Answer:
Total surface area of the pyramid is 236.16cm² and the expression is
2bs + s²
Step-by-step explanation:
Total surface area of a square pyramid is expressed as;
TSA = 2bs + Base Area
b is the side length of the base = 8.2cm
s is the slant height of the triangular side = 10.3cm
Base area = s²
Base area = 8.2²
Base area = 67.24cm²
TSA = 2(8.2)(10.3)+67.24
TSA = 168.92+67.24
TSA = 236.16cm²
Hence the total surface area of the pyramid is 236.16cm² and the expression is 2bs + s²

The flight path of a plane is a straight line from city J J to city K K. The roads from city J J to city K K take the long way around, traveling 9.4 9.4 miles south and then 15.1 15.1 miles east. How many degrees east of south is the plane's flight path, to the nearest tenth? M ∠ J ≈ ? M∠J≈
Answer:
58.1 degrees
Step-by-step explanation:
Given the following
JK = 9.4miles (towards south) negative y axis
If the move 15.1 miles towards east (that will be towards the positive x axis)
Using the SOH CAH TOA identity
opposite= 15.1 miles(side facing m<J)
adjacent= JK = 9.4miles
tan theta = opposite/adjacent
tan m<J = 15.1/9.4
tan m<J = 1.6063
m<J = arctan (1.6063)
m<J = 58.09 degrees
Hence the measure of m<J to the nearest tenth is 58.1 degrees

Answer:
[tex]a_{15} = 2147483648[/tex]
Step-by-step explanation:
first, find the common ratio (r) by dividing the second term by the first term:
r = 32 / 8 = 4
next, write a formula for the geometric sequence:
[tex]a_{n} = a_{1} * (r)^{n-1} \\a_{15} = 8 * (4)^{14} \\a_{15} = 2147483648[/tex]

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?
Answer:
1.53 times
Step-by-step explanation:
Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?
We would have:
First strain : Second strain
0.000000143 mm : 0.0000000937 mm
How much larger is the first strain than the second?
We divide both by the length of the second strain
0.000000143/0.0000000937 : 0.0000000937 / 0.0000000937

, GIVING FIRST ANSWER BRAINLIEST! How many milliliters are in 1 liter?
Answer: 1000 mL
Step-by-step explanation:
Answer: 1000 Milliliters
Step-by-step explanation:
Convert 1 Liters to Milliliters
To calculate 1 Liter to the corresponding value in Milliliters, multiply the quantity in Liters by 1000 (conversion factor). In this case, we should multiply 1 Liters by 1000 to get the equivalent result in Milliliters:
1 Liters x 1000 = 1000 Milliliters
1 Liter is equivalent to 1000 Milliliters.
Quick conversion chart of milliliters to liters
1 milliliters to liters = 0.001 liters
10 milliliters to liters = 0.01 liters
50 milliliters to liters = 0.05 liters
100 milliliters to liters = 0.1 liters
200 milliliters to liters = 0.2 liters
500 milliliters to liters = 0.5 liters
1000 milliliters to liters = 1 liters
The equation of the line is of the form y = mx, What is the value of m?
Answer:
-4
Step-by-step explanation:
m is the slope
Answer:
m=-4
Step-by-step explanation:
in the formula y=mx, m is the slope. You can find it by looking at the graph, and finding two points that are defined on the grid. In this case, we can use (0,0) and (-1,4). Put it into the slope formula, (y2-y1)/(x2-x1). In this case, it would be (4-0)/(-1-0), which simplifies to 4/-1=-4. Therefore, m= -4
Janie has 2 3/4 yards or yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks
Answer:
1 3/8 yards
Step-by-step explanation:
Janie has 2 3/4 yards of yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks
The above question is calculated as:
2 3/4 yards × 1/2 of ribbon
= 2 3/4 × 1/2
= 11/4 × 1/2
= 11/8
= 1 3/8 yards
Therefore, Janie used 1 3/8 yards of ribbon for her bookmarks
