masya89 [10]

Answer:

The measurement found using Ruler 2 is more accurate and more precise.

Step-by-step explanation:

Ruler 1 has fewer tick marks, Ruler 2 has more which indicates a more precise, exact, accurate reading.

Katie has read 34% of a book. If she read 85 pages, does she have more than or fewer than 125 pages left to read? Explain

mestny [16]

Determine the percent of book she hasn't read.
percent = 100% - percent she has read
percent = 100% - 34%
percent = 66%
She hasn't read 66% of the book.

Find the amount of page she hasn't read.
page = $\dfrac{\text{percent hasn't read}}{\text{percent has read}} \times\ \text{page has read}$
page = $\dfrac{66\%}{34\%} \times\ 85$
page = $\dfrac{66}{34} \times\ 85$
page = $\dfrac{5,610}{85}$
page = 165

The number of page she hasn't read is 165. It's more than 125.

Need help with this math problem

-BARSIC- [3]

z = 37°

Step-by-step explanation:

The exterior angle theorem says that the sum of two internal angles is equal to the exterior angle

In this case the sum of z and z+4 will be equal to z+41

Writing mathematically

$z + z+ 4 = z + 41\\2z+4 = z + 41\\2z -z = 41 -4\\z = 37$

Hence

z = 37°

While at camp Mrs Ktenas asked 24 of her year 12 students to plant apple and

soldi70 [24.7K]

Answer:

6 apple trees, 18 orange trees

Step-by-step explanation:

Let the number of boys be x and the number of girls be y

x+y=24

As each three boys plant 1 tree, each boy plants 1/3 trees

Each girl plants 3 trees

Note that the type of tree is irrelevent at this point as we are working out the number of boys and girls by the total number of trees

x/3+3y=24

x+y=24

Times x/3+3y=24 by 3

x+9y=72

x+y=24

Minus the first equation with the second equation, we get that

8y=48

y=6

substitute into the equation

x+6=24

x=18

As each 3 boys plant a apple tree, total apple trees planted by boys=18/3=6

As each girl plants 3 orange trees, total orange trees planted by girls=6*3=18

Let (-7, 2) be a point on the terminal side of 0.

nekit [7.7K]

By applying the definitions of trigonometric functions, the exact values of the sine, secant and tangent of the point on the terminal side are $\sin \theta = \frac{2}{\sqrt{53}}$ , $\sec \theta = -\frac{\sqrt{53}}{7}$ and $\tan \theta = -\frac{2}{7}$ .

<h3>How to determine the exact values</h3>

In this question we need to find the exact values of three trigonometric functions associated with the terminal side of an angle. The following definitions are used:

Sine

$\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}$ (1)

Secant

$\sec \theta = \frac{\sqrt{x^{2}+y^{2}}}{x}$ (2)

Tangent

$\tan \theta = \frac{y}{x}$ (3)

If we know that x = - 7 and y = 2, then the exact values of the three trigonometric functions:

Sine

$\sin \theta = \frac{2}{\sqrt{53}}$

Secant

$\sec \theta = -\frac{\sqrt{53}}{7}$

Tangent

$\tan \theta = -\frac{2}{7}$

By applying the definitions of trigonometric functions, the exact values of the sine, secant and tangent of the point on the terminal side are $\sin \theta = \frac{2}{\sqrt{53}}$ , $\sec \theta = -\frac{\sqrt{53}}{7}$ and $\tan \theta = -\frac{2}{7}$ .

<h3>Remark</h3>

The statement reports typing errors, correct form is shown below:

Let (x, y) = (- 7, 2) be a point on the terminal side of θ. Find the exact value of sin θ, sec θ and tan θ.
