Answer:

x=85^{\circ}

Step-by-step explanation:

The sum of the interior angles of any polygon with five sides is equal to (5-2)\cdot 180=3\cdot 180=540^{\circ}. Therefore, we can set up the following equation and solve for x:

115+95+115+130+x=540,\\455+x=540,\\x=\boxed{85^{\circ}}

A rectangle has a width of 5 cm and a length of 10 cm. If the width is increased by 3, how does the perimeter change?
wariber [46]

Answer:

The new perimeter would be 36cm.

Step-by-step explanation:

The perimeter would change because you add 3 to two sides, because the perimeter originally was 5+5+10+10. Now, it's (5+3)+(5+3)+10+10. Which is 36.

Kruka [31]

Answer:

The phenotypic ratio of the offspring will be 100% of purple flowers.

Step-by-step explanation:

Mendel's first law states that if two pure lines are crossed for a given character, the descendants of the first generation will all be equal to each other, phenotypically and genotypically, and phenotypically equal to one of the parents (of dominant genotype).

The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.

We represent the possibilities of hybridization using a Punnett square in the attached picture.

Uppercase letters represent dominant alleles and lowercase letters represent recessive alleles.

Homozygous individuals have the same pair of alleles. (AA, aa)

We can verify that all offspring have a dominant allele, therefore all offspring will have purple flowers.
