Erla has 28 red and blue marbles. The ratio of red to blue marbles is 1:6.How many blue marbles does Erla have?
Please find the volume of this shape
Answer:
V = 536.8m³
Step-by-step explanation:
A = cross-sectional area
V = prism volume
V = A × length
h = perpendicular height of triangle
h² = 13² - 7²
h² = 169 - 49
h² = 120
h = 10.954...
A = ¹/₂.b.h
A = ¹/₂(14)(10.954...)
A = 76.681...
V = 76.681... × 7
V = 536.768... ⇒ 536.8m³

Area and Circumference of a circle with radius of 5 feet.
Answer:
area is 78.54 and circumference is 31.42
Step-by-step explanation:
Answer:
Area- 78.5 square feet
Circumference- 31.40
Step-by-step explanation:
Formula for Area of Circle:
Area = [tex]pi[/tex] x radius²
or
Area= pi x d
Formula for Circumference of a circle:
2 x pi x r
Radius= half the Diameter
D= diameter
R= radius
Pi= 3.14
Laron is thinking about majoring in business in college because with a bachelor's degree the starting salaries are about $45,000 per year. If a master's degree will allow him to start out at about 15 percent higher, how much can he expect his starting pay to be with a master's degree?
Answer:
$6750 per year
Step-by-step explanation:
15% / 100 = 0,15
0,15 x $45,000 = $6750 he will get per year
Using the given information, match the transformed equation from a parent function of [tex]y=x^2[/tex] or [tex]y=x^3[/tex]
Question and choices below:
Step-by-step explanation:
The general form for a quadratic or cubic equation is:
y = a (x − h)ⁿ + k
If |a| is between 0 and 1, it's a vertical shrink. If |a| is greater than 1, it's a vertical stretch. If a is negative, there's a reflection over the x-axis.
h is the horizontal translation. If h is positive, there's a translation to the right. If h is negative, there's a translation to the left. (Notice the expression in the parentheses is x − h, not x + h, so if it helps, rewrite the equation.)
k is the vertical translation. If k is positive, there's a translation up. If k is negative, there's a translation down.
f(x) = (x + 1)³ − 7
f(x) = 1 (x − -1)³ + -7
a = 1, h = -1, k = -7
This is y = x³ translated 1 unit to the left and 7 units down.
g(x) = -½ (x − 2)³
g(x) = -½ (x − 2)³ + 0
a = -½, h = 2, k = 0
This is y = x³ reflected over the x-axis, vertical shrink of ½, and translated 2 units to the right.
y = -(x − 4)³ − 2
y = -1 (x − 4)³ + -2
a = -1, h = 4, k = -2
This is y³ reflected over the x-axis, translated 4 units right and 2 units down.

A kid traveled a distance of 9 km by bike, and then walked a distance of km.
a.Find the total distance traveled in terms of
b. If the total distance was less than 30 km, form an inequality in , and
then solve it!
Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question;
A kid traveled a distance of 9 km by bike, and then walked a distance of x km.
a.Find the total distance traveled in terms of x
b. If the total distance was less than 30 km, form an inequality in x, and
then solve it!
a) Total distance = distance travelled by bike + distance walked
Total distance = 9km + xkm
Total distance = (9+x)km
b) If the total distance was less than 30 km, the inequality representing this is;
9+x < 30
Subtract 9 from both sides;
9+x-9 < 30-9
x < 21
hence the solution to the inequality is x< 21

Jed is baking shortbread for a bake sale. The recipe calls for 1 1 4cups of flour and 1 2stick of butter. How many cups of flour will Jed need if he uses 3 sticks of butter?
Answer: [tex]7\dfrac12[/tex] cups of flour is required for 3 sticks of butter.
Step-by-step explanation:
We assume that quantity of flour is proportional to butter.
Given : The recipe calls of [tex]1\dfrac14[/tex] cups of flour and [tex]\dfrac12[/tex] stick of butter.
Let [tex]x_1=1\dfrac14=\dfrac{5}{4}[/tex] [tex]y_1=\dfrac{1}{2}[/tex]
For [tex]y_2=3[/tex] , we will find [tex]x_2[/tex] by using formula of direct proportion: [tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]
[tex]\dfrac{\dfrac{5}{4}}{\dfrac12}=\dfrac{x_3}{3}\\\\\Rightarrow\ \dfrac{5}{2}=\dfrac{x_3}{3}\\\\\Rightarrow\ x_3=\dfrac{5}{2}\times3= \dfrac{15}2=7\dfrac12[/tex]
Hence, [tex]7\dfrac12[/tex] cups of flour is required for 3 sticks of butter.
15/2 cups of flour!

Name the triangle with the following characteristics. Sides: 5 cm, 5 cm, 7 cm.
a. equilateral triangle
b. right triangle
c. isosceles triangle
d. scalene triangle
Answer:
[tex]\boxed {\boxed {\sf Isosceles \ triangle}}[/tex]
Step-by-step explanation:
An equilateral triangle has 3 equal sides and angles.
A right triangle contains one right or 90 degree angle.
An isosceles triangle has 2 equal sides and base angles.
A scalene triangle has no equal sides or angles.
The triangle given has the sides of 5 cm, 5 cm, and 7 cm.
Therefore, 2 of the sides are equal and this must be an isosceles triangle.

Jessica earns 800 each month working a part time job. she wants to save a total of 2,400 for collage over a one- year period. what percentage of Jessica's total monthly budget should go to her collage savings to meet her goal
Answer:
25%
Step-by-step explanation:
Given parameters:
Amount earned by Jessica per month = 800
Total savings target per year = 2400
Unknown:
Percentage of savings = ?
Solution:
The total earning per year will be the amount earned per month multiplied by the total number months;
Amount earned in a year = 12 x 800 = 9600
Let the percentage of savings per year = y%
Now;
2400 = [tex]\frac{y}{100}[/tex] x 9600
y = 25%

Use the GCF and the Distributive Property to find the sum. Write each number as a product using the GCF as a factor, and apply the Distributive Property. nothing 34, 51
Answer:
[tex]34 + 51 = 85[/tex]
Step-by-step explanation:
Given
[tex]34 + 51[/tex]
Required
Use GCF and distributive property to determine the sum
34 can be expressed as:
[tex]34 = 2 * 17[/tex]
51 can be expressed as:
[tex]51 = 3 * 17[/tex]
So, the GCF of both numbers is 17
[tex]34 + 51[/tex] can then be expressed as:
[tex]2 * 17 + 3 * 17[/tex]
Apply Distributive Property, we have:
[tex]17(2 + 3)[/tex]
Solving further:
[tex]17 * 5[/tex]
[tex]85[/tex]
Hence:
[tex]34 + 51 = 85[/tex]

you basically take the y value of the first point subtract it from the y value of the 2nd point. you do the same for the x values
Answer:
-2
Step-by-step explanation:
You can use the equation rise over run, which is basically y2-y1 over x2-x1
Y2 is -2 and y4 is 4, x2 is 3 x1 is 0
