1 ) Old Navy is offering a 20 % discount on all sweaters. If the regular price of a sweater is $45,what is the sale price?
Answer:
Sale Price = $36
Step-by-step explanation:
To find the sale price, you need to find what 10% of the original price is. 10% of $45 is $4.50. Now we need to find what 20% is, 20% is double 10% so we multiply the answer we got by 2. This equals to $9. The question is asking for the sale price, to find it you have to subtract $9 (the discount) from $45 (regular price). The answer you should get is $36.
Equation:
$45 ÷ 10 = $4.50
$4.50 × 2 = $9
$45 - $9 = $36

• A. 96r units3
•
B. 2257 units*
• C. 1927 units3
D. 5767 units3
Answer:
192π
Step-by-step explanation:
cylinder volume is base times height
2πr^2 = base = 64π
height = 3
64π*3 = 192π
The volume of the given cylinder is 192π cubic units. Therefore, option C is the correct answer.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
From the given figure, radius of a cylinder = 8 units and radius of a cylinder = 3 units.
We know that, volume of a cylinder is πr²h.
Now, volume = π×8²×3
= π×64×3
= 192π cubic units.
Therefore, option C is the correct answer.

Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89

find the vol of this prism
Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A = [tex]\frac{1}{2}[/tex] bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A = [tex]\frac{1}{2}[/tex] × 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³

The area of a circle is 36.43cm2.
Find the length of the radius rounded to 2 DP.
Answer:
3.40 cmStep-by-step explanation:
It is given that the area of a circle is 36.43cm² and we have to find the length of the radius.
So, first of we must know this formula :
⇒ πr² = Area(Circle)
We will take the value of π as 3.14Now, Substituting the given values in the formula :
⇒ 3.14 × r² = 36.43
⇒ r² = 36.43/3.14
⇒ r² = 11.60
⇒ r = √11.60
⇒ r = 3.40
Therefore,
The radius of the circle is 3.40 cmHey ! there
Answer:
Radius of circle = 3.40 cmStep-by-step explanation:
In this question we are given with area of circle that is 36.43 cm² . And we are asked to find the length of radius of circle rounded to two decimal points .
We know that ,
[tex] \qquad \quad \frak{Area_{(Circle)} = \pi r {}^{2} } \quad \bigstar[/tex]
Where ,
π = 3.14r = radius of circleSolution : -
According to question , area of Circle is equal to 36.43 . So ,
[tex] \longrightarrow \qquad \: \pi r {}^{2} = 36.43[/tex]
Step 1 : Substituting value of π :
[tex] \longrightarrow \qquad \:3.14 \times r {}^{2} = 36.43[/tex]
Step 2 : Transposing 3.14 to right side :
[tex] \longrightarrow \qquad \: r {}^{2} = \cancel{\dfrac{36.43}{3.14} }[/tex]
On dividing 36.43 by 3.14 , We get :
[tex] \longrightarrow \qquad \: r {}^{2} = 11.60[/tex]
Step 3 : For removing square from r , We are applying root on both sides :
[tex] \longrightarrow \qquad \: \sqrt{r {}^{ 2 }} = \sqrt{ 11.60}[/tex]
We get :
[tex] \longrightarrow \qquad \:r = \sqrt{11.60} [/tex]
Step 4 : Finding square root of 11.60 , We get :
[tex] \longrightarrow \qquad \: \purple{\underline{\boxed{\frak{r = 3.40 \: cm}}}} [/tex]
Therefore, radius of circle is 3.40 cm#Keep LearningWhat is the solution of log subscript 3 baseline (3 x 2) = log subscript 3 baseline (4 x minus 6)?

What is 4,255 rounded to the nearest THOUSAND?
Answer:
4,000
Step-by-step explanation:
To round a number, take the place next to the one you wish to round and look to see if it is four or under, or five or up. In this case, 2 is less than 5 so we will be rounding down towards the nearest integer, which is 4. Also, all places after the place value you round will become zero. So, 4,000 rounded to the thousands place is 4,000.
