Leah drives her truck 270KM in the same time Deborah drives her car 250KM. If Leah drives 4km/h faster than Deborah. What is each of their driving speeds?

Answer:

20 square units

Step-by-step explanation:

you can separate this irregular polygon into 2 rectangles:

Rectangle 1 (bigger): 3 Units X 4 Units = 12 square units

Rectangle 2 (smaller): 2 Units X 4 Units = 8 square units

Add the 2 areas: 12+8 square units = 20 square units

Answer:

20

Step-by-step explanation:

To get the area of this irregular polygon, we have to turn the irrelgular polygon into 2 shapes. (Imagine a line drawn from the corner/wall that separates the unit 1 and 4 units down the bottom of the shape. I don't rlly know how to explain it sorry).

First we calculate the first rectangle which is simple, you just have to multiply! 3x4= 12.

Then for the second one, we have to subtract. Basically, 8 units minus 4 units is equal to 4 units meaning that our lenght is four units. Then 3 units minus 1 unit is equal to 2 units which is our width. (i'm deeply sorry if I couldn't explain it the best) Now we just do 4x2=8.

Now we just add 12 and 8 which gives us 20!

Answer:

37.5

Step-by-step explanation:

cosФ = \(\frac{A}{H}\)

cos(33°35') = \(\frac{m}{45}\)

m = 45 × cos(33°35')

m = 37.5 (1d.p.)

Answer:

Step-by-step explanation:

reason 1:

opening of brackets to solve the expression

reason 2:

in multiplication order is followed i.e. the number always lead the variable in the expression

reason 3:

for clarification brackets are added to multiply like terms i.e. numbers with numbers and variable with the variable

reason 4:

the solved and simplified expression is delivered as a result

Answer:

Subtract 58 from both sides

Step-by-step explanation:

Answer: y = -1/4x - 6

Step-by-step explanation: the slope is -1/4 because slope = rise/run, the rise is 1, and the run is 4 and the slope is negative. the y intercept is -6 because it passes through -6 at the y axis.

Answer:

-1/4x + -6

Step-by-step explanation:

The slope is -1/4 because slope = \(\frac{rise}{run}\),

So:

-\(\frac{1}{4}\) is the slope, also is negative.

The y intercept is -6 because it passes through -6 at the y axis.

( I also checked it on khan Academy and it was correct)

Answer:

\(y^1=-1(x-1)+(1+9)\)

Step-by-step explanation:

\(y=-1x+1\ \ == > \ \ y^1=-1(x-1)+(1+9)\)

-1 horizontally = 1 units left (the x-axis)

9 vertically = 9 units up (y-axis)

Hope this helps!

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Answer:A)

Yes, the relationship is proportional.

B)

66,000 miles.

Step-by-step explanation:

A)

Yes, the graph represents a proportional relationship.

Since, A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:  

y=kx

for some constant k , called the constant of proportionality .

As y=12000x hence the relationship is proportional.

B)

We calculate the equation of the graph with the help of two points on the graph namely (2,24000) and (4,48000) with the help of slope-intercept form of the line.

y=mx+c where m denotes the slope of the line and c denotes the y-intercept of the line.

Here when x=2 y=24000 and when x=4 y=48000

Hence, 24000=2x+c

and 48000=4x+c

on subtracting the above two equations we have:

m=12000 and c=0

Hence, the equation of line is y=12000x

Now the value at x=5.5 is:

y=12000×5.5=66,000

Hence, the number of miles the probe travels in 5.5. hours is 66,000 miles.

Step-by-step explanation:

Answer: 0.425 is a decimal number of 17/40 7.25 to the nearest thousands is 0 7.25 to the nearest hundreds is 0 7.25 to the nearest tens is 10 Check and cancel the factors of 84 and 100 if any factors in the numerator and denominator can be cancelled each other:

=(21 x 4)

(25 x 4)

84/100

=21/25

0.84 as a fraction is equal to 21/25

First things first, if you don't know what a numerator and a denominator are in a fraction, we need to recap that: Here's the little secret you can use to instantly transform any fraction to a decimal: Simply divide the numerator by the denominator: That's literally all there is to it! 5/12 as a decimal is 0.41666666666667, but just write 0.4. Next 5.75=

5 75/100

divide top and bottom by 25

5 3/4

0.007 as a Fraction Result: 0.007 as a Fraction equals 7 / 1000. Scroll down for detailed steps on how to convert 0.007 into a fraction.

in simplified form is 18.81. This when rounded to whole number becomes 19.

Similarly, in simplified form is 8.375 and when rounded to nearest whole number, it becomes 8.

Now, the difference will be 19-8=11

Answer: PLEASE GIVE ME BRAINLIEST I WORKED SO HARD ON IT

1.  \(\frac{17}{40}\)  = 0.425

2.  \(10\frac{7}{25}\)  =  \(\frac{257}{25}\)  =  10.28  =  10 (rounded)

3.  0.84  →  \(\frac{0.84*100}{1*100} = \frac{84}{100}\)  =  \(\frac{21}{25}\)  (lowest terms/simplest form)                                    

4. \(11\frac{5}{12} = \frac{137}{12}\) = 11.41

5.  5.75  →  \(\frac{5.75*100}{1*100} = \frac{575}{100}\)  =  \(\frac{23}{4}\)  (lowest terms/simplest form)

7.  0.007  →  \(\frac{0.007*1000}{1*1000} = \frac{7}{1000}\)  (lowest terms/simplest form)

8.  \(9\frac{5}{12}\) - \(3\frac{4}{5}\)  →  \(\frac{113}{12} - \frac{19}{5}\)  →  9.41 - 3.8   →  9-4 = 5 (the difference)

9.  The elapsed time between 1:28 p.m. and 4:05 p.m is 2 hrs & 37 min.

10.  The elapsed time between 7:13 p.m. and 3:45 a.m is 8 hrs & 32 min.

Answer: C. 6-4n

Step-by-step explanation:

    We will simplify the expression and see which one is equivalent.

Given:

  6n + 2(3 - 5n)

Distribute:

  6n + 6 - 10n

Subtract:

  -4n + 6

      This is the same as 6 - 4n, so our answer is C. 6-4n

Answer:

6-4n (C.)

Step-by-step explanation:

First you would do 2x3=6

2x-5n=-10n

6n+ -10n= -4n

6-4n
