BIG POINTS!!!+BRAINLIEST ANSWER!!! BONUS!!!

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

let number of questions in the test be x

9 of the first 10 questions are correct

so only x-10 questions remain

3/10 of the (x-10) = 3/10(x-10) questions are correct

scored 50% for the whole test

so only half of x = x/2 questions are correct

combining the above:

9+3/10(x-10) = x/2

9+3/10x-3=x/2

9-3=(1/2-3/10)x

1/5x=6

x=30

Task I

Sever21 [200]

Answer:

The total money invested in the field will be $\$1,623.80$

Step-by-step explanation:

step 1

Find the dimensions of the field

Let

x -----> the length of the field

y -----> the width of the field

we know that

The perimeter of the field is equal to

$P=2(x+y)$

$P(4.80)=1,584$

$P=330\ m$

$330=2(x+y)$ ----> equation A

$x=4y-10$ ------> equation B

substitute equation B in equation A and solve for y

$330=2(4y-10+y)$

$165=(5y-10)$

$5y=165+10$

$y=35$

Find the value of x

$x=4(35)-10=130$

therefore

The length of the field is 130 meters and the width of the field is 35 meters

step 2

Find the area of the field

The area of the field is

$A=xy$

substitute

$A=(130)(35)=4,550\ m^2$

step 3

Find the number of bags of seed

Divide the area by 460

$4,550/460=9.89\ bags$

Round up to the nearest whole number

$9.89=10\ bags$

step 4

Find the cost of the seed

$(10)(3.98)=\$39.8$

step 5

Find the total money invested in the field

$\$1,584+\$39.8=\$1,623.80$

True or False? A triangle can have side lengths of 3, 3 , and 6

asambeis [7]

Answer:

Step-by-step explanation:

We can check with the Pythagorean Theorem.

a^2 + b^2 = c^2

a and b are always the smaller sides, the legs

c is the longer side, the hypotenuse

3^2 + 3^2 > 6^2

9 + 9 > 36

18 < 36

18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.
