Which of the following equations have z = 4?
Select all that apply.
(A)9z + 22 = 26
(B)7z - 1= 27
(C) 46 - 8z = 14
(D) 5z + 40 = 62
Answer:
B and D
Step-by-step explanation:
7z -1 = 27 46 - 8z = 14
+1 +1 -46 -46
7z = 28 -8z = -32

Answer:
[tex]4* 10^{12}[/tex] (The 2nd one)
Step-by-step explanation:
You can do 6 ÷ 1.5.
This will give you 4.
If following the exponents rule, when dividing exponents with the same base, you need to subtract the exponents.
8 - (-4) = 12
6 is your base and 12 is your exponent.

What is the slope of a line perpendicular to the line whose equation is x - 3y = -18. Fully reduce your answer.
Given:
Equation of a line is
[tex]x-3y=-18[/tex]
To find:
The slope of the line perpendicular to the given line.
Solution:
The slope of the equation [tex]ax+by=c[/tex] is
[tex]Slope=-\dfrac{a}{b}[/tex]
We have,
[tex]x-3y=-18[/tex]
Here, a=1, b=-3. So, slope of this line is
[tex]m_1=-\dfrac{1}{-3}[/tex]
[tex]m_1=\dfrac{1}{3}[/tex]
Product of slopes of two perpendicular lines is -1.
Let slope of perpendicular line is [tex]m_2[/tex].
[tex]m_1\cdot m_2=-1[/tex]
[tex]\dfrac{1}{3}\cdot m_2=-1[/tex]
[tex]m_2=-3[/tex]
Therefore, the slope of the perpendicular line is -3.

Answer:
(a) b.
(b.) $85
Step-by-step explanation:
Answer:
Part A: B. 34/4 = e/10
Part B: Rachel can earn $85 in 10 hours.
Step-by-step explanation:
For Part A:
We know Rachel can earn $34 in 4 hours. We need to set up an equation so we know how much she can earn in 10 hours. 34/4 is on the left side of the equation, since we already know that. However, we don't know what e (earnings) is, so put that on the right over 10. Thus, the equation is 34/4 = e/10, which is B.
For Part B:
With the equation we just happened to figure out, cross multiply to find e.
34/4 = e/10
4e = 340
Divide both sides by 4
4e/4 = 340/4
e = 85
Rachel can earn $85 in 10 hours.
(Work Check:
34/4 = $8.50/hr
85/10 = $8.50/hr
These two values equal the same rate, so e as 85 is correct.)

∠A and ∠B\angle B ∠B are vertical angles. If m ∠A=(2x+7)∘\angle A=(2x+7)^{\circ} ∠A=(2x+7) ∘ and m ∠B=(5x+16)∘\angle B=(5x+16)^{\circ} ∠B=(5x+16) ∘ , then find the measure of ∠B\angle B ∠B.
Answer:
The answer is below
Step-by-step explanation:
An angle is defined as the figure formed by two rays meeting at a common end point. An angle is formed when two straight lines meet at a point. Angles are usually measured in degrees.
When two straight lines intersect, the pair of opposite angles formed is known as vertical angles (or vertical opposite angles). Vertical angles are equal to each other.
Given that ∠A and ∠B are vertical angles, therefore:
∠A = ∠B (vertical angles are equal)
2x + 7 = 5x + 16
2x - 5x = 16 - 7
-3x = 9
x = -3
∠B = 5x + 16
substituting x = -3:
∠B = 5(-3) + 16
∠B = -15 + 16
∠B = 1°

The mean length of a pine needle is 3.2 inches with standard deviation of .148 inches. What's the probability that a random sample of 44 needles has a mean over 3.5 inches
Answer:
0.02133
Step-by-step explanation:
We solve using the z score formula
z = (x-μ)/σ
where
x is the raw score = 3.5
μ is the population mean = 3.2
σ is the population standard deviation =0.148 inches
For x > 3.5
z = 3.5 - 3.2/0.148
z = 2.02703
Probability value from Z-Table:
P(x<3.5) = 0.97867
P(x>3.5) = 1 - P(x<3.5)
P(x>3.5) = 1 - 0.97867
P(x>3.5)= 0.02133
The probability that a random sample of 44 needles has a mean over 3.5 inches is 0.02133

simplify the expression 4p-5p-30p=
Answer:
-31p
Step-by-step explanation:
The simplified form of the expression 4p - 5p - 30p is -31p.
The given expression is,
4p-5p-30p
Expressions are simplified when they are rewritten in a concise manner and without any similar phrases. When we combine similar terms in an expression and, if necessary, solve all of the specified brackets, we are only left with unlike terms in the simplified expression that cannot be further reduced.
Combine like terms,
We have three terms with the variable p.
Combining them, we get -p - 30p, which simplifies to -31p.
Mathematically we can write,
(4-5-30)p
= (-1-30)p
= -31p
Therefore, the simplified form of the expression 4p - 5p - 30p is -31p.

Which angle has the greatest measure?
Answer:
It's G
Step-by-step explanation:
It has an acute angle while two of the other answers are vertical angles & the other answer choice is obtuse
The angle 12 has the greatest measure than the angle 5,7 and angle 8 option (F) ∠12 is correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
From the figure
The angle 5 and angle 7 are vertically opposite angles.
The angle 8 is an acute angle which is less than 90 degree.
The angle 12 is an obtuse angle which is greater than 90 degree.
Thus, the angle 12 has the greatest measure than the angle 5,7 and angle 8 option (F) ∠12 is correct.
