Answer:

A and H are correct

Step-by-step explanation:

I took the quiz

The expression for the given statement is n³/16-2+8. Therefore, the options A and H are correct answer.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

The given statement is “two less than the quotient of a number cubed and sixteen, increased by eight”

"Two less than x" describes "x- 2"

"Quotient of x and y" describes  x/y

"x increased by y" describes x+y

n³/16 is the quotient and 2 is subtracted and 8 is increased which means 8 is added.

So, the expression is n³/16-2+8

= n³/16 +6

When n=4, we get

4³/16 +6

= 4+6

= 10

Therefore, the options A and H are correct answer.

Answer:

1 1/2 cups of vinegar

Step-by-step explanation:

Baxter has a recipe for salad dressing that calls for 2/3 cup olive oil, 1/4 cup vinegar, and 4/3 cup puréed avocado. How much vinegar does baxter need to make 6 cups of dressing?

1 cup of dressing = 1/4 cup vinegar

6 cups of dressing = x

Cross Multiply

1 × x = 6 × 1/4

x = 6/4

x = 1 1/2 cups of vinegar

Answer: 1. -8, 2. 44, 3. 14, 4. 251, 5. -113, 6. -108, 7. -9

Step-by-step explanation: To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

Answer:

41 feet

Step-by-step explanation:

the biggest number will always be the hypotenuse, because it is a right trangle.

Answer:

41 feet

Step-by-step explanation:

Pythagorean theory: 9squared+40squared=41squared

Answer:

As i understand, you put an egg inside a container, and then you drop it from 30ft above the ground.

Now, when the container is in the air, the only force acting on it will be the gravitational force (we can discard things like the air resistance, as we do not know the shape or volume of the container).

The gravitational acceleration is g = 32.2ft/s^2

Then the acceleration of the container will be:

A(t) = -32.2ft/s^2

For the velocity, we need to integrate over time to get:

V(t) = (-32.2ft/s^2)*t + v0

where v0 is the initial velocity, as the container is "dropped", the initial velocity is zero, then:

V(t) = (-32.2ft/s^2)*t

For the position, or height in this case, we integrate again over time, and get:

P(t) = (1/2)*(-32.2ft/s^2)*t^2 + p0

Where p0 is the initial height, 30 ft in this case.

Then the equation for the height, as a function of time, is:

P(t) = (-16.1ft/s^2)*t^2 + 30ft.

Where the fact that the container is made in such a way that an egg inside of it does not break (For example, made of a really dense and elastic material that can absorb all the energy of the impact), does not change anything in this equation, as the kinematics do not depend on that kind of properties.

Answer:

Answer:

Silk = x = 1.5 yards

Cotton = y = 2.75 yards

Step-by-step explanation:

x + y = 4.25

16.90x + 4y = 36.35

1. The solution to the equation represent number of yards of silk and number of yards of cotton bought.

2.

x + y = 4.25 (1)

16.90x + 4y = 36.35 (2)

Multiply (1) by 4

4x + 4y = 17 (3)

16.90x + 4y = 36.35 (2)

Subtract (3) from (2)

16.90x - 4x = 36.35 - 17

12.90x = 19.35

Divide both sides by 12.90

x = 19.35 / 12.90

= 1.5

x = 1.5 yards

Substitute x = 1.5 yards into (1)

x + y = 4.25

1.5 + y = 4.25

y = 4.25 - 1.5

= 2.75

y = 2.75 yards

Silk = x = 1.5 yards

Cotton = y = 2.75 yards

Answer:

[tex]\displaystyle y =\frac{1}{2}x+5[/tex]

Step-by-step explanation:

Equation of the line

The slope-intercept form of a line is given by:

[tex]y=mx+b[/tex]

Being:

m = the slope of the line

b = the y-intercept

We can also use the point-slope form of the line:

[tex]y - k=m(x-h)[/tex]

Being:

(h,k) = A point that belongs to the line

Two lines of slopes m1 and m2 are perpendicular if:

[tex]m_1.m_2=-1[/tex]

We are given the line:

[tex]y=-2x+5[/tex]

Whose slope is m1=-2

Thus, the perpendicular line has a slope of:

[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]

[tex]\displaystyle m_2=-\frac{1}{-2}[/tex]

[tex]\displaystyle m_2=\frac{1}{2}[/tex]

The required line contains the point (-8,1), thus the equation is:

[tex]\displaystyle y - 1=\frac{1}{2}(x+8)[/tex]

Removing the parentheses:

[tex]\displaystyle y - 1=\frac{1}{2}x+\frac{1}{2}\cdot 8[/tex]

Adding 1:

[tex]\displaystyle y =\frac{1}{2}x+\frac{1}{2}\cdot 8+1[/tex]

Operating:

[tex]\displaystyle y =\frac{1}{2}x+4+1[/tex]

[tex]\mathbf{\displaystyle y =\frac{1}{2}x+5}[/tex]

Answer:  Clara's body eliminated the antibiotic at the same rate as Heidi's body.

