1 answer:

3 0

Right, AB would be a ray starting at 'a', passing through 'b', and continuing on past 'b'. BA would be a ray starting at 'b', passing through 'a', and continuing on past 'a'.

The two rays share only the line segment ab. They do NOT share the direction of travel.

ExtremeBDS [4]

Answer:

$93\frac{3}{20} \ square \ inches$ .

Step-by-step explanation:

Given:

Maggie has 4 3/5 container of icing to decorate cakes for a bake sale.

Each container will cover 20 1/4 square inches.

Question asked:

How many square inches will it cover if she uses all of her icing ?

Solution:

Total number of container Maggie has = $4\frac{3}{5}$

Each container will cover = $20\frac{1}{4}$ square inches.

Now, we can find easily that how many square inches it will cover by using all of her icing by unitary method:

Each container will cover = $20\frac{1}{4}$

$4\frac{3}{5}$ container will cover = $20\frac{1}{4}\times4\frac{3}{5} =\frac{20\times4+1}{4} \times\frac{5\times4+3}{5} \$

$=\frac{81}{4} \times\frac{23}{5} =\frac{1863}{20} =93\frac{3}{20}\ square\ inches$

Thus, it will cover $93\frac{3}{20} \ square \ inches$ ,if she uses all of her icing.

5x - 3 = 11 + 12x

---Subtract 5x from both sides

-3 = 11 + 7x

---Subtract 11 from both sides

-14 = 7x

---Divide both sides by 7 to leave x by itself

x = -2

Answer: x = -2

Answer Choice: A, -2

Suppose the mean percentage in Algebra 2B is 70% and the standard deviation is 8% What percentage of students pass the class wit

AlekseyPX

Answer:

Z-value is what we called the number of standard deviations from the mean. 62% is 8% one standard deviation to the left, or a Z-value of -1. 94 is 24% to the right of the mean, or 3 standard deviations for a z-value of three. You can look on a Z-table to find the area between -1 and 3, which is .840 or 84%
