. How can you determine if two ratios are equivalent. Be sure to include examples to support you response.
Answer:
By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio. For example, if the ratios are 3:5 and 9:15, multiply 3 by 15 and 5 by 15 to get 45:75.
find x,y,and z if AB||CD
Step-by-step explanation:
Hey there!
75° + 28° + angle KFG = 180°( being linear pair)
103° + angle KFG = 180°
angle KFG = 180° - 103°
Therefore, angle KFG= 77°
Now;
angle KFG + 28° +22° + X= 180°{ co-interior angle}
77°+28° + 22°+x= 180°
X = 180°-127°
Therefore, X = 53°
y == X+22°= 75° { being alternate angle}
angle KFG+x+z = 180° {sum of interior angle of triangle}
77°+53° + z = 180°
z = 180° - 130°
z= 50°
Therefore, X= 53°, y = 75° and z= 50°.

You need a 15% alcohol solution. On hand, you have a 180 mL of a 45% alcohol mixture. How much pure
water will you need to add to obtain the desired solution?
You will need
mL of pure water
to obtain
mL of the desired 15% solution.
Submit Question
Let x be the amount of pure water that you use.
The solution you have contains 0.45 • 180 mL = 81 mL of alcohol.
However much water you use, it won't add any alcohol to the solution, so only its total volume changes. Its new volume would be (180 + x) mL. You want the new solution to have a concentration of 15% so that
(81 mL) / ((180 + x) mL) = 0.15
Solve for x :
81 / (180 + x) = 0.15
81 / 0.15 = 180 + x
540 = 180 + x
x = 360
Then the new solution will have a total volume of 180 mL + 360 mL = 540 mL.
So you need to use 360 mL of pure water to get 540 mL of 15% solution.
Write 2 x 10^3 in standard notation.
Answer:
2000
Hope this helps :)
Step-by-step explanation:
Since the exponent of the scientific notation is positive, move the decimal point 3 places to the right.
The standard notation of the expression is 2 x 10³ is 2000.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
2 x 10³
Standard notation means writing an expression without any base and exponents.
Now,
10³ can be written as 1000.
So,
2 x 10³
= 2 x 1000
= 2000
Thus,
The standard notation is 2000.

37.25, 35.5, 33.75, __, __.
Answer:
37.25, 35.5, 33.75, 32, 30.25.
Step-by-step explanation:
Subtract the first term from the second term:
35.5 - 37.25 = -1.75
Subtract the second term from the third term:
35.5 - 33.75 = -1.75
The common difference is -1.75.
To find each subsequent term, add the common difference to the current term.
33.75 + (-1.75) = 32
32 + (-1.75) = 30.25
Answer:
37.25, 35.5, 33.75, 32, 30.25.

Find the value of x
Answer:
We know that the area of a triangle is:
1/2 * base * height
We are given:
base = x + 6
height = x
area = 108 m^2
Applying the formula:
Area = 1/2 * base * height
108 = 1/2 * x * (x + 6)
x² + 6x = 216
x² + 6x - 216 = 0
x² + 18x - 12x -216 = 0 (Splitting the middle term)
x(x + 18) - 12(x + 18) = 0
(x + 18) (x - 12) = 0
Hence, we have 2 possible values for x: -18 or 12
Since taking x as -18 will result in the length of sides of this triangle to be negative, -18 is NOT the value of x
Therefore, x = 12

In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls
Answer:
390 girls.
Step-by-step explanation:
[tex]\frac{3}{5}[/tex] of 650 is 390.
A ratio shows us the number of times a number contains another number. The number of girls in the school will be equal to 260.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that in the school, there are 3 girls for every 2 boys. Therefore, the ratio of girls to boys in the school can be written as,
Ratio = Girls / Boys = 3 / 2
Now, as per the ratio of the girls to boys, we can assume that the number of girls and boys in the school are 3x and 2x, respectively.
Further, given that the total number of students in the school is 650. Therefore, the total number of students can be written as,
Number of boys + Number of girls = 650
3x + 2x = 650
5x = 650
x = 130
Thus, the number of girls in the school can be written as,
Number of girls = 3x
= 3 (130)
= 260
Hence, the number of girls in the school will be equal to 260.

A large operator of timeshare complexes requires anyone interested in making a purchase to first visit the site of interest. Historical data indicates that 20% of all potential purchasers select a day visit, 50% choose a one-night visit, and 30% opt for a two-night visit. In addition, 10% of day visitors ultimately make a purchase, 40% of one-night visitors buy a unit, and 40% of those visiting for two nights decide to buy. Suppose a visitor is randomly selected and is found to have made a purchase. How likely is it that this person made a day visit
Answer:
0.143.
Step-by-step explanation:
The first step to take in answering this question is to take or determine the probability in each cases, multiply and sum them up. Therefore, let us delve right into the solution of this problem;
[a]. Historical data indicates that 20% of all potential purchasers select a day visit. Thus, the probability that potential purchasers selects a day visit = 0.20.
[b]. Historical data indicates that 50% choose a one-night visit. Thus, the probability that potential purchasers selects a one-night visit= 0.50.
[c]. Historical data indicates that 30% of all potential purchasers opt for a two-night visit. Thus, the probability that potential purchasers opt for a two-night visit = 0.30.
[d].Historical data indicates that 10% of day visitors ultimately make a purchase. Thus, the probability that a day visitors ultimately make a purchase = 0.1.
[e]. The probability for 40% of one-night visitors buy a unit =0.4
[f]. The probability for 40% of two nights decide to buy =0.4.
STEP ONE: Determine the probability that the visitor makes a purchase.
The probability that the visitor makes a purchase = [a] × [d] + [b] × [e] + [c] × [f]. = 0.2 × 0.1 + 0.5 × 0.4 + 0.3 × 0.4 = 0.02 + 0.02 + 0.12 = 0.14.
STEP TWO: Determine How likely is it that this person made a day visit.
0.2 × 0.1/ 0.14 = 0.1428571428571429
