Answer:

each apple is £ 1.80

Step-by-step explanation:

i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.

Then i took the remaining money and divided it by 2 to get how much each apple costs.

Answer:

1.80

Step-by-step explanation:

1) Price of Pears

[tex]1.30 * 7 = 9.10[/tex]          formating: 1.30*7 = 9.10

2) Price of Apples

[tex]12.70 - 9.10 = 3.60[/tex]          formating: 12.70-9.10 = 3.60

3) Price of Apples/Kg

[tex]\frac{3.60}{2} = 1.80[/tex]          formating: 3.60/2 = 1.80

Answer:

x = 10    y = 5

Step-by-step explanation:

-4x + 11y = 15

-4(2y) + 11y = 15

-8y + 11y = 15

3y = 15

y = 5

x = 2y

x = 2(5)

= 10

Answer:

length of dotted diagonal line = 11

Step-by-step explanation:

Using the Pythagorean theorem:

length of rectangle² = 9² + 6² = 81 + 36 = 117

length of rectangle = √117 = 10.82

length of diagonal² = 2² + 10.82² = 4 + 117 = 121

length of diagonal = 11

Answer:

  A.  10 units

Step-by-step explanation:

The y-intercept of f(x) is f(0) = -9.

The y-intercept of g(x) is g(0) = g(1)/2 = 1.

The distance between these points is ...

  1 -(-9) = 10 . . . units

__

We notice that the common ratio of the table values of g(x) is 4/2=2, so the value for x=0 will be a factor of 2 less than the value for x=1.

Answer:

1. Volume measured in Cubic units (to the third power), Only 3-D objects have volume.

2. Parallel lines have the same slope and will never intersect. The slope of perpendicular lines are the negative reciprocals of each other, they will intersect a 90 degrees

3. Secant is 1/cosX (1 over cosine of x), tangent is sinX/cosX(sine of x over cosine of x)

Step-by-step explanation:

Answer:

2x+6y-4

Step-by-step explanation:

First distribute x and 3y

2 times x is 2x

2 times 3 is 6y

(2x+6y) -4

2x+6y-4

Answer:

280/4 = 70 miles per hour. Next, take the unit rate and multiply it by the number of hours you are trying to find. In this case, you are trying to find 6 hours and 30 minutes, but this can also be rewritten as 6.5, since 30 minutes is half an hour. So, in 6.5 hours, the car can go 455 miles

I'm going with the 41....I'm not sure if it's right..

Answer:

C

Step-by-step explanation:

Using the sine ratio in the right triangle

sin x° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{13}{20}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{13}{20}[/tex] ) ≈ 41° ( to the nearest degree )

Step-by-step explanation:

2(heads) + 2(goats) = 140

Heads are given, so we get:

2(52) + 2(goats) = 140

104 + 2(goats) = 140

2(goats) = 36

goats = 18

Since we know the number of goats, we know the number of chickens.

34Chickens and 18 goats.

The diver will be in the air for approximately 0.78 seconds to the nearest hundredth of a second.

The equation that represents the height of the diver above the surface of the pool is given by:

h(t) = -16t² + 6t + 33

where t is the time in seconds and h(t) is the height of the diver above the surface of the pool in feet.

The diver will be in the air until he reaches the surface of the pool, which means that his height will be 0. Therefore, we can set h(t) equal to 0 and solve for t:

-16t² + 6t + 33 = 0

We can use the quadratic formula to solve for t:

t = (-b ± sqrt(b² - 4ac)) / 2a

where a = -16, b = 6, and c = 33.

Plugging in these values, we get:

t = (-6 ± sqrt(6² - 4(-16)(33))) / 2(-16)

t = (-6 ± sqrt(36 + 2112)) / (-32)

t = (-6 ± sqrt(2148)) / (-32)

Simplifying:

t = (-6 ± 46.34) / (-32)

So we have two solutions:

t = (-6 + 46.34) / (-32) ≈ 0.78 seconds

t = (-6 - 46.34) / (-32) ≈ 2.64 seconds

Since the diver cannot be in the air for a negative amount of time, we reject the second solution.

Answer:

104

Step-by-step explanation:

ok so to find the area of this triangle you need to use the number you have witch are 16 and 13 so we wana find the area of one side of the triangle witch it has mark ware it needs to be split and so 16 / 2 is 8 and so we have 2 pairs of 8 and now you multiply hight by width and get 8 x 13 is 104 so we devide that by two in order to get one section of the triandle so 104 / 2 is 52 and thats one side of the triangle and now we add 52 by 52 and get 104
