The value of 110 coins, consisting of dimes and quarters, is $20.30. how many of each kind of coin are there?
Answers
0.10d + 0.25q = 20.30
0.10(110 - q) + 0.25q = 20.30
11 - 0.10q + 0.25q = 20.30
-0.10q + 0.25q = 20.30 - 11
0.15q = 9.30
q = 9.30/0.15
q = 62 <==== there are 62 quarters
d = 110 - q
d = 110 - 62
d = 48 <==== there are 48 dimes

What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit?
24.8 units
27.8 units
28.5 units
30.9 units
Answers
Left side: This side is easiest - it's a straight vertical line that's 8 units long.
Top side: If you look carefully, this side is really the hypotenuse of a triangle that is 5 units tall and 9 units long. Using the Pythagorean Theorem, you can calculate the length of the hypotenuse to be 5^2 + 9^2 = c^2 --> c = 10.3
Bottom side: Just like the top side, this side is the hypotenuse of a triangle that is 3 units tall and 9 units long. Pythagoras again: 3^2 + 9^2 = c^2 --> c = 9.5
Add these sides up for the final perimeter: 8 + 10.3 + 9.5 = 27.8
Answer:
The answer would be 27.8
The sum of 2 numbers is 44 the smaller number is 16 less than the larger number what are the numbers
Answers
if you let each number equal x and y we know the sum is 38 so x+y=38
and the smaller is 16 less than the larger
. so if we say the smaller number is 7 then x-16=y
these can be solved as a simultaneous equation. x+(x-16)=38
2x-16=38
2x=54
x=27
(27)-16=y
y=11
so the answer is x=27 y=11
When the measured number 0.0090 is multiplied by the measured number 87.10, the answer has two significant figures?
Answers
The number 0.0090 has two significant figures in it, as we can represent the placeholder zeros (the ones between the decimal and the first 'significant' number - in this case, the 9) with a power of ten: 9.0x10^-3. Additionally, it is a measured number, meaning whatever instrument was used to measure displayed the zero in the ten thousandths place.
The number 87.10 has four significant figures. There are no placeholder zeros between the decimal and a 'significant' number, and it is also a measurement made by an instrument which displayed a zero in the hundredths place.
When numbers are multiplied or divided, the answer should be rounded to the same number of significant figures as the value with the least number of sig figs in the calculation.
0.0090 x 87.10 = 0.7839
= 0.78 rounded to 2 sig figs
or
7.8 x 10^-1 in scientific notation
Jana is on a two-day hike. The function graphed shows the total distance she hiked, in miles, after x hours on the second day.
Select from the drop-down menus to correctly identify the information about Jana's hike provided by the graph.
Answers
The slope is 2.
The slope represents the number of miles hiked every hour.
Answer:
The slope is 2.
Step-by-step explanation:
The function graphed shows the total distance she hiked, in miles, after x hours on the second day.
Seeing at the graph, we have the following points.
(2,8) , (3,10) , (4,12)
For slope we will do the following.
[tex]\frac{10-8}{3-2} =\frac{2}{1}[/tex] = 2
[tex]\frac{12-10}{4-3} =\frac{2}{1}[/tex] = 2
So, the slope is 2.
The slope represents that 2 miles is hiked in each hour.
There are 240 coins in a jar, all dimes and quarters. The value of the coins in the jar is $27.60. There are nine times as many dimes as there are quarters. How many dimes (d ) are in the jar?
Answers
.25 × 30 = 7.50
.10 × 190 = 19
19 + 7.50 = 26.50
Then, you add 4 more quarters which is 27.50 and the 28 dime makes it 27.60

What is the surface area of a sphere with a diameter of 16 cm?
A. 1,024n cm²
B. 32n cm²
C. 256n cm²
D. 128n cm²
Answers
Answer:
The correct option is C. The surface area of a sphere is 256π cm².
Step-by-step explanation:
Given information: The diameter of the circle is 16 cm.
[tex]r=\frac{d}{2}=\frac{16}{2}=8[/tex]
Radius of the circle is 8 cm.
Surface area of a sphere is
[tex]A=4\pi r^2[/tex]
Where, r is radius.
[tex]A=4\pi (8)^2[/tex]
[tex]A=4\pi (64)[/tex]
[tex]A=256\pi[/tex]
The surface area of a sphere is 256π cm². Therefore the correct option is C.

A cheetah can run 103 feet per second. A zebra can run x feet per second. Use the Distributive Property to write and simplify an expression for how much farther the cheetah can run in 10 seconds
Answers
We are given that the rate of cheetah Rc is:
Rc = 103 ft / sec
And the rate of zebra Rz is:
Rz = x ft / sec
We are to find the distance between the two after 10 seconds, that is:
distance = (103 – x) 10
distance = 1030 – 10 x
The expression for how much farther a cheetah can run than a zebra in 10 seconds, given that the zebra's speed is x feet/second, is 1030 - 10x feet.
Explanation:To find out how much farther the cheetah can run in 10 seconds, we need to determine the difference between the cheetah's speed and the zebra's speed, and then multiply by time.
Firstly, the cheetah's speed is 103 feet per second. Let x denote the zebra's speed. The difference in speed is expressed as (103 - x) feet per second.
To find out how much farther the cheetah runs in a given time, we multiply the difference in speed by time. Therefore, the expression for how much farther the cheetah can run in 10 seconds is 10 * (103 - x), which simplifies to 1030 - 10x feet.

The correct answer is option B
--------------------------------------------
Since x = -4 is a vertical line(perpendicular to horizontal), so there is no y-intercept and the slope is undefined.
"A vertical line has undefined slope because all points on the line have the same x-coordinate.
So, the slope is undefined and we also don't have the y - intercept.

Best of luck with your studies!
The correct answer is option B. The equation best represents the line graphed is x = -4.
What is an equation of a line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Since x = -4 is a vertical line(perpendicular to horizontal), there is no y-intercept and the slope is undefined.
A vertical line has an undefined slope because all points on the line have the same x-coordinate.

What is an equation of the line that passes through the points (1 3) and (8 5)? y+1+2/7(x+3), y-5=2/7(x-8), y-1=2/7(x+3), y+5=2/7(x-8)?
Answers
The line passes through the points (1, 3) and (8,5).
Let the equation of the line be
y - y₁= m(x - x₁)
where
(x₁, y₁) is a point on the line.
Calculate the slope of the line.
m = (5 - 3)/(8 - 1) = 2/7
Therefore, if we use (x₁, y₁) = (8, 5), then
y - 5 = (2/7)(x - 8)
Answer: [tex]y-5= \frac{2}{7}(x-8) [/tex]
