Is the 161 rounded to the nearest 10 or to the nearest 100
Answer:
161 to the nearest 10 = 160
161 to the nearest 100 = 200
Step-by-step explanation:
161 to the nearest 10:
Since you know that 60 is the tenth unit in this number, and 1 is the one unit, the one unit will indicate if it should be rounded up or down. If the one unit it 4 and below, the number will be rounded down. If the one unit is 5 and above, the number will be rounded up.
With this information, we know that he one unit in this number is "1", which will make the 61, be rounded down to 60, resulting in 160.
Using the same information with rounding to the nearest 100, since the tenth unit is above 5, the number will be rounded to the nearest 100, which is 200.
You use the number before the number you are trying to round, to find the nearest "_th".
Answer:
if its rounded to the nearest 10 it would be = 160
if its rounded to the nearest 100 it would be = 200

A straight slide in a playground design makes an isosceles triangle with the
ground and its platform, with area 32 square feet. What is the length of the slide?
A 412 feet 32 © 8/2 feet 126
B 8 feet 6
0 16 feet 256
Answer:
Option D.
Step-by-step explanation:
First, the you need ti understand that the triangle is an isosceles right angled triangle. In other words, the base and height are equal in length. The third side is the slide. This is the longest side. Next, we know that the formula for calculating the area of a right angled triangle is given by:A = 1/2 (base × perpendicular height)
The perpendicular height is equal to the base. Let's say the base is x. It means that the height is also x, since height = base. Therefore, the formula will be:A = 1/2 (x.x)
=1/2 (x²)
32 = 1/2 (x²)
Multiplying both sides by 2 gives:
32×2 = x²
64 = x²
8 = x
To find the third side, we use the Pythagoras theorem:
C² = A² + B²
= 8² + 8²
= 128
C = √128
= 8√2
However, the answer will not be exact, so we multiply the length of the base and height by 2. This gives x = 16 (Length of base = length of height)
Repeating the steps above gives C = √ (16)² + (16)²
= √256
This corresponds to option D.

answer.
Answer:
Boden's conjecture is correct
Step-by-step explanation:
we know that
If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa.
A right triangle, has two acute angles.
The two acute angles are complementary
so
In any right triangle, the sine of one acute angle is equal to the cosine of the other acute angle
therefore
Boden's conjecture is correct
Answer:
Yes, because the leg opposite one of the acute angles is adjacent to the other acute angle

Write two equations that would have the solution of (3,6)
Answer:
Step-by-step explanation:
3x1=3
2x3=6
2+1=3
3+3=6
Two equations that have the solution (3,6) include y = 2x and x + y = 9, satisfying the point when their values are substituted.
To write two equations that would have the solution of (3,6), we need to construct linear equations where the point (3,6) satisfies both equations. Here are two examples that fit the criteria:
The first equation could be y = 2x, because when x=3, then y=2(3)=6.
The second equation could be x + y = 9, because when x=3 and y=6, then 3 + 6 = 9.
These two examples clearly have the solution (3,6) when the respective values for x and y are substituted.

A square orange rug has a yellow square in the center. The side length of the yellow square is x inches. The width of the orange band that surrounds the yellow square is 11 in. What is the area of the orange band?
To find the area of the orange band, subtract the area of the yellow square from the area of the larger square.
Explanation:To find the area of the orange band, we need to subtract the area of the yellow square from the area of the larger square. The side length of the larger square is 8 inches because it is twice the side length of the yellow square, which is x inches. So, the area of the larger square is 8 * 8 = 64 square inches. The area of the yellow square is x * x = x^2 square inches. Therefore, the area of the orange band is 64 - x^2 square inches.
Final answer:
To calculate the area of the orange band, find the area of the larger square using the side length of x + 22 inches and subtract the area of the smaller yellow square with side length x. The expression for the area of the orange band is [tex](x + 22)^2 - x^2[/tex], which simplifies to 44x + 484 square inches.
Explanation:
To calculate the area of the orange band, you need to determine the area of the outer (larger) square and subtract the area of the inner (smaller) yellow square. First, find the side length of the larger square, which is the side length of the yellow square plus twice the width of the orange band, so it's x + 2(11) inches. Thus, the side length of the larger square is x + 22 inches.
Now, calculate the area of both squares. The area of the larger square is [tex](x + 22)^2[/tex] square inches, and the area of the yellow square is [tex]x^2[/tex] square inches. The area of the orange band is the difference between these two areas:
Area of the larger square:[tex](x + 22)^2[/tex]
Area of the yellow square: [tex]x^2[/tex]
Area of the orange band: [tex](x + 22)^2 - x^2[/tex]
To find the area of the orange band, you expand the expression [tex](x + 22)^2[/tex], which gives you [tex]x^2 + 44x + 484[/tex], then subtract the area of the yellow square [tex]x^2[/tex], resulting in 44x + 484 square inches, which is the area of the orange band.

