Answer:
x=28
Step-by-step explanation:
I am assuming the mean is arithmetic mean. So we first add up the numbers:
6+10+12+18+16+x
=22+10+30+x
=22+40+x
=62+x
Then since there's 6 numbers in total, we have an equation:
[tex]\frac{62+x}{6}=15\\62+x=90\\x=28[/tex]
The answer is 28!
Have a nice day! :)

6 cm
9 cm
x cm
The shape has area 129 cm
Work out the value of x.
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
What is mean by Rectangle?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

A family charges a trip to the zoo on a credit card. The simple interest rate is 12%. The charges are paid after 3 months. What is the total amount paid for the trip? Round your answer to the nearest hundredth.
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

[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

| 4x2 – 121 + 5 = 0 ?
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

The Paks bought 4 lunches for $16. The McGills bought 6 lunches for $24. The Manns bought 15 lunches for $60. The relationship of lunches to cost is a proportional relationship. What is the constant of proportionality? A. B. C. 4 D. 64
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
0.8) 498 what is the answer
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.

Which of the following describes the graph of 2x + 4y < 16?
dashed line, shaded below
solid line, shaded above
solid line, shaded below
dashed line, shaded above
=============================================================
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.
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.
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
A designer decides to create a larger scale model of a smart phone so that his team can work more easily on the design. The length of the screen of his model is 60 centimeters, which is 2.5 times longer than it is wide. The designer asked his team to build the screen of the actual phone with a width of 6 centimeters. What is the scale factor of the model phone to the actual phone?
Answer:
The length of the model is 250% of the width and is 60 centimeters, and the width of the actual phone is 6 so it has a scale factor of 4:1.

Metaphors:
The sky is a blanket of stars
His words are daggers
Similes:
The sky is like a blanket of stars
His words are as sharp as daggers
His words are live daggers
We have,
Metaphors and similes are both figures of speech used to make comparisons between two unrelated things.
They create vivid and imaginative descriptions by equating or likening one thing to another.
Metaphors directly state that one thing is another thing, without using "like" or "as."
They make a direct comparison by asserting that something is something else.
For example, "The sky is a blanket of stars" compares the sky to a blanket of stars, implying that the sky is vast and filled with numerous stars.
Similes, on the other hand, use "like" or "as" to make a comparison between two things.
They highlight similarities by stating that one thing is like or resembles another thing.
For instance, "The sky is like a blanket of stars" implies that the sky shares some characteristics with a blanket of stars, such as its vastness and the sense of being covered.
Thus,
Metaphors:
The sky is a blanket of stars
His words are daggers
Similes:
The sky is like a blanket of stars
His words are as sharp as daggers
His words are live daggers
