Answer:
the solution of the system is:
x = 1 and y = 2.
Step-by-step explanation:
I suppose that we want to solve the equation:
-6*x + 6*y = 6
6*x + 3*y = 12
To solve this, we first need to isolate one of the variables in one of the equations.
Let's isolate y in the first equation:
6*y = 6 + 6*x
y = (6 + 6*x)/6
y = 6/6 + (6*x)/6
y = 1 + x
Now we can replace this in the other equation:
6*x + 3*(1 + x) = 12
6*x + 3 + 3*x = 12
9*x + 3 = 12
9*x = 12 - 3 = 9
x = 9/9 = 1
Now that we know that x = 1, we can replace this in the equation "y = 1 + x" to find the value of y.
y = 1 + (1) = 2
Then the solution of the system is:
x = 1 and y = 2.

Answer:
D
Step-by-step explanation:
At least 30 minutes, so this means 30 minutes and above. Now add the probabilities starting from 30
1/4 + 1/4 + 1/8 + 1/16 = 11/16
You are conducting a significance test of H0: μ = 5 against Ha: μ > 5. After checking the conditions are met from a simple random sample of 30 observations, you obtain t = 2.35. Based on this result, describe the p-value.
The p-value falls between 0.15 and 0.2.
The p-value falls between 0.025 and 0.05.
The p-value falls between 0.01 and 0.02.
The p-value falls between 0.005 and 0.01.
The p-value is less than 0.005.
Answer:
The p-value falls between 0.005 and 0.01.
Step-by-step explanation:
Random sample of 30 observations, you obtain t = 2.35
This means that the pvalue is 1 subtracted by the pvalue of Z = 2.35, as we are testing that the mean is more than a value.
Looking at the z-table, z = 2.35 has a pvalue of 0.9906
1 - 0.9906 = 0.0094
So, between 0.005 and 0.01.
Answer: The p-value falls between 0.01 and 0.02.

Two sides of a quadrilateral have the same length, x, while
the other two sides have the same length, both being the next
consecutive odd integer. Write the sum of these lengths. Then
simplify this expression.
?
Answer:
Step-by-step explanation:
It sounds as though x is odd. The other two sides have length x+2. Perimeter of quadrilateral = 2x + 2(x+2) = 4x + 4
Marissa claims that stacking 6 blocks with dimensions of One-half times 1 times 1 will give the same volume as stacking 9 blocks with dimensions of One-third times 1 times 1. Which statements about her claim are true? Check all that apply. Six of the one-half cubes would have a volume of 3 cubic units. Nine of the one-third cubes would have a volume of 6 cubic units. Since One-half and One-third do not have common factors, stacks of one-half cubes and stacks of third-cubes could never have the same volume. Three of the one-third cubes will make 1 unit cube. Two of the one-half cubes will make 1 unit cube. Both stacks will have a volume of 3 cubic units.
Answer:
correct choices:
six of the one-half cubes would have a volume of 3 cubic units.
three of the one-third cubes will make 1 unit cube.
two of the one-half cubes will make 1 unit cube.
both stacks will have a volume of 3 cubic units.

The measure of UW is
type your answer...
Answer:
9
Step-by-step explanation:
UT^2 = UV * UW
6^2 = (x - 7)(x - 7 + 5)
36 = (x - 7)(x - 2)
36 = x^2 - 2x - 7x + 14
x^2 - 9x - 22 = 0
(x - 11)(x + 2) = 0
x - 11 = 0 or x + 2 = 0
x = 11
UW = x - 7 + 5
UW = 11 - 7 + 5
UW = 9
Write an equation of the line with the given slope and y-intercept:
m = -5,6 = 4
a. y = -5x + 4
b. y = 5x + 4
c. y = -5x-4
d. y = 5x - 4
Please select the best answer from the choices provided
Ο Ο Ο Ο
D
Answer:
a. y = -5x + 4
Step-by-step explanation:
Given the following data;
Slope, m = -5
Intercept, c = 4
Mathematically, the equation of line is given by the formula; y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the given parameters, we have;
y = -5x + 4
The circumference of a circle is 7π in. Find its radius, in inches.
Answer:
3.5 in
Step-by-step explanation:
Circumference = 2π(radius)
7π = 2π (radius)
7π/2π = radius
Pi in numerator and denominator cancel each other.
7/2 = radius
3.2 in = radius
Answer:
[tex] \bf \huge \: 11 \: inches.[/tex]
Step-by-step explanation:
Given :The circumference of a circle is 7π in.to find :Find its radius, in inches.formula used :r = c/2where,
r = radius c = circumference explanation :⟼ r = c/2
⟼ r = 7×22÷7/2 in
⟼ r = 22/2 in
⟼ r = 11 in.
Hence, radius is 11 inches.write the log equation as an exponential equation

