basically you have to calculate the perimeter-

Step-by-step explanation:

4+4+0.8+0.8=8+1.6=9.6

First you need to find the parameter

P= (L x 2)+(W x 2)

P=(4km x 2)+(0.8km x 2)

P=8km+1.6km

P=9.6km

Yoko received a $90 gift card for a coffee store. She used it in buying some coffee that cost $8.23 per pound. After buying the

xeze [42]

Answer: 6

Step-by-step explanation:

Step 1: Set up equation:

90=40.62+8.23p

^ the 'p' represents pounds.

Step 2: Subtract 40.62 from both sides

49.38 = 8.23p

Step 3: Divide both sides by 8.23 (We do this to get the variable "p" by itself)

6=p

Calcula el radio de un cilindro que tiene 8 cm de altura y un volumen de 122 cm cúbicos

kondaur [170]

Answer:

$\huge{ \boxed{ \sf{2.20 \: cm}}}$

Step-by-step explanation:

$\star{ \sf{ \: altura \: de \: un \: cilindro\: = \: 8 \: cm}}$

$\star{ \sf{ \: volumen \: de \: un \: cilindro = 122 \: cm \: cúbicos}} \:$

$\star { \sf{ \: encontrar :radio \: de \: un \: cilindro }}$

$\boxed{ \sf{ \: Volume \: of \: a \: cylinder \: = \: {\pi \: radius}^{2} \: height}}$

$\mapsto{ \sf{122 \: = \: ( \frac{22}{7} )r \: ^{2} \: \times \: 8}}$

$\mapsto{ \sf{122 = 25.14 \: {r}^{2} }}$

$\mapsto{ \sf{25.14 \: {r}^{2} = 122 }}$

$\mapsto{ \sf{ \frac{25.14 \: {r}^{2} }{25.14} = \frac{122}{25.14}}}$

$\mapsto{ \sf{ {r}^{2} = 4.85 \: cm}}$

$\mapsto{ \sf{r = 2.20 \: cm}}$

radio de un cilindro = 2.20 cm

Tension needs to eat at least an extra 1,000 calories a day to prepare for running a marathon. He has only $25 to spend on the e

Elden [556K]

Answer:

Yes, he can buy 8 donuts and 4 energy drinks.

Step-by-step explanation:

If Tension is able to buy 8 donuts and 4 energy drinks, then both inequalities would be valid when we use these numbers as inputs. Let's check each expression at a time:

$0.75*d + 2*e \leq 25\\0.75*8 + 2*4 \leq 25\\6 + 8 \leq 25\\14 \leq 25$

The first one is valid, since 14 is less than 25. Let's check the second one.

$360*d + 110*e \geq 1000\\360*8 + 110*4 \geq 1000\\2880 + 440 \geq 1000\\3320 \geq 1000$

The second one is also valid.

Since both expressions are valid, Tension can buy 8 donuts and 4 energy drinks and achieve his goal of having a caloric surplus of at least 1000 cal.
