Answers

Answer 1

9514 1404 393

Answer:

  a = 3

Step-by-step explanation:

Evaluating the given function at the point, we have ...

  f(-1) = a(-1)^2 +1 = 4

  a +1 = 4

  a = 3

The value of 'a' is 3.

Answer:

1) 42

2) 21

3) 63

Step-by-step explanation:

1)

50% = 0.5

84(0.5) = 42

2)

25% = 0.25

84(0.25) = 21

3)

75% = 0.75

84(0.75) = 63

Three postal workers can sort a stack of mail in 15 minutes, 15 minutes, and 30 minutes, respectively. Find how long it takes them to sort the mail if all three work together.
min

Answers

Answer: 10 minutes

Step-by-step explanation:

x·1/20 + x·1/25 + x·1/100 = 1

Multiply each term by 100 to clear the equation of all fractions

100x/20 + 100x/25 + 100x/100 = 100

5x + 4x + 1x = 100

10x = 100

x = 10

The answer is 10 minutes

What fraction of the whole are the blue piece, the orange piece, the red piece, and the purple piece. How do you know?

Answers

red: 2/4
blue: 1/4
Purple: 1/4

Answer:

blue piece is 1/2 because it takes up half of the square, the purple is only 1/4 because it would take 4 purple to fill the big square and the orange is half of the purple so it takes double of pieces so 8 pieces which is 1/8

Answer:

  C.  35.3 km

Step-by-step explanation:

From your knowledge of right triangles, you know that the hypotenuse is longer than the longest leg and shorter than the sum of the legs.

For this geometry, the distance of interest is longer than 32 km and shorter than 15+32 = 47 km. The only answer choice in the correct range is ...

  35.3 km

Given the diagram below, what is mD?

Answers

Answer:

A

Step-by-step explanation:

Answer:

A. 72

Step-by-step explanation:

There are two ways to solve this problem. First of all, this quadrilateral is a trapezoid because the top two angles are congruent and there is one pair of parallel lines. One way to solve the problem is to remember all trapezoids have a measure of 360. So, mD=360-(108+108+72); this equals 72. Additionally, in a trapezoid, the bottom two angles are always congruent; therefore, angle D must equal 72 degrees.

4≤n−4. a little help?

Answers

Answer:

Just isolate the variable by performing inverse operations. Its like solving an equation but the sign is different.

Step-by-step explanation:

Well add 4 to both sides

8≤n

Thats basically it

Answer:

n ≥ 8

Step-by-step explanation:

We want to isolate n to solve the inequality. To do that, you add 4 to both sides, so 4 + 4 = 8 on the left and n - 4 + 4 = n on the right. That leaves you with 8 ≤ n, or n ≥ 8.

Answers

so since the equation is right by 100 it equals 100 sooo
6x + 52 = 100
now we solve
6x = 48
x = 8
and then for zz it’s 360 - 200
which is 160
divide by 2 so
80
SOOOO
x = 8
z = 80
sorry the explaining sucks ;-;

Answer:

X=8

z=80

Step-by-step explanation:

Okay to find X you gotta find the other angle.

The other angle is 100 which is also vertical To (6x+52)

Vertical angles are equal or congruent so you cna make an eqaution to equal it

6x+52=100

Solve it like a normal equation

x=8

To find Z you gotta realize that 4 angles equal 360 degrees.

We knwo the two vertical angles, 100 and 100. Z is vertical to no name angle so its equal so it can also be Z. Z+Z=2z

Now If you add em all up you should get 360

2z+100+100=360

2z+200=360

Solve from here

z=80

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(2, - 6) * B * (5, - 6), C(5, - 2) and D(2, - 2) . What the perimeter of rectangle ABCD

Answers

Answer:

14 units.

Step-by-step explanation:

Graph all the points on a coordinate grid. Two sides are 4 units each and the other two sides are 3 unites each.

P = 2(l + w)

P = 2(3 + 4)

P = 6 + 8 ← (The distributive property) OR 2(7) ← (Normal way to solve)

P = 14 units and 14 units.

You could also do addition.

P = 3 + 3 + 4 + 4

P = 6 + 8

P = 14 units

What is the volume of a hemisphere with a radius of 3.1 in, rounded to the nearest tenth of a cubic inch?

Answers

The volume of a hemisphere with a radius of 3.1 in. is 62.39 cubic inch

What is a hemisphere?

The Hemisphere is the half part of a sphere.

What is the volume of a hemisphere?

The volume of a hemisphere = (2/3)πr³ cubic units where r is the radius

Given radius is 3.1 in.

volume =  (2/3)π(3.1)³

Could x = - 5 be a solution to the inequality
-6 < 3x + 9 < 21?

Answers

Step-by-step explanation:

[tex]3x + 9 = 3( - 5) + 9 \\ = - 15 + 9 \\ = - 6[/tex]

3x+9 is equals to -6 , not more than based on the inequality, but it is lesser than 21.

However, the solution must fulfil both criteria to be a solution to the inequality. Therefore x = -5 is not a solution to the inequality.
