Answer:

given us,

width= 10.0

length= 5.0

here,

w×d= 10.0× 5.0

= 50

now

cm/ m

=1.0/ 4.5

= 2.22

w×d x cm.m× 100

50/ 2.22× 100

2252.25

Step-by-step explanation:

we have to solve and multiply

See Explanation

Step-by-step explanation:

1. By interior angle sum Postulate of a triangle.

[tex] m\angle a+ m\angle y +m\angle z= 180\degree.... (1)\\\\

m\angle a+ m\angle w +m\angle x= 180\degree.... (2)\\\\[/tex]

From equations (1) & (2), we find:

[tex] m\angle a+ m\angle y +m\angle z= m\angle a+ m\angle w +m\angle x\\\\

m\angle y +m\angle z= m\angle w +m\angle x\\[/tex]

Hence proved

2. In [tex] \triangle PQS, \: \angle QSR [/tex] is exterior angle.

Therefore, by remote interior angle theorem, we have:

[tex] m\angle QPS + m\angle PQS= m\angle QSR\\\\

x + m\angle PQS= 2x\\\\

m\angle PQS= 2x-x\\\\

m\angle PQS = x.... (1)\\\\

m\angle QPS = x.... (given).... (2)\\[/tex]

From equations (1) & (2), we find:

[tex] m\angle PQS = m\angle QPS\\\\

\therefore \angle PQS \cong \angle QPS\\\\

\therefore PS \cong QS\\(sides\: opposite \: to\: congruent \:\angle s) \\\\[/tex]

[tex] \therefore \triangle PQS [/tex] is an isosceles triangle.

Thus proved.

Answer:

C.

Step-by-step explanation:

1.) switch x and y

x=(7y+18)/2

2.) multiply both sides by 2

2x=7y+18

3.) subtract 18 from both sides

2x-18=7y

4.) divide both sides by 7

(2x-18)/7=y

Answer:

m = -10

General Formulas and Concepts:

Order of Operations: BPEMDAS

Properties

Step-by-step explanation:

Step 1: Define equation

m + 6 = -4

Step 2: Solve for m

Step 3: Check

Plug in m to verify it's a solution.

A + B = 65...Equation 1

B + C = 140...Equation 2

Solve Equation B for C.

C = 140 - B

The sum of the angles in a triangle is 180 degrees.

We know that A + B = 65.

65 + C = 180

We know that C = 140 - B.

65 + 140 - B = 180

205 - B = 180

-B = 180 - 205

-B = -25

B = -25/-1

B = 25

Plug B = 25 into B + C = 140 to find angle C.

25 + C = 140

C = 140 - 25

C = 115

Angle B = 25°.

Angle C = 115°.

Answer:

substitution

Step-by-step explanation:

I would choose substitution because the first equation can easily be set in terms of y, then substituted into the second equation, while to eliminate you would have to multiply on of the equations by a number and make it negative in order to eliminate.

Answer:

An equation in standard form modeling this situation is:

75x + 50x = 425

Step-by-step explanation:

Let

x represent the number of pairs of socks you buy

y represent the number of pairs of gloves you buy

Each pair of Socks in store cost 75php, and each pair of gloves costs 50php. If you want to spend exactly 425php.

The equation is given as:

75php × x + 50php × y = 425php

= 75x + 50y = 425

Therefore,

the equation in standard form modeling this situation is:

75x + 50x = 425

Answer:

-10/7

Step-by-step explanation:

(-5/7)/(2/4) = (-5/7)/(1/2) = (-5/7)*(2/1) = -10/7

Answer:

{Height and radius not given}

Slope-Intercept Form - Y = Mx + b

Y = 1/4x + 1

Answer:

Step-by-step explanation:

5x - 4 > 12

5x > 12 + 4

5x > 16

x > 16/5

12x + 5 < -4

12x < - 4 - 5

12x < - 9

x < - 9/12

x < - 3/4

Option A is the correct answer

Answer:

0.30 per topping

Explanation:

3.35 - 2.75= 0.60

0.60 / 2 = 0.30

Answer:

The answer is (B. 18) and I believe this is correct because 2×18=36 & 3×18=54

Answer:

  B.  75.8 ft²

Step-by-step explanation:

The height of each triangle can be found using the Pythagorean theorem. The given edge length (7 ft) is the hypotenuse of the triangle, and the base edge length is twice one leg of the triangle.

