Find the total surface area of the
following square pyramid:
4 cm
6 cm
SA = [?] cm^2
Answer:
Lateral surface area= 48cm^2
Step-by-step explanation:
for anyone who needs the lateral surface area.
The total surface area of the square pyramid with a base side length of 6 cm and a slant height of 4 cm is 84 square centimeters.
We have,
Base side length (s) = 6 cm
Slant height (l) = 4 cm
Area of square = s²
Area of base = 6² = 36 cm²
A square pyramid has four triangular lateral faces with equal area.
The formula for the area of a triangle.
Area of triangle = 1/2 * base * height
Area of lateral surface of the triangle = 1/2 * 6 cm * 4 cm = 12 cm²
Total lateral area = 4 * 12 cm² = 48 cm²
Total surface area = Area of base + Total lateral area
Total surface area = 36 cm² + 48 cm²
Total surface area = 84 cm²
Therefore,
The total surface area of the square pyramid with a base side length of 6 cm and a slant height of 4 cm is 84 square centimeters.

What is an equation of the line that passes through the points (0, -2) and (0,-5)?
Answer:
x = 0
Step-by-step explanation:
We can find slope using this formula:
[tex]\frac{y2 - y1}{x2 - x1} = slope[/tex]
So we plug it in like this:
[tex]\frac{-5 - -2}{0-0} = \frac{-3}{0} \\[/tex]
We see that the slope is undefined so it will be a straight vertical line
So in order to pass through y = -5 and y = -2, x would have to equal 0.
Therefore, the equation is x = 0

you have $155 in a savings account. you decide tobl add $20 to the account every week. write an expression that shows your savings after n weeks
Answer:155+20n
Step-by-step explanation:
Answer:
155+20n
Step-by-step explanation:
You start off with the base amount of money, or the constant. That's 155. Then you add 20 dollars per week, depending on how many weeks you are thinking of. That means you need to multiply 20 by the amount of weeks you have been adding money. So 20n. Then you add that to the base amount of money, 155, so the answer is 155+20n

the perimeter of a rectangle pool is 74 feet. if the length is one more than twice the width, find the dimensions of the pool
Step-by-step explanation:
let length of the pool be l feet and width be w feet.
l = 2w + 1 --(1)
2(l + w) = 74 --(2)
sub (1) into (2):
2(2w + 1 + w) = 74
6w = 72
w = 12
therefore, length is 25feet and width is 12feet

You must use 2 eggs to make 6 dozen cookies. How many eggs are needed to make 42 dozen
cookies? Use a proportion to solve.
Answer:
14 eggs
Step-by-step explanation:
Answer: It takes 14 eggs to make 42 dozen cookies
Step-by-step explanation: To solve using a proportion first start out with 2eggs/6cookies (They are in a dozen but 42 is also in a dozen so it cancels out). Now that you have 2/6 you now have to find the x in x/42. 42 divided by 6 is 7 so multiply 2 by 7 and you get: It takes 14 eggs to make 42 dozen cookies or 14/42. Hope this helps

Answer:

Step-by-step explanation:
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

Answer:
Step-by-step explanation:
16). m∠1 = m∠2 = m∠3 = m∠4 = 74°
m∠5 = m∠6 = m∠7 = m∠8 = 180° - 74° = 106°
17). m∠2 = m∠5 = m∠15 = 125°
m∠1 = m∠6 = m∠10 = m∠16 = 180° - 125° = 55°
m∠11 = 125° - m∠12 = 125° - 37° = 88°
m∠3 = m∠9 = m∠13 = m∠18 = 102°
m∠4 = m∠14 = m∠17 = 180° - 102° = 78°
m∠8 = 180° - (m∠12 + m∠13) = 180° - (102° + 37°) = 41°
m∠7 = m∠14 - m∠8 = 78° - 41° = 37°

Line a passes through the points (-2, 1) and (3, 6). What is the slope of a line parallel to line A?
Answer:
Slope = 1
Step-by-step explanation:
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Given points: (-2, 1), (3, 6)
(-2, 1) = (x1, y1)
(3, 6) = (x2, y2)
When two lines are parallel, their slopes are equal. So to find the slope of a line parallel to line A, all we need to do is find the slope of line A. To do this, input the given points into the formula used to find slope:
[tex]\frac{6-1}{3-(-2)}[/tex]
Simplify:
6 - 1 = 5
3 - (-2) = 3 + 2 = 5
[tex]\frac{5}{5}=1[/tex]
The slope of line A and the line parallel to it is 1.
Hope this helps :)
