Answer:

B, 114.24

Step-by-step explanation:

The sides of the square = 32 in. Add the flat sides of the quarter circles = another 32 in. = 64in of flat sides

The circumference of the circle, if it was whole, is (2)(pi)(r) = (2)(3.14)(16) = 100.48. We have 2 quarter circles, so we'll cut that answer in half for those arcs. = 50.24in of curved sides.

64 + 50.24 = 114.24, answer B of your choices.

Answer: L 38

Step-by-step explanation:

total 84

Answer: 48 small shirts

108 medium shirts

84 Large shirts

Step-by-step explanation:

20% of 240 = 48

45% pf 240 = 108

45 + 20 = 65, 100 - 65 = 35

35% of 240 = 84

And 48 + 108 + 84 = 240

Answer:

0 Start at the origin. Move 7 units to the right, then move 4 units up.

Step-by-step explanation:

You go in before you go up, the first number always goes either right or left, depending on if it's negative or positive, and the second number goes up or down, depending on if it's negative or positive.

Answer:

2n² + 5n - 102 = 0

n = 6

Step-by-step explanation:

The formula for the area of a rectangle is:

\(\boxed{A=w \cdot l}\)

where w is the width and l is the length.

From inspection of the given rectangle:

Given that the area of the rectangle is 90 cm², then A = 90.

Substitute the values of A, w and l into the formula:

\(\implies 90=(n+4)(2n-3)\)

Switch sides:

\(\implies (n+4)(2n-3)=90\)

Expand the left side of the equation using the FOIL method:

\(\implies 2n^2-3n+8n-12=90\)

\(\implies 2n^2+5n-12=90\)

Subtract 90 from both sides:

\(\implies 2n^2+5n-12-90=90-90\)

\(\implies 2n^2+5n-102=0\)

To solve a quadratic in the form ax² + bx + c, find two numbers that multiply to ac and sum to b.

\(\implies ac=2 \cdot (-102)=-204\)

\(\implies b=5\)

Two numbers that multiply to -204 and sum to 5 are:

Rewrite b as the sum of these two numbers:

\(\implies 2n^2+17n-12n-102=0\)

Factor the first two terms and the last two terms separately:

\(\implies n(2n+17)-6(2n+17)=0\)

Factor out the common term (2n + 17):

\(\implies (n-6)(2n+17)=0\)

Apply the zero-product property:

\((n-6)=0 \implies n=6\)

\((2n+17)=0 \implies n=-8.5\)

n = -8.5 is an extraneous solution since this solution gives negative side lengths, which is impossible.

Therefore, the only valid value of n is n = 6.

\(\hrulefill\)

Check by substituting the found value of n:

\(\textsf{Width}=6+4=10\; \sf cm\)

\(\textsf{Length}=2(6)-3=9\; \sf cm\)

\(\textsf{Area}=10 \cdot 9=90\; \sf cm^2\)

Answer:

x=28

Step-by-step explanation:

6(x+2)=180 Step 1: Write equation

6x+12=180 step 2: Expand the equation

6x=168 Step 3: Do 180-12 first

x=28 Step 4: Divide by 6 answer you got in Step 3

Step 5: replace 28 with x to see if it's correct 6(28+2)= 180

Answer:

65 years old.

Step-by-step explanation:

Define the variables:

Given:

Create two equations with the given information and defined variables:

\(\begin{cases}y = 13x\\y + 1 = 11(x + 1)\end{cases}\)

Substitute the first equation into the second equation and solve for x:

\(\implies 13x+1=11(x+1)\)

\(\implies 13x+1=11x+11\)

\(\implies 2x=10\)

\(\implies x=5\)

Substitute the found value of x into the first equation and solve for y:

\(\implies y=13(5)\)

\(\implies y=65\)

Therefore, the age of the grandparent now is 65 years.

Given statements:

Let us represent the character's age by variables. Assuming that the grandparent's age is G and the granddaughter's age is D. Now, using the obtained variables and the statements, create two equations that represents the provided statements. Then, we can compare the equations and simplify if needed to determine the value of the variables.

