Answer:
X = -1 Y = 4
Step-by-step explanation:
Put the 7y over so it is 27-7y
after that you fill in the x on the top formula with (27-7y)
From there you solve like normal for Y, which ends out being 4.
Once you have that you can plug 4 into the Y spot in the bottom formula and just solve for X

Using Pythagorean theorem
By applying Pythagorean's theorem to right-angled triangle PQR, the length of segment PQ is equal to [tex]\sqrt{29}[/tex] units.
In Mathematics and Geometry, Pythagorean theorem is an Euclidean postulate that can be modeled or represented by the following mathematical equation:
[tex]c^2=a^2+b^2[/tex]
Where:
a is the opposite side of a right-angled triangle.b is the adjacent side of a right-angled triangle.c is the hypotenuse of a right-angled triangle.By applying Pythagorean's theorem to right-angled triangle PQR, the length of segment PQ can be calculated as follows;
[tex]PQ^2=QR^2+PR^2\\\\PQ^2=2^2+5^2\\\\PQ^2=4 + 25\\\\PQ=\sqrt{29}[/tex]units.
Convert this equation to slope-intercept form:
25x + 10y = 1,000
Answer:
y = -2.5x +100
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
We need to solve for y
25x+ 10y =1000
Subtract 25x from each side
25x-25x+10y = -25x +1000
10y = -25x+1000
Divide each side by 10
10y/10 = -25x/10 +1000/10
y = -2.5x +100
Answer:
y = -2.5x + 100
Step-by-step explanation:
25x + 10y = 1,000
10y = -25x + 1000
y = -2.5x + 100
a drum have a diameter of 22 in and a 16 in deep find the volume of this drum
≈ 6079 in³
Step-by-step explanation:drum = cylinder
d = 2r => r = d/2 = 22in/2 = 11 in
h = 16 in
V = π·r²·h
= 3.14·(11in)²·16in
= 3.14·121in²·16in
= 6079, 04 in³
≈ 6079 in³

Write an equation that is perpendicular to y=4x- 10 and goes through the point (4,2)
Answer:
y = (-1/4)x + 3
Step-by-step explanation:
The slope of our equation is 4, so to find the slope of the perpendicular equation, we have that:
m1 * m2 = -1
Where m1 is the slope of the first equation and m2 is the slope of the perpendicular equation.
So, we have that:
4 * m2 = -1
m2 = -1/4
So the second equation is y = (-1/4)x + b
If the second equation goes through the point (4,2), for x = 4 we have y = 2, then:
2 = (-1/4)*4 + b
2 = -1 + b
b = 3
So the perpendicular equation is:
y = (-1/4)x + 3

Find the value of r in the following diagram.
The value of r is 3.75 from the diagram.
We have to find the value of r which is a radius.
ABC is a right angle triangle in the circle.
We find the value of r by using pythagoras theorem.
r²+9²=(6+r)²
r²+9²=36+12r+r²
9²=36+12r
81=36+12r
Subtract 36 from both sides:
81-36=12r
45=12r
Divide both sides by 12:
r=45/12
r=3.75
Hence, the value of r is 3.75.

What is the area of the following parallelogram in square centimeters?
396 cm2
360 cm2
3.6 cm2
3.96 cm2
Answer:
3.6 cm²
Step-by-step explanation:
18 mm = 1.8 cm
A = 2cm×1.8cm = 3.6 cm²
Your answer would be the third option, 3.6 cm².
The equation for the area of a parallelogram is the same for the area of a rectangle, which is base multiplied by perpendicular height. Because all of the answers are given in cm², we should convert all lengths in mm to cm.
This means that 18mm because 1.8cm (by dividing by 10).
Now we just do 1.8 × 2 = 3.6cm²

