Eric is getting his mountain climbing cerificate. There are 63 days that Eric climbs for 2 hours, there are 97 days that he climbs for 3 hours. How many more hours does Eric need to climb until he earns a certificate for climbing 500 hours?

Answers

Answer 1

Multiply 63x2= 126 then multiply 97x3=291
126+291=417. he needs 500 hours now you will subtract 500-417=83 he needs 83 more hours to reach 500

Answer 2

Final answer:

Eric's total hours climbed so far are 417 hours. To meet his goal of a 500-hour certificate, he still needs to climb for 83 additional hours.

Explanation:

The question pertains to Eric's mountain climbing practice. To find how many more hours does Eric need to climb to earn his 500-hour certificate, we need to calculate the total hours he has already climbed by multiplying the number of days he climbed by the number of hours he climbed each day.

So, for the 63 days Eric climbed for 2 hours each day, that's 63 * 2 = 126 hours.

And for the 97 days he climbed for 3 hours each day, that's 97 * 3 = 291 hours.

Now, we add these two amounts together: 126 hours + 291 hours = 417 hours.

Since he is aiming for a 500-hour certificate, we subtract the hours he has already climbed from this total: 500 hours - 417 hours = 83 hours

Therefore, Eric needs to climb for 83 more hours to earn his 500-hour certificate.

Jamie is making a beaded necklace the ratio of blue beads to purple beads is 4:3 if jamie uses 56 blue beads and purple beads to finish her necklace how many of them will be purple

Answers

She will use 42 purple beads.

Explanation
We will use a proportion to solve this.

The ratio of blue to purple beads is 4:3, or 4/3.
We know she uses 56 blue beads and an unknown amount, x, of purple beads. This gives us 56/x.

Together, we have
4/3 = 56/x

Cross multiply:
4*x = 3*56
4x = 168

Divide both sides by 4:
4x/4 = 168/4
x = 42

Answer: 24 beads

Step-by-step explanation:

Jamie is making a beaded necklace having the ratio of blue beads to purple beads as 4:3 and the total beads used by Jamie is 56. This information can be written as:

Ratio of blue heads= 4

Ratio of purple beads= 3

Total ratio of beads= 4+3 = 7

Total beads used = 56 beads

The number of purple beads used will be= 3/7 × 56

= 3 × 8

= 24 beads

The number of purple beads used is 24

the stem and leaf plot represents a set of data what is the largest number in the set?

Answers

2 is the largest number in the set.

To find the largest number in a stem-and-leaf plot, identify the row with the highest stem and the largest leaf in that row.

The largest number in a set represented by a stem-and-leaf plot can be determined by locating the highest stem value and the largest leaf value attached to it. In a scenario where the stem represents units of 100,000 and the leaf represents units of 10,000, as with the example regarding U.S. cities' populations, you would look for the row with the highest stem number and the highest leaf number within that row to find the largest value. For instance, with a stem of 4 and a leaf of 9, one would interpret the largest number as 490,000.

When constructing a stemplot, each data point's stem is written in a vertical column with the leaves arranged to the right. Negative numbers are handled with negative stems, and the leaves are rounded to represent two significant digits. This method creates a clear visual of data distribution, showing values, potential outliers, and general trends.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have,

Total marbles = 24

White marble = 6

Blue marble = 8

Black marble = 7

Red marble = 3

In this Punnett square, what is the ratio of homozygous to heterozygous offspring? In the Punnett square, what percentage of the offspring are homozygous recessive?

Answers

In a Punnet square, the alleles (one letter: either T or t, here) go horizontally across the top for one parent and vertical down the left for the other parent. In the 2 by 2 square (outlined in blue) are the possible offsprings. The genotypes (two letters: TT, Tt, or tt) of the offspring is the combination of the two parent alleles that intersect in that square.

Start by filling in the rest of the box!
1) Since you know the bottom right square is tt, that means both alleles must be t. You already have the allele of the parent on the left filled in, so fill in the top one with t (shown in green).

