If I have a 40 % and my teacher puts in 3 100% what’s my grade ?

Answers

Answer 1

It would be an A if i'm correct.

Answer 2

Your grade would be an 85%. The way you do the math is to add the 3 100% together to get 300%. Then you would add the 40% to the 300% to get 340%. After, you would divide that percentage by four since you added only four numbers. When you divided, you would get 85%.

Tom mowed lawns for the summer. In June he deposited $120 the first week, $80 the second week, and $75 the following week. Then the mower needed repairs, so Tom had to withdraw $30 from his account. How much money did he have left in his account at the end of June?

Answers

So, let's add up the total amount he made:
120 + 80 + 75 = 275
If he withdrew $30:
275 - 30 = 245
Tom will have $245 at the end of June

Answers

1,3,5 would be right i did this same exact question like 2 minutes ago

Answer:

1- The average rate of change of f(x) is greater than the average rate of change of g(x).

5- The average rate of change of f(x) is -0.1, and the average rate of change of g(x) is -0.25.

Step-by-step explanation:

average rate of change of a function h(x) in the interval [a, b] is computed as follows:

average rate of change = h(b) - h(a)/(b - a)

So, for f(x) (see table):

average rate of change = f(10) - f(4)/(10 - 4) = (0.4 - 1)/(10 - 4) = -0.1

And for g(x) (see figure):

average rate of change = g(10) - g(4)/(10 - 4) = (1 - 2.5)/(10 - 4) = -0.25

A cube that has side lengths measuring 7 inches

Answers

A cube with side lengths measuring 7 inches means that each side of the cube is 7 inches long.

To find the volume of the cube, you multiply the length, width, and height of the cube since all sides are equal:

Volume = length × width × height

For a cube, all these measurements are the same, so you can simply cube the length of one side:

Volume = 7 inches × 7 inches × 7 inches

Volume = 7³ cubic inches

Volume = 343 cubic inches

So, the volume of the cube is 343 cubic inches.

A cube with side lengths measuring 7 inches implies that each side of the cube is 7 inches long.

To find the volume of the cube, we use the formula for the volume of a cube, which is side length cubed.

Since all sides of a cube are equal, we simply cube the length of one side: 7 inches × 7 inches × 7 inches. This equals 7³ = 343 cubic inches.

Therefore, the volume of the cube is 343 cubic inches. In a cube, all sides, angles, and faces are congruent, making it a regular polyhedron with 6 square faces.

Complete Question:

A cube that has side lengths measuring 7 inches.

In a scale drawing a plane has a length of 35 centimeters. The actual length of the plane is 87.5 feet. What is the scale of the drawing?

Answers

If 35 cm represent the length of the plane which is 87.5 ft of the actual plane length. let 1 cm be x ft.
35 cm = 87.5 ft
1 cm = x ft
cross multiply this and the answer is 2.5 ft. Therefore, the scale drawing is 1 cm is 2.5 ft.

The scale of the drawing is [tex]$ \boxed{1 : 0.4} $.[/tex]

To find the scale of the drawing, we need to determine the ratio between the length in the drawing and the actual length.

Let x be the scale of the drawing.

According to the given information, the length of the plane in the drawing is 35 centimeters, and the actual length of the plane is 87.5 feet.

So, we can set up the proportion:

[tex]\[\frac{\text{Length in drawing}}{\text{Actual length}} = \frac{35}{87.5} = x\][/tex]

To find x , we solve for it:

[tex]\[x = \frac{35}{87.5} = 0.4\][/tex]

The scale of the drawing is [tex]$ \boxed{1 : 0.4} $.[/tex]

What must you do if you multiply one number in a ratio by n?

Answers

Answer:

Step-by-step explanation:

If you want to keep the same ratio, you must multiply all of the numbers by n.

A ratio of 1 : 1 will remain 1 : 1 if all the numbers are multiplied by n:

1 : 1 = n : n

_____

Comment on alternate interpretation of the question

There are occasions for multiplying the ratio by n:

x/n = 1/2

To solve this for x, we multiply the ratio (1/2) by n. This multiplies the numerator, but does not change the denominator.

x = n(1/2) = n/2

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%.

In the figure, m and n are rays. Which statements are true? Select each correct answer.
A: m∠3=m∠1
B: m∠2=60°
C: m∠1=60°
D: m∠3=120°

Answers

A is correct because 1 and 3 are vertical angles.

B is correct because there are 180 degrees in a triangle. 180-65-55 = 60. Angle 2 is vertical to the third angle, so angle 2 equals 60.

C is incorrect because it is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 ≠ 60.

D is correct because 3 is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 = 120.

What are the angles formed by 2 intersecting lines?

Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.

Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.

When lines intersect, two angle relationships are formed:

Opposite angles are congruent

Adjacent angles are supplementary

Given data ,

Let the two intersecting lines be m and n

Now , the angles formed are shown in the diagram

where the measure of ∠1 = ∠3 ( Opposite angles are congruent )

Now , the measure of ∠2 = 180° - ( 65° + 55° ) ( angles in a triangle = 180° )

The measure of ∠2 = 60°

So , the measure of ∠3 = 180° - ∠2 ( Adjacent angles are supplementary = 180° )

And , the measure of ∠3 = 120°

Hence , the angles in the intersecting lines are solved

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 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.
