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.

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.

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 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

Answer:

N^26

Step-by-step explanation:

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]

Answer:

Y-intercept = -1

Step-by-step explanation:

You can find the y-intercept by looking at the value of y when x is 0.

Answer:

Horizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.

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.

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

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.
