Which ordered pair is in the solution set of y > 1/2x + 10?
Answer:
D
Step-by-step explanation:
Substitute the x and y values of each answer option. If y is greater than or equal to half of x plus 10, the answer is correct.
In the last option, if you substitute the x value, -2, into 1/2x + 10, the result is 9. The y value is 11, which is greater than or equal to 9, so the last one is the correct answer.

Evaluate the expression when c = 6 and x = -2.
c-6x
Answer:
18
Step-by-step explanation:
C = 6 and x = -2 just mean that you are supposed to substitute them into the equation.
That means that the equation should be: 6 - 6 * -2, or 6 − 6 (−2), or 18.

Joshua and Kay are out for a walk on a
rainy day. They come to the edge of a large,
circular puddle that has a radius of 3 feet.
Joshua is wearing boots, so he walks straight
through the center of the puddle to the
other side. Kay forgot to wear her boots, so
she walks around the outside of the puddle
to meet Joshua on the other side.
How much farther, in feet, did Kay walk
than Joshua? (Use 3.14 for π.)
Answer:
3.42 feet
Step-by-step explanation:
Joshua walked 3 x 2 = 6 feet
Kay walked approximately (3.14 x 6)/2 or 9.42 feet
9.42 - 6 = 3.42 feet
Kay walked 3.42 feet further than Joshua.

Which of the following expressions is equivalent to the logarithmic
expression below?
In 5 + In 3
Answer:
Ln 15
Step-by-step explanation:
The expression equivalent to ln(5) + ln(3) is logarithmic ln(15), which is option C.
What are the properties of logarithms?There are four basic properties of logarithms:
logₐ(xy) = logₐx + logₐy.
logₐ(x/y) = logₐx - logₐy.
logₐ(xⁿ) = n logₐx.
logₐx = logₓa / logₓb.
Given expression,
In 5 + In 3
We can use the logarithmic identity that says:
log(x) + log(y) = log(xy)
Using this identity, we can rewrite the given expression as:
ln(5) + ln(3) = ln(5 × 3) = ln(15)
Option A, ln(5³) is equivalent to ln(125), which is not the same as ln(15).
Option B, ln(8) is not equivalent to ln(5) + ln(3).
Option D, ln(3⁵) is equivalent to ln(243), which is not the same as ln(5) + ln(3).
Therefore, the expression equivalent to ln(5) + ln(3) is ln(15), which is option C.

Use technology or a z-score table to answer the question.
The weights of books in a bookcase are normally distributed with a mean of 11.6 pounds and a standard deviation of 1.3 pounds. There are 136 books on the bookshelf.
How many of the books will weigh 10 pounds or more?
A. 109
B. 116
C. 121
D. 130
The number of books that will weigh 10 pounds or more is 121. Then the correct option is C.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The weights of books in a bookcase are normally distributed with a mean of 11.6 pounds and a standard deviation of 1.3 pounds. There are 136 books on the bookshelf.
Then the z-score when the books will weigh 10 pounds or more will be
[tex]z = \dfrac{10 - 11.6}{1.3}\\\\z = -1.23077[/tex]
Then the probability will be
[tex]\rm P(x > 10) = 1 - P(x < 10) = 0.8909 \ or \ 89.09\%[/tex]
89.09% of books will weigh 10 pounds or more, then the number of the books will be
→ 136 × 0.8909
→ 121.1624 ≈ 121

Find the value of x
Answer:
Step-by-step explanation:
The sum of the interior angles of this triangle must be 180 degrees.
Thus, angle x is 180 degrees less (39 degrees plus 125 degrees), or
x = 180 degrees - 164 degrees = 16 degrees.
Because of the 125 degree angle, this is an obtuse triangle.

find the value of p
1) p=7
2) p=20
3) p= 145
4) p=75
Answer:
p= 20
Step-by-step explanation:
360 - 145 -75 = 7p
140 =7p
140 ÷7 =7p ÷7
20 = p
Answer:
p= 20°
Step-by-step explanation:
here's your solution
==> Angle formed around a point = 360°
==> 145° + 75° + 7p° = 360°
==> 220° + 7p° = 360°
==> 7p° = 360° - 220°
==> 7p° = 140°
==> p = 140°/7
==> p= 20°
