Hi Please help! this is math and coding soooo ye
Answers
Answer:
49
Step-by-step explanation:
Cube 7 to get the volume.(343)
Do 7^2 to get 49, then multiply by 6 to get the surface area(294)
Then subtract 343-294=49
The volume = 343
The surface area = 294
To calculate this in code you could just use
print(343-294);
Or you can use this
(You can swap out the 7s for the variable length)

Jamal decides he wants to shop around for the best price for purchasing an advertisement space in a newspaper. One of the companies he contacts charges $2.00 for each line in the advertisement and an initial fee. For the 3 lines he needs, the company will charge $14.00. Which equation best represents this scenario if y is the cost for an ad with x lines?
Answers
Answer:
Y = $2x + 8
Step-by-step explanation:
Variable cost per line = $2.00
For 3 lines, the Variable cost = $2 x 3 = $6
Total cost for 3 lines = $14.00
Fixed Charges = $14 - $6 = $8
Using the formula, total cost, Y = $2x + $8 = $14
Where x = number of lines needed.
Therefore, total cost, Y = ($2 x 3) + $8 = $14
Quadrilateral ABCD is inscribed in a circle

Answers
Answer:
Quadrilateral ABCD is inscribed in a circle, then
A + C = 180
=> 2x + 9 + 3x + 1 = 180
=> 5x = 170
=> x = 34
=> A = 2 x 34 + 9 = 77 deg
Hope this helps!
:)
Answer:
77°
Step-by-step explanation:
ABCD is inscribed in a circle. Therefore it is a cyclic quadrilateral. Opposite angles of a cyclic quadrilateral are supplementary.
[tex]\therefore \angle A + \angle C = 180° \\ (2x + 9) \degree + (3x + 1) \degree =180° \\ (5x + 10) \degree =180° \\ 5x + 10 = 180 \\ 5x = 180 - 10 \\ 5x = 170 \\ x = \frac{170}{5} \\ x = 34 \\ \angle A = (2 \times 34 + 9) \degree \\ \huge \red{ \boxed{\angle A= 77 \degree}} \\ [/tex]

6 The midpoint of the line segment joining
Alh, 4) and B(-5, k) is M(3,-2). Find
(a) the values of h and k,
(b) the equation of the perpendicular
bisector of the line segment AB.
Answers
Answer:
Question A, the values of h is 11 and k is -8 .
Question B, the equation is y = (-4/3)x + 2 .
Step-by-step explanation:
Question A, in order to find the value of h and k, you have to use the mid-point formula and do comparison :
[tex]m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
Let (x1,y1) be coordinate A (h,4),
Let (x2,y2) be coordinate B (-5,k),
Let mid-point be (3,-2),
[tex](3 \: , - 2) = ( \frac{h - 5}{2} , \frac{4 + k}{2} )[/tex]
[tex]by \: comparison, \: [/tex]
[tex] \frac{h - 5}{2} = 3[/tex]
[tex]h - 5 = 6[/tex]
[tex]h = 11[/tex]
[tex] \frac{4 + k}{2} = - 2[/tex]
[tex]4 + k = - 4[/tex]
[tex]k = - 8[/tex]
Question B, given that line is perpendicular bisetor to AB means that the line touches mid-point which is M(3,-2). Using gradient formula :
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
Let (x1,y1) be (11,4),
Let (x2,y2) be (-5,-8),
[tex]m = \frac{4 - ( - 8)}{11 - ( - 5)} [/tex]
[tex]m = \frac{12}{16} [/tex]
[tex]m = \frac{3}{4} [/tex]
The gradient of perpendicular line is opposite of line AB and when both gradient are multiplied, you should get -1 :
[tex]m1 \times m2 = - 1[/tex]
Let m1 be the gradient of AB, m = 3/4,
Let m2 be the gradient of perpendicular line,
[tex] \frac{3}{4} \times m2 = - 1[/tex]
[tex]m2 = - \frac{ 4}{3} [/tex]
Last, we have to use the slope-form equation, y = mx + b and susbtitute the coordinates of M into the equation :
[tex]y = mx + b[/tex]
Let m = -4/3,
Let x = 3,
Let y = -2,
[tex] - 2 = - \frac{4}{3} (3) + b[/tex]
[tex]b = 2[/tex]

