Answer: 64 ; $28

Step-by-step explanation:

A. Billy collected 256 conks but lost ¾ of them on his way to school through a hole in his bag. When he arrived at school how many conks did Billy had left?

Number of conks collected by Billy = 256

Fraction lost = 3/4

Amount lost = 3/4 × 256 = 192

Number of conks Billy has left will be:

= 256 - 192

= 64

B. Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?

This will cost:

= 7/9 × $36

= 7 × $4

= $28

Answer:

$57.8

Step-by-step explanation:

Horseshoe ranch charges $12.95 ranch entrance fee

$14.95 is paid per hour to rent the horse

Therefore since Mary is going to rent the horse for 3 hours then the total amount she will spend can be calculated as follows

= $12.95 + $14.95×3

= $12.95 + $44.85

=$57.8

Answer:

The answer is 650

Step-by-step explanation:

You need to find the slope.

i took the points (2, 100) and (4, 200)

Then i put it into the slope formula which is y2 - y1/ x2- x1

I got that the slope is 50. So every two hours 5o millmeters for water drops. So now at 12 hours on the graph it says 600 millimeters of wate has already dropped. The graph is at intervals of two. Now at the next point it will be 14. So just add 50 to 600 and you get 650. So at 14 hours 650 water should have dripped

y=2x-2

Step-by-step explanation:

my work is in the picture I attached. lmk if you'd like me to explain more

Answer:

y = 2x - 2

Step-by-step explanation:

let equation of the line be y = mx + c

since it is parallel to y = 2x + 2, gradient/slope of the two lines would be the same

therefore, m = 2

since it passes through (4, 6),

sub (4, 6):

6 = 2(4) + c

c = -2

therefore equation of the line is y = 2x - 2

Answer:

[tex]4.99\times 10^{-10}\ m[/tex]

Step-by-step explanation:

Given that,

The diameter of a proton is 1.7 x 10⁻¹⁵ meters

The diameter of an atom is 5 x 10⁻¹⁰ meters.

We need to find the difference in the diameters.

[tex]D=5\cdot10^{-10}-1.7\cdot10^{-15}\\\\=4.99\times 10^{-10}\ m[/tex]

So, the difference in the diameter is [tex]4.99\times 10^{-10}\ m[/tex].

Answer:

[tex]y-6=-6(x-1)[/tex]

Step-by-step explanation:

A point-slope equation requires two values in order to write it: one coordinate and the slope.

First, find the slope between the two given points. To find the slope, you would subtract the first Y from the second Y and the first X from the second X. Y goes on top of the fraction bar, making the equation look like this:

[tex]\frac{6-(-6)}{1-3}[/tex]

Then, simplify the slope equation:

[tex]\frac{6-(-6)}{1-3} = \frac{6+6}{1-3} = \frac{12}{-2} = -6[/tex]

The slope is -6.

Finally, choose one of the coordinates. For this, I'll pick (1, 6).

The point-slope equation is [tex]y-y_{1} =m(x-x_{1})[/tex]

So, simply fill in the [tex]m[/tex], [tex]y_{1}[/tex] , and [tex]x_{1}[/tex] spots with the value we have found.

[tex]m[/tex] is the slope, so replace it with -6.

[tex]y_{1}[/tex] = 6

[tex]x_{1}[/tex] = 1

Final answer:

[tex]y-6=-6(x-1)[/tex]

Answer:

= 12x − 10 :)

Step-by-step explanation:

Answer:

The three integers are

11, 13, and 15.

Step-by-step explanation:

. The sum of these is 39, so we can write:

x+(x+2)+(x+4)=39

Open the brackets and simplify.

x+x+2+x=+4=39

3x+6=39

Subtract 6 from each side.

3x=33

Divide both sides by 3.

x=11

Therefore: (x+2)=13 and (x+4)=15

a=associates / p=partners

1a= $800 / 1p= $1500

(6)a + (2)p = 800 x 6 + 1500 + 2 = $7800

(x)a + (y)p = $z

Answer:

x = 15°

Step-by-step explanation:

We know that a triangle totals up to 180° when you add together all the angles. Using that, we can then add up the two angles we already know and solve for x.

106° + 59° = 165°

180° - 165° = 15°

Given:

A recipe calls for a total of 3 and two-thirds cups flour and sugar respectively.

To find:

The flour needed if the recipe calls for one-fourth cup of sugar.

Solution:

According to the question,

[tex]\dfrac{2}{3}[/tex] of sugar needs 3 cups of flour.

[tex]1[/tex] of sugar needs [tex]\dfrac{3}{2}\times 3[/tex] cups of flour.

[tex]\dfrac{1}{4}[/tex] of sugar needs [tex]\dfrac{1}{4}\times \dfrac{3}{2}\times 3[/tex] cups of flour.

Now,

[tex]\text{Required flour}=\dfrac{1}{4}\times \dfrac{3}{2}\times 3[/tex]

[tex]\text{Required flour}=\dfrac{9}{8}[/tex]

Therefore, the required flour is [tex]\dfrac{9}{8}[/tex] cups.
