Answer:
13/6
Step-by-step explanation:
slope = (y2-y1)/(x2-x1) where the variables indicate the coordinates of the two points
slope = (-7-6)/(-5-1) = -13/-6 = 13/6
If it takes Laine 4 hours to wash the windows, Leslie 5 hours to wash the same windows, and Lance 6 hours to wash the windows, how long would it take them all working together?
.8 hours
6 hours
1.6 hours
3.2 hours
1/4+1/5+1/6=1/x
LCM = 60
15/60+12/60+10/60=1/x
37/60=1/x
37x=60
x=60/37=1.62, round =1.6
1.6 HOURS
The number of hours they would take them all working together is around 1.6 hours.
What are ratios and proportions?A ratio is the divide of the two variables and the lower variable known as the denominator should not be zero.
Given that laine takes 4 hours to complete work
In 1 hour Laine will do 1/4 part of the work.
In 1 hour Leslie will do 1/5 part of the work.
In a 1-hour Lance will do 1/6 part of the work.
so let's suppose all done work by x hours then
1/4 + 1/5 + 1/6 = 1/x
x =1.6 so all together done the work by 1.6 hours.

A postal service offers flat-rate shipping for mail in special boxes. Today, Ahmed shipped 1
small box and 6 medium boxes, which cost him 360 dirhams to ship. Meanwhile, Sarah
shipped 3 small boxes and 6 medium boxes, and paid 420 dirhams.
a) Write a system of equations that represents Ahmed and Sara's purchases.
Answer:
Ahmed:
x + 6y = 360
Sarah:
3x + 6y = 420
Step-by-step explanation:
Let
Cost of the small box = x
Cost of the medium box = y
Ahmed:
x + 6y = 360
Sarah:
3x + 6y = 420
x + 6y = 360 (1)
3x + 6y = 420 (2)
Eliminate y by subtracting (1) from (2)
3x - x + 6y - 6y = 420 - 360
2x = 60
x = 60/2
x = 30
Substitute x = 30 into (1) to find y
x + 6y = 360
30 + 6y = 360
6y = 360 - 30
6y = 330
y = 330/6
y = 55
Cost of the small box = x = 30 dirhams
Cost of the medium box = y = 55 dirhams

5. What might be the dimensions of a
cylindrical container that holds 750 mL
of juice?
Answer:
radius of 10.9254843 and height of 10.9254843
Step-by-step explanation:
The equation for the volume of a cylinder is V = 2 pi r h
If V (volume) = 750, find for r and h
(I'm just going to make the radius and height the same thing)
750 = 2 pi r r
375 = pi r^2
119.366207 = r^2
10.9254843 = r

Answer:
La temperatura en estos momentos es -2 grados centígrados.
Step-by-step explanation:
Dado que conoces que había una temperatura de 8°C y que a las 22 horas esta ha bajado unos 10 grados, tienes que restar estos 10 grados de la temperatura inicial para saber cuál es la temperatura actual:
8-10=-2
De acuerdo a esto, la respuesta es que la temperatura en estos momentos es -2 grados centígrados.
A breakfast chef used different amounts of milk when making pancakes, depending on the number of pancakes ordered. The results are shown below. What is the average amount of milk used for an order of pancakes.
Answer:
1/2c
Step-by-step explanation:
A breakfast chef used different amounts of ill when
making pancakes, depending on the number of panes ordered. The results are shown below.
1/2c, 1/4c, 1/2c, 3/4c, 1/2c, 3/4c, 1/2c, 1/4c, 1/2c, 1/2c
What is the average amount of milk used for an order of pancakes?
Average amount of milk used for an order of pancakes = {1/2c + 1/4c + 1/2c + 3/4c + 1/2c + 3/4c + 1/2c + 1/4c + 1/2c + 1/2c} ÷ 10
= {6(1/2c) + 2(1/4c) + 2(3/4c)} ÷ 10
= {6/2c + 2/4c + 6/4c} ÷ 10
= {3c + 1/2c + 3/2c} ÷ 10
= {(6+1+3) / 2}c ÷ 10
= 10/2c ÷ 10
= 5c ÷ 10
= 5/10c
= 1/2c
The average amount of milk used for an order of pancakes = 1/2c

