Step-by-step explanation:

collinear points lie on the same line

R is on the line joining AB

Answer:4.5

Step-by-step explanation:

Answer:

Absolute value means any value but always positive. So |-4.5|=4.5

Willy can cover in 1L paint

[tex]\\ \rm\rightarrowtail \dfrac{13.5}{3}=4.5m^2[/tex]

Can cover in 10L

[tex]\\ \rm\rightarrowtail 4.5(10)=45m^2[/tex]

Second one should be filled with 45

Answer:

4.5 : 1

45 : 10

Step-by-step explanation:

Given ratio:  13.5 : 3

To calculate equivalent ratios, we need to do the same operation to both sides of the ratio.

To reduce 3 L of paint to 1 L of paint, we need to divide by 3.

Therefore, we should also divide 13.5 by 3:

13.5 ÷ 3 : 3 ÷ 3

= 4.5 : 1

To increase 1 L of paint to 10 L of paint, we need to multiply by 10:

4.5 × 10 : 1 × 10

= 45 : 10

Answer:

16 gallons

Step-by-step explanation:

Since 4 quarts is equal to a gallon, you should divide 64 quarts by 4 to get 16 gallons

Answer:

Containing in one gallon, there is 4 quarts.

I like to order my units preferably so I can understand better;

QUARTS           4     (x16)   64

________ = ______ = ______ so x = 16

GALLONS          1     (x16)     x

Answer:

4.8

Step-by-step explanation:

Firstly, you take the ratio 12d/30t(d=dollars, t=tokens). And you switch it to (unknown)d/30t. And if you execute the formula(12 * 12 / 30) you get 4.8.

Answer:

[tex]1. \frac{4}{3}[/tex]

[tex]2.\frac{1}{3}[/tex]

Step-by-step explanation:

To find the scale factors, you find the length of one side from the image, and divide it by the length of the similar side in the image.

So, for #1, the image side is 8 units, and the pre-image is 6.

8/6 = 4/3

For #2, the image is  3 units, and the pre-image is 9 units.

3/9 = 1/3

A'=(10,2)

B'=(8,-4)

C'=(4,-2)

To rotate a point 90° clockwise about the origin,

The new coordinates become (y,-x)

So the first one was A(-2,10)

x=-2 & y=10

The new coordinates become A'(y,-x)

So y=10 and -x=-(-2)=2

A'(10,2)

Answer:

A' =(2,4)

B'=(8,2)

C′=(6,-2)

Answer:

X=4

Step-by-step explanation:

2(4)-1=7

8-1=7

7=7

Answer:

25

Step-by-step explanation:

Since y= 60 when x=240 it would be 0.25 and 0.25 x100 would be 25

Answer:

2k + 8 = 0

2k + 8 - 8 = 0 - 8

2k = - 8

2k/2 = - 8/2

k = - 4

Step-by-step explanation:

you gotta put the 8 on the other side by subtracting and the divide both sides to get k

Answer:

k = -4

Step-by-step explanation:

2k + 8 = 0

Subtract 8 from both sides.

2k = -8

Divide both sides by 2.

k = -4

Answer:

Let f be the number of friends

Let c be the cost of the party

As (f) is the independent variable, the number of friends will be along the x-axis.

As (c) is the dependent variable, the cost of the party will be along the y-axis.

If the cost of the party is $20 per person, then the equation to represent the relationship is:

c = 20 f

The measurements that will be dragged into the box is 1.4 feet, 1.31 feet, 1.44 feet.

The rest of the measurement wouldn't be within the bounds and thus will not be dragged in.

Answer:

the measure of angle is m(<a)=40

Step-by-step explanation:

the intirior angles of all triangles add up to 180

with this you can subtract the 90 degree angle and the 50 degree angle from the total of 180 degrees.

180

90

-50

---------

=40 degreese

hoped this helped.

Step-by-step explanation:

a+50+90=180°(being sum of angle of right angled▲)

or, a+140= 180°

or, a=180°_ 140°

Therefore, a=40°

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is  C

Step-by-step explanation:

From the question we are told that

  The population mean is p =  64

  The sample size is  n =  56

   The sample mean is  [tex]\=  x  =  64.79[/tex]

  The standard deviation is  [tex]s = 2.77[/tex]

    The null hypothesis is  [tex]H_o :  \mu =  64[/tex]

    The alternative hypothesis is  [tex]H_a :  \mu > 64[/tex]

    The test statistics [tex]t =  2.13[/tex]

    The level of significance is  [tex]\alpha  = 0.05[/tex]

    The p-value  is  [tex]0.01 <  p-value <  0.025[/tex]

Given that the  [tex]p-value  <  \alpha[/tex] we reject the null hypothesis

Answer:

C. 72

Step-by-step explanation:

The whole angle measures 106 degrees as mentioned on top and we know that angle HFG is 34 degrees because it says so in that angle. Just do this: 106-34. The answer is 72. We subtract because we're finding the remaining/missing number in this problem. If you want to check if your answer is correct, you can add 72 and 34.

Another way you could do this is by just adding each option with 34 to see if you get a total of 106.

Step-by-step explanation:

his salary =$2000

his commission should be (to make a total of $4000/month )=$4000-$2000 =$2000

let he should sell x amount over $7000 to get $2000 commission

So,   7% of x = 2000

             7x/100 = 2000

               x= (2000*100)/7 =28571.43 approx

As he will get commission on sales over $ 7000,so his should sell in a month

                             =$7000+$28571.43

                             = $ 35571.43

Answer:

y = 5

x = 0

Step-by-step explanation:

soo i think elimination was this:

    so first lets make -x = 3x

so we multiply -3 to the whole equation

3x + 3y = 15

now we eliminate (i think this is elimination)

    3x + 5y = 25

   -

    3x + 3y = 15

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

     0 + 2y = 10

2y = 10

y = 5

now substitute to one of the original equations

3x + 5(5) = 25

3x + 25 = 25

3x = 0

x = 0

now lets check

-0 -5 = -5?

-5 = -5
