Maggie's favorite salad dressing is made with 0.04 liter of vinegar and 0.4 liter of olive oil.She compares the value of the 4 in each amount.Which statement is true? 1:the value of the 4 in 0.04 is 100 times the value of the 4 in 0.4. 2:the value of the 4 in 0.04 is 10 times the value in of the 4 in 0.4. 3:the value of the 4 in 0.04 is the value of the 4 in 0.4 divided by 10. 4:the value of the 4 in 0.04 is the value of the 4 in 0.4 divided by 100
Answer:
3:the value of the 4 in 0.04 is the value of the 4 in 0.4 divided by 10.
Step-by-step explanation:
This is because in decimal places, we have what is called place value. In a decimal number after the decimal point, each number place is divided by an increasing power of 10. So, for example, if we have a decimal number 0.82, the place value of the 8 is 8/10 while that of the 2 is 2/10² = 2/100.
So, in the given numbers, 0.04 has a place value of 4/100 and 0.4 has a place value of 4/10. So, we can see that 4/100 = 4/10 ÷ 10 = 4/10 × 1/10.
So, the value of the 4 in 0.04 is the value of the 4 in 0.4 divided by 10.

If the ratio of red roses to pink roses is 5 to 4 and there are a total of 45 roses, how many of them are red?
Answer: There will be 25 red roses and 20 pink roses.
Step-by-step explanation: If the ratio is 5 to 4 then we can add 5 and 4 together to get 9. 45 is divisible by 9. 9 goes into 45, 5 times. If we multiply 5 by 5 then it will be 25 which is 5/9 of 45. Then if we do the same thing but we multiply 4 times 5 then we will get 20 which is the other 4/9 of the ratio.

Q=
Answer:
R is 51 degrees
P is 51 degrees
Q is 78 degrees
Step-by-step explanation:
This is an isosceles triangle so R and P are the same angle degree.
First set them equal to each other to be (4x+23)=(2x+37) to get x=7.
Substitute X with 7: 4(7)+23=2(7)+37. It will be 51=51.
A triangle is equal to 180 degrees so 51+51 is 102 and 180-102 is 78.
Hope this helped :)

If L is parallel to M, find the values of x, y, and all 3 angles.
Answer:
8x - 14 = 5x + 34 (alternate exterior angles)
8x - 5x = 34 + 14
3x = 48
x = 48/3
x = 16
5y + 16 + 8x - 14 = 180 (linear pair)
5y + 16 + 8(16) - 14 = 180
5y + 16 + 128 - 14 = 180
5y + 130 = 180
5y = 180 - 130
5y = 50
y = 50/5
y = 10
∠ (8x - 14) = 114 [(8 × 16 -14)=114]
∠ (5x + 34) = 114 [(5 × 16 +34)=114]
∠ (5y + 16) = 66 [(5 × 10 +16)=66]

Alisa and Chelsea paid a total of $31 to rent a canoe. Write
and solve an equation to find h, the number of hours they
rented the canoe.
Answer:
6+ 10h =31
Step-by-step explanation:
That's your equation. You have to then subtract six from the six and 31. Which would get you 10h=25. Divide 10 from both sides and get h=2.5. They rented a canoe for 2 and a half hours.

on tuesday norachai bought seven boxes. on wednesday half of the boxes that he had were destroyed. on tuesday there were only 13 left. how many did he have on monday?
Answer:
19
Step-by-step explanation:
First you figure out x/2=13
Then you find out x=26
So then you figure out x+7=26
Which is then x=19
The number of boxes Norachai had on Monday is 19 boxes.
Given that, on Tuesday Norachai bought seven boxes.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of boxes had on Monday be x.
Now, the number of boxes had on Tuesday
= x+7
Now, on Wednesday half of all the boxes that he had were destroyed
= (x+7)/2
As, given on Thursday he had left boxes = 13
So, (x+7)/2 = 13
⇒ x+7=26
⇒ x=19 boxes
Therefore, the number of boxes Norachai had on Monday is 19 boxes.

Another submarines dissent can be modeled as Y= -250 X, where why is the vertical position and access time in hours. How long will it take the submarine to make that I sent
Answer:
Step-by-step explanation:
The question is not well structuredand lack some information.
Restructured:
Another submarines dissent can be modeled as Y= -250 X, where Y is the vertical position and X is the. access time in hours. How long will it take the submarine to make dissent of -200ft?.
To get the time taken to dissent -200ft., we will have to substitute
Y = -200ft into the given expression as shown;
Y = -250X
-200 =-250X
Rearrange
-250X = -200
-25X = -20
Divide both sides by -25
-25X/-25 = -20/-25
X = 20/25
X = 4/5 hrs
Convert to minutes
X = 4/5 × 60
X = 4×12
X = 48minutes
Hence submarine will take 48minutes to dissent -200ft
The weather outside was very abnormal. The temperature started out at 6°C in the morning and went to -13°C at noon. It stayed at that temperature for six hours and then rose 10°C. How far below the freezing point (0°C) was the temperature at 6 p.M.? *
Answer:
At 6 pm, the temperature was 13°C below the freezing point
Step-by-step explanation:
Let us first express the information clearly to determine the temperature at 6 p.m:
The temperature in the morning = 6°C
the temperature at noon (12pm) = -13°C
It stayed at that temperature for six hours; this means that the temperature from 12 noon to 6 pm = -13°C
∴ Temperature at 6 pm = -13°C
Next let us calculate how far -13 is, below freezing point (0)
Difference = 0 - (-13)
= 0 + 13 = 13°C
Therefore, at 6 pm, the temperature was 13°C below the freezing point
