We know that water must be three times flour, so our end goal is 12 cups of water, since 4 * 3 = 12.

We already have 2.5 and 4, so we make the equation:

2.5 + x = 12

Simplify.

x = 7.5

Our answer is 7.5

Answer:

68 and 22 degrees

Step-by-step explanation:

Complimentary angles sum to 90

x  +   (x-46) = 90

Answer:

327.5 feet²

Step-by-step explanation:

Let's divide the figure into multiple shapes (Refer to image). To determine the area of the figure, we need to find the area of the divided shapes, then sum it up to obtain the area of the figure.

Determining the area of the triangle:

Given dimensions:

Determining the base of the triangle:

[tex]22 + b + 5 = 7 + 8 + 17[/tex]

[tex]27 + b = 32[/tex]

[tex]b = 32 - 27[/tex]

[tex]b = 5 \ \text{ft}[/tex]

Substituting the base and the height:

[tex]\text{Area of triangle} = \frac{1}{2} \times \text{Base} \times \text{Height}[/tex]

[tex]\text{Area of triangle} = \frac{1}{2} \times 5\times11[/tex]

Simplifying the R.H.S to determine the area:

[tex]\text{Area of triangle} = 5\times5.5[/tex]

[tex]\text{Area of triangle} = 27.5 \ \text{ft}^{2}[/tex]

Determining the area of rectangle₁

Given dimensions:

Substitute the length and the breadth:

[tex]\text{Area of rectangle}_{1}} = LB[/tex]

[tex]\text{Area of rectangle}_{1}} = (5)(17)[/tex]

Simplify the R.H.S to determine the area:

[tex]\text{Area of rectangle}_{1}} = 85 \ \text{feet}[/tex]

Determining the area of rectangle₂

Given dimensions:

Substitute the length and the breadth:

[tex]\text{Area of rectangle}_{2} = LB[/tex]

[tex]\text{Area of rectangle}_{2} = (7 + 5)(8)[/tex]

Simplify the R.H.S to determine the area

[tex]\text{Area of rectangle}_{2} = (7 \times 8) + (5 \times 8)[/tex]

[tex]\text{Area of rectangle}_{2} = 56+ 40[/tex]

[tex]\text{Area of rectangle}_{2} = 96 \ \text{feet}^{2}[/tex]

Determining the area of rectangle₃

Given dimensions:

Substitute the length and the breadth:

[tex]\text{Area of rectangle}_{2} = LB[/tex]

[tex]\text{Area of rectangle}_{2} = (17)(7)[/tex]

Simplify the R.H.S to determing the area:

[tex]\text{Area of rectangle}_{2} = 119\ \text{feet}^{2}[/tex]

Determining the area of the figure:

A (Figure) = A (Triangle) + A (Rectangle₁) + A (Rectangle₂) + A(Rectangle₃)

                 =     27.5 + 85 + 96 + 119

                 =     327.5 feet²

Statement B is True.

C: Base Length = 4.8 ÷ 4 × 3

(a). 5.33 m

(b). 41.65 m²

Answer:

Step-by-step explanation:

The perimeter of an equilateral triangle is:

P = 3a (where a any length of the triangle)

The area of an equilateral triangle is:

[tex]A = \frac{\sqrt{3} }{4} a^{2}[/tex] (where a is the side length)

Using the area formula we can rearrange it to get the formula of the length of the equilateral triangle:

[tex]a = \frac{2}{3} 3^{\frac{3}{4} } \sqrt{A}[/tex]

Then three important formulas are

[tex]\\ \rm\Rrightarrow Perimeter=3s[/tex](As sides are equal)

[tex]\\ \rm\Rrightarrow Area=\dfrac{\sqrt{3}}{4}s^2[/tex]

[tex]\\ \rm\Rrightarrow Height=\dfrac{\sqrt{3}s}{2}[/tex]

Let's check one by one

#1

And

Till now it's ok but

But as B$\cap$ C has no elements this expression yields A$\cap$ C

Hence

#2

Solve RHS

But according to first statement second part has no elements so it yields only

And

It denotes to common elements of A and B not all elements of A

Hence

#3

[tex]\\ \rm\Rrightarrow P(A-B)=32[/tex]

[tex]\\ \rm\Rrightarrow 2^{|A-B|}=32[/tex]

[tex]\\ \rm\Rrightarrow 2^{|A-B|}=2^5[/tex]

[tex]\\ \rm\Rrightarrow |A-B|=5[/tex]

[tex]\\ \rm\Rrightarrow A-B=\pm 5[/tex]

As elements can't be negative integer it's only 5.