The height of the triangle on the 2 ft faces is ...

  √(7² -1²) = √48 = 4√3

The height of the triangle on the 8 ft faces is ...

  √(7² -4²) = √33

The areas of the triangular faces are the product of the height and half the base length:

  A = 1/2bh

  2 ft edge triangle area = (1/2)(2 ft)(4√3 ft) = 4√3 ft²

  8 ft edge triangle area = (1/2)(8 ft)(√33 ft) = 4√33 ft²

__

The area of the rectangular base is ...

  A = LW

  A = (8 ft)(2 ft) = 16 ft²

__

The total surface area of the pyramid is the sum of the areas of the triangular faces and the area of the rectangular base.

  2(4√3 +4√33) +16 = 8(2+√3+√33) ≈ 75.813

The total surface area is about 75.8 ft².

Answer:

I think it is b

Step-by-step explanation:

Answer:

B

graph B represents 1/2#1/6

1/2#1/6=3

Answer:

[tex]y=\frac{5}{3}x+4\frac{2}{3}[/tex]

Step-by-step explanation:

slope-intercept form: y = mx + b

Given:

Slope(m) = [tex]\frac{5}{3}[/tex]

Point = (-1, 3)

To write the equation in slope-intercept form we need to know the slope(m) and the y-intercept(b). Since we already know the value of m, we can use it and the given point to find b:

[tex]3=\frac{5}{3}(-1)+b[/tex]

[tex]3=-\frac{5}{3}+b[/tex]

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

Now that we know the values of b and m, we can write the equation:

[tex]y = \frac{5}{3}x+4\frac{2}{3}[/tex]

Step-by-step explanation:

The more regular way of presenting such a graph is y = -2/3 x + 20

(Put the x on the right and made sure that the y has a coefficient of 1.)

Coefficient means the number in front of the letter (in this case).

x intercept = 30

(30,0)

y intercept = 20

(0,20)

The intercepts mean

The y intercept means the whole garden contains nothing but lettuce. (20)

The x intercept means the whole garden contains nothing but tomatoes.(30)

Answer:

g=12/7

Step-by-step explanation:

Answer:

21/10 mph

Step-by-step explanation:

When you divide a fraction with another fraction, the number after the division sign gets flipped (meaning that the numerator and denominator switch so 1/2 would be 2/1)

So using that we can solve this:

7/5 / 2/3

7/5 * 3/2

21/10 miles per hour

Step-by-step explanation:

Volume of a cylinder is:

V = πr²h

V = (3.14) (4 in)² (5 in)

V = 251.2 in³

Volume of a cone is:

V = ⅓ πr²h

V = ⅓ (3.14) (4 in)² (15 in)

V = 251.2 in³

The volumes are equal.

Answer:

12[tex]x^{4}[/tex]y[tex]z^{7}[/tex]√3x

Step-by-step explanation:

2√108[tex]x^{9}[/tex]y²[tex]z^{14}[/tex]

so you will need two of something to take one out from under the squareroot

we can rewrite [tex]z^{14} = z^{7} *z^{7}[/tex] so we can take a [tex]z^{7}[/tex] out

we can rewrite y² as y*y so we can take a y out

we can rewrite [tex]x^{9}[/tex] as [tex]x^{4} *x^{4} *x[/tex] so we can take a [tex]x^{4}[/tex]out

for 108 think what is the smallest prime number that divides 108 and is 2

108= 2*54

same algorithm, smallest prime number that divides 54 is 2 so

108=2*2*27

same algorithm, smallest prime number that divides 27 is 3 so

108=2*2*3*9

we know 9 is 3*3 so

108=2*2*3*3*3 we can take out one 2 and one 3

put them all toghether now

2*2*3*[tex]x^{4}[/tex]*y*[tex]z^{7}[/tex]√3x = 12[tex]x^{4}[/tex]y[tex]z^{7}[/tex]√3x
