Answer 1

Answer: x = 62.5 degrees

Step-by-step explanation:

Angle DEC is adjacent to the angle measuring 137 degrees, which means their sum is 180 degrees. Therefore:

Angle DEC + 137 = 180

We can subtract 137 from both sides:

Angle DEC = 43 degrees

We know that the sum of the angles in a triangle is 180 degrees, so we can set up an equation for triangle DEC.

We know Angle D + Angle C + Angle E = 180, so we can plug in the values given for each.

Therefore, x + 5 + x + 7 + 43 = 180

We can combine like terms:

2x + 55 = 180

Subtract 55 from both sides:

2x = 125

Divide both sides by 2:

x = 62.5 degrees

The previous triangular prism had a surface area of 288 square units. What happens to the surface area of your prism when you double all four measurements? the surface area doubles. The surface area triples. The surface area increases by 4 times. The surface area increases by 8 times.

Answers

Answer:

The surface area increases by 4 times.

Step-by-step explanation:

square root of 288 = 16.970562.... (= 1 side)

1 side(x2) = 33.941125...... (= double of the side)

New area = new side squared

(33.94111....) squared =  1,152 (new area)

1,152/288 = 4    

new area is 4 times bigger

288 x4 = 1,152

jessica used 2/3 of her money to but books and 1/6 of her money to buy notebooks. she then had 30$ left in her pocket.How much money did Jessica have i her pocket before shopping?

Answers

Answer:

2/3x + 1/6x = 30

x represents her money, because it is unknown

and 30 represents the leftover money she was left, so we solve for x.

x - (2/3x + 1/6x) = 30

Combine multiplied terms into a single fraction.

Find a common denominator;

x - 4/6x - 1/6x = 30

Combine fractions with common denominator.

Multiply all terms by the same value to eliminate fraction denominators;

6x - 4x - 1x / 6 = 30

Cancel multiplied terms that are in the denominator.

x/6 = 30

Multiply them.

*6     *6

To get,

x = 180

Jessica had 180 dollars in her pocket before shopping.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let's assume that Jessica had 'x' dollars in her pocket before going shopping.

Jessica used 2/3 of her money to buy books, which is (2/3)x dollars.

She used 1/6 of her money to buy notebooks, which is (1/6)x dollars.

So, the total amount of money spent on books and notebooks is:

(2/3)x + (1/6)x = (4/6)x + (1/6)x = (5/6)x

Jessica had 30 dollars left in her pocket after shopping. So, we can write:

x - (5/6)x = 30

Simplifying the equation, we get:

(1/6)x = 30

Multiplying both sides by 6, we get:

x = 180

Therefore, Jessica had 180 dollars in her pocket before shopping.

What happens when the slope decreases? Write 4 sentence's

Answers

Answer:

Suppose the slope of a line were to decrease. Then it would get flatter. These conditions are true whether or not the slope was positive or negative to begin with. A higher positive slope means a steeper upward tilt to the line, while a smaller positive slope means a flatter upward tilt to the line.

For a decreasing function, the slope is negative. The output values decrease as the input values increase. A line with a negative slope slants downward from left to right as in (b). If the function is constant, the output values are the same for all input values so the slope is zero.

Dylan needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 5.5 hours and charged him $71 for parts. The total was $648.50. What was the cost of labor, per hour?

Answers

Answer:

$105 per hour

Step-by-step explanation:

$648.50 - $71 = $577.50

$577.50 / 5.5 = $105 per hour

105 x 5.5 = 575.50

+ 71.00

648.50

The per hour charge of the technician is given as $15.

What is the application ratio and proportion?

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

The given problem can be solved by ratio method as follows,

The remaining cost charged by the technician is $648.50 - $71 = $577.50

Now, the per hour charge is remaining cost divided by total number of hours as given below,

577.50/5.5

= 57750/550

= 15

Hence, the cost of labor per hour is given as $15.

A triangle has a base of 8 feet and a height of 6 feet. By how much does the height need to increase for the area to increase by 2 square feet? Write your answer as a decimal. plss help me

Answers

Answer:

0.5 ft

Step-by-step explanation:

Base = 8 ft and Height = 6 ft

Area of Triangle = 0.5*b*h

Area of Triangle = 0.5*8*6 = 24 sq.ft

To increase the Area by 2 sq.ft  so the New Area will be 26 sq.ft

New Area = 0.5*b*(New Height)

26=0.5*8*(New Height)

New Height = 6.5 ft

The Increase in Height = New Height - Old Height =  6.5 - 6 = 0.5 ft

The increase in the height of the triangle which has a base of 8 feet and a height of 6 feet, to increase its area by 2 square feet is 0.5 feet.

How do we determine the area of a triangle?

The area of a triangle is half the product of its base and its height, that is,

Area = (1/2)*base*height.

How do we solve the given question?

We have been asked to find the increase in the height of a triangle with base(b) = 8 feet and height(h) = 6 feet, such that its area increases by 2 square feet.

First, we find the initial area of the triangle,

Area = (1/2)*b*h (1/2)*8*6 = 24 square feet.

New area = initial area + 2 square feet = 24 + 2 = 26 square feet

Let the increase in height be x feet,

∴ New height(h1) = 6+x feet

∴ New area = (1/2)*8*(6+x),

But we know that the new area is 26 square feet, so we equate them to get:

(1/2)*8*(6+x) = 26

or, 4(6+x) = 26

or, 24 + 4x = 26

or, 4x = 26 - 24 = 2

or, x = 2/4 = 0.5

∴ The increase in the height of the triangle which has a base of 8 feet and a height of 6 feet, to increase its area by 2 square feet is 0.5 feet.

Based on the amount of wheat exported by Canada and Mexico, the number of times more wheat exported by Canada over Mexico is 0.26 times.

By how much more than Mexico, does Canada export wheat?

This can be found by the formula:

= Amount of wheat exported by Canada / Amount of wheat exported by Mexico

The circumference of a circular rug is 24.8 meters. What is the area of the rug? Use 3.14 for π and round your answer to the nearest tenth.

Answers

Answer:  49.0 square meters

====================================================

Explanation:

We'll first need to find the radius of the rug using the circumference.

C = 2*pi*r

r = C/(2pi)

r = (24.8)/(2*3.14)

r = 3.949045 which is approximate.

Now we can find the area

A = pi*r^2

A = 3.14*(3.949045)^2

A = 48.968163 this is also approximate

Rounding to the nearest tenth gets to 49.0