[tex]\\ \rm\Rrightarrow A\cap B=A-(A-B)=9-5=4\star[/tex]

And

[tex]\\ \rm\Rrightarrow P(B-A)=16[/tex]

[tex]\\ \rm\Rrightarrow 2^{|B-A|}=16[/tex]

[tex]\\ \rm\Rrightarrow 2^{|B-A|}=2^4[/tex]

[tex]\\ \rm\Rrightarrow |B-A|=4[/tex]

[tex]\\ \rm\Rrightarrow B-A=\pm 4[/tex]

Again take it positive 4

[tex]\\ \rm\Rrightarrow B\cap A=B-(B-A)=7-4=3[/tex]

As

[tex]\\ \rm\Rrightarrow A\cap B\neq B\cap A[/tex]

All statements are incorrect

[tex]b = 2[/tex]

Step-by-step explanation:

[tex]bx= 20[/tex]

insert x=10

[tex]b(10) = 20[/tex]

divide both sides by 10

[tex]b(10) \div 10 = 20 \div 10[/tex]

[tex]b = 20 \div 10[/tex]

simplify

[tex]b = 2[/tex]

The radius of the balloon given the information in the question is 8.98cm.

The first step is to determine the volum of the balloon.

Volume = 81π cm^3 x 12 = 972π cm^3

Now, determine the radius using this formula:

∛[Volume / (4/3π )]

∛[972π cm^3/ (4/3π )] = 8.98cm

Answer:

0.6%

Step-by-step explanation:

40% is the percentange of how many students play an instrument. (the whole) 20% is how many freshmen play. (part)

30% are the freshmen. 30% is over 100%.

20 x 100= 2000 and 40 x 30= 1200.

With the answers we got (2000 and 1200) we divide!!

2000÷1200=0.6

Which means the probabillity that the student is a random freshmen is 0.6% :)

Answer:

He needs to find the area of each lateral face plus the area of the base. The total surface area is 84.

Step-by-step explanation:

area of a triangle= b×h×1/2

therefore area of each triangle(lateral face)= 6×4×1/2= 12

12×4 because there are 4 triangles=48

then the area of the base= 6×6= 36

total surface area= 36+ 48=84

However, this step is not entirely needed in the grand scheme of solving the problem. It simply uses smaller numbers to digest.

Do the opposite of PEMDAS when isolating the variable, d. Note the equal sign, what you do to one side of the equal sign, you do to the other.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)
Multiplication

Division

Addition

Subtraction.

First, subtract 490 from both sides of the equation:

10d + 490 (-490) = 2500 (-490)

10d = 2500 - 490

10d = 2010

Next, divide 10 from both sides of the equation:

(10d)/10 = (2010)/10

d = 2010/10

d = 201

201 is your value for d.

Answer:

There is sufficient evidence to conclude that the distribution of responses is different now than it was historically.

Step-by-step explanation:

Since the p-value is less than the alpha significance level you reject the null hypothesis that the histrocial data matches the current.

We don't have enough evidence to conclude that the distribution of responses is different now than it was historically.

Human resources are the people who make up an organization's, business sector's, industry's, or economy's workforce.

A more specific concept is human capital, which refers to the knowledge and skills that individuals possess.

The chi-square goodness-of-fit test has a p-value of 0.089 at a significance level of 0.10. We cannot reject the null hypothesis because the p-value is greater than 0.10.

As a result, we lack sufficient evidence to conclude that the distribution of responses is different now than it was previously.

"We don't have enough evidence to conclude that the distribution of responses is different now than it was historically," is the correct answer.

Thus, this can be concluded regarding the given scenario.

The sector angle formed by the cone when it is opened is: 54°.

Curved surface area of a cone = πrl, where l is the slant height and r is the radius of the cone.

Area of a sector in a circle = ∅/360 × πr², where ∅ is the sector angle.

Step 1: Find the height (h) of the cone using the volume formula, V= 1/3 x π x r² x h:

V = 95.4 cm³

r = 2.4 cm

Plug in the values:

95.4 = 1/3 x 3.14 x 2.4² x h

95.4 = 6.03 x h

h = 15.8 cm

Step 2: Use the pythagroean theorem to find the slant height (l) of the cone

l = √(h² + r²)

Plug in the values

l = √(15.8² + 2.4²)

l = 16 cm.

Step 3: Find the curved surface area of the cone

Curved surface area = πrl = π(2.4)(16) = 120.6 cm².

Step 4: Find the sector angle of the sector formed by the cone when opened

Curved surface area of the cone = area of the sector formed by the cone = 120.6 cm².

Area of a sector in a circle = ∅/360 × πr², therefore:

120.6 = ∅/360 × (3.14)(16²)

120.6 = ∅/360 × 803.84

(120.6)(360) = (∅)(803.84)

43,416 = (∅)(803.84)

43,416/803.84 = ∅

∅ = 54°

Therefore, the sector angle formed by the cone when it is opened is: 54°.
