Answer:

-2

Step-by-step explanation:

We want to see how long it will take for Lin and Noah to run 1 mile. We will see that:

So we know that:

The time in which they run a single mile is given by the quotient between the time and the distance.

For Lin we have:

[tex]T = \frac{2/5 }{2 + 3/4} h/mi = \frac{2/5}{11/4} h/mi = \frac{2*4}{5*11} h/mi = \frac{8}{55} h/mi[/tex]

So Lin runs a mile in (8/55) hours

For Noah we have:

[tex]T = \frac{4/3}{8 + 2/3} h/mi = \frac{4/3}{26/3} h/mi = \frac{4}{26} mi/h = \frac{2}{13} h/mi[/tex]

Noah runs 1 mile in (2/13) hours.

Answer: 0.2877

Step-by-step explanation:

Given : The proportion of eggs will be damaged in route to the stores = 15% = 0.15

Sample size = 100

Let p be the probability of her eggs will be damaged.

The probability that less than 13% will be damaged is given by :-

[tex]P(p<0.13)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}<\dfrac{0.13-0.15}{\sqrt{\dfrac{0.15\times(1-0.15)}{100}}})[/tex]

[tex]=P(z<-0.56)[/tex]

[tex]=1-P(z<0.56)\\\\= 1-0.7123\\\\= 0.2877[/tex]

Hence, the required probability = 0.2877

Answer:

[tex] \frac{a}{b} = 1.5 [/tex]

Step-by-step explanation:

Given that both ∆s are similar, therefore the ratio of their corresponding sides will be the same.

This means: [tex] \frac{2.1}{a} = \frac{1.4}{b} [/tex].

Since this equation is true, rewrite so that you have [tex] \frac{a}{b} [/tex]

[tex] \frac{2.1}{a} = \frac{1.4}{b} [/tex]

Cross multiply

[tex] a*1.4 = b*2.1 [/tex]

Divide both sides by 1.4

[tex] a = \frac{b*2.1}{1.4} [/tex]

Divide both sides by b

[tex] \frac{a}{b} = \frac{2.1}{1.4} [/tex]

[tex] \frac{a}{b} = 1.5 [/tex]

The value of [tex]\dfrac{a}{b}[/tex] is [tex]1.5[/tex].

Given:

Two triangles in the given figure are similar.

To find:

The value of [tex]\dfrac{a}{b}[/tex].

Explanation:

The corresponding sides of two similar triangles are proportional.

[tex]\dfrac{a}{2.1}=\dfrac{b}{1.4}[/tex]

It can be rewritten as:

[tex]\dfrac{a}{b}=\dfrac{2.1}{1.4}[/tex]

[tex]\dfrac{a}{b}=1.5[/tex]

Therefore, the value of [tex]\dfrac{a}{b}[/tex] is [tex]1.5[/tex].

Question:

A gardener planted flowers of different colors.

3/10 of the flowers are yellow.

3/4 of the remaining flowers are green.

The rest of the flowers are purple.

The gardener planted 119 purple flowers, how many flowers did the gardener plant?

Answer:

[tex]Total = 680[/tex]

Step-by-step explanation:

Represent Yellow with Y, Green with G and Purple with P

[tex]Y = \frac{3}{10}[/tex]

First, we need to determine the fraction of the rest.

[tex]Yellow + The\ Rest = 1[/tex] ---- In terms of fraction

[tex]The\ Rest = 1 - Yellow[/tex]

[tex]The\ Rest = 1 - \frac{3}{10}[/tex]

[tex]The\ Rest = \frac{10 - 3}{10}[/tex]

[tex]The\ Rest = \frac{7}{10}[/tex]

We have that:

[tex]G = \frac{3}{4} * The\ Rest[/tex]

[tex]G = \frac{3}{4} * \frac{7}{10}[/tex]

[tex]G = \frac{21}{40}[/tex]

To solve for the fraction of Purple, we make use of:

[tex]Y + G + P = 1[/tex]

[tex]P = 1 - Y - G[/tex]

Recall that: [tex]Y = \frac{3}{10}[/tex] and [tex]G = \frac{21}{40}[/tex]

So:

[tex]P = 1 - \frac{3}{10} - \frac{21}{40}[/tex]

[tex]P = \frac{40 - 12 - 21}{40}[/tex]

[tex]P = \frac{7}{40}[/tex]

At this point, we have the fraction of each flower as:

[tex]Y = \frac{3}{10}[/tex]

[tex]G = \frac{21}{40}[/tex]

[tex]P = \frac{7}{40}[/tex]

Also, we have that:

[tex]P = 119[/tex]

The relationship between both values of P is:

[tex]\frac{7}{40} * Total = 119[/tex]

[tex]Total = 119 * \frac{40}{7}[/tex]

[tex]Total = \frac{119 * 40}{7}[/tex]

[tex]Total = \frac{4760}{7}[/tex]

[tex]Total = 680[/tex]

Answer:

-25/42

Step-by-step explanation:

you need to make the denominators equal, so find a number that is divisible by both 6 and 7 (i chose 42 because it’s the first number that comes to mind) you then multiply the numerator by the same number.

so -1/6 is multiplied by 7 on top and bottom to become -7/42, and -3/7 is multiplied by 6 of top and bottom to become -18/42.

then you add them together and you get -25/42

if possible you would simplify but for this one it’s not :)

Answer:

Negative Twenty Five over Forty Two.

Step-by-step explanation:

Hey, It looks like you just have to add two fractions. i.e Negative One Sixth (-1/6) and Negative Three Seventh (-3/7).

First Step: Make the denomimators the same.

-1/6 will become -7/42

-3/7 will become -18/42

Second step: Add the two fractions.

-7/42 + -18/42 = -25/42

So there is your answer: -25/42

4 groups of ___ tenths is 1.6.

To find:

The value for the blank.

Solution:

Let the unknown value be x.

4 groups of x tenths is 1.6.

[tex]4x=1.6[/tex]

Divide both sides by 4.

[tex]\dfrac{4x}{4}=\dfrac{1.6}{4}[/tex]

So, 4 groups of 0.4 tenths is 1.6.

Therefore, the required answer for the blank is 0.4.

Answer:

which principle prevents a brach from abusing  its power

Step-by-step explanation:

By answering the above question, we may state that  angle with the smallest measure, the smallest-measured angle

An angle is a form in Euclidean geometry made composed of two rays, referred to as the angle's sides, that converge at a centre point known as the angle's vertex. In the plane where they are positioned, two rays may come together to make an angle. A planar collision produces an angle as well. Dihedral angles are what these are known as. A potential arrangement of two rays or lines that share a termination is called an angle in plane geometry. The Latin word "angulus," which means "horn," is where the English word "angle" originates. The intersection of the two rays, often referred to as the angles' sides, is known as the vertex.
