Answer:
speed= 60km/h
Step-by-step explanation:
Given data
Distance= 180kilometers
Time= 3 hours
We know that the expression for the speed is
Speed= distance/time
Speed= 180/3
Speed= 60 km/h
Hence the answer is speed= 60km/h
Scarlett needs to order 6,318 binder clips for an upcoming conference. If the binder clips come in
boxes of 39, how many boxes should Scarlett order?
boxes
Answer: 162
Step-by-step explanation:
Divide 6,318 divided by 39 and you get 162.
Plus why defuk she need that manny binder clip. Does she eat them
Answer:
6318 / 39 = 162 boxes.
This question does not really make sense because you ask how many boxes are needed, then say that the clips are coming in 39 boxes.

Los ingresos de Mary en 2019 fueron un 20 por ciento mayores que sus ingresos en 2018. ¿Cuál es la relación entre los ingresos de Mary en 2019 con respecto a sus ingresos en 2018?
a) 1 a 5
b) 5 a 6
c) 6 a 5
d) 5 a 1
e) 20 a 1
Answer:
La respuesta correcta es la opción d) 5 a 1.
Step-by-step explanation:
Para calcular la relación entre los ingresos de Mary en 2019 ([tex]I_{2019}[/tex]) con respecto a sus ingresos en 2018 ([tex]I_{2018}[/tex]), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:
[tex]I_{2019} = 20\% \: I_{2018}[/tex]
[tex] I_{2019} = \frac{20}{100}I_{2018} [/tex]
[tex] \frac{100}{20}I_{2019} = I_{2018} [/tex]
[tex] 5I_{2019} = I_{2018} [/tex]
Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.

Suppose you have two 3 by 3 matrices ,say A and B How can the square of the A and B be mathematically expressed a).AB² b).[AB]² Which one the two is correct?
Answer:
[tex][AB]^2[/tex]
Step-by-step explanation:
Given
Matrices A and B
Required
Represents the square of A and B
The interpretation of the question is that:
The square of the product of A and B
This can be represented as:
The square(product of A and B)
Product means *
So, we have:
The square(A * B)
The square means ^2
So, we have:
[tex][A * B]^2[/tex]
This gives:
[tex][AB]^2[/tex]
Hence, the second option is correct

A magazine contains fourteen pages. You open to a random page.
Find the probability that the page number is 3 or 7.
“Or” meaning they want both. Since they each represent 1/14 add them together. 1/14+1/14=2/14. Then simplify 2/14 to get 1/7
So, the answer the 1/7
What are the coordinates of Rx=3(G)?
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

The surface of a pedestrian bridge forms a parabola. Let the surface at one side of the bridge be represented by (4,0) and the surface at the other side be represented by (8,0). The center of the bridge is 3 feet higher than each side and can be represented by a vertex of (6,3). Write a function in vertex form that models the surface of the bridge.
Answer:
y = -3/4(x - 6)^2 + 3
Step-by-step explanation:
y = ax^2 + bx + c
(4, 0)
16a + 4b + c = 0 Eq. 1
(8, 0)
64a + 8b + c = 0 Eq. 2
(6, 3)
36a + 6b + c = 3 Eq. 3
We have a system of three equations in three variables.
Eq. 2 - Eq. 1
48a + 4b = 0 Eq. 4
Eq. 2 - Eq. 3
28a + 2b = -3 Eq. 5
Eq. 4 - 2 * Eq. 5
-8a = 6
a = -6/8
a = -3/4
48a + 4b = 0
48(-3/4) + 4b = 0
4b = 36
b = 9
16a + 4b + c = 0
16(-3/4) + 4(9) + c = 0
-12 + 36 + c = 0
c = -24
The equation of the parabola is
y = -3/4 x^2 + 9x - 24
y = -3/4(x^2 - 12x + 32)
y = -3/4(x^2 - 12x + 36) + (-3/4)32 - (-3/4)(36)
y = -3/4(x^2 - 12x + 36) -24 + 27
y = -3/4(x - 6)^2 + 3
Determine area of polygon with side length of 10
please help !! thank you so much!!
Step-by-step explanation:
we know that:
[tex]tan(x - y) = \frac{tanx - tany}{1 + tanx \times tany} [/tex]
using this, we can see that x = 73 and y = 13
using this, tan(x-y) = tan(73-13) = tan(60)
therefore, A = 60
we know that tan(60) = √3
therefore, B = 3

Tanya paints the walls of her family room.
The room measures 3 m by 4 m by 7 m.
The walls need 2 coats of paint. A 4-L can of paint covers 40 m².
a) How much paint should Tanya buy?
Answer:
6.1
Step-by-step explanation:
Surface area of the room = 2(lw + hl + hw)
Where,
l = length = 7 m
w = width = 4 m
h = height = 3 m
Surface area of the room = 2(lw + hl + hw)
= 2(7*4 + 3*7 + 3*4)
= 2(28 + 21 + 12)
= 2(61)
= 122 m²
A 4-L can of paint covers 40 m²
Number of 4-L can of paint needed for 1 coat = 122 m² / 40 m²
= 3.05 4-L can of paint
The walls need 2 coats of paint
Number of 4-L can of paint needed for 2 coats = Number of 4-L can of paint needed for 1 coat × 2
= 3.05 × 2
= 6.1 4-L can of paint

Answer:

Step-by-step explanation:
We can graph this line using the equation given to us. The equation is in slope-intercept form, [tex]y=mx+b[/tex]. In this form, [tex]m[/tex] = slope and [tex]b[/tex] = the y-intercept.
So, we can tell that the slope is -[tex]\frac{1}{5}[/tex] and the y-intercept is (2,0).
We begin by plotting on the graph the y-intercept, (2,0).
The slope also equals the [tex]\frac{rise}{run}[/tex]. The slope is negative, so the line will slope down. From the point we have plotted, we will rise negative 1 unit. This means to move down 1 unit. From this point, we will run 5 units. Because the line is negative, we will move 5 units to the left, not the right. We land on point (5,1).
Now, we will draw a line from these two points. This is the line shown in the equation.
Good luck ^^

What is the MEDIAN of the data - (12, 8, 6, 12, 16, 12) *
Answer:
12
Step-by-step explanation:
Median basically means middle. So when you get a set of numbers, put them in order from least to greatest. This leaves us with ( 6 8 12 * 12 12 16 ). Now, we have to find the middle number (shown by *), but because this is an even amount of numbers (no defined middle), we take the two numbers in the middle, which would be the two 12's. If these were different numbers, we would add them together and then divide by two to get the median, but that's unnecessary here. Your median will be 12!
Answer:
When finding median, first arrange the values in ascending or descending order.
Suppose I take the ascending order:
[tex]6 \: \: 8 \: \: 12 \: \: 12 \: \: 12 \: \: 16 \\ median = ( \frac{n}{2} + 1) ^{th} value \\ n = number \: of \: terms = 6 \: digits \\ = ( \frac{6}{2} + 1) {}^{th} \: value \\ = 4 {}^{th} value \\ from \: the \: values 4 {}^{th} value = 12 \\ median = 12[/tex]
