Answer:

Slope is 1/2

Step-by-step explanation:

Use the slope formula. Say S = the 1st point and T = the 2nd point.

m = 20 - 10                    10                 1

     ------------      =      -----------    =      ---

      20 - 0                     20                2

The equation for slope is also y = mx + b

m is the slope, b is the y-intercept.

Therefore, if you look at the 1st choice, you can see that 1/2 is in the place of m, meaning that 1/2 is the slope of line ST

I dunno how to do the other way

Answer:

1 1/5 miles per hour

Step-by-step explanation:

multiply 3/5 and 1/2 and then you would get your answer

Speed = distance/ time

speed = 3/5 ÷ 1/2

speed = 3/5*2

speed = 6/5mph or 1.2 mph

8

The number of days

2

The number of advertisement ordered on Friday

x + 8

The total number of advertisement on both days

2x + 8

Answer:

A

Step-by-step explanation:

I took the test

Answer:

20.) Some charateristics to look for are "what's its leaf shape?" , "does this plant have spores?" , "does it have no leaves?" and "is it a vascular or non-vascular plant?". By naming its charateristics we can infer that it must be a fungus. This means its root system attaches to other plant roots in order to get nutrients for itself.

18.) If we observe the charateristics of the moss we might get an answer. Moss needs water in order to survive since it is the source of nutrients for the moss. The reason why the moss turned green after the rainstorm was because it got the nutrients it needed so it caused the moss to flourish again.

17.) We can use models to compare and contrast plant and fungus cells. By using evidence we can include that both the plant and fungus cells have some common characteristics, however plants are autotrophic, making their own energy, and have cell walls made of cellulose, but fungi are heterotrophic taking in food for energy and have cell walls made of chitin.

Step-by-step explanation:

y-1 =-3x-12

Equation of a line is y=mx+c

y=-3x-12 +1

y= -3x -11

parallel lines men you can use the same gradient so e,g y=-3x+12

Answer:

The equivalent expressions are;

9x + 9

and

9(x + 1)

Step-by-step explanation:

Mathematically, we should understand that an equilateral triangle has all of its sides equal

So if one side is 3x+ 3, the other sides too measures same

Therefore, the length of the rope represents the perimeter of the triangle

This is obtainable by adding all the side lengths together

This will be;

3x + 3 + 3x + 3 + 3x + 3 = 9x + 9

This is also same as 9(x + 1)

P.S Can I have brainliest?

Note: Consider all the numeric values are in the fraction form. Like [tex]14\to \dfrac{1}{4}[/tex], [tex]23\to \dfrac{2}{3}[/tex] etc.

Given:

A recipe calls for [tex]\dfrac{1}{4}[/tex] cup of brown sugar for every [tex]\dfrac{2}{3}[/tex] cup of white sugar.

To find:

The number of cups of brown sugar that are required for every cup of white sugar.

Solution:

We know that,

Required brown sugar for [tex]\dfrac{2}{3}[/tex] cup of white sugar =  [tex]\dfrac{1}{4}[/tex] cup

Using this, we get

Required brown sugar for 1 cup of white sugar =  [tex]\dfrac{\dfrac{1}{4}}{\dfrac{2}{3}}[/tex] cup

                                                                              [tex]=\dfrac{1}{4}\times \dfrac{3}{2}[/tex] cup

                                                                              [tex]=\dfrac{3}{8}[/tex] cup

So, [tex]\dfrac{3}{8}[/tex] cup of brown sugar is required for every cup of white sugar.

Therefore, the correct option is B.

Answer:

[tex]10+5\sqrt{3}[/tex]

Step-by-step explanation:

Given the expression: 5 / (2 - √3)

To rationalize the denominator, we multiply the numerator and denominator by the conjugate of the denominator. The conjugate of (2 - √3) is (2 + √3). Hence multiplying gives:

[tex]\frac{5}{2-\sqrt{3} }*\frac{2+\sqrt{3}}{2+\sqrt{3}} \\\\=\frac{10+5\sqrt{3} }{4+2\sqrt{3}-2\sqrt{3}-3 }\\\\Simplifying\ the\ expression:\\\\ =\frac{10+5\sqrt{3} }{1}\\\\= 10+5\sqrt{3}[/tex]

Hence: 5 / (2 - √3) = [tex]10+5\sqrt{3}[/tex]

Answer:

y= 3/2x-3

Step-by-step explanation:

m= y2-y1/x2-x1

m= -6-(-9)/-4-(-2)

m= 3/2

y= mx+b

y= 3/2x+b

-9=3/2*-6+b

Answer:

The cost of each:

1 cheese slice = c = $3.75

1 pepperoni slice = p = $2.5

Step-by-step explanation:

Let the cost:

1 cheese slice = c

1 pepperoni slice = p

Two friends are going to the mall to buy pizza.

One of the friends buys 1cheese slice and 2 pepperoni slices for $8.75.

c + 2p = $8.75.....Equation 1

c = $8.75 - 2p

Her friend purchases 2 chese slices and 3 pepperoni slices for $15.00.

2c + 3p = $15.00.....Equation 2

We substitute 8.75 - 2p for c in Equation 2

2(8.75 - 2p) + 3p = $15.00

17.5 - 4p + 3p = 15

Collect like terms

- 4p + 3p = 15 - 17.5

-p = -2.5

p = $2.5

c = $8.75 - 2p

c = $8.75 - 2(2.5)

c = $8.75 - 5.0

c = $3.75

The cost of each:

1 cheese slice = c = $3.75

1 pepperoni slice = p = $2.5

Answer:

Step-by-step explanation:

We can get the answer in the following way:

Answer: y= 0.50x + 40

Step-by-step explanation:

Answer:

h = 15.13 cm

Step-by-step explanation:

Lateral Surface Area of a Cone

Given a right circular cone of base radius r and height h, the lateral surface area is given by:

[tex]A=\pi r\sqrt{r^2+h^2}[/tex]

We are given the lateral area of a funnel as A=236.64 square cm and the radius is r=4.75 cm. It's required to find the height of the cone. It can be calculated by solving for h.

Squaring:

[tex]A^2=\pi^2 r^2(r^2+h^2)[/tex]

Dividing by [tex]\pi r^2[/tex]

[tex]\displaystyle \frac{A^2}{\pi^2 r^2}=r^2+h^2[/tex]

Subtracting [tex]r^2[/tex]:

[tex]\displaystyle \frac{A^2}{\pi^2 r^2}-r^2=h^2[/tex]

Taking square root:

[tex]\displaystyle h=\sqrt{ \frac{A^2}{\pi^2 r^2}-r^2}[/tex]

Substituting the values:

[tex]\displaystyle h=\sqrt{ 251.472-22.5625}[/tex]

[tex]\displaystyle h=\sqrt{ 228.909}[/tex]

h = 15.13 cm

Answer: 25

Step-by-step explanation:

Since Ade uses 2 cups of flours for 5 mini loaves, it simply means that 1 cup of flour will be used for:

= 5/2 = 2.5 mini loaves

Therefore, the number of mini-loaves that he could make with 10 cups of flour would be:

= 10 × 2.5

= 25 mini loaves

Answer:

0.57 inches was left

Step-by-step explanation:

Here, we start by calculating the total length of the yam they have

Mathematically, that will be 0.37 + 0.45 = 0.82 inch

Now, to get what is remaining, we subtract what was borrowed

Mathematically, that is 0.82-0.25 = 0.57 inches
