1 feet = 12 inches

4 feet = 48 inches

Why?

4 x 12 = 48

Answer:

102 mph

Step-by-step explanation:

Eliana travels at an average speed of 50 mph for 60 miles.

Without stopping, Eliana then travels 130 miles in 2.5 hours.

We calculate the speed here

Speed = Distance in miles /Time in hours

Speed = 130 miles/2.5 hours

= 52 miles per hour

Hence, her average speed for the entire journey is calculated as:

50 mph + 52 mph

= 102 mph

Answer:

x = 50°

Step-by-step explanation:

x + 20° + 30° = 180°

x = 180° - 20° - 30°

x = 130°                   (This one is other x)

x + 130° = 180°

x = 180° - 130°

x = 50°

Answer:

(B) M - J = 6

Step-by-step explanation:

Here we have the variables:

M = number of games that Mike won.

J = number of games that Jeanie won.

And we know that there is a total of 38 games played, then if a game can not end in a draw, we have the equation:

M + J = 38

Now we want to find the other equation needed to solve this problem:

We also know that Mike won 6 more games than Jeanie, this is written as:

M = J + 6

We can subtract J in both sides to get:

M - J = 6

This is the equation from option B, so we can conclude that the correct option is B.

Answer: 12.2 km/h

Answer:

There are 8 granola bars in a pack and 12 fruit rolls in a pack.

Step-by-step explanation:

10x+6y=152

5x+3y=76

7x+12y=200

-20x-12y=-304

-13x=-104

x=8

40+3y=76

3y=36

y=12

Answer:

B

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{?}{6}[/tex] = [tex]\frac{18}{12}[/tex] ( cross- multiply )

12 ? = 108 ( divide both sides by 12 )

? = 9 → B

Answer:

h > 2                   or  h < 1

Step-by-step explanation:

|2h-3| >1

Solve 2 inequalities

2h-3 > 1  or 2h-3 < -1  (remembering to flip the inequality for the negative solution)

2h-3 > 1      or 2h-3 < -1

Add 3 to each side

2h-3+3 > 1+3  or 2h-3+3 < -1+3

2h>4              or    2h < 2

Divide by 2

2h/2>4/2              or    2h/2 < 2/2

h > 2                   or  h < 1

Answer:

40m

Step-by-step explanation:

if 20 it the diameter then the daius is 10 which is multiplied by 4

Answer:

100pi m or approximately 314 m^2

Step-by-step explanation:

We need to find the radius to find the area

r = d/2 = 20/2 = 10

The area of a circle is

A = pi r^2

A = pi (10)^2

A = 100 pi  m^2

If we approximate pi by 3.14

A = 100*3.14

A = 314 m^2

Answer:

Both of your answers are correct

Step-by-step explanation:

Answer:

d

e

Step-by-step explanation:

2x ≤ 5x - 15

step 1 subtract 5x from each side

2x - 5x = -3x

5x - 5x cancels out

we now have -3x ≤ -15

step 2 divide each side by -3

-3x / -3 = x

-15 / -3 = 5

IMPORTANT NOTE ( when you divide by a negative number you must flip the sign )

We would be left with x ≥ 5

now let's Plug in 10

2(10) ≤ 5(10) - 15

2(10) = 20

20 ≤ 5(10) - 15

5(10) = 50

20 ≤ 50 - 15

50 - 15 = 35

20 ≤ 35 ✓

Given:

The figure of two triangle XYZ and UWV.

To find:

The theorem that is used to verify [tex]\Delta XYZ\sim \Delta UWV[/tex].

Solution:

In triangle XYZ,

[tex]m\angle X+m\angle Y+m\angle Z=180^\circ[/tex]        (Angle sum property)

[tex]70^\circ+90^\circ+m\angle Z=180^\circ[/tex]

[tex]160^\circ+m\angle Z=180^\circ[/tex]

[tex]m\angle Z=180^\circ-160^\circ[/tex]

[tex]m\angle Z=20^\circ[/tex]

In triangle XYZ and triangle UWV,

[tex]m\angle Y\cong m\angle W[/tex]                  (Right angles)

[tex]m\angle Z\cong m\angle V[/tex]                  (Equal measures)

Two angles of one triangle are congruent to corresponding angles of another triangle. So, the triangles are similar by AA property of similarity.

[tex]\Delta XYZ\sim \Delta UWV[/tex]           (AA similarity theorem)

Therefore, the correct option is B.

Hope this helped! Please give brainliest to let me know <3

Step-by-step explanation:

Presale tickets (p) are each worth $7: represented in the equation as 7p.

Door tickets (d) are each worth $10: represented in the equation as 10d.

They sold 345 tickets, so p+d=345. They collected $2550, so 7p+10d=2550.

Final answer:

(3) [tex]\left \{ {{7p+10d=2550} \atop {p+d=345}} \right.[/tex]

Given:

Volume of sphere = 1200 cm³

The sphere is dilated by a factor of [tex]\dfrac{3}{5}[/tex].

To find:

The volume of the dilated image.

Solution:

If two figures are similar then their volumes are proportional to cube of their corresponding sides.

We know that all sphere are similar to each other.

The sphere is dilated by a factor of [tex]\dfrac{3}{5}[/tex]. It means the ratio of new figure to original figure is

Let [tex]V_1[/tex] be the volume of original figure and [tex]V_2[/tex] be the volume of dilated figure.

[tex]\dfrac{V_2}{V_1}=\left(k\right)^3[/tex]

Where, k is the scale factor.

[tex]\dfrac{V_2}{1200}=\left(\dfrac{3}{5}\right)^3[/tex]

[tex]\dfrac{V_2}{1200}=\dfrac{27}{125}[/tex]

Multiply both sides by 1200.

[tex]V_2=\dfrac{27}{125}\times 1200[/tex]

[tex]V_2=259.2[/tex]

[tex]V_2\approx 259[/tex]

Therefore, the volume of the dilated image is 259 cubic centimetres.

Answer:

No

Step-by-step explanation:

In order to form a right triangle, you would need one of the angles to be 90 degrees. Plus all the angles don't equal 180 degrees (the angles of a triangle should add up to 180)

Answer:

64º and 116º

Step-by-step explanation:

x  + (x - 52) = 1080

2x - 52 = 180

2x = 232

x = 116º

x - 52 = 64º

Answer:

V(9, -2)

Step-by-step explanation:

U (3,8); M(6,3); V(?,?)

To go from point U to point M we went down 8-3=5 units, and to the right from 3 to 6 so 6-3=3 units. Here we got half way of the line UV so continue 5 units down and 3units right to get to V(9, -2)

U (3, 8); M(3+3= 6, 8-5= 3); V(6+3 =9, 3-5= -2)

there are 18 dogs

Answer:

14

Step-by-step explanation:

So the ratio of dogs (2) to cats (5) is 2:5

How did we go from 5 to 35?

Multiply by 7

So multiply 2 with 7 which is 14

So there are 14 dogs
