can y’all help me I know it’s easy but still 2×5.6÷2.8+3.5

Answer:

363-138=-5x

Step-by-step explanation:

Let c = cost

We know that the total cost is $363:

363-??????

We also know that he spent $138 on parts:

363-138?????

And we are solving for the cost of labor per hour:

363-138=5x

We can use this equation to find the total cost of labor per hour.

Hence, your equation will be 363-138=5x

To get the rectangle, multiply 10*3 = 30

Then to find both triangles, multiply 10*5=50

30+50=80

Let me know if this helped <3

Answer:

130 ft.

Step-by-step explanation:

the rectangle area is 30, cause l×h = area

triangle area is b×h and theres two so 5 x10 = 50 then multiply by 2 again so 100

then add both sums: 100+30 equalsssss 130.

The total volume of the silo is 116.6 m³.

It is a solid where a hemisphere is kept on top of a cylinder sharing common circular bases.

Diameter of the cylinder of the silo= 4.4m

So, the radius r of the cylinder will be = 2.2m

The radius r of hemisphere = 2.2m (same as cylinder due to common circular bases)

Height h of the cylinder = 6.2m

The total volume of the silo will be the combined volume of the cylinder and hemisphere.

The volume of cylinder = [tex]\pi r^{2} h[/tex]

The volume of hemisphere = [tex]\frac{2}{3} \pi r^{3}[/tex]

Total volume = [tex]\pi r^{2} h+ \frac{2}{3} \pi r^{3}[/tex]

total volume = [tex]\pi r^{2} (h+\frac{2}{3} r)[/tex]

Total volume = [tex]\pi *2.2^{2} (6.2+\frac{2}{3} *2.2)[/tex]

Total volume = 116.6 m³.

Therefore, the total volume of the silo is 116.6 m³.

Hey there!

CHOICE A. j = 4

6j - 3

= 6(4) - 3

= 24 - 3

= 21

Thus, the answer is: 21

CHOICE B. b = 3

b(b) + 5

= 3(3) + 5

= 22

Thus, your answer is: 22

All you had to do was substitute the values of the letters into the equation to find your answer.

For 64 - 3 you have to START at 64 and go BACK 3 spaces DOWNWARD (also known as to the LEFT of the number line) and you should be STOPPED on 61. So, 64 - 3 would most likely be: 61

Step-by-step explanation:

Step-by-step explanation:

milliliters change to liters

So,Gracie's bottle hold is 0.65 liters

The factorized form of the polynomial 6x³ – 12x² + 7x – 14 is (6x²+7)(x–2).

A factor of n is a number which when multiplied by another number gives us the number n.

In order to factorize the polynomial 6x³ – 12x² + 7x – 14, we need to take the common terms out of the given polynomial, therefore, the polynomial can be factorized as,

[tex]6x^3-12x^2+7x - 14 \\\\[/tex]

Taking the common term 6x² out from the first two terms, and then 7 from the next two terms, therefore, the polynomial can be written as

[tex]6x^3-12x^2+7x - 14 \\\\= 6x^2(x-2)+7(x-2)\\\\=(6x^2 +7)(x-2)[/tex]

Hence, the factorized form of the polynomial 6x³ – 12x² + 7x – 14 is (6x²+7)(x–2).

The product of the provided binomial numbers (9 t minus 4)(negative 9 t minus 4) is equal to the option B which is,

[tex]-81t^2+16[/tex]

Product is the resultant number which is obtained by multiplying a number with another. Let a number a is multiplied by number b. Then the Product of these two number will be,

[tex]p=a\times b[/tex]

Here, (a, b) are the real numbers.

The binomial given in the problem are,

[tex](9t-4)\\(-9t-4)[/tex]

Let the product of the above function is p. Thus,

[tex]p=(9t-4)\times(-9t-4)[/tex]

To find the product of these two binomials, multiply the first term of first binomial with both the terms of the second binomial.

Similarly, multiply the second term of first binomial with both the terms of second binomial. Thus,

[tex]p=9t(-9t-4)-4(-9t-4)\\p=-81t^2-36t+36t+16\\p=-81t^2+16[/tex]

Thus, the product of the provided binomial numbers (9 t minus 4)(negative 9 t minus 4) is equal to the option B which is,

[tex]-81t^2+16[/tex]

Answer:

1.2

Step-by-step explanation:

How I would calculate it would be 10.80 divided by 9 or start timesing 1 with a decimal like 1.1 or 1.2.

but anyway 10.80 divided by 9=1.2 and if you just want to make sure then what is 1.2 x 9 it = 10.80

Here is my calculations for what is 1.20 x 9   

 1 . 20

       9

_________

 10   . 8 0  

Since there is no didget beside the 2 you would add a zero

since 9 x 2=18 you add a 1 for 1 x 9 =9 + 1=10 and there's your answer.

The volume of the cylindrical stylus having a conical tip will be V=14π [tex]cm^{3}[/tex]

It is given that

height of the cylindrical shape of the stylus h=13cm

radius of stylus r= 1cm

height of the conical tip of the stylus h=3cm

Now we know that the

The volume of the cylinder = [tex]\pi r^{2} h[/tex]

The volume of the cone =  [tex]\dfrac{1}{3} \pi r^{2} h[/tex]

The total volume of the stylus = volume of the cylinder +volume of the cone

Total volume = [tex]\pi r^{2} h + \fdrac{1}{3} \pi r^{2} h[/tex]

now by putting the values

[tex]=\pi (13)(1)^{2} +\dfrac{1}{3} \pi (1)^{2} (3)[/tex]
