Answer:

38/50 or 19/25

Step-by-step explanation:

One way could be that you add all the marbles together to get your total marbles; 12 + 10 + 15 + 13 = 50.

Then you add all the colours expect red; 10 + 15 + 13 = 38.

Which would give me 38/50; which simplifed would be 19/25

Imagine fractions as a pie. The bottom number is the total pieces of slices that make up the pie. The top number is how many you are served.

If there are a total of 5 pieces and you get 3 pieces of the pie, is that larger than getting 1 piece of the pie? Yes!

Jen buys sesame bagels and plain bagels. If the ratio of sesame to plain is 1:3 and Jen bought 2 dozen bagels, what percent of b

Ulleksa [173]

Answer:

The number of plain bagels are 18 and it is 75% of the total bagels .

The amount of salt in a plain bagel to that in a sesame bagel is 81.5% .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

Jen buys sesame bagels and plain bagels. If the ratio of sesame to plain is 1:3 and Jen bought 2 dozen bagels .

As one dozens contains 12 items .

Thus

Total number of bagels bought by Jen = 2 × 12

= 24

Let us assume that the x be the scalar multiple of sesame bagels and plain bagels .

Number of sesame bagels = 1x

Number of plain bagels = 3x

Than the equation becomes

x + 3x = 24

4x = 24

$x = \frac{24}{4}$

x = 6

Thus

Number of plain bagels = 3 × 6

= 18

Part value = 18

Total value = 24

Putting all the values in the formula

$Percentage = \frac{18\times 100}{24}$

$Percentage = \frac{1800}{24}$

Percentage = 75 %

Therefore the number of plain bagels are 18 and it is 75% of the total bagels .

As given

Suppose each plain bagel has 0.53 gram of salt, and each sesame bagel has 0.65 gram.

Part value = 0.53 grams

Total value = 0.65 grams

Putting all the values in the formula

$Percentage = \frac{0.53\times 100}{0.65}$

$Percentage = \frac{5300}{65}$

Percentage = 81.5 %

Therefore the amount of salt in a plain bagel to that in a sesame bagel is 81.5% .

Help please!!!! I will really appreciate it please help

Scorpion4ik [409]

Answer:

Correct answer is x = 28°

Step-by-step explanation:

Okay we know Angle A is 2x + 2

Angle B is 90

Angle C is 180 - 148 = 32 ( straight line angle is 180)

Sum of all angles should be 180 in a triangle

which means

A + B + C = 180

2x + 2 + 32 +90 = 180

2x + 124 = 180

2x = 180-124

2x = 56

x = 56/2

x = 28
