The average of 6 quiz scores, where [tex]x[/tex] is the score of the last quiz, is
[tex]\dfrac{83+81+89+92+80+x}6=\dfrac{425+x}6[/tex]
The student needs a minimum average of 86 to earn an A:
[tex]\dfrac{425+x}6=86\implies425+x=516\implies x=91[/tex]
so the student needs a score of 91.
The length of a rectangle is 2 inches more than its width. The perimeter of the rectangle is 24 inches. The equation 2x + 2(x + 2) = 24, where x is the width in inches, represents this situation. The value of x from the set {1, 3, 5, 7} that holds true for the equation is . So, the width of the rectangle is inches and its length is inches.
Answer:
Width is 5 and length is 7
Step-by-step explanation:
You can solve the equation using the distributive property and inverse operations.
2x +2(x+2)=24
2x + 2x + 4 = 24
4x + 4 = 24
4x = 20
X = 5
This means the width is 5 and the length is 7.
The width of the rectangle is 5 inches and its length is 7 inches.
Explanation:The given equation 2x + 2(x + 2) = 24 represents the situation with a rectangle's length being 2 inches more than its width and the perimeter of the rectangle being 24 inches. To find the value of x from the set {1, 3, 5, 7} that holds true for the equation, we can substitute each value into the equation and solve for x. By trying each value, we find that x = 5 holds true for the equation.
Therefore, the width of the rectangle is 5 inches and since the length is 2 inches more than the width, the length would be 7 inches.
Use the net as an aid to compute the surface area of the triangular prism. A) 550m^2 B) 614m^2 C) 670m^2 D) 790m^2
Answer:
The correct answer is option D. 790 m²
Step-by-step explanation:
Formula:-
Area of triangle = bh/2
Area of rectangle = bh
where b - Base and h - Height
To find the area of prism
Area of prism = Base area + side rectangle area + side triangle area
= (16 * 11) + (2 * 11 * 17) + (2 * 16 * 15 /2)
= 176 + 374 + 240
= 790 m²
Therefore the correct answer is option D. 790 m²
The surface area of the triangular prism is 790m². ( option D)
A triangular prism is a type of prism with triangular base. The surface area of a prism is expressed as ;
SA = 2B + ph
where , B is the base area and p is the perimeter of the base.
Base area = 1/2bh
where b is the base and h is the height
= 1/2 × 16 × 15
= 8 × 15
= 120m²
Perimeter = 17 + 16 + 17 = 50m²
Surface area = 2 × 120 + 50 × 11
= 240 + 550
= 790 m²
Therefore, the surface area of the prism is 790m²

find the area of the composite figure... please help
Answer:
27.5 square yards
Step-by-step explanation:
So, we have two shapes connected together and we want to know the combined area of the two. All we have to do is find out the area of each one, then add the results.
First, the rectangle:
The area of a rectangle is the base multiplied by the height, so
A = 6 x 4 = 24 square yards
Then, the half-circle.
We know the area of a circle is calculated with A = π * r², so the area of a half circle will be A = (π * r²)/2.
We know the circle has a diameter of 3 yards because the wall next to it is also 3 yards and the whole structure is 6 yards wide, so...
A = (π (1.5)²)/2 = 2.25 π / 2 = 3.53 square yards
Overall, we have
Area of the rectangle: 24 square yards
Area of the half-circle: 3.53 square yards
Total: 27.53 square yards, rounded to the tenth: 27.5 square yards.
Answer:
27.5 yards^2
Step-by-step explanation:
We are given a figure which comprises of two shapes: a rectangle and a semicircle and we are to find the area of this composite figure.
We know that the area of these two shapes is given by the following formulas so we will put in the given values to get:
Area of rectangle = [tex]length \times width[/tex] = [tex]6 \times 4[/tex] = 24 yd^2
Area of semi-circle = [tex]\frac{\pi r^2}{2}[/tex] = [tex]\frac{3.14 \times 1.5^2}{2}[/tex] = 3.53 yd^2
Area of composite figure = [tex]24+3.53[/tex] = 27.5 yards^2

daily high temperatures recorded in certain areas 65 degrees Fahrenheit 66 degrees Fahrenheit 70 degrees Fahrenheit is 58° Fahrenheit and 61 degrees Fahrenheit what is the mean absolute deviation for the data
Answer:
3.64
Step-by-step explanation:
65 + 66 + 70 + 58 + 61 = 319
319/5 = 63.8
65 - 63.8 = |1.2|
66 - 63.8 = |2.2|
70 - 63.8 = |6.2|
58 - 63.8 = |-5.8| = 5.8
61 - 63.8 = |-2.8| = 2.8
1.2 + 2.2 + 6.2 + 5.8 + 2.8 = 18.2

.45 is 1/10 of what decimal?
Answer:
4.5
Step-by-step explanation:
To get the answer, you have to multiply the number 0.45 by the denominator of 1/10. [The denominator is 10.]The reason for this is because 10 is the whole number of parts. When you multiply 1/10 x 0.45, you get 4.5 [Just move the decimal point one place to the right because 10 has one zero.]
To double check your answer, divide 4.5 by 10 or multiply 4.5 x 1/10. Either way you get 4.5, so that's the correct answer.

