A≈18.38

Step-by-step explanation:

Solve for area

Shape: Parallelogram

Formula: Base*Height

5.25*3.5=18.375

Round answer

Hope this helps.

Answer:

Step-by-step explanation:

(i) Area of ABCD = (base1+base2)*height/2

                           = (6+12)*4/2 = 36 cm2

(ii) Volume = Area of ABCD * length = 36 * 25 = 900 cm3

(iii) Total SA = Area of ABCD *2 + 25*5*2 + 6*25 + 12*25

                    = 72                         + 250      + 150   + 300

                    = 772cm2

y=32

Step-by-step explanation:

=1152/36

y=32

Answer:

D. -180

Step-by-step explanation:

Answer: 32

Step-by-step explanation:

There are 18 boys and 14 girls (4 more boys than girls.  32 students total.

If the ratio of boys to girls is 9 : 7, there are 32 students in this Year 9 group altogether.

Let's denote the number of boys as "9x" and the number of girls as "7x" since the ratio of boys to girls is 9:7. We are also given that there are 4 more boys than girls, so we can set up an equation:

Number of boys = Number of girls + 4

9x = 7x + 4

Now, we can solve for "x":

9x - 7x = 4

2x = 4

x = 2

Now that we have the value of "x," we can find the number of boys and girls:

Number of boys = 9x = 9 * 2 = 18

Number of girls = 7x = 7 * 2 = 14

Finally, to find the total number of students in the group, we add the number of boys and girls:

Total number of students = 18 (boys) + 14 (girls) = 32.

The ratio of boys to girls is 9:7, and there are 4 more boys than girls.

The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

She sold:

1/3 on Tuesday.

5/12 on Wednesday.

What fraction of blue shirts did she sell on Tuesday and Wednesday?

Sum of fractions.

The lesser common multiplier between 3 and 12, which is 12.

So

[tex]\frac{1}{3} + \frac{5}{12} = \frac{\frac{12*1}{3} + \frac{12*5}{12}}{12} = \frac{4 + 5}{12} = \frac{9}{12} = \frac{3}{4}[/tex]

The answer is 3 and 1/6 cups.

Step-by-step explanation:

If Joaquin used 1 and 3/6 cups of apple juice and 1 and 4/6 cups of orange juice for the punch, there is a total of 2 cups and the fractions can be added as their denominators are the same.

3/6 + 4/6 = 7/6 cups

So the total juice in the punch is 3 and 1/6 cups.

It is approximately 1320.25

25.12 in or 8π

Step-by-step explanation:

Since you didn't specify whether or not to leave pi or to make it be 3.14, I did both.

The formula for the circumference of a circle is...

[tex]C=2\pi r[/tex]

So...

[tex]C=2*3.14*4[/tex]

C = 25.12 in

If you want to leave pi...

[tex]C=2*\pi *4[/tex]

C = 8π

Answer:

x=14

Step-by-step explanation:

4x-y=21

y=3x-7

Substitute the second equation in for y in the first

4x - (3x-7) = 21

Distribute the minus sign

4x -3x +7 = 21

x +7 = 21

Subtract 7 from each side

x+7-7=21-7

x=14

Answer:   x=14 is right answer

4x-y=21 =

Slope = 4

x-intercept = 21/4 = 5.25000

 y-intercept = 21/-1 = -21.00000

y=3x-7 =

 Slope = 6.000/2.000 = 3.000

 x-intercept = 7/3 = 2.33333

 y-intercept = -7/1 = -7.00000

Answer:

tan ∠L = 65/72

Step-by-step explanation:

The tangent ratio is:

tan of angle x = opposite/adjacent

Looking from the perspective of angle L, find the opposite side.

This side is MN, measuring 65 units.

opposite = 65

Now let's find the adjacent side.

This side is LN, measuring 72 units.

adjacent = 72

Therefore, the tangent ratio of angle L is 65/72.
