Answer:
2 and -5
4c and 7c
Step-by-step explanation:
2 and -5 have no coefficient
4 and 7 have the same coefficient which in this case is c.
therefore the two pairs are like terms.
Maya’s chocolate is 59% cocoa. If the weight of the Chocolate bar is 93 grams, how many grams cocoa does it contain? Round your answer to the nearest tenth.
Answer:
54.9 because it is the answer
Answer:
= 54.9g
Step-by-step explanation:
You must find 59% of 93g
50% = 46.5g
1% = 0.93g
9% = 8.37g
46.5+8.37=54.87g
rounded = 54.9g

Answer:
9/25
Step-by-step explanation:
Use the given information to find the minimum sample size required to estimate an unknown population mean μ.
How many students must be randomly selected to estimate the mean weekly earnings of students at one college? We want 95% confidence that the sample mean is within $4 of the population mean, and the population standard deviation is known to be $25.
Answer:
151 students must be selected.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
The population standard deviation is known to be $25.
This means that [tex]\sigma = 25[/tex]
How many students must be randomly selected to estimate the mean weekly earnings of students at one college? Sample mean within $4 of the population mean
This is n for which M = 4. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]4 = 1.96\frac{25}{\sqrt{n}}[/tex]
[tex]4\sqrt{n} = 1.96*25[/tex]
[tex]\sqrt{n} = \frac{1.96*25}{4}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96*25}{4})^2[/tex]
[tex]n = 150.1[/tex]
Rounding up:
151 students must be selected.

Step-by-step explanation:
the volume of 12 buckets is the same as the volume of 9 bottles. the total volume of 3 bottles and 5 buckets is 21.6 liters. what is the volume of 1 bucket?
Answer:
The volume of 1 bucket is 2.4 liters.
Step-by-step explanation:
We know that the volume of 12 buckets is the same as the volume of 9 bottles:
[tex] 12B = 9b [/tex]
[tex] B = \frac{9}{12}b = \frac{3}{4}b [/tex] (1)
Where B is for buckets and b is for bottles.
Also, that the total volume of 3 bottles and 5 buckets is 21.6 liters:
[tex] 5B + 3b = 21.6 [/tex] (2)
We can calculate the volume of 1 bucket by entering equation (1) into (2):
[tex] 5(\frac{3}{4}b) + 3b = 21.6 [/tex]
By solving for "b" we have:
[tex] b = \frac{21.6*4}{27} = 3.2 [/tex]
Now, the volume of 1 bucket is:
[tex] B = \frac{3}{4}b = \frac{3*3.2}{4} = 2.4 [/tex]
Therefore, the volume of 1 bucket is 2.4 liters.
I hope it helps you!
Find the distance from A to C across the gorge illustrated in the figure.
The distance from A to C is ___ feet.
Step-by-step explanation:
tan B = AC/BC
tan 35°= AC / 160
0.700 = AC /160
=> AC = 160 × 0.700
AC = 112.00
so, the distance from A to C is 112.00 feet
From the triangle given in the figure,
ΔACB is a right triangle.Measure of angle ABC = 35°Measure of adjacent side BC = 160 ftSince, adjacent side BC of the right triangle ACB is given and we have to find the opposite side AC of angle ABC,
Trigonometric ratio to be used → [tex]\text{tan}\theta = \frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
By substituting these values in the expression,
[tex]\text{tan}(35^{\circ}) = \frac{AC}{160}[/tex]
AC = 160[tan(35)°]
AC = 112.03 feet
Therefore, distance between A and C is 112.03 feet.

3. What is the measure of remote angle, LA?
80
B
Answer:
m<A = 40°
m<C = 113°
Step-by-step explanation:
Problem 1:
m<A = ½(arc BC) (Inscribed angle theorem)
Substitute
m<A = ½(80°)
m<A = 40°
Problem 2:
Given that m<A = 67°
Recall: angels that are opposite each other in any given inscribed quadrilateral are supplements of each other.
Thus, it implies that:
m<A + m<C = 180°
Substitute
67° + m<C = 180°
Subtract 67° from each side
m<C = 180° - 67°
m<C = 113°

The sum of the measures of the angles of a triangle is 180 deg.
m<E + m<F + m<G = 180
m<E + 75 + 45 = 180
m<E + 120 = 180
m<E = 60

solve these equations, show all your work x-2=10 and x+6=13
Answer:
x = 12 , x = 7
Step-by-step explanation:
x-2 = 10
x= 10+2 = 12
x+6 = 13
x=13-6
x=7
Answer:
x = 9.5
If they were separate equations,
x - 2 = 10 ⇒ x = 12
x + 6 = 13 ⇒ x = 7
Step-by-step explanation:
x - 2 + x + 6= 10 + 13
2x + 4 = 23
2x + 4 - 4 = 23 - 4
2x = 19
2x ÷ 2 = 19 ÷ 2
x = 9.5
If they were separate,
x - 2 = 10
x - 2 + 2 = 10 + 2
x = 12
x + 6 = 13
x + 6 - 6 = 13 - 6

Suppose that the function y = f(x) is decreasing on the interval ( 5, 7). What can be said about the graph of y= -f(x)
The graph of y = -f(x) is increasing on the interval ( 5, 7) if the function y = f(x) is decreasing on the interval ( 5, 7).
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
Suppose that the function y = f(x) is decreasing on the interval ( 5, 7).
The function:
y = -f(x)
Let f(x) be:
f(x) = -aˣ
Here 'a' is the real number a > 0
f(x) is decreasing on the interval ( 5, 7).
Applying transformation:
y = -f(x)
y = aˣ
Function y is increasing on the interval ( 5, 7).
Thus, the graph of y = -f(x) is increasing on the interval ( 5, 7) if the function y = f(x) is decreasing on the interval ( 5, 7).

I think the answer would be b. Ariel, Amber, and Ethel because if you look at the vertical lines that are going up and down, you can count that there are 6 boxes colored in and that there are 4 left uncolored.
Step-by-step explanation:
The 6 boxes acts as the 60% and the 4 acts as 40%. If you add them together, you would get 100%. Ethel also has a horizontal line going down the center of his boxes, which makes his numbers doubled, but he still has 60% colored in. Ariel only has 5 boxes in total and 3 if them colored in, but the 3 are still 60% and the 2 uncolored are 40%. If you were to divide every box onto 2, you would end up with 10 in total, 6 colored in, and 4 uncolored.

y = 3/5x + 5
y = -3/5x + 5
y = 3/5x - 5
y = -3/5x - 5
Answer:
y= 3/5x+5
Step-by-step explanation:
The y intercept is 5 and the graph is going upwards so it is a postive slope. If you look at at the graph from the y intercept point to point B you can see it goes up by 3 and right by 5 so the slope is 3/5. This makes the equation y=3/5x+5
