hi please help with my maths!

 v= (4/3)* pi *(d/2)^3  =  (4/3) * pi  * (3/2)^3  = about 14.14 cu ft Hope this helps you

Answer:

14.13

Step-by-step explanation:

[tex] v = \frac{4}{3} \pi \: {r}^{3} [/tex]

v=4/3×3.14×1.5^3

v=4/3×3.14×3.375

use calculator

v=14.13 feet^3

Answer:

r ≥ -49/11

Simplified versions: r ≥ -4.45 or r ≥ -4 5/11

Answer:  [tex]r \ge -\frac{49}{11}[/tex]

r is greater than or equal to the fraction -49/11

==========================================================

Work Shown:

[tex]r + 5(-2r-10) \le -4r - 1 + 6r\\\\r - 10r - 50 \le -4r - 1 + 6r\\\\-9r - 50 \le 2r - 1\\\\-9r-2r \le - 1 + 50\\\\-11r \le 49\\\\r \ge \frac{49}{-11}\\\\r \ge -\frac{49}{11}\\\\[/tex]

Note how the inequality sign flips. This happens any time you divide both sides by a negative number.

Answer:

32

Step-by-step explanation:

Substitute a = - 2 into the expression and evaluate

3(- 2)² - 7(- 2) + 6 = 3(4) + 14 + 6 = 12 + 14 + 6 = 32

Answer:

32

Step-by-step explanation:

a^2=4

3*4=12

3a^2=12

7a= -14

-7a=14

6=6

12+14+6=32

Answer:

Step-by-step explanation: he standard form to find the value of X in multiplication operation is. Divisor × Dividend = Product. Let us take dividend = x, Divisor × x = Product. Then the formula to find the value of x is. X = product / Divisor

Answer:

x = 99

Step-by-step explanation:

4 sided polygon = 360 degrees

92 + 68 + 101 + x = 360

261 + x = 360

-261        -261

x = 99

Hope this helped! Have a nice day! Plz mark as brainliest!!!

Answer: THE ANSWER IS D. $2.15; $2.83

a taxi company charges passengers 1.75 for a ride,?

a taxi company charges passengers 1.75 for a ride, no matter long the ride is, and an additonal $0.40 for each mile traveled. the rule c=0.40m+1.75 describes the relationship between the number of miles M and the total cost of the ride c.  

what is the charge for 2.7 mile ride

A.    5.13

B.    1.08

C.    2.15

D.    2.83

Favorite Answer

D  2.83

c = 0.4. * 2.7 + 1.75

=> c = 2.83

Step-by-step explanation: It Looks Like The Answer is D

c=0.40(2.7)+1.75=$2.83 so $2.83 is the answer

1.75+(2.7*.4)=

1.75+1.08=

2.83

The answer is $2.83

Answer:

2x+20

Step-by-step explanation:

Given

Age of Ethen = x

If Raj is 8 years older than Ethen, then;

Raj = x + 8

6 years time

Ethen age = x+ 6

Raj = x+8+6 = x+14

Sum of ages in 6 years time = x+6+x+14

Sum of ages in 6 years time = 2x + 20

Hence the required sum of ages is 2x+20

Answer: -1

The answer is 37 I tried it and its right

Answer:

Step-by-step explanation:

The answer choices don’t make sense. The volume of a cylinder of height 45mm and radius 5mm = π5²*45 = 1125π mm³.

Three of the answer choices are larger than 1125π.

:::::

volume of one cone = πr²h* ⅓

Volume of cylinder section = πr²h

Total volume = πr²h*⅔ + πr²h = πr²h*5/3 = π5²*15*5/3 = 625π

Answer:

CD = 45

Step-by-step explanation:

CE = 180

( x + 6 ) + ( 4x - 21 ) = 180

5x - 15 = 180

5x = 195

x = 39

substitute x in CD

CD = x + 6

CD = 39 + 6

CD = 45

Answer:

168 square feet

Step-by-step explanation:

A = 18 x 8 + 8 x 6 x 1/2

A = 144 + 24

A = 168

Answer:

Step-by-step explanation:

Write in y = mx + b form

here, b ----> y intercept

2y - 2x = 8

     2y = 2x + 8         {Divide the equation by 2}

       [tex]\frac{2y}{2}=\frac{2x}{2}+\frac{8}{2}\\[/tex]

        y = x + 4

y-intercept = 4
