Answer: PART A : [tex]\frac{4.4}{x}[/tex] = [tex]\frac{3}{4}[/tex]
PART B : 5.9 FEET
Step-by-step explanation:
Length of the first sign = 4.4 feet
height of the first sign = 3 feet
Length of the second sign = x feet
height of the second sign = 4 feet
If two shapes are similar , then the ratio of their sides are equal,
That is ;
[tex]\frac{h_{1}}{h_{2} }[/tex] = [tex]\frac{L_{1}}{L_{2} }[/tex]
PART A
[tex]\frac{4.4}{x}[/tex] = [tex]\frac{3}{4}[/tex]
PART B
[tex]\frac{4.4}{x}[/tex] = [tex]\frac{3}{4}[/tex]
cross multiplying , we have
3x = 4.4 x 4
3x = 17.6
Divide through by 3
x = 17.6/3
x = 5.86666666666667
x≈ 5.9 feet
Therefore , the length of the new sign is 5.9 feet
Make a conjecture about the diagram below. Do you think you can conclude that △JKL ≅ △XYZ? Explain your reasoning.
Answer:
△JKL ≅ △XYZ by HL congruency for right triangles
Step-by-step explanation:
If only given two sides and an uncontained angle, the triangles may not necessarily be congruent. However, since the given angle is a right angle, they are congruent.
When given that the hypotenuse and any "leg" of the right triangles are equal, the triangles are congruent.
Since one angle is 90°, the other two angles must be acute. This is unlike the ambiguous case when given an uncontained acute angle, where two possible triangles can be made by making another angle obtuse.
Imagine an isosceles triangle cut in half at the altitude, creating two right triangles (JKL and XYZ). They have the same angle measures. Each with a right angle, the angle that had an equal measure in the isosceles, and the unequal angle bisected. For the triangles' sides, the isosceles base was bisected by the altitude, and they have the same altitude.
Rena evaluated 3/4 ÷ 2/5 and got an answer of 1 7/8. Which statement is true about her answer
Rena's answer is correct.
To evaluate whether Rena's answer is correct, we need to perform the division of the two fractions 3/4 and 2/5. To divide one fraction by another, you multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by flipping its numerator and denominator.
Here is a step-by-step solution:
Step 1: Write down the problem.
\[ \frac{3}{4} \div \frac{2}{5} \]
Step 2: Find the reciprocal of the second fraction.
The reciprocal of \( \frac{2}{5} \) is \( \frac{5}{2} \).
Step 3: Multiply the first fraction by the reciprocal of the second.
\[ \frac{3}{4} \times \frac{5}{2} \]
Step 4: Multiply the numerators together and the denominators together.
\[ \frac{3 \times 5}{4 \times 2} \]
\[ \frac{15}{8} \]
Step 5: Simplify the fraction if necessary.
In this case, \( \frac{15}{8} \) is an improper fraction because the numerator is larger than the denominator. We can convert it into a mixed number.
The whole number part of the mixed number is obtained by dividing the numerator by the denominator:
\[ 15 \div 8 = 1 \text{ with a remainder of } 7 \]
So, the mixed number is \( 1 \frac{7}{8} \).
Conclusion:
Rena's answer of \( 1 \frac{7}{8} \) is correct. The statement about her answer is true; she correctly evaluated the division of \( \frac{3}{4} \) by \( \frac{2}{5} \).
starting in 2000 what is estimated population and annual growth rate of 19,169,000 at 0.6% for 2025 not sure how to do this
Answer:
The estimated population in 2025 will be 22261221.
Step-by-step explanation:
Let us assume that the annual growth rate is compounded annually on the population.
Now, in 2000, the population was 19169000 and the annual growth rate is 0.6%, the the population in the year 2025 will be given by
[tex] 19169000(1 + \frac{0.6}{100} )^{25} = 22261220.7[/tex] ≈ 22261221

what is the function, domain and range of {(1,1) (2,2) (3,5) (4,10) (5,15)}?
Step-by-step explanation: To determine whether the relation shown here is a function, it's important to understand that a function is a relation in which each x-term corresponds to exactly one y-term.
Each of the x-terms shown here 1, 2, 3, 4, and 5 appears only once so each x-term corresponds to only one y-term. So yes, this relation is a function.
The domain of a relation is the set of all the x-terms of the relation. So here, the domain will be the set of all the x-terms or {1, 2, 3, 4, 5}.
The range of a relation is the set of all the y-terms of the relation. SO here, the range will be the set of all the y-terms or {1, 2, 5, 10, 15}.
If g(x) is the inverse of f(x) and S(x) = 4x+12, what is g(x)?
g(x) = 12x + 4
g(x) = 4x12
g(x) = x= 3
8(t) = 1x-3
Answer:
[tex]g(x)=\frac{1}{4}x-3[/tex]
Step-by-step explanation:
we have
[tex]f(x)=4x+12[/tex]
Find the inverse
step 1
Let
y=f(x)
[tex]y=4x+12[/tex]
step 2
Exchange the variables (x for y and y for x)
[tex]x=4y+12[/tex]
step 3
Isolate the variable y
we have
[tex]x=4y+12[/tex]
Subtract 12 both sides
[tex]x-12=4y[/tex]
Divide by 4 both sides
[tex]y=\frac{x-12}{4}[/tex]
simplify
[tex]y=\frac{1}{4}x-3[/tex]
step 4
Let
[tex]f^{-1}(x)=y[/tex]
[tex]f^{-1}(x)=\frac{1}{4}x-3[/tex]
we have that
[tex]g(x)=f^{-1}(x)[/tex]
therefore
[tex]g(x)=\frac{1}{4}x-3[/tex]

Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8 ?
A: 115
B:200
C:11,500
D:20,000
Answer:
2.3 × [tex]10^{-4}[/tex] is 20,000 times greater than 1.15 × [tex]10^{-8}[/tex]
Step-by-step explanation:
Given as :
The first number= x = 2.3 × [tex]10^{-4}[/tex]
The second number= y = 1.15 × [tex]10^{-8}[/tex]
Let The first number is z times greater than second number
i.e x = z × y
Or, z = [tex]\dfrac{x}{y}[/tex]
Or, z = [tex]\dfrac{2.3\times 10^{-4}}{1.15\times 10^{-8}}[/tex]
Or, z = 2 × [tex]10^{4}[/tex]
∴ z = 20,000
So,The first number is 20,000 times greater than second number
Hence, 2.3 × [tex]10^{-4}[/tex] is 20,000 times greater than 1.15 × [tex]10^{-8}[/tex] . Answer

A students cost for last semester at her community college was $2800. She spent $504 of that on books. What percent of last semesters college cost was spent on books
Answer: 18%
Step-by-step explanation:
The percentage spent on book = cost of books / total cost x 100
% spent on book = 504/2800 x 100
= 18
Therefore , the percentage spent on book is 18
what is the correct answer to the question
Answer:
4.37%
Step-by-step explanation:
Given: Value of object in 1997 is $5000
Value of object in 2012 is $4500.
Number of years (2012-1997)= 15 years
∵We know that there is growth in value of object over multiple years.
∴Compound annual growth rate (CAGR)= [tex][(\frac{end\ value}{initial\ value} )^{\frac{1}{n} } ] -1[/tex]
Remember, n = number of years
∴ Growth rate= [tex][(\frac{9500}{5000} )^{\frac{1}{15} } ]-1[/tex]
⇒Growth rate= [tex][(1.9)^{\frac{1}{15} } -1][/tex]
⇒Growth rate= [tex](1.9)^{0.0667} -1= 1.0437-1[/tex]
⇒ Growth rate= 0.0437
Now, finding percentage of growth rate
∴ [tex]0.0437\times 100= 4.37\%[/tex]
∴ Annual growth percent over the period of time is 4.37%

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
The number of students in 6th grade=100
The number of students in 7th grade=120
60% of the 6th grade band members
60%×110
60/100×110=0.6×110=66
85% of the 7th grade band members
85%×120=85/100×120
=0.85×120=102
We need to find how many more 7th graders went on the trip than 6th graders
For this we need to find difference of 7th and 6th grade

Step-by-step explanation:
a. A product raised to a power is equivalent to each of the multiplicand raised to that power as well. Example:
(xyz)ⁿ = xⁿyⁿzⁿ
(1·3·7)² = 1²(3²)(7²)
b. Is wrong. When you have addition/subtraction inside a parentheses, you have to foil. Example:
(a + b)² = (a + b)(a + b)
= a² + 2ab + b²
(1 + 3)² = (1 + 3)(1 + 3)
= 1² + 2(1)(3) + 3²
= 16
c. Numbers with the same root can be merged when you're multiplying/dividing them. Example:
√(a)√(b) = √(ab)
√(2)√(3) = √(2·3) = √(6)
d. You can only merge or split the root when multiplying/dividing.
You CANNOT merge the root when adding/subtracting.
√(a ± b) ≠ √(a) + √(b), this is NOT allowed

Step-by-step explanation:
Let x be the amount of time it takes each machine to make 1 cockpit, and y be the amount of time it takes each machine to make 1 propulsion system.
For machine A: 22 hours to produce 3 cockpits and 5 propulsion system.
For machine B: 44 hours to produce 6 cockpits and 10 propulsion system.
So, this will produce the following system of equations:
3x + 5y = 22 ⇒(1)
6x + 10y = 44 ⇒(2)
We can note that the second equation is two times the first equation.
So, the two equation are actually represent one equation.
OR, by another way the two equation have the same slope and y-intercept
So, the two equation are identical, therefore, we can't solve one equation with two variables.

Answer:
1) [tex]9\frac{1}{6}-8\frac{5}{6}=\frac{1}{3}[/tex]
2) [tex]10\frac{3}{4}-6\frac{4}{4}=3\frac{3}{4}[/tex]
Step-by-step explanation:
You can convert he mixed numbers to improper fractions:
1. Multiply the whole number part by the denominator of the fraction.
2. Add the product obtained to the numerator.
3. The denominator does not change.
Then:
[tex]9\frac{1}{6}=\frac{54+1}{6}=\frac{55}{6}\\\\8\frac{5}{6}=\frac{48+5}{6}=\frac{53}{6}\\\\10\frac{3}{4}=\frac{40+3}{4}=\frac{43}{4}\\\\6\frac{4}{4}=\frac{24+4}{4}=\frac{28}{4}[/tex]
Observe that, in each subtraction, the denominators are equal, then you can rewrite the denominator and subtract the numerators:
[tex]1)\ \frac{55}{6}-\frac{53}{6}=\frac{55-53}{6}= \frac{2}{6}=\frac{1}{3} \\\\2)\ \frac{43}{4}-\frac{28}{4}=\frac{43-28}{4}= \frac{15}{4}[/tex]
Divide 15 by 4. The quotient will be 3 and the remainder 3.
Then:
[tex]\frac{15}{4}=3\frac{3}{4}[/tex]
