-9.1-3.7x=9x+9.2 rounded to the nearest tenth

Answer: First Solution

Step-by-step explanation:

We can solve this by using the Quadratic Formula, which is

(-b±√b²-4ac)/2a

First off we can find the discriminant. Replacing b with 7, a with 2, and c with -5 gives us a discriminant of 89. But there are two solutions with the discriminant 89.

The second deciding factor would be finding the denominator, which is 2a. Replacing a with 2 gives us 4.

We already know the solution is the first one, but it's important to find the value of the first part of the numerator, -b. Using that we can tell that it's -7, and not 7.

Answer:

x = 30

Step-by-step explanation:

Put in proportions [tex]\frac{x}{45}[/tex] = [tex]\frac{18}{27}[/tex]

Cross multiply and get 27x = 45 x 18

OR...

27x = 810.

THEN...

divide by 27 on both sides to get 30

x = 30

The first step is to find the area of the figure amd then multiply it by the weight of per metre...

[tex] \sf \: area = length \times width[/tex]

[tex] \bf \: area = 0.6 \times 2[/tex]

[tex] \bf \: area = 1.2 \: {m}^{2} [/tex]

[tex] \tt \: 1.2 \:{m}^{2} = 1.2 \: kg[/tex]

The framework is made up of 5 rods, So the weight will be

➪ Thus, The weight of theframework is 6 kilograms...~

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Probability is calculated as

P = [tex]\frac{favourable outcome}{number of outcomes}[/tex]

A favourable outcome is an even number , that is 2, 4, 6 , a total of 3

number of outcomes = 6 , that is 1, 2, 3, 4, 5, 6

Then

P( even number) = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

Step-by-step explanation: The area of a circle can be found with the equation A=(pi)*r^2. Use the equation to find the answer:

A=(pi)*5.5^2 (or A=3.14*5.5^2)

A=94.99 or 95.03 in exact pi

Answer:58.272

Step-by-step explanation: This is the answer for maths watch

The perimeter of the shaded shape is 58.29  cm.

                             [tex]P = \pi r_1 + \pi r_2 + (d_1 - d_2)\\P = (\pi \ \frac{20}{2} ) + (\pi \ \frac{12}{2} ) +(20 -12)\\P = \pi ( 10 + 6) +8\\P = 16\pi +8\\P = 58.29 \ cm[/tex]

Answer:

Step-by-step explanation:

Answer:

x = 15√2

Step-by-step explanation:

Since the two angles on the triangle are the same, we can conclude that x is equal to the side that is adjacent to it too ( not the hypotenuse).

We will have x = a to use this pythagorean theorem as follows.

We will get the equation,

a = b

where

a^2 + b^2 = c^2

so,

a^2 + a^2 = c^2

2a^2 = 30^2

2a^2 / 2 = 900 / 2

√a^2 = √450

a = √450

a = 15√2

Answer:

Let

Point 1 ----------> (5, 2)

Point 2 ----------> (–6, 2)

we know that

the distance between two points it is calculated with the formula

d=√[(y2-y1)²+(x2-x1)²]

then

d=√[(2-2)²+(-6-5)²]

d=√[(0)²+(-11)²]

d=√[121]

d=√121-----------> d=11 units

the answer is 11 units,

Also, The segment is horizontal because the y-coordinates are the same. To find the distance, you can count the spaces between the points. The segment is 11 units long.

Step-by-step explanation:

let Rehman invests in 8%=$x

simple interest=x*0.08*1=0.08 x

investment in 7.5%=$(3050-x)

simple interest=(3050-x)*0.075*1=228.75-0.075x

total interest=0.080 x+228.75-0.075 x=0.005x+228,75

0.005x+228.75=242

0.005 x=242-228.75

Milk, tea and pearls in the ratio of 4:3:1 -> The milk = 4x, tea = 3x and pearls = x

So, 1560g is equal to 4x + 3x + x = 8x

x = 1560 / 8 = 195
3x = 195 x 3 = 585
4x = 195 x 4 = 780

So, she used 780g of milk, 585g of tea and 195g of pearls.

Answer:

Milk= 780g

Tea= 585g

Pearls= 195g

Step-by-step explanation:

So we know that all together there is 1560g. So what we do is add the ratio numbers together which is 4+3+1. This gives us 8. Next, what we can do is how much is 1 (ratio). So we do 1560g/8. This gives us 195g. Now the last step is to multiply 195g with each ratio number given. So milk is represented as 4. So therefore milk would be 4 multiplied by 195g. This means milk= 780g. Tea = 3 multiplied by 195g. Thus, this gives us 585g. The last one which is pearls is 195g as it is multiplied by 1. To check the answer, you can add the three numbers which are 780g+ 585g+195g= 1560g.
