Tritan played in a football game he caught the ball at the goal line and ran forward 30 yards before he was tackled how could tristansrun be represented as a fraction and decimal of the whole football field

Answers

Answer:

As a fraction = [tex]\dfrac{30}{100}[/tex]

As a decimal = 0.3

Step-by-step explanation:

Recall that: The total yard of a football field = 100 yards

Tritan played in a football game he caught the ball at the goal line and ran forward 30 yards before he was tackled,

As a fraction;

Tristan run can be represented as = number of run from goal-line/ total length of the field

= [tex]\dfrac{30}{100}[/tex]

As a decimal= 0.3

the equation is y=mx+b so if it is

y= 2x+7 that means the slope is 2

Answer:

2

Step-by-step explanation:

This equation is in y=mx+b form.

Slope = m

Esmeralda received a bag of jellybeans that contained a mixture of regular flavored jellybeans and "surprise" jellybeans. The bag advertised that 15% of the jellybeans were "surprise" flavors. If she counted 40 jellybeans in the bag, how many should she expect to be the "surprise" jellybeans?

Answers

Answer:

6 jellybean

Step-by-step explanation:

Given that:

Esmeralda received a bag of jellybean the contains regular flavored jelly beans and surprise jelly bean.

Consider the regular flavored jellybean to be = r;  &

The surprise jelly bean.= s

From the bag, there are 40 jellybeans of which 15% is surprise jellybean.

Therefore the number of expected surprise jellybeans is:

= total number of jellybeans × percentage of surprise jellybean

= 40 × (15 /100)

= 6 jellybean

If  6 surprise jellybean is presented in the bag; then the number of regular flavored jellybean = 40 - 6 = 34 regular flavored jellybean

What is an equation of the line that passes through the points (4, -2) and (8, – 7)?
Put your answer in fully reduced form.

Answers

Answer:

y= -5x/4 + 3

Step-by-step explanation:

To find slope, use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], so m(the slope) = (-7+2)/(8-4) = -5/4.

Now let us use (4,-2) in the equation [tex]y-y_1=m(x-x_1)[/tex].

So y - (-2) = (-5/4)(x - 4) (equation of the line)

y + 2 = -5/4(x - 4)

y + 2 = -5x/4 + 5

y= -5x/4 + 3 (slope-intercept form, also known as fully reduced form)

You could also use (8,-7) instead of (4,-2).

Answer:  She will need 36 yards of material.

Step-by-step explanation:

16 × 2¹/₄ can be done different ways,

First multiply ¹/₄ times 16. that is the same as dividing 16/4 = 4

Then multiply 2 times 16  2×16 = 32

Add 32 + 4 = 36

Henry rode his motorcycle from his house to a friend's house. After riding 10 miles, he realizes he has traveled 2/3 of the way. How far is Bob's house from his friend's house?
A. 20 miles
B. 15 miles
C. 12 miles
D. 25 miles​

Answers

Step-by-step explanation:

2/3 of diatance = 10 miles

3/3 of distance = 10 * (3/2) = 15 miles.

The distance between the houses is 15 miles. (B)

Let the total distance covered= x

Distance covered= 10 miles

According to the question,

2/3 of x= 10

=> 2/3 × x= 10

=> 2x/3= 10

=> 2x= 10× 3

=> 2x= 30

=> x= 30/2

=> x= 15

Bob's house is 15 miles away from Henry's house.

one factor of 8x^3+1 is 2x+1 The other factor is?

Answers

First, write 8x^3 in exponential form (8 is basically the same as 2^3)


So that you have 2^3*x^3+1


Multiply the terms with equal exponents by multiply the bases (1 is basically the same as 1^3)


So that it becomes (2x)^3+1^3



Then, using a^3+b^3 equals (a+b)(a^2-2ab+b^2), factor the expression so that it becomes
(2x+1)((2x)^2-2x+1^2)

Expand the second bracket


So the two factors are (2x+1) and (4x^2-2x+1)

Whats The Answer Giving Brainliest To first Correct AnSwEr:D... Scenario 1When you think of the American Southwest, you probably think of cacti, both big and small. If you were tovisit the American Southwest today, you might be disappointed with the lack of variation among cactusspecies, especially right off the major highways. In 1926, Route 66 was the nation's first major highway toallow visitors to visit the Southwest. Like many tourists, these visitors wanted to take home a memento oftheir travels. Many people would pull over and begin looking for their own living souvenir. Since many of thetourists did not have the necessary tools to extract a spiny cactus out of the soil, they usually had to make aconscious decision about what type of cactus they should dig up. The cacti with too many spines were seenas too difficult to dig out, and the visitors likely didn't have gloves to protect their hands. The cacti with toofew spines were seen as homely and were often overlooked. Therefore, the tourists found a cactus that wasbetween these two extremes. Over the last century, the phenotypic variation within these small cacti haschanged (at least in areas accessible by these highways).

Her staff position at the Resettlement Administration (RA), an agency set up to help tenant farmers during the Depression, was tenuous: since there was no budget for a photographer, Lange had been hired as a clerk-stenographer, and she invoiced her film and travel expenses under "clerical supplies."As Lange drove along the empty California highway that day, she noticed a sign that said Pea-Pickers Camp. Knowing that the pea crop had frozen, she debated for 20 miles before finally turning back. After pulling into the camp's muddy lane, Lange approached a female migrant worker, requested and got permission to photograph her and shot just five exposures. Lange's field notes read in part: "I did not ask her name or her history. She told me her age, that she was 32. She said that they had been living on frozen vegetables from the surrounding fields and birds that the children killed. She had just sold the tires from her car to buy food."Back home, Lange developed the images and, clutching the still-wet prints, told the editor of the San Francisco News that migrant workers were slowly starving to death in Nipomo, California.Migrant Madonna,Rebecca Maksel,2002What is the historical context of these sources?
