How is this solved..? Plz help

Answer:

{0, 65]

Step-by-step explanation:

A function shows the relationship between two variables (an independent and dependent variable). The independent variable is not dependent on other variables, it is considered as the input while the dependent variable is dependent on other variables and considered as output.

The speed of Marcus must not be faster than 65 mph, hence speed ≤ 65 mph. This means that Marcus can drive with speed ranging from 0 mph to 65 mph, hence 0 ≤ speed ≤ 65 mph. This is represented using the interval notation:

[0, 65]

Answer:

$264

Step-by-step explanation:

$7.50 * 40 hrs= $300-$36=$264

Answer:

$264 for the week

Step-by-step explanation:

$7.50 per hour for 40 hours (7.50 x 40 = 300)

= $300

Deduction of $36 per week.

$300-$36= $264

Therefore, Dave's next pay for 1 week will be $264.

Answer:

Building to the left is taller.

Step-by-step explanation:

Kindly refer to the attached diagram for the given dimensions.

[tex]\triangle ABR, \triangle PQR[/tex]

AB and PQ be the two buildings.

The car be parked at point R.

[tex]\angle ARB = 50^\circ\ and \\\angle PRQ = 40^\circ[/tex]

Distance of R from building bases:

BR = 49 m

QR = 56 m

Let us use tangent in [tex]\triangle PQR:[/tex]

[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]

[tex]tan40 = \dfrac{h_1}{56}\\\Rightarrow h_1 = 56 \times 0.839 \\\Rightarrow h_1 \approx 47\ m[/tex]

Let us use tangent in [tex]\triangle PQR:[/tex]

[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]

[tex]tan50 = \dfrac{h_2}{49}\\\Rightarrow h_2 = 49 \times 1.19 \\\Rightarrow h_2 \approx 58.4\ m[/tex]

So, building to the left is taller.

Answer:

y=x-6

Step-by-step explanation:

Y=x+3 according to this equation, the gradient is 1 comparing to y=mx+c. so m is the gradient. so from the equation, the coefficient of x is 1. since the line is parallel so it means the new equation has the same gradient m.

y=x+c but it passes through 1,-5...when x= 1, y=-5 from here , we Can find the new intercept c. -5=1+c. so c=-5-1=-6

the new equation y=x-6

Answer: 8

Step-by-step explanation:

Let mammals be represented by y

There are three more reptiles than mammals in the habitat. Therefore, Reptiles = y + 3

There are seven fewer amphibians than mammals in the habitat. Therefore, amphibian = y - 7

y + y + 3 + y - 7 = 41

3y - 4 = 41

3y = 41 + 4

3y = 45

y = 45/3

y = 15

Since amphibian = y - 7

= 15 - 7

= 8

There are 8 amphibians

Answer:

Step-by-step explanation:

w  = -3 and 21/25

The value of w in 7/60=5/24w+11/12 is 6/5.

Given,

7/60 = 5/24 w + 11/12

We need to solve for w.

It depends on the type of equation given.

We need to keep the variable that we are solving for in one side and simplify the other terms.

Find the value of w.

We have,

7/60 = 5/24 w + 11/12

Subtract 11/12 on both sides.

7/60 - 11/12 = 5/24 w + 11/12 - 11/12

7/6 - 11/12 = 5/24 w

Simplify the left-hand side into a fraction.

(14 - 11 ) / 12 = 5 / 24 w

3 / 12 = 5 / 24 w

Multiply 24 / 5 on both sides.

24/5 x 3/12 = 24/5 x 5/24 w

6 / 5 = w

w = 6 / 5

Thus the value of w in 7/60=5/24w+11/12  is 6/5.

Step-by-step explanation:

Answer:

13½ kilometers

Step-by-step explanation:

If Nina runs 4½ km in ⅓ of an hour, at this pace, the number of km she'd run in an hour can be calculated as follows.

Let x be the number of km to run in an hour.

