Answer:

40

48

56

64

72

80

Step-by-step explanation:

From 1-10 You can see the numbers going from 0-8 on the left side except you repeat the number 4 twice then proceed. Then on the right side you do it backwards but instead you use the 2 times tables and you’re going to want to work your way from bottom to top and then when you reach to 0 which is the number 10 you repeat the 2 times tables again.

Given:

An angle θ on the unit circle has a sine of [tex]\dfrac{1}{4}[/tex].

To find:

The value of cosθ.

Solution:

We have,

[tex]\sin \theta=\dfrac{1}{4}[/tex]

Since sinθ is positive, therefore, θ lies in first or second quadrant.

We know that,

[tex]\sin^2 \theta +\cos^2 \theta =1[/tex]

[tex](\dfrac{1}{4})^2+\cos^2 \theta =1[/tex]

[tex]\dfrac{1}{16}+\cos^2 \theta =1[/tex]

[tex]\cos^2 \theta =1-\dfrac{1}{16}[/tex]

Taking square root on both sides.

[tex]\cos \theta =\pm \sqrt{\dfrac{16-1}{16}}[/tex]

[tex]\cos \theta =\pm \dfrac{\sqrt{15}}{4}[/tex]

Therefore, the value of cosθ is either [tex]\dfrac{\sqrt{15}}{4}[/tex] or [tex]-\dfrac{\sqrt{15}}{4}[/tex].

Answer:

4y + 7

Step-by-step explanation:

Simplify. Use the distribution method, and follow PEMDAS.

PEMDAS is the order of operation. It stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

Distribute 4 to all terms within the parenthesis. In this case, you are multiplying 4 to all the terms:

4(y + 3) = (4 * y) + (4 * 3) = 4y + 12

Next, combine like terms (terms with the same amount of variables);

4y + 12 - 5

4y + (12 - 5)

4y + 7

4y + 7 is your simplified expression.

Answer:

Mean:(137.2)

Median:(139.5)

Step-by-step explanation:

Mean = (125+136+150+119+143) divide by six(6)

= 823/6 = approx 137.2

Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.

119,125,136,143,150, 150. so 136 & 143 is the middle number.

so you will add the middle number and divide by 2.

that is 136+143/2 = 139.5.

Answer:

113.04

Step-by-step explanation:

formula for area is

pi times radius times radius

if the radius is 6,

do 6 times 6=36

36 times 3.14=113.04

Answer:

D: 15

Step-by-step explanation:

Ok, by looking at the first equation, you know that one triangle equals 10. By looking at the second one, you see that two circles equal 10, since 20- triangle(10) equals 10. This means a circle has to equal 5. looking at the third one, the answer is 13, and a circle is 5, so 13-5=8. Two squares equal 8. the last one shows one triangle, one circle, and a half square. From the third one, you know that one square equals 4, so a half square equals two. I do not know why this logic doesn't match with the answers, since 10(triangle) plus 5(circle) and 2(half square) is 17, but in terms of what makes sense and just matching it with the answers provided, I say go with the third option.

Answer:

$56,097

Step-by-step explanation:

First, we have to figure out how much his raise was, so we can convert 3.5% directly to a decimal:

3.5% = 0.035

Then we find

3.5% of 54,200 = 0.035 x 54,200 = 1,897

1,897 + 54,200 = 56,097

So, Mills new salary is $56,097

hope this helps:)

Answer:

Yes, Simon is correct.

Step-by-step explanation:

A trapezoid refers to a quadrilateral that is convex in shape; as such it has no equal sides and no parallel sides.

Let the height of a trapezoid be h.

Let the top base of a trapezoid be b1.

Let the bottom base of a trapezoid be b2.

[tex] Area \; of \; trapezoid = \frac {1}{2} * (Sum \; of \; nonparallel \; sides) * height [/tex]

Therefore, [tex] Area \; of \; trapezoid = \frac {1}{2} * (b_{1} + b_{2}) * h [/tex]

[tex] Area \; of \; trapezoid = \frac {1}{2} * (b_{1}h + b_{2}h) [/tex]

[tex] Area \; of \; trapezoid = \frac {b_{1}h + b_{2}h}{2} [/tex]

Hence, to find the area of a trapezoid, you will multiply the height by the top base and the height by the bottom base. Then you add the two products together and divide the sum by 2.

well u can transfer the -5 in denominator to the right hand side

so x=1.2*(-5)

x=-6.0
