Step-by-step explanation:

16)

 [tex]\frac{4}{10} , \frac{32}{72}\\\\\frac{4}{10} = \frac{32}{72}[/tex]

Cross multiply,

4 * 72   = 32 * 10

  288   ≠   320

So, these are not in proportion.

17)

[tex]\frac{40}{25} = \frac{32}{20}[/tex]

Cross multiply,

40 * 20 = 32 * 25

800  = 800

So, these are in proportion.

18)

[tex]\frac{15}{45}=\frac{9}{c}[/tex]

Cross multiply,

15 * c = 9*45

      c = [tex]\frac{9*45}{15}[/tex]

      c = 9*3

     c = 27

19)

[tex]\frac{16}{120} = \frac{v}{15}[/tex]

Cross multiply

16 * 15 = v * 120

[tex]\frac{16*15}{120} =[/tex] v

v = 2

Answer:

I think answer is A

Step-by-step explanation:

Cause you notice time is the x and distance (meters) is the y. So 1 minute = 200 meters.

Answer:

D. 16 in.

Step-by-step explanation:

The radius of the circle is 8 in. The diameter of any circle is twice the radius.

2 x 8 = 16

The diameter is 16 in. long.

Algebra I

Step-by-step explanation:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Step 3: Solve for y

Answer:

x = -2

y = 20

Step-by-step explanation:

y = -7x + 6

y = -10x​

y = -10x

-7x + 6 = -10x

3x = -6

x = -2

y = -7x + 6

y = -7 ( -2 ) + 6

y = 14 + 6

y = 20

Answer:

2+2x(7/7)= 0 (you do what's in the parenthesis first)

2+ 2x (1) =0 (then you multiply, and anything times 1 is itself)

2 + 2x= 0 (subtract 2 from both sides to get the x-term alone)

2x= -2 (divide both sides by 2 to get x isolated)

x= -1 (is your answer)

Answer:

A. and C.

Answer:

All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power. So the length of the edge of a cube with a volume of 125 is 5.

Answer:

1.75 feet of wood

Step-by-step explanation:

350/200 = 1.75

x/1 = 1.75

Multiply both sides by 1 to isolate x.

x = 1.75

Answer:

[tex]Z=x+y[/tex]

[tex]x+y<20[/tex]

Step-by-step explanation:

Let the gallons of fuel used in the hybrid per week car be [tex]x[/tex] and [tex]y[/tex] be the number of gallons used in the pickup truck per week.

Number of miles driven using both vehicles is at least 500 per week. The inequality that represents the number of miles driven is.

[tex]40x+17y\geq 500[/tex]

The expression of total amount of fuel used would be [tex]Z=x+y[/tex].

Now the sum of the fuels used in both the cars is more than 20 gallons per week. The inequality that represents the total amount of gasoline used is

[tex]x+y<20[/tex]

Answer:

the answer is 18.1 1/10 is the same thing as .1

take the breadth as x and accordingly length as (x+18)

the formula for finding the perimeter of a rectangle is 2(l+b) now put the correct values as shown in the picture and form an equation this way you will be able to find x which is the breadth and length Is 18 morethan breadth ,now as u have found both length and breadth go ahead and find the area whose formula is length×breadth

Answer: d = 17

Step-by-step explanation:

d - 11 = 6

So, by adding 11 to each side you'd get rid of the -11 on the left and isolate the variable

d = 17

Answer:

yes

Step-by-step explanation:

u={1,2,3,4,5,6,7,8,9}

m={2,4,6,8}

N={1,2,4,8}

O={2,4,6,8}

Now

M intersection (N intersection O) = (M intersection N) intersection O

or , {2,4,6,8} intersection {2,4,8} ={2,4,8}

intersection {2,4,6,8 }

:. {2,4,8} ={2,4,8}

Answer:

50 hombres y 25 mujeres

Step-by-step explanation:

Sea m el número de hombres y w el número de mujeres.

