Answers

Answer:

850 grams of rice

Step-by-step explanation:

340 g / 4 people

10/4 = 2.5

340 * 2.5

850

The quantity of rice needed for 10 people if, A recipe uses 350 grams of rice, The recipe serves 4 people, is 875 grams.

What is division?

The division is the basic arithmetic operation, in which you are separating the number into some parts.

Given:

A recipe uses 350 grams of rice, The recipe serves 4 people,

Calculate the quantity of rice for serving one person as shown below,

The quantity of rice for one people = Total quantity of rice / total number of people

The quantity of rice for one people = 350 / 4

Calculate the quantity of rice for 10 people as shown below,

The quantity of rice for 10 people = 350 / 4 × 10

The quantity of rice for 10 people = 3500 / 4

The quantity of rice for 10 people = 875

Thus, the quantity of rice needed for 10 people is 875 grams.

Mrs. Johnson measured 3 rectangular rooms that she wants to tile. What is the total area of the​ rooms?

Answers

Answer:

Find the area of each room and add the areas

Step-by-step explanation:

Please find the full question in the attached image

the area of rectangle is length x breadth. The area of each room would be found and the three areas would be added together

for example ,

dimension of room 1 = 5 x 3

dimension of room 2 = 2 x 3

dimension of room 3 = 4 x 5

area of room 1 = 15

area of room 2 = 6

area of room 3 = 20

total area = 15 + 6 + 20 = 41

Kenny buys a new drill for $129.90 plus 9.5% sales tax. How much does Kenny pay in total?Round the answer to the nearest cent.

Answers

Answer:

Kenny pays $142.24 in total.

Step-by-step explanation:

In order to find the total amount that Kenny pays, you have to calculate the 9.5% of the price of the drill as this is the sales tax and then, you have to add that amount to the price:

$129.90*9.5%=$12.34

$129.90+$12.34=$142.24

According to this, the answer is that Kenny pays $142.24 in total.

At a local coffee shop, three coffees and two muffins cost a total of $7.00. Two coffees and four
muffins cost a total of $8.00. How much would six cups of coffee and 1 muffin cost?

Answers

Answer:

$10.25

Step-by-step explanation:

Set up a system of equations, so 3c + 2m = 7 and 2c + 4m = 8, where c = the cost of coffees, and m = cost of muffins

To solve multiply the first equation by -2(3c + 2m=7) so you get -6c -4m = -14 now add the two equations

-6c - 4m = -14

2c + 4m = 8   notice that -6c + 2c = -4c and -4m + 4m cancels, then -14+8=-6

so we have -4c = -6 so c = $1.50

To solve for m, substitute c = 1.50 so 3(1.50) + 2m = 7, so solve for m so

4.5 + 2m = 7, 2m = 2.5, so m = $1.25

So now solve the final problem 6(1.50) + 1(1.25) = $10.25

Which property is shown In the matrix addition above?

A. Inverse Property
B. Identity Property
C. Commutative Property
D. Associative Property

Answers

Answer :

Identity Property.

Step-by-step explanation:

Two matices are given to us , which are ,

Let A = [tex]\left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] [/tex] .

Let B = [tex]\left[\begin{array}{ccc} 0 & 0& 0 \\ 0 & 0 & 0 \end{array} \right] [/tex] .

Here since all the elements of Matrix B are 0 , its a null matrix . Hence adding any matrix to it will give the same matrix which is added . This property is called as Identity Property .

Adding both A and B ,

[tex]\implies A + B = \left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] + \left[\begin{array}{ccc} 0 & 0& 0 \\ 0 & 0 & 0 \end{array} \right] [/tex]

[tex]\implies A + B = \left[ \begin{array}{ccc} ( 6+0) & (-8+0) & (1+0) \\ (0+0) & (-2+0) & (-19 + 0 ) \end{array}\right] [/tex]

[tex]\red{\implies A + B = \left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] }[/tex]

Step-by-step explanation:

It looks like your proportion is ...

  y = k√x

Then k can be found as ...

  k = y/√x = 25/√3

__

For y = 100, the value of x can be found from ...

  100 = (25/√3)√x

A motorist drives 146km at a certain speed. She then increase this speed of by 19km/hr and take the same time to travel the next 16km. Find her speed for both part of the journey.​ Pleaseeeeeeeeeeee helpppppppppppp

Answers

Step-by-step explanation:

A motorist drives 146km at a certain average speed she then increases the speed by 9km/h and takes the same time to travel the next 164km.

find her speeds for both parts of the journey.

:

let s = his original speed

then

(s+9) = the increased speed

:

Write a time equation; time = dist/speed

 

146%2Fs = 164%2F%28%28s%2B9%29%29

cross multiply

164s = 146(s+9)

164s = 146s + 1314

164s - 146s = 1314

18s = 1314

s = 1314/18

s = 73 km/h is his original speed

Answers

Answer:

xy-3x=40, x=5

x(y-3)=40

y-3=(40/x)

y=(40/x)+3

y=(40/5)+3

y=8+3

y=11

If the variables x and y vary inversely then when x=-3 and y =-8

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Since x and y vary inversely, we can write the equation:

x y = k, where k is a constant of variation.

Using the given values, we can find k:

(-4)(-6) = k

k = 24

So the equation relating x and y is:

x y = 24

To find y when x = -3, we substitute x = -3 into the equation and solve for y:

(-3) y = 24

y = -8

Therefore, when x = -3, y = -8.

Rex is six times older than its sibling Spike. Rex's mother dino is ten times older than Rex. Rex's father dino is twice as old as Rex's mother. The sum of all the ages of the members of dino's family adds up to granduncle dino's age. The granduncle dino had just turned thousand years old the day the meteors hit the planet. How old was Rex when it became a fossil into the nearest Whole number?​

Answers

Answer:

30 years

Step-by-step explanation:

Let :

Spike's age = x

Rex age = 6x

Rex mother = 10 * 6x = 60x

Rex father = 2 * 60x = 120x

x + 6x + 60x + 120x = 1000

187x = 1000

x = 1000/ 187

x = 5.34

Hence, Spike's age, x = 5 years

Rex age = 5 * 6 = 30 years

On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2

a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).

You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.

To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10

Now that you know the length of the dotted line is 10 units, you can now solve for x

(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361