Simplify the expression (5k^2)^3
(5k^2)^3 simplifies to 125k^6.
To simplify the expression (5k^2)^3, we can apply the exponent rule. The rule states that when raising a power to another power, we multiply the exponents together.
In this case, we have (5k^2)^3. To simplify, we raise both the base, 5, and the exponent, k^2, to the third power.
First, let's raise the base, 5, to the third power:
5^3 = 5 x 5 x 5 = 125
Next, let's raise the exponent, k^2, to the third power:
(k^2)^3 = k^(2 x 3) = k^6
Therefore, (5k^2)^3 simplifies to 125k^6.

Answer:
Mean : 95
Median : 85
Mode : 90
Part B : Impossible
Step-by-step explanation:
We can make an equation to find the mean using the first 5 history test scores.
[tex]85=\frac{80+75+90+75+95+n}{6} \\ \\ 85=\frac{415+n}{6} \\ \\ 510=415+n \\ \\ n=95[/tex]
So a 95 would be needed to have a mean of 85.
Next, the median.
First, we sort the first 5 history scores from least to greatest.
We get 75, 75, 80, 90, 95.
Since, 80 is the middle value, it will be used in the calculation of the median.
We can make an equation with this.
[tex]82.5=\frac{80+n}{2} \\ \\ 165=80+n \\ \\ n=85[/tex]
So a score a 85 would be needed to have a median of 82.5
Thirdly, the mode.
Since 90 is already in the set once, we can just have Maliah score another 90 to make 90 the mode (with the exception of 75 of course).
Finally, Part B.
We can use the equation we had for the first mean calculation but change 85 to 90.
[tex]90=\frac{80+75+90+75+95+n}{6} \\ \\ 90=\frac{415+n}{6} \\ \\ 540=415+n \\ \\ n=125[/tex]
So Maliah would need a score of 125 to make her mean score 90, but since the range is only from 0-100, it is impossible.
I will mark brainliest, Please answer d). How do I do this question and what is the answer.
So far I have done:
3d - 11/4 +11/4 = 3/2 + 11/4
3d = 3/2 + 11/4
How do I find a common denominator? Can someone explain how I would find a common denominator in this question.
The lowest common denominator of the two fractions is 4 because it is the smallest number that both fractions can be transformed into. 3/2 is multiplied by 2 to create 6/4 which can be added to 11/4.
we could add the left-side and then cross-multiply and so on, OR we can simply get the LCD of all denominators, in this case 4,2 so our LCD will just be 4, and multiply both sides by 4, that way doing away with the denominators, so let's do so
[tex]\bf 3d-\cfrac{11}{4}=\cfrac{3}{2}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{4}}{4\left( 3d-\cfrac{11}{4} \right)=4\left( \cfrac{3}{2} \right)}\implies 12d-11=6 \\\\\\ 12d=17\implies d=\cfrac{17}{12}\implies d=1\frac{5}{12}[/tex]

what is the area of the figure:
For this case we have that the area of the triangle is given by:
[tex]A = \frac {b * h} {2}[/tex]
Where:
b: It's the base
h: It's the height
We have to:
[tex]cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}[/tex]
The atura will be given by:
[tex]sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}[/tex]
So, the area is:
[tex]A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144[/tex]
Answer:
144
Answer:
Area=144
Step-by-step explanation:
In right triangle ABC,
[tex]\sin\left(45^o\right)=\frac{BC}{AB}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{BC}{24}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{Height}{24}[/tex]
[tex]\frac{24}{\sqrt{2}}=Height[/tex]
[tex]Height=\frac{24}{\sqrt{2}}[/tex]
similarly
[tex]\cos\left(45^o\right)=\frac{AC}{AB}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{AC}{24}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{Base}{24}[/tex]
[tex]\frac{24}{\sqrt{2}}=Base[/tex]
[tex]Base=\frac{24}{\sqrt{2}}[/tex]
Then area of right triangle [tex]=\frac{1}{2}\left(Base\right)\left(Height\right)[/tex]
[tex]=\frac{1}{2}\left(\frac{24}{\sqrt{2}}\right)\left(\frac{24}{\sqrt{2}}\right)[/tex]
[tex]=\frac{576}{4}=144[/tex]
Hence Area=144

In a survey 3/4 of 400 parents said yes, they give their children fruit snack. How many answered yes to the survey?
300 parents
3/4 = x/400, and we are trying to find x.
Multiply the numerator and denominator of 3/4 each by 100 to make the denominator equal 400. This gives 300/400. So, 300/400 = x/400.
Multiply both sides of the equation by 400 to cancel out the division. This gives you 300 = x, so 300 parents said yes to the survey.
On a certain day, the temperature changed at a rate of -2 degrees Fahrenheit per hour. How long did it take for the change in temperature to be -14 degrees Fahrenheit
Answer:
7 hours.
Step-by-step explanation:
Pretty easy. 14 divided by 2. To check the answer, 2 x 7 = 14.
When the temperature change rate is -2 degrees Fahrenheit per hour, it takes 7 hours for the temperature to drop by -14 degrees Fahrenheit.
Explanation:The question asks us to determine the time it took for the temperature to drop by -14 degrees Fahrenheit when the rate of temperature change was -2 degrees Fahrenheit per hour. This can be solved using a simple equation of rate × time = change in quantity. As the rate is -2 degrees Fahrenheit per hour and the total temperature drop is -14 degrees Fahrenheit, the equation becomes -2 × time = -14. To solve for time, divide the total temperature change by the rate of change. Substituting the values into the equation gives: time = -14 / -2. Thus, the time it took for the temperature to drop by -14 degrees Fahrenheit was 7 hours.