4½km => ⅓ hr

x km => 1 hr

Cross multiply

[tex] 1*4\frac{1}{2} = \frac{1}{3}*x [/tex]

[tex] 4\frac{1}{2} = \frac{x}{3} [/tex]

Multiply both sides by 3

[tex] 4\frac{1}{2}*3 = \frac{x}{3}*3  [/tex]

[tex] \frac{9}{2}*3 = x  [/tex]

[tex] \frac{27}{2} = x [/tex]

[tex] 13\frac{1}{2} = x [/tex]

x = number of km Nina runs in 1 hour = 13½ kilometers

Answer:

The piece-wise function is;

[tex]f\left (x \right ) = \begin{cases} \$ 45 \times x & \text{ if } x \leq 3 \ days \\ \$40 \times x & \text{ if } x > 3 \ days\end{cases}[/tex]

Step-by-step explanation:

The flat rate for renting the car = $35 per day

The amount charged as insurance fee per day for renting the car for 3 days or less = $10

The insurance fee charged per day when the car is rented for more than 3 days = $5

Let the number of days = x

Therefore, we have;

For x ≤ 3, f(x) = 35 × x + 10 × x = x × (35+10) = 45·x

For x > 3, f(x) = 35 × x + 5 × x = x × (35+5) = 40·x

Therefore;

The charge rate for renting the car for less than or equal to 3 days = 45·x

The charge rate for renting the car for more than 3 days = 40·x

The piece-wise function can be presented as follows;

[tex]f\left (x \right ) = \begin{cases} \$ 45 \times x & \text{ if } x \leq 3 \ days \\ \$40 \times x & \text{ if } x > 3 \ days\end{cases}[/tex]

Answer:

El contador que señala 840 registra de 3 en 3.

Step-by-step explanation:

Existe un truco para determinar si un número es múltiplo de 3, si la suma de sus dígitos es 3 o uno de sus múltiplos, entonces el número es un múltiplo de 3. En consecuencia, corresponde al contador eléctrico que registra de 3 en 3 y el otro contador eléctrico sería el que registra de 5 en 5.

Primer contador: 840

[tex]x = 8+4+0[/tex]

[tex]x = 12[/tex]

12 es un múltiplo de 3, por tanto, este contador es el que registra de 3 en 3.

Segundo contador: 560

[tex]x = 5+6+0[/tex]

[tex]x = 11[/tex]

11 no es un múltiplo de 3. Asimismo, todo número que sea múltiplo de 5 termina en 5 o 0, entonces este contador es el que registra de 5 en 5.

El contador que señala 840 registra de 3 en 3.

Step-by-step explanation:

There are 5280 ft per mile, and 12 inches per foot. There are 178.7 inches per Prius. The number needed is ...

  (13233 mi)(5280 ft/mi)(12 in/ft)/(178.7 in/Prius)

  = (13233×5280×12/178.7) Prius

  = 4,691,901.95 Prius

With a little squeezing, you could gain the extra 7.4 inches necessary to round this number to the next higher integer value:

[tex]7.25 \leqslant x[/tex]

Step-by-step explanation:

you do 1.5×8 to see how much shipping cost

you get 12 then subtract 12 from 70 and you get 58, then you do 58÷8 and you get $7.25

so he needs to spend $7.25 or more on each friend. (im pretty sure)

The amount urgio needs to spend on each gift in order to receive free shipping is 7.25.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Given that urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each.

Let the cost of each gift = c

urgio is buying gifts for 8 friends = 8 gifts

Hence, the Inequality equation is written as:

(c + $1.50)× 8 ≥ $70

8c + 12 ≥ 70

8c ≥70 - 12

c ≥ 58/8

c≥ 7.25

Therefore, the amount urgio needs to spend on each gift in order to receive free shipping is 7.25

#SPJ2

Answer:

22

Step-by-step explanation:

Given that T is the midpoint of line PQ, segments PT = 5x + 2, and TQ = 7x - 6 that are formed would be equidistant or congruent. PT = TQ.

Therefore:

[tex] 5x + 2 = 7x - 6 [/tex]

Let's find the value of x

Rearrange the equation, so that the terms having x would be on your left, while those without x would be on your right.

[tex] 5x - 7x = - 2 - 6 [/tex]

[tex] -2x = -8 [/tex]

Divide both sides by -2

[tex] x = 4 [/tex]

Plug in the value of x into the expression, 5x + 2, to find PT.

PT = 5(4) + 2 = 22.

Answer:

  T = (-12, 19)

Step-by-step explanation:

We know that the definition of the midpoint is ...

  M = (S + T)/2

  T = (-12, 19)

The number on rearranging is given by the equation A = 1764 , where the square root of the number is B = 42

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 ,

Let the number be represented as A

Now , the set of numbers is = { 1 , 4 , 6 , 7 }
