Three faces of a rectangular prism have areas 32 cm?, 40 cm?, and 20 cm? a) find the surface area of the prism. b) what are possible dimensions of the prism? how do you know? c) sketch and label the prism.
Answer:
Surface Area: 5440
Step-by-step explanation:
Volume: 25600
Surface Area: 5440
Work Volume
V = lwh
V = (32)(40)(20)
V = 25600
Work Surface Area
A = 2(wh + lw + lh)
A = 2( 40(20) + 32(40) + 32(20) )
A = 2(800 + 1280 + 640)
A = 2(2720)
A = 5440
The diagonal : 54.99
darlene can finish an average-sized crocheted centerpiece for 2 week how many days will it take her to finish 4 projects?
Given that, Darlene can finish an average-sized crocheted centerpiece for 2 week, the number of days it will take her to finish 4 projects is 56 days.
How many days will it take Darlene to finish 4 projects?
Given that;
Darlene can finish an average-sized crocheted centerpiece in 2 week = ( 2 × 7)days = 14 dayshow many days will it take her to finish 4 projects?If 1 project takes 14 days
4 project takes x days
x = 4 × 14 days
x = 56 days
Given that, Darlene can finish an average-sized crocheted centerpiece for 2 week, the number of days it will take her to finish 4 projects is 56 days.

a punch recipe calls for 1 liter of lemon soda for every 3 liters of fruit juice. If a woman uses 10 liters of fruit juice how many liters of lemon soda does she need
Answer: 3 [tex]\frac{1}{3}[/tex] liters
Step-by-step explanation:
We will set up a proportion to help us solve.
[tex]\displaystyle \frac{10 \text{ liters of fruit juice}}{x\text{ liters of lemon soda}} =\frac{3 \text{ liters of fruit juice}}{1\text{ liters of lemon soda}}[/tex]
Now we will cross multiply.
10 = 3x
Lastly, we will divide both sides by 3.
3 [tex]\frac{1}{3}[/tex] = x
She will need 3 [tex]\frac{1}{3}[/tex] liters of lemon soda.

Answer:
[tex]\frac{6}{k-6}[/tex]
Step-by-step explanation:
First, we can factor all of the following equations to turn that weird, huge looking thing into [tex]\frac{(k+6)(k-6)}{(k-6)(k-10)}[/tex] ÷ [tex]\frac{(k-6)^2}{k(k-6)}[/tex] × [tex]\frac{6(k-10)}{k(k + 6)}[/tex]. We know that division is simply multiplication by the reciprocal, so that whole equation will turn into [tex]\frac{(k+6)(k-6)}{(k-6)(k-10)}[/tex] × [tex]\frac{k(k-6)}{(k-6)^2}[/tex] × [tex]\frac{6(k-10)}{k(k+6)}[/tex]. Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into [tex]\frac{6}{k-6}[/tex] which is our final answer, as it cannot be simplified further.
Hope this helped! :)

Two paper cones are mathematically similar. The capacity of the larger cone is 8 times the capacity of the smaller cone. The surface area of the smaller cone is 50 cm². Find the surface area of the larger cone.
Answer:
200 cm²
Step-by-step explanation:
The scale factor for areas of similar figures is the square of the scale factor relating their linear dimensions. For volumes of similar figures, the scale factor is the cube of the linear dimension scale factor. Together, these relations mean the area scale factor is the 2/3 power of the area scale factor.
__
The larger surface area is ...
(50 cm²) × 8^(2/3) = (50 cm²) ×4 = 200 cm²
_____
Additional comment
The linear dimension scale factor is the cube root, or 1/3 power, of the volume scale factor. The area scale factor is the square of that or the 1/3 power times 2, the 2/3 power.
sf = ∛(v2/v1) = (v2/v1)^(1/3)

a knife is four times the cost of a spoon. 12 spoons and 16 knives cost £105.64. work out the cost of 1 knife
Answer:
£5.56Step-by-step explanation:
let K be the cost of a knife
S Ben the cost of a spoon
The statement “a knife is four times the cost of a spoon”
means K = 4S
means S = (1÷4)K
the statement “12 spoons and 16 knives cost £105.64”
means 12S + 16K = 105.64
⇔ 12(1÷4)K + 16K = 105.64
⇔ 3K + 16K = 105.64
⇔ 19K = 105.64
⇔ K = 105,64÷19
= £5.56

