what is the square root of 1225,1764,11025 ​

Answer:

System of Equations is given as:

c = 2h - 1...... Equation 1

1.8c + 3h = 288.60....Equation 2

Step-by-step explanation:

Let us represent

The number of Cold lunch = c

The number of Hot lunch = h

The number of cold lunches the teacher bought was 1 fewer than twice the number of hot lunches the teacher bought.

Hence:

c = 2h - 1

At a school cafeteria a cold lunch costs $1.80, and a hot lunch costs $3.00. During one school year a school year a teacher spent a total of $288.60 on cold lunches and hot lunches.

Hence:

$1.80 × c + $3.00 × h = $288.60

1.8c + 3h = 288.60....Equation 2

The system of equations can be used to find c, the number of cold lunches, and h, the number of hot lunches, the teacher taught during the school year is given as:

c = 2h - 1...... Equation 1

1.8c + 3h = 288.60....Equation 2

The system of equations that can be used to calculate the number of hot and cold lunches is [tex]\mathbf{1.80c +3.00h = 288.60}[/tex] and [tex]\mathbf{c = 2h - 1}[/tex]

Let h represents hot lunch, and c represents cold lunch.

So, we have:

[tex]\mathbf{1.80c +3.00h = 288.60}[/tex]

[tex]\mathbf{c = 2h - 1}[/tex]

Substitute [tex]\mathbf{c = 2h - 1}[/tex] in [tex]\mathbf{1.80c +3.00h = 288.60}[/tex]

[tex]\mathbf{1.80(2h -1) +3.00h = 288.60}[/tex]

Expand

[tex]\mathbf{3.60h -1.80 +3.00h = 288.60}[/tex]

Collect like terms

[tex]\mathbf{3.60h +3.00h = 288.60 + 1.80}[/tex]

[tex]\mathbf{6.60h = 290.4}[/tex]

Divide both sides by 6.60

[tex]\mathbf{h = 44}[/tex]

Substitute 44 for h in [tex]\mathbf{c = 2h - 1}[/tex]

[tex]\mathbf{c = 2(44) - 1}[/tex]

[tex]\mathbf{c = 83}[/tex]

Hence, the system of equations that can be used to calculate the number of hot and cold lunches is [tex]\mathbf{1.80c +3.00h = 288.60}[/tex] and [tex]\mathbf{c = 2h - 1}[/tex]

Answer:

the radius is 2.66ft

Step-by-step explanation:

my process of elimination:

first one: ❌ the radius is half of the length across (the dot) so 5.32ft divided by 2 it would be 2.66ft

sec. one: ❌ unlike the radius (which is half of the length across) the diameter is the full length across so the diameter would be 5.32ft

third one: ❌ actually almost tricked me then I remembered the circumference is for all around. this measurement only accounts for the diameter (5.32ft) and the radius (2.66ft)

fourth one: ✅simply was the truth. the radius is half of the diameter so if the diameter is 5.32ft then the radius is 2.66ft

Answer:

A is the answer ..........

Step-by-step explanation:

Answer:

Here are a few ways that I do that:

18 * 5 is the same as (10 + 8) * 5, which equals 50 + 40, which is 90

It's also the same as (20 - 2) * 5, which equals 100 - 10, again, 90

It's also 9 * 2 * 5, which equals 9 * 10, or 90

It's also 3 * 6 * 5, or 3 * 30, which is 90.

Answer:

12 feet

Step-by-step explanation:

Given that,

The ramp connects to the truck 5 feet above the ground, and the length of the ramp from the truck to the ground is 13 feet long.

Now we need to find the distance along the ground from the truck to the end of the ramp.

Here,

5 feet will be perpendicular distance, 13 feet will be hypotenuse and we need to find the base.

Using Pythagoras therorem to find it :

[tex]b=\sqrt{13^2-5^2} \\\\=12\ \text{feet}[/tex]

So, the required distance is 12 feet.

Answer:

Her salary for the month = $7260

Step-by-step explanation:

Amount sold = $62,000

Percentage rate = 3%

Salary from commission rate = Amount sold × Percentage rate

                                                = $62,000 × (3 / 100) = $1860

Total salary = Base salary + Salary from commission rate

                   = $5,400 + $1860

                   = $7260

Therefore, her salary for the month = $7260

Step-by-s First of all, note that 15 is the same as 15/1 since 15 divided by 1 is 15. Therefore, start by setting up the problem like this

Step 2: Multiply

Multiply the numerators together (15 x 2 = 30) and multiply the denominators together (1 x 3 = 3) and make it into one fraction like so:

Step 3: Minimize

The greatest common factor of 30 and 3 is 3. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:

Step 4: Convert

Convert the improper fraction above to a whole number to get the answer:

That's it! Now you know how to calculate 15 times 2/3.

Step-by-step explanation:

Answer:

95°

Step-by-step explanation:

Well first draw a parallel to p, let's say r

so we have that

[tex]\angle 2+\angle3=\angle1[/tex]

and

[tex]\angle y=148\\\\\angle x +63=180\\\\\angle x=117[/tex]

so now by internal angles of parallels we know that

[tex]\angle x +\angle 2 = 180\\\\\angle y +\angle 3 = 180[/tex]

which is

[tex]117+\angle 2 = 180\\\\\longrightarrow \angle 2 = 63\\\\148+\angle 3 = 180\\\\\longrightarrow \angle3=32[/tex]

so

[tex]\angle 1 = 63+32\\\\\angle 1 = 95[/tex]

Complete question :

Carly purchased 9 1/2 pints of ice cream for a party. If each guest will be served exactly 3/5 pint of ice cream, what is the greatest number of gusts that Carly can serve

Answer:

15 guests

Step-by-step explanation:

Given that:

Total pints of icecream = 9 1/2

Fraction of ice cream pints per guest = 3/5 pints

Number of guest that can be served :

Total pints / fraction per guest

9 1/2 ÷ 3/5

19/2 * 5/3

95 / 6

= 15.8 guest

Hence, greatest Number of guest that can be served = 15

Step-by-step explanation: i believe these are correct.

Answer:

a = 6

b = 2

Step-by-step explanation:

Here, we want to take all values of p up and all values of q down

From the division, 9

goes up and the term above comes down

We have all the following indices rule to use;

(a^x)^y = a^xy

a^x * a^y = a^x + y

a^x / a^y = a^x-y

Let us evaluate all p terms;

p^12/p^4 = p^8

Let us evaluate all q terms

q^16/q^10 * 1/q^2

= q^6/q^2 = q^4

Let us evaluate all number terms

We have;

2^4/-3^2 * 9/4^2

= 16/9 * 9/16 = 1

All

number terms canceled out

Now, let us work with the exponents;

For the p terms;

p^8 = p^a+b

a + b = 8 •••••••••(i)

For the q terms;

q^4 = q^a-b

a-b = 4 ••••••••••(ii)

Add both equations

2a = 12

a = 12/2 = 6

For b;

a-b = 4

6-b = 4

b = 6-4

b = 2

Answer:

16

Step-by-step explanation:

each pound has 3.6 cups

1/4 of a pound can be multiplied

3.6 x 1/4 =  0.9

then we subtract 4 - 3.6 = 0.4 say if the question was for one pound

But we have to find  14.4 cups instead as;

3.6 x 4 = 14.4 = 4 pounds

We go back to 0.9 are first smaller serving = 1/4 cup

14.4/0.9 = 16
