What is the surface area of the figure? A. 408 ft2 B. 458 ft2 C. 545 ft2 D. 720 ft2

Answers

Answer 1

Answer: There are 2 faces 7 x 5

$2*(5*7)=2*35=70ft^2$

There 2 faces 5 x 5

$2*(5*5)=2*25=50ft^2$

there are 3 faces 5 x 12

$4*(5*12)=4*60=240ft^2$

There are 2 faces 7 x 7

$2*(7*7)=2*49=98ft^2$

Now only we have to sum all of them together

$98+240+50+70=458ft^2$

Angle QPS is supplementary to angle psr. Also QPS=(2x+12) and PSR is x. Find the value of x. Can you help

Answers

What does 'supplementary' mean ?
It means the two angles add up to 180 degrees.
So ...
      (2x + 12) + (x) = 180

Eliminate parentheses:    2x + 12   +   x   = 180

Add up the 'x' terms: 3x + 12    = 180

Subtract 12 from each side: 3x        = 168

Divide each side by 3 :    x        = 56 degrees

'of' can be translated to multiply so
1/4 times 12=12/4=3

she used 3 eggs
B is the answer

Answer:3

Step-by-step explanation:So 1/4and 12 is translated to multiply so you multiply 1/4x12=12/4=3 so its 3

In a chess match, a win counts as 1 point, a draw counts as 0.5 point, and a loss counts as 0 points. After 21 games between the two players, the winner was 8 points ahead of the loser. How many points did the winner have?PLS HELP

Answers

Answer:

14.5

Step-by-step explanation:

First, let's confirm that total points = total number of games played.

Suppose, if any one of the player wins all the games, then,

total points = 21(1) + 0 = 21 = total number of games

Suppose, all the games end in draw. Then,

21(0.5) + 21(0.5) = 21(0.5 + 0.5) = 21(1) = 21 = total number of games

Suppose, if one player wins in 10 games and the remaining 11 games end in draw, then,

10(1) + 11(0.5 + 0.5) = 10 + 11 = 21 = total number of games

So, in all cases, total points = total number of games played

Now, let x be the points that the loser has.

So, the winner's points should be x + 8.

Total number of games played = 21

Since, total points = total number of games played,

x + (x + 8) = 21

2x + 8 = 21

2x = 21 - 8 = 13

x = 6.5

Winner's points = x + 8 = 6.5 + 8 = 14.5.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of glasses of water the cooler can fill per minute be = A

Now , the equation will be

The number of glasses of water the cooler can fill = 150 glasses

The time required by the cooler to fill 150 glasses = 30 minutes

So , the equation is

The number of glasses of water the cooler can fill per minute = number of glasses of water the cooler can fill / time required by the cooler to fill 150 glasses

Substituting the values in the equation , we get

The number of glasses of water the cooler can fill per minute = 150 / 30

The number of glasses of water the cooler can fill per minute = 5 glasses

Therefore , the value of A is 5 glasses

Hence ,

The number of glasses of water the cooler can fill per minute is 5 glasses
