The difference of 16 and a number, divided by 2

Answer:

14 cupcakes

Step-by-step explanation:

40 percent of 35 is 14

Answer:

14 cupcakes had sprinkles.

Step-by-step explanation:

Write 40% as 40/100. Since finding the fraction of a number is the same as multiplying the fraction with the number, we have 40/100 of 35 = 40/100 × 35.

Answer:

[tex]2p(7p = 7) \\ 14 {p}^{2} = 14p \\ 14 {p}^{2} - 14p = 0[/tex]

Answer:

  PS ≈ 6.08

Step-by-step explanation:

All of the side lengths are given except PS. It can be found using the Law of Cosines, twice.

The first use of the Law of Cosines will be to find the cosine of the angle at X.

  QR² = QX² +RX² -2(QX)(RX)cos(X)

  cos(X) = (QX² +RX² -QR²)/(2·QX·RX) = (8² +10² -4²)/(2·8·10) = 37/40

__

Now, the Law of Cosines can be used to find PS:

  PS² = PX² +SX² -2(PX)(SX)cos(X)

  PS² = 16² +15² -2(16)(15)(37/40) = 37

  PS = √37 ≈ 6.083

The length of PS is about 6.08 units.

Answer:

A. Determine 1% of 56, both of them

Step-by-step explanation:

Percent is count of number per 100 numbers. The total amount Ms Clark pays including the tip is given by: Option B: $36.60

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

It is given that:

Total cost that Ms Clark pays = Cost of meal + tip amount

Now, tip amount is 20% of $25.50

It is calculated as:

[tex]Tip = \dfrac{25.50}{100} \times 20 = 5.1\text{\:(In dollars)}[/tex]

Thus, tip amount = $5.1

And thus, Total cost that Ms Clark pays = $25.5 + $5.1 = $30.6

Thus,

The total amount Ms Clark pays including the tip is given by: Option B: $36.60

The length of the diagonal AC is equal to the length of the diagonal BD,

which is 8×10 - 32 = 48.

Response:

The given parameters are;

The diagonals of the rectangle are AC and BD

The point of intersection of the rectangle = Point E

AE = 2·x + 4

BD = 8·x - 32

Required:

The length of AC

Solution:

The diagonals of a rectangle bisect each other and have equal length.

Therefore;

AE = [tex]\mathbf{\frac{1}{2}}[/tex] × BD

Which gives;

[tex]2 \cdot x + 4 = \mathbf{\dfrac{1}{2} \times \left(8 \cdot x - 32\right)}[/tex]

2·x + 4 = 4·x - 16

4·x - 2·x = 4 + 16 = 20

2·x = 20

[tex]x = \dfrac{20}{2} = 10[/tex]

x = 10

AC = 2 × AE

The ball will hit the ground 5 seconds after being thrown.

Step-by-step explanation:

The correct function is: h(t)= -16t^2+64t+80

You can rewrite the Quadratic function given in the exercise with making h(t)=0. Then this is:

0= -16t^2+64t+80

Now you can simplify the equation dividing both sides by -16. So you get:

0= t^2-4t-5

To find the solution of the Quadratic equation, you can factor it. In order to do this, it is necessary to find two numbers whose sum is -4 and whose product is -5. These number would be -5 and 1.

Therefore, you get this result:

0= (t-5) (t+1)

t1=5

t2=-1

Since the time cannot be negative, you can conclude that the ball will hit the ground 5 seconds after being thrown.

For the path of a ball being thrown maximum height is 144 units, time taken to reach maximum height is 2 units and time, it take to hit the ground is 5 units.

Projectile motion is the motion of the body, when it is thrown in the air taking the action of gravity on it.

The path of a ball being thrown off a building can be modeled by the equation

[tex]y= -16t^2+64t+80[/tex]

Comparing this equation, with standard form of quadratic equation, we get,  a=-16, b=64 and c=80.

Thus, the maximum height time can be given as,

[tex]t=-\dfrac{b}{2a}\\t=-\dfrac{64}{2(-16)}\\t=2\rm sec[/tex]

Thus, the time taken to reach maximum height is 2 seconds.