What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
|AC|^2 = |AB|^2 + |BC|^2
By applying Pythagoras theorem In right triangle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
(720 + J)² = (648)² + J²
518400+ J² + 1440J = 419904 + J²
1440J = 518400- 419904
J = 76
Therefore, J = 76 units is the answer.

2. Find measure of arc AB.
Find mAB
A) 68
B) 78
C) 88
D) 98
Answer:
C) 88
Step-by-step explanation:
so we are given a circle, and m<ACB is 44°. We need to find the measure of arc AB
<ACB is an inscribed angle (it is inside the circle), and it intercepts the arc AB
Inscribed angle theorem is a theorem that states the measure of an inscribed angle is half of the measure of the arc it intercepts
which also means that the measure of the intercepted arc is twice the measure of the inscribed angle (this is because of how algebra works)
which means mAB=2m<ACB (inscribed angle theorem)
mAB=2*44° (substitution)
mAB=88° (algebra)
therefore, your answer is C

9A:
The problem says 35% of the 3560 applications are from boys who lived in other states.
This can be expressed as:
3560*35% = 3560*0.35 = 1246 applications.
9B:
The problem says applications to the university (3560 applications) represented 40% of all applications.
This can be expressed as:
3560 = 40% * A, where A = number of applications received in all.
To find how many applications received in all, just solve for A.
A = 3560 / 0.4 = 8900 applications.
The key to these types of problems is that "of" signals multiplication. For example, 40% of all applications is 40% * all applications.

Un paseo tiene una longitud de 1250 km. Se quiere plantar un árbol cada 0,025 km. ¿cuantos arboles se plantaran? ¿ y si se planta un arbol cada 50 m?
Answer:
-Se plantarán 50.000 arboles.
-Si se planta un árbol cada 50 m, se plantarán 25.000 arboles.
Step-by-step explanation:
Para encontrar cuántos arboles se plantarán, tienes que dividir la longitud el paseo entre la distancia que habrá entre los árboles:
1250/0,025=50.000
Ahora, para encontrar cuántos arboles se plantarán si se planta uno cada 50m, primero tienes que encontrar cuántos kilómetros hay en 50 m considerando que 1 km es igual a 1000 metros. Para esto, puedes utilizar una regla de tres:
1 km → 1000 m
x ← 50 m
x=(50*1)/1000
x= 0,05 km
Ahora puedes dividir la longitud del paseo entre 0,05 para encontrar el número de arboles que se plantarán:
1250/0.05=25.000
De acuerdo a esto, la respuesta es que se plantarán 50.000 arboles.
Si se planta un árbol cada 50 m, se plantarán 25.000 arboles.
Please help me with the question please ASAP
Answer:
The ratio of perimeter of ABCD to perimeter of WXYZ = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
First, we have to determine the multiplicative factor of the dimensions for both figures.
Considering sides AB and WX,
multiplicative factor = [tex]\frac{12}{8}[/tex]
= 1.5
So that:
XY = 6 x 1.5 = 9
YZ = 7 x 1.5 = 10.5
ZW = 7 x 1.5 = 10.5
Perimeter of ABCD = 6 + 7 + 7 + 8
= 28
Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of the two quadrilaterals can be determined as;
ratio = [tex]\frac{perimeter of ABCD}{Perirmeter of WXYZ}[/tex]
= [tex]\frac{28}{42}[/tex]
= [tex]\frac{2}{3}[/tex]
The ratio of the perimeter of ABCD to perimeter of WXYZ is [tex]\frac{2}{3}[/tex].
