Answer:
37 yd²
Step-by-step explanation:
The computation of the surface area of this triangular pyramid is shown below:
The surface area of this triangular pyramid is
But before that
Lateral area = 3(1 ÷ 2) × base × height
= (3 ÷ 2)(4 yd)(5 yd)
= 30 yd²
Now
base area = 1 ÷ 2 × base × height
= 1 ÷ 2(4 yd)(3.5 yd)
= 7 yd²
Now the total surface area is
surface area = lateral area + base area
= 30 yd² + 7 yd²
= 37 yd²

I am a 2-digit number. If sum of my two digits is added to the product of my digits, it is me again. Can you find me?
Answer:
Step-by-step explanation:
Let “ab” represent the digits of the number.
a ≠ 0
Value of the number = 10a+b
a+b + ab = 10a + b
a + ab = 10a
ab = 9a
b = 9
“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99
Answer: 49
Step-by-step explanation:
4x9=36
4+9=13
36+13=49

All edge are 8 cm in length. What’s the surface area?
Answer:
192
Step-by-step explanation:
This is because its a square and all the sides on a square are equal so it would be:
top/bottom= 8*8
left/ right= 8*8
front/ back= 8*8
all equal 64 then you do 64*64*64 to get 192!

Real life applications of chain rule
Answer:
The Chain Rule can also help us deduce rates of change in the real world. From the Chain Rule, we can see how variables like time, speed, distance, volume, and weight are interrelated. A horse is carrying a carriage on a dirt path.
One real-life application of the chain rule is the study of motion in a car that is traveling along a curved path.
What is the chain rule?The chain rule is a fundamental concept in calculus that enables us to calculate the derivative of composite functions.
Composite functions are functions that are constructed by combining two or more functions. The chain rule tells us how to calculate the derivative of a composite function by breaking it down into simpler parts.
One real-life application of the chain rule is in physics, specifically in the study of motion.
For example, suppose we have a car that is traveling along a curved path. We want to know the rate at which the car is changing its speed at a particular point on the path. To do this, we need to find the derivative of the car's speed with respect to time.

A factory worker loaded some boxes onto a cart . Each box has the same weight . This expression represents the total weight in pounds , of the cart and n boxes 10n + 25 Based on the expression , what is the weight , in pounds , of the cart ?
Answer:
25 pounds
Step-by-step explanation:
Sum of the weight of the boxes of the cart = 10n + 25
where n = number of boxes
10 would be the weight of each box.
total weight of the boxes = weight of each box x number of boxes
10 x n = 10n
The other variable is 25. this is the weight of the cart

Sam asked some other children which sport they like. They all choose swimming. Now the most children choose swimming. How many children did Sam ask?
Answer:
five or more than five
Step-by-step explanation:
From the chart, we know that,
Number of children who chose soccer = 7 (this was the highest)
Number of children who chose swimming = 3
So for swimming to be chosen the most, it should gave been chosen by more than 7 children, i.e. 8 children or more than 8.
So the difference between 8 children and 3 children is = 8 - 3
= 5
Thus, 5 is the least number of other children to chose swimming.
Therefore, Sam asked at least 5 number of children or more than 5.

Solutions 5x + 10 = 5x
Answer:
I think there is no solution to the equation. (I'm not sure what your asking)
Step-by-step explanation
The equation should equal 0, so you subtract 5x from both sides. Once you do that, it cancels out the 5x and leaves 10=0 which is a false statement.
