5 x 6 = 30

6 x 6 = 36

8 x 6 = 48

Answer:

8

Step-by-step explanation:

The answer is 8 because the scale factor is 6 so if you divide the side that is corresponding to x (in this case 48) you would divide it by 6 because 6 is the scale factor. Hopefully I make sense...

Answer:

$300

Step-by-step explanation:

5% of x + 5 kg = 20

0.05 * x + 5 = 20

0.05x + 5 = 20

0.05x = 20 - 5

0.05x = 15

x = 15 / 0.05

x = $300

Answer:

Braylen has 15 apps on his phone

Step-by-step explanation:

Carli has 3 times the amount of apps that Theiss does

So we divided 90 by 3

90 ÷ 3 = 30

Now we divide 30 by 2 to find out how many apps Braylen has, since he has half the amount of apps that Theiss does

30 ÷ 2 = 15

So Braylen has 15 apps

Incomplete question. The remaining question read;

What percentage of meals had less than 10 grams of fat?  Round your answer to the nearest tenth of a percent.

Answer:

21.7%

Step-by-step explanation:

Remember, we are told that 98 out of the 450 meals served at 75 cafeterias had less than 10 grams of fat.

To calculate the percentage, we divide 98 by 450 and then multiply by 100:

[tex]\frac{98}{450}*100=[/tex] 21.7% approximately to the nearest tenth of a percent.

Answer:

The length of the chord is 16 cm

Step-by-step explanation:

Mathematically, a line from the center of the circle to a chord divides the chord into 2 equal portions

From the first part of the question, we can get the radius of the circle

The radius form the hypotenuse, the two-portions of the chord (12/2 = 6 cm) and the distance from the center to the chord forms the other side of the triangle

Thus, by Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides

Thus,

r^2 = 8^2 + 6^2

r^2= 64 + 36

r^2 = 100

r = 10 cm

Now, we want to get a chord length which is 6 cm away from the circle center

let the half-portion that forms the right triangle be c

Using Pythagoras’ theorem;

10^2 = 6^2 + c^2

c^2 = 100-36

c^2 = 64

c = 8

The full

length of the chord is 2 * 8 = 16 cm

Answer:

29.79 should be the answer

Step-by-step explanation:

200 copies 19.50 + 9.00 for 100 copies = 28.50 + 4% = 29.79

The cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2 and  =$29.78 is the cost of 300 copies including a sales tax of 4 1/2

Two or more expressions with an Equal sign is called as Equation.

Given,

Dakota Printing charges 19.50$ for the first 200 copies and 9$ for every 100 additional copies.

Let r be the  number of sets of 100 resumes.

c(r)=$19.5 when r represent an integer and is less than 2

c(r)=$19.5+(r-2) ($9) (1+0.045)

c(r)=$19.5+(r-2) ($9) (1.045) when r represent an integer and is greater than 2

the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2

c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2

Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)

=$28.5+$28.5(0.045)

=$28.50+$1.28

=$29.78

Hence, the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2 and  =$29.78 is the cost of 300 copies including a sales tax of 4 1/2

x = 4

Step-by-step explanation:

The smaller triangle is an equilateral triangle, so all sides and angles are the same. We know that one side is labeled as 5, so all sides of that little triangle are 5.

The bigger triangle is an isosceles triangle because those two angles are marked as congruent. So, line JM and line KM are congruent as well.

The little triangle and the big triangle share side KM, so KM is equal to 5.

If JM is equal to KM and KM is equal to 5, JM is also five. That means:

x + 1 = 5

Subtract 1 from each side.

x = 4

And there we go.

Answer:

The car must drive at 108 km/h to cover the same journey.

Step-by-step explanation:

Given that:

Time taken by bus journey = 45 minutes = [tex]\frac{45}{60} = 0.75\ hour[/tex]

Speed of bus = 60 km/h

Distance of the journey = Speed * Time

Distance of the journey = 60 * 0.75 = 45 km

The car needs to cover 45 km in 25 minutes.

25 minutes = [tex]\frac{25}{60}\ hour[/tex]

Distance = Speed * Time

45 = [tex]\frac{25}{60}*Speed[/tex]

Speed = [tex]45*\frac{60}{25}[/tex]

Speed = 108 km/h

Hence,

The car must drive at 108 km/h to cover the same journey.

The area of the real object that the scale drawing models will be 300 square cm. Thus, the correct answer is option (A).

Given:

For Object
Scale factor: 1:5

For Scale drawing

Area = 12 square cm

The scale factor of 1:5 means that every unit on the scale drawing represents 5 units in the real object.

Since area is a two-dimensional measurement, the scale factor for area will be the square of the linear scale factor.

Here, the linear scale factor is 1:5, which means that each unit on the scale drawing represents 5 units in the real object.

Therefore, the area scale factor will be (1:5)² = 1:25.

If the area of the scale drawing is 12 square cm, then the area of the real object that the scale drawing models will be 12 × 25 = 300 square cm.

Therefore, the correct answer is:

A. 300 square cm.

Answer:

x = 4

Perimeter is the length around the rectangle (or any other shape). For rectangles, it's found by adding the side lengths. In this case, it required algebra to solve for x.

Answer:

x = 4

Step-by-step explanation:

The opposite sides of a rectangle are congruent.

The perimeter is the sum of the 4 sides, thus

2(5x) + 2(x - 3) = 42 ← distribute parenthesis and simplify left side

10x + 2x - 6 = 42

12x - 6 = 42 ( add 6 to both sides )

12x = 48 ( divide both sides by 12 )

x = 4
