Hey there! :)
Answer:
Anna's number = 13.
Olga's number = 52.
Step-by-step explanation:
We can express this situation as an equation to solve for both of their numbers.
Let x be Anna's number
Let 4x be Olga's number
Their numbers sum up to 65, therefore:
4x + x = 65.
Begin by combining like terms:
5x = 65
Divide both sides by 5:
5x/5 = 65/5
x = 13 = Anna's number.
Find Olga's number by plugging 13 into 4x:
4(13) = 52. This is Olga's number.
A triangle has sides 45, 4x and 2x−4. What is the possible range of x?
x>2
The greatest possible value cannot be stated as it is not mentioned whether it is a right angled triangle, which is hypotenuse, or which is the smallest/largest side.
Answer:
49/6 < x < 41/2.
Step-by-step explanation:
In any triangle, each side is shorter than the sum of two other sides.
It gives three independent inequality
45 < 4x + (2x-4), (1)
4x < 45 + (2x-4), (2)
2x-4 < 45 + 4x. (3)
From (1), 6x > 45 + 4 = 49 ---> x > 49/6
From (2), 2x < 45 - 4 = 41 ---> x < 4/2
From (3), 2x > -4 - 45 = -49 ---> x > -49/2
Juan did a survey in four butterfly parks and wrote the following observations: Butterfly Park Survey Park Number of Pink Butterflies Total Number of Butterflies P 25 53 Q 35 64 R 37 75 S 23 55 Based on the survey, which park had the greatest percentage of pink butterflies? Park P Park Q Park R Park S
Answer:
Park Q has greatest percentage of pink butterflies.
Step-by-step explanation:
Butterfly Park Survey Park P Q R S
No, of Pink Butterflies 25 35 37 23
Total Number of Butterflies 53 64 75 55
Now we are supposed to find which park had the greatest percentage of pink butterflies
So, Percentage of pink butterflies in park P =[tex]\frac{25}{53} \times 100=47.169\%[/tex]
Percentage of pink butterflies in park Q =[tex]\frac{35}{64} \times 100=54.68\%[/tex]
Percentage of pink butterflies in park R= [tex]\frac{37}{75} \times 100=49.33\%[/tex]
Percentage of pink butterflies in park S= [tex]\frac{23}{55} \times 100=41.81\%[/tex]
So, Park Q has greatest percentage of pink butterflies.
So, Option B is true
Hence Park Q has greatest percentage of pink butterflies.

59. A car dealership has SUVs and sedans in a ratio of
5:9. How many sedans does the car dealership
have if there are 140 SUVs?
Answer:
The car dealership has 252 sedans.
Step-by-step explanation:
Number of SUVs = 140
Ratio of SUVs to sedans = 5:9
Sum of ratios = 5+9 = 14
Total number of cars = 14/5 × 140 = 392
Number of sedans = 9/14 × 392 = 252
Joshua is going to mow lawns during his summer break. The graph in the figure shows a linear relationship between the number of weeks he will be
mowing and the number of lawns he will mow. If he earns $25 for each lawn he mows, how much money will he earn after mowing lawns 5 weeks?
A. $125
B. $750
C. $1,500
D. $3,000
Answer:
$1,500
Step-by-step explanation:
We see on the graph that he mows 60 lawns in 5 weeks so if we multiply 60 by 25 because 25 is the amount of money he makes for each lawn he mows, we get 1,500 dollars.

A coin is tossed and a number cube is rolled. What is the probability that the coin shows heads and the number cube shows 5? a. 1/6 b. 1/12 c. 2/3 d. 1/4
Answer:
1/12
Step-by-step explanation:
P( coin = heads) = number of heads / total = 1/2
P( cube = 5) = number of 5's / total =1/6
P( heads, 5) =1/2 * 1/6 = 1/12
The coin toss and the number cube roll are independent events.
This is because the result of the coin toss does
not affect the result of the number cube roll.
To find the probability of two independent events, we first find the probability of each event, then we multiply the probabilities.
Since there is only one way to get heads when tossing a coin and there are 2 possible outcomes, tossing a heads or tails, the probability of getting heads is 1/2.
Since there is only one way to roll 5 on a number cube, there
is 1 favorable outcome but six possible outcomes.
So the probability of rolling a 5 is 1/6.
Now multiply.
So we have 1/2 · 1/6 which is 1/12.

