Answer:

8 1/2 cups

Step-by-step explanation:

Add the blue and red cups of paint together to get 8 1/2 cups of paint.

Since we can assume she has enough, the answer is eight and a half cups of purple paint.

Alma can make 20 cups of purple paint.

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here: For every 5 cups of purple paint alma needs to add 1/2 cup of white paint .

Thus with 2 cups white paint she could make 4 batches of 5 cups of purple paint.

Therefore, total number of purple paint cups from 2 cups of white paint is

4×5=20 cupa

Hence, Alma can make 20 cups of purple paint.

Answer:

○ [tex]\displaystyle -6x^2 + 6x + 5[/tex]

Step-by-step explanation:

Since the divisor is in the form of [tex]\displaystyle x - c,[/tex]use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so do not forget it. Anyway, here is how it is done:

2| −6 18 −7 −10

↓ −12 12 10

________________

−6 6 5 0 [tex]\displaystyle \hookrightarrow -6x^2 + 6x + 5[/tex]

You start by placing the c in the top left corner, then list all the coefficients of your dividend [−6x³ + 18x² - 7x - 10]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that −6 in your quotient can be a [tex]\displaystyle -6x^2,[/tex]the [tex]\displaystyle 6x[/tex]follows right behind it, then you end it off with [tex]\displaystyle 5,[/tex]giving you the quotient of [tex]\displaystyle -6x^2 + 6x + 5.[/tex]

Step-by-step explanation:

The mean is just the average Add all individual numbers together then divide by how many numbers you added.

Step-by-step explanation:

l = length

w = width

l = 3w

perimeter p = 2l + 2w = 56

using the identity of the first equation

p = 2(3w) + 2w = 56

6w + 2w = 56

8w = 56

w = 7 cm

l = 3w = 3×7 = 21 cm

so, the area is

l×w = 21×7 = 147 cm²

The perimeter of the rectangle is the length of the boundary of the perimeter of the rectangle. The perimeter of the rectangle is 2(√29+√10).

The perimeter of the rectangle is the length of the boundary of the perimeter of the rectangle.

In order to find the perimeter of the rectangle, we need to find the third side(Hypotenuse) of each triangle, therefore,

In ΔA,

[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]

[tex]GF^2 = 3^2+1^2\\GF=\sqrt{10}[/tex]

In ΔB,

[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]

[tex]EF^2 = 2^2+5^2\\EF=\sqrt{29}[/tex]

In ΔC,

[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]

[tex]GH^2 = 2^2+5^2\\GH=\sqrt{29}[/tex]

In ΔD,

[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]

[tex]EH^2 = 3^2+1^2\\EH=\sqrt{10}[/tex]

Now, the perimeter of the rectangle is,

[tex]Perimeter\ EFGH = EF+ GF + GH +EH[/tex]

                              [tex]=\sqrt{29}+\sqrt{10}+\sqrt{29}+\sqrt{10}\\\\=2\sqrt{29}+2\sqrt{10}\\\\=2(\sqrt{29}+\sqrt{10})[/tex]    

hence, the perimeter of the rectangle is 2(√29+√10).

Answer:

D. (The one with a graph and line)

You can use the vertical line test.

The inequalities are option B, C and D which are;

B. 11 > (w - 4)²         C. y < 3⁴           D. 5+9 < 5×9

Imbalances are numerical articulations that think about two qualities and express that they are not equivalent.

The inequalities are:

B. 11 > (w - 4)²

C. y < 3⁴

D. (5+9) < (5×9)

Here, option A and E are not inequalities. A is a quadratic expression and E is a rational function.

Inequality B says that 11 is greater than the square of the difference between w and 4.

⇒ √(11) > (w - 4)

⇒ w - 4 < √(11) or w - 4 > -√(11)

⇒ w < 4 + √(11) or w > 4 - √(11)

So the solution for inequality B is: w < 4 + √(11) or w > 4 - √(11)

Inequality C says that y is less than 3 to the fourth power (81).

⇒ y < 81

Inequality D says that the sum of 5 and 9 is less than the product of 5 and 9. This is clearly true:

⇒ (5 + 9) < (5 × 9)

⇒ 14 < 45

So the solution for inequality D is: 14 < 45

By Using the Empirical formula we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

According to the empirical rule :

(1)   68% of the measures should come within 1 standard deviation of the mean.

(2   95% of the measures should come within 2 standard deviations of the mean.

(3)  99.7% of the measures should come within 3 standard deviations of the mean.

So we can see in this problem

The mean is 7 inches.

The standard deviation is 1.2 inches.

4.6 = 7 - 2(1.2)

9.4 = 7 + 2(1.2)

The measures are within 2 standard deviations of the mean, hence, 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

Thus by using the Empirical Rule we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

Step-by-step explanation:

Answer:

length= 108 feet,

width= 50 feet

Overview of steps:

Working:

Let the length and the width of the rectangle be L and W feet respectively.

L= 2W +8 -----(1)

Perimeter= 2(length) +2(width)

316= 2L +2W

2L +2W= 316

Divide both sides by 2:

L +W= 158 -----(2)

Substitute (1) into (2):

2W +8 +W= 158

Simplify:

3W +8= 158

3W= 158 -8

3W= 150

Divide both sides by 3:

W= 150 ÷3

W= 50

Substitute W= 50 into (1):

L= 2(50) +8

L= 100 +8

L= 108

Thus, the rectangle's length is 108 feet, and its width is 50 feet.

The measure of the angle formed by the two laser beams is 20°

An angle is formed when two or more lines intersect. Acute angles are angles less than 90 degrees, obtuse angles are greater than 90 degrees while right angles are 90 degrees.

The arc intercepted by the lasers closest to the source measures 60. The arc intercepted by the lasers on the other side of the cylinder measures 80. Hence:

The measure of the angle formed by the two laser beams = 80 - 60 = 20°

Answer:

x is 62 degrees i think

Step-by-step explanation:

wow how do i know how to do this. ANYWAYS:

since it says that the whole two angels is 152 and that one of the angles is 90 degrees we can write the equation:

90 + x = 152

x = 62

you may ask "but thats the degree of the angle next to 90.." but it is also x because it is parallel (i think thats the word)

Answer:

Step-by-step explanation:

Equation of blue line:

blue line is parallel to y-axis

⇒ x = 5

Equation of green line:

Green line is parallel to x-axis.

y = 2

Equation of red line:

At y-intercept x = 0. Point on red line is (0,5)

So, y-intercept = 5

y = mx + b Here,  m is slope any b is y-intercept.

y = mx + 5

Now, choose any other point in red line. ((1,7)

Substitute this value in the above equation and we can find m

7 = m*1 + 5

7 - 5 = m

m = 2

y = 2x + 5

Equation of black line:

Black line and red line are parallel and so, they have same slope.

y = 2x + b

y-intercept (0,-6) ; b = -6

y = 2x - 6
