Find the area of an equilateral triangle with side length 9.2 cm. Round your answer to 1 DP.
Answer:
Area=36.66 cm^2
Step-by-step explanation:
First, you need the height.
Use the Pythagorean theorem:
hypotenuse^2=height^2+(1/2 base)^2
It's one-half base because it's an equilateral triangle.
1/2 base =4.6
(9.2)^2-4.6^2=height^2
84.64-21.16=height^2
height^2=63.48
height=7.97
Area=(1/2)(base)(height)
Area=(1/2)(9.2)(7.97)=36.66 cm^2

Which fraction can be replaced with 1 2 when estimating with fractions? A. 10 12 B. 7 16 C. 2 9 D. 1 8
Answer:
B. 7/16
Step-by-step explanation:
The answer to this question is the option whose value is closest to 1/2.
We know that the fraction 1/2 is 0.5, now we have to get that fraction out of all these fractions that is closest to the value 0.5
10/12 = 0.833
7/16 = 0.43
2/9 = 0.222
1/8 = 0.125
The value closest to 0.5 is obviously 0.43 from the above. Therefore we can conclude that the fraction 7/16 is closets to 1/2 given these other fractions.
Thank you!
Select the three number bonds that represent factor pairs of the number 56. CLEAR CHECK Number bond: 1 times 56 = 56. Number bond: 4 times 14 = 56. Number bond: 5 times 6 = 56. Number bond: 7 times 8 = 56.
Answer:
The answer is -
Number bond: 1 times 56 = 56.
Number bond: 4 times 14 = 56.
Number bond: 7 times 8 = 56.
Step-by-step explanation:
We can define a factor pair as a set of two factors, which, when multiplied together, give a particular product.
For example -
5 and 6 are factors of 30 because 5×6 = 30
Now,
Given -
Number bond: 1 times 56 = 56. ...................(1)
Number bond: 4 times 14 = 56. ...................(2)
Number bond: 5 times 6 = 56. ...................(3)
Number bond: 7 times 8 = 56. ...................(4)
In equation (1)
1 times 56 = 1×56 = 56
⇒1 and 56 are the factor pairs of 56
Satisfies
In equation (2)
4 times 14 = 4×14 = 56
⇒4 and 14 are factor pairs of 56
Satisfies
In equation (3)
5 times 6 = 5×6 = 30 ≠ 56
⇒5 and 6 are not factor pairs of 56
Not Satisfies
In equation (4)
7 times 8 = 7×8 = 56
⇒7 and 8 are factor pairs of 56
Satisfies
∴ we get
The answer is -
Number bond: 1 times 56 = 56.
Number bond: 4 times 14 = 56.
Number bond: 7 times 8 = 56.

9 A rectangle of perimeter 42 cm is
pcm long and q cm broad. If the
difference between the length and
breadth is 9 cm. find
pand q
the area of the rectangle
Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm

El día 12 de diciembre en Moscú se registró una temperatura de 13° bajo cero, a esa misma hora, en buenos Aires hacía una temperatura de 25 grados sobre cero. ¿Qué diferencia térmica existía en ese momento entre las dos ciudades? A.38 B.-38 C.12 D.-12
Answer:
A. [tex]38\ \text{grados}[/tex]
Step-by-step explanation:
La temperatura en Moscú es de 13 grados bajo cero. Entonces, la temperatura es de -13 grados.
La temperatura en Buenos Aires es de 25 grados bajo cero. Entonces, la temperatura es de 25 grados.
La diferencia de temperatura entre las dos ciudades es
[tex]25-(-13)=38\ \text{grados}[/tex]
La diferencia de temperatura entre las dos ciudades en un momento dado es [tex]38\ \text{grados}[/tex].

If m<1=(6x+25), and m<2=(x+5), find m<2
Answer:
Assuming they are equal to each other, X = -4
Step-by-step explanation:
6x + 25 = x + 5
Subtract 5 from both sides
6x + 20 = x
subtract 6x from the left side
20= 5x
divide by 5
-4 = x

80p2 - 180r2
Answer:
80p2 - 180r2
20(4p²-9r²)
20(2p+3r)(2p-3r)
Answer:
20(2p - 3r)(2p + 3r)
Step-by-step explanation:
Given
80p² - 180r² ← factor out 20 from each term
= 20(4p² - 9r²) ← difference of squares which factors in general as
a² - b² = (a - b)(a + b)
4p² - 9r²
= (2p)² - (3r)² ← with a = 2p and b = 3r
= (2p - 3r)(2p + 3r)
Thus
80p² - 180r² = 20(2p - 3r)(2p + 3r) ← in factored form
Which of the following equations could you solve by first adding six and then dividing by negative three?
6 - 3 x = -9
+ 6 = -9
-3 x - 6 = -9
3 x - 6 = -9
Answer:
-3x - 6 = -9 (The third answer)
Step-by-step explanation:
When solving for x, you have to undo each operation. When solving -3x - 6 = -9, you have to undo the -6 first. To do this, add 6 to both sides. Then, you must undo the -3x. To do this, divide by -3 from both sides.
