Answer:

a triangle with a right angle

Step-by-step explanation:

Answer: A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

Step-by-step explanation:

[tex]\left[\begin{array}{ccc}7&31\\142&19\end{array}\right][/tex] = 7(19) - 142(31) = - 4269

[tex]\left[\begin{array}{ccc}7&11&21\\55&-8&2\\-16&-1&-9\end{array}\right][/tex] = 7(- 8)(- 9) + 11(2)(- 16) + 21(55)(- 1) - 21(- 8)(- 16) - 7(2)(- 1) - 11(55)(- 9) = 1768

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.

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.

Answer:

NO

Step-by-step explanation:

Either 3, 5 and 6 satisfy the Pythagorean Theorem or they do not.  Here we start with a^2 + b^2 = c^2 and substitute 6 for c (because 6 is the largest of the set):  Is 3^2 + 5^2 = 6^2?  9 + 25 = 36?  NO

Answer:

34.41º

Step-by-step explanation:

0.93 times 9=8.37 degrees per minute

7 times 8.37=58.59

93-58.59=34.41

Answer:

a; 3.45 * 10^3

b) 2.34 * 10^18

c) 80%

Step-by-step explanation:

a) 3450 in standard form

To write in standard form, we have to place a decimal at the back of the first non-zero number

we have this as ;

3.450

The count of numbers after the decimal point is 3

This will be the power to which 10 will be raised

We have this as;

3.45 * 10^3

b) 234 * 10^16

Let us write 234 in standard form

That will be;

234 = 2.34 * 10^2

So we have ;

2.34 * 10^2 * 10^16

Using the law of indices, we have;

2.34 * 10^(2 + 16) = 2.34 * 10^18

c) From the question, Kuwait is 4/5 of Hong kong’s population

Let Honk Kong’s population be x

4/5 * x = 2.4 million

4x = 5 * 2.4 million

x = 5 * 2.4/4

x = 5 * 0.6

x = 3 million

so writing the population of Kuwait as a percentage of that of Hong kong, we have

2.4/3 * 100%

= 0.8 * 100% = 80%

Step-by-step explanation:

Given [Missing Information]

[tex]Red = 12[/tex]

[tex]Blue = 10[/tex]

[tex]Green = 15[/tex]

[tex]Yellow = 13[/tex]

Way 1:

Add up the total marbles that are not red.

[tex]Not\ Red = Blue + Green + Yellow[/tex]

[tex]Not\ Red = 10 + 15 + 13[/tex]

[tex]Not\ Red = 38[/tex]

Divide by total marbles to get the probability;

[tex]Probability = \frac{Npt\ Red}{Total}[/tex]

[tex]Probability = \frac{38}{38 + 12}[/tex]

[tex]Probability = \frac{38}{50}[/tex]

[tex]Probability = 0.76[/tex]

Way 2:

Calculate the probability of choosing red

[tex]P(Red) = \frac{Red}{Total}[/tex]

[tex]P(Red) = \frac{12}{50}[/tex]

[tex]P(Red) = 0.24[/tex]

Apply complement rule (i.e. subtract it from 1)

[tex]P(Not\ Red) = 1 - P(Red)[/tex]

[tex]P(Not\ Red) = 1 - 0.24[/tex]

[tex]P(Not\ Red) = 0.76[/tex]

Answer: D. y = 3x + 2

Step-by-step explanation: because that's what it shows in the graph

Answer:

D. y = 3x + 2

Step-by-step explanation:

y = mx + b,

where m = slope = rise/run,

and b = y-intercept

From the graph we see that b = 2, s we have

y = mx + 2

Now we look for the slope. Start at (0, 2), the y-intercept, go up 3, a rise of 3, and right 1, a run of 1 to the next point on a grid line intersection.

m = slope = rise/run = 3/1 = 3

Now we have

y = 3x + 2

I hope this helps!

The value of x is 17

An equation between two variables that gives a straight line when plotted on a graph.

Given,

x represents a certain number

Number is multiplied by 3 = 3x

Adding 34 to the number = x+34

Given,

The number x is multiplied by 3 the result is the same as adding 34 to the number x​

Therefore

3x = x+34

3x-x =34

2x =34

x = 17

Hence, the value of x is 17

Answer:

Step-by-step explanation:

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

Answer:

x = 17

Step-by-step explanation:

corresponding interior angles are supplementary, meaning they have to add up to 180 degrees so

6x + 8 + 4x + 2 = 180°     then combine like terms ( 6x and 4x, 8 and 2 )

10x + 10 = 180         subtract 10 from both sides

        -10     -10

10x = 170            divide each side by 10

/10     /10

x = 17

Answer:

37 inches.

Step-by-step explanation:

Well, we know the formula is a²+b²=c²

So, first plug in leg one and leg two:

12²+35²=c²

Now, solve.

144+1225=c²

1369=c²

Okay, so we have to square root 1369 to find c.

The square root of 1369 is 37.

Therefore, the answer is 37 inches.

87.5

Step-by-step explanation:

The area of the deck is 87.5 square feet.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

The given figure, can be divided into two triangles and 1 rectangle.

Here, area of a triangle = 1/2 ×Base×Height

= 0.5×5×3

= 7.5 square feet

Area of right triangle = 1/2 ×5×10

= 25 square feet

Area of a rectangle = Length×Breadth

= 11×5

= 55 square feet

Total area = 55+25+7.5

= 87.5 square feet

Therefore, the area of the deck is 87.5 square feet.

Answer:

100 miles

Step-by-step explanation:

Given data

let the number of miles driven be x

and the total charge for x miles be y

Hence the expression for the total charge is

Rapid Rental Car

charges a $55.00 rental fee plus $0.25 per mile driven.

y= 55+0.25x--------------1

Capital Cars charges a $45.00 rental fee and $0.35 per mile driven.

y= 45+0.35x--------------2

Equate 1 and 2

55+0.25x= 45+0.35x

collect like terms

55-45=0.35x-0.25x

10=0.1x

x= 10/0.1

x= 100 miles

Hence the mile is 100 miles
