What us 1/10 of 3,000

Give the value of x for the equivalent ratio 3:8 x:24

soldier1979 [14.2K]

Answer:

9

Step-by-step explanation:

3/8=x/24 (cross multiplication)

3*24=8x (we don't need to multiply 3 with 24 bc we will divide both sides by 8 so it will be easier to find the final value)

x=9

50 POINTS 10 QUESTIONS! Solve each quadratic equation using factoring PLEASE HELP!!

Tanzania [10]

Answer:

Quadratic Equation | Factoring

Solve each quadratic equation using factoring.

1) v² + 5v + 6 = 0

doing middle term factorisation

v²+(3+2)v+6=0

v²+3v+2v+6=0

v(v+3)+2(v+3)=0

(v+3)(v+2)=0

either

v=-3

or

v=-2

2) g² - 3g = 4

keeping all terms in one side

g²-3g-4=0

doing middle term factorisation

g²-(4-1)g-4=0

g²-4g+g-4=0

g(g-4)+1(g-4)=0

(g-4)(g+1)=0

either

g=4

or

g=-1

3)w² + 4w = 0

w(w+4)=0

either

w=0

or

w=-4

4) s² - 8s + 12 = 0

doing middle term factorisation

s²-(6+2)+12=0

s²-6s-2s+12=0

s(s-6)-2(s-6)=0

(s-6)(s-2)=0

either

s=6

or

s=2

5) x ²+ 2x - 35 = 0

doing middle term factorisation

x²+(7-5)x-35=0

x²+7x-5x-35=0

x(x+7)-5(x+7)=0

(x+7)(x-5)=0

either

x=-7

or

x=5

6) r(r + 2) = 99

opening bracket

r²+2r=99

keeping all terms in one side

r²+2r-99=0

r²+(11-9)r-99=0

r²+11r-9r-99=0

r(r+11)-9(r+11)=0

(r+11)(r-9)=0

either

r=-11

or

r=9

7)k(k-4)=-3

opening bracket

k²-4k=-3

keeping all terms in one side

k²-4k+3=0

k²-(3+1)k+3=0

k²-3k-k+3=0

k(k-3)-1(k-3)=0

(k-3)(k-1)=0

either

k=3

or

k=1

8)t²+ 3t + 2 = 0

doing middle term factorisation

t²+(2+1)t+2=0

t²+2t+t+2=0

t(t+2)+1(t+2)=0

(t+2)(t+1)=0

either

t=-2

or

t=-1

9)m ^ 2 - 81 = 0

m²=81

doing square root in both side

$\sqrt{m²}=\sqrt{9²}$

m=±9

either

m=9

or

m=-9

10) h²- 17h + 70 = 0

doing middle term factorisation

h²-(10+7)h+70=0

h²-10h-7h+70=0

h(h-10)-7(h-10)=0

(h-10)(h-7)=0

either

h=10

or

h=7

❀ $\huge\underline{ \underline{Solution :-}}$

$( {y}^{2} + \frac{5}{7} )( {y}^{2} - \frac{14}{5} )$

To solve, use the algebraic identity ➺

(x + a)( x + b) = x² + (a + b)x + ab

$( {y}^{2} + \frac{5}{7} )( {y}^{2} - \frac{14}{5} ) \\ = ({y}^{2}) ^{2} + ( \frac{5}{7} + - \frac{14}{5} ) {y}^{2} + \frac{5}{7} \times - \frac{14}{5} \\ = {y}^{4} - \frac{73}{35} {y}^{2} - 2$

A tap can fill a bucket in 6 hours. After half the bucket is filled, three more similar taps are opened. What is the total time

Masja [62]

The total time taken to fill the bucket completely is 3 hours and 45 minutes.

<h3>What is Division?</h3>

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Let the volume of the bucket be represented by x. Then the rate at which the complete bucket can be filled is,

Rate = Total volume/ Time taken to fill the bucket

Rate = x / 6

Now, the time it will take for the half bucket, therefore, x/2 bucket to fill,

Rate = Volume / Time

x/6 = (x/2) / Time

Time = (x/2) / (x/6)

Time = 3 hours

Now, since three more such taps are opened, therefore, the rate of filling the bucket will be,

Rate = 4 × Rate of a single tap

= 4 × (x/6)

= 4x / 6

= 2x / 3

Further, the time it will take for the four taps to fill the half bucket is,

Rate = Volume / Time

2x/3 = (x/2) / Time

Time = (x/2) / (2x/3)

Time = 3/4 hours

Furthermore, the total time taken to fill the bucket completely is,

Total time = 3 hours + 3/4 hours

= 3 3/4 hours

= 3.75 hours

= 3 hours and 45 minutes

Hence, the total time taken to fill the bucket completely is 3 hours and 45 minutes.
