Find a similarity ratio is the ratio of perimeter's for to regular pentagons with areas of 16 cm Square and 49 cm Square
Answer:
4 : 7
Step-by-step explanation:
Given 2 similar figures the if the ratio of perimeters = a : b
The the ratio of areas = a² : b²
Here
ratio of areas = 16 : 49 , then
ratio of perimeters = [tex]\sqrt{16}[/tex] : [tex]\sqrt{49}[/tex] = 4 : 7

Answer:
508sq. cm
Step-by-step explanation:
surface area of a prism = 2(lw + wh + lh)
For the larger prism
Surface area = 2(2*10 + 2 * 12 * 10*12)
Surface area = 2(20+24+120)
Surface area = 2(164)
Surface area = 328sq.cm
For the smaller prism
Surface area = 2(3*6 + 3 * 8 * 6*8)
Surface area = 2(18+24+48)
Surface area = 2(90)
Surface area = 180 sq.cm
Surface area of the figure = 328 + 180
Surface area of the figure = 508sq. cm
A carpet company charges $4 per square foot plus a $100 installation charge. Write an expression for the total cost of x square feet of carpet.
Answer: 4x + 100
Step-by-step explanation:
The company charges $4 per foot plus an installation charge of $100.
There is therefore both a fixed element and a variable element.
The fixed element is the $100 installation charge
The variable element is 4 * the number of square feet of carpet which is x: 4 * x
Formula puts them together to give:
= Variable cost + Fixed cost
= 4 * x + 100
= 4x + 100

middle school has 600 students and 34% of them are in the 8th grade. One-fourth of 8th graders walk to school. How many 8th grade students walk to school? A. $4.50 B. $9.00 C. $12.00 D. $48.60
Answer: 51 students
Step-by-step explanation:
There are 600 students in this school and 34% are in 8th Grade.
The number of students in 8th grade is:
= 34% * 600
= 204 students
Then out of these 204, 1/4 walk to school. The number of students walking to school is therefore:
= 204 * 1/4
= 51 students

I divided 6394 by 42 but I don’t know the remainder. Does it have one or not?
Answer:
The answer is 152 r10
Step-by-step explanation:
There is indeed a remainder when dividing 6394 by 42.
6394 ÷ 42 = 152 with a remainder of 10, so, the remainder is 10.
Here, we have,
To determine if there is a remainder when dividing 6394 by 42,
we can perform the division and check if the result is a whole number or a decimal.
6394 ÷ 42 = 152 with a remainder of 10
Since the division does not result in a whole number,
but rather a quotient of 152 with a remainder of 10,
it indicates that there is indeed a remainder when dividing 6394 by 42.

The Blue Diamond Company advertises that their nut mix contains (by weight) 40% cashews, 15% Brazil nuts, 20% almonds and only 25% peanuts. The truth-in-advertising investigators took a random sample (of size 20 lbs) of the nut mix and found the distribution to be as follows: 5 lbs of Cashews, 6 lbs of Brazil nuts, 5 lbs of Almonds and 4 lbs of Peanuts. At the 0.05 level of significance, is the claim made by Blue Diamond true? Select the [p-value, Decision to Reject (RH0) or Failure to Reject (FRH0)].

What is Chi- square test?A chi-squared test (also chi-square or χ2 test) is a statistical hypothesis test that is valid to perform when the test statistic is chi-squared distributed under the null hypothesis, specifically Pearson's chi-squared test and variants thereof. Pearson's chi-squared test is used to determine whether there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table.
The data is given as follow:
The experimental weight of cashews = 40 % of 20lbs
= 8
The experimental weight of Brazil Nuts = 15 % of 20lbs
= 3
The experimental weight of Almonds = 20 % of 20lbs
= 4
The experimental weight of peanuts = 25 % of 20lbs
= 5
The observed value is :
Cashews = 5Brazil Nuts= 6Almonds= 5Peanuts= 4So, [tex]{\displaystyle \chi }[/tex] =[tex]\frac{(O-E)^{2}}{E}[/tex]
[tex]{\displaystyle \chi }[/tex]= [tex]\frac{(5-8)^{2}}{8} + \frac{(6-3)^{2}}{3} + \frac{(5-4)^{2}}{4} +\frac{(4-5)^{2}}{5}[/tex]

pvalue = p([tex]{\displaystyle \chi }^{2}[/tex] > 4.575) = [tex]{\displaystyle \chi }^{2}[/tex] cdf(4.575, 99999, 3)

There are 520 employess at greenville publishing. Jasmine surveys a representative sample of employees on their transportation costs each month. The reults are shown in the box plot.
Answer:
130 ; 50% ; 25%
Step-by-step explanation:
Using te boxplot to answer the underlying questions :
Number of employees who spend $10 or less corresponds to the lower quartile, which is up to 25% of the distribution :
Total number of employees = 520
Number of employees who spend $10 or less = 25% of 520 = 0.25 * 520 = 130 employees.
Percentage of employees who spend from $10 to $45 = Interquartile range
$10 corresponds to lower quartile = 25%
$45 corresponds to upper quartile = 75%
IQR = 75% - 25% = 50%
Percentage who spend $45 or more
$45 corresponds to the upper QUARTILE (Q3) :
45 or more = 100% - Q3 = 100% - 75% = 25%

1. A 5-liter cleaning solution contains 30% bleach. A 3-liter cleaning solution contains 50%
bleach. What percent of bleach is obtained by putting the two mixtures together?
5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.
3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.
Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is
(3 L) / (8 L) = 0.375 = 37.5%

Condense (cos92°)(cos133°)-(sin92°)(sin133°) into a singular trigonometric function expression, then find the exact value.
Answer:
-1/√2
Step-by-step explanation:
According to trigonometry identity
cos(A+B) = cosAcosB - sinA sinB
Given the expression
(cos92°)(cos133°)-(sin92°)(sin133°)
This can be expressed as cos(92+133) where A = 92, B = 133
(cos92°)(cos133°)-(sin92°)(sin133°)
= cos(92+133)
= cos225
= -0.7071
= -1/√2
Hence the exact value is -1/√2
