Four times Mark's age plus 7 is Destiny's age. Destiny is 51. What is Mark's age?

Answer:

222222222222224.705876

Answer:

42

Step-by-step explanation:

You would substitute B where is needs to go, 7 + 3(5) + 4(5). First multiply 3 x 5 to get 15, and then multiply 4 x 5 to get 20, 7 + 15 + 20. 7 + 15 = 22 + 20 = 42. I hope this helps.

Answer:

62 coins are not nickels. you could just add the pennies, dimes, & quarters. those totals are given. So

29+16+17= 62

or if you want to impress then start with the total and subtract each given coin count

74-29-16-17=12

74-12=62

Answer:

√35i

Step-by-step explanation:

i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.

Answer:

We know that √-1 = i, where "i" is the imaginary unit

± √(-35) = ± √(35) i

Answer:

er i think its 50 ≠ 4

The answer is A

Answer:

200 litres

Step-by-step explanation:

let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is

g = kd[tex]\sqrt{s}[/tex] ← k is the constant of variation

To find k use g = 25, d = 100 and s = 100, then

25 = k × 100 × [tex]\sqrt{100}[/tex] = k × 100 × 10 = 1000k ( divide both sides by 1000 )

0.025 = k

g = 0.025d[tex]\sqrt{s}[/tex] ← equation of variation

When d = 1000 and s = 64, then

g = 0.025 × 1000 × [tex]\sqrt{64}[/tex] = 0.025 × 1000 × 8 = 200

Answer:

Option D

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.

A right angled triangle is a triangle in which one of the angles is 90°. The side opposite the 90° is known as the hypotenuse while the remaining sides is known as the leg. Let us assume a right triangle with legs of a, b and a hypotenuse of c. Then using Pythagoras theorem:

c² = a² + b²

From the options, option d is the correct option.

For option D, the hypotenuse is c and one leg is a. Let x represent the second leg. Hence:

c² = a² + x²

x² = c² - a²

x = √(c² - a²)

Therefore the other leg would be √(c² - a²)

Answer:

A, B, C, and D

Step-by-step explanation:

Answer & Step-by-step explanation:

Let's have

C = Creepers

B = Balloons

1) 6C + 20B = 11.9  

2) 2C + 15B = 6.05

Eliminate

16C + 20B = 11.9 x3  

-2C + 15B = 6.05 x4

18C + 60B = 35.7  

-8C + 60B = 24.2

10C/10 = 11.5/10  

C = 1.15

she has a total of 3000+6300 so far

To find out how much she needs just take the difference

14500-(3000+6300)=5200

Answer:

please continue i'm facinated on were this story goes

Step-by-step explanation:

From the graph, the correct options are given as,
B. Mia left her house 10 minutes before Erick left his house.
D. Erick and Mia arrived at the park at the same time.
E. Erick walked the same distances as Mia during the last 10 minutes.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The graphs show their distances from home over the same 30-minute period as they walked to the park.
From the graph,
It can be concluded that,
Both reach the park at the same time, as the termination point of the curve is the same.
The graph of mia starts after 10 minutes Erick, which implies Mia left her house 10 minutes before Erick left his house. And Erick walked the same distances as Mia during the last 10 minutes as the slope of the last segment of both curves is the same.

Answer:

angles 1 and 6

Step-by-step explanation:

Vertical angles because they share the same Vertex.

One pair of vertical angles in the figure from the options is ∠1 and ∠6.

Vertical angles are angles that are opposite each other at the intersection of two lines. They are also called vertically opposite angles or non-adjacent angles with the same vertex. They have the same angle measurement or size.

Given is a figure, we need to determine the vertical angles in that,

The vertical angles are -

∠2 and ∠5

∠3 and ∠8

∠7 and ∠4

Hence, one pair of vertical angles in the figure from the options is ∠1 and ∠6.

Step-by-step explanation:

A function assigns the value of each element of one set to the other specific element of another set. The correct option is D.

A function assigns the value of each element of one set to the other specific element of another set.

A vertical asymptote is the value of x for which the function is not defined.

The vertical asymptotes that the graph of this function F(x)=2/x(x+1) will be 2 because x(x+1) is of the second degree.

Hence, the correct option is D.

Answer:

D. [tex]-360\,\frac{km}{h}[/tex]

Step-by-step explanation:

Physically speaking, average acceleration ([tex]\bar a[/tex]), measured in kilometers per square hour, is defined by following formula:

[tex]\bar a = \frac{v_{f}-v_{o}}{t_{f}-t_{o}}[/tex] (1)

Where:

[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final speed, measured in kilometers per hour.

[tex]t_{o}[/tex], [tex]t_{f}[/tex] - Initial and final instant, measured in hours.

The initial and final instants are, respectively:

[tex]t_{o} = 5\,min\times \frac{1\,h}{60\,min}[/tex]

[tex]t_{o} = 0.083\,h[/tex]

[tex]t_{f} = 9\,min \times \frac{1\,h}{60\,min}[/tex]

[tex]t_{f} = 0.15\,h[/tex]

If we know that [tex]t_{o} = 0.083\,h[/tex], [tex]v_{o} = 60\,\frac{km}{h}[/tex], [tex]t_{f} = 0.15\,h[/tex] and [tex]v_{f} = 36\,\frac{km}{h}[/tex], then the average acceleration of Kelly is:

[tex]\bar a = \frac{36\,\frac{km}{h}-60\,\frac{km}{h}}{0.15\,h-0.083\,h}[/tex]

[tex]\bar a = -358.209\,\frac{km}{h^{2}}[/tex]
