Answer:

$\sqrt{5}$

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

In this situation a = 1, b = 2

$1^{2} + 2^{2} = c^{2}$

1 + 4 = $c^{2}$

5 = $c^{2}$

c = $\sqrt{5}$

This is an important mathematical theorem to know. It's called the Pythagorean Theorem.

The ratio of sweaters to dresses that Jennifer has is 8:5. If

melomori [17]

Answer:

Ratio of sweaters to dresses = 8 : 5

Sum of ratios = 13

Let number of sweater + dresses = x

$number \ of \ sweaters = \frac{8}{13} *x\\\\24 = \frac{8}{13}*x\\\\x = \frac{24*13}{8} = 3*13 = 39$

$number \ of \ dresses = 39 - 24 = 15$

The sum of the lengths of two opposite sides of the circumscribed quadrilateral is 10 cm, and its area is 12 cm2. Find the radiu

PtichkaEL [24]

Answer:

1.2 cm

Step-by-step explanation:

The area of sircumscribed quadrilateral over a circle is equal to

$A=s\cdot r,$

where s is semi-perimeter of the quadrilateral and r is the radius of the circle.

Use property of circumscribed quadrilateral: The sums of the opposite sides are equal.

So, if the sum of two opposite sides of the circumscribed quadrilateral is 10 cm, then the sum of another two sides is also 10 cm and the perimeter of the quadrilateral is 20 cm. Hence,

$s=\dfrac{20}{2}=10\ cm$

Now,

$A=s\cdot r\\ \\12=10r\\ \\r=\dfrac{12}{10}=1.2\ cm$

What is the blood type of the unknown parent?

Vinil7 [7]

Answer:

IBi0

Step-by-step explanation:

We look at the child's genotype (lAi0).

We know that the blood type's genotype has 2 genes, one from the mother and one from the father.

If the genotype is lAi0 and one gene is, let's say, from mother (lA), we know exactly that the other gene is from father (i0).

So, father's genotype is lBi0 (a).

The box plots show the data distributions for the number of text messages Will and Jaime sent each day.What is the difference of

Softa [21]

Hey there!

You can find the medians by referring to the line in the middle of both of the boxes. These indicate the median of the sets of data you have. The first median is at 10 and the other is at 12.

All you need to do to find the difference is subtract the smaller number from the bigger number.

12 – 10 = 2

Your difference will be 2, making your second option your answer. Hope this helped you out! :-)