2) Since you know the top left square in the 2 by 2 box is Tt, one allele from the parent is T and the other allele is t. You're already given T by the top parent, so fill in the box for the left parent with t (shown in purple).

3) Finally fill in the top right box in the 2 by 2. The top parent donates a t allele (green) and the left parent also donates a t allele (purple). The genotype is tt.

Now back to the questions:
1) Homozygous offspring means that for it's genotype, both alleles are the same: either TT or tt. Heterozygous means that the alleles are different: Tt.

Looking at the 2 by 2 box, which shows your possible offspring, two are Tt (heterozygous) and two are tt (homozygous). The ratio is 2:2, which is the same as 1:1.

2) For homozygous alleles, you can either have homozygous dominant or recessive. Usually the problem tells you which allele is dominant, but the dominant allele is usually shown with a capital letter, or T in this problem! That means homozygous dominant is two capital T's, TT, and homozygous recessive is two lowercase t's, or tt. We will be looking for how many are homozygous recessive, or tt.

Looking at the 2 by 2 box, two of the four offspring have the genotype tt. 2/4 = 50%.

The sum of two numbers is 47. The smaller number is 19 less than the larger number. What are the numbers?

Answers

Here’s the equation (n is the unknown number)
n+n+19=47
2n+19=47
Subtract:
2n = 28
Divide:
n = 14
The numbers are 14 and 33

Final answer:

The two numbers are 33 and 14, where 33 is the larger number and 14 is the smaller number that is 19 less than the larger number. Their sum equals 47.

Explanation:

Finding Two Numbers Based on Sum and Difference

The problem given states that the sum of two numbers is 47, and that the smaller number is 19 less than the larger number. To solve this, let's denote the larger number as x and the smaller number as x - 19. The equation representing their sum is:

x + (x - 19) = 47

Combining like terms, we get:

2x - 19 = 47

Adding 19 to both sides gives:

2x = 66

Dividing both sides by 2, we get:

x = 33

So the larger number is 33. Now we can find the smaller number:

33 - 19 = 14

Therefore, the two numbers are 33 and 14.

The small island is located in an isolated area between Hawaii and the Marshall Islands. Scientists believe that an erupting volcano formed the island. The new land mass measures roughly two square miles and rises nearly ten feet above sea level.2Islands form when magma inside the earth spills onto the earths surface. Once magma hits the planets surface, it is called lava. The erupted lava then cools and hardens to form rocks and land. Scientists believe the volcano that created this new island has been erupting under the ocean for hundreds of years. Nevertheless, the lava has only recently risen above the waters surface to form land. Scientists think the new island will expand as the volcano continues to erupt.3The theory of plate movement informs scientists knowledge of volcanoes. Scientists believe the earths crust consists of eight major, as well as dozens of minor, pieces of land called plates. These plates float on a sea of magma that flows under the earths surface. The plates movements cause continents to shift and mountains to form. They are also responsible for earthquakes and volcanic eruptions.4Volcanoes can form in three ways. Some volcanoes form when the earths plates separate and pull apart from each other. The movement allows magma to bubble up in the gap between the plates. The Mid-Atlantic Ridge under the Atlantic Ocean is formed by separating plates. Although few people know about, it is actually the earths longest mountain chain.5Volcanoes can also occur when one plate is forced underneath another. The lower plate melts into magma, which later erupts from the earth as lava. The volcanoes in a part of the Pacific Ocean known as the Ring of Fire were formed in this way.6The final way that volcanoes can occur is when hot spots of magma burn through thin parts of the earths crust. Hot spots formed the Hawaiian Islands and the new unnamed Pacific island. The lava released from hot spot volcanoes typically flows slowly from the volcanos cone.7Scientists plan to continue studying the new volcanic island in the hope of learning more about the forces that shape the earth and its land masses.
