The total surface area of the pyramid is:260 ft²
What is the total surface area of the Pyramid?The area of a triangle is expressed as:
A = ¹/₂bh
where:
b denotes the base of the triangle
h denotes the height of the triangle
Area of rectangle is:
A = l * w
where:
l denotes the length of the rectangle
w denotes the width of the rectangle
Thus, the total surface area of the given pyramid is:
Total Surface Area = 4(¹/₂(10 * 12)) + (10 * 10)
Total Surface Area = 240 + 20
Total Surface Area = 260 ft²
Therefore, we can conclude that is the calculation of the total surface area of the composite figure.

How many quarters do you need to add to 31/4 to get 41/2
Answer:
51/4 quarters
Step-by-step explanation:
To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator for 4 and 2 is 4x2=8.
So we need to convert both fractions to have a denominator of 8:
31/4 = (31/4) x (2/2) = 62/8
41/2 = (41/2) x (4/4) = 164/8
Now we can add the fractions:
62/8 + x/4 = 164/8
Subtracting 62/8 from both sides:
x/4 = 102/8
Simplifying:
x = 51/4
Therefore, we need to add 51/4 quarters to 31/4 to get 41/2
g(x)=2x
h(x)=x^(2)+4
evaluate for g(h(-8))
The value of the function is 136
How to determine the functionIt is important that we note that functions are described as expressions that are used to explain the relationship between two variables.
From the information given, we have that;
g(x)=2x
h(x)=x^(2)+4
To determine the composite function, we would need to substitute the value of h(-8) as x in the function g(x)
Then, we have that;
h(-8) = (-8)^2 + 4
Find the values
h(-8) = 68
Now, substitute the value as x , we have that;
g(h(-8)) = 2(68)
expand the bracket and multiply
g(h(-8)) = 136

The area of the composite figure is equal to 75.5 square meters
How to calculate for the area of the figureThe composite figure can be observed to be made up of a big rectangle, a smaller rectangle, a triangle and a smaller triangle. We calculate for the area of the four shapes and sum the results to get the total area of the composite figure as follows:
area of the big rectangle = 6 m × 4 m = 24 m²
area of the smaller rectangle = 7 m × 2 m = 14 m²
area of the big triangle = 1/2 × 10 m × 6 m = 30 m²
area of the smaller triangle = 1/2 × 5 m × 3 m = 7.5 m²
total area of the composite figure = 24 m² + 14 m² + 30 m² + 7.5 m²
total area of the composite figure = 75.5 m²
Therefore, the area of the composite figure is equal to 75.5 square meters

If GI and JL are parellel lines and m
The measure of angle IHE is 23°.
Since DF and GI are parallel, we know that angle HJF is congruent to angle GHJ. Therefore, we have:
mHJF = mGHJ = 134°
We can now use this information to find the measure of angle IHE. To do this, we need to use the fact that the sum of the angles in a straight line is 180°. Since H, J, F, and I lie on a straight line, we have:
mHJF + mFJI + mIHE = 180°
Substituting the values we know, we get:
134° + mFJI + mIHE = 180°
Simplifying the equation, we get:
mFJI + mIHE = 46°
We still need to find the measure of angle FJI. To do this, we can use the fact that the angles in a triangle add up to 180°. Triangle GHJ is a straight line, so its angles add up to 180°. Therefore, we have:
mGHJ + mHJF + mFJI = 180°
Substituting the values we know, we get:
134° + mFJI + mFJI = 180°
Simplifying the equation, we get:
2mFJI = 46°
Dividing both sides by 2, we get:
mFJI = 23°
Finally, we can substitute this value back into our earlier equation to find the measure of angle IHE:
mFJI + mIHE = 46°
23° + mIHE = 46°
Subtracting 23° from both sides, we get:
mIHE = 23°

