7/100 = 0.07

0.07 * 12.5 = 0.88

20/100 = 0.2

0.2 * 12.5 = 2.5

2.5 + 0.88 = 3.38

3.38 + 12.50 = 15.88

You spend a total of $15.88.

Given 2 and 1 over 10 times negative seven times 5 over 12, determine the product.

yKpoI14uk [10]

The solution to the algebra 2 and 1 over 10 times negative seven times 5 over 12 is; negative six and 1 over 8

<h3>How to Multiply Fractions?</h3>

2 and 1 over 10 times negative seven times 5 over 12 can also be expressed as; 2¹/₁₀ * ⁽⁻⁷ * ⁵⁾/₁₂

Multiplying out the bracket gives;

²¹/₁₀ * -³⁵/₁₂

Dividing by common factors gives;

= ⁷/₂ * ⁻⁷/₄

= -49/8

= -6¹/₈

This can also be written as negative six and 1 over 8

Thus, we conclude that the solution to the algebra 2 and 1 over 10 times negative seven times 5 over 12 is; negative six and 1 over 8

Step-by-step explanation:

just think back to the standard circle of radius = 1.

there the trigonometric functions are all represented as sides of right-angled triangles, where the radius is the baseline.

just like the triangle we are seeing here.

the only difference : the baseline (radius) is 17 and not 1.

and that is fine. everything is as in the standard circle, but multiplied by the radius (which is also true for the standard circle, but multiplying by 1 does not change anything, right ?).

angle A is or focus. so, just imagine the triangle turned counterclockwise by 90° (so that AC is horizontal and CB is vertical).

do you see it now ?

sin is the vertical leg, cos the horizontal leg. and the leg lengths here are the standard functions multiplied by the radius.

so,

17 × sin A = 8

sin A = 8/17 = 0.470588235... ≈ 0.47

17 × cos A = 15

cos A = 15/17 = 0.882352941... ≈ 0.88

now B is our focus. imagine the triangle being mirrored at point B, so that B is left, and AC is right. your see it now ?

tan B = sin B / cos B

sin B = 15/17 = 0.882352941... ≈ 0.88

cos B = 8/17 = 0.470588235... ≈ 0.47

tan B = 15/17 / 8/17 = 15/8 = 1.875 ≈ 1.88

cos B = 8/17 = 0.470588235... ≈ 0.47

Bryce measured a picnic area near the river and made a scale drawing. The scale of the

photoshop1234 [79]

Answer:

112 inches

Step-by-step explanation:

First since we are dealing with scale factor here you are going to want to divide the 48 by 3 since they are both written with yards.

After dividing you will get 16. This is how times you are going to multiply scale factor by. You then multiply 16 by 7 to get 112 inches as your answer.

Determine whether 81a2 − 25z6 is a difference of two squares. If so, factor it. If not, explain why.

aev [14]

81 a² - 25 $z^{6}$ is a difference of two squares and its factors are (9a + 5z³) and (9a - 5z³)

Step-by-step explanation:

The difference of two squares is a binomial of two terms each term is a square and the sign between the two terms is (-), its factorization is the product of two identical binomials with different middle signs
