what is the solution to the equation?
x=3
x=1
x=-1
x=-3

Answer:

95

Step-by-step explanation:

A triangle must always equal 180, so if you take the values of 15 and 70, you get 85.

Then, you take 180 and subtract 85.

This leaves you with 95

Answer:

Option A

Step-by-step explanation:

Use the Pythagoras Theorem

Hypotaneous² = base² + height²

BC² = AB² + AC²

BC = √ (AB² + AC²)

BC =  √ (12² + 16²)

BC = 20

Answer:

20

Step-by-step explanation:

Here's your solution

=> in a right angle traingle

BC^2 = AB^2 + AC^2

=> BC^2 = 16^2 + 12^2

=> BC ^2 = 256 + 144

=> BC^2 = 400

=> BC = √400

=> BC = 20

Answer:

7.25cm

Step-by-step explanation:

Let the complete question be;

Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.

Area of a trapezoid = 1/2(a+b)*h

a and b are the parallel sides (bases)

h is the height

Given

a = 3.5cm

b = 8.5cm

A = 43.5 sq.cm

Required

Height h

Substitute the given values into the expression

Area of a trapezoid = 1/2(a+b)*h

43.5 = 1/2(3.5+8.5)*h

43.5 = 1/2 * 12h

43.5 = 6h

h = 43.5/6

h = 7.25cm

Hence the height is 7.25cm

The scale factor of the model is 0.075.

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.

We are given that Scale model of a building is 12 inches tall. The actual building is 160 feet tall.

First, we need to multiply 160 by 12 so that we have inches and inches

160 inches

Then divide 160 by 12 and that will give, 12 which is the scale factor

Volumen = 0.0010126 m³

Ancho = 7,84 N

Explicación paso a paso:

Dado que:

Masa, m de alcohol = 0,8 kg

Densidad del alcohol, d = 790 kg / m³

Recordar :

Densidad, d = masa, m / volumen, v

Volumen = masa / densidad

Volumen = 0,8 kg / 790 kg / m³

Volumen = 0.0010126 m³

Peso, W = densidad * aceleración debido a la gravedad * volumen

Ancho = 790 * 9,8 * 0,0010126

W = 7.8395

Ancho = 7,84 N

Answer:

For the 1st one: 63

For the second one: 99

Step-by-step explanation:

This is because to find the perimeter, you have to do length+length+width+width=area

So you do 77+77+x+x=280, this should get you x=63

For the second one, to find area you do length×width=area

So you do 59×x=5841 and should get 99.

Answer:

We have given that,

The surface area of a regulation spherical soccer ball is about 484π

square centimeters. If the diameter of the regulation ball is reduced by 50% to produce a new ball.

We have to determine,

The diameter of the new ball, to the nearest tenth of a centimeter.

The volume of a sphere = 4/3 × πr^3.

Therefore we get,

Answer:

42gtt/m

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Flow rate in gtt/min = (Total fluid in ml × Drop factor) ÷ (Total hours × 60)

Where, Total fluid in ml = 2,000ml

Drop factor = 15gtt/m

Total hours = 12hours

By putting the following value in the formula, we get

Flow rate in gtt/min = (2,000 × 15) ÷ (12 × 60)

= 30,000 ÷ 720

= 41.67 or 42gtt/m

what is the shape ?

Answer:

1.x=45,2.x=16

Step-by-step explanation:

1.

x+90+45=180(Angles in an adjacent angle)

x=180-135

x=45

2.

7x=112(vertically opposite angle)

x=112/7

x=16

First question refers to the supplementary angle theorem.

To find x, we need to refer to the other angles around it and use it to subtract it from 180°.

90 + 45 + x = 180

135 + x = 180

x = 180 - 135

x = 45°

Second question refers to the vertical angles theorem, where it states that the angles that face in opposite directions are the same.

7x = 112

x = 112 ÷ 7

x = 16°

Answer:3

Step-by-step explanation:

The 6 fedoras expect if next 30 hats requested from Zoe's inventory, and She recently provided 20 different hats, including 4 fedoras.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The ratio of hats to fedoras = 20:4

Let's suppose Zoe's inventory, should expect to x fedoras

20/4   =  30/x

x = 30/5

x = 6

Thus, the 6 fedoras expect if next 30 hats requested from Zoe's inventory, and She recently provided 20 different hats, including 4 fedoras.
