Answer:
7.5 mph
Step-by-step explanation:
Given :
Distance traveled in miles = 10 miles
Time taken = 1 hour 20 minutes
In other to express average speed on terms of miles per hour :
Time in hour = 80 / 60 = 1.333333 hours
Average speed = Distance traveled / time taken
Distance = 10 miles / 1.33333 hours
Distance = 7.5 miles per hour

Q9) Surface Area of a cylinder
= 2πr(r + h)
Diameter = 12cm , Radius = Diameter/2 = 12 cm/2
r = radius = 6cm
h = height = 10 cm
Surface area = 2 × π × 6(6 + 10)
= 603.18579 cm²
Approximately = 603.2 cm²
Q11) Volume of a rectangular prism
Length × Width × Height
Length = 6.5cm
Width = 8.5 cm
Height = 4 cm
Volume = 6.5 cm × 8.5 cm × 4 cm
Volume = 221 cm³
Q12) Volume of the cylinder = πr²h
r = radius = 1.7m
h = height = 9 m
Volume = π × 1.7 × 9
= 81.71 m³
Approximately = 81.7 m³
Q13) Volume of the cylinder = πr²h
Diameter = 0.8m, Radius = Diameter/2 = 0.8m/2
r = radius = 0.4m
h = height = 1.5 m
Volume = π × 0.4 × 1.5
= 0.75 m²
Approximately = 0.8 m³

Answer:

Step-by-step explanation:
We know that alternate angles ( Z angles) are equal
So, the angle that is adjacent to (13x + 2) = (12x+3)
First, calculate the measure of the angle adjacent to (13x+2)
We know that the angles on a straight line add up to 180 degrees.
Therefore, the angle adjacent to (13x+2) = 180-(13x+2)
Simplify this to: 178-13x
So, now we have an equation
178 - 13x = 12x + 3
Rearrange to find the value of x
25x = 175
x = 7
Hope this helps.

Your friend earns 7x dollars for
working x hours. How much does
your friend earn for working
16 hours? 40 hours?
16 hours $
40 hours $
Answer:
$112 for 16 hours
$280 for 40 hours
Step-by-step explanation:
Well, given that if 7x dollars are earned working for x hours (x is assumed to be 1), then $7 are earned for every hour worked. So we can pretty much multiply $7 (Money earned per hour) by 16 and then 40 (Hours worked). 7*16=112, and 7*40=280. And there are your two answers.
On a field trip to the farm, students counted a combined total of 27 sheep
and cows. There are 15 more sheep than cows. If s represents the number
of sheep and c represents the number of cows, which system of equations
correctly represents this situation
Answer:
s = c + 15
s + c = 27
substitute for s:
(c + 15) + c = 27
2c = 12
c = 6
s = 21
The system of equation which correctly represents the situation is s + c = 27 and s - c = 15.
What does a System of Linear Equations define?Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.
System of linear equations involve two or more linear equations.
Given that,
Combined total of sheep and cows = 27
Number of sheep = Number of cows + 15
Let s represents the number of sheep and c represents the number of cows.
s + c = 27
s = c + 15 ⇒ s - c = 15
Hence the system of equation is s + c = 27 and s - c = 15.

