will someone help me work through this problem, please

First of all I wanna point out a minor mistake!

this is not a rectangular prism, the base of this picture is actually the side facing us and the back side. Making this a triangular prism.

We can start by finding the 2 triangles which are the bases.

Each triangle have area:10*24/2

Now because there are 2 same triangles we can get rid of the /2 and get the area of the triangles in the diagram is 10*24=240

We could do the other three sides 1 by 1, let's start with the side on the left of the shape. It has area 24*19=456 because the bottom is a rectangle so we could just use the 19.

Now we can do the side that is diagonal and on the right. It has area of 26*19=494.

Now just 1 more side the bottom, it has area of 10*19=190. Everything is in cm^2 as a unit because we are dealing with area.

Now we just need to add everything together.

240+456+494+190= 1380

Hope it helps! any questions about my answer please just leave in the comment I will get to it when I have time.

Answer:

your answer is 1380

Answer: 14500

Step-by-step explanation:

Let the price of the mobile phone before the GST was added be represented by x.

Therefore,

x + (12% × x) = 16240

x + 0.12x = 16240

1.12x = 16240

x = 16240/1.12

x = 14500

The price of the mobile phone before the GST was added was 14500

Answer:

A. 3*6-4-4

Step-by-step explanation:

He starts with 3 rows of 6 eggs, which can be shown in the formula 3*6, and each time he is taking away 4 eggs and hew does that twice so the only logical explanation is A. 3 x 6 - 4 - 4.

Answer:

v=-12

Step-by-step explanation:

-8=v+4

-4     -4

-12=v

Answer:

v = -12

Step-by-step explanation:

We have the equation v + 4 = -8

Subtract 4 from both sides.

v + 4 - 4 = -8 - 4

+4 and -4 cancel one another out.

We get v = -12.

Answer:

[tex]\boxed {\boxed {\sf 2 \ real \ solutions }}[/tex]

Step-by-step explanation:

The quadratic formula is:

[tex]{x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex]

The discriminant of a quadratic is just the expression under the square root, or [tex]b^2-4ac[/tex]. This can tell us the number of solutions a quadratic has.

If the discriminant is:

Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

Answer:

75

Step-by-step explanation:

they gave u 105 it is parallel to the line above it so u add them

105+105=210

then u subtract with 360 which forms a full angle

then u get 150

now u got the total of 2 angles so u divide them with2 to get 1 angle

then the answer is going to be 75

Answer:

B.) 42.9

Step-by-step explanation:

The percent that we are trying to find out is 12/28

I know this because if you add the 12 and 16 which is the total amount of people given then it leaves us with an amount of 28 people. Since we are trying to find the percent of the number of people who like fish we have to divide the total by 12 (the number of people who like fish)

Anyways 12 divided by 28 = 42.857etc.

If we simplify this then that gives us our answer of B.) 42.9

Answer:

2 and 4 I am pretty sure. hopeful that's correct.

Answer:

For the inequality to be true, both factors must have the same sign or one factor must be 0. The zeroes occur at x = − 2 , x = 5 . Thus, our intervals will be ( − ∞ , − 2 ] , [ − 2 , 5 ] , [ 5 , ∞ ) Take a sample point from each. A sample point of − 3 for the first interval yields ( − 3 + 2 ) ( − 3 − 5 ) = ( − 1 ) ( − 8 ) = 8 , so the first interval satisfies the inequality. Choosing a sample point of x = 0 for the second interval, we receive ( 2 ) ( − 5 ) = − 10 , so this interval will not satisfy the equality. A sample point of x = 6 for the third interval gives us ( 8 ) ( 1 ) = 8 , so the third interval satisfies. Thus, the domain that satisfies the inequality is ( ∞ , − 2 ] & [ 5 , ∞ ) On the number line , you would draw and fill in a circle above -2, and draw an arrow from that point to the left. You would then draw and fill in a circle above 5, and provide a similar arrow to the right (i.e. towards positive infinity). We fill in these circles because the intervals are closed at these points, i.e. these points satisfy the inequality. If we instead had ( x + 2 ) ( x − 5 ) > 0 , the circles would be empty because those points would not satisfy.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let 'x' be the original price.

x + 39% of x = 197.38

x + 0.39 x   = 197.38

1.39x  = 197.38

      x = 197.38/ 1.39
