How many boys are there in a group of 27 students if there are four-fifths as many girls as there are boys?

Answer:

10 cm

Step-by-step explanation:

because RT = 35 and RS = 75 so ST = 70

The length of SQ is 10 cm.

Option A is the correct answer.

We have,

Two similar triangles.

ΔTPQ and ΔTRS

So,

TR/TP = TS/TQ

TR = (TP +PR)

TS = (TQ + QS)

Substituting.

TR/TP = TS/TQ

(TP + PR)/TP = (TQ + QS)/TQ

(30 + 5) / 30 = (60 + QS) / 60

35/30 = (60 + QS) / 60

7/6 = (60 + QS) / 60

7 = (60 + QS) / 10

70 = 60 + QS

QS = 70 - 60

QS = 10

Thus,

The length of SQ is 10.

Step-by-step explanation:

2+8=10

-2-6=8

-4+7=2

6-9=-3

-5-5=-10

7-7=0

Part b.)

Yes. 8° with a rise of negative 7 would look like this 8+-7= 1.

I'm not familiar with the iniger game but here's my best take on the questions

1) no because a positive plus a positive is positive

2) yes, positive plus negative can be negative if the negative is bigger than the positive ex.(5-15=-10

3) yes, negative plus negative is negative

sorry if this took too long but tried my best to hurry

When the table says that there has been a RISE, that means that you should ADD. When the table says there has been a FALL, that means you should SUBTRACT.

The second row and the second column is saying a RISE, meaning that you should ADD 8 and 2. 8 + 2 = 10. So the answer for that one would be 10 degrees celcius (third column, second row.) The numbers in bold are your equation for the second row and fourth column.

Here are the rest: AT MEANS AFTERNOON TEMPERATURE :)

3rd row: AT = -8 [degrees celcius] EQUATION: -2 - 6 = -8

4th row: AT = 3 [degrees celcius] EQUATION: -4 + 7 = 3

5th row: AT = -3 [degrees celcius] EQUATION: 6 - 9 = -3

6th row: AT = -10 [degrees celcius] EQUATION: -5 - 5 = -10

7th row: AT = 0 [degrees celcius] EQUATION: 7 - 7 = 0

Woohoo! We're done with that part now.

(b) So, as I said before, a RISE means you must ADD. If you have a rise in -7 degrees celcius, how would you write that mathematically? You would write it like this: + ( - 7 ). You are ADDING NEGATIVE SEVEN. I know it sounds weird, but it is what it is. NOW. Adding negative 7 IS THE EQUIVALENT of saying subtract seven. Here's an example:

10 + ( - 7 ) = 3 (this is true)

10 - 7 = 3 (this is also true)

Therefore, for b you would say that you agree because +(-7) is the equivalent of say 'minus 7'.

Answer:

Slope is 1/4 (0.25) while y-intercept is 5

Step-by-step explanation:

Here, we are interested in getting the y intercept and slope of the line joining the given points.

We can get the slope by using any two points

Let’s say (4,6) and (12,8)

Mathematically; slope

= (y2-y1)/(x2-x1) = (8-6)/(12-4) = 2/8 = 1/4 = 0.25

To get the y-intercept, we proceed

kindly recall that the equation of a straight line is;

y = mx + c

where m is the slope and c is the y-intercept

Let’s take any of the points (28,12)

Thus:

12 = 0.25(28) + c

12 = 7 + c

c = 12-7

c = 5

Answer:

x=1

Step-by-step explanation:

f(x) is a fancy way of saying Y. So whenever you see that, you can just say its y= something.

y=-3x+4

1=-3x+4

Move the -3x to the other side where the one is. By doing this, the 3x will become positive.

3x+1=4

Now just subract one from 4

3x=3

And divide 3 from both sides.

x=1

No such thing as cot (61,4). I think you meant to say cot (61.4°). See the difference?

So, cot (61.4°) is approximately -0.139844.

Rounded to 3 decimal places we get -0.140.

Answer:

5 cups

Step-by-step explanation:

hi! to find the sum of the soup mix, we have to add all the fractions together.

7/4 + 1/2 + 5/3 + 1/3 +1/4 + 1/2

we have to find a common denominator for each, which is the LCM of the denominators. this would be 12. let's change the fractions so we can add them up.

21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12

add the numerators and keep the denominators the same.

(21+6+20+4+3+6)/12

60/12

this simplifies to 5.

the total amount of soup mix is 5 cups.

Answer:

5 cups of soup mix

Step-by-step explanation:

Make all the denominators equal. The lowest common denominator is 12 so multiple the denominators with 4 by 3, 2 by 6, and 3 by 4.

[tex]\frac{7}{4} *3=\frac{21}{12}[/tex]

[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]

[tex]\frac{5}{3} *4=\frac{20}{12}[/tex]

[tex]\frac{1}{3} *4=\frac{4}{12}[/tex]

[tex]\frac{1}{4} *3=\frac{3}{12}[/tex]

[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]

Now that all the fractions have the same denominator you can add them all together.

[tex]\frac{21}{12} +\frac{6}{12} +\frac{20}{12} +\frac{4}{12} +\frac{3}{12} +\frac{6}{12}=\frac{60}{12}[/tex]

Then simplify the fraction to find out how many total cups of soup mix you have.

[tex]\frac{60}{12} =5[/tex]

5 cups of soup mix

Step-by-step explanation:

This is an easy division problem. If you remove the decimal places, and use long division accordingly, the answer would be 7 slices.

Answer:

a = 60

60°, 60°, 120°, and 120°

Step-by-step explanation:

So we know that the sum of the angle measures of the quadrilateral is 360° and that the four angle measures are a, 2a, a, and 2a. This means that the sum of a, 2a, a, and 2a should equal 360.

a + 2a + a + 2a = 360

Combine like terms.

6a = 360

Divide both sides by 6.

a = 60

So the value of a would be 60.

Now to find the angle measures from least to greatest, we would have to find the values of a, 2a, a, and 2a.

a = 60

2a = 120

a = 60

2a = 120

So the angle measures from least to greatest is 60°, 60°, 120°, and 120°.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

a=60 degrees

Step-by-step explanation:

Total angle measurements=360 so

2a+2a+a+a=360

2(60)+2(60)=240

240+60+60=360

----------------------------

So a=60