    \(\implies \left[\begin{array}{ccc} \text{G = 13D} \\ \text{G + 1 = 11(D + 1)}\\\end{array}\right]\)

Since G = 13D is in the form of direct variation, we can substitute the value of G into the second equation to determine the value of D (the age of the granddaughter). Then, we can substitute the value of D into any of the two equations to determine the age of the grandparent.

To solve for D, simplify both sides of the equation by using the distributive property. We need to simplify both sides of the equation so that we can isolate the variables on the other side of the equation.

Isolate the variables on one side. This step is necessary because it can cancel out the extra variable and simplify the other variable. To do this, you can either add or subtract on both sides of the equation.

Note: I am subtracting 11D on both sides of the equation since it is my preference. But you can also subtract 13D on both sides of the equation.

To further isolate 2D, we need to subtract 1 on both sides of the equation to cancel out the 1 on the left-hand side of the equation. Then, we have:

But the variable is still not completely isolated since there is a coefficient being multiplied to D. To isolate the coefficient from the variable, we will need to divide the coefficient (2) on both sides of the equation.

Then, simplify both sides of the equation. Eventually, we will have a variable on one side and a numerical value on the other side.

Now we know the age of the granddaughter, we can substitute the age of the granddaughter into one of the equations and simplify it to determine the age of the grandparent. I am going to choose G = 13D since it is easier to simplify. Then, we will substitute the value of D into the equation.

Therefore, the age of the grandparent is 65 years.

Answer:

42%

Step-by-step explanation:

I think it's 42% because out of the 57 girls 34 prefer biology,20 prefer chemistry then it means the remaining 3 prefer physics. There's 43 boys, 8 prefer chemistry,27 prefer physics which leaves us with 8 boys who maybe prefer biology. Therefore:

(34+8)÷100×100 = 42%

Answer:

a = (4 - 9b)/2

w = (t - 3)/7

Step-by-step explanation:

2a + 9b = 4

2a= 4 - 9b

a = (4 - 9b)/2

t = 7w + 3

7w = t - 3

w = (t - 3)/7

Answer:

Step-by-step explanation:

The discriminant of this equation, i.e, D=\(b^{2}-4ac\) is less than 0:

D= 0-(4*2*18)   --> which is clearly negative

When D is less than 0, the equation has no real number solutions.

Therefore, \(2x^{2}+18=0\) has no real roots

Answer:

Step-by-step explanation:

0 has no roots so thats one, and im just trying to complete a challenge so sorry if im wrong :( but make other person brainliest they did good job :)

Answer:

y = 2x - 1

Step-by-step explanation:

y = 2x - 1 wouldn't be a proportional relationship. You can tell because any equation with addition or subtraction is not going to be proportional.

Answer:

y=2x-1

Step-by-step explanation:

notice how the second option, y=2x-1 is the only option that has a constant. All other options only have a coefficient on the x term. This makes it perfectly proportional by the factor of the coefficient.

well, if you can go up down and sideways, I'd say, B, F, G, and D

Answer:

x<=3

Step-by-step explanation:

so graphing inequalities on a number line can be tricky but in this case the answer would be x is greater than or equal to three and the reason why is because well first we have the 3 and the circle on the three is filled in meaning the answer of x could possibly be three but the line is also continuing to move to the right therefore meaning the answer could be three but it could also be greater than three therefore your answer is x<=3

Answer:

3(16x+9)/4

make sure it's a fraction

Answer:

27 11/4x

Step-by-step explanation:

First we add the similar parts of the expression.

Whole numbers

6 + 9 + 5 + 7 = 27

Then we add the fractions that dont have x.

We only add the numerators (2 and 3) and dont change the denominators (4)

2/4 + 3/4 = 5/4

Now we add the ones with x.

5/4 + 3/4x + 3/4x = 11/4x

Now we combine those parts together, making

27 11/4x
