Answer:

35°, 55°

Step-by-step explanation:

sin(3x + 2)° = cos(x+44)°

Since sine and cosine are based upon right triangles, the two angles must add up to 90°. Thereby, 3x+2 +  x+44 = 90. Combine like terms to get:

4x + 46  =  90       subtract 46 from both sides

    -46     -46

4x          = 44        divide both sides by 4

4                4

x    =   11          plug that back into both angles

3(11) + 2 = 35;   11 + 44 = 55

Answer:

If we use the variable l for length, then the width is l + 10.

A key phrase is “same perimeter.”

A key word is “equal” when referring to the length of the two shapes.

Step-by-step explanation:

i did the problem on online school

An equation to represent the given situation is 4x+20=5x+50.

Given that, a regular pentagon and a rectangle have the same perimeter.

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Let the length of a rectangle be x.

Then, the width of the rectangle is 10 more than its length be x+10.

The length of the rectangle and the side of the pentagon are equal.

So, the side of the pentagon = x+10

Now, the equation is 2(x+x+10)=5(x+10)

⇒ 2(2x+10)=5(x+10)

⇒ 4x+20=5x+50

Therefore, an equation to represent the given situation is 4x+20=5x+50.

Answer:

9 seconds after the object is launched

Step-by-step explanation:

The function models the height of the object as a function of the time after the object is launched. Therefore h(t) will be zero, and you will solve for t like a normal quadratic equation.

0 = -4t² + 16t + 180

First, you can factor out the -4 from all the terms.

0 = -4(t² - 4t - 45)

Next, factor what is inside the parentheses

0 = -4 (t + 5) (t - 9)

Then you set each of the factors individually to zero and solve

t + 5 = 0 and t - 9 =0

From this we get that time is:

t = -5 and t = 9

Now that time cannot be negative, we figure out that the time is 9 seconds, therefore the object will hit the ground after 9 seconds.

Answer:

So, the GCF of 12x^5 and 8x^3 is 4x^3.

Step-by-step explanation:

To find the greatest common factor (GCF) of 12x^5 and 8x^3, you can break down each term into its prime factors and then identify the common factors:

12x^5 = 2^2 * 3 * x^5

8x^3 = 2^3 * x^3

Now, identify the common factors is this :

The common factor of 2^2 (4) and 2^3 (8) is 2^2 (4).

The common factor of x^5 and x^3 is x^3.

So, the GCF of 12x^5 and 8x^3 is 4x^3.

The GCF of 12x^5 and 8x^3 is 4x^3.

The GCF (Greatest Common Factor) of 12x^5 and 8x^3 can be found by factoring out the common factors of the two terms. In this case, the common factor between the two terms is 4x^3.

To find the GCF, we need to find the highest power of x that can be divided into both terms: 12x^5 and 8x^3. Since 4x^3 is the highest power of x that can be divided into both terms, it is the GCF.

Therefore, the GCF of 12x^5 and 8x^3 is 4x^3.

Answer:

2412 mm³

Step-by-step explanation:

It's two rectangular prisms.

Let's start with the formula for volume --> V = Bh

Top prism

V = Bh

V = (13*12)(12)

V = (156)(12)

V = 1872 mm³

Bottom prism

V = Bh

V = (15*12)(3)

V = (180)(3)

V = 540 mm³

Now add them both together and you get 540 + 1872 = 2412 mm³

The volume of the composite figure shown below is,

⇒ 2412 mm³

A cuboid is the solid shape or three-dimensional shape. A convex polyhedron which is bounded by six rectangular faces with eight vertices and twelve edges is called cuboid.

Given that;

Two rectangular prisms are shown.

Since, The formula for volume of Cuboid is,

⇒ V = Bh

Hence, For Top prism;

V = Bh

V = (13×12)(12)

V = (156)(12)

V = 1872 mm³

And. For Bottom prism;

V = Bh

V = (15×12)(3)

V = (180)(3)

V = 540 mm³

Thus,  The volume of the composite figure shown below is,

⇒ 540 + 1872 = 2412 mm³

Step-by-step explanation:

Explanation of correlation coefficient, its significance in determining relationship strength between variables, and how to interpret its value.

The correlation coefficient provides a measure of how strongly two variables are related in a linear manner. It ranges from -1 to 1, where 1 represents a perfect positive correlation, -1 a perfect negative correlation, and 0 no correlation.

A correlation coefficient close to 1 or -1 indicates a strong relationship, while a coefficient close to 0 indicates a weak or no relationship. This numerical value helps determine how predictable changes in one variable are as the other variable changes.

Interpreting the correlation coefficient assists in understanding the strength and direction of the relationship between variables, aiding in making predictions or drawing conclusions based on the data's patterns.

Answer: B on edg 2020

Step-by-step explanation:

Answer:

A) Mark speed = 7mph  Annie speed is 1.2miles faster at 8.2mph

B) Mark had sailed ratio to Annie 17.5: 20.5

= 3mph faster in 15 minutes This makes it 12mph faster every 5 hrs

The percentage speed of Mark is 83% of 100% of Annie.

