Bianca has to drive 180 miles to her aunt’s house. She drove 30% of the total distance before lunch. How many miles did Bianca drive before lunch? Show your work.

Answer:

51°

Step-by-step explanation:

Given

<QPR = 39°

<PQR = 90° ( inscribed angle in semi circle)

Now

<QPR + <PQR + <PRQ = 180° { being sum of angles of triangle)

39° + 90° + <PRQ = 180°

<PRQ = 180° - 39° - 90°

<PRQ = 51°

Step-by-step explanation:

set the denominator to equal 0

(x-7)(x+5) = 0

x = 7, x = -5

all real numbers except -5 and 7

Step-by-step explanation:

it would be like 500.5% or 1001/200

Answer:

Two places to the right.

Step-by-step explanation:

Since theres  two zeros in 100, move the decimal two places to the right, making it 400.3.

Answer:

600

Step-by-step explanation:

set x as the number

x0.10 = 60

x = 60/0.10

x = 600

Answer:

For me i think its 16.67 well im not fully sure

Step-by-step explanation:

SO we have to figure out what gives us 10 and that will be represented as "x"

[tex]\frac{60}{100}[/tex]  × x = 10

Multiplying both sides by 100 and dividing both sides by 60,

we have x = 10 × [tex]\frac{100}{60}[/tex]  so, x = 16.67

(that's what i believe but i don't know)

Answer:A

Step-by-step explanation:

Interior angles of a triangle ALWAYS have to be equal to 180

The sum of A is 180, however, those angles wont work because they have to be more close to eachother for it to be possible

The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides

Answer:

its 3/2

Step-by-step explanation:

Answer:

none x= 3/2

Step-by-step explanation:

Answer:

1/2 ; 0 ; 2 ;

Step-by-step explanation:

3 / 8 to the nearest half

3/8 = 0.375

Using a number line, 0.375 is closer to 1/2 =0.5, than to 0 ; hence, 3/8 = 1/2(nearest half

2.) 2 /12 = 0.16666

2/12 = 0 (nearest 1/2)

3.) eight tenths plus nine tenths equals

8/ 10 + 9/10 = 17/10

17 /10 = 1.7

1.7 = 2 (nearest 1/2)

Answer:

5r - 40

Step-by-step explanation:

If you simplify 5(r - 8), you will get 5r - 40. This is called distributed property.

Answer:

19 feet

Step-by-step explanation:

The perimeter is calculated by multiplying the sum of length and width by 2

width is 3 less than length so if we call the width x the length would be x + 3

2×(x + x + 3) = 4x + 6 and

4x + 6 = 70 subtract 6 from both sides

4x = 64 divide both sides by 4

x = 16

The length is x + 3 so the answer is 19 feet

Answer:

11.6

Step-by-step explanation:

The length of f of the triangle is f = 11.7 cm

The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:

c² = a² + b² - 2ab cos(C)

where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.

Given data ,

Let the triangle be represented as ΔEFG

And , the measures of the sides of the triangle are

g = 4.3 cm

e = 9.1 cm

And , measure of angle ∠F = 116°

where c² = a² + b² - 2ab cos(C)

On simplifying , we get

a² = c² - b² + 2abcos ( C )

78.26 ( cos 116° ) - 4.3² - 9.1² = f²

f² = 135.7344

Taking square roots on both sides , we get

f = 11.7 cm

Hence , the length is f = 11.7 cm

  (b)  7720 mm² of paper

Step-by-step explanation:

The central horizontal rectangle of the net is 80 mm high and ...

  40 + 5.5 + 40 + 5.5 = 91

mm long. Its area 9 is ...

  (80 mm)(91 mm) = 7280 mm²

__

The two pieces of the net not accounted for above are the "flaps" above and below the central rectangle. Each of those two has an area of 40 mm by 5.5 mm, so their total area is ...

  2(40 mm)(5.5 mm) = 440 mm²

Then the area of paper needed for the wrapper is ...

  total area = 7280 mm² + 440 mm²

  total area = 7720 mm²

Answer:

[tex]Sum = (15x - 44)^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle y = (2x - 3)^{\circ}[/tex]

[tex]\angle z = (13x - 41)^{\circ}[/tex]

Required

Calculate the sum of the two angles

[tex]Sum = \angle y + \angle z[/tex]

[tex]Sum = (2x - 3)^{\circ} + (13x - 41)^{\circ}[/tex]

Collect Like Terms

[tex]Sum = (2x +13x)^{\circ} - (3+ 41)^{\circ}[/tex]

[tex]Sum = (15x)^{\circ} - (44)^{\circ}[/tex]

[tex]Sum = (15x - 44)^{\circ}[/tex]

Hence, the sum of the two angles is 15x - 44

Answer:

The answer to the question is -1.32

Step-by-step explanation:

The first step will be to write out the equation that we are working with:

This equation is

[tex]0.2b + 0.6a = 12[/tex]

The next step is to write out the values of the figures that we are substituting:

[tex]a = -1.2 b=-3[/tex]

Substitution in mathematics can best be understood as "something being used in place of another thing". This means that wherever the first variable appears in an equation, the substituting values will replace it and multiply the number it is attached to.

In this case, we will replace the 'b' and the 'a' with the - 1.2 and - 3 respectively.

[tex]0.2(-3) + 0.6(-1.2) = -1.32[/tex]

Answer:

440h is the expression. When 3 1/4 is evaluated you get 1,430 calories burned.

Step-by-step explanation:

440 represents the number of calories she burns per hour. To represent the hour, we place a variable which is h. After we write the expression, we substitute 3 1/4 for h. When I did this, I turned 3 1/4 into an improper fraction, which was 13/4, and then divided 13 by 4 to get 3.25

Multiple 3.25 by 440 to get an answer of 1,430 calories burned.
