Answer:

Please check the explanation.

Step-by-step explanation:

Given

The location of Point A on the number line = -13.4

The location of Point B on the number line = 14

The location of Point C on the number line = 19.9

The location of Point C on the number line = 19.9

Thus, the distance or length between B and C can be calculated by subtracting the point B units from point C units.

BC = 19.9 - 14

= 5.9 units

Therefore,

BC = 5.9 units

Also, the distance or length between C and A can be calculated by subtracting the point C units from point A units.

CA = -13.4-19.9

= -33.3 units

Therefore,

CA = -33.3 units

As the length or distance can not be negative, hence

CA = 33.3 units

Mr polandski is adding food coloring to water to create his own paint colors.he has 5 1/3 cups of water to create a color he nee

vesna_86 [32]

To solve the number of paint color he can make if he utilize all his water, first convert the mix fraction into improper fraction
5 1/3 = 15/3 + 1/3 
= 16/3 cups of water
Divide it by 2/3 cup
Number of color = ( 16/3) / (2/3) 
= 8 paint colors

QRST is a square. PQ = 2√ RU = 4 What is the length of SU? Round to the nearest tenth.

777dan777 [17]

Answer:

$SU=3.5\ units$

Step-by-step explanation:

step 1

In the isosceles right triangle PQT

PQ=PT ----> because is an isosceles triangle

Applying the Pythagoras Theorem

we have

$PQ=PT =\sqrt{2}\ units$

$QT^{2}=PQ^{2} +PT^{2}$

substitute the values

$QT^{2}=\sqrt{2}^{2} +\sqrt{2}^{2}$

$QT^{2}=4$

$QT=2\ units$

step 2

In the square QRST

$RS=QT=2\ units$

step 3

In the right triangle RSU

Applying the Pythagoras Theorem

$RU^{2}=RS^{2} +SU^{2}$

we have

$RU=4\ units$

$RS=2\ units$

substitute the values and solve for SU

$4^{2}=2^{2} +SU^{2}$

$SU^{2}=4^{2}-2^{2}$

$SU^{2}=12$

$SU=2\sqrt{3}\ units$

$SU=3.5\ units$

Plz, answer this it is really easy.

dimulka [17.4K]

Answer:

v = 17.4 meters

Step-by-step explanation:

This is a triangle with height (red dotted line) given.

The area of a triangle is given by the formula:

$A=\frac{1}{2}bh$

Where

A is the area

b is the base length

h is the height

Given height = 12, and

area = 104.4

THe base is labeled as "v", so we find v by replacing into formula:

$A=\frac{1}{2}bh\\104.4=\frac{1}{2}(v)(12)\\104.4=6v\\v=\frac{104.4}{6}\\v=17.4$

The base, v, is 17.4 meters
