Answer:
Yes, they are equivalent expressions, by the Associative Property
Step-by-step explanation:
Both of these expressions are equal to:
4a + 5a + 3c
(and then, 9a + 3c)
This is all adding so you can add them all up without any of the parentheses. In the question at first the parentheses are grouping together the 5a and 3c, but in the second expression they are wrapped around the 4a and 5a. But in both expressions the order of the three terms does not change. Only the grouping changes. The terms are grouped differently, but the order DOES NOT change. This is Associative property. If the order changes it is Commutative property.

Hello i need help with my assignment thank you in advance and i know you deserve the point
Answer:
1) a = 51, 2) b = 57, 3) c = 53, 4) e = 49 d = 131, 5) f = 33, 6) g = 79, 7) h = 42 j = 47, 8) m = 59 k = 17 i = 104, 9) n = 55
Step-by-step explanation:
1.
You see that angle HJK has a total degree angle of 115, half of the angle is already stated to be 64 degrees, so you would just have to find the remainder. 115 - 64 = 51
2.
The question follows the same format, when you see the square in the corner it generally means that it is a 90-degree angle. So following the same steps as last time angle b would be 90 - 33 = 57
3.
Whenever there is a flat line given the angle is equal to 180 degrees, think of it as putting two 90 degree angles back to back. So if they equal 180 angle c would equal 180 - 127 = 53
4
This question is just a little different when you see crossing perpendicular lines angles across from each other equal the same amount, so angle d would be 131. Finding angle e is not hard either, back to question 3 for when it was just a straight line the same logic can be applied here. e would equal 180 - 131 = 49

Given that Segment AD=29, AE=21 and CE=99, find the indicated measures for x, y, and perimeter of kite ABCD.
Answer:
DE = BE = x
x = 29² - 21²
= √400
= 20
x = 20
y = 20² + 99²
= √10201
= 101
y = 101
perimeter of kite ABCD : 29 + 29 + 101 + 101
= 260

Answer:
1520.5
Step-by-step explanation:
The area of a circle is pi times r^2. r stands for radius. r, which is 22 squared is 484, Multiply that with pi and you have your answer.
Answer:
The area of circle is 1520.5 in².
Step-by-step explanation:
DIAGRAM :
[tex]\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large{22\ in}}\end{picture}[/tex]
[tex]\begin{gathered}\end{gathered}[/tex]
SOLUTION :
Here's the required formula to find the area of circle :
[tex]\longrightarrow{\sf{A_{(Circle)} = \pi{r}^{2}}}[/tex]
A = Area π = 3.14 r = radiusSubstituting all the given values in the formula to find the area of circle :
[tex]{:\implies{\tt{A_{(Circle)} = \pi{r}^{2}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(22)}^{2}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(22 \times 22)}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(484)}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14 \times 484}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 1520.53}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} \approx 1520.5}}}[/tex]

School yearbooks cost $23. Fifty-six yearbooks have already been sold. How many more yearbooks x must be sold to earn at least $2001? Write your answer as an inequality.
Answer:
x [tex]\geq[/tex] 31
Step-by-step explanation:
Total number of the yearbooks is 56 + x
Total money earned is 23*(56 + x)
so 23*(56 + x) [tex]\geq[/tex] 2001
56 + x [tex]\geq[/tex] 2001/23 = 87

Use intercepts to graph the linear equation 5x+3y=30 .
Identify the points corresponding to the intercepts.
Answer: (6, 0) (0, 10)
Step-by-step explanation:
Intercepts occur when the axis is crossed, which is when the other axis is at 0. Plug in 0 for x & y. 5x + 0 =30 means x = 6. 3y + 0 =30 means y is 10.

1. Ms. Hogan and Ms. Brantley believe that less than 30% of students at Olympia High School completed their math homework last week. They enlist the help of all the math teachers and select a random sample of students and determine the percentage of those who completed their homework last week. 2. A company claims they have a diagnostic test that can detect cancer 90% of the time for those who have cancer. 150 people who have been diagnosed with cancer are given this diagnostic test. 108 of the individuals is identified as having cancer. Does this study provide convincing evidence that percentage of those diagnosed by this test is different than the company claims
Answer:
Yes
Step-by-step explanation:
Number 1 isnt asking a question.
2. If you divide 108/150= 0.72%
That is 18% percent off from what they claim which is quite a bit. Im not sure what is considered the "close enough" percentage but 18 is definitely more.

3^2y-1 = (9)(27)^y-2 calculate the value of y
Thank you
Answer:
y = 3
Step-by-step explanation:
3^2y - 1 = (9)(27)^y - 2
3^2y-1 = 243^y - 2
log(243)/log(3) = 5
2y - 1 = 5(y - 2)
2y - 1 = 5y - 10
-5y -5y
-3y - 1 = -10
+ 1 +1
-3y = -9
-3 -3
y = 3
Multiply: 1 1/6 x 6/11 =
Solution:
To solve a mixed fraction multiplication problem, you must:
Convert the fractions into improper fractions. (If the fractions are proper, you can skip this step.)Simplify the fractions If possible. (If it is not possible, you can skip this step.)Multiply the fractions (numerator with numerator and denominator with denominator).After reviewing how to multiply an improper fraction, let's solve the multiplication problem.
1 1/6 x 6/11=> (6 + 1)/6 x 6/11 [According to step 1]=> 7/6 x 6/11 => 7/1 x 1/11 [According to step 2]=> 7 x 1/11 x 1 [According to step 3]The solution to the multiplication problem is 7/11.
[tex] \bf \nrightarrow \: 1 \frac{1}{6} \times 6 \frac{6}{11} [/tex]
Convert the mixed fraction to improper fraction by Multiplying the denominator with the integer and adding the numerator to the product of denominator and integer
[tex] \sf \underbrace{1 \frac{1}{6} = \frac{7}{6} }[/tex]
Now, Multiply the fractions
[tex] \bf \: \frac{7}{6} \times \frac{6}{11} [/tex]
Multiply the numerators and denominators
[tex] \bf \nrightarrow \: \frac{7 \times \cancel 6}{ \cancel6 \times 11} [/tex]
[tex] \boxed{ \sf \: ans \multimap \: \frac{7}{11} }[/tex]
5. The science class is raising monarch caterpillars.
One of the caterpillars weighs 2.3 ounces.
About how many grams does the caterpillar
weigh? Round to the nearest tenth.
Answer:
65.2 g
Step-by-step explanation:
1 ounce is approximately 28.35 grams. So, 2.3 ounces is ...
(2.3 oz) × (28.35 g/oz) ≈ 65.2 g
The caterpillar weighs approximately 65.2 grams.
_____
Additional comment
The exact conversion is 1 oz = 28.349523125 g. For a 3-significant figure answer, we only need a conversion factor accurate to 4 significant figures.

There fore 10 people's high five will be 45 keep repeating and finding out the high fives I got 300 but I'm not sure if it's correct
The required number of high fives is 300.
Given that,
There are 25 students and one teacher in the class. After an exam, everyone high-fives everyone else to celebrate how well they did. How many high-fives were there is to be determined.
In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.
Here,
There are 25 students
n = 25
For each high five, there would be at least 2 students,
r = 2
The number of high five is given by combination,
= 25 C 2
= 25 * 24 / 2
= 600 / 2
= 300
Thus, the required number of high fives is 300.
