Answer 1

Answer:

A)12

Step-by-step explanation:

to understand thisyou need to know about:equationPEMDASlet's solve:

according to the question

[tex] \sf \: 2x + 4 + 62 = 90[/tex]

simplify addition:

[tex] \implies \sf 2x + 66 = 90[/tex]

subtract 66 from both sides:

[tex] \sf\implies 2x + 66 - 66 = 90 - 66 \\ \sf\implies2x = 24[/tex]

divide both sides by 2:

[tex] \sf \implies \: \frac{2x}{2} = \frac{24}{2} \\ \sf \therefore \: x = 12[/tex]

Answer 2

Answer:

Solution given:

62°+2x+4+90=180°[ sum of interior angle of a triangle is 180°]

2x=180-156°

x=24°/2

x=12°

A 10-ounce container of chocolate chips can be used to make 4 desserts.
Each dessert has the same number of chocolate chips.

Which equation shows how to find the number of ounces in each dessert?

A number line going from 0 to 10 in increments of 1.


10÷4=104 ounces


4÷10=104 ounces


10÷4=410 ounce


4÷10=410 ounce



Answers

Answer:

So equation will be 4x = 10

A 10 ounce container of chocolate chips can be used to make 4 desserts.

Each desert has the same number of chocolate chips

Let number of chocolate chips in each dessert = x ounce

Therefore, chocolate chips in 4 deserts = 4x and total chocolate chips is = 10 ounce.

So equation will be 4x = 10

Find the value of a and the area of the triangle. Round to the nearest hundredth

Answers

Answer:

a = 6.65

Area = 15.84

Step-by-step explanation:

By cosine rule in the given triangle,

BC² = AC² + AB² - 2(AC)(AB)cos(C)

a² = 5² + 9²- 2(5)(7)cos(28°)

a² = 25 + 81 - 61.81

a = [tex]\sqrt{44.19}[/tex]

a = 6.65

Area of a triangle with given three sides = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Here, s = Average of lengths of all sides

a, b and c are the measures of the respective sides of the triangle.

s = [tex]\frac{6.65+7+5}{2}[/tex]

s = 9.325

a = 6.65, b = 5 and c = 7

Now substitute these values in the formula to get the area,

Area = [tex]\sqrt{9.325(9.325-6.65)(9.325-5)(9.325-7)}[/tex]

        = [tex]\sqrt{9.325\times 2.675\times 4.325\times 2.325}[/tex]

        = [tex]\sqrt{250.8313}[/tex]

        = 15.838

        = 15.84

help lol solve for x

Answers

Answer:

x = 6

Step-by-step explanation:

(8x - 4)° + (3x + 17)° = (17x - 23)° => exterior angle theorem

Solve for x

8x - 4 + 3x + 17 = 17x - 23

Add like terms

11x + 13 = 17x - 23

11x - 17x = -13 - 23

-6x = -36

Divide both sides by -6

x = 6

here, we have,

given that,

Pasta costs £1.50 per kg.

now we have to find,

How much does 600g of pasta cost

we know,

1 kg = 1000 grm.

so, we get,

1000 g Pasta costs £1.50

so, 1 g  Pasta costs £1.50/1000

so, 600 g  Pasta costs £1.50/1000 * 600

                                     = £ 0.9

Hence, The solution is, 600g of pasta cost £ 0.9.

The volume of the rectangular prism is 60 cubic units

What is the Volume of a Rectangle?

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the volume of the rectangular prism be represented as V

Now , the equation will be

The length of the rectangular prism = 3 units

The width of the rectangular prism = 4 units

The height of the rectangular prism = 5 units

Now , the volume is calculated by

Volume of Rectangle = Length x Width x Height

Substituting the values in the equation , we get

Volume of Rectangle V = 3 x 4 x 5

On simplifying the equation , we get

Volume of Rectangle V = 60 cubic units

Therefore , the value of V is 60 cubic units

Hence , the volume of the rectangular prism is 60 cubic units

What value would make the equation 8x = -72 true?

Answers

Answer:x= -9

Step-by-step explanation: You would dive both sides by 8 and -72 divided by 8 is -9

Answer:-9

Step-by-step explanation:

The answer is -9 because we are solving to get x by itself. Since 8 is being multiplied by x the opposite of multiplication is division. Divide both sides by 8 to get x by itself. -72 divided by 8 is -9 because a negative divided or multiplied by a positive is a negative. To check your work you can do 8 times -9 which equals -72.

There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles. How many reptiles are there?

Answers

Answer:

There are 9 000 000 = 9 million reptiles in the US.

Step-by-step explanation:

Percentages and ratio:

The double of a measure, for example, is 200% of the measure.

So 1000% of a measure is 10 times the measure.

There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles.

The number of pet dogs is 10 times the number of reptiles, which means that:

[tex]10x = 90 000 000[/tex]

[tex]x = \frac{90 000 000}{10}[/tex]

[tex]x = 9 000 000[/tex]

There are 9 000 000 = 9 million reptiles in the US.

The required value of altitude y is 9 units which is determined by the geometric theorem.

What is the right triangle?

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

As we know that the geometric theorem states that h = √(ab),

where h is the altitude of a right triangle, a and b are the segments formed when the altitude divides the hypotenuse of a right triangle.

We have to determine the value of altitude y

As per the given figure, a = 3, and b = 27

Substitute the values  in the formula, and we get

y = √(3 × 27)

y = √81

y = 9

Therefore, the measure of y = 9.
