Answer:

A. 320 ft²

B. 2,304 ft²

Step-by-step explanation:

A. Area of one triangular face = area of triangle = ½*b*h

Where,

b = 32 ft

h = 20 ft

A = ½*32*20 = 16*20

A = 320 ft²

Area of 1 triangular face = 320 ft²

B. Total surface area = area of the 4 triangular face + area of the base of the square pyramid

T.S.A = 4(320) + (s²)

Where,

s = 32 ft

T.S.A = 4(320) + (32²)

T.S.A = 1,280 + 1,024

= 2,304 ft²

Step-by-step explanation:

The perimeter of the square is 16√5 mm, and the area of the square is 80 mm².

To calculate the perimeter and area of the square, we can use the formulas:

Perimeter = 4 * side length

Area = side length * side length

Substituting the given side length of 4√5mm into the formulas, we have:

Perimeter = 4 * 4√5mm = 16√5mm

Area = (4√5mm) * (4√5mm) = 16 * 5mm = 80mm²

Therefore, the perimeter of the square is 16√5mm, and the area of the square is 80mm².

Please note that the values are based on the provided side length of 4√5mm. If there are any changes to the side length, the perimeter and area will differ accordingly.

The required present value needed now to get $700 after 4 years at 11% compounded monthly is $451.73.

To find the present value of $600 after 4 years at 7% compounded monthly, we can use the formula for compound interest:

Compound Interest =P(1+r/n)^rt

Substituting the given values, we get:

Compound Interest =600 (1+7/n)^4

Simplifying this equation, we get

P = 600 / 1.487

P = 451.73

Here are the correct matches to the expressions to their solutions.

The GCF of 28 and 60 is 4.

(-3/8)+(-5/8) = -4/4 = -1.

-1/6 DIVIDED BY 1/2 = -1/6 X 2 = -1/3.

The solution of 0.5 x = -1 is x = -2.

The solution of 1/2 m = 0 is m = 0.

-4 + 5/3 = -11/3.

-2 1/3 - 4 2/3 = -10/3.

4 is not a solution of -4 < x.

1. The GCF of 28 and 60 is 4.

The greatest common factor (GCF) of two numbers is the largest number that is a factor of both numbers. To find the GCF of 28 and 60, we can factor each number completely:

28 = 2 x 2 x 7

60 = 2 x 2 x 3 x 5

The factors that are common to both numbers are 2 and 2. The GCF of 28 and 60 is 2 x 2 = 4.

2. (-3/8)+(-5/8) = -1.

To add two fractions, we need to have a common denominator. The common denominator of 8/8 and 5/8 is 8. So, (-3/8)+(-5/8) = (-3 + (-5))/8 = -8/8 = -1.

3. -1/6 DIVIDED BY 1/2 = -1/3.

To divide by a fraction, we can multiply by the reciprocal of the fraction. The reciprocal of 1/2 is 2/1. So, -1/6 DIVIDED BY 1/2 = -1/6 x 2/1 = -2/6 = -1/3.

4. The solution of 0.5 x = -1 is x = -2.

To solve an equation, we can isolate the variable on one side of the equation and then solve for the variable. In this case, we can isolate x by dividing both sides of the equation by 0.5. This gives us x = -1 / 0.5 = -2.

5. The solution of 1 m = 0 is m = 0.

To solve an equation, we can isolate the variable on one side of the equation and then solve for the variable. In this case, we can isolate m by dividing both sides of the equation by 1. This gives us m = 0 / 1 = 0.

6. -4 + 5/3 = -11/3.

To add a fraction and a whole number, we can convert the whole number to a fraction with the same denominator as the fraction. In this case, we can convert -4 to -4/3. So, -4 + 5/3 = -4/3 + 5/3 = -11/3.

7. -2 1/3 - 4 2/3 = -10/3.

To subtract two fractions, we need to have a common denominator. The common denominator of 1/3 and 2/3 is 3. So, -2 1/3 - 4 2/3 = (-2 + (-4))/3 = -6/3 = -10/3.

8. 4 is not a solution of -4 < x.

The inequality -4 < x means that x must be greater than -4. The number 4 is not greater than -4, so it is not a solution of the inequality.

For part (a), using the square root property, take the square root of both sides of the equation. Thus, will eliminate the radical symbol on the left side of the equation.

Note that the right side will either be positive or negative. This is because when we square both 8 and -8, we will obtain 64.

From the obtained equation, subtract 7 from both sides.

Thus, we will obtain two possible values of x.

Therefore, for part (a), the value of x is -15 or 1.

For part (b), isolate the variable term by subtracting 10 from both side of the equation.

Divide both sides of the equation by 5.

Similarly, take the square root of both sides of the equation by usng the square root property.

Therefore, for part (b), the value of x is either approximately -4.47 or 4.47.

Answer:

y = -x

Step-by-step explanation:

the formula for the equation of a straight line is:

y = mx + c

where m is the gradient (slope) of the line and c is the y-interxept

We are given the slope m = -1 and the point (5,-5)

y = -5, m = -1 and x = 5

Substitute these values into the equation to find c:

y = mx + c

-5 = -1(5) + c

-5 = -5 + c

-5 + 5 = c

c = 0

So the equation is:

y = -x

35 inches on the map will translate to an actual distance of 700 miles (fourth option).

The first step is to determine the scale of the map. In order to determine the scale, divide the actual distance between the two cities by the distance on the map.

Scale = distance between the two cities / distance on the map

Scale = 500 / 25  = 20

Now, multiply the distance on the map by the scale.

Distance in miles = 20 x 35 = 700 miles

Using balanced billing, the monthly payment is $278

Using balanced billing to determine their monthly payment, we simply need to divide their total annual payment by the total number of months in a year. This will result to dividing the entire annual bill by 12 to determine the monthly payment.

Given that the Ross family spent $3,336 for electricity last year, we can calculate their monthly payment as follows:

Monthly payment = Total cost / Number of months

Monthly payment = $3,336 / 12

Monthly payment  = $278

Step-by-step explanation:

Using the law of cosines, the measure of the angles are  

α ≈ 127°

β ≈ 28°

γ ≈ 25°

From the question, we are to solve the triangle.

To solve the triangle, we will determine the value of the unknown angles.

Using the law of cosines, we can write that

cosα  = (b² + c² - a²)/2bc

From the given information,

a = 34

b = 20

c = 18

Thus,

cosα  = (20² + 18² - 34²)/2(20)(18)

cosα = -432/720

cosα = -0.6

α = cos⁻¹(-0.6)

α = 126.8699°

α ≈ 127°

Calculating angle β

cosβ  = (a² + c² - b²)/2ac

cosβ = (34² + 18² - 20²)/2(34)(18)

cosβ = 1080/1224

β = cos⁻¹(1080/1224)

β = 28.0724°

β ≈ 28°

To determine angle γ

α + β + γ = 180° (Sum of angles in a triangle)

127° + 28° + γ = 180°

155 ° + γ = 180°

γ = 180° - 155°

γ ≈ 25°

Hence,

α ≈ 127°

β ≈ 28°

γ ≈ 25°
