Answer:
38+?=111
DCB=111-38
DCB=73
Answer:
73°
here's your solution
=> angle D + angle C = angle CBQ
=> Because we know that exterior angle
equal to sum of two opposite interior angles
=> D +C = CBQ
=> C + 38° = 111°
=> C = 111 - 38
=>. C = 73°
hope it helps

Given:
The expression is

To find:
The simplified form of the expression.
Solution:
We have,
[tex]\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=[/tex]
The expression [tex]\sqrt[3]{48}[/tex] can be written as
[tex]\sqrt[3]{48}=\sqrt[3]{8\cdot 6}[/tex]
[tex]\sqrt[3]{48}=\sqrt[3]{8}\cdot \sqrt[3]{6}[/tex] [tex][\because \sqrt[3]{ab}=\sqrt[3]{a}\sqrt[3]{b}][/tex]
[tex]\sqrt[3]{48}=2\cdot \sqrt[3]{6}[/tex]
[tex]\sqrt[3]{48}=2\sqrt[3]{6}[/tex]
Therefore, [tex]\sqrt[3]{48}=\sqrt[3]{8\cdot 6}=2\sqrt[3]{6}[/tex].
Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?
Answers
Answer: The girls walked [tex]1\dfrac38[/tex] miles.
Step-by-step explanation:
Given: Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile
Distance from school to store = [tex]\dfrac38[/tex] mile
Distance from store to home = [tex]\dfrac25[/tex] miles
Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]
= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex] [L.C.M.(10,8,5)=40]
= [tex]\dfrac{24+15+16}{40}[/tex]
= [tex]\dfrac{55}{40}[/tex]
= [tex]\dfrac{11}{8}=1\dfrac38[/tex] miles
Hence, The girls walked [tex]1\dfrac38[/tex] miles.
A triangle is formed by first plotting a point at (3, 4) on the coordinate plane. The second point is a reflection of the first across the x-axis.

Bella's Bakery charges $2.25 per cupcake
and $1.75 per cookie. A customer came in
and ordered 5 cupcakes, some cookies,
another cupc
e and paid $24. Write and
solve an equation to determine how many
cookies they purchased.
Answers
Answer:
6 cookies
Step-by-step explanation:
first, find how much money they spent on cupcakes
6 × $2.25 = $13.5
then, take $13.5 and subtract that by $24
$24 - $13.5 = $10.5
so the person spent $10.5 on cookies. divide the amount per cookie by $10.5
$10.5 ÷ $1.75 = 6
so they bought 6 cookies

(calculation attached)

i hope im right!
The shortest length of the wood will be 24 meters.
What is the least common factor?
The Least Common Multiple (LCM) refers to the common multiple that is the least (smallest) among all possible multiples for both numbers. Calculating this least common multiple for numbers is made easier by the LCM formula.
Given that the length of the wood is 3m, 8m, and 12 m. The shortest length will be calculated by taking the least common factor of the given lengths 3m, 8m, and 12 m.
The least common factor is calculated as:-
3 = 3 x 1
8 = 2 x 2 x 2
12 = 2 x 2 x 3
LCM = 3 x 2 x 2 x 2 = 24
Hence, the shortest length of the wood will be 24 meters.

Find the slope of the line parallel to the line passing through the given points: (-2, 8) and (-6, 6)

Step-by-step explanation:
Use the points to find the slope, using the formula (y2 - y1) / (x2 - x1).

Since it's just asking for the slope, the answer is 2 (any parallel lines have the same slope).
