Answer:
x = 119
z = 28
Step-by-step explanation:
To find x: Because of same-side exterior angles, you can add x and 61 together to find 180 degrees.
x + 61 = 180
Subtraction: x = 119
To find z: Use given quantities, not found variables for most accurate answer. Because of opposite exterior angles, you can equal them to each other.
61 = 5z - 79
Addition: 140 = 5z
Division: 140/5 = 5z/5
Final Answer = 28 = z
Last year, 12 hydrange bushes had a mean of 14 blooms each, with a standard deviation of 2. The dot plot shows the number of blooms on the same bushes this year after a new plant food is used. What conclusions can you draw about the use of the new plant foor and the number of blooms?
Answer: The plant food produces more blooms on average, but the results aren't as consistent as before.
========================================
Explanation:
The dot plot leads to this data set
{8, 12, 12, 17, 17, 18, 18, 18, 19, 19, 20, 23}
Using pencil/paper, or using technology, you should find the following properties of this data set
mean = 16.75sample standard deviation = 4.11The second value is approximate. Both the mean and standard deviation are larger than their original counterparts (mean = 14 and std dev = 2).
Since the mean is larger, this means the data points have been shifted to the right further. The larger standard deviation tells us that the data is more spread out.
So it appears this new plant food has made the number of blooms increase overall, but it's also made the data more inconsistent. A smaller standard deviation would mean a more narrow set of points and therefore more consistent values (they'd all be clumped around the mean better).

What value of x makes the equation below true 6x-7=26
Answer:
11/2
Step-by-step explanation:
6x−7=26
Step 1: Add 7 to both sides.
6x−7+7=26+7
6x=33
Step 2: Divide both sides by 6.
x= 11/2

The distance from Cherotich's home to school is
2km 400m. He goes to school in the morning
and returns in the evening daily. What distance
does he cover from Monday to Friday?
Answer:
24 kilometers
Step-by-step explanation:
Given
Represent the distance with x
[tex]x = 2km\ 400m[/tex]
Required
The distance covered for 5 days (i.e. Monday to Friday)
First, we calculate the distance covered in a day
He covers the same distance when going to school and when coming back from school.
So, the daily distance is:
[tex]Daily = 2 * x[/tex]
[tex]Daily = 2 * (2km\ 400m)[/tex]
[tex]Daily = 4km\ 800m[/tex]
In 5 days, he covers:
[tex]5\ days = 5 * Daily[/tex]
[tex]5\ days = 5 * (4km\ 800m)[/tex]
[tex]5\ days = 5 * (4km+ 800m)[/tex]
Open bracket
[tex]5\ days = 5 * 4km+ 5 * 800m[/tex]
[tex]5\ days = 20km+ 4000m[/tex]
Convert m to km
[tex]5\ days = 20km+ 4km[/tex]
[tex]5\ days = 24km[/tex]

Bags of sugar come in 3 sizes:
Small bag: A 250 g bag costs 85p.
Medium bag: A 500 g bag costs £1.90.
Large bag: A 3 kg bag costs £3.90.
Calculate the cost of 3 kg for the small and medium bags.
Give your answer in pounds to 2 dp.
Write the bag that is the better value in the comments.
Answer:3kg of small bag costs £10.20 while 3kg of the medium bag costs £11.40. Hence, the bag with better value which is the cheapest is a 3kg of the big bag which costs £3.9

Find the solution set of the inequality
5x + 13 > -37.
x ?
Answer:
x > -10
Step-by-step explanation:
5x + 13 > -37
subtract 13 from each side:
5x > -50
x > -10
Answer:
X >/ -10 (imagine this is more or equal to symbol lol)
Step-by-step explanation:
1. subtract 13 from both sides
5x +13-13 >/ -37 -13
2. Simplify
5x >/ -50
3. solve for x (which means divide by 5)
5x/5 >/ -50/5
x>/ -10

Does the equation y = 2.3x represent a
linear or nonlinear function? Explain.
Answer:
y = 2.3x is a linear function.
Step-by-step explanation:
A linear function is a function with all of its terms to the first degree, in other words, none of its terms has an exponent. This means that when the function is plotted out, the resulting graph will be a line. The function, ( y = 2.3x) satisfies both of these requirements, hence it is linear.

Whats the answer to these? (These are called Proper fractions.)
Jeremiah ran for 3/10 of a mile and then walked another 2/5 of a mile. How far did he travel in all?
Daniel read 4/5 books and Edgar read 1/2 books. How many more books did Daniel read than Edgar?
Jared drove 2/8 miles to the restaurant. He drove another 1/4 miles to the mall. How many miles did he drive in all?
Answer to the first question: 7/10ths of a mile
Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: [tex]\frac{2*2}{5*2} = \frac{4}{10}[/tex]. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.
Answer to the second question: Daniel read three (3/10) more books
Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: [tex]\frac{4*2}{5*2} = \frac{8}{10}[/tex]. For Edgar, that would mean: [tex]\frac{1*5}{2*5} = \frac{5}{10}[/tex]. So, Daniel read 3 more books than Edgar.
Answer to the third question: 2/4 mile (or 1/2 a mile)
Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.
Answer and Step-by-step explanation:
1. Convert [tex]\frac{2}{5}[/tex] to have a denominator of 10.
[tex]\frac{2}{5}[/tex] × [tex]\frac{2}{2}[/tex] = [tex]\frac{4}{10}[/tex]
[tex]\frac{3}{10} + \frac{4}{10} = \frac{7}{10}[/tex]
Jeremiah ran [tex]\frac{7}{10}[/tex] of a mile in total.
2. Convert the denominators of all the fractions to have a 10.
[tex]\frac{1}{2}[/tex] × [tex]\frac{5}{5} =\frac{5}{10}[/tex]
[tex]\frac{4}{5}[/tex] × [tex]\frac{2}{2} = \frac{8}{10}[/tex]
Daniel read [tex]\frac{3}{10}[/tex] more books than Edgar, since 8 books is more than 5 books by 3 books.
3. Convert [tex]\frac{1}{4}[/tex] to have a denominator of 8.
[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{2} = \frac{2}{8}[/tex]
[tex]\frac{2}{8} +\frac{2}{8}= \frac{4}{8}, or\frac{1}{2}[/tex]
Jared drove [tex]\frac{4}{8}[/tex], or [tex]\frac{1}{2}[/tex] miles in total.

Answer:
120 ft²
Step-by-step explanation:
12(8) + 4(6) = 120
Answer:
96ft
Step-by-step explanation:
First we can find the rectangle which would be
6*12=72
then we can find the triangle, since their are two triangles we can combine them to make a rectnagle so we can just do
6*4=24
then we can add them together
72+24=96

ifā=r, then which of the following are true statements?
Check all that apply.
O A. n1/r = a
✓ B. = a
c. a1/nur
O D. a' = n.
Answer:
B. a = rⁿ
C. a¹/ⁿ = r
Step-by-step explanation:
ⁿ√a = r
The above expression can be simplified as follow:
1. ⁿ√a = r
Recall:
ⁿ√a = a¹/ⁿ
Therefore,
a¹/ⁿ = r
2. ⁿ√a = r
Take the n square of both side
(ⁿ√a)ⁿ = rⁿ
(a¹/ⁿ)ⁿ = rⁿ
a = rⁿ

Answer:
2.5 x 10^11
Step-by-step explanation:
Answer:
[tex]2.5[/tex] x [tex]10^1^1[/tex]
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
[tex]2.5[/tex] x [tex]10^1^1[/tex]
Hope this helps.
