Here are sketches of four triangles.

Mathematics
1 answer:
baherus [9]3 years ago
7 0

Answer:

3.4

Step-by-step explanation:

If we look at the top left triangle and the triangle with x, we notice that they are similar (since they have a 57° and a right angle). This means that 4 / 1 = x / 0.84, which means that x = 3.4.

One serving of a certain brand of yogurt contains 12 G of fat the low-fat version contains 38.75% less fat per serving how many
Mkey [24]

Answer:

One serving of law-fat yogurt contains 7.35 g of fat.

Step-by-step explanation:

One serving of

  • a certain brand of yogurt contains 12 g of fat
  • the low-fat yogurt contains 38.75% less fat

Let x g be the amount of fat in low-fat yogurt. Then

12 g of fat - 100%

x g of fat - 100% - 38.75% = 61.26%

Write a proportion

\dfrac{12}{x}=\dfrac{100}{61.25}

Cross multuply

100\cdot x=12\cdot 61.25\\ \\100x=735\\ \\x=\dfrac{735}{100}=7.35

One serving of law-fat yogurt contains 7.35 g of fat.

Anybody know the right answer?
Murljashka [212]
Y = -1 is a horizontal line going through "-1" on the y axis

Note that the point (1,2) is exactly 3 units of distance above the line y = -1

When we reflect across this line, the point (1,2) will just move straight down to exactly 3 units of space below the line y = -1.  Since we are not shifting left or right, the x coordinate of our original point will not change.  The y coordinate of our original point will now need to be reduced by 6(3 units down to get to the line of reflection and then 3 more down to get to the image location)   

The coordinates of the image point will be (1, -4)
Now we need to do the same process with (1, -4) being reflected across y=1

Note (1,-4) is 5 units of distance below the line y = 1 , so we need to reflect the point upward so that the image point is located exactly 5 units of distance above the line y = 1  Again, the x coordinate does not change, and our final image coordinates are (1, 6)

I guess more simply stated, if you're just looking for the number in the green box it would be " 1 " .. Reflecting points across horizontal lines only result in changes of the "y" coordinate since there is no shift left or right.

PLEASE HELP !! IT WOULD BE GREATLY APPREACIATED ! I DONT KNOW HOW TO DO THIS
serg [7]

(A) Bella's TV ratio of sides: 36"/27" = 1.333...

Lenny's: 52"/29.25" = 1.777...

Bella's and Lenny's TVs are NOT similar - their side ratios are different. Bella's is 4:3 while Lenny's is close to 16:9.

(B) Bella's TV has an exact ratio of 4:3 (36/27=4/3) and so is the older type.

Lenny's TV has a ratio of 52"/29.25". Divide both 52 and 29.25 by 3.25 to get 16/9, or 16:9. So Lenny's is the newer type.
