Answer:

Hello! answer: 29

Step-by-step explanation:

10/\2 is just 10 × 10 and 10 × 10 = 100 3/5/\2 is just 3/5 × 3/5 and 3/5 × 3/5 = 9/25 now we can do the math! 100 × 9/25 = 36 and 36 - 7 = 29 So 29 is the answer hope that helps!

Answer:

Original price of bicycle = $864

Step-by-step explanation:

Given:

Rate of tax = 20%

Price pay by Mathew = $1,080

Find:

Original price of bicycle

Computation:

Original price of bicycle = Price pay by Mathew[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-0.2)]

Original price of bicycle = 1,080[1 / (0.8)]

Original price of bicycle = 1,080[1.25]

Original price of bicycle = 1,080[1.25]

Original price of bicycle = $864

Answer: -2.10

Step-by-step explanation:

just took the test

Answer:

-2.1

Step-by-step explanation:

x= 4/5

you put in 4/5 where x is supposed to be so you get: -2/5 - 4/5 + (-9/10)

-2/5 - 4-5 = -6/5

-6/5= -12/10

-12/10 + -9/10= -21/10 = -2.1

Answer: [tex]\$10.7[/tex]

Step-by-step explanation:

Given

Nina bought a computer mouse for $9.30

She paid a $20 dollar bill

The money she received is the difference between what is paid and the cost of the mouse i.e.

[tex]\Rightarrow 20-9.3\\\Rightarrow \$10.7[/tex]

Therefore, she gets [tex]\$10.7[/tex] after deductions.

HOPE THAT HELPS a bit when trying to solve the whole thing

Answer:

80 meters

Step-by-step explanation:

Length of rectangular field = x

Width of rectangular field = 50

Meters of Fencing required = perimeter of rectangle = 260 m

Perimeter of a rectangle = 2(length + width)

260 = 2(x + 50)

260 = 2x + 100

260 - 100 = 2x

160 = 2x

x = 160 / 2

x = 80 meters

Answer:

hi

Step-by-step explanation:

Step-by-step explanation:

Use the formula for compound interest

f/p: f =p(1+i)^n

p = 3300

i =8% = 0.08

n = 9 years

A = p(1+r)^t

A = 3300(1+0.08)⁹

A = 3300× 1.99

A= 6596.71 dollar ~ 6597 dollar.

Answer:

12

Step-by-step explanation:

18*2=36, 60-36=24, 24/2=12

The width of the room if the length is 18m is 1.66m.

We have given that,

Perimeter=60 and length=18m

P=2(l+w)

Where the l is the length and

W is the width

Perimeter=60 and length=18m.

Use this value in the formula of perimeter

60=2(18×W)

Divide both sides by 2

30=18w

isolate the w

Therefore, divide both sides by 18.

30/18=w

W=1.66m

Therefore the width of the room if the length is 18m is 1.66m.

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the map or the scale length of the plants are not given.

To solve this, I will assume that:

[tex]Scale\ Distance = x[/tex]

[tex]Scale\ Ratio = 1\ unit : 1\ km[/tex]

Required

The total length

To get the total length (actual length), multiply the scale ratio by the scale distance;

[tex]Actual = Scale\ Distance * Scale\ Ratio[/tex]

So, we have:

[tex]Actual = x * 1km[/tex]

[tex]Actual = x\ km[/tex]

Assume that:

[tex]x = 5[/tex]

The total length will be:

[tex]Actual = 5km[/tex]

Answer:

third side is 2√33

Step-by-step explanation:

Hi there!

We need to find the third side (hypotenuse, or the side opposite to the right angle) of the triangle, and we're given the measures of the 2 other sides (legs, or the sides make up the right angle)

To find the hypotenuse, we can use Pythagorean theorem, which is given as:

a²+b²=c², where a and b are the legs, and c is the hypotenuse

as stated above, we know that the legs are 7 and √83

substitute them as a and b into the theorem

remember that (√x)²=(√x)(√x)=x

7²+(√83)²=c²

raise all numbers (multiply 7 by itself and multiply √83 by itself)

49+83=c²

add 49 and 83 together

132=c²

take the square root of both sides

√132=c

the question asks for simplest radical form, written as x√y, where x is the square root of a perfect square, and y is what's left after the prefect square is pulled out. For example, 2√3 is √12 (12 is 4*3, and 4 is a perfect square. Recall that √xy is equal to √x*√y. Taking the square root of 4 gives us 2, while taking the square root 3 gives us √3. Multiplying them together makes the number 2√3)

132 is divisible by 4 (the last two digits makes 32, which is divisible by 4). 132/4=33

so 132 is 4*33

pull out 4 from under the radical, take the square root of it, and leave √33 as is

the simplified radical form is 2√33

So the third side is 2√33