Harper went into a movie theater and bought 10 bags of popcorn and 6 drinks,
costing a total of $79. Damian went into the same movie theater and bought 3 bags of
popcorn and 5 drinks, costing a total of $36.50. Write a system of equations that
could be used to determine the price of each bag of popcorn and the price of each
drink. Define the variables that you use to write the system.
Answer:
The price of a drink = $4
The price of a bag of popcorn = $5.5
Step-by-step explanation:
Let p represent popcorn and d represent drink
Harper bought 10 bags of popcorn and 6 drinks and paid $79 ➡ 10p + 6d = $79
Damian bought 3 bags of popcorn and 5 drinks and paid $36.50 ➡ 3p + 5d = $36.50
Now multiply first equation by -3 and second equation by 10
-3 × (10p + 6d) = $79 ➡ -30p - 18d = -$237
10 × (3p + 5d) = $36.50 ➡ 30p + 50d = $365
Now add the new equationd
30p + 50d -30p - 18d = $365 - $237 (-30p will eliminate 30p)
32d = $128 divide both sides of the equation by 32
32 ÷ 32d = 32 ÷ $128 ➡ d = 4
If d = 4 that means a drink costs $4 we can use this information to find the price of a bag of popcorn
3p + 5d = $36.50 (replace d with 4)
3p + 4×5 = $36.50
3p + 20 = $36.50
3p = $36.50 - 20
3p = 16.50 divide both sides by 3
p = $5.5
The question asked to set up a system of equations to determine the price of each bag of popcorn and each drink. Using the variables x and y to represent the price of popcorn and drinks respectively, the system of equations based on the information given is 10x + 6y = $79 and 3x + 5y = $36.50.
Explanation:To solve this problem, we need to setup a series of equations based on the information given. Let's say:
x is the price of each bag of popcorny is the price of each drinkAccording to the first scenario with Harper, we get:
10x + 6y = $79
From Damian's shopping, we have:
3x + 5y = $36.50
This gives us the system of equations which can be used to find individual prices of a bag of popcorn and a drink.

It takes 2 1/5 kilometers of thread to make 2 5/6 boxes of shirts. How many kilometers of thread will it take to make 9 boxes of shirts.
It would take 6.99 kilometers of thread to make 9 boxes of shirts.
Step-by-step explanation:
Step 1; First we convert the mixed fractions into improper fractions. So
2[tex]\frac{1}{5}[/tex] becomes [tex]\frac{11}{5}[/tex] after multiplying 2 with 5 and adding 1 while 5 remains.
2[tex]\frac{5}{6}[/tex] becomes [tex]\frac{17}{6}[/tex] after multiplying the 2 with 6 and adding 5 while 6 remains.
Step 2; Next we equate the given data; [tex]\frac{11}{5}[/tex] kilometers of thread = [tex]\frac{17}{6}[/tex] boxes of thread. We must make the RHS equal to 1 to find out the kilometers of thread needed to make 1 box of shirts. So we multiply [tex]\frac{6}{17}[/tex] on both sides to make the RHS equal to 1.
[tex]\frac{11}{5}[/tex] × [tex]\frac{6}{17}[/tex] = [tex]\frac{17}{6}[/tex]× [tex]\frac{6}{17}[/tex]= 1, So [tex]\frac{11}{5}[/tex] × [tex]\frac{6}{17}[/tex] = [tex]\frac{66}{85}[/tex] km of thread. So [tex]\frac{66}{85}[/tex] kilometers of the thread is required to make 1 box of shirts so we multiply this with 9 to see thread required to make 9 boxes of shirts.
Thread required for 9 boxes of shirts = [tex]\frac{66}{85}[/tex] × 9= [tex]\frac{594}{85}[/tex] = 6.9882 kilometers of thread. This is rounded off to 6.99 kilometers of thread.
The number −6 is 2 more than an unknown number. Find the unknown number.
The unknown number is -8.
To find the unknown number, we can set up an equation based on the given information.
We are told that -6 is 2 more than the unknown number, so we can represent this as:
