trees.

Answer:

y=-x/3+2

Step-by-step explanation:

If you graph out 3x-y-7=0, you will get a line that goes through the points (0, -7), and about (2.3, 0). If you graph out y=x/3+2, you have to make sure that this line forms a 90 degree angle on the previous line, thus making this line perpendicular to the previous line.

Answer:

Time taken by the ball to reach the maximum height = 5/32 seconds

Step-by-step explanation:

To find the time at which maximum height is reached , we will differentiate the given equation  with respect to t

[tex]\frac{db_{(t)}}{dt} = -32t + 5 = 0\\t = \frac{5}{32} \\[/tex]

Substituting this value of t in formula of b(t), we get

[tex]-16 * (\frac{5}{32})^2 + 5 * \frac{5}{32} + 15 \\= 15.390[/tex]

Answer:

Surface area is 96cm^2, volume is 64 cm^3.

Step-by-step explanation:

Surface area = area of top and bottom + area of left and right + area of front and back.

area of top or bottom = 4×4=16cm^2

area of left or right = 4×4= 16cm^2

area of front or back = 4×4=16cm^2

total surface area = 2(16) + 2(16) + 2(16) = 96cm^2

volume of a cube = length × width × height = 4×4×4 r 64 cm^3.