Suppose that the mean time that visitors stay at a museum is 94.2 minutes with a standard deviation of 15.5 minutes. The standard error of the mean,ox, is 3.1. A random sample of 25 of the times chosen. What interval captures 68% of the means for random samples of 25 scores?
Answers
Answer:
[tex] 94.2 -0.994*3.1 = 91.1186[/tex]
[tex] 94.2 +0.994*3.1 = 97.2814[/tex]
And the 68% confidence interval is given by (91.1186, 97.2814)
Step-by-step explanation:
For this case we know that mean time that visitors stay at a museum is given by:
[tex] \bar X = 94.2 [/tex]
The standard deviation is given by:
[tex] s= 15.5[/tex]
And the standard error is given by:
[tex] SE = \frac{s}{\sqrt{n}} =3.1 [/tex]
And we want to interval captures 68% of the means for random samples of 25 scores and for this case the critical value can be founded like this using the normal standard distribution or excel:
[tex] z_{\alpha/2}= \pm 0.994[/tex]
We can find the interval like this:
[tex] \bar X \pm ME[/tex]
And replacing we got:
[tex] 94.2 -0.994*3.1 = 91.1186[/tex]
[tex] 94.2 +0.994*3.1 = 97.2814[/tex]
And the 68% confidence interval is given by (91.1186, 97.2814)

Hilda is taking out an $11,000 personal loan that she will repay in 5 years. If she receives a 10% interest rate, her monthly payments will be $233.72. If she receives and 18% interest rate her monthly payments will be $279.33. How much less interest will Hilda pay if she qualifies for the lower interest rate? *
Answers
Answer:
Hilda would pay $ 2,736.60 less interest
Step-by-step explanation:
The total interest payment is the total repayments for 5 years less the initial loan amount
If the interest rate is 10% Hilda repays $233.72 for 5 years multiplied by 12 months:
total repayment=$233.72*5*12=$ 14,023.20
Interest =$14,023.20-$11,000.00=$3.023.20
If the interest rate is 18% Hilda repays $279.33 for 5 years multiplied by 12 months:
total repayment=$279.33*5*12=$ 16,759.80
Interest =$16,759.80 -$11,000.00=$5759.8
Difference in interest payments=$5759.8 0-3.023.20=$ 2,736.60
If a 30-foot ladder leaning against a building makes a 62° with the ground. How many feet from the base of the building is the bottom of the ladder? Assume you hired an excellent contractor, and your building's wall is perpendicular to the ground. Round to the nearest tenth of a foot.
Answers
Answer: 14.1 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the trigonometric functions.
cos α = adjacent side / hypotenuse
Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the adjacent side (x) is the distance from the base of the building to the bottom of the ladder
Replacing with the values given:
cos 62 = x/ 30
Solving for x
cos62 (30) =x
x= 14.1 feet

Three solid shapes, A, B and C are similar.
The surface area of shape A is 9cm^2
The surface area of shape B is 16cm^2
The ratio of the volume of shape B to the volume of shape C is 27 : 125
Work out the ratio of the height of shape A to the height of shape C.
Give your answer in its simplest form.
Answers
Answer:
A:C = 9:20
Step-by-step explanation:
The ratio of the surface area of similar solid is equal to the square of the ratio of their corresponding linear measures. If the ratio of their corresponding linear measures is a:b, the surface area ratio will be (a/b)². Therefore,
(A/B )² = 9/16
square root both sides
A/B = √9/√16
A/B = 3/4
A:B = 3:4
The ratio of volume of two similar solid is the ratio cube of their corresponding linear measures. Therefore,
(B/C)³ = 27/125
cube root both sides
B/C = 3/5
B:C = 3:5
To make the ratio equivalent
A:B:C = 9:12:20
A:C = 9:20
