In triangle ABC, the measure of angle ABC is 51°
and ACB is a right angle. What is the measure of
angle BAC in degrees?
Answer:
39 degrees
Step-by-step explanation:
The sum of angle in the triangle ABC is a80 degrees
m<ACB + <BAC + <ABC =1 80
90 + <BAC + 51 = 180
141 + m<BAC = 180
m<BAC = 180-141
m<BAC = 39 degrees
Hence the measure of m<BAC is 39 degrees
I don´t understand this: Lin’s father is paying for a $20 meal. a) He has a 15%-off coupon for the meal. How much is the discount? You can use the double number line for this problem.
You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.
Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.

Jane worked 38 hours at the grocery store last week and made $296.40. If she works three less hours this week than she did last week, how much will she still make?
Answer:
$273
Step-by-step explanation:
Given data
Jane worked 38 hours at the grocery store last week and made $296.40
she worked 3 hour less= 38-3= 35 hours
Hence if in 38 hours she made $296.40
in 35 hours she will make x
cross multiply
x= 35*296.40/38
x= 10374/38

Transformations on a Map
Use the map of the United States and your centimeter cube to do the following transformations. Pay attention to which axis for reflections.
1. Start in Hawaii on the black-dot.
a. Reflect over the y-axis. Color this square blue. What ocean are you
in?
b. Go back to Hawaii. Now, reflect over the x-axis. Color this square green. What states are you in?
2. Start in Georgia on the black-dot.
a. Reflect over the x-axis. Color this square yellow. What states are you
touching?
b. Go back to Georgia. Now, reflect over the y-axis. Color this square black. What state are you in?
3. Start in Ohio on the square that says Ohio.
Describe a translation that would get you to Montana.
4. Start in Louisiana on the black dot. Rotate 90 degrees counter clockwise. Name a state in the quadrant you land in. (Can you name its capital??)
5. Start in New York on the black dot. Translate left 4 and down 3. Then reflect the cube over the x-axis. Color this square purple. What state are you in?
6. Start in south Dakota on the black dot .
a. Reflect over the x-axis. Color this square orange. What state are
you in?
b. Then reflect your cube over the y-axis. What quadrant are you in?
7. Start in Kansas on the black dot. Reflect over the y-axis and then translate your cube 6 right and 2 up. Color the square pink. What state are you in?
8. Start in New Hampshire on the black dot. Describe a way you could get to any square in the state of Texas. You may need to use more than one transformation to do this.
9. Start in Idaho on the black dot. Translate 6 right and 3 down. Now, reflect your cube over the y-axis. Color the square red. What state are you in?
Then describe the translation that would get you back to Ohio.
10. Start in Mississippi on the black dot. Rotate 90 degrees clockwise. What quadrant are you in?
BONUS: Start in North Carolina on the black dot. Reflect over the y-
axis. Translate 5 up and 4 right. Reflect over the y-axis. Translate 4 down. Rotate 180 degrees counterclockwise. Shade the box.
Answer:
1a.) atlantic
1b.) california
2a.) Tennesee and north carolina
2b.) new mexico
3a.) Add three and reflect accross the x axis
4.) texas (austin), quadrant 3
5.) alabama
6a.) texas
6b.) quadrant 4
7.) penslyvannia
8.) reflect accross x and y axis (or rotate clockwise by 180 degrees) then go 8 right and up 3
9.) missouri
9b.) up 1 and right 3
10.) quadrant 3
bonus.) i colored it gray and it's in wisconsin
Step-by-step explanation:
1a.) to reflect over the y axis you keep the y axis but swap the x to a negative
1b.) to reflect over the x axis you keep the x value the same but y's sign is swapped
2a.) I've already explained how to reflect something over the x axis
2b.) I've already explained how to reflect something over the y axis
3a.) ohio lies around (5,3) and montana is around (-5,6) so to get their just go up (or north?) three and reflect accross the y axis
4.) louisana is around (2,-3) and to rotate 90 degrees clockwise would make the coordinates (-3, -2) which puts you around Texas
5.) new york's coordinates are around (8,5) to go left 4 and down three puts you at (4,2) to reflect it over the x axis gives you the coordinates (4,-2) which is in alabama
6a.) south dakota is around (-2,5) and to reflect it over the x axis gives you (-2,-5) which is texas
6b.) To reflect (-2,-5) over the y axis gives you (2,-5) which is gives you the fourth quadrant
7.) Kansas is around (-1,2) and to reflect over the y-axis gives you (1,2) and to go 6 right and 2 up gives you (7,4)
8.) new hampshiere is around (9, 6) and to get to texas which is around (-1,-3) so let's flip accross the x and y axis to get (-9,-6), then go 8 right and up 3
9.) idaho is around (-8,5) and to get 6 right gets you (-2,2) and to reflect over the y axis gives us (2,2) which is missouri and to get to ohio would require us to to get to (5,3) which would require us to go up 1 and right 3
10.) mississippi is around (3,-2) and to rotate 90 degrees clockwise puts us at (-2,-3) or (y,-x) which is quadrant 3
bonus.) north carolina is around (7,1), to reflect over the y axis puts us at (-7,1), to go up 5 and 4 right puts us at (-2,5) and to rotate 180 degrees clockwise gives us (2,-5)

