Habib is making some scones.
His recipe tells him to bake the scones at 356°F for 30 minutes.
The temperature gauge on Habib's oven shows the temperature in
degrees Celsius, "C.
The formula to convert °F (Fahrenheit) into °C is:
C = 5F - 160
At what temperature, in °C, should Habib bake his scones?​

Answers

Answer:

1620°C

Step-by-step explanation:

Using the equation

C = 5F - 160, at 356°F we'll have

C = 5(356) - 160

C = 1780 - 160

C = 1620°C

A mirror should be centered on a wall the mirror is 4 feet wide in the wall is 20 Feet wide what equation helps determine the distance X on each side of the mirror

Answers

Answer:

A)x + 4 + x = 20

Step-by-step explanation:

Complete question:

Which equation helps determine the distance x on each side of the mirror?

A. x + 4 + x = 20

B. 4 + x + 4 = 20

C. x = 20 + 4 + 4

D. 4 = 20 + x + x

SOLUTION:

As given,The mirror is 4 feet wide and the wall is 20 feet wide.

The distance 'x' on each side of the mirror is x + x

4 feet wide + x + x = 20 feet wide

The mirror 4 feet wide + the distance x on each side of the mirror = the wall is 20 feet wide

Therefore, the correct option is A

Theater a sells popcorn in a rectangular prism theater B sells popcorn in a similar tub both cost five dollars which theater gives you a better deal find the volume of theater is popcorn

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the dimensions of tubs used by theatre A and B is missing.

However, I'll solve the question as follows.

First, it should be noted that the tub with highest volume gives the best deal.

This is so because both pop corns go for the same price of $5 and the tub with the highest volume contains more popcorn.

The volume of a rectangular prism is calculated by

Volume = Length * Breadth * Height

Take for instance, the dimension of tub A is length = 4cm, breadth = 5cm and height = 6cm

And the dimension of tub B is length = 3cm, breadth = 7cm and height = 5cm

The volume of tub A (theatre A) = 4cm * 5cm * 6cm

Volume = 120cm³

The volume of tub B (theatre B) = 3cm * 7cm * 5cm

Volume = 105cm³

Because the volume of tub A is greater than that of tube B, then tube A offers the best deal

If you apply this steps in your question, you'll arrive at the right answer.

Step-by-step explanation:

[tex] \frac{y1 - y2}{x1 - x2} \\ \frac{7 - ( - 6)}{ - 3 - 2} \\ \frac{7 + 6}{ - 5} \\ = \frac{13}{ - 5} [/tex]

Answer:

-2.6

Step-by-step explanation:

Slope or gradient is the ratio of the vertical (y axis) and horizontal distances (x axis) between two points on a line.

It should be noted that it is defined as zero if the line is horizontal, but undefined if it is vertical.

Given:

Coordinates (- 3, 7) (2, - 6)

y1 = 7, y2= -6, x1= -3, x2=2

Slope : ∆ y/ ∆ x

= (y2 - y1 )/ (x2 - x1)

= (-6 - (7))/ (2 - (-3))

Let be an angle in quadrant such that.
Find the exact values of and.

Answers

Answer:

see explanation

Step-by-step explanation:

Since Θ is an angle in the third quadrant, then secΘ < 0 and tanΘ > 0

Using the identity

sec x = [tex]\frac{1}{cosx}[/tex] , then

cos x = - [tex]\sqrt{1-sin^2x}[/tex]

         = - [tex]\sqrt{1-(-3/5)^2}[/tex] = - [tex]\sqrt{1-\frac{9}{25} }[/tex] = - [tex]\sqrt{\frac{16}{25} }[/tex] = - [tex]\frac{4}{5}[/tex], thus

secΘ = [tex]\frac{1}{-\frac{4}{5} }[/tex] = - [tex]\frac{5}{4}[/tex]

---------------------------

Using the identity

tan x = [tex]\frac{sinx}{cosx}[/tex] , then

tanΘ = [tex]\frac{-\frac{3}{5} }{-\frac{4}{5} }[/tex] = - [tex]\frac{3}{5}[/tex] × - [tex]\frac{5}{4}[/tex] = [tex]\frac{3}{4}[/tex]

The value of sec(x) is (5/4) and tan(x) will be (-3)(4).

What is trigonometry?

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.

Sine, cosine, tangent, cosecant, secant, and cotangent are some of their names. The adjacent side, opposite side, and hypotenuse side of the right triangle are used to define each of these trigonometric ratios.

The six trigonometric ratios are the source of all fundamental trigonometric identities.

The given value of sin (x) is ( -3 / 5 ). The values of sec(x) and tan(x) will be calculated as below:-

sec(x) = 1 / cos(x)

[tex]cosx = \sqrt{1-sin^2x}[/tex]

[tex]cosx = \sqrt{1-(\dfrac{-3}{5})^2}[/tex]

cos(x) = 4 / 5

sec(x) = 1 / ( 4 / 5 ) = ( 5/ 4)

The value of tan(x) will be calculated as:-

tan(x) = sin(x)/cos(x) = ( -3 / 5 ) / (4 / 5 )

tan(x) = (-3/4)

Therefore, the value of sec(x) is (5/4) and tan(x) will be (-3)(4).

