Answer:

x = 2\sqrt{13}

Step-by-step explanation:

Using Pythagoras' identity on each of the 3 right triangles

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Outer right triangle

x² + z² = (9 + 4)² = 13² = 169, that is

x² + z² = 169 → (1)

Left right triangle

y² + 4² = x²

y² + 16 = x² ⇒ y² = x² - 16 → (2)

Right right triangle

z² = y² + 9²

z² = y² + 81 → (3)

Substitute (3) into (1)

x² + y² + 81 = 169 ← substitute (2) into here

x² + x² - 16  + 81 = 169

2x² + 65 = 169 ( subtract 65 from both sides )

2x² = 104 ( divide both sides by 2 )

x² = 52 ( take the square root of both sides )

x = \sqrt{52}

  = \sqrt{4(13)}

  = \sqrt{4} × \sqrt{13} = 2\sqrt{13}

Macy was asked to compare the two ratios 4:5 and 19 to 30.
lora16 [44]
The correct answer is C, 4:5 would be equivalent to 24/30, because 30 divided by 5 is equal to 6, so you would multiply the numerator and denominator by the same number.

Chelsea uses 3 pounds of apples to make 4 cups. How many pounds of apple does she need to make 6 pints of applesauce
Gemiola [76]

Here, we know that 1 pint = 2 cups

Thus, 1 cup = \frac{1 pints}{2}

3 ponds apples are needed for 4 cups i.e. 3 ponds of apples = 4 cups of applesauce

1 cup of applesauce = \frac{3 ponds}{4}

Now, 6 pints will have 12 cups of applesauce

Multiplying this equation by 12 ⇒ 1 cup of applesauce = \frac{3 ponds}{4}

12 ×1 cup of applesauce = 12 × \frac{3 ponds}{4}

So, 12 cups of applesauce = 9 ponds of apple.

<u>Thus, 9 ponds of apple will be needed to make 6 pints of applesauce.</u>

Based on the data table, which equation accurately represents the situation?
8090 [49]

Answer:

The equation of the line is:

y = 28x

Hence, option C is correct.

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the table

Gallons               Miles Driven

8                          224

10                         280

4                           112

Finding the slope between any two points, let say (8, 224) and (10, 280)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(8,\:224\right),\:\left(x_2,\:y_2\right)=\left(10,\:280\right)

m=\frac{280-224}{10-8}

m=28

now substituting (8, 224) and m = 28 in the slope-intercept form of line equation

y = mx+b

224 = 28(8) + b

224 = 224 + b

b = 0

Thus, the y-intercept b = 0

now substituting b = 0 and m = 28  in the slope-intercept form of line equation

y = mx+b

y = 28x+0

y = 28x

Therefore, the equation of the line is:

y = 28x

Hence, option C is correct.

1. Which are true of x = log10 31,500? Select all that apply.
ziro4ka [17]

Given:

x=\log_{10}31,500

To find:

Select the true statements from the given options about the given value.

Solution:

We have,

x=\log_{10}31,500

It can be written as

x=\log_{10}(2^23^25^37)

x=\log_{10}(2^2)+\log_{10}(3^2)+\log_{10}(5^3)+\log_{10}(7)     [\because \log(ab)=\log a+\log b]

x=2\log_{10}2+2\log_{10}3+3\log_{10}5+\log_{10}(7)

x=2\left(0.30105\right)+2\left(0.47712\right)+3\left(0.69897\right)+0.8451

x=4.49835

Clearly, the value of x lies between 4 and 5. So, x>4 and x.

Therefore, the correct options are C and D.
