Samir had 30 dollars to spend on 3 gifts. He spent 9
9
10
dollars on gift A and 5
3
5
dollars on gift B. How much money did he have left for gift C?
Answer:
Gift 1 ($9) Gift 2 ($10)
Step-by-step explanation:
First we know that Samir had 30 dollars to spend on 3 gifts. If he bought gift 1 for $9, and gift 2 for $10. Then Samir should have $11 for gift 3 that he can spend.
9+10=$19, $30-19=$11 Hope This helps! Mark Brainllest if it is correct!
Hence, the money did he have left for gift C is [tex]15.5[/tex].
What is the simplification?
Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), for example Simplification of a fraction to an irreducible fraction.
Here given that,
Samir had [tex]30[/tex] dollars to spend on [tex]3[/tex] gifts. He spent [tex]9.\frac{9}{10}[/tex] dollars on gift A and [tex]4.\frac{3}{5}[/tex] dollars on gift B.
So,
[tex]A=9.\frac{9}{10}\\\\A=\frac{90+9}{10}\\\\A=\frac{99}{10}\\\\A=9.9[/tex]
[tex]B=4.\frac{3}{5}\\\\B=\frac{20+3}{5}\\\\B=\frac{23}{5}\\\\B=4.6[/tex]
To find out the money did he have left for gift C is
[tex]A+B+C=G[/tex]
Here,
[tex]A=9.9\\B=4.6\\G=30[/tex]
Then,
[tex]9.9+4.6+C=30\\\\C=30-9.9-4.6\\\\C=30-14.5\\\\C=15.5[/tex]
Hence, the money did he have left for gift C is [tex]15.5[/tex].

Heather invests $3572 in a retirement account with a fixed annual rate of 5% compounded 4 times per year what will the account balance be after 16 years
Answer:
$7910.3
Step-by-step explanation:
Given data
P=$3572
n=4
T=16 years
R= 5%
The compound interest is expressed as
A= P(1+r/n)^nt
Substitute
A=3572(1+0.05/4)^16*4
A=3572(1+0.0125)^64
A=3572(1.0125)^64
A=3572*2.21453241061

What is Law of Cosines?The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.
The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:
c² = a² + b² - 2ab cos(C)
where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.
Given data ,
Let the triangle be represented as ΔEFG
And , the measures of the sides of the triangle are
g = 4.3 cm
e = 9.1 cm
And , measure of angle ∠F = 116°
where c² = a² + b² - 2ab cos(C)
On simplifying , we get
a² = c² - b² + 2abcos ( C )
78.26 ( cos 116° ) - 4.3² - 9.1² = f²
f² = 135.7344
Taking square roots on both sides , we get
f = 11.7 cm
Hence , the length is f = 11.7 cm

Answer: See explanation
Step-by-step explanation:
John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520.
For the first one that is, 38 × 10 = 380, John is correct. For the second one, that is, 46.52 × 10 = 46.520. John is incorrect. In this case, the first one is correct because John was multiplying by a whole number.
For the second one involving a decimal, John could have shifted the decimal point one place to the right and not add 0 to the end. Then he will get:
46.52 × 10 = 465.2

Given right triangle ABCABC with altitude \overline{BD} BD drawn to hypotenuse ACAC. If BC=10BC=10 and DC=5,DC=5, what is the length of \overline{AC}? AC ?
Answer: [tex]\overline{AC}=[/tex] 12.5
Step-by-step explanation: The triangle ABC and its altitude [tex]\overline{BD}[/tex] is represented in the figure below.
Altitude is a segment of line that link a vertex and the opposite side, forming a right angle.
So, because of [tex]\overline{BD}[/tex], now we have two similar triangles, which means that ratios of corresponding sides are equal:
[tex]\frac{\overline{BD}}{\overline{BC}} =\frac{\overline{AD}}{\overline{BD}}[/tex]
[tex]\overline{BD}^{2}=\overline{BC}.\overline{AD}[/tex] (1)
This is always true for a right triangle and a altitude drawn to the hypotenuse.
Triangle BDC is also right triangle. So, we can use Pythagorean theorem to determine the missing side.
[tex]\overline{BC}^{2}=\overline{CD}^{2}+\overline{BD}^{2}[/tex]
[tex]\overline{BD}^{2}=\overline{BC}^{2}-\overline{CD}^{2}[/tex] (2)
Substituting (2) into (1):
[tex]\overline{BC}^{2}-\overline{CD}^{2}=\overline{BC}.\overline{AD}[/tex]
We want to find f, so:
[tex]\overline{AD}=\frac{\overline{BC}^{2}-\overline{CD}^{2}}{\overline{BC}}[/tex]
[tex]f=\frac{10^{2}-5^{2}}{10}[/tex]
f = 7.5
The length of [tex]\overline{AC}[/tex] is
[tex]\overline{AC}=f+5[/tex]
[tex]\overline{AC}=7.5+5[/tex]
[tex]\overline{AC}=12.5[/tex]
The length of the hypotenuse of triangle ABC is 12.5 units.

Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.42.
A. c(p) = p + 0.42
B. c(p) = 42p
C. c(p) = p/0.42
D. c(p) = 0.42p
Answer:
D. c(p) = 0.42p
Step-by-step explanation:
total cost = .42(P)
Example: 5 lbs
$2.10 = $.42(5)
c(p) = 0.42p <== ur function
Since a pound of sugar increases proportionally to the total cost of sugar bought, then the function can be written as:
c(p) = 0.42p
Where: c(p) = total cost of sugar bought
p = pounds of sugar
c(p) is a function of p, because c(p) depends on p.
Answer: The function rule that gives the total cost is given by
Step-by-step explanation:
Let the number of pounds of sugar be 'p'.
Let the total cost would be C(p).
Cost of each pound = $0.42
So, the function rule would be
Hence, the function rule that gives the total cost is given by

How much would Mariam expect to make in a day when waiting on t t tables?
Answer:
19 tables = $201
t tables = 9t+30
Step-by-step explanation:
the slope would be 9 because she gets $9 for each table (t), 30 would be the y-intercept because she will always get that amount each week.
