Answer:
24 : 84 = 2 : 7
Step-by-step explanation:
We can simplify the ratio 24 : 84 by dividing both terms by the greatest common factor (GCF).
The GCF of 24 and 84 is 12.
Divide both terms by 12.
24 ÷ 12 = 2
84 ÷ 12 = 7
Therefore:
24 : 84 = 2 : 7

Dave earns 7.50 per hour and has deductions if 36 per week, If Dave works 40 hours per werk, what will his next pay be for 1 week.
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)

Therefore, Dave's next pay for 1 week will be $264.
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. if sergio spends at least 70 dollars he will recieve free shipping on his order. write and inequality to determine how much sergio needs to spend on each gift to order to receive free shipping
[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.
What is inequality?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

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

Use the figure to the right to find the value of PT. T is the midpoint of PQ.
PT = 5x +2 and TQ = 7x-6
PT=
(Simplify your answer.)
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.

M is the midpoint of ST. S(-8, 9) and M(-10, 14). Find the coordinates of the other endpoint, T.
Answer:
T = (-12, 19)
Step-by-step explanation:
We know that the definition of the midpoint is ...
M = (S + T)/2
Solving for T gives ...
T = 2M -S
T = 2(-10, 14) -(-8, 9) = (-20+8, 28-9)

You plan to rent a car from XYZ Car Rental Company for a flat rate of $35 a
day. If you plan to use the car for 3 days or fewer, you must also pay a $10
insurance fee per day. If you plan to use the car for more than 3 days, there is
a $5 insurance fee per day. Write a piecewise-defined function that models this
function.
Thanks for any help!
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]
A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?
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.

Nina is training for a marathon. She can run 4 1/2 kilometers in 1/3 of an hour. At this pace, how many kilometers can Nina run in 1 hour
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

A [0.65)
B. [65,00)
C. (0.65)
D. (65.00)
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:

En un supermercado tienen dos contadores eléctricos de flujo de personas 1 registra de 3 en 3 y el otro de 5 en 5 en el momento que ambos se detienen unos señala de 840 y el otro de 560 diga Cuál de los dos es el que marca de 3 en 3?
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.
7/60=5/24w+11/12 please help!!!!
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.
How do we solve an equation?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.

A wildlife habitat houses 41 animals. There are three more reptiles than mammals in the habitat. There are seven fewer amphibians than mammals in the habitat. How many amphibians are there in the habitat?
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
