Step-by-step explanation:

Dividing by a fraction is the same as multiplying by the reciprical of the fraction, i.e. dividing by 1/4 is the same as multiplying by 4/1 :)

Answer:

  18, 21

Step-by-step explanation:

Let x represent the smaller number. Then x+3 is the larger number, and the other relation between them is ...

  3(x+3) = (7/10)(5x)

  6x +18 = 7x . . . . . multiply by 2 and simplify

  18 = x . . . . . . . . . . subtract 6x

The two numbers are 18 and 21.

Answer:

250 in²

Step-by-step explanation:

There are four identical rectangles so therefore area of one rectangle times 4. Then add the sum of the areas of the two identical squares.

4( l x b) + 2( l x b)

4( 10 x 5) + 2(5 x 5)

4(50) + 2(25)

200 + 50

Therefore 250 in²

Answer:

it's answer is B

Step-by-step explanation:

f (x)=x (x-2)+3 (x-2)

=x2+x-6

Let's take the first value of x and y.

When x = 4, y = -3. This also gives us point

(4, -3). We need another point to find the slope.

From the table I see the point (5, -4.5)

.

See it?

Let m = slope

m = (-4.5 -(-3))/(5-4)

m = (-4.5 + 3)/1

m = (-1.5)/1

m = -1.5

Now, use the slope m and one of the points to plug into the point-slope formula.

Here is the point-slope formula:

y - y_1 = m(x - x_1)

I will use the point (4, -3) and m.

y - (-3) = -1.5(x - 4)

y + 3 = -1.5x + 6

The slope-intercept form we want is

y = mx + b.

y = -1.5x + 3

Answer:

1.a=5cm

Surface area :6a²=6×5²=150cm²

2.r=3cm

h=5cm

total surface area of cylinder =2πr(r+h)

=2π×3(3+5)=48π cm²

3.

l=4m

b=5m

h=2m

now.surface area =2(lb+lh+bh)

=2(4*5+4*2+5*2)

=76m²

4.

r=6cm

surface area =4πr²=4*π*6²=144πcm²

5.

slant height (S)=8cm

length =breadth=(L)=4cm

Surface area of pyramid =area of base + 2* area of trainglular face

=L²+2*S*L

=4²+2*8*4

=80cm²

Answer:

0

Step-by-step explanation:

given the system of equations, what is the value of the system to determinant.

x + y = 8

x + y = 10

This can be written in the form AX = b

A is a 2 by 2 matrices

b is a column matrix

Taking the determinant of A

[tex]A =\left[\begin{array}{ccc}1&1\\1&1\\\end{array}\right][/tex]

We are to finds the determinant

|A| = 1(1) - 1(1)

|A| = 1 -1

|A| = 0

hence the required determinant is 0

Answer:

x = 33

Step-by-step explanation:

these two angles are a linear pair, they form a straight line

there are 180 degrees in a straight line

so you can add each expression and have sum equal 180

2x-18 + 4x = 180

6x - 18 = 180

6x = 198

x = 33

Answer:

a = x² + 3x - 40

Step-by-step explanation:

a = l * w

a = (x - 5)(x + 8)

a = x(x + 8) - 5(x + 8)

a = (x² + 8x) + (- 5x - 40)

a = x² + 3x - 40

Answer:

Step-by-step explanation:

This is a right triangle

the 20 foot ladder is the hypotenuse

The 9 foot at the bottom is one leg

The height is the remaining leg

Use the pythagorean theorem

a² + b² = c²

a² + 9² = 20²

Subtract 9² from both sides

a² = 20² - 9²

a² = 400 - 81

a² = 319

Take the square root of both sides

a = 17.860571099491752

rounded

17.9 feet

Answer:

A ladder is the hypotenuse of the right triangle.

Missing leg is x.

Use Pythagorean:

Given:

Two sides of a triangle are 14 and 23.

To find:

The angle for the measures for the third side of a triangle.

Solution:

If a, b, c are three sides of a triangle, then

[tex]a+b>c[/tex]

[tex]a+c>b[/tex]

[tex]b+c>a[/tex]

It is given that two sides of a triangle are 14 and 23.

Let the third side of the given triangle be c. Then, using the above inequalities, we get

[tex]a+b>c[/tex]

[tex]14+23>c[/tex]

[tex]37>c[/tex]                 ...(i)

Similarly,

[tex]a+c>b[/tex]

[tex]14+c>23[/tex]

[tex]c>23-14[/tex]

[tex]c>9[/tex]                 ...(ii)

And,

[tex]b+c>a[/tex]

[tex]23+c>14[/tex]

[tex]c>14-23[/tex]

[tex]c>-9[/tex]                 ...(iii)

Using (i), (ii) and (iii), we get

[tex]9<c<37[/tex]

Therefore, the range for third side of the triangle is [tex]9<c<37[/tex].

Answer:

The perimeter, in inches, is 32.

Step-by-step explanation:

Since this shape is a square, we know that all sides are equal.

The information given to us is that one side of the square measures 8 inches.

8 + 8 + 8 + 8 = 32

Answer:

c   32

Step-by-step explanation:

Squares have 4 sides of the same length

8 * 4 = 32

Answer:

She purchased the item at a price of Rs 1,406.

Step-by-step explanation:

5% of discount:

This means that she paid 100% - 5% = 95% = 0.95 of the original price of x, that is, 0.95x, and 0.05x was the discount.

Original price:

She got the discount amount of Rs 74.

74 is 5% of the original price, that is:

[tex]0.05x = 74[/tex]

[tex]x = \frac{74}{0.05}[/tex]

[tex]x = 1480[/tex]

What price she purchased:

74 subtracted from the original price, that is, x - 74. So 1480 - 74 = 1406.

She purchased the item at a price of Rs 1,406.

Answer:

H0 : u ≤ 40 mins  against  Ha: u> 40 mins

Step-by-step explanation:

The hypotheses will be set as follows

H0 : u ≤ 40 mins  against  Ha: u> 40 mins

The null hypothesis is that the mean delivery time is less and equal to 40 minutes.

against the claim

that the mean delivery time is greater than 40 minutes.

40 minutes is taken because the success depends on the factor that if the delivery time is less and equal to 40 minutes then the home delivery service will be successful

But if it is greater than 40 minutes then the home delivery service will not be successful

Answer:

a=1, b=3

Step-by-step explanation:

2a+3b=11---(1)

4a-5b=-11---(2)

(1)×2-(2): 4a+6b=22

-) 4a-5b=-11

------------------

11b=33

b=3

Put b=3 into (1), we have

2a+3(3)=11

2a=2

a=1

Answer:

Did you want the length of the diagonal line?

-----------------------------------

d² = 64² + 100²

d² = 4,096 + 10,000

d² = 14,096

Take the square root of both sides

d = 118.7265766372

Rounded
