Answer:

Measure of angle B is 70°.

Step-by-step explanation:

From the given right triangle ABC,

Sin B = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

         = [tex]\frac{AC}{AB}[/tex]

         = [tex]\frac{4.8}{5.1}[/tex]

     B = [tex]\text{Sin}^{-1}(\frac{48}{51} )[/tex]

         = [tex]\text{Sin}^{-1}(0.94118 )[/tex]

         = 70.25

m∠B ≈ 70° [Nearest degree]

Therefor, measure of angle B is 70°.  

Answer:

-22

Step-by-step explanation:

We need to multiply the following:

[tex](\sqrt{10} +2\sqrt{8})(\sqrt{10}-2\sqrt{8})[/tex]

First, we need to FOIL out this expression, then we can simplify it

[tex](\sqrt{10} +2\sqrt{8})(\sqrt{10}-2\sqrt{8})\\\\(\sqrt{10})( \sqrt{10} )+(2\sqrt{8})(\sqrt{10})-(2\sqrt{8})( \sqrt{10})-(2\sqrt{8})(2\sqrt{8}) \\\\10+2\sqrt{80} -2\sqrt{80} -4\sqrt{64} \\\\10-4(8)\\\\10-32\\\\-22[/tex]

The simplified expression after you multiply (square root 10 + 2 square root 8)( square root 10 - 2 square root 8) is -6.

To solve the given expression that needs you to multiply, let's first simplify the individual terms:

Square root of 10: √10

Square root of 8: √8 = √(4 x 2) = 2√2

Now, let's substitute these values into the expression:

(√10 + 2√8)(√10 - 2√8)

Using the distributive property, we can expand this expression as follows:

= (√10 x √10) - (√10 x 2√8) + (2√8 x √10) - (2√8 x 2√8)

= 10 - 2√80 + 2√80 - 4 x 8

= 10 - 16

= -6

Therefore, the simplified expression in square root is -6.

Step-by-step explanation:

Number of more people living in California than in Maine =

[tex]3.9 \times {10}^{ 7} - 1.3 \times {10}^{6} \\ = 39 \times {10}^{ 6} - 1.3 \times {10}^{6} \\ = 37.7 \times {10}^{6} \\ = 3.77 \times {10}^{7} [/tex]

Answer:

A) 27.7

B) 45

Step-by-step explanation:

A) 6 + 9 + 6 + __ = 6.7

To find the other end of the triangle, you would use a² + b² = c².

As shown, one end of the triangle is 6. To find the next end of the triangle, subtract 9 - 6 = 3. So now solve 6² + 3² = c². 36 + 9 = 45. √45 = 6.7. Therefore, the perimeter of the shape is 6 + 9 + 6 + 6.7 = 27.7.

B) Area of the square + area of the triangle = total shape area

6 x 6 = 36 (The area of the square portion of the shape)

6 x 3 = 18 ÷ 2 = 9 (The area of the triangle is half of the area of a rectangle)

36 + 9 = 45

Answer:

x = 4 OR x = -4

Step-by-step explanation:

To find the solution, you can set both equations equal to one another:

(1) y=2x+1; (2) y=x^2+2x-15

2x+1 = x^2+2x-15

Then solve for the x-values that make this true.

2x+1 = x^2+2x-15

1 = x^2 - 15

16 = x^2

x = 4 OR x = -4

Answer:

C. A translation and a dilation

Step-by-step explanation:

Of course it has to be a dilation as the size is obviously different. So that takes D out of the question. The angles are in the same spots as B is still at the highest on both triangles and so does A. Which means it just translated (moved/slide) to the right and up a bit.

Answer: She used half of a pound of flour.

Step-by-step explanation:

The amount of flour she bought to bake some cookies = [tex]\dfrac{3}{4}\text{ of a pound}[/tex]

Since, she used [tex]\dfrac{2}{3}[/tex] of the amount to bake her delicious chocolate chip cookies that means , the amount of flour she used would be

[tex]\dfrac{2}{3}\times\text{amount of flour she bought}\\\\=\dfrac{2}{3}\times\dfrac{3}{4}\text{ of a pound}\\\\=\dfrac{1}{2}\text{ of a pound.}[/tex]

Hence, she used half of a pound of flour.
