Answer:

First term is 15

Step-by-step explanation:

Given data:

[tex]a_{7} =3\\d=-2[/tex]

Now,

[tex]a+6d=3.....(1)\\a_{n} =a+(n-1)d\\\\\\From equation (1)\\a+6(-2)=3\\a-12=3\\a=12+3\\a=15[/tex]

Therefore first term a =15

Correct option is (c)

Answer:

21 hours

Step-by-step explanation:

We can use a ratio to solve

7 houses       30 houses

-------------  = --------------

5 hours         x hours

Using cross products

7x = 5*30

7x = 150

Divide by 7

7x/7 =150/7

x =21.42857143

Rounding to the nearest whole number

x = 21 hours

Answer:

5 sqrt(2) =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hypotenuse

sin 45 = x / 10

10 sin 45 = x

10 ( sqrt(2)/2) =x

5 sqrt(2) =x

Answer:

x2 + 7x + 12 = 0

Step-by-step explanation:

(x + 4) (x + 3)

x + 4 = 0 or x + 3 = 0

x = - 4 or x = - 3

Answer:

30

Step-by-step explanation:

There are 14 data points on the plot

The median is the middle value, which is between the 7th and 8th data points

Since it is even, we find the average of the 7th and 8th data points

Add the 7th and 8Th data points values and divide by 2

( 30+30)/2 = 60/2 = 30

The median is 30

Answer:

30

Step-by-step explanation:

Middle numbers are 30 and 30 so you add them and then divide by two:

[tex]\frac{30 + 30}{2}[/tex] = [tex]\frac{60}{2}[/tex]= 30

Positive gradient, and the y intercept for the graph is -3, F is not the answer, the Y intercept is not -3.

Answer:

0.1%

Step-by-step explanation:

Given that 240 g of 2.5 kg

We have to express this in percentage

But we know that 1 kg = 1000 g, So first convert 2.5 kg to g

2.5 kg = 2.5 x 1000 g = 2500 g

The formula of "a" % of "b" is given as:

[tex]percentage= \frac{a}{b}[/tex] × 100

Hence, 240 g as a percentage of 2500 g is given as:

[tex]= \frac{250}{2500}[/tex] × [tex]100[/tex]

= [tex]\frac{1}{10}[/tex] = 0.1

Thus, the answer is 0.1 %

Answer:

33.6 meters

Step-by-step explanation:

the wingspan is 1/4 of the original size so all you need to do is multiply the scaled down wingspan by 4

Answer:

Step-by-step explanation:

Let the 2 numbers be x and y

From the problem we have that

x * y = 600 and x + y = 59

From x + y = 59 -> x = 59 - y

Plug x = 59 - y to x * y = 600 we have

(59 - y) * y = 600

-> 59y - y^2 = 600

-> -y^2 + 59y - 600 = 0

-> y = [tex](59 - \sqrt{1081})/2[/tex] or [tex](59 + \sqrt{1081})/2[/tex]

Then we could plug the answers in and find x because x = 59 - y

Answer:

The distributive property is one of the most frequently used properties in math. The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

distributive property is multiplying a number by a sum is the same as doing each multiplication separately.

for example: 2 (4 + 3 )

              2 x 4 = 8

              2 x 3=6

             8+6=14

Answer:

15^18/(15^3)=15^15

Step-by-step explanation:

rule for quotients of similar bases with different exponents is:

(a^c)/(a^b)=a^(c-b)  

15^18/(15^3)=15^15

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

It’s a right angle, so you can add the two expressions togther to get 90, then isolate x.

(8r-6)+(5r+5)=90

13r-1=90 (combine like terms)

13r-1+1=90+1 (add 1, addition property of equality)

13r=91

13r/13=91/13

Answer:

(-8,-8)

Step-by-step explanation:

Coordinates of a midpoint:

The coordinates of the midpoint of a segment is given by the mean of the coordinates of the endpoints.

In this question:

Endpoints (-16,0) and (0,-16).

x-coordinate:

[tex]\frac{-16+0}{2} = -8[/tex]

y-coordinate:

[tex]\frac{0-16}{2} = -8[/tex]

Then:

(-8,-8)

Answer:

T T → T

Step-by-step explanation:

Given :

p = 10 > 7

q = 10 > 5

Evaluating if the statements are true :

p = 10 > 7, This is TRUE, Because 10 is truly greater Than 7

q = 10 > 5, This is TRUE, Because 10 is truly greater Than 5

The statements are both True statements :

p = True ; q = True

True and True = True

T & T = T

T T → T

Answer:

63.69 meters

Answer:

Probably "Median"

The mode doesn't really make sense,

Answer:

a = 153.5 yd²

Step-by-step explanation:

horizontally divide the figure into a tringle and a trapezoid

triangle

a = (1/2)bh

a = (1/2)(19)(7)

a  = 66.5

trapezoid

a = (b₁ + b₂)/2 * h

a = (19 + 10)/2 * (13 - 7)

a = 87

Combined

a = 66.5 + 87

a = 153.5

Answer: A, which is y = 1/2

Step-by-step explanation: To find the value of y, you would need to divide both of the sides by 8. This makes it so that 8y turns into just y. After you do this, you would find an answer of y = 1/2. Hope this was helpful! :)

Answer:

y = 1/2

Step-by-step explanation:

8y = 4

Divide each side by 8

8y/8 = 4/8

y = 1/2

Step-by-step explanation:

4*1 = 4

this indicates multiplication

8/9 = 0.88888888888 which when simplified would go back to 8/9 or .889

8 "over" 9 indicates division!
