Answer:

Hello! answer: a = 8

Step-by-step explanation:

2.4 × 8 = 19.2

19.2 + 8 = 27.2 therefore a = 8 hope that helps!

Answer:

a = 8

Step-by-step explanation:

2.4a + 8 = 27.2

2.4a + 8 - 8 = 27.2 - 8

2.4a = 19.2

2.4a ÷ 2.4 = 19.2 ÷ 2.4

a = 8

Answer:

Mark:

x + y + z = 10

Jessica:

5x + 2y + 3z = 28

Nate:

3x + 3y + z = 20

Step-by-step explanation:

Let

x = number of pop song downloaded by Mike

y = number of rock song downloaded by Mike

z = number of hip song downloaded by Mike

Mark downloaded 10 songs in total consisting of pop, rock, and hip hop

Mark:

x + y + z = 10

Jessica downloaded five times as many pop songs, twice as many rock schgs, and three times as many hip hop songs as Mark. She downloaded 28 songs total.

Jessica:

5x + 2y + 3z = 28

Nate downloaded 20 songs total with three times as many pop songs, three times as many rock songs, and the same number of hip hop songs as Mark.

Answer:

17 hours

Step-by-step explanation:

From the above question,

Anthony is practicing 4 days in a week

Hence

The number of hours he practices in the morning for 4 days =

1.75 hours × 4

= 7 hours

The number of hours he practices in the evening for 4 days =

2.5 hours × 4

= 10 hours

Therefore, the total number of hours he practices this week

= 7 hours + 10 hours

= 17 hours

Answer:

The Second Picture

Step-by-step explanation:

Answer:

The parallel sides are called the bases of the trapezoid

Step-by-step explanation:

[tex]area = (\frac{a + b}{2}) \times h[/tex]

       [tex]= \frac{14.1+22.7}{2} \times 18\\\\=331.2 \ unit^2[/tex]

Answer:

331.2 units^2

Step-by-step explanation:

There is a formula for the area of a trapezoid of legs a and b and width h:

a + b

----------- * h

     2

Here the leg lengths (which are parallel) are 14.1 and 22.7, and the width is 18.  Thus, the desired area is

14.1 + 22.7                        36.8

---------------- * 18  =  A  = ------------ * 18 = 331.2 units^2

       2                                   2

The dimension 20.3 is not needed here.

Answer:

2700 I think?

Step-by-step explanation:

Um 3/ 1/4 = 12 and 3 3/4 / 1/4 = 15 so 15 * 12 * 15 is 2700

Answer:

x = ± 10

Step-by-step explanation:

Given

y = x² - 100 ← a difference of squares , that is

y = x² - 10² = (x - 10)(x + 10)

To find the x- intercepts let y = 0 , that is

(x - 10)(x + 10) = 0

Equate each factor to zero and solve for x

x - 10 = 0 ⇒ x = 10

x + 10 = 0 ⇒ x = - 10

Answer:

Died speciman prior would be best to measure the bird’s mass.The length (also bill-to-tail length) of a bird is usually measured from dead specimens prior to their being skinned for preservation. The measurement is made by laying the bird on its back and flattening out the head and neck gently and measuring between the tip of the bill and the tip of the tail.

Answer:

the value of the car after one year is 28400

Answer:

d=13

Step-by-step explanation:

D = √(x2 - x1)2 + (y2 - y1)2

D = √(-6 - (-8))2 + (1 - 4)2

D = √(-6 + 8)2 + (-3)2

D = √(2)2 + (-3)2

D = √4 + 9

D = √13

Answer:

(0, 4)

(1, 5)

(-1, 3)

Step-by-step explanation:

the function is already in slope-intercept form (y=mx+b). B is the y intercept and mx is the slope. The equation y=x+4 means that there is a y intercept of 4 and a slope of 1. So, y intercept is when x is equal to 0 which means one of your points will be (0,4). The next point will be 1 unit up and 1 unit to the right of the point (0, 4) and the third point will be 1 unit down and 1 unit to the left of (0, 4). This gives you the points (1, 5) and (-1, 3)

Answer:

2.05 cm

Step-by-step explanation:

3.14× (n+3)²×10 = 800

31.4(n+3)²=800

(n+3)²= 800/31.4

(n+3)²= 25.48

n+3 =√25.48

n+3= 5.05

n = 5.05 -3 = 2.05

so, the radius should be increased :

2.05 cm

Answer:

0.36

Step-by-step explanation:

Answer:

Step-by-step explanation:

take 60 degree as reference angle

using cos rule

cos 60=adjacent/hypotenuse

1/2=80/x(do cross multiplication)

80*2=x

160=x

Answer:

x = 160

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{CD}{CE}[/tex] = [tex]\frac{80}{x}[/tex] ( multiply both sides by x )

x × cos60° = 80 ( divide both sides by cos60° )

x = [tex]\frac{80}{cos60}[/tex] = 160

the 1 is in the 10 million place

Answer:

( [tex]\frac{1}{2}[/tex], 0 )

Step-by-step explanation:

To find the x- intercepts let y = 0, that is

2x² + 3x - 2 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 2 = - 4 and sum = + 3

The factors are + 4 and - 1

Use these factors to split the x- term

2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )

2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term

(x + 2)(2x - 1) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

The x- intercepts are (- 2, 0 ), ( [tex]\frac{1}{2}[/tex], 0 )

Complete question:

If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of the third sides? A.20cm B.16cm C.22cm D.23cm

Answer:

B. 16 cm

Step-by-step explanation:

Given;

two lengths of the triangle as 15 cm and 4 cm

The length of the third side of the triangle must be less than the sum of the two given sides.

Length of third side < 15 cm + 4 cm

Length of third side < 19 cm

The only option less than 19 cm is B. 16 cm

Therefore, the correct option is B. 16 cm
