Answer:

4 seconds

Step-by-step explanation:

Given

[tex]h(t) = -25t + 100[/tex]

Required

Determine what time it hits the ground

When the ball is on the ground, the height is at 0

i.e.

[tex]h(t) = 0[/tex]

Substitute 0 for h(t) in [tex]h(t) = -25t + 100[/tex]

[tex]0 = -25t + 100[/tex]

Collect Like Terms

[tex]25t = 100[/tex]

Solve for t

[tex]t = 100/25[/tex]

[tex]t = 4[/tex]

Hence, the ball will hit the ground in 4 seconds

[tex]1\frac{13}{15}[/tex] is the solution for [tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex]

Fractions represent the parts of a whole or collection of objects.

The given expression is

[tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex]

Firstly we need to convert this mixed fraction to improper fraction.

Improper fractions are fractions whose numerator is greater than denominator.

((15×3)+10)/15 -  ((15×1)+12)/15

(45+10)/15 - (15+12)/15

55/15-27/15

15 is the LCM

(55-27)/15

28/15

Now we convert this to improper fraction

[tex]1\frac{13}{15}[/tex]

Hence [tex]1\frac{13}{15}[/tex] is the solution for [tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex].

m= 120 - 6*d

Step-by-step explanation:

budget is $120 per 1 month, spends $6 per 1 day

on the the table you have 2 columns: one labele it "days" and one "$ spent" and fill it in:  

days: 1,2,3,4,..

$ spent: 6, 6*2=12, 6*3= 18, 6*4= 32,...

on the graph lable the horizontal axis "days" and the vertical axis "$ spent"

now plot the points (1,6), (2,12),(3,18), ..., and draw a line trough them

the equation is

m= 120 - 6*d

so after 20 days for example, out of 120 will have m=120-6*20=120-120=0,

$0 wil have in 20 days

Answer:

Mario would like to ride Hurricane coaster.

Gravity coaster travels at a unit rate of 34 m/s.

Step-by-step explanation:

Distance traveled by Gravity coaster = 340 meters

Time taken by Gravity coaster = 10 seconds

Distance traveled by Hurricane coaster = 190 meters

Time taken by Hurricane coaster = 5 seconds

Unit rate is nothing but the distance traveled by each coaster in unit time.

To find the unit rate, we can use the following formula:

[tex]Speed = \dfrac{Distance}{Time}[/tex]

Unit rate or speed of Gravity coaster = [tex]\frac{340\ m}{10\ s} = 34\ m/s[/tex]

Unit rate or speed of Hurricane coaster = [tex]\frac{190\ m}{5\ s} = 38\ m/s[/tex]

So, the faster coaster is the Hurricane coaster.

Mario would like to ride Hurricane coaster.

Gravity coaster travels at 34 m/s.

Answer:

[tex]y=\frac{9}{4}x-\frac{55}{4}[/tex]

Step-by-step explanation:

Slope-intercept form: y = mx + b

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Given points: (3, -7), (7, 2)

(3, -7) = (x1, y1)

(7, 2) = (x2, y2)

To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.

First, let's find the slope. To do this, input the given points into the slope formula:

[tex]\frac{2-(-7)}{7-3}[/tex]

Simplify:

2 - (-7) = 2 + 7 = 9

7 - 3 = 4

[tex]\frac{9}{4}[/tex]

The slope is [tex]\frac{9}{4}[/tex].

To find the y-intercept, input the slope and one of the given points(in this example I'll use point (7, 2)) into the equation and solve for b:

[tex]2=\frac{9}{4}(7)+b[/tex]

[tex]2=\frac{63}{4}+b[/tex]

[tex]-\frac{55}{4} =b[/tex]

The y-intercept is [tex]-\frac{55}{4}[/tex].

Now that we know the slope and the y-intercept, we can write the equation:

[tex]y=\frac{9}{4}x-\frac{55}{4}[/tex]

Answer:

$52.45

Step-by-step explanation:

the tax is $2.50, if we add that to $49.95 we get $52.45

Total cost will be $52.45.

What is Percentage?

A relative value indicating hundredth part of any quantity is called percentage.

Given that;

Cost of shoes = $49.95

Tax = 5%

Now,

The value of tax = 49.95 × 5%

                         = 49.95 × 5/100

                         = 2.50

So, Total cost =  $49.95 + $2.50

                     = $52.45

Thus, Total cost will be $52.45.

Step-by-step explanation:

Solve for c in x^2 = 441

Taking the square root of both sides x = 21

Now x^3 = 21^3 = 9,261

The answer is 9,261

The solution is x² is to 441 as x³ is to 9261

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

x² = 441

Taking square roots on both sides , we get

x = 21

Therefore , x³ = 21 × 21 × 21

x³ = 9261

Hence , x² is to 441 as x³ is to 9261

∵ In the rhombus, all the sides are equal in length

∵ MNOP is a rhombus

∵ MN = NO = OP = PM

∵ MN = 9x - 77

∵ OP = 3x + 7

→ Equate them to find x

∴ 9x - 77 = 3x + 7

→ Add 77 to both sides

∴ 9x = 3x + 84

→ Subtract 3x from both sides

∴ 6x = 84

→ Divide both sides by 6

∴ x = 14

→ Substitute the value of x in the expression of OP to find its length

∵ OP = 3(14) + 7 = 42 + 7

∴ OP = 49

∵ All the sides are equal in length

∴ MP = 49

∵ The diagonals of the square bisect each other

∵ STUV is a square

∵ SU and TV are its diagonals

∴ W is the mid-point of SU and TV

∴ SW = WU

∵ SW = 2x + 13

∵ WU = 8x - 41

→ Equate them to find x

∴ 8x - 41 = 2x + 13

→ Add 41 to both sides

∴ 8x = 2x + 54

→ Subtract 2x from both sides

∴ 6x = 54

→ Divide both sides by 6

∴ x = 9

→ Substitute x in the expression of SW to find it

∵ SW = 2(9) + 13 = 18 + 13

∴ SW = 31

∵ SU = SW + WU

∵ SW = WU

∴ SU = 31 + 31 = 62

∵ Diagonals of the square are equal in length

∴ SU = VT

∴ VT = 62
