<span>The chance or probability that the lawn mower will hit a piece of glass that is already cracked is calculated by dividing the number of glasses that are cracked by the total number of glasses. In this item, the unknown can be calculated by 3/15. The answer is therefore, 1/5 or 0.20. </span>

The radius of circle G is 4 cm. What is the tangent
qaws [65]
The tangent of a given circle is perpendicular to the radius a the point called point if tangency. The radius of the circle is perpendicular to the tangent at the point of tangency. This property is especially useful in cases where the radius that connects to the point of tangency forms a part of right angle because the pythagorean theorem and trigonometry apply to right angles.

GalinKa [24]
The correct question is
<span>Javier is making a cake for a party. The recipe calls for 2 3/4 cups of flour, but he wants to triple the recipe. He guessed and put in 7 cups of flour. How many more cups of flour should he have used?

we know that
2 3/4 cups of flour------> (2*4+3)/4----> 11/4 cups
if he </span>wants to triple the recipe------> 3*(11/4)----> 33/4 ----> 8 1/4 cups required

8 1/4-7=1 1/4 cups

the answer is
1 1/4 cups

Which expression has a negative value?
Igoryamba

Answer:

A: 7 + 3 (negative 4) (2)

Step-by-step explanation:

Just as a rule of thumb, whenever you multiply or divide one negative number and one positive number, the outcome is always negative. However, whenever you multiply or divide two negative numbers OR two positive numbers, the outcome is always positive.

Now, let's first convert all these words into simple mathematical expressions and then solve them:

A) "7 + 3 (negative 4) (2)" = 7 + 3 * (-4) * 2 = 7 + (-24) = -17

B) "Negative 2 Left-bracket 12 divided by (negative 3) Right-bracket" =

-2 * [12/(-3)] = -2 * (-4) = 8

C) "(15 minus 7) minus (9 divided by 3)" = (15 - 7) - (9/3) = 8 - 3 = 5

D) "Negative 5 Left-bracket 7 + (negative 14) Right-bracket minus 30" =

-5 * [7 + (-14)] - 30 = -5 * (-7) - 30 = 35 - 30 = 5

The only expression that produces a negative value is the first one, A.

Hope this helps!
