19. Solve

Answer:

16

Step-by-step explanation:

The area of a parallelogram is b * h, where b and h are the base and height respectively. We know the base but not the height. However, we see a right triangle that has the height and 3 as legs and 5 as the hypotenuse. Pythagorean Triples tell us that the height is 4 and the area will be 4 * 4 = 16 sq. units. Hope this helps!

Answer:

3/20 or .15

Step-by-step explanation:

You need to find 3/5 of 1/4, so you need to multiply

3/5*1/4= 3/20

3/20 or .15

Answer:

x = 3, y = 6

Step-by-step explanation:

In the figure attached,

If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.

By this property,

[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]

[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]

[tex]\frac{AD+BD}{AD}=\frac{AE+EC}{AE}[/tex]

[tex]\frac{3}{2}=\frac{x+1.5}{x}[/tex]

3x = 2x + 3

3x - 2x = 3

x = 3

Similarly, [tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]

[tex]\frac{3}{2}=\frac{y}{4}[/tex]

y = [tex]\frac{3\times 4}{2}[/tex]

y = 6

Answer:

x= number of girls

y= total

Step-by-step explanation:

y= 1x

y= 1(5)

y= 5 marshmallows

Answer:

x=50

Step-by-step explanation:

Simplifying

x = 50

The conversion rate of millimetres to centimetres is 10 = 1 (Meaning 10 millimetres will equal one centimetre).

Knowing this, we can convert the centimetres to millimetres by multiplying by 10.

30 x 10 = 300

So a walking stick is 300 millimetres long.

To find the difference, we need to subtract the larger number from the smaller one.

300 - 10 = 290

Therefore the answer is 290mm.

Hope this helps! :)

Answer: (5, 12, 13).

Step-by-step explanation:

Pythagorean triples are any three side lengths of a right triangle that are all whole numbers.

The most common triples are (3, 4, 5), (5, 12, 13), and (9, 40, 41).

You can test the options given in the Pythagorean theorem to see if they make the theorem correct.

25 + 64 = 100 is not correct.

9 + 16 = 36 is not correct.

25 + 144 = 169 is correct.

1 + 1 = 4 is not correct.

The correct choice is (5, 12, 13).

Answer:

[tex](5 \:, \: \: 12 \: , \: \: \: 13)[/tex]

Third answer is correct

Step-by-step explanation:

PYTHAGORAS theorem

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

Let's take one by one.

1)(5,8,10)

[tex] {5}^{2} + {8}^{2} = {10}^{2} \\ 25 + 64 = 100 \\ 89 = 100[/tex]

No,it's not correct.

2)(3,4,6)

[tex] {3}^{2} + {4}^{2} = {6}^{2} \\ 9 + 16 = 36 \\ 25 = 36 [/tex]

No, it's not correct.

3)(5,12,13)

[tex] {5}^{2} + {12}^{2} = {13}^{2} \\ 25 + 144 = 169 \\ 169 = 169[/tex]

Yes,it's correct

4)(1,1,2)

[tex] {1}^{2} + {1}^{2} = {2}^{2} \\ 1 + 1 = 4 \\ 2 = 4 [/tex]

No, it's not correct

SO, IT'S CLEAR THAT THE CORRECT ANSWER IS THE THIRD ANSWER

Answer:

360 = x+123+ 90

x = 147

Step-by-step explanation:

The three angles form a circle which is 360 degrees

360 = x+123+ 90

Subtract 123 and 90 from each side

360 -123 - 90 = x

147 = x

Answer:

The expression is; x^2 – 4c + 4

Step-by-step explanation:

For the expression to be a perfect square, let us say the constant term should be assigned as ⇒ c;

This creates of following expression;

x^2 - 4x + c

In order to be a perfect square, the discriminant needs to be zero ;

( - 4 )^2 - 4 * ( 1 )c = 0 ,

16 – 4c = 0 ,

4c = 16 ,

c = 4 ,

Solution; The expression is, therefore; x^2 – 4c + 4

Answer:

B, C and E

Step-by-step explanation:

To get the expressions that have the same solution as the given expression;

first, we need to get the result of the given expression.

-4(6) = -4 * 6

-4(6) = -24

the next step is to test each of the given options.

A.

-4(-6) = -4 * -6

-4(-6) = 24

B.

4(-6) = 4 * -6

4(-6) = -24

C.

6(-4) = 6 * -4

6(-4) = -24

D.

-8(2) = -8 * 2

-8(2) = -16

E.

12(-2) = 12 * -2

12(-2) = -24

From options A through E,

option B,C and E have the same result as the expression in the question

Answer:

$7.20

Step-by-step explanation:

The first step is to convert 1 1/4 to decimal form. 1/4=0.25, which when added to the 1 gives a total weight of 1.25 pounds. Dividing this by the price to find the unit price, you get 9/1.25=$7.20 per pound of turkey. Hope this helps!

Unit price is the price when something is $1, so what you need to do is 9/1.25. The answer is $7.20, so that is the unit rate. I hope this helps.

Answer:

No triangle

Step-by-step explanation:

All triangles must have angles that measure up to 180 degrees. When you add 32, 32, and 126 you get 190. That means that no triangle can be formed.

Answer:

It’s 157.5

Step-by-step explanation:

Answer:

4.5

Step-by-step explanation:

you do PEMDAS

you divide 1 by 4

then multiply it by 6

then 6 minus 1.5 is 4.5

i may be wrong

Answer:

Each given point will lie within the viewing window, [tex]Xmin=-12[/tex], [tex]Xmax=1[/tex], [tex]Xscl=1[/tex], [tex]Ymin=-8[/tex], [tex]Ymax=6[/tex], [tex]Yscl=1[/tex].

Step-by-step explanation:

The given points are (-11,5),(0,-4),(0,-7).

Here, the minimum values of x is -11 and maximum value of x is 0.

It means [tex]Xmin[/tex] must be less than -11 and [tex]Xmax[/tex] must be greater than 0.  

The minimum values of y is -7 and maximum value of y is 5.

It means [tex]Ymin[/tex] must be less than -7 and [tex]Ymax[/tex] must be greater than 5.  

Therefore, each given point will lie within the viewing window

[tex]Xmin=-12[/tex]

[tex]Xmax=1[/tex]

[tex]Xscl=1[/tex]

[tex]Ymin=-8[/tex]

[tex]Ymax=6[/tex]

[tex]Yscl=1[/tex]

Note: For this question many answers are possible.

Answer:

The zeros are {2, 3}

Step-by-step explanation:

Please use " ^ " to indicate exponentiation:  

F(x) = x^3 - 5x^2 - 6x

Factoring out x, we get:

F(x) = x(x^2 - 5x - 6)

Factoing the quadratic, we get:

F(x) = x(x - 3)(x - 2) = 0

The zeros are {2, 3}

Answer:

Base: 16 cm

Height: 48 cm

Step-by-step explanation:

Let's call the length of the base b, and the length of the height h. Since the formula for the area of a triangle is bh/2, you can set up the following equations:

[tex]h=3b\\\dfrac{bh}{2}=384\\ \dfrac{b(3b)}{2}=384\\\dfrac{3b^2}{2}=384\\3b^2=768\\b^2=256\\b=16\\h=16\cdot 3=48[/tex]
