Answer:

$a=\sqrt{33}$

Step-by-step explanation:

The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.

a² = 7² -4²

a² = 49 -16 = 33

a = √33

If angle symbol1 and angle symbol2 are complementary angles and if the measure of angle symbol1 is 5454degrees° more than the me

Misha Larkins [42]

<span>Complementary angles by definition sum up to 90 degrees.
Let x = measure of angle2.
It's given that angle1 = x + 54

Since complementary, we know (x+54)+x = 90
2x+54=90
2x=36
x=18.
So angle2 measures 18 degrees and angle1 is 18 degrees+54 degrees, or 72 degrees. 72+18 = 90 as expected for complementary angles.</span>

Paladinen [302]

$\text{Area of the triangle = 6 unit}^2$ Explanation:

The triangle is right angled.

The formula for area of the triangle:

$\begin{gathered} A\text{ = }\frac{1}{2}bh \\ \\ b\text{ = base} \\ h\text{ = height} \end{gathered}$

base = 3

height = 4

substitute the values:

$\begin{gathered} \text{Area of the triangle = }\frac{1}{2}\times3\times4\text{ = 12/2} \\ \text{Area of the triangle = 6 unit}^2 \end{gathered}$

Jared has a wooden board that is 11 ft long. He wants to cut it into 2 pieces so that the longer piece is 4 ft less than 4 times

Kaylis [27]

X+y=11

x is longer than y
x>y
x is 4 less than 4 times y
x=-4+4y

sub back
x+y=11
-4+4y+y=11
-4+5y=11
add 4 to both sides
5y=15
divide both sides by 5
y=3

sub back
x=-4+4y
x=-4+4(3)
x=-4+12
x=8

the pieces are 8ft and 3ft

The formula F = 1.8C + 32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There

11Alexandr11 [23.1K]

Answer:

-40 °F = -40 °C

Step-by-step explanation:

(1) F = 1.8 C + 32

If the Fahrenheit and Celsius temperatures are the same, then

(2) F = C Substitute (2) into (1)

C = 1.8C + 32 Subtract 1.8 C from each side

C – 1.8 C = 32 Combine like terms

-0.8C = 32 Divide each side by -0.8

C = -32/0.8

(3) C = -40 Substitute (3) into (1)

F = 1.8(-40) + 32

F = -72 + 32

F = -40

So, -40 °F = -40 °C

The thermometer below shows that -40 °F = -40 °C.
