Can someone help me please

Answer:

1. b  2.a  3c

Step-by-step explanation:

The sides that correspond to each angle in triangle ABC are:

Angle XYZ corresponds with side length YZ

Angle ZXY corresponds with side length XZ

Angle YZX corresponds with side length YX

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Since, We know that;

The corresponding sides are segments located at the same relative position of an angle.

So, the corresponding sides of the angles are:

Side YZ & angle XYZ,

Side XZ & angle ZXY,

And, Side YX and angle YZX

Thus, The sides that correspond to each angle in triangle ABC are:

Angle XYZ corresponds with side length YZ

Angle ZXY corresponds with side length XZ

Angle YZX corresponds with side length YX

The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.

Step-by-step explanation:

Answer:

D) 472

Step-by-step explanation:

Surface Area formula:

SA = 2(wl + hl + hw)

Given:

w = 7

l = 12

h = 8

Work:

SA = 2(wl + hl + hw)

SA = 2(7 x 12 + 8 x 12 + 8 x 7)

SA = 2(84 + 96 + 56)

SA = 2(236)

SA = 472

Answer:

\((7a \cdot 5b) \div 6c \cdot 2d\)

Step-by-step explanation:

If there is both multiplication and division in an expression and no parentheses, you start solving from left to right. Since in the expression \(7a \cdot 5b \div 6c \cdot 2d\) you would start by solving \(7a \cdot 5b\), (because it's at the leftmost part of the expression) it won't matter whether you put parentheses around \(7a \cdot 5b\) or not. Therefore, the expression \((7a \cdot 5b) \div 6c \cdot 2d\) is equivalent to \(7a \cdot 6b \div 6c \cdot 2d\).

The melting point of zinc is (420-98) = 322 degrees Celsius hotter than the melting point of sodium.

The temperature of Venus is (480 - (-230)) = 710 degrees Celsius warmer than the temperature on Pluto.

The difference between the melting points of aluminum and copper is (1083 - 659) = 424 degrees Celsius.

The boiling point of water is (212 - (-440)) = 652 degrees Fahrenheit hotter than the boiling point of propane.

The difference between the freezing points of unleaded gas and water is (-150 - 32) = -182 degrees Fahrenheit.

The difference in temperature between the day side and dark side of Mercury is (400 - (-180)) = 580 degrees Celsius.

Hydrogen freezes first because it has a lower freezing point (-252.80C). To freeze oxygen, the temperature needs to be lowered to (-218.79C).

The temperature dropped (10 - (-9)) = 19 degrees Celsius.

The drop in temperature from day to night on the moon is (260 - (-280)) = 540 degrees Fahrenheit.

The melting point of gold is (1946 - 1762) = 174 degrees Fahrenheit hotter than the melting point of silver.

Answer: The melting point Zinc is 420 - 98, which equals 322 degrees. The Celsius is hotter than the melting point of sodium.

Answer:

y-int = 6

x-int = -3

Step-by-step explanation:

1.) y-int is found by setting x = 0

-2(0) + y = 6

y = 6

2.) x-int is found by setting y=0

-2x + (0) = 6

-2x = 6

divide by -2 on each side

x = -3

Answer:

   The original length of the board is 8 feet.

   The length that was cut off is 2 feet.

   One possible equation we can use is: x = 8 - 2, where x represents the length of the board that is left. Solving for x, we get x = 6 feet.

   The length of the board that is left is 6 feet.

Step-by-step explanation:

We are given that the board was originally 8 feet long. Bryce cuts off 2 feet from the board to use for a project. Therefore, the length of the board that is left is 8 - 2 = 6 feet.

To solve this problem algebraically, we can set up an equation where x represents the length of the board that is left. We know that the original length of the board is 8 feet, and 2 feet was cut off, so we can write:

x = 8 - 2

Simplifying this equation gives us:

x = 6

Therefore, the length of the board that is left is 6 feet.

Answer:

11.2$

Step-by-step explanation:

Kristina and Melissa had 32$ at total

● 32$ => 100%

They have spent 35%

Let x be that amount

● x => 35%

●32 => 100

● x => 35

● x = (35×32)/100 = 11.2$

They have spent 11.2$

Answer:

They spent $20.80

Step-by-step explanation:

Since they had $32 and spent 35% of it you would do 32 * 35%

 then you would get 11.2

now that is not the answer because that is just what 35% of 32 is

to get the answer you would then subtract 11.2 from 32 to get 20.8

and since this is a matter of money you would write 20.8 as $20.80.

Answer:

x = 4 and y = 6

Step-by-step explanation:

With the way the equations are set up, substation is faster.

Just substitute -1/2x + 8 for the y in the first equation.

3x + 4(-1/2x + 8) = 36

And then you can just solve the equation. You would get x = 4.

Substitute 4 for x.

y = -1/2(4) + 8

y = 6

Step-by-step explanation:

Answer:

45

Step-by-step explanation:

The Allstars team has the higher mean and median compared to Champs team. Therefore, the Allstars has the tallest players.

By using mean and median, we can know which team typically has the tallest players

For the Allstars:

Mean: The mean height of the Allstars team is obtained by summing up all the heights and dividing by the total number of players:

Mean = (73 + 62 + 60 + 63 + 72 + 65 + 69 + 68 + 71 + 66 + 70 + 67 + 60 + 70 + 71) / 15 ≈ 67.1 inches

Median: The median height of the Allstars team is the middle value when the heights are arranged in ascending order:

Arranging the heights in ascending order: 60, 60, 62, 63, 65, 66, 67, 68, 69, 70, 70, 71, 71, 72, 73

Median = 68 inches

For the Champs:

Mean: The mean height of the Champs team is obtained by summing up all the heights and dividing by the total number of players:

Mean = (62 + 69 + 65 + 68 + 60 + 70 + 70 + 58 + 67 + 66 + 75 + 70 + 69 + 67 + 60) / 15 ≈ 66.4 inches

Median: The median height of the Champs team is the middle value when the heights are arranged in ascending order:

Arranging the heights in ascending order: 58, 60, 60, 62, 65, 66, 67, 67, 68, 69, 69, 70, 70, 70, 75

Median = 67 inches

The Allstars team typically has the tallest players. The mean height of the Allstars team is about 67.1 inches, while the mean height of the Champs team is about 66.4 inches. Additionally, the median height of the Allstars team is about 68 inches, while the median height of the Champs team is about 67 inches. Both the mean and median heights of the Allstars team are higher, indicating that, on average, the Allstars team has taller players compared to the Champs team.

Answer:

The number of monthly calls for which Plan 1 is more economical than Plan 2 is 200 calls If more than 200 calls are made, the plan 1 charge will be more than plan 2. Let the number of charges per month be x  If plan 2 charges ​$16 per month plus ​$0.04 per call, this is expressed as 0.04x + 16  Price that pan 1 charges = $24  If Plan 1 is more economical than Plan 2, this is expressed as:0.04x + 16 > 24 Subtract 16 from both sides:0.04x + 16 - 16 > 24 - 16   0.04x > 8 x = 6/0.04 x = 200 This shows that if more than 200 calls are made, the plan 1 charge will be more than plan 2.