Again by the equation,

[tex]y= -16t^2+64t+80[/tex]
As it reaches maximum height after the 2 seconds. Therefore,

[tex]y_{max}= -16(2)^2+64(2)+80\\y_{max}= 144\rm[/tex]

This can be find out with the following formula,

[tex]t=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\dfrac{-64\pm\sqrt{64^2-4(-16)(80)}}{2(-16)}\\t=\dfrac{-64\pm96}{-32}\\[/tex]

Taking negative sign,

[tex]t=\dfrac{-64-96}{-32}=5\\[/tex]

Taking positive sign,

[tex]t=\dfrac{-64+96}{-32}=-1\\[/tex]

Thus the time, it take to hit the ground is 5 units.

80 is the constant coefficient of the equation, which represent the height in the feet.

Hence, for the path of a ball being thrown maximum height is 144 units, time taken to reach maximum height is 2 units and time, it take to hit the ground is 5 units.

Answer:

  7

Step-by-step explanation:

The order of operations tells you to start any evaluation by looking at the innermost set of parentheses first.

Here, that means your first step is to find the value of h(-3). You do that by finding the input (x) value -3 in the table for h(x), and locating the corresponding output, h(x), which is 2.

Now, the problem becomes evaluating g(2).

You do the same thing for that function: locate the input x=2 in the table for g(x) and find the corresponding output: 7.

Now, you know ...

The ratio of the height of the model to the height of the actual ATT Building is 0.00814

An equation is an expression used to show the relationship between two or more variables and numbers.

12 inches = 1 ft.

Height of model = 60 inches = 60 inches * 1 ft per 12 in = 5 ft.

Height of  ATT Building = 614 ft.

Ratio of the height of the model to the height of the actual ATT Building = 5 ft / 614 ft = 0.00814

Step-by-step explanation:

area of a trapezoid :

[tex]A = \frac{a+b}{2} h[/tex]

where a and b = length of bases and h = height

here, we are given the area, the length of one base and the height

we want to find the other base length

we can do this by plugging in what we are given and then solving for the unknown variable

first lets define our known variables

Area (A) = 42 , height (h) = 4 and length of one of the bases (a) = 9

we then plug this into the formula and solve for b, the other base length

recall formula : [tex]A = \frac{a+b}{2} h[/tex]

A = 42 , h = 4 , a = 9

[tex]42 = \frac{9+b}{2} 4[/tex]

now solve for b

divide both sides by 4

[tex]10.5=\frac{9+b}{2}[/tex]

multiply both sides by 2

21 = 9 + b

subtract 9 from both sides

12 = b

the other base length is 12

Step-by-step explanation:

with "and" you mean "+" ?

if so, then

3 + 0.75x = 10 + 0.25x

you know that it is perfectly OK to add or subtract the same number to/from both sides of the equation ?

the same for multiplication and division.

the important thing is to do always the same thing to both sides.

1. subtracting 3 from both sides

0.75x = 7 + 0.25x

2. subtracting 0.25x from both sides

0.5x = 7

x = 7/0.5 = 7 / 1/2 = 7 × 2/1 = 14

Answer:

y= ⅗x +1

Step-by-step explanation:

Given line: y= ⅗x +4

Gradient= ⅗

The gradient of the line can be found from the coefficient of x. This applies only when the equation is in the slope-intercept form (y= mx +c).

In the slope-intercept form, the coefficient of y is 1 and all the other terms and constant is on the right-hand side of the equation while the y term is on the left-hand side.

Parallel lines have the same gradient. Thus the line parallel to y= ⅗x +4 would have the equation of y= ⅗x +c, where c is the y-intercept.

To find the value of c, substitute a pair of coordinates into the equation.

Given that the line passes through (-5, -2), we can substitute this coordinates into y= ⅗x +c.

When x= -5, y= -2,

-2= ⅗(-5) +c

-2= -3 +c

c= -2 +3

c= 1

Thus, the equation of the line is y= ⅗x +1.
