solve the 2 questions!
Answer:
5) we get a=6
6) we get c=8
Step-by-step explanation:
The triangles given are similar.
When the triangles are similar, the ratio of corresponding sides are also similar.
5) If c = 12, find a
We will use the ratio
[tex]\frac{30}{12}=\frac{15}{a}[/tex]
Now cross multiply to find value of a
[tex]30*a=12*15\\a=\frac{180}{30}\\a=6\\[/tex]
So, we get a=6
6. If b = 6.4, find c
We will use the ratio
[tex]\frac{30}{c}=\frac{24}{6.4}[/tex]
Now cross multiply to find value of b
[tex]30*6.4=24*c\\c=\frac{192}{24}\\c=8\\[/tex]
So, we get c=8

A friend has a 83% average before the final exam for a course. That score includes everything but the final, which counts for 25% of the course grade. What is the best course grade your friend can earn? % What is the minimum score would your friend would need on the final to earn a 75% for the course? %
Answer:
[tex]\mathrm{Best\:course\:grade\:possible:\:}87.25\%,\\\mathrm{Minimum\:score\:on\:final\:to\:earn\:at\:least\:a\:75\%\:for\:the\:course:\:}51\%[/tex]
Step-by-step explanation:
Assuming the maximum score for the final is [tex]100\%[/tex], we can multiply each score by its respective course weight and add them together to give a final score. If your friend did receive this maximum score of [tex]100\%[/tex], their overall grade for the course would be:
[tex]83(1-0.25)+100(0.25)=\fbox{$87.25\%$}[/tex].
To find the minimum score they need to earn a 75% for the course, we set up the following equation:
[tex]83(1-0.25)+x(0.25)=75[/tex], where [tex]x[/tex] is the minimum score she needs.
Solving, we get:
[tex]62.25+x(0.25)=75,\\x(0.25)=12.75,\\x=\fbox{$51\%$}[/tex].

Answer:
24% yes yes yes
Answer:
24% or [tex]\frac{6}{25}[/tex]=24%
Step-by-step explanation:
We know that
[tex]\frac{6}{25}[/tex]
Is the same as
6÷25
Then, using long division gives us
0.24
Lastly, multiplying 0.24 by 100 gives us
24
Now add the percent sign
24%

A ladder is leaning against the side of a building and positioned such that the base of the ladder is 17 ft from the base of the building. If the
ladder reaches 23 ft above the ground, how long is the ladder. Round your answer to the nearest tenth
Answer:
The ladder is 28.6 feet long.
Step-by-step explanation:
Given that:
Length of base = 17 feet
Length above the ground = 23 feet
These forms two legs of right angled triangle.
The length of ladder will be the hypotenuse.
Using Pythagorean theorem;
[tex]a^2+b^2=c^2\\(17)^2 + (23)^2 = c^2 \\289 + 529 = c^2 \\c^2 = 818[/tex]
Taking square root on both sides
[tex]\sqrt{c^2}=\sqrt{818}\\c=28.6[/tex]
Hence,
The ladder is 28.6 feet long.
Which problem situation to the equation 72 - 4x = 48

What is h(x) = 7+ 10x + x2 written in vertex form?
Oh(x) = (x - 25)2 - 18
Oh(x) = (x - 5)2 + 32
h(x) = (x + 5)2 - 18
h(x) = (x + 25)2 + 32 free cookie for whoever answers
Answer:
h(x) = [tex](x+5)^{2}[/tex] -18
Step-by-step explanation:
-b/2a is the formula to find the vertex's x coordinate.
-10/2(1) = -5 and "(x+5)" represents a translation to the left 5 units, so that must be the answer

O 6) Missy walks 1/3 mile to school Select all the fractions that are equivalent to 1/3. 1/6 2/6 4/12 3/6 3/4 This is a required question G
Answer:
2/6 and 4/12
Step-by-step explanation:
When you reduce both of these fractions, they come out to 1/3.
Dividing both terms of 2/6 by 2, the greatest common factor (GCF), would equal 1/3.
And dividing both terms of 4/12 by 4, which is the GCF in this case, would equal 1/3.

Answer:
Step-by-step explanation:
a) The interest generated over the 9 months is how much the woman paid for use of the money, then:
[tex]I=C.t.i\\C=3000\\t=9\\i=3.5%=0.035\\I=3000.9.0.035=945\\I=945[/tex]
Therefore , the woman paid $945 for the use of the money.
b) The total amount that she repaid the bank is:
[tex]C_{t} =C+I=3000+945=3945\\C_{t} =3945[/tex]
Finally we have that the woman paid $3945 to the bank

Rodney packs 4 shirts for a trip at random. The closet contains 10 shirts: 5 striped, 3 plaid, 2 solid colored ones. What is the probability that he chose 2 striped and 2 plaid
Answer:
1 / 7
Step-by-step explanation:
Given :
Number of shirts in closet = 10
Number of striped shirt = 5
Number of plaid = 3
Probability of choosing 2 plaid shirts and 2 stripped shirt
Probability = required outcome / Total possible outcomes
Total possible outcomes = 10C4
Required outcome :
2 plaid shirt from 3 = 3C2
2 stripped shirts from 5 = 5C2
Hence,
P(choosing 2 plaid and 2 stripped shirt) :
(3C2 * 5C2) / 10C4
Recall:
nCr = n! / (n-r)!r!
Using calculator :
(3C2 * 5C2) / 10C4
= (3 * 10) / 210
= 30 / 210
= 1 / 7
IS 7 7 Solve for a = √[? [] a a = 4 Enter the number that goes beneath the radical symbol 4 Enter
Answer:
[tex]a=\sqrt{33}[/tex]
Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know b and c we can plug that in to find out what a could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\a^2+4^2=7^2\\a^2+16=49\\a^2=33\\\sqrt{a^2}=\sqrt{33}\\a=\sqrt{33}[/tex]
So a would equal whatever the square root of 33 is.

if a sample size 40 is drawn from the population that has mean 276 and a variance of 81, what is the probability that the mean of the sample will be less than 273?
Answer:
The probability is 0.017429
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)/SD/√n
In this case;
x = 273
mean = 276
SD = √(variance) = √81 = 9
n = 40
Substituting these values into the z-score formula, we have that;
z = (273-276)/9/√40
z = -2.11
So we proceed to get the probability
the probability in this case is;
P( z < -2.11)
We can use the normal distribution table for this
Our answer will be
P( z < -2.11) = 0.017429
