Answer:
154
113.04 in
Step-by-step explanation:
Area of a circle = Tr²
Circumference of a circle = 2Tr
T = 3.14
r = radius
The radius has to be determined to calculate the area of the circle
43.96 in = 2 x r x 3.14
r = 43.96 in / 2 x 3.14
= 7 in
Area = 3.14 x 7² = 153.86 in = 154 in²

Write the subtraction sentence that is shown on the number line. Do not reduce the fractions.
Answer:
15/8 - 6/8= 9/8
Step-by-step explanation:
We get [tex]\frac{3}{4}[/tex] when we subtract [tex]\frac{4.5}{4}[/tex] from [tex]\frac{7.5}{4}[/tex].
What is subtraction?
Subtraction is a operation of taking the difference of two numbers.
According to the given question
We have a number line in which two numbers are indicated.
The one just after [tex]\frac{4}{4}[/tex] and the another one is after [tex]\frac{7}{4}[/tex].
So the number after [tex]\frac{4}{4}[/tex] is [tex]\frac{4.5}{4}[/tex] and the number after [tex]\frac{7}{4}[/tex] is [tex]\frac{7.5}{4}[/tex]
so, [tex]\frac{7.5}{4} -\frac{4.5}{4} =\frac{3}{4}[/tex]
Hence, we get [tex]\frac{3}{4}[/tex] when we subtract [tex]\frac{4.5}{4}[/tex] from [tex]\frac{7.5}{4}[/tex].

in the diagram below,the angle of depression from P to Q is 45.which of the following is closest to the distance between P and Q
Using relations in a right triangle, it is found that the distance between Q and T is given by:
[tex]h = 32\sqrt{2}[/tex]
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.Researching the problem on the internet, it is found that:
The side opposite to the angle of 45º is of 32 feet.The hypotenuse is the distance between P and Q.Hence:
[tex]\sin{45^\circ} = \frac{32}{h}[/tex]
[tex]\frac{\sqrt{2}}{2} = \frac{32}{h}[/tex]
[tex]h = \frac{64}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}}[/tex]
[tex]h = 32\sqrt{2}[/tex]

.1325 to thousandths
Answer:
.133
Step-by-step explanation:
1 is in the tenths place
3 is in the hundredths place and
2 is in the thousandths place
when given at what place to be rounded to the answer should reflect the numbers to the thousandth place
so look to the right 5 or more add one to the left number
5 or less leave the number in the thousandths place as is
00000.1325
Step-by-step explanation:
Since rounding numbers dealso with real numbers or figures, .1325 will be represented as 0.1325 and it deals with numbers before the decimal which we also called significant numbers. those after are not significant.
So therefore in relation to this; 0.1325 the decimal will be moved three times to the left because thousands means there zeros. the result will be 0000.1325

Rigoberto tiene una finca 36 decámetros cuadrados y las quiero repartir entre sus tres hijos si hay mayor le deja la mitad de la finca y al menos le corresponde a la tercera parte de la mitad de la finca indica cuántos hectómetros cuadrados le corresponde al hijo mayor cuántos metros puedo le corresponde al segundo hijo y cuántos centímetros le corresponde al hijo menor
Answer:
Al hijo mayor le corresonden 0,18 Hm²
Al segundo hijo le corresponden 1200 m²
Al hijo menor le corresonden 6000000 cm²
Step-by-step explanation:
Al hijo mayor le corresponden 18 Dm² la mitad de la finca
En Hm² sn 18 /100 0,18 Hm²
Al hijo menor le corresponden 1/3 de la mitad de la finca (18 Dm²)
es decir 1/3 * 18 Dm² 6 Dm²
en m² serán 6 * 100 = 600 M²
y en cm² 600 * 10000 = 6000000 cm²
Al segundo hijo le corresponden 2/3 de la mitad es decir
2/3 * 18 = 12 Dm² o 12 * 100 = 1200 m²

57,76,95
18,80,82
9,24,26
15,36,39
9514 1404 393
Answer:
(c) 9, 24, 26
Step-by-step explanation:
If you're familiar with Pythagorean triples, you may recognize that 10-24-26 is a doubling of the common 5-12-13 triple seen in many problems. That means the triple 9-24-26 cannot be a right triangle.
__
The "form factor" of f = a^2 +b^2 -c^2, where c is the longest side length, can signal the kind of triangle it is. f=0 indicates a right triangle (values satisfy the Pythagorean theorem). When there are a lot of numbers to try, I like to let a calculator or spreadsheet do the math. (See attached).
As indicated above, the 9-24-26 triple cannot be a right triangle. For f < 0, it will be an obtuse triangle.

Answer:
240
Step-by-step explanation:
1. Area of two small triangles (OR one big) + Area of rectangle
2. Triangle
A(t) = 4*10 = 40 [4*10/2 + 4*10/2]
3. Rectangle
A(r) = 20*10 = 200
4. Combined Area
40+200=240
Step-by-step explanation:
So this figure has two parts:- A triangle and a rectangle
We can first solve area of Triangle
[tex] = \frac{1}{2} bh[/tex]
So the base is 20 and height is 4
[tex] \frac{1}{2} \times 20 \times 4 \\ = 10 \times 4 \\ = 40[/tex]
Now the area of rectangle
[tex] = l \times b[/tex]
Length is 20 and breadth is 10
[tex]l \times b \\ 20 \times 10 \\ = 200[/tex]
So the total area is 200 + 40 which is equal to 240
