Roadsign cast of shadow that is 4 feet tall at the same time a 6 foot man standing next to the sign cast a shadow of those 2.4 feet long right and solve a proportion to find how tall the sign is

Answer:

$4

Step-by-step explanation:

The equation for direct proportionality =

y = bx

where y = dependent variable

b = constant

x = independent variable

There is positive proportionality is two variables are positively related to each other.

In this question, price of lunches is the dependent variable while number of lunches is the independent variable

$16 = b4

Divide both sides by 4 to find b

b = $4

Answer:

48 stuff animals 24 myster boxes

Step-by-step explanation:

this is because the stuff animals have a greater than half the amount of getting. So you would then to 74/3. this is because if we split the total into thirds, we know that the stuff animals will have more than half. which will equal to 2/3. so will divide 74/3 we will 24, but since the stuff animals is 2/3 more likely, add or multiple 24 by 2 or add 24 again. giving us 48. then the remaining amount left of 74 will be left for the mystery boxers.

giving use the ration of 48:24

Hey there!

4x^2 - 121 + 5 = 0

COMBINE your LIKE TERMS

(4x^2) (-121 + 5) = (0)

(-121 + 5) = -116

New equation: 4x^2 - 116 = 0

ADD 116 to BOTH SIDES

4x^2 - 116 + 116 = 0 + 116

Cancel out: -116 + 116 because that gives you 0

Keep: 0 + 116 because that helps you solve for x

0 + 116 = 116

New equation: 4x^2 = 116

DIVIDE 4 to both sides

4x^2/4 = 116/4

Cancel out: 4/4 because that gives you 1

Keep: 116/4 because that helps you solve for x

Equation: x^2 = ± 116/4

116/4 = 29

Answer: x = √29 OR x = √-29

Good luck on your assignment and enjoy your day!

Answer:

Step-by-step explanation:

Here are your Explanations

Step 1

4x2 – 121 + 5 = 0  obsere the questions

Step 2

4x2 – 121 + 5 = 0  Simplify

4x2−116=0

Step 3

4x2−116=0  Add 116 to the sides

4x2=116

Step 4

4x2=116  Divide the sides by 4

x=29  Then you take the square root

Answer : sqrt29 or -sqrt29

=============================================================

Explanation:

2x + 4y < 16 solves to y < -0.5x+4 when you isolate y. The inequality sign does not change direction because we divided both sides by a positive value (in this case, 4).

The graph of y < -0.5x+4 will be the same as the graph of 2x+4y < 16

To graph y < -0.5x+4, we graph y = -0.5x+4 which is a straight line that goes through the two points (0,4) and (2, 3). This is the boundary line of the inequality shaded region. The boundary line is a dashed line because we are not including points on the boundary that are part of the solution set. We only include these boundary points if the inequality sign has "or equal to".

We then shade below the dashed boundary line to indicate points below the boundary line. The shading is done downward due to the "less than" sign.

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

Perhaps another method to find what direction we shade is we can try out a point like (0,0). The point cannot be on the boundary line.

Plug those coordinates into either equation. I'll pick the second equation

y < -0.5x+4

0 < -0.5*0+4

0 < 0+4

0 < 4

The last inequality is true, so the first inequality is also true when (x,y) = (0,0). Therefore, the point (0,0) is in the shaded region. The point (0,0) is below the boundary line y = -0.5x+4

So this is another way to see that the shaded region is below the boundary line.

Answer:

D

Step-by-step explanation:

Well, I can tell the answer just by looking:

- The shape moved counterclockwise by one quadrant

- The shape got SMALLER

- Rotations go counterclockwise. So that's a 90 degree rotation.

- Shape gets smaller so it's dilated by a number less than 1. Dilate by 1/2

Step 1: We make the assumption that 498 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x​.

Step 3: From step 1, it follows that $100\%=498$100%=498​.

Step 4: In the same vein, $x\%=4$x%=4​.

Step 5: This gives us a pair of simple equations:

$100\%=498(1)$100%=498(1)​.

$x\%=4(2)$x%=4(2)​.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{498}{4}$

100%

x%​=

498

4​​

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{4}{498}$

x%

100%​=

4

498​​

$\Rightarrow x=0.8\%$⇒x=0.8%​

Therefore, $4$4​ is $0.8\%$0.8%​ of $498$498​.

Answer:

$180.806

Step-by-step explanation:

The computation of the total amount paid for the trip is shown below;

As we know that

Simple interest = Principal × rate of interest × time period

= (67.70 + 62.34 + 45.50) × 12% × 3 months ÷ 12 months

= 5.2662

Now the amount is

= Principal + simple interest

= 175.54 + 5.2662

= $180.806

Answer:

89.8 feet

Step-by-step explanation:

In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.

We would solve the above question using Sine rule

The formula is given as:

DB/sin D = BC/sin B

93/sin 90 = BC/sin 75

We cross multiply

sin 90 × BC = 93 × sin 75

BC = 93 × sin 75/sin 90

BC = 89.83 feet

Approximately BC = 89.8 feet

[tex]\huge\boxed{\sf 18 cm\²}[/tex]

Step-by-step explanation:

The figure consists of 2 rectangles.

Rectangle 1 Area:

Length = 5 cm

Width = 2 cm

Area = Length * Width

A = 5 * 2

A = 10 cm²

Rectangle 2 Area:

Length = 4 cm

Width = 2 cm

Area = 2 * 4

A = 8 cm²

Area of the whole figure:

= Rectangle 1 + Rectangle 2

Answer:

x = 7 cm

Step-by-step explanation:

12x9 + 3x = 129

108 + 3x = 129

3x = 21

x = 7 cm

The value of x will be;

⇒ x = 2.3 cm

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The shape has area 129 cm².

Now,

Since, The shape has area 129 cm².

And, The Length of the large rectangle = (12 + x) cm

And, The width of the rectangle = 9 cm

We know that;

The area of rectangle = Length × Width

⇒ 129 = (12 + x) × 9

⇒ 129/9 = 12 + x

⇒ 14.3 = 12 + x

⇒ x = 14.3 - 12

⇒ x = 2.3 cm
