A sum of money is shared in the ratio 3:7.
If the smaller share is $450, what is the
8
larger share?
(A) $315
(B) $1050
$1500
(D)
$3150
| (C)

Answers

Answer 1
B) = $1050.

So we are given the ratio 3:7. If we want to share $450 in the smaller share, which would be the 3, we’d need to work out what $450/3 is… so then we can multiply the answer by the 7 to work out the larger share. $450/3 = $150. So then we do $150 x 7 = $1050.
So $1050 is the larger share.
Answer 2

Answer:

B) $1050

Step-by-step explanation:

[tex]450(7/3)=(450)(7)/3=3150/3=1050[/tex]

1. Diameter of a semicircles =14cm

Radius or semicircle =7cm

*Area if circle =pi radius 2

=22/7 × 7×7cm 2

=154cm 2

But semicircle is half if a circle so,

Area of a semicircle =1/2 ×154cm2

2. Radius of the circle =1cm

Area of the circle=pi radius 2

=3.14×1×1

first off, let's get the equation of each line, now, let's notice they're lines, thus we can just use two points from each and the point-slope form to get it, so let's do so, Check the picture below.

[tex]\begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{-2}(x-\stackrel{x_1}{(-3)})\\\\\\y=-2(x+3)\implies \blacktriangleright y = -2x-6 \blacktriangleleft\\\\[-0.35em]\rule{34em}{0.25pt}[/tex]

now, if we look at the first line, it has a hole when x = -1, however is going upwards to the left otherwise, so we can say the equation includes values to the left of x = -1.

the second equation has a hole when x = 2, so we can say that the equation includes values from x = +2 onwards.

Answers

The surface area of the triangular prism ramp is: 1,020 ft².

Surface Area of Triangular Prism

Surface area = 1/2(base area × height)

The triangular prism has the following dimensions:

base area = 20 × 12 = 240 ft²

height = 8.5 ft

Plug the values into the formula:

Surface area = 1/2(240 × 8.5)

Surface area = 1/2(2,040)

Surface area = 1,020 ft²

Therefore, the surface area of the triangular prism ramp is: 1,020 ft².

A. $45
B. $40
Ο Ο Ο Ο
C. $60
D. $55

please help

Answers

Answer:

B. 40

Step-by-step explanation:

if x=300, it means x>200, then b(x)=0.1(x-200)+30; ⇔ b(x)=0.1*100+30= 40 [USD].

The bill for a person who uses 300 kWh in a month is $40.

Option B is the correct answer.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

For a person who uses 300 kWh in a month, we need to use the second part of the function:

b(x) = 0.10(x - 200) + 30, x > 200

Substituting x = 300, we get:

b(300) = 0.10(300 - 200) + 30

b(300) = 0.10(100) + 30

b(300) = 10 + 30

b(300) = 40

Therefore,

The bill for a person who uses 300 kWh in a month is $40.

Which of the following is a linear function?

one over three x = y − 3
y = x3 + 2
y = 6x2
y = two over three x

Answers

Answer:

[tex]\bold{y = 3x + 2}[/tex]

Step-by-step explanation:

In a linear equation, [tex]y=mx+b[/tex], the "[tex]m[/tex]" is identified as the slope, while the b is where you begin, the coefficient: y-intercept.

Now, with that said, let us look at each option, and see which one matches the linear equation.

Option 1

One over three x = y - 3

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

As you can see, the [tex]y[/tex] should be in front of the equation. And the [tex]-3[/tex] should be next to [tex]x[/tex].

Option 2

[tex]y = 3x + 2[/tex]

This equation is a  linear equation: the [tex]y[/tex] is in the right place, the coefficient is right next to [tex]x[/tex], and where you begin is at the right place. If you look at this equation, and the linear equation, you will notice they both match.

Option 3

[tex]y = 6\times2[/tex]

The equation does not make sense in terms of linear equations, first off all. There is nothing to show it is a linear equation, except from the [tex]y[/tex]. It is the same thing as just adding two numbers and putting an equal sign and [tex]y[/tex] in front of it, which is not a linear equation.

Option 4

y = two over three x

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

There is no coefficient in this equation, therefore, it is not a linear equation.

When this is expanded, it becomes ...

  x^2 -(p+q)x +pq = 0

That is, the opposite of the x-coefficient is the sum of the solutions.