Theo, Nancy, and Mary each drove separately to meet at their grandmother’s house for dinner. Theo drove 50 miles, Nancy drove √2,840 miles, and Mary’s route is shown below.
A right triangle with side lengths 48 miles and 13 miles. The hypotenuse is labeled Mary's Route.
Approximately how many miles did Mary drive to her grandmother’s house?
Order the distances that each family member drove to their grandmother’s house from least to greatest.
Answer:
Mary's route = 49.73 miles
Step-by-step explanation:
[tex] {r}^{2} = {x}^{2} + {y}^{2} [/tex]
[tex]r = \sqrt{ {x}^{2} + {y}^{2} } [/tex]
[tex]r = \sqrt{ {48}^{2} + {13}^{2} } [/tex]
[tex]r = \sqrt{2473} [/tex]
[tex]r = 49.73 \: miles[/tex]
[tex] \sqrt{2840} = 53.3 \: miles[/tex]
Arranging the distances from least to greatest:#1: Mary's route = 49.73 miles
#2: Theo's route = 50 miles
#3: Nancy's route = 53.3 miles
Answer:
first is 49. 73; second Mary, Theo, Nancy

-1/2
Step-by-step explanation:
To findSlope
Given[tex] \sf let \: ( - 9, - 5) = (x_1,y_1) \\ \\ \sf ( - 1, - 9) = (x_2,y_2)[/tex]
Solution[tex] \sf Slope(m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Substituting the values
[tex] \sf \implies m = \frac{ - 9 - ( - 5)}{ - 1 - ( - 9)} \\ \\ \\ \sf \implies m = \frac{ - 9 + 5}{ - 1 + 9} \\ \\ \\ \sf \implies m = \frac{ - 4}{8} \\ \\ \\ \sf \implies m = - \frac{1}{2} [/tex]

What is the congruence theorem?Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.
Consider ΔABC and ΔDEF,
Here, ∠B=∠E=50°
AB=DE=10 units
With ∠C=∠F
So, by AAS congruence theorem ΔABC and ΔDEF are congruent
Therefore, option A is the correct answer.

What is the volume of this sphere?
Use A 2 3.14 and round your answer to the nearest hundredth.
Answer:
hope this will help you ( ◜‿◝ )♡
Step-by-step explanation:
[tex]volume = \frac{4}{3} \times \pi {r}^{3} \\ = \frac{4}{3} \times 3.14 \times ( {10}^{3} ) \\ = 4186.666mm {}^{3} [/tex]
[tex]\large\boxed{\bold{Formula:V= \frac{4}{3}\pi{r}^{3}}}[/tex]
[tex]\large\boxed{\bold{\red\pi\red=\red3\red.\red1\red4}}[/tex]
In this question the radius is given so we'll simply have to substitute and solve.
Let's solve!
Instead of π we are asked to use 3.14
Substitute the values according to the formula.
[tex]V= \frac{4}{3}\times 3.14 \times {10}^{3}[/tex]
Calculator value:
[tex]\bold{V= 4186.666667 \: {mm}^{3}}[/tex]
Now, we have to round off to the nearest hundredth.
The value in the thousandths place is greater than 5 so we'll have to round up by adding 1 to the hundredths place.
Final answer:
[tex]\large\boxed{\bold{V= 4186.67 \: {mm}^{3}}}[/tex]
Hence, the volume of the given sphere is 4186.67 cubic millimeters.
