Answer:

Options (1), (3) and (5)

Step-by-step explanation:

Equation that represents the relationship between the three sides of a triangle is,

a² + b² = c²

Where c = longest side of the triangle

If the length of the given sides satisfy the equation, triangle formed by the sides will be a right triangle.

Option A.

27 in, 36 in, 45 in

(45)² = (27)² + (36)²

2025 = 729 + 1296

2025 = 2025

True.

Option 2.

18 in, 22 in, 28 in

(28)² = (18)² + (22)²

784 = 324 + 484

784 = 808

False.

Option 3

10 in, 24 in, 26 in

(26)² = (10)² + (24)²

676 = 100 + 576

676 = 676

True.

Option 4

20 in, 21 in, 31 in

(31)² = (20)² + (21)²

961 = 400 + 441

961 = 841

False.

Option 5

28 in, 45 in, 53 in

(53)² = (28)² + (45)²

2809 = 784 + 2025

2809 = 2809

True.

Therefore, Options (1), (3) and (5) will be the correct options.

Answer:

43

Step-by-step explanation:

68+44+25=137

180-137=43

the sum of a triangle will always be 180 degrees.

Answer:

43

Step-by-step explanation:

All of the angles in a triangle add up to 180. So 180- (44+68)= 68. The third side of the triangle on the left is 68 degrees. The third side is a linear pair with  the side in the opposite triangle which has a measure of 180-68=(112). Which leaves x=43

I don’t know that answer can you guys help.

Answers

the equation is y = -4x - 2. the equation will be in the form y = mx + b because this is a linear equation. the m is the slope, and this can be found by counting the units between points as rise over run. you can use the first and second points to do this. the rise is -4, and the run is 1, so the slope is -4. the third point is the y-intercept and that is where you find the b value. the coordinates are (0, -2), so the b value is -2.

Megan bought 2 1/4 pounds of bananas for 0.80 per pound and 1 1/2 pounds of strawberries for 1.10 per pound how much more did Megan spend on bananas than on strawberries express the answer as dollars. Cents

Answers

Answer:

$0.15

Step-by-step explanation:

Given that:

Cost of banana per pound = $0.80

Amount of banana bought = [tex]2\frac{1}{4}=2.25\ pounds[/tex]

Cost of strawberries per pound = $1.10

Amount of strawberries bought = [tex]1\frac{1}{2} = 1.5\ pounds[/tex]

To find:

How much more money was spent on bananas than Strawberries.

Solution:

Here, first we need to find how much money was spent on bananas and strawberries.

Then we need to subtract the smaller value from larger value.

From the given values, we can calculate the following:

Cost of banana for 2.25 pounds = $0.80 [tex]\times[/tex] 2.25 = $1.8

Similarly,

Cost of strawberries for 1.5 pounds = $1.10 [tex]\times[/tex] 1.5 = $1.65

Money more spent on bananas = $1.8 -  $1.65 = $0.15

5/8 divided by 3/4?
Pls answer I’ll give u brainliest

Answers

Answer:0.833333333

Step-by-step explanation:

5/8 divided by 3/4 is just 5/8 x 4/3 which is 0.833333333

Divide: 5/8 : 3/4 = 5/8 · 4/3 = 5 · 4/8 · 3 = 20/24 = 4 · 5 /4 · 6 = 5/6

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 3/

4 is 4/3) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 4 gives 5/6.

Crystal works on the weekends! Last Saturday she worked 7.75 hours and on Sunday she worked 8.5 hours. She earns $12 per hour. How much did she earn last weekend?​

She earned $195 last weekend.

Step-by-step explanation:

Expanation
7.75 7 hours (7 x $12 = 95) .75 ( 3/4 of 100) so 3/4 of 60 is 45 now when she works for 30 mins she would earn 6 dollars because it is half of 12. So if it is 45 mins she would earn 9 dollars so if we add it becomes $104

8.5 8 hours and 30 mins because.5 so 8x 12 becomes 96 + 6 ( half of 12) becomes $ 102