PLEASE HELP For a particular transformer, the voltage E in the circuits is related to the number of windings W of wire around the core by the equation E=40W. How many windings will produce a voltage of 760 V? A voltage of 760 V will be produced by ? windings.
Answer:
A voltage of 760V will be produced by 19 windings.
Step-by-step explanation:
Given the equation:
E = 40W
Where E is the Voltage in the circuits
and W is the number of windings
Given that E = 760V
To find: W = ?
Solution: Here, we have the given equation in 2 variables where value of 1 variable is given so other can be easily calculated by putting the value of given variable in the equation.
So, Putting the value of E in the given formula and finding W, the number of windings:
[tex]760=40 \times W\\\Rightarrow W = \dfrac{760}{40}\\\Rightarrow W = \dfrac{76}{4}\\\Rightarrow W = 19[/tex]
So, number of windings for a voltage E = 760V is 19.
A voltage of 760V will be produced by 19 windings.

Helps pls Three generous friends, each with some cash, redistribute their money as follows: Ami gives enough money to Jan and Toy to double the amount that each has. Jan then gives enough to Ami and Toy to double their amounts. Finally, Toy gives Ami and Jan enough to double their amounts. If Toy has $36 when they begin and $36 when they end, what is the total amount that all three friends have?
Answer:
The total amount that all three friends have = $258
Step-by-step explanation:
Three friends: let their initial money be Ami's money =A, Jan = B, Toy = C
Toy started with $36 and ended with same amount
C = $36
After Ami gives, She is left with= A-x
Jan becomes= 2B
Toy becomes= 2C = 2×36 = 72
After Jan gives, Jan is left with = 2B-y
Ami now has = 2(A-x)
Toy now has = 2(72) = 144
After Toy gives, Toy is left with= 144-z
Ami now has = 2(2)(A-x) = 4(A-x)
Jan now has = 2(2B-y)
Since Toy is left with $36 at the end:
36 = 144-z
z = 144-36 = 108
So Toy spent $108 to double his two other friend's money
Both Amy and Jan had $108 in total when Toy had $144
Difference between the deductions across = $108
The total amount that all three friends have = 144+108
The total amount that all three friends have= $258

In △ABC, AD is the angle bisector of ∠A and BE is the angle bisector of ∠B. If AD intersects BE at point O, find m∠AOB given the following: b m∠A = 125°, m∠B = 33° quick I will give brainliest, need in 5 minutes!
Answer:
∠AOB = 101°
Step-by-step explanation:
Given:
AD is the angle bisector of ∠A
BE is the angle bisector of ∠B.
∠A = 125°
∠B = 33°
Find:
∠AOB
Computation:
∠BAO = 125° / 2 = 62.5°
∠ABO = 33°/2 = 16.5°
So,
∠AOB + ∠BAO + ∠ABO = 180°
∠AOB + 62.5° + 16.5° = 180°
∠AOB = 101°
Tom and Jerry are selling fruit for a charity fundraiser. Customers can buy small boxes of oranges and large boxes of oranges. Tom sold 3 small boxes of oranges and 14 large boxes of oranges for a total of $203. Jerry sold 11 small boxes of oranges and 11 large boxes of oranges for a total of $220. Find the cost each of one small box of oranges and one large box of oranges. Please use equations to solve the problem.
Step-by-step explanation:
3x + 14y = 203
2. 11x + 11y = 220
3. Divide the last equation above by 11: x + y = 20
4. This is the same as saying x = 20 - y
5. Now, substitute for x in the first equation: 3(20 - y) + 14y = 203
6. The above equation simplifies to 60 - 3y + 14y = 203
7. Now express the equation in terms of y: 11y = 143
8. From the last equation, y = 13
9. Since x + y = 20, x = 7
10. Check: (3 times 7) + (14 times 13) = 21 + 182 = 203;
(11 times 7) + (11 times 13) = 77 + 143 = 220

Answer:
Option b.
Step-by-step explanation:
If the starting value a, the growth factor b, and the growth rate r, then

Answer:

-48 > -8x > -64 (subtract 1 from -47 and -63)
6 < x < 8 (divide inequality by -8; when you multiply/divide by a negative number you need to flip the sign)
Answer:
its wrong because when u moved the 8 to other side it would be positive. And u didnt switch sign for the 6
Step-by-step explanation:
-47 > 1-8x > -63
Seperate them into two inequalities
-47> 1-8x
Move 1 to the other side it will become -1
-47-1>-8x
-48>-8x
Divide -8 on both sides which will make the sign opposite because dividing with a negative number
6<x
1-8x>-63
Subtract 1 on both sides
-8x>-64
Divide -8 on both sides which will switch sign
x<8