A group of 59 randomly selected students have a mean score of 29.5 with a standard
deviation of 5.2 on a placement test. What is the 90% confidence interval for the mean
score, ", of all students taking the test?
Answer:
[tex]29.5-1.671\frac{5.2}{\sqrt{59}}=28.37[/tex]
[tex]29.5+1.671\frac{5.2}{\sqrt{59}}=30.63[/tex]
And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence
Step-by-step explanation:
Information given
[tex]\bar X = 29.5[/tex] represent the sample mean
[tex]\mu[/tex] population mean
s= 5.2 represent the sample standard deviation
n=59 represent the sample size
Confidence interval
The confidence interval for the true mean is given by the following formula:
[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex] (1)
The degrees of freedom are given by:
[tex]df=n-1=59-1=58[/tex]
The Confidence interval is 0.90 or 90%, the significance is [tex]\alpha=0.1[/tex] and [tex]\alpha/2 =0.05[/tex], and the critical value is [tex]t_{\alpha/2}=1.671[/tex]
Now we have everything in order to replace into formula (1):
[tex]29.5-1.671\frac{5.2}{\sqrt{59}}=28.37[/tex]
[tex]29.5+1.671\frac{5.2}{\sqrt{59}}=30.63[/tex]
And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence

The Exterior Angle Theorem states that basically ∠ACB and ∠ACD are supplementary, meaning they should equal 180 when added together. Since you know one side of the whole angle is 35, simply do 180-35, which equals 145°.
Solve x :
[tex]{(3 {x}^{2} - 8x + 5)}^{x + 1} = 1[/tex]
We want this expression to fall in one of the two cases:
[tex]\alpha ^ 0 = 1 = 1^\beta[/tex]
So, if the exponent is zero, the base can assume any value, because everything (expect zero) to the power of zero is one.
Similarly, if the base is 1, the exponent can be any number, becuase 1 raised to any exponent is still one.
If we are looking for the "zero exponent" strategy, we simply have to impose
[tex]x+1=0\iff x=-1[/tex]
In this case, the expression becomes [tex]16^0=1[/tex], so we avoided the [tex]0^0[/tex] case and we're good.
If we are looking for the "base equals one" strategy, we must impose
[tex]3x^2-8x+5 = 1 \iff 3x^2-8x+4=0 \iff x=\dfrac{2}{3}\lor x=2[/tex]
Answer:
x = -1, ⅔, 2
Step-by-step explanation:
3x² - 8x + 5
3x² - 3x - 5x + 5
3x(x - 1) - 5(x - 1)
(3x - 5)(x - 1)
[3x² - 8x + 5]^(x+1) = 1
The ourput is 1 when:
1) The power is 0
x + 1 = 0
x = -1
2) base is 1
3x² - 8x + 5 = 1
3x² - 8x + 4 = 0
3x² - 6x - 2x + 4 = 0
3x(x - 2) - 2(x - 2) = 0
(3x - 2)(x - 2) = 0
x = 2 , ⅔
Therefore, 3 solutions
x = -1, ⅔ , 2

3.Can we multiply a 2x3 matrix by a 3x2 matrix? If yes, what dimensions will the product matrix AB have ?
Answer:
Yes, the dimensions will be 2x2
Step-by-step explanation:
When multiplying matrices you have AxB by CxD. You can only multiply matrices if the inner number is the same.
Ex. 2x3 by 3x2 or QxD by DxW
The dimensions of the result will depend on the outer numbers.
Ex. 2x3 by 3x2 has a 2x2 result or QxD by DxW has a QxW result
Yes, you can multiply a 2x3 matrix by a 3x2 matrix. The result will be a 2x2 matrix because the number of rows in the first matrix and the number of columns in the second matrix define the dimensions of the product matrix.
Explanation:Yes, it is possible to multiply a 2x3 matrix by a 3x2 matrix. When multiplying matrices, the number of columns in the first matrix must be the same as the number of rows in the second matrix. Therefore, in this case, where we have a 2x3 matrix and a 3x2 matrix, the 3 columns in the first matrix and the 3 rows in the second matrix make multiplication possible.
The resulting product from the multiplication of these two matrices will be a new matrix whose dimensions are determined by the number of rows in the first matrix and the number of columns in the second matrix. In this case, as the first matrix has 2 rows and the second matrix has 2 columns, the resulting matrix will have dimensions of 2x2.