This makes Annie 7% faster

7% of 7mph = 1.2 so it has to be 1.2miles faster and not 12mph faster to meet at 15minutes.

Step-by-step explanation:

Annie is 12mph faster they pass 15mins after departure

= 0-15= Annie is 4mp faster than Mark at 15mins.

Annie = 5 miles = m+60m = 60 this makes mark 5.6 : 6 ratio per 15 minutes 28:30 = 1.4 : 1.5 ratio at 15 minutes.

Mark = 5 miles = 5 x 1.4 =7mph + 0m = 7mph

Annie = 5 miles = 5 x 1.5 = 7.5mph + 7 = 8.2mph

A=We can check that 1/4 of 8.2mph distance = 2.5 per 15mins

M=We can check that 1/4 of 7.0mph distance = 1.75 per 15mins

A=We can check that 2.05 per 15mins = 2.5 x 4  = 8.2 mph = 41miles in 5 hr

M=We cna check that 1.75 per 15mins = 1.7 x 4 x 5= 7mph = 35 miles every 5hr

Answer:

I think it is 216 square feet.

Step-by-step explanation:

Formula for surface area is: 2B + Ph (where B is the area of the base, h is the height and P is the perimeter of the base)

2 * 60 + 32 * 3

120 + 96

216 ft

Given:

Sphere and cylinder have same radius and height.

Volume of the cylinder = 48 cm³

To find:

The volume of the sphere.

Solution:

Radius and height of cylinder are equal.

⇒ r = h

Volume of cylinder:

[tex]V=\pi r^2h[/tex]

Substitute the given values.

[tex]48=\pi r^2r[/tex]   (since r = h)

[tex]48=\pi r^3[/tex]

[tex]48=3.14 \times r^3[/tex]

Divide by 3.14 on both sides.

[tex]$\frac{48}{3.14} =\frac{3.14\times r^3}{3.14}[/tex]

[tex]$15.28=r^3[/tex]

Taking cube root on both sides, we get

2.48 = r

The radius of the cylinder is 2.48 cm.

Sphere and cylinder have same radius and height.

Volume of sphere:

[tex]$V=\frac{4}{3} \pi r^3[/tex]

[tex]$V=\frac{4}{3} \times 3.14 \times (2.48)^3[/tex]

[tex]V=63.85[/tex]

The volume of the sphere is 63.85 cm³.

Given:

To find:

The simplified expression.

Solution:

[tex]$\frac{\left(\frac{a^{2}-b^{2}}{a b}\right)}{\left(\frac{1}{b}-\frac{1}{a}\right)}[/tex]

Apply the fraction rule: [tex]\frac{\frac{y}{z}}{x}=\frac{y}{z \cdot x}[/tex]

[tex]$\frac{\left(\frac{a^{2}-b^{2}}{a b}\right)}{\left(\frac{1}{b}-\frac{1}{a}\right)}=\frac{a^{2}-b^{2}}{a b\left(\frac{1}{b}-\frac{1}{a}\right)}[/tex]  ------------ (1)

Let us simplify [tex]\frac{1}{b}-\frac{1}{a}[/tex].

LCM of a and b = ab

Adjacent fraction based on the LCM

[tex]\frac{1}{b}-\frac{1}{a}=\frac{a}{a b}-\frac{b}{a b}[/tex]

         [tex]=\frac{a-b}{a b}[/tex]

Substitute this in equation (1).

         [tex]$=\frac{a^{2}-b^{2}}{\frac{a-b}{a b} a b}[/tex]

Common factor ab get canceled.

         [tex]$=\frac{a^{2}-b^{2}}{a-b}[/tex]

Apply the algebraic formula: [tex]x^{2}-y^{2}=(x+y)(x-y)[/tex]

         [tex]$=\frac{(a+b)(a-b)}{a-b}[/tex]

Cancel the common factor a - b, we get

         [tex]=a+b[/tex]

The simplified expression is a + b.

Step-by-step explanation:

There is a probability of 3.94% that a randomly selected score on the verbal section is higher than 165

The z score is used to show by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean)/standard deviation

Given that mean of 150 and a standard deviation of 8.5. Hence:

For x > 165

z = (165 - 150)/8.5 = 1.76

P(z > 1.76) = 1 - P(z < 1.76) = 1 - 0.9606 = 0.0394

Answer:

Step-by-step explanation:

Consider a segment parallel to CD and passing through B.

This segment will form a right-angle triangle with A

It's length would be equal to the length of CD (the missing length)

Height of that triangle:

11 - 4 = 7

CD² = 16² - 7²

CD² = 207

CD = sqrt(207)

AC² = AD² + CD²

AC² = 11² + 207

AC² = 328

AC = 2sqrt(82)

Which is roughly 18.1 cm
