Can you solve this triangle:
m∠B=47°
a=24
b=22
Please show work, too. Thanks

Answer:

w < -2/45

Step-by-step explanation:

To solve the inequality, solve for w.

Divide each side by 10:

-4/9 > 10w

-2/45 > w

So, the solution to the inequality is w < -2/45

Answer:

w<-2/45

w∈(-∞,-2/45)

Step-by-step explanation:

10w<-4/9  /10

w<-2/45

w∈(-∞,-2/45)

Answer:

Equation : y=3x

Interpret the slope : 3

Interpret the y-Intercept : 0

Answer:

∠BAC = 105°

Step-by-step explanation:

2(5x) = 9x+21

10x = 9x+21

reduce:

x = 21

∠BAC = 5x = 105°

Answer:

28

Step-by-step explanation:

Mean is just another word for "the average."

To get the mean, you first need to add up al of your values together.

30+15+30+20+45=140

You then divide your product by the number of original values. In this case, there are 5 values.

140/5=28

Answer:

you have $180, total there is $1280

Step-by-step explanation:

The required amount we have is given as $410, as of the given condition.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,
Let the amount we and Dotun has to be x and y,
According to the question,
x  = y - 460- - -- - -(1)

x + y = 1280 - - - (2)
From equation 1
y - 460 + y = 1280
2y = 1280 + 460
y = 1740/2
y = $870

Now,
x = 870 - 460
x = $410

Thus, the required amount we have is given as $410, as of the given condition.

Answer:

-5

Step-by-step explanation:

the answer is -5 because it's a loss, meaning he now has -5 dollars from what he had before.

Hope this helps!!

Answer:

x = 5

Step-by-step explanation:

(10/3)/5 = (x+1)/9

(10/3)9 = 5(x+1)

90/3 = 5x + 5

30 = 5x + 5

25 = 5x

x = 5

Opening Exercise

The original triangle, labeled A, has been reflected across the first line, resulting in the image labeled B. Reflect the image across the second line. Carlos looked at the image of the reflection across the second line and said, “That’s not the image of triangle A after two reflections; that’s the image of triangle A after a rotation!” Do you agree? Why or why not?

Discussion

When you reflect a figure across a line, the original figure and its image share a line of symmetry, which we have called the line of reflection. When you reflect a figure across a line and then reflect the image across a line that intersects the first line, your final image is a rotation of the original figure. The center of rotation is the point at which the two lines of reflection intersect. The angle of rotation is determined by connecting the center of rotation to a pair of corresponding vertices on the original figure and the final image. The figure above is a 210° rotation (or 150° clockwise rotation).

Exploratory Challenge

Line of symmetry of a figure: This is an isosceles triangle. By definition, an isosceles triangle has at least two congruent sides. A line of symmetry of the triangle can be drawn from the top vertex to the midpoint of the base, decomposing the original triangle into two congruent right triangles. This line of symmetry can be thought of as a reflection across itself that takes the isosceles triangle to itself. Every point of the triangle on one side of the line of symmetry has a corresponding point on the triangle on the other side of the line of symmetry, given by reflecting the point across the line. In particular, the line of symmetry is equidistant from all corresponding pairs of points. Another way of thinking about line symmetry is that a figure has line symmetry if there exists a line (or lines) such that the image of the figure when reflected over the line is itself.

Does every figure have a line of symmetry?

Answer:

(6x + 3) + (7x - 44) = 180

6x + 3 + 7x - 44 = 180

13x - 41 = 180

13x = 221

Answer: 31.416

Step-by-step explanation:

Answer:

Area= 78.5 cm² (3 s.f.)

Circumference= 31.4 cm (3 s.f.)

Step-by-step explanation:

[tex]\boxed{area \: of \: circle = \pi {r}^{2} }[/tex]

In this question, the radius is 5cm thus r= 5.

Area of circle

= π(5²)

= 25π

= 78.5 cm² (3 s.f.)

[tex]\boxed{circumference \: of \: circle = 2\pi r}[/tex]

Circumference of the circle

= 2(π)(5)

= 10π

= 31.4 cm (3 s.f.)

Answer:

[tex]Ratio =16 : 31[/tex]

Step-by-step explanation:

Let

x = Freddie's age and y = His mother's age

Given

2001:=  [tex]x : y = 1 : 11[/tex]

2018:= [tex]x +17: y + 17= 2 : 5[/tex]

Required

The ratio of their age in 2030

[tex]x : y = 1 : 11[/tex]

[tex]x +17: y + 17= 2 : 5[/tex]

Express as fractions

[tex]\frac{x}{y} = \frac{1}{11}[/tex] --- (1)

[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex] -- (2)

In (1), make y the subject

[tex]\frac{x}{y} = \frac{1}{11}[/tex]

[tex]y = 11x[/tex]

Substitute [tex]y = 11x[/tex] in (2)

[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex]

[tex]\frac{x+17}{11x+17} = \frac{2}{5}[/tex]

Cross Multiply

[tex]5(x +17) = 2(11x + 17)[/tex]

[tex]5x +85 = 22x + 34[/tex]

Collect like terms

[tex]22x - 5x = 85 - 34[/tex]

[tex]17x = 51[/tex]

[tex]x =3[/tex]

[tex]y = 11x[/tex]

[tex]y = 11*3[/tex]

[tex]y = 33[/tex]

This means that: In 2001, Freddie was 3 and his mother was 33

In 2030 (29 years after);

Freddie will be: 3 + 29 = 32

His mother will be: 33 + 29 = 62

So, the ratio is:

[tex]Ratio =32 : 62[/tex]

Divide by 2

[tex]Ratio =16 : 31[/tex]

Answer:

16 cm²

Step-by-step explanation:

The dimension of rectangle = 7cm by 4 cm

The Area of the greatest square that can be cut from the rectangle :

The dimension has to be the Same to form a square :

Hence, the greatest width = 4cm

Therefore, taking the length also as 4cm

Area of square = side length²

Greatest area of square that can be cut = 4² = 16cm²

Answer:

4) 8

Step-by-step explanation:

In the formula y = mx + b, m is the slope and b is the y-intercept

m = 8

b = -1

If m = 8 and m is the slope, then the slope is 8

Answer:

It has a negative slope, so B and C are eliminated. The graph also has a solid line instead of a dashed line. This means D is eliminated because it is only greater than. If the graph had a dashed line, then D would be correct, but it does not. So then the answer is A

Answer:

Given

f(x)=18,000(.88)^x

We need to find the value of x when f(x) <2000

0.88^x 1/9

• x = log (1/9) / log (0.88)

• x= 17 (rounded down)
