to solve)

Answer:

u can search on google the example

Answer:

z = 29°

Step-by-step explanation:

We know that the 3 angles in a triangle always add up to 180°.  So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).  

angle A + angle B + angle C = 180°

59° + 92° + z = 180°

151° + z = 180°

Subtract 151° from both sides of the equation

z = 180° -151°

z = 29°

Answer:

I think the candy cost 51 dollars

Jellybeans: 36$

Gummy worms: 15$

36 + 15 = 51

Step-by-step explanation:

Since jeremiah bought 1 pound for 9 dollar you can minus 9 from the equation which is 51 and since each pound of jelly beans were 9 dollars 9 x 4 = 36 and 51 - 36 is 15 so the cost of the gummy worms are 15 so

either 51 or 36 and 15

Answer:

1.5 inches ; 2 inches ; 2.5 inches

Step-by-step explanation:

Given that the original measurement of the triangular sail is :

6 inches, 8 inches and 10 inches

Scale factor = 1/4

Hence, scaled diagram of the triangular sail :

1/4 * (6 inches, 8 inches, 10 inches)

1/4 * 6 = 1.5 inches

1/4 * 8 = 2 inches

1/4 * 10 = 2.5 inches

Answer:

y = 5.19615 or 3√3

x = 10.3923 or 6√3

also missing angle is 60°.

Step-by-step explanation:

Given :

A carton of 12 eggs or a carton of 18 eggs was the better buy. A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39. Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg The 12-egg carton has the lower unit cost, so it is the better buy.

To Find :

What was her first error.

Solution :

Her first error is to find Unit price of egg in each carton.

To find, unit price we should divide total amount by number of units :

Unit price for carton of 12 eggs, $ (2.39)/12 = $0.199 .

Hence, this is the required solution.

Answer:

She is right, however her explanation is wrong.

In order to find the unit price, you need to divide the amount by the cost.

You will then see that 12 divided by 2.39 < 18 divided by 3.39.

The smaller unit price is obviously the better buy.

Step-by-step explanation:

Answer:

95 degrees is the measure of 3 just like the other angle because they equal each other the angle of 4 you would find out by subtracting 180-95=85. so the measure of 3 is 95 and the measure of 4 is 85

Answer:

j = 24

t = 2

h = 4

Step-by-step explanation:

Three hats, two T-shirts, and one jacket cost $40.

3h + 2t + j = 40

Two hats, two T-shirts, and two jackets cost $60.

2h + 2t + 2j = 60

One hat and three T-shirts cost $10.

h + 3t = 10

3h + 2t + j = 40 (1)

2h + 2t + 2j = 60 (2)

h + 3t = 10. (3)

From (3)

h = 10 - 3t

Substitute into (1) and (2)

3(10 - 3t) + 2t + j = 40 (1)

2(10 - 3t) + 2t + 2j = 60 (2)

30 - 9t + 2t + j = 40

20 - 6t + 2t + 2j = 60

- 7t + j = 40 - 30

-4t + 2j = 60 - 20

-7t + j = 10 (1a)

-4t + 2j = 40 (1b)

Multiply (1a) by 2

-14t + 2j = 20

-4t + 2j = 40

Subtract to eliminate j

-4t - (-14t) = 40 - 20

-4t + 14t = 20

10t = 20

t = 20/10

t = 2

Substitute t = 2 into

h = 10 - 3t

h = 10 - 3(2)

= 10 - 6

= 4

h = 4

Substitute t = 2 and h = 4 into

3h + 2t + j = 40

3(4) + 2(2) + j = 40

12 + 4 + j = 40

16 + j = 40

j = 40 - 16

= 24

j = 24

She hike 1.5 miles  per hour.A common unit of measurement is the mile (mi).

1.609344 kilometers are exactly one unit of length. mile, any of several different measures of distance, such as the statute mile, which has a length of 5,280 feet, is also equivalent to 1,760 yards (1.609 km). It derives from the mile passus, or "thousand paces," of the Romans, which was equivalent to 5,000 Roman feet.

A common unit of measurement is the mile (mi). It is typically used to express the distance between cities, the length of rivers, and the distance between roadways. The letter "mi" stands for the unit mile in writing. Therefore, a marathon race would be roughly 26.3 miles or 26.3 mi in length.

Given ,

1/4hrs=15mins

15mins=3/8miles

60mins=more

60/15 × 3/8

=4/1 × 3/8

=12/8

=1.5miles

Therefore 1.5 miles fast she hike per hour.

The second one: [tex]8x^{2}y+7x^{2}-5y^{2}+3x-2+2x^{2}y-x^{2}-2y^{2}-3x-4[/tex]

Step-by-step explanation:

You have to combine the like terms (any numbers with the same variables and exponents)

[tex]8x^{2}y+2x^{2}y=10x^{2}y, 7x^{2}-x^{2}=6x^{2}, -5y^{2}-2y^{2}=-7y^{2}, 3x-3x=0, -2-4=-6[/tex]

Answer:

Step-by-step explanation:

replace x with 2 then you get -1

Next step replace x with 5 then u get 5

Add 5 and -1. You get four.

The value of  f(2) + f(5) in f(x) = 2x - 5 is 4.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given,  f(x)= 2x-5, therefore f(2) + f(5) can be obtained if we replace x with numerical values 2 and 5 in f(x) which is,

f(2) + f(5) = 2(2) - 5 + 2(5) - 5.

f(2) + f(5) = 4 - 5 + 10 - 5.

f(2) + f(5) = 4
