Answer:

<4 = 88

<3 = 92

Step-by-step explanation:

The sum of the angles of a triangle is 180

<4 + 45+ 47 = 180

<4 + 92 = 180

< 4 = 180-92

<4 = 88

We know the <3 and <4 form a line

<3 + <4 = 180

<3 + 88 = 180

< 3 = 180-88

<3 = 92

Answer:

$0.13

Step-by-step explanation:

To find how much tax you would pay, find 4.4% of 3:

3(0.044)

= 0.132

Round to the nearest hundredth:

0.132

= 0.13

So, you would pay $0.13 in tax

Answer:

30kg

Step-by-step explanation:

what we know is that 3a - 20kg is b. and if a + 3a -20kg = 100kg, it becomes algebra .

So, we move it over to the sides:

4a = 120kg

(here i moved -20kg to the 100kg and did the reverse. I also added the a's)

which means a = 120kg divided by 4

a = 30kg

Answer:

a. x = 10

b. x = 3/5

c. x = 16

d. x = 21/32

Step-by-step explanation:

a - 2x/3 + (x+3)/3 = 11

b - 3/x + 6/x = 15

c - x/2 + x/8 = 10

d - 4/x + 5/4x = 8

Answer:

4

Step-by-step explanation:

1. Information

Another word for the average rate of change is the slope. The question is essentially asking, what the slope is over the interval of [3, 4]. Hence, one will use the following points, that are on this given function;

(3, -5), (4, -1)

One must also know that the formula for slope is;

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

2. Solving

Answer:

∠TAC is approximately equal to 61.6°

Step-by-step explanation:

The given parameters for the pyramid are;

The dimension for the rectangular base are; Length = 9 cm, width = 7 cm

The length of the diagonal sides, TA, TB, TC, and TD = 12 cm each

The midpoint of the rectangular base = Point M

The diagonal AC = AM + MC

AM = MC as given M is the midpoint of the rectangular base

∴ AC = AM + MC = 2·AM

By Pythagoras' theorem, AC = √(9² + 7²) = √130

AC = √130 cm

∴ AM = AC/2 = (√130)/2 cm

Alternatively, AM = √((9/2 cm)² + (7/2 cm)²) = √(32.5) cm

∠TAC = ∠TAM

By trigonometric ratios, we have;

[tex]cos (\theta) = \dfrac{Length \ of \ adjacent \ side \ to \ angle }{Length \ of \ hypotenuse\ side \ to \ angle}[/tex]

[tex]\therefore cos (\angle TAM) = cos (\angle TAC) = \dfrac{\left (\dfrac{\sqrt{130} }{2} \right )}{12} = \dfrac{\sqrt{130} }{2 \times 12} = \dfrac{\sqrt{130} }{24}[/tex]

[tex]\angle TAC = arccos \left ( \dfrac{\sqrt{130} }{24} \right ) \approx 61.6 ^{\circ} \ to 1 \ decimal \ place[/tex]

The measure of angle TAC is 61.6 degrees

The given parameters are:

[tex]\mathbf{AB = 7}[/tex]

[tex]\mathbf{BC = 9}[/tex]

Start by calculating length AC, using the following Pythagoras theorem.

[tex]\mathbf{AC = \sqrt{AB^2 + BC^2}}[/tex]

So, we have:

[tex]\mathbf{AC = \sqrt{7^2 + 9^2}}[/tex]

[tex]\mathbf{AC = \sqrt{49 + 81}}[/tex]

[tex]\mathbf{AC = \sqrt{130}}[/tex]

[tex]\mathbf{AC = 11.40}[/tex]

Next, we calculate side length AM

[tex]\mathbf{AM = \frac{AC}{2}}[/tex]

So, we have:

[tex]\mathbf{AM = \frac{11.40}{2}}[/tex]

[tex]\mathbf{AM = 5.70}[/tex]

The measure of angle TAC is calculated using the following cosine ratio

[tex]\mathbf{cos(A)= \frac{AM}{TA}}[/tex]

So, we have:

[tex]\mathbf{cos(A)= \frac{5.70}{12}}[/tex]

[tex]\mathbf{cos(A)= 0.475}[/tex]

Take arc cos of both sides

[tex]\mathbf{A= 61.6}[/tex]

Hence, the measure of angle TAC is 61.6 degrees

Step-by-step explanation:

Answer:

x = −8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(x + x)  + (75 +53 + 68) = 180 (Combine Like Terms)

2x + 196 =180

Step 2: Subtract 196 from both sides.

