Answer:

q = 0.5 quarts of 100% antifreeze

Step-by-step explanation:

q = quarts of pure antifreeze

 

Set this up as a weighted combination of the mixtures.

 

(100%)(q) + (10%)(4) = (20%)(q + 4)

 

100q + 40 = 20(q + 4)

 

5q + 2 = q + 4

 

4q = 2

 

q = 0.5 quarts of 100% antifreeze

Complete the sentences below the radius of a circle is _____ the length of its diameter. the diameter of a circle is ______ the
son4ous [18]

Answer:

Half;  twice

Step-by-step explanation:

In a circle, the radius is said to be the distance from the center of the circle to any point on the edge of the circle, it is denoted as "r". The radius is called a radii if it is more than one.. The radius of a circle is half the length of the diameter of a circle because the diameter of a circle is the distance of the line that passes through the center of a circle touching both edges of the circle. It is denoted as "d".

Thus,

2r = d

r = d/2

For example, if the radius of a circle is 10cm, the diameter of the circle will be calculated as: d = 2 * 10 = 20cm. Which means if the radius is 10cm, diameter will be 20cm.

Therefore, the radius of a circle is half the length of its diameter. the diameter of a circle is twice the length of its radius

Anyone know the answer?
Gnesinka [82]

Answer:

  2³² -1

Step-by-step explanation:

The sequence has a₁ = 1 and r = 2. Filling in the numbers for n=32, we have ...

S₃₂ = 1·(1 -2³²)/(1 -2)

S₃₂ = 2³² -1

Can someone explain and give me the answers ty
Nataliya [291]

The expression evaluates to 20

We have :   5 |3-7|

We have to evaluate above expression.

<h3>State the property Modulus of the function - F(x) = x.</h3>

For a function f(x) = x, which is real in nature -

f(x) = |x| =  \left \{ {{-x\;\;\;for\;x < 0} \atop {x\;\;\;for\;x > 0}} \right.

The above property is called Modulus property. It is used to find the absolute value or magnitude of a quantity.

In the question it is given -

5 |3-4|

5 |3 - 4|

5 x 4 = 20                    {Using the property of modulus f(x) = - x  for  x < 0}

Hence, the expression evaluates to give an absolute value of 20

BRAINLIEST!!<br><br>5. Rotate the rectangle 180 degree counterclockwise about point T.
m_a_m_a [10]

Answer:

The third option/figure

Step-by-step explanation:

When rotating 180°, you basically reflect the original figure from a slant line that contains the point (T).

We have two options, the first or the third. In logical terms of reflection, third would be the most reasonable one because for instance, point J needs to be pointing directly to point T or else it would result as a translation rather than a rotation.

So the third option is the most reasonable.
