Jason has 34 strawberry scones and 85 raspberry scones.He wanted to make as many identical bags of scones as possible.Each bag should have an equal number of strawberry scones and an equal number of raspberry scones.What is the greatest number of bags Jason can fill?

Answers

Answer: 17

Step-by-step explanation:

We are told Jason has 34 strawberry scones and 85 raspberry scones and that he wanted to make as many identical bags of scones as possible and that each bag should have an equal number of strawberry scones and an equal number of raspberry scones.

To calculate greatest number of bags Jason can fill, we find the factor of 34 and 85 and choose the highest that's common to both.

Factor of 34 = 1, 2 , 17, and 34

Factor of 85 = 1, 5, 17, and 85.

Highest common factor = 17

The answer is 17

Please explain how you got your answer, thank you.

Answers

Answer:

  (-98, 18)

Step-by-step explanation:

We recognize the equation as being in the "point-slope" form.

  y -k = m(x -h) . . . . . . . a line with slope m through point (h, k)

__

Comparing this form to the given equation, we identify the parameters as ...

  k = 18, m = 71.3, h = -98

The point on this line is (h, k) = (-98, 18).

Consecutive interior angles are...


A. Complementary


B. Supplementary


C. Congruent


D. Colinear

Answers

Answer:

Consecutive interior angles will be supplementary

Step-by-step explanation:

As we know that a transversal line is a straight line which tends to intersect two or more parallel lines.

Consecutive interior angles are interior angles that are on the same side of the transversal line. Their sum is 180°.

Hence, Consecutive interior angles will be supplementary

For example, let ∠A and ∠B be the two consecutive interior angles.

As the sum of Consecutive interior angles is 180°, hence they are supplementary.

so the equation becomes

∠A + ∠B = 180°

Let suppose <A and <B are both consecutive interior angles.

Let ∠A is 110°, and we have to determine ∠B.

As the sum of Consecutive interior angles is 180°,

110° + ∠B = 180°

∠B = 180° - 110°

     = 70°

so 70° + 110° = 180°

Therefore, Consecutive interior angles will be supplementary

All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set up equation

(x + 1)° + (10x - 7)° + (8x - 4)° = 180°

Step 2: Solve for x

Combine like terms:                         19x - 10 = 180Isolate x term:                                   19x = 190Isolate x:                                            x = 10

47.9 is what percent of 152?
A)3.2%
B)31.5%
C)0.32%
D)317.3%

Answers

Answer: B

Step-by-step explanation:

Step 1: We make the assumption that 152 is 100% since it is our output value.

Step 2: We next represent the value we seek with x

Step 3: From step 1, it follows that 100%=152

Step 4: In the same vein, x%=47.9

Step 5: This gives us a pair of simple equations:

100%=152(1).

x%=47.9(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100%/x%   = 152/47.9

x= 31.5
