Answer:

x=6

Step-by-step explanation

2x-2.12=9.88

   +2.12  +2.12

    2x  =   12

12 divided by 2 is 6

x=6

To check you can do 12-2.12=9.88

Answer:

86% of 950 is 817

Step-by-step explanation:

You convert the fraction into a decimal by moving the point two spaces to the left. You then multiply .87 by 950 to get 817

Step-by-step explanation:

5√2/2 is the value of x in the triangle.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The hypotanenuse is 5 cm

The angle opposite to right angle is 45 degrees.

As it is a right angle one angle is 90 degrees.

This is a right angled isosceles triangle whose sides are in the ratio 1:1:√2.

In an isosceles right triangle, the equal sides make the right angle. They have the ratio of equality, 1 : 1.

So 5/√2.

Multiply numerator and denominator by √2

We get 5√2/2

Hence, 5√2/2 is the value of x in the triangle.

Answer:

The ratios in the simplest form is 5:3

Step-by-step explanation:

Given that:

2.5m to 150cm

We have to express these ratios in simplest form but we will convert the quantities into same unit first.

Therefore,

Converting meters into centimeters

1 meter = 100 cm

2.5 m = 100*2.5 = 250 cm

Ratio form;

250 cm : 150 cm

As both the number are multiples of 50,

[tex]\frac{250}{50}:\frac{150}{50}\\5:3[/tex]

Hence,

The ratios in the simplest form is 5:3

Answer:

8 bulbs

Step-by-step explanation:

In the model, each + represents a dollar

4 +s for the shipping cost, 20 +s for the total cost.

Therefore we have 2x (since each bulb is $2) + 4 = 20

2x = 16

x = 8

Step-by-step explanation:

x is the number of bulbs.

We have $2x + $4 = $20.

=> $2x = $16, x = 8.

Hence Sheila can order 8 flower bulbs.

Answer:

haircut =9 and hair color= 3

Step-by-step explanation:

Step one:

GIven data

let the haircut be x

and hair color be y in numbers.

so

18x+42y=288------------1

x+y=12---------------------2

from 1

x=12-y, put this in 2, we have

18(12-y)+42y=288

216-18y+42y=288

collect like terms

24y=288-216

24y=72

divide both sides by 24

y=72/24

y=3

put y= 3 in 2

x+3= 12

x= 12-3

x=9

Answer:

3.33 meters per second

Step-by-step explanation:

1 1/2 laps = 200+100 = 300

use formula: distance = rate x time

t = time (in meter per second)

300 = 90t

t = 300/90 which reduces to 3.33/1

Answer:

22.7604763 degrees

Step-by-step explanation:

Note that the answer is NOT 20 degrees.

She adjusted the ramp to half the original incline

Therefore we have tan 40 = x = 0.839099631.

We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815

Taking the arctan of both sides, we get

y = arctan(0.419549815) = 22.7604763 degrees

Answer:

x = 16, y = 140

Step-by-step explanation:

(8x + 12)° and (3x - 8) are adjacent angles and are supplementary, sum to 180°

8x + 12 + 3x - 8 = 180

11x + 4 = 180 ( subtract 4 from both sides )

11x = 176 ( divide both sides by 11 )

x = 16

Then

8x + 12 = 8(16) + 12 = 128 + 12 = 140

(8x + 12) and y are alternate angles and are congruent , so

y = 140

Hope that helps.

Step-by-step explanation:

Nø of sample space, n(s) = 40

nø of unripe oranges, n (u) = 12

no of ripe oranges, n (r) = 40 - 12 = 28

Now

The probability that it is ripe is, P(E)

= n(r) / n(s)

= 28 / 40

= 7 / 10

Also the probability that it is unripe is, P(E)

= n(u) / n(s)

= 12 / 40

= 3 / 10

Answer:

Assuming you mean width not breadth (What is that)

The width would be: 35m

Step-by-step explanation:

Now its pretty staight forward

We know that the length is 42m

And the permineter is 154m

We know that the perimeter is the 2 widths and 2 lengths all added up to each other (basically very side added up)

An eaution could be used like, 2w+2l=154

We know length is 42 so

2w+2*42=154

Now just solve for W

2*42=84

2w+84=154

154-84= 70

70=2w

70/2=35

w=35
