Help please! I need the area of this given figure. The formula is A=1/2(b1+b2)h

1:2

Looking at the image, there are 2 grey squares and 1 black square. Since the question is asking how many black squares to grey squares, it would be a 1:2.

Answer:

Step-by-step explanation:

ΔEFG is an isosceles triangle. So, the angles opposite to equal side will be congruent.    {Isosceles triangle property}

x = 46°

ΔEHG , two angles are equal. So, it is an isosceles triangle.

Sides opposite to equal angles are congruent. {Converse isosceles triangle property}

y = GH

y = 8

Answer:

[tex]y = \frac{ - 3}{4} x + \frac{3}{2} \\ y = \frac{4}{3} x + 2 \\ y = \frac{3}{4} x - \frac{3}{2} \\ y = \frac{ - 4}{3} x - 2[/tex]

Step-by-step explanation:

Please see the attachment.

If by "long leg lengths" you mean the hypotenuse then the area is 116 sq. units.  If you mean the bases of the triangles then the area is 170 sq. units.

If the length of 12 is the hypotenuse, we first must find the base of the triangles using the Pythagorean theorem:

10² + b² = 12²

100 + b² = 144

b² = 44

b = √44 = 6.6

This means we have two triangles and a rectangle.  The area of the rectangle is 5(10) = 50 sq. units.  The area of each triangle is 1/2(6.6)(10) = 33.  Adding all 3 together we have:

50+33+33 = 116 sq. units.

If the 12 is the base, then we have the rectangle with the area of 5(10) = 50 and two triangles each with an area of 1/2(12)(10) = 60:

50+60+60 = 170 sq. units.

Answer: 8/3 or 2 2/3

Answer: 2210.6

Step-by-step explanation:

[tex]V=\pi (8)^{2} \cdot 11 \approx 3.14 \cdot 8^{2} \cdot 11 \approx 2210.6[/tex]

Step-by-step explanation:

h²=o²+a²

a²=8²+5²

a²=64+25

a²=89

a=√89

a=9.433

To one decimal place it is 9.4

for b,

h²=o²+a²

17²=b²+12²

289=b²+144

289-144=b²

145=b²

b=√145

b=12.041

To one decimal place it is 12.0

Step-by-step explanation:

I have no clue what the step by step explanation i looked it up

0.48

Step-by-step explanation:

to increase an amount by 48%

you divide 48 with 100 to find the multiplier

which is 0.48

multiply 0.48 to an number to find 48%

Answer:

The answer is 0.372 because you jus dividing it by 10 jus like 0.372 x 10= 3.72 you jus putting the 0 first when dividing .

Answer:

[tex](1, 2)[/tex]

Step-by-step explanation:

We can solve this system using substitution.

In this case, we can substitute 7-3y for x, as they are of equal value.

Therefore...

[tex]2x-3y=-4\\2(7-3y)-3y=-4\\14-6y-3y=-4\\14-9y=-4[/tex]

Subtract 14 from both sides:

[tex]-9y=-18[/tex]

Divide both sides by -9

[tex]y=2[/tex]

Now, substitute 2 for y to solve for x:

[tex]x=7-3y=7-3(2)=7-6=1[/tex]

Therefore the solution to this system of equations is:

[tex](x, y)=(1, 2)[/tex]

[tex] { (x - 5) }^{2} = {x}^{2} - 10x + 25[/tex]

Answer:

52

Step-by-step explanation:

The triangle is 180o

if B and C are 56 and 72

that means 56 + 72 = 128

so B + C = 128

and finally

180 - 128 = 52

A = 52

Answer: A= 52

Answer:

B.

Step-by-step explanation:

4² + 12² = c²

16 + 144 = c²

160 = c²

√160

:)

Answer:

[tex]c=\sqrt{160}[/tex]

Step-by-step explanation:

Pythagorean theory formula:-

[tex]a^2+b^2=c^2[/tex]

Where..

a= 4, b= 12, c= x

[tex]4^2+12^2=x^2[/tex]

[tex]16+144=x^2[/tex]

[tex]160=x^2[/tex]

[tex]\sqrt{160}=\sqrt{x^2}[/tex]

[tex]x=\sqrt{160}[/tex]

Answer:

  47.4%

Step-by-step explanation:

The total amount Louise spent on Frappuccinos was 4×$4.50 = $18. The fraction that is of the total is ...

  Fraps/Total = $18/$38 = 9/19

That can be converted to a percentage by multiplying by 100%:

  9/19 = (9/19)×100% ≈ 47.4%

Louise spent 47.4% of the $38 on Frappuccinos.

Additional comment

The decimal equivalent of 9/19 is a repeating decimal with an 18-digit repeat.

Answer:

y=4x+7

Step-by-step explanation:

Answer:

Step-by-step explanation:

Substituting the given table values into the desired equation for a line will give two equations in two unknowns. These can be solved for the slope and y-intercept.

Equation we're substituting into:

  y = mx +b

  11 = m(1) +b . . . . . substitute (x, y) = (1, 11)

  15 = m(2) +b . . . . substitute (x, y) = (2, 15)

Subtracting the first equation from the second gives ...

  (15) -(11) = (2m +b) -(m +b)

  4 = m

Substituting this into the first equation gives ...

  11 = 4 +b

  7 = b . . . . . subtract 4

The slope is 4; the y-intercept is 7.