Answer:
[tex]5 + 7x \le 33[/tex]
Step-by-step explanation:
Given
[tex]Base\ Charge = 5[/tex]
[tex]Additional = 7[/tex] per mile
[tex]Total = 33[/tex]
Required
Determine the inequality
First, we need to determine the total cost for x miles.
[tex]Cost = Base\ Charge + Additional * x[/tex]
[tex]Cost = 5 + 7 * x[/tex]
[tex]Cost = 5 + 7x[/tex]
The total cost can not exceed the amount he has, so the inequality is:
[tex]Cost \le Total[/tex]
[tex]5 + 7x \le 33[/tex]

Answer:
B
Step-by-step explanation:
Area of the Rectangle = L*W
L = 25 cm
W = 14 cm
Area of the rectangle = 25 * 14
Area of the rectangle = 350
Area of the Triangle
Area = 1/2 B * H
B = 25
H = 11
Area = 1/2 *25 * 11
Area = 1/2 275
Area = 137.5
Area of the shaded part = 350 - 137.5
Area of the shaded part = 212.5

Given that the two triangles below are similar , find the values of g and h
Answer:
g = 4
h = 4.5
Step-by-step explanation:
The corresponding sides of two similar figures are proportional to each other.
Therefore,
[tex] \frac{g}{3} = \frac{8}{6} = \frac{6}{h} [/tex]
✔️Find g:
[tex] \frac{g}{3} = \frac{8}{6} [/tex]
Cross multiply
g*6 = 8*3
6g = 24
Divide both sides by 6
g = 24/6
g = 4
✔️Find h:
[tex] \frac{8}{6} = \frac{6}{h} [/tex]
Cross multiply
8*h = 6*6
8h = 36
h = 36/8
h = 4.5
A thermometer falls from a weather
balloon at a height of 7,744 ft. If the
equation for height as a function of time
is h(t) = -16t2 + initial height wheret is
time in seconds and h(t) is height in feet,
how many seconds will it take for the
thermometer to hit the ground?
[?] seconds
Answer:
It will take 22 seconds for the thermometer to hit the ground.
Step-by-step explanation:
A thermometer falls from a weather balloon at a height of 7,744 ft.
This means that the initial height is of 7744ft.
h(t) = -16t2 + initial height
So
[tex]h(t) = -16t^2 + 7744[/tex]
How many seconds will it take for the thermometer to hit the ground?
This is t for which [tex]h(t) = 0[/tex]. So
[tex]0 = -16t^2 + 7744[/tex]
[tex]16t^2 = 0 + 7744[/tex]
[tex]t^2 = \frac{7744}{16}[/tex]
[tex]t = \sqrt{\frac{7744}{16}}[/tex]
[tex]t = 22[/tex]
It will take 22 seconds for the thermometer to hit the ground.

Solve for b 2 in A = h(b 1+b 2), if A = 16, h = 4, and b 1 = 3. b 2 =
Answer:
b2 = 1
Step-by-step explanation:
A = h(b1 + b2)
Given:
A = 16
h = 4
b1 = 3
b2 = x
Work:
A = h(b1 + b2)
16 = 4(3 + x)
16 = 12 + 4x
4x = 16 - 12
4x = 4
x = 1