Answer:

f ( x ) = - 2x^2 + 3x + 1

Step-by-step explanation:

If f ( x ) extends to → − ∞, as x→ − ∞ , provided f(x) → − ∞, as x → +∞, we can rewrite this representation as such;

− ∞  < x < ∞, while y > − ∞

Now the simplest representation of this parabola is f ( x ) = - x^2, provided it is a down - facing parabola;

If we are considering a down - facing parabola, the degree of this trinomial we should create should be even, the LCM being negative. Knowing that we can consider this equation;

Solution; f ( x ) = - 2x^2 + 3x + 1, where the degree is 2, the LCM ⇒ - 2

Answer:A

Step-by-step explanation:

A box-and-whisker plot. The number line goes from 0 to 25. The whiskers range from 2 to 15, and the box ranges from 3 to 8. A line divides the box at 6. Option A is correct.

What is a box plot?

A straightforward method of expressing statistical data on a plot in which a rectangle is drawn to represent the second and third quartiles, with a vertical line inside to indicate the median value. Horizontal lines on both sides of the rectangle show the lower and upper quartiles.

Here,

The lower quartile (Q1) of the data set is 3, so the bottom of the box must start at 3.
The interquartile range (IQR) is 5, so the upper quartile (Q3) must be
Q1 + IQR = 3 + 5 = 8


The median (also called the first quartile) is halfway between Q1 and Q3, so it must be at (Q1 + Q3) / 2 = (3 + 8) / 2 = 6.

The whiskers extend to the minimum and maximum values within 1.5 * IQR of the box, so they must range from 2 to 15.

Parallelogram efgh has sides of length 20 inches and 14 inches as shown. Its acute angle measures 62 degrees. Find the area of efgh to the nearest square inch

Answers

Answer:

The area of the parallelogram is 247 inches^2 to the nearest square inch

Step-by-step explanation:

This question asks us to calculate the area of a parallelogram given the sides and an acute angle.

Please check attachment for diagrammatic representation of the said parallelogram.

Mathematically, the area of the parallelogram can be calculated using the formula;

A = ab sin θ

where a and b refers to the length of the two sides and θ being the acute angle

Substituting these values, we have

A = 20 * 14 * sin 62

A = 280 sin 62 = 247.23 which is 247 inches^2 to the nearest square inch

Guyss please help me with this question. I tried a thousand times but it's still incorrect.

Answers

Answer: [tex]17.68cm[/tex]

Step-by-step explanation:

Using the area formula of a cone, find the height first.

[tex]A=\pi r(r+\sqrt{h^2+r^2})[/tex]

Solve for h,

Begin by dividing by [tex]\pi r[/tex]

[tex]\frac{A}{\pi r}=r+\sqrt{h^2+r^2}[/tex]

Subtract r.

[tex]\frac{A}{\pi r}-r=\sqrt{h^2+r^2}[/tex]

Square both sides.

[tex](\frac{A}{\pi r}-r)^2=(\sqrt{h^2+r^2})^2[/tex]

[tex](\frac{A}{\pi r}-r)^2=h^2+r^2[/tex]

Subtract [tex]r^2[/tex]

[tex](\frac{A}{\pi r}-r)^2-r^2=h^2[/tex]

Extract the square root.

[tex]\sqrt{(\frac{A}{\pi r}-r)^2-r^2 } =\sqrt{h^2}[/tex]

[tex]\sqrt{(\frac{A}{\pi r}-r)^2-r^2 } =h[/tex]

Plug in your values.

[tex]\sqrt{[\frac{670cm^2}{(3.14)(8cm)}-(8cm)]^2-(8cm)^2 } =h[/tex]

Solve;

[tex]\sqrt{[\frac{670cm^2}{25.12cm}-(8cm)]^2-(8cm)^2 } =h[/tex]

[tex]\sqrt{[26.67cm-(8cm)]^2-(8cm)^2 } =h[/tex]

[tex]\sqrt{(18.67cm)^2-(8cm)^2 } =h[/tex]

[tex]\sqrt{348.57cm^2-64cm^2}=h[/tex]

[tex]\sqrt{284.57cm^2}=h[/tex]

[tex]15.77cm=h[/tex]

------------------------------------------------------------------

Now, to find the slant height use this formula: [tex]l=\sqrt{h^2+r^2}[/tex]

[tex]l=\sqrt{(15.77cm)^2+(8cm)^2}\\l=\sqrt{248.69cm^2+64cm^2}\\ l=\sqrt{312.69cm^2}\\ l=17.68cm[/tex]

A boat is anchored 2.2 km due south of a lighthouse. Along the shore, the town of Beachton is 16.8 km due east of the lighthouse. Enter a number in the box to correctly complete the statement. Round the answer to the nearest tenth. The distance from the boat to Beachton is 16 point 9 km

Answers

Answer:

16.9 km

Step-by-step explanation:

From the diagram attached, we can see that the problem forms a triangle.

So, to find the distance(d) from the boat to Beachton , we can make use of Pythagoreas theorem.

Thus;

d² = 16.8² + 2.2²

d² = 282.24 + 4.84

d² = 287.08

d = √287.08

d = 16.9434

Approximating to the nearest tenth, we have;

d ≈ 16.9 km