A laptop computer is purchased for $4700. Each year, it’s value is 80% of its value the year before. After how many years will the laptop computer be worth $1000 or less?
Answer:
Step 1:
Let x = number of years
Let y = Value of the laptop after x years
Step 2:
Write an equation that expresses the value of the laptop after x years y = 0.8((4700)x)
Step 3:
Set the equation equal to 1000 and solve for x
1000 = 0.8((4700)x)
1 = 0.8(4700)x
1/0.8 = 4700x
1.25 = 4700x
x = (1.25/4700)

50 Points! Multiple choice algebra question. Find the domain and range of the function whose graph is shown. Photo attached. Thank you!
Answer:
"B". Domain is all real numbers, and the Range is all positive real numbers
Step-by-step explanation:
It is important to recognize that this function is an exponential function, either by the graph (observe a horizontal asymptote on the x-axis, and increasing exponentially), or more importantly by the equation which is in exponential form [tex]y=a*b^x[/tex] where "a" is a non-zero real number, and "b" is a positive real number not equal to 1.
Observe that for the given function, a=4 (a real number not equal to zero), and b=2 (a positive real number that is not 1).
The domain for all exponential functions is all real numbers, so this function's domain is all real numbers.
The Range for exponential functions depends on "a", where if "a" is a positive number the Range is positive numbers only, and if "a" is a negative number, the Range is negative numbers only.
Since "a" is positive, the Range is positive numbers only.
Writing the Domain in "set-builder notation" (since all of the choices are given using that notation), the Domain is "all real numbers" put into curly brackets, so {all real numbers}.
Writing the Range in "set-builder notation", recall that the Range is the outputs of the function, so the Range is "y values such that y is greater than zero". There is some shorthand used, where the phrase "such that" is symbolized using a short vertical line (common in set-builder notation), and the phrase "y is greater than zero" is shortened using inequality symbols "y>0". So, the Range is written as { y | y>0 }.
Further, the "Domain" and "Range" are abbreviated with "D" and "R" respectively.
Therefore, the final answer would be D = {all real numbers}; R = { y | y>0 }, which is answer "B"

In a shipment of 1,750 seeds of each type, how many more defective bean seeds would be expected than pumpkin seeds?
There would be 35 more defective bean seeds than pumpkin seeds in the shipment.
How to solveCalculate the number of defective bean seeds:
Defective bean seeds = Total bean seeds * Defect rate for bean seeds
Defective bean seeds = 1,750 * 0.05 = 87.5
Since we can't have half a seed, we'll round it up to the nearest whole number.
Defective bean seeds = 88
Calculate the number of defective pumpkin seeds:
Defective pumpkin seeds = Total pumpkin seeds * Defect rate for pumpkin seeds
Defective pumpkin seeds = 1,750 * 0.03 = 52.5
Similarly, we'll round it up to the nearest whole number.
Defective pumpkin seeds = 53
Calculate the difference in defective seeds:
Difference in defective seeds = Defective bean seeds - Defective pumpkin seeds
Difference in defective seeds = 88 - 53 = 35
So, there would be 35 more defective bean seeds than pumpkin seeds in the shipment.

A third-quadrant angle measured from the +x axis has a negative secant. The tangent is positive there.
Since this angle is measured from the -x axis, it isn't clear whether it is supposed to be considered a 3rd-quadrant angle or not. For the given acute angle θ shown, the trig functions are both positive. YMMV

Find the work done in pushing a car along a level road from point A to point B, 79 feet from A, while exerting a constant force of 103 pounds. Round to the nearest foot-pound.
The work done is
foot-pounds
The work done in pushing the car along the level road from point A is found to be 8147 foot-pounds.
The work done in pushing a car along a level road can be calculated using the formula,
work = force × distance × cos(angle) where the angle between the force and the direction of motion is 0 degrees (since the force is parallel to the level road). The force is given as 103 pounds, and the distance is 79 feet. Therefore,
work = 103 × 79 × cos(0) = 8147 foot-pounds
Rounding to the nearest foot-pound, the work done in pushing the car from point A to point B is 8147 foot-pounds.