Step-by-step explanation:

1) Let's write the data of Clara's table just to have them ready to compare

t (hours)          1               2               3             4               5

f(t) (mg)         236.5    223.73      211.65     200.22       189.41

Change(mg)     -          -12.77       -12.05     -11.43      -10.81

2) Now calculate the amount of medicine as per Heide's formula, 300(0.946)^t:

t (hours)             1             2                 3             4               5

f(t) (mg)           283.8    268.48         253.98     240.26      227.29

Change (mg)                 -15.12          -14.5     -13.72          -12.97

Now you can compare the data and realize that the rate of change of Heide is greater than the rate of change of Clara, meaning that Heide eliminates the medicine faster than Clara.

Answer: a) x = 5   b) x = 12

Step-by-step explanation: For each one you just do the inverse to get it on the other side of the equal sign. For example x + 3 = 8 would be like this :

1. x + 3 = 8

2. x + 3 - 3 = 8 -3

    ( + 3 - 3 cancels out)

3. x = 5

a. x + 3 = 8

x = 8 - 3

x = 5

b. x - 5 = 7

x = 7 + 5

x = 12

Answer:

The perimeter of the triangle is approximately equal to 18

Step-by-step explanation:

The coordinates of the vertices of the triangle are (-3, -1), (2, 3), and (5, 2)

The formula for the lengths, l, of the sides of the triangle, given their end points coordinates is presented as follows;

[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

The lengths of the segments that make up the triangle are therefore;

Between the vertex points (-3, -1) and (2, 3), we have, √((-3 - 2)² + (-1 - 3)²) = √41

Between the vertex points (-3, -1) and (5, 2), we have, √((-3 - 5)² + (-1 - 2)²) = √73

Between the vertex points (2, 3) and (5, 2), we have, √((2 - 5)² + (3 - 2)²) = √10

Therefore;

The perimeter of the triangle = The sum of the lengths of the sides of the triangle =  √41 + √73 + √10

The perimeter of the triangle = √41 + √73 + √10 ≈ 18.1094

∴ The perimeter of the triangle ≈ 18, after rounding to the nearest whole number.

Answer:

3.78 because u subtract 17.22 from 21

Answer: Please make your question clearer next time.

n= 3.78

Step-by-step Explanation:

Subtract 17.22 from both sides of the equation.

n + 17.22=22

n + 17.22 - 17.22 = 21 - 17.22

Simplify: 21 - 17.22= 3.78, Therefore n= 3.78.

Answer:

12.5 m

17.5 m

20 m

Step-by-step explanation:

Scale of the drawing to the actual size of the field = 24 mm : 5 m

✍️Given an actual length of 96 mm, actual length would be x m.

Thus:

24 mm : 5 m = 96 mm : x m

[tex] \frac{24}{5} = \frac{96}{x} [/tex]

Cross multiply

[tex] 24x = 96*5 [/tex]

[tex] 24x = 480 [/tex]

Divide both sides by 24

[tex] x = \frac{480}{24} [/tex]

✅[tex] x = 20 m [/tex]

✍️Given an actual length of 84 mm, actual length would be x m.

Thus:

24 mm : 5 m = 84 mm : x m

[tex] \frac{24}{5} = \frac{84}{x} [/tex]

Cross multiply

[tex] 24x = 84*5 [/tex]

[tex] 24x = 420 [/tex]

Divide both sides by 24

[tex] x = \frac{420}{24} [/tex]

✅[tex] x = 17.5 m [/tex]

✍️Given an actual length of 60 mm, actual length would be x m.

Thus:

24 mm : 5 m = 60 mm : x m

[tex] \frac{24}{5} = \frac{60}{x} [/tex]

Cross multiply

[tex] 24x = 60*5 [/tex]

[tex] 24x = 300 [/tex]

Divide both sides by 24

[tex] x = \frac{300}{24} [/tex]

✅[tex] x = 12.5 m [/tex]