☛[tex] \underline{ \underline{ \text{question}}}[/tex] : In the given figure , O is the centre of the circle. Two equal chords AB and CD intersect each other at E. Prove that :
i. AE = CE
ii. BE = DE
*Random/irrelevant answers will not be tolerated !
Answer:
See Below.
Step-by-step explanation:
In the given figure, O is the center of the circle. Two equal chords AB and CD intersect each other at E.
We want to prove that I) AE = CE and II) BE = DE
First, we will construct two triangles by constructing segments AD and CB. This is shown in Figure 1.
Recall that congruent chords have congruent arcs. Since chords AB ≅ CD, their respective arcs are also congruent:
[tex]\stackrel{\frown}{AB }\, \cong\, \stackrel{\frown}{CD}[/tex]
Arc AB is the sum of Arcs AD and DB:
[tex]\stackrel{\frown}{AB}=\stackrel{\frown}{AD}+\stackrel{\frown}{DB}[/tex]
Likewise, Arc CD is the sum of Arcs CB and DB. So:
[tex]\stackrel{\frown}{CD}=\stackrel{\frown}{CB}+\stackrel{\frown}{DB}[/tex]
Since Arc AB ≅ Arc CD:
[tex]\stackrel{\frown}{AD}+\stackrel{\frown}{DB}=\stackrel{\frown}{CB}+\stackrel{\frown}{DB}[/tex]
Solve:
[tex]\stackrel{\frown}{AD}\, \cong\,\stackrel{\frown}{CB}[/tex]
The converse tells us that congruent arcs have congruent chords. Thus:
[tex]AD\cong CB[/tex]
Note that both ∠ADC and ∠CBA intercept the same arc Arc AC. Therefore:
[tex]\angle ADC\cong \angle CBA[/tex]
Additionally:
[tex]\angle AED\cong \angle CEB[/tex]
Since they are vertical angles.
Thus:
[tex]\Delta AED\cong \Delta CEB[/tex]
By AAS.
Then by CPCTC:
[tex]AE\cong CE\text{ and } BE\cong DE[/tex]

Lila covered 55 ft squared of her back yard with 3/4 of a load of sod. She has 3 loads of sod in all. If she wants to cover all 250 ft squared of her yard, does she have enough sod?
Answer:
More sod is needed
Step-by-step explanation:
Well we know that 3/4 of a bag of sod covers 55 ft^2 then if we divide 55 by 3 we get 18.3333 we take that and multiply by 4 to get 73.333 or the amount one bag of sod can cover
73.333*3 cuz 3 bags of sod is 220 ft^2
She needs more sod

En una librería se venden novelas a 16 euros y guías de viaje a 10 euros. Si hoy se han vendido 37 libros en total con una recaudación de 508 euros, calcula el número de ejemplares vendidos de cada tipo.
Answer:
En la librería se vendieron 23 novelas y 14 guías de viaje.
Step-by-step explanation:
Con la información proporcionada puedes plantear las siguientes ecuaciones:
x+y=37 (1)
16x+10y=508 (2), donde:
x es el número de novelas vendidas
y es el número de guías de viaje vendidas
Primero, puedes despejar x en (1):
x=37-y (3)
Ahora, debes reemplazar (3) en (2) y despejar y:
16(37-y)+10y=508
592-16y+10y=508
592-508=16y-10y
84=6y
y=84/6
y=14
Después, debes reemplazar el valor de y en (3) para encontrar el valor de x:
x=37-14
x=23
De acuerdo a esto, la respuesta es que en la librería se vendieron 23 novelas y 14 guías de viaje.

Answer:
v = 120
Step-by-step explanation:
The right angle is egual to 180-39-v, so it is: v-141
U now that the sum of the internal angles of a triangle is 180°.
180 = (v-48)+(v)+(v-141)
180 = 3v - 180
3v = 360
v = 360/3

Raymond used 36 cubes to build the first layer of a rectangular prism. The edge length of each cube was 1 inch. The finished prism had a total of 8 layers. What is the volume of Raymond's prism in cubic inches?
Answer:
[tex]Volume = 288in^3[/tex]
Step-by-step explanation:
Given
[tex]Base\ Cubes = 36[/tex]
[tex]Layers = 8[/tex]
Required
The volume of the prism
The number of base cubes represents the base area and the number of layers represents the height of the prism.
So, the volume is calculated as:
[tex]Volume = Base\ Cubes * Layers[/tex] i.e Base Area * Heights
[tex]Volume = 36 * 8[/tex]
[tex]Volume = 36in^2 * 8in[/tex]