Which function is quadratic?
A {=5.3), (-2.0), (1, 3). (4. 6))
B {(-2, 12), (0.2), (2.-8). (4, -18)}
C {(0, -126), (4, -14), (8, 2).(12,18)
D {(0, -10), (1.-7), (2, 2), (3. 17)}
Answer:
step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)
step 2. so the question becomes is C a quadratic
step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4
step 4. write out the y values: -126, -14, 2, 18
step 5. write out the differences: 140, 16, 16
step 6. write out the differences: -124, 0.
step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't
step 8. C is not a quadratic.

If using the method of completing the square to solve the quadratic equation x^2-5x-19=0x, which number would have to be added to "complete the square"?
Answer:
25/4 or 6.25
Step-by-step explanation:
Given that the general equation of a quadratic equation is given as
ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.
Hence given x^2-5x-19=0, to complete the square, we add
(-5/2)^2 to both sides following the illustration given.
This is 25/4 or 6.24

The solution of (10 x/6)(10 x/8) = 1010 is
The solution to the exponential expression is given as follows:
x = 34.29.
How to solve the exponential expression?
The exponential expression for this problem is defined as follows:
[tex]10^{\frac{x}{6}} \times 10^{\frac{x}{8}} = 10^{10}[/tex]
When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents.
The sum of the exponents is given as follows:
x/6 + x/8 = 4x/24 + 3x/24 = 7x/24.
Hence the equivalent expression is given as follows:
[tex]10^{\frac{7x}{24}} = 10^{10}[/tex]
The function 10^x is an injective function, hence the value of x is obtained as follows:
7x/24 = 10
7x = 240
x = 240/7
x = 34.29.

The quadratic function f is represented by the equation:
f(x)=(x - 4)^2 - 4
The table gives some of the values of the quadratic function g:
Which statement below is true?
a. the y-intercept of f(x) is greater than the y-intercept of g(x)
b.The y-intercept of g(x) is greater than the y-intercept of f(x)
c.The y-coordinate of the vertex of f(x) s greater than the y-coordinate of the vertex of g(x)
d.The x-coordinate of the vertex of g(x) is greater than the x-coordinate of the vertex of f(x)
Answer:
a. the y-intercept of f(x) is greater than the y-intercept of g(x)Step-by-step explanation:
Given function:
f(x)=(x - 4)^2 - 4We can work out the function from the table values:
g(x) = (x + 2)^2 - 4Options:
a. the y-intercept of f(x) is greater than the y-intercept of g(x)
True. x= 0 ⇒ f(0) = (-4)^2 - 4 = 12, g(0) = 2^2 - 4 = 0b. The y-intercept of g(x) is greater than the y-intercept of f(x)
False. See previous option.c. The y-coordinate of the vertex of f(x) s greater than the y-coordinate of the vertex of g(x)
False. They are same = -4d. The x-coordinate of the vertex of g(x) is greater than the x-coordinate of the vertex of f(x)