El total es 75

Así; m + w = ​​75 •••••••• (i)

Además; 16% de m + 20% de w = 13

0,16 m + 0,2 w = 13

Multiplicar por 100

16m + 20w = 1300 ••••• (ii)

De i, m = 75-w 16 (75-w) + 20w = 1300

1200 - 16w + 20w = 1300

4w = 1300-1200

w = 100/4 w = 25

Recordar; w + m = 75

25 + m = 75

m = 75-25

m = 50

Answer:

Square root2 /3

Step-by-step explanation:

1. Multiply both numerator and denominator by square root of 2.

2. Square root 2 times itself is just 2 that so denominator is 5-2

3. 1 times Square root 2 is just Square root 2. So numerator is Square root 2

4. 5-2=3 so final answer is Square root 2 over 3

Answer:

-2.5 , -1 , 15.03 , 15.32

-10 , -6 1/2 , -1 , 0

0.02 , 0.2 , 2.02 , 2.2

Step-by-step explanation:

Answer:

-2.5 , -1 , 15.03 , 15.32

-10 , -6 1/2 , -1 , 0

0.02 , 0.2 , 2.02 , 2.2

Step-by-step explanation:

Given:

The two points are (-5,8) and (-3,1).

To find:

The distance between the given two points in simplest radical form.

Solution:

Distance formula: The distance between two points is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using distance formula, the distance between (-5,8) and (-3,1) is

[tex]d=\sqrt{(-3-(-5))^2+(1-8)^2}[/tex]

[tex]d=\sqrt{(-3+5)^2+(-7)^2}[/tex]

[tex]d=\sqrt{(2)^2+(-7)^2}[/tex]

[tex]d=\sqrt{4+49}[/tex]

[tex]d=\sqrt{53}[/tex]

Therefore, the distance between two points (-5,8) and (-3,1) is [tex]\sqrt{53}[/tex] units.

Answer:

Gabe worked for 6 2/3 hours and Paula worked for 4 hours.

Step-by-step explanation:

It is given that,

Diana worked on her science project for 5 1/3 hours.

Gabe worked on his science project 1 1/4 times as long as Diana.

Paula worked on her science project 3/4 as long as Diana.

Solution,

ATQ,

Gabe worked for :

[tex]5\dfrac{1}{3}\times 1\dfrac{1}{4}\\\\=\dfrac{16}{3}\times \dfrac{5}{4}\\\\=\dfrac{20}{3}\ h\\\\=6\dfrac{2}{3}\ h[/tex]

Pauls worked for :

[tex]\dfrac{3}{4}\times 5\dfrac{1}{3}\\\\=\dfrac{3}{4}\times \dfrac{16}{3}\\\\=4\ h[/tex]

Hence, Gabe worked for 6 2/3 hours and Paula worked for 4 hours.

Answer:

14 degrees.

Step-by-step explanation:

I am assuming that the 56 degree angle is at the centre of the circle.

The angle at the top in the circle = 1/2 * 56 = 28 degrees.

The reflex angle = 360 - 56 = 304 degrees.

If we draw a line from the vertex of the 56 degrees angle to the vertex of 28 degree angle we bisect the reflex angle and the 28  degree angle. Also the 2  triangles formed are congruent ( by SSS).

So x = 180 - 1/2 * 28 - 1/2 * 304

= 180 - 14 - 152

= 180 - 166

= 14 degrees.

Answer:

you might’ve already answered this but it’s 65

Step-by-step explanation:

the two sides in a triangle have to be congruent so if one angle is 65, the other has to be 65 too :)

Answer:

65

Step-by-step explanation:

the given triangle is an isoceles triangle and opposite angles of opposite equal sides of isosceles triangle are equal

Answer:

A. Yes; acute triangle

Step-by-step explanation:

a=6

b=14

c=13

Using Pythagorean theorem-

c^2 = a^2 + b^2

13^2 = 6^2 + 14^2

169 = 36 + 196

169 = 232

169 < 232

Therefore, (a) the triangle is acute.

If 169 =169 there would be a right triangle.

If c were greater than a + b there would be an obtuse triangle.

Answer:when x= -2/3

Answer: 228

Step-by-step explanation:

10% of 380 is 38.

The winning candidate got 60% of the votes.

So, we will multiply 38 by 6.

38 x 6 = 228

The answer to the question is 228.