2x + 196 − 196 = 180 −196

2x = −16

Step 3: Divide both sides by 2

x = -8

Step-by-step explanation:

Remark

The easiest way to do this is to take the two intercepts (x  and   y)

x intercept: (-4,0)

y intercept: (0,2 )

Givens

y2 = 2

y1  = 0

x2 = 0

x1 = - 4

Equation

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

Solution

m = (2 - 0)/(0 - - 4)

m = 2/4 = 1/2

Find b

y = mx + b

y = 2

x = 0

2 = 1/2x +  b

Given that,

Karen will divide her garden into equal parts. She will plant corn in 12/20 of the garden.

To find,

The fewest number of parts she can divide her garden into.

Solution,

It is mentioned that she will plant corn in 12/20 of the garden.

If we divide both numerator and denominator by 4, it will become:

[tex]\dfrac{12/4}{20/4}=\dfrac{3}{5}[/tex]

It means the fewest number she can divide her garden into is 4. 3/5 part is planted with corn and rest 2/5 is not planted with corn plant.

Answer:

-6

Step-by-step explanation:

The first step is to make the fractions have a common denominator. It can be achieved by finding the LCM (Lowest common multiple) of the fractions denominators

From the question,

The given expression is 4/5 + 1/2

This can be written properly as

[tex]\frac{4}{5}+\frac{1}{2}[/tex]

In solving the problem, the first step is to make the fractions have a common denominator. This can be achieved by finding the LCM (Lowest common multiple) of their denominators (that is, 5 and 2)

The LCM of 5 and 2 is 10

If we were to solve the equation, we will get

[tex]\frac{4}{5}+\frac{1}{2}[/tex]  = [tex]\frac{2(4) + 5(1)}{10}[/tex]

Hence, the first step is to make the fractions have a common denominator. It can be achieved by finding the LCM (Lowest common multiple) of the fractions denominators.

Answer:

Rs 42000 and Rs 40000

Step-by-step explanation:

Given that Rs 82000 is divided into two parts.

Let the first part be Rs x which is compounded annually at the interest of 5% per annum for 2 years.

The rate of interest = 5%=0.05

The total amount after 2 years [tex]= x(1+0.05)^{2}\cdots(i)[/tex]

The other part is Rs 82000-x which is compounded annually at the interest of 5% per annum for 3 years.

The total amount after 3 years [tex]= (82000-x)(1+0.05)^{3}\cdots(ii)[/tex]

As both the amounts are equal, so from equation (i) and (ii)

[tex]x(1+0.05)^{2}=(82000-x)(1+0.05)^{3} \\\\x(1.05)^{2}=82000(1.05)^{3} -x(1.05)^{3} \\\\x(1.05^2+1.05^3)=82000\times 1.05^3 \\\\x(2.260125)=94925.25 \\\\x=94925.25/2.260125 \\\\[/tex]

x= 42000

And the other part = 82000-42000 = Rs 40000

Hence, he divides the money as

Rs 42000 at 5% per annum compound interest in 2 years and

Rs 40000 at 5% per annum compound interest in 3 years.

x/7+1=5

-1       -1

x/7=4

x/7*7=4*7 ( do the inverse operation to get rid of 7, which is multiplication)

x=28

Answer:

x=28

Step-by-step explanation:

x÷7+1=5

Firstly,

Group like terms

x÷7=5-1

x÷7=4

Secondly,

So now 7 will cross the equal sign

x=4×7

We have ×7 because when a number number with a division sign crosses an equal sign it becomes multiplication.

x=28
