find the area for this figure

Answer:

(x + y)² = 25

Step-by-step explanation:

The expansion of (x + y)² is

(x + y)² = x² + y² + 2xy ← substitute x² + y² = 15 and xy = 5

           = 15 + 2(5)

           = 15 + 10

           = 25

Answer:

471 cm

Step-by-step explanation:

here diameter of the circle is 150cm, and we know radius is half of diameter.

therefore r = 150/2

= 75

Now,

according to formula,

Circumference of circle = 2πr

= 2 x 3.14 x 75

= 471 cm

Answer: Vertex = (-1, 5) x-intercepts = No real solutions

Step-by-step explanation:

Vertex = -2/2= -1

-1^2 + 2(-1) +6

1 -2 +6

-1 +6

=5

Discrminats= 2^2 -4(1)(6)

4 -4(1)(6)

4-24

= -20 (It's a negative so there's no real solutions, meaning there's no xintercepts/R0XS)

Answer:

AB/ PQ = BC/QR

Step-by-step explanation:

In similar triangles, ratio of corresponding sides are equal.

So, [tex]\frac{AB}{PQ}= \frac{BC}{QR}=\frac{AC}{PR}[/tex]

Answer:

the radius is 3 m

Step-by-step explanation:

the radius of a circle is always one half of the diameter.

Here the diameter is 6 m, so the radius is 3 m.

Answer:

rhombus

Step-by-step explanation:

Answer:

17/100×15.30=2.60

9/100×15.30=1.37

15.30-(1.37+2.60)=11.33

Answer:

D) 4/5 that's the answer

Explanation:

The rule says "whatever x is, add 1 to it to get y"

So for instance, if x = 3, then y = x+1 = 3+1 = 4

Now if x = 7, then y = x+1 = 7+1 = 8

Answer:

[tex]\huge\boxed{Answer\hookleftarrow}[/tex]

Given that,

[tex]1 + 1 = 2 \\ 2 + 1 = 3 \\ 3 + 1 = 4 \\ 4 + 1 = 5...[/tex]

So from this we can infer that, [tex]\large\bold{ x + 1 = y}[/tex]

Now,

[tex]x = 7 \\ y= \: ?[/tex]

Use the rule ⎆ [tex]\large\bold{ x + 1 = y}[/tex]

[tex]x + 1 = y \\ 7 + 1 = y \\ 8 = y[/tex]

✐ The value of y is 8.

Answer:

Sorry, the dimensions you gave are indecipherable.

Step-by-step explanation:

Answer:

men=150

women=250

total=400

Step-by-step explanation:

a) fraction of men

men/total=150/400=15/40

men/total =3/8

b)let married be x

so unmarried wil be 250-x

married/unmarried=3/2

x / 250-x =3/2

x =3(250-x)/2

2x =750-3x

5x=750

x=750/5

x =150

married =150

unmarried=250-150=100

c)20% of men will be :20x150

100

: 30

no of men =150+20%

=150+30

=180

d)no. of women decreased=250-60

=190

percentage of women leaved=% x 250

100

190x100/250=%

76 =%

76% women leaved

It took too much time

MARK ME BRAINLIEST THANKS MY ANSWER PLEASE

DO FOLOW

Answer:

It's definitely not the first one or the second one, not sure about the third one but the last one is equivalent to it.

3/4 x . 8 = 6

2-1=1

Answer:

< B = 180-30-65=85°

< E = 85°

< D = 30°

< C = 65°

BC = 20/35 × 28 = 16

Answer:

(-∞, -1]∪{5}

Step-by-step explanation:

We know that:

f(x) ≤ 0 is true if the graph of the function is intersecting the x-axis or below the x-axis.

So we can just look at the graph, we can see that in the interval:

(-∞, -1]   (the value x = -1 is included, that is why we use the symbol ] instead of the parenthesis)

the graph is below or intersecting the x-axis

and this also happens at x = 5 or just denoted as {5}

Then the correct notation is:

(-∞, -1]∪{5}

Answer:

x = ± 2

Step-by-step explanation:

To find the x- intercepts let y = 0 , that is

4x² - 16 = 0 (add 16 to both sides )

4x² = 16 ( divide both sides by 4 )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

The x- intercepts are x = - 2 and x = 2

Answer:

y = 8

Step-by-step explanation:

cos = adj/hyp

cos30 = 4√3 / y

y = 4√3 / cos30

y = 6.928203230275509 / 0.866025403784439

y = 8

Step-by-step explanation:

1. I estimate that the error in measuring the area of the lot is about 10% so we write the area as 400 sq ft +- 10%, which means that the lot can be as small as 360 sq ft or as large as 440 sq ft. We tack on 15% more on the number of pieces of sod to account of the plot's irregularities. Since each piece of sod is 2 sq ft, the number of pieces we must get is 440/2 = 220 pieces +- 15% or 253 pieces

2. The nominal value is jus the average weight which is 59.5 g. The tolerance is (3.5g/59.5g)×100% = 5.88% and the measurement range is from 56g to 63g.

Answer:

122 in²

Step-by-step explanation:

Applying,

S.A =  bh+ bl+bl+bl............. Equation 1

Where S.A = Surface area of the prism, b = base of the triangle, h = height of the triangle, l = lenghth of the prism

From the question,

Given: b = 4 in, h = 3.5 in, l = 9 in

Substitute these values into equation 1

S.A = 4×3.5+9×4+9×4+9×4

S.A = 14+108

S.A = 122 in²

Hence the surface area of the prism is 122 in²

Answer:

m less than or equal to 50

Step-by-step explanation:

300 minus 250 is the money that shonte is willing to spend, 50 dollars. Shonte can spend less than 50 because she wants At Least 250 dollars left. So M would be equal to or less than 50.

Answer:

10.1

Step-by-step explanation:

nearest possible answer

Answer:

AC=10.1

Step-by-step explanation:

2accosB=a²+c²-b²

2×7×13cos 50=7²+13²-AC²

182cos50=49+169-AC²

AC²=218-182 cos50

AC=√(218-182 cos 50)≈10.0505≈10.1

Angle LJK = 75 degrees

Step-by-step explanation:

Here, we want to fill the boxes

From the diagram;

angle HJL and LJK are supplementary (they add up to 180 degrees)

Angle HJL + Angle LJK = 180

angle LJK = 180-105

Angle LJK = 75 degrees
