The ratio of a basketball player's completed free throws to attempted free throws is 4 to 7. If she completed 12 free throws, find how many free throws she attempted.
a. 3 free throws
b. 7 free throws
c. 21 free throws
d. 4 free throws
Answer:
well for Evey 4 completed throws she takes 7 throws
with this ratio we get that;
it's 4:7
there fore
for 12 completed free throws she would take 21 free throws
option c is the answer
hope it's helpful
Answer:
21
Step-by-step explanation:
FreeThrows: FT
Attempted Throws: AT
FT/AT=4/7
12/AT=4/7
84/4=AT
AT=21

is fraction a linear equation
Answer:
NO
Step-by-step explanation:
We need more than two operations to solve a linear equation . If an equation contains fractions, multiply both sides of the equation by the least common denominator (LCD) to clear fractions.
Please help ASAP and explain the answer, thank you
Answer:
Step-by-step explanation:
1) x² - 8x + 5 = 0
2) No subtract 5 from both sides
x² - 8x + 5 - 5 = 0 - 5
x² - 8x = -5
3) Now find (8/2) = 4. Add 4² = 16 to both sides
x² - 8x + 16 = -5 + 16
x² - 8x + 16 = 11
4) (x - 4)² = 11
5) Take square root both sides
x - 4 = ±√11
x = 4 ±√11

We know that, Two angles are said to be complementary, if the sum of their measures is 90°.
According to the Question,
⇒ ∠ABD + ∠DBC = 90°
⇒ (2x + 30)° + (3x + 20)° = 90°
⇒ 2x + 30° + 3x + 20° = 90°
⇒ 5x + 50° = 90°
⇒ 5x = 90° - 50°
⇒ 5x = 40°
⇒ x = 40°/5
⇒ x = 8
So, the measure of each angle will be,
⇒ ∠ABD = (2x + 30)°
= 2 × 8 + 30°
= 16 + 30°
= 46°
⇒ ∠DBC = (3x + 20)°
= 3 × 8 + 30°
= 24 + 30°
= 54° ▄▄▄▄▄▄▄▄▄▄▄▄▄▄A clothing store is having a sale on socks each pair of sock are $3 if the store sells 407 pairs of socks how much money will they make

S(-4, -6) and T(-7, -3); Find R.
Answer:
(13,-6)
Step-by-step explanation:
The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.
First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.
Then do the same thing with the y coordinate. And you get -6.
Your endpoint is (13,-6)
Find the distance along an arc on the surface of the earth that subtends a central angle of 1 minute(s) (1 minute = 1/60 degree). The radius of the earth is 3960 miles. Round to the thousandths. (3 decimal places)
Length of distance of arc = 2πr × (∅/360)
∅ = 1/60 × 360 = 6⁰
Length = 2 × 22/7 × 3960(6/60)
Length = 44/7 × 3960 × 1/10
Length = 44/7 × 396
Length = 2489.142 cm

find the measure of the angle that is 12° more than two times its supplement
Answer:
56 and 124
Step-by-step explanation:
Sum of two supplementary angle = 180
Let the first angle be x
Second angle = 2x + 12
2x + 12 + x = 180
3x + 12 = 180
3x = 180 - 12
3x = 168
x = 168/3
x = 56
2x + 12
2(56) + 12
112 + 12
124

Profit is always calculated as revenue minus expenses. If a company's expenses were $10 million, write an equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars). Then, determine the profit when revenue is $25 million.
a. P= 10-R; $15 million
b. P=R-10; $15 million
c. P=R-10; $35 million
d. P=10-R$35 million
Please select the best answer from the choices provided
Answer: B
Step-by-step explanation:
P=R-$10MM
P = ($25MM)-$10MM
P = $15MM
How would I plot and label the numbers 6.5 & 8.5 on a number line to write a inequality using the symbol “>” to compare the two numbers
Answer:
To label 6.5 on a number line, put the plot between the 6 and 7.
Same thing goes for 8.5, except the plot would go between the 8 and 9.
8.5 > 6.5
Step-by-step explanation:
1.) Since 8.5 and 6.5 are decimals, they are not a whole number which is why they go right in the middle of the two numbers they are behind and in front of.
2.) > means greater than, and 6.5 is smaller than 8.5 therefore we use the greater than sign, pointed towards the 8.5.

(A) Two acute angles add to an obtuse angle
(B) Two adjacent angles make a line
(C)Two obtuse angles are supplementary
Decide if each statement is always, sometimes, or never true.
I said never for the first one I’m new to geometry and I’m a freshman I’m taking notes along the way so whatever information you have for me will help!❤️
Answer:
(A) Two acute angles add to an obtuse angle
It's sometimes because for example if you take two acute angles
one is 30 and other is 20
they add to 50 and not greater than 90 so it can be sometimes greater but not always
(B) Two adjacent angles make a line
Its also sometimes because a line means it should be 180 degrees so two adjacent angles can out always be equal to 180 that is a line
(C)Two obtuse angles are supplementary
It's Never true because obtuse angles start from 90 so if you take 91 also and other 91 too so if we add them up that will be 182 not 180
as we know 180 = supplementary angle that's why

[tex]\text{Suppose the width of the rectangle is }x\text{ cm}[/tex]
[tex]\text{then the perimeter can be expressed as}[/tex]
[tex]2(24+x)=72[/tex]
[tex]24+x=36[/tex]
[tex]x=12[/tex]
[tex]\text{Therefore the area of the rectangle is }24\cdot x=24\cdot 12=288\text{ cm}{}^2[/tex]
Answer: Solution,
length (l) = 24 cm
perimeter (p)= 74 cm
Area (A) = ?
we know,
P = 2(l + b )
74 = 2( 24 + b)
74 = 48 + 2b
2b = 74 - 48
2b = 26
b= [tex]\frac{26}{2}[/tex]
b = 13
now,
A = l*b
= 24 * 13
