Answer:

[tex]=31.64ft^2[/tex]

Step-by-step explanation:

Triangle

[tex]A=\frac{h_{b}b }{2} \\=\frac{4*6}{2}\\=12ft^2[/tex]

Semicircle

[tex]A=\frac{\pi r^2}{2}\\=\frac{\pi 2.5^2}{2} \\=9.82ft^2\\[/tex]

because both semicircle are the same just multiply by 2

[tex]9.82*2\\=19.64ft^2[/tex]

Now add all together

[tex]12+19.64\\=31.64ft^2[/tex]

Answer:

31.64 ft*2

Step-by-step explanation:

Break down the problems by shapes-

1. Triangle= 4 x 6/2

=12 ft*2

2. Semi-Circle= 2.5/2 (sense their are two, we only need to solve one)

=9.82 ft*2

Multiply 9.82 by 2  

=19.64 ft*2

Adding all together

12+ 19.64

=31.64 ft*2

Answer:

y=6

Step-by-step explanation:

step 1:

26 • (7y + 8) - 1300 = 0

Step 3:

Pulling out like terms :

3.1     Pull out like factors :

182y - 1092  =   182 • (y - 6) 

Equation at the end of step 3:

182 • (y - 6) = 0

Step  4  :

Equations which are never true :

4.1      Solve :    182   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2      Solve  :    y-6 = 0 

Add  6  to both sides of the equation: 

                      y = 6

Answer:

The tangent of ∠L represents the ratio between side NM and side LN.

The value of this tangent is 0.9028

Step-by-step explanation:

The angle ∠N is 90°, so we have a right triangle. In a right triangle, the tangent of an angle represents the ratio between the opposite side of that angle and the adjacent side (the cathetus, not the hypotenusa) of that angle.

So, in the triangle LMN, the opposite side to the angle ∠L is NM, and the adjacent side is LN (ML is the hypotenusa, because it is the bigger side). The value of this tangent is:

tan(L) = NM / LN = 65 / 72 = 0.9028

Answer:

1,400 minutes

Step-by-step explanation:

First, let’s find how much time she spends per week.

She attends a class that is 40 minutes long and she does this 5 times a week.

Therefore, we can multiply 5 and 40 to find the total time per week.

5*40

200

She spends 200 minutes per week and she does this over a 7 week period.

We can multiply 200 and 7

200*7

1,400

She spends 1,400 minutes in yoga class over a 7 week period.

Answer:

1,400 minutes.

Step-by-step explanation:

Kerri attends a 40-minute yoga class 5 times per week.

Multiply 40 by 5 to get the total minutes for one week:

[tex]40*5=200[/tex]

So, Kerri attends yoga classes for 200 minutes total for one week.

With that in mind:

[tex]\text {Total Minutes for a Week} * \text {Weeks} =\\\rightarrow 200 * 7=\\\boxed {1400}[/tex]

Kerri should attend yoga classes for a 1,400 minute total in a seven week span.

Answer:

Total amount of $ at beginning of day ⇒ ( About ) $ 26.1

Step-by-step explanation:

Let us say x represents ⇒ amount of $ at the beginning of the day;

If she spent 1 / 6 of this total money on books, we can say that the amount spent on books is 1/6x. Consecutively if 1/8 of this money was spent on shoes, the amount spent on shoes is 1/8x;

Knowing that $13.50 was remaining, let us set up the following equation;

x - ( 1/6x + 1/8x + 5 ) = 13.50 ⇒ now let us solve for x,

x - ( 1/6x + 1/8x + 5 ) = 13.50 ⇒ add similar elements, expanding,

x - ( 7/24x + 5 ) = 13.50 ⇒ distribute the minus sign

x - 7/24x - 5 = 13.50 ⇒ multiply either side by 24,

17x - 120 = 324 ⇒ add 120 to either side,

17x = 444,

Solution; Total amount of $ at the beginning of day ⇒ ( About ) $ 26.1

Answer:

a) 72 cm^2

b) 9 cm^2

c) 9 cm^2

d) 60.39 cm^2

Step-by-step explanation:

a) the the length is 12 cm and the width is 6 cm. Area = lw

A=(12)(6)

A=72 cm^2

b) base equals 3 cm

Height equals 6 cm

A=1/2(3)(6)

A= 9 cm^2

c) base = 3 cm

height=6 cm

Area=1/2(3)(6)

A=9 cm^2

d) to to find the area of the parallelogram, You need to use Pythagorean theorem for one of the triangles.

