Answer: -5

Step-by-step explanation:

To solve a positive being added to a negative, just change it to the positive minus the negative. Instead of -12+7, do 7-12. So, your answer would be -5 since 12 less than 7 is negative 5.

timothy is planting a garden. Tulips cost $125 per bub. The total cost c of his gardening supplies is $1.25 per bub b plus $10 f
N76 [4]

Answer:

Independent variable = number of bub (b)

Dependent variable = total cost (c)

Equation: c = $1.25b + $10

Timothy would spend: $20

Step-by-step explanation:

Total cost = c

Number of bub = b

✔️Total cost, c, is dependent on the number of bub, b.

Therefore:

Independent variable = number of bub (b)

Dependent variable = total cost (c)

✔️Equation that describes this situation can be written as:

c = $1.25b + $10

✔️If Timorhy buys 8 bubs, he would spend the following:

Substitute b = 8 into c = $1.25b + $10, and solve for c.

c = $1.25(8) + $10

c = $10 + $10

c = $20

A baseball player hits a pitched ball when it is 4 ft above the ground. The initial upward velocity is 80 ft/s. How
iren [92.7K]

Answer:

t=+4.06

Step-by-step explanation:

when the baseball hits the ground, the height will be 0.

h=0we are given that h=−16t2+64t+4.

this means that the height is 0 when −16t2+64t+4=0.−16t2+64t+4=0divide both sides by 4:−4t2+16t+1=04=0−4t2+16t+1=0 can be solved using the quadratic formula:t=−b±√b2−4ac2a, where at2+bt+c=0.at2+bt+c=−4t2+16t+1a=−4,b=16,c=1t=−b+√b2−4ac2aor−b−√b2−4ac2a−b+√b2−4ac2a=−16+√272−8=−0.06..−b−√b2−4ac2a=−16−√272−8=4.06 (3s.f.)we have 2 values for t:−0.06 and 4.06.

since time cannot be negative, only the positive value can be taken.

this is 4.06, to 3 significant figures.the time taken is 4.06 seconds.

PLEASE DO NUMBER 1 SHOW WORK TOO PLEASE
kirill [66]

Answer:

A) False - not a right angle

B) True - it is a right angle

C) True - it is a right angle

D) False-not a right angle

Step-by-step explanation:

A) a*a+b*b=c*c (Asquared+Bsquared=C squared)

    2*2+ 3*3 = 4*4

   4+9=16

    13 does not equal 16

B) 5*5+12*12=13+13

  25+144=169

  169=169 - True

C) 3*3+4*4=5*5

    9+16=25

     25=25 (True)

D) 4+ Root of 3 = Root of 19

    False - square root of a prime number is irrational
