Step-by-step explanation:

velocity = distance/time taken

distance=velocity ×time taken

distance=80×4

distance=320kilometers

Answer:

The answer is C.

Step-by-step explanation:

to find the area you need to multiply the width times length, to find the length you need to add the c and 15 and have that mulitplied by 1/5

.

1/5(c+15)

Answer:

The width of the new phone will be of 4.37 inches.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

In this question:

Length was of 2.2 inches, after the modification is of 2.09 inches.

Width was of 4.6 inches, after the modification is x. So

2.2 - 2.09

4.6 - x

Applying cross multiplication:

[tex]2.2x = 2.09*4.6[/tex]

[tex]x = \frac{2.09*4.6}{2.2}[/tex]

[tex]x = 4.37[/tex]

The width of the new phone will be of 4.37 inches.

Answer:

[tex]y = \frac{1}{2} x - 3[/tex]

Step-by-step explanation:

The equation of a line can be written in the form of y=mx +c, where m is the gradient and c is the y-intercept.

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

Using the gradient formula above,

gradient of line

[tex] = \frac{ - 1 - ( - 7)}{4 - ( - 8)} [/tex]

[tex] = \frac{ - 1 + 7}{4 + 8} [/tex]

[tex] = \frac{6}{12} [/tex]

[tex] = \frac{1}{2} [/tex]

Substitute m= ½ into the equation:

y= ½x +c

To find the value of c, substitute a pair of coordinates.

When x= 4, y= -1,

[tex] - 1 = \frac{1}{2} (4) + c[/tex]

-1= 2 +c

c= -1 -2 (-2 on both sides)

c= -3

∴ The equation of the line is y= ½x -3.

Answer:

  $1.74

Step-by-step explanation:

The ratio of the increase to this year's wage is ...

  12%/112% = x/$16.24

Multiplying by $16.24, we have ...

  x = $16.24(12/112) = $1.74

The dollar amount of the wage increase is $1.74.

Answer:  a = 2.8

Step-by-step explanation:

3/4 (8a + 12) = 25.8

(3/4 * 8a) + (3/4 * 12) = 25.8

6a + 9 = 25.8

6a = 16.8

a = 2.8

Hope this helped! :)

Answer:

3/4 (8a + 12) = 25.8

(3/4 × 8a) + (3/4 × 12) = 25.8

a = 2.8

It is:

B.Divide the area of the triangle by the base and multiply the result by 2.

Answer:

H0 : μ = 18000

H1 : μ < 18000 - - - > Claim

Test value = - 3.578

Critical value = ±2.58

There is significant evidence to accept the claim that mean debt at graduation is less than $18000

Step-by-step explanation:

H0 : μ = 18000

H1 : μ < 18000

From the data:

Sample size, n = 30

Sample mean, x = 16298.37

The test statistic :

(16298.37 - 18000) ÷ (2605/sqrt(30))

−1701.63 / 475.60575

= - 3.578

The critical value :

Using the standard normal table;

Critical value at α = 0.01

Critical value = ±2.58

Decison region :

|test statistic | > |Critical value | ; reject H0

|3.578| > |2.58| ; We reject H0 and conclude that Mean debt at graduation is less than $18000

Answer:

Step-by-step explanation:

3. A single sticky note is a three-dimensional object. Meaning it has a length, width and height. Therefore, it is taking up space, and anything that takes up space has a volume. If the sticky not did not have a volume then it would not be a three-dimensional object.

4. Yes, if we knew the volume of a single sticky note, then we would simply have to multiply the volume of that individual note by the total number of sticky notes in the pile. This would give us the volume of the entire pile.

Answer: 20.83

Step-by-step explanation:  44 - 11 2/3 - 11 1/2 = 20.83

Too Easy.

Answer:

The answer is 15 ounces

Step-by-step explanation:

33/4 ÷ 4 pounds.

(4 × 3 + 3)/4 ÷ 4 pounds.

15/4 ÷ 4 pounds.

15/4 × 1/4 pounds.

15/16 pounds.

Now we know that, 1 pound = 16 ounces.

So, 15/16 pounds = 15/16 × 16 ounces = 15 ounces.

Thus, The answer is 15 ounces

[tex]_____ x 14.32 = 554.76[/tex]

Let's take '____' as x

[tex]x \times 14.32 = 554.76 \\ x = \frac{554.76}{14.32} \\ x = \frac{554.76 \times 100}{14.32 \times 100} \\ x = \frac{55476}{1432} \\ x = 38.74[/tex]

⎆ The answer of ____ x 14.32 = 554.76 in 2 decimal places will be ⇻38.74

NOTE:

We multiplied the fraction × 100 to remove the decimal points so that it'll be easier to calculate.