3^2 + 6^2 = x^2

9 + 36 = x^2

45=x^2

✓45 = ✓x^2

x = 6.71 cm

12-3 = 9

now that you have all the sides for the parallelogram, multiply 6.71 times 9 to get the area.

A= 60.39 cm^2

The airplane is 48 feet long in real dimensions.

To find out how long the airplane actually is, we can use the scale and input our amount of inches that it is measured by.

So, 1 inch equals to 6 feet.

Our model plane is 8 inches.

Now, we plug it in.

8 inches = 6(8)

8 inches = 48 feet

Therefore, the length of the real airplane is 48 feet.

48 feet

Answer:

48 feet

Step-by-step explanation:

Let's create a proportion using the following setup.

inches/feet=inches/feet

We know the scale is 1 inch to 6 feet. We also know that the plane is 8 inches long, but we don't know how many feet long it is, so we can say x feet.

1 inch/6 feet= 8 inches/ x feet

1/6=8/x

Cross multiply. Multiply the numerator of the first fraction by the denominator of the second. Multiply the denominator of the first by the numerator of the second.

1*x=6*8

x=6*8

x=48

Add appropriate units, in this case: feet.

x= 48 feet

The actual airplane is 48 feet long.

So the right answer is 24.

Answer:

24

Step-by-step explanation:

Solve according to PEMDAS. Perform the operation inside the parentheses first, then evaluate exponents, multiply, divide, add and subtract.

(3-5)^4(2)-16/2

First, perform the operation inside the parentheses. Subtract 5 from 3.

(-2)^4 (2) -16/2

Next, evaluate the exponent. -2^4 is the same as multiplying -2, 4 times.

-2*-2*-2*-2=16

So, -2^4 is equal to 16

16(2)-16/2

Multiply 16 and 2.

32-16/2

Divide 16 by 2

32-8

Subtract 8 from 32

24

The correct answer is 24

Answer:

that would be 108

Step-by-step explanation: it's 108 b/c supplementary angle/ either of two angles whose sum is 180°.

Answer:

Let the angle be x .

Its supplementary = 180 - x

Given:

x = 180 - x - 72

2x = 108

x = 54

Other angle = 180 - 54 = 126

So the right answer is 15.57.

The relationship between [tex]\angle 1[/tex] and [tex]\angle 8[/tex] are Alternate Exterior Angles.

Step-by-step explanation:

Alternate Exterior Angles, are pair of angles that lie on the outside of the traversal and lie on the opposite sides.

The required name of the relationship between 1 and 8 is alternate exterior angles

The correct option is (c)

When a transversal cut the pair of parallel lines then the alternate exterior angles are congruent.

Consider the given pair of parallel lines and transversal

we have

angel 1 and 5 are corresponding angles

angle 2 ad 6 are corresponding angles

angle 1 and 8 are alternate exterior angle

angle 2 and 7 are also alternate exterior angle

Therefore the correct option is (c)

This is the conclusion to the answer.

Answer:

Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Step-by-step explanation:

4c + 6a ≤ 120:

You can set up the inequality 4c + 6a ≤ 120, because it takes 4 hours to build per child bike (c) and 6 hours to build an adult bike (a), all together this time cannot surpass 120 hours. That is why you use the 'less than or equal to' sign.

4c + 4a ≤ 100:

You can then set up the inequality 4c + 4a ≤ 100, because it takes 4 hours to test a child bike (c) and 4 hours to test an adult bike (a). Since 100 hours is the max amount of time they can use to test out bikes, you will use the 'less than or equal to' sign.

4(5) + 6(15) = 20 + 90 = 110. 110 is less than 120

4(5) + 4(15) = 20 + 60 = 80. 80 is less than 100

Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

A rational number is a number that can be written as a fraction.

The square root of 34 is equal to ~5.83. This number cannot be written as a fraction.

Pi is not a rational number. Its digits stretch into infinity and it does not have any factors.

The square root of 64 is a rational number. The square root of 64 is 8, which can be written as a fraction, as well as being an integer.

The square root of 102 is equal to ~10.1. This is not a rational number and cannot be written as a fraction.

Therefore, the square root of 64 (Or 8) is a rational number.
