Answer:
a) y = 2x - 3 and b) y = -15
Step-by-step explanation:
a) Solve for y
6x - 3y =9
-3y = -6x + 9
Divide by -3, neg/neg = pos
y = 2x - 3
b) x = -6
y = 2x - 3
y = 2(-6) - 3
y = -12 - 3
y = -15

Ima mark as brainlist if u help plsss
Answer:
Hence the disagree with Ima. He used the wrong formula to find the total surface area
Step-by-step explanation:
Surface area of the triangular prism = 2B + pH
B is the base area= 1/2 * 13 * 5
B = 65/2
B = 32.5 m^2
p is the base perimter = 5 + 12 + 13
p = 30m
H is the height of the prism = 8m
Substitute
TSA = 2(32.5) + 30(8)
TSA = 65 + 240
TSA = 305m^2
HEnce the total surface area is 305m^2
Hence the disagree with Ima. He used the wrong formula to find the total surface area
A jacket with an original price of $98.60 is discounted 65%. What is the
Sale Price?
Answer:
34.51
Step-by-step explanation:
It would be 98.60*65% and then subtract that answer with 98.60.
So, we get 34.51
Answer:
$34.51
Step-by-step explanation:
65% discount means 0.65 off
0.65× 98.60=64.09
Meaning $64.09 off
Sale price= 98.60-64.09
$34.51
A number is written in scientific notation.
2.089×105
Which is the same number written in standard notation?
A. 20,890
B. 28,900
C.208,900
D.289,000
Answer:
C. 208,900
Step-by-step explanation:
Scientific notation with a positive exponent:
Start with the decimal number and move the decimal point to the right the same number of places as the exponent. The exponent of 10 is 5.
Start with 2.089
Now add some zeros to the right of the 9.
2.0890000
Now move the decimal point 5 places to the right.
208900.00
The number is 208,900

The perimeter of a parallelogram is 62cm. what is the length of the longest side if the equation of the sides are:-
*3x+5
*x+2
Given
perimeter is 62
Side 1 - 3x+5
Side 2 - x+2
Solution,
2(3x+5+x+2) = 62
4x+7 = 31
4X = 24
x = 6
Now substitute the value of x to get the sides
Side one - 3x+5 = 23cm
Side two - x+2 = 8cm
Answer- the length of the longest side is 23 cm

L 7.8.2 Test (CST): Area, Surface Area, and Volume Question 24 of 30 Find the area of the sector of the circle below. The radius of the circle is 6 cm. Use 3.14 for at 90" O A. 18.84 cm2 O B. 4.71 cm2 O C. 28.26 cm2 O D. 6.22 cm
Answer:
28.26 cm^2
Step-by-step explanation:
Mathematically, we have the area of a sector as;
theta/360 * pi * r^2
theta is the angle subtended at the center of the circle by the sector which is 90 degrees
r is the radius of the circle given as 6 cm
Substituting these values;
90/360 * 3.14 * 6^2 = 28.26 cm^2
What else is true a little help
Answer:
This is a triangular prism.
The surface area is 105 square cm.
This is a square pyramid.

A data set is Normally distributed with a mean of 25 and a standard deviation of 8. If you calculate the standard score of every observation in this data set, the resulting scores will have a distribution that has
Answer:
The answer is "A mean of 0 and a standard deviation of 1".
Step-by-step explanation:
The standard answer of its following formula is calculated by:
[tex]\to z=\frac{X-\mu}{\sigma}[/tex]
Its standard score relates to the sampling distribution with the normal distribution average standard variation of 0 and 1, correspondingly. The mean for a standard scoring is 0, and the normal deviation is 1. that's why the mean=0, standard deviation=1.

a regular sheet of letter (printing) paper measrues 8.5 inches by 11 inches. you want to cut out squares from each corner that it may be folded up to produce an open - top box. What are the dimensions of the square cut outs that will result in a box of maximum volume
Answer:
The dimensions of the square, that will result in a box of maximum volume is a square with side length of approximately 1.585 inches
Step-by-step explanation:
The given dimension of the steel sheet are;
The width = 8.5 inches
The length = 11 inches
Let 'x' represent the side length of the squares cut out, we have;
The length of the box formed, l = 11 - 2·x
The width of the box formed, w = 8.5 - 2·x
The height of the box, h = x
The volume of the box, V = (11 - 2·x) × (8.5 - 2·x) × (x) = 4·x³ - 39·x² + 93.5·x
The maximum or minimum volume is found from dV/dx = 0 at max. or min.
dV/dx = d(4·x³ - 39·x² + 93.5·x)/dx = 12·x² - 78·x + 93.5 = 0
Which gives;
x = (78 ± √((-78)² - 4×12×93.5))/(2 ×12)
x = 4.915 or 1.585
When x = 4.915, V = 4 × 4.915³ - 39 × 4.915² + 93.5 × 4.915 = -7.65
When x = 1.585, V = 4 × 1.585³ - 39 × 1.585² + 93.5 × 1.585 = 66.15
Therefore, the local maximum occurs at x ≈ 1.585
Therefore, the dimensions of the square, 'x' that will result in a box of maximum volume is x ≈ 1.585 inches.

Option C.
how to solve the median
Answer:
1.) Set the data set in the ascending order
2.) Start cancelling out numbers each side, like if u cancel out the first number, then cancel out the last as well.
3.) Keep doing the step 2 until u reach the middle most number.
4.) Sometimes there are 2 middle numbers left, in that case find their average (add both numbers together and divide the sum by 2) which would be ur middle most number.
Hope this helps!

solve the linear equation for x
-4.8(6.3x-4.18)=-58.56
Answer:
x = 81.6/30.24
Step-by-step explanation:
-4.8(6.3x - 4.18) = -58.56
-30.24x + 23.04 = -58.56
-30.24x = -81.6
x = 81.6/30.24
