In the figure, the measure of angle 9 is 80 degrees and the measure of angle 5 is 68. Find the measure of each angle.
Answer/Step-by-step explanation:
Given:
m<9 = 80°,
m<5 = 68°
Lines w and v are parallel to each other.
m<1 = m<9 (corresponding angles theorem)
m<1 = 80°
m<2 + m<1 = 180° (linear pair)
m<2 + 80° = 180° (substitution)
m<2 = 180° - 80°
m<2 = 100°
m<3 = m<1 (vertical angles are congruent)
m<3 = 80°
m<4 = m<2 (vertical angles are congruent)
m<4 = 100°
m<6 + m<5 = 180° (linear pair)
m<6 + 68° = 180° (substitution)
m<6 = 180° - 68°
m<6 = 112°
m<7 = m<5 (vertical angles)
m<7 = 68°
m<8 = m<6 (vertical angles)
m<8 = 112°
m<10 = m<2 (corresponding angles)
m<10 = 100°
m<11 = m<9 (vertical angles)
m<7 = 80°
m<12 = m<10 (vertical angles)
m<12 = 100°
m<13 = m<5 (corresponding angles)
m<13 = 68°
m<14 = m<6 (corresponding angles)
m<14 = 112°
m<15 = m<13 (vertical angles)
m<15 = 68°
m<16 = m<14 (vertical angles)
m<16 = 112°

To prepare for a bake-off, Dan used 0.68 kilogram of flour each day for 4 weeks. How many grams did Dan use in those 4 weeks? (1 kg = 1,000 g) this question is from Zearn and I've been doing the same one for a week now :3 and no im not in highschool it put that for some reason
Answer:
19040 grams
Step-by-step explanation:
Dan used the amount of flour each day = 0.68 kg
He used the flour for 4 weeks.
So the number of days taken by Dan = 4 × 7 = 28 days
Now amount of flour used in 28 days = Flour used in a day × Number of days
= 0.68 × 28
= 19.04 kg
Since 1 kg = 1000 grams
Therefore, 19.04 kg = 1000 × 19.04 = 19040 grams
Dan used 19040 grams of flour in 4 weeks.
The number of grams of flour that was used is 19040 grams.
Since Dan used 0.68 kilogram of flour each day for 4 weeks, this means that the flours used will be:
= 0.68 × 4
= 2.72kg
Therefore, 2.72kg will be converted to grams and this will be:
= 2.72 × 1000 = 2720 grams
Now, we'll multiply the value by 7 since there are 7 days in a week. This will be:
= 2720 × 7 = 19040

How can I describe a ordered pair
Answer:
Ordered Pair An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.
Step-by-step explanation:
i hope this helped! :)
Answer:
An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

if f(x) = x^3+2x^2-5, then what is f(-3)
Answer:
f(- 3) = - 14
Step-by-step explanation:
To evaluate f(- 3) substitute x = - 3 into f(x), that is
f(- 3) = (- 3)³ + 2(- 3)² - 5 = - 27 + 2(9) - 5 = 27 + 18 - 5 = - 14
How do you write 2x^5-9x^4-2x^2+10 in standard form?
Answer:
[tex]2x^5-9x^4+0x^3-2x^2+0x+10[/tex]
Step-by-step explanation:
A polynomial is in standard form when its terms are ordered from highest to lowest degree.
If the polynomial is missing terms, it must be completed by setting their coefficients to 0.
The given polynomial is:
[tex]2x^5-9x^4-2x^2+10[/tex]
The terms are ordered, but it's incomplete. The terms with exponent 3 and 1 must be included with zero coefficient.
Thus the polynomial in standard form is:
[tex]\boxed{2x^5-9x^4+0x^3-2x^2+0x+10}[/tex]

Find the two integers, m and n,
make the equation (2x^ny2)m = 4x6y4 true.
Answer:
m = 2 and n = 3
Step-by-step explanation:
We want to find the value of the integers m and n that will make the given expression true
(2x^ny^2)^m = 4x^6y^4
We can rewrite the left hand side of the equation as follows;
(2x^3y^2)^2
we can proceed to use inspection to ind the value of m and n
Through inspection since the left hand side of the equation now looks like the right hand side;
Then;
m= 2 and n = 3
