2.4z+1.2z-6.5=0.7 I don't get it

Answers

Answer 1

Answer: Basically that answer is incorrect. If you'd learn about combining, multiplying, dividing or subtracting like terms, this will be a simple problem. To be specific, like term is a number with a letter with it.

For example, 2.4z is a like term.

so you can only add like term, not any other normal number. When two terms have the same "letter", you will have to do what the sign said so in the problem....

2.4z + 1.2z - 6.5 = 0.7
3.6z - 6.5 = 0.7 (Add but leave the z alone because you are not multiplying)

The final answer is 3.6z - 6.5 because you cannot do anything else to that problem.

3.6z-6.5=0.7 is not true.

3 ( 4d + 1 ) - 9d = 6 - 2d

Answers

3(4d+1)-9d=6-2d
12d+3-9d=6-2d
3d+3=6-2d
5d=3 /:5
d=3/5

Answer:

d=3/5

Step-by-step explanation:

3 ( 4d + 1 ) - 9d = 6 - 2d

12d + 3 - 9d = 6 - 2d

12d - 9d + 2d = 6 - 3

5d = 3

d = 3/5

d = 0.6

How mAny full10ozportions can be obtained from 14ld of trimmed meat

Answers

You would have 22 full 10oz portions.

First you have to multiply 16 by 14, because there are 16oz in one pound and there is 14 pounds. You do this to convert it into ounces. When you do this you get 224.

Now you have to divide it by 10, because you want to find out how many portions you can have. When you do this you get 22 portions. There will be 4oz left over.

The sector shows the area of a lawn that will be watered by a sprinkler. What is the area, rounded to the nearest tenth? Use 3.14 for

Answers

The area of the sector which representsthe lawn irrigated by the sprinkler is: $\mathbf{ 95.5 $ ft^2}$

Recall:

Area of sector = $(\theta)/(360) * \pi r^2$

Length of arc = $(\theta)/(360) * 2 \pi r$

Given:

$\theta = 30^(\circ)$

length of arc = 10 feet

First, find the radius using the length of arc formula.

$(\theta)/(360) * 2 \pi r$

Substitute

$10 = (30)/(360) * 2 * 3.14 * r\n\n10 = 0.52r\n\nr = (10)/(0.52) \n\nr = 19.2$

radius = 19.2 ft

Find the area of the sector:

Area of sector = $(\theta)/(360) * \pi r^2$

Substitute

$= (30)/(360) * * 3.14 * 19.2^2\n\n\mathbf{= 95.5 $ ft^2}$

The area of the sector which representsthe lawn irrigated by the sprinkler is: $\mathbf{ 95.5 $ ft^2}$

Answer:

$95.5\ ft^2$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

A circumference of the circle subtends a central angle of 360 degrees

using proportion

$(2\pi r )/(360^o)=(10)/(30^o) \n\nr=(360(10))/(2(3.14)(30))\n\nr= 19.1\ ft$

step 2

Find the area of sector

we know that

The area of the circle subtends a central angle of 360 degrees

so using proportion

Let

x ----> the area of the sector

$(\pi r^(2))/(360^o)=(x)/(30^o)\n\nx=(3.14(19.1^2)(30))/(360)\n\nx=95.5\ ft^2$

clara compro 3/4 de kilo de manzanas, una libra de peras y determinada cantidad de durasnos.si el peso total de la fruta fue 3 3/4 kilos cuantos kilos de durazno compro clara

Answers

esto te ayudaria es el primero

Final answer:

Para encontrar cuántos kilos de durazno compró Clara, debemos restar el peso de las manzanas y peras del peso total de la fruta que compró. Esto nos da que Clara compró 2.55 kilos de durazno.

Explanation:

Para calcular cuántos kilos de durazno compró Clara, primero debemos saber la cantidad de frutas que ya ha comprado. Sabemos que Clara compró 3/4 de kilo de manzanas y una libra de peras. En muchos lugares, una libra se considera 0,45 kilos, por lo que 1 libra de peras equivale a 0,45 kilos. Entonces sumamos estas dos cantidades, lo que equivale a 1.2 kilos (3/4 kilos + 0,45 kilos).

Ahora, si restamos este total (1.2 kilos) del peso total de la fruta que Clara compró (3 3/4 kilos o, lo que es lo mismo, 3.75 kilos), obtendremos el peso de los duraznos que compró Clara. Por lo tanto, 3.75 kilos - 1.2 kilos nos da 2.55 kilos.

Por lo tanto, Clara compró 2.55 kilos de durazno.
